Scientists have a plan to make tomatoes great again

What happened to the tomato?

It was really one of the first casualties of large-scale agricultural selective breeding. Agricultural companies and mass producers started breeding the tomato in the 1960s for desirable characteristics.  
Firmness helped them ship tomatoes longer distances. Size yielded higher prices. But flavour was left behind, leading to a slow, almost imperceptible decline in taste. The result is the tomatoes we see on the shelves today.  

What are scientists planning to do about it?

An international group of scientists looked at 160 tomato samples from 101 varieties, ranging from modern store-shelf ones to wild, heirloom tomatoes, and asked a bunch of tomato aficionados to rate them based on overall liking and flavour intensity.
From that data, they could narrow down which chemicals in the more-desired tomatoes were actually responsible for the preferred flavour. 
Dozens of flavour compounds were identified, and scientists eventually whittled the group down to 13 different chemicals that were found to be higher in tastier tomatoes.

How does identifying flavour compounds improve the tomato?

That's where genomics — sequencing and analysis of an organism's genome — comes in. Researchers say they were able to identify the specific genes involved in making those 13 different flavour compounds.
One of the reasons tomatoes have lost their flavour is because these compounds are present in very small amounts. The concentration is so small that they are almost undetectable by chemical profiles but definitely detectable by our taste buds. That means that small tweaks in concentration can drastically improve the flavour. 
The plan is to use this new genetic knowledge to help breeders produce higher concentrations of desirable flavour compounds. The hope is that the tomato can still have the durability and size that the commercial producers want but also the flavour consumers desire.
There are some hurdles though — boosting sugar content and maintaining size may be a problem. Here's how Harry Klee, one of the lead researchers from the University of Florida, explains it: 
"Sugars are a challenge because we know that the only way you're going to get more sugar is to reduce the yield or reduce the size of the fruit… There's going to be a trade-off." 
But, let's face it, most of us would be more than willing to buy smaller tomatoes if they have double the flavour.

When can we expect to see these improved tomatoes?

The experiments are already underway. Klee expects that within two years the more flavourful tomato will be ready for commercial viability testing.
It should be noted that there's a huge caveat to all this work: no matter what tomato you buy, even a fancy homegrown organic, wild, heirloom tomato will lose all flavour if you put it in the refrigerator. So if you love your tomatoes but store them in the fridge — the blame rests on you!

Most Facebook hacks are done by friends, finds UBC survey

Want to keep your privacy protected? Keep your eyes on your friends.
A study conducted by Wali Ahmed Usmani, a master’s student at University of British Columbia found that those who you trust the most are the most likely to hack their way into your Facebook account.
The study, which was conducted between from February and March of 2016, looked to find out how common attacks on privacy are, who is most likely to be victimized, who is most likely to attack, why these attacks happen, what the damage is, and how one could possibly protect themselves.
1,308 adult Facebook users, 59% male and 41% female from the United States filled out surveys that included questions asking if they had someone use a device of theirs to access their own Facebook account without their permission, and if they had ever used someone else’s device to access that person’s Facebook account without permission.
“It’s clearly a widespread practice. Facebook private messages, pictures or videos are easy targets when the account owner is already logged on and has left their computer or mobile open for viewing,” said Usmani to ubc.ca.
The survey found that 24% of the group had accessed someone’s personal Facebook account without that person’s permission, and 21% had their Facebook’s violated. Reasons for the insider attacks ranged from practical jokes to invading privacy and reading a person’s messages, or in some circumstances malicious attacks on peoples’ friends using that person’s identity, or even deleting everything off their accounts. A lot of those who told their stores reported a lasting feeling of mistrust, ruined relationships, and embarrassment.
“A sizable fraction of Facebook users seem to have been involved in instances of social insider attacks. The high prevalence of attacks demonstrates a need for effective mechanisms to detect and report these attacks to account owners,” reads the report.
There are multiple ways to protect yourself from outside attacks, such as adding an authenticator, changing passwords often, and ensuring you don’t tell anyone your information. But the inside attacks are a much different animal, the only sure defense is to log out of your Facebook after every use on your devices.
Others made sure to make sure their devices were locked after use and making sure no one know the passwords for their devices.
But having to re-enter my Facebook password every time I wanted to simply scroll through my news feed for a bit (which I do very often throughout the day) or just send a few quick messages would get very tiresome. Researchers involved with the study suggested a passive log that would show how long was spent browsing personal messages and other related information. This would help to discourage people with the possibility of getting caught.
“Jealous snoops generally plan their action and focus on personal messages, accessing the account for 15 minutes or longer and the consequences are significant: in many cases, snooping effectively ended the relationship.” said computer science professor Ivan Beschastnikh, who was a co-author of the report.

Trump overstates inauguration crowd as Women's March appears to draw bigger turnout

There were strong signs across the U.S. that the number of people who attended the Women's March on Washington on Saturday topped those who gathered on Friday to watch U.S. President Donald Trump's inauguration. 
But as over a million people around the world protested in solidarity with events in Washington, both the president and his press secretary took aim Saturday at the media for "attempts to lessen the enthusiasm of the inauguration" and claimed a bigger turnout than the available data suggests. 
The U.S. capital's metro subway stations and train cars were full in many locations on Saturday, while ridership on Friday was well off the numbers from Obama's first inaugural.
Interim D.C. Police Chief Peter Newsham said on Independence Avenue, "The crowd stretches so far that there's no room left to march."
Metro tweeted Sunday that 1,001,616 trips were taken on the rail system the day of the Women's March on Washington. Metro spokesman Dan Stessel had said that on Friday, the day of Trump's inauguration, just over 570,000 trips were taken on the rail system.
No official estimates of the crowd size at the march were immediately available, but the demonstrators appeared to easily exceed the 200,000 organizers had initially expected.
Kevin Donahue, Washington's deputy mayor for public safety and justice, said on Twitter that organizers of the march increased the turnout estimate to over half a million.
On Sunday, Trump and his staff continued their attacks on the media, with adviser Kellyanne Conway saying it was unfair for the media to compare the crowds to President Barack Obama's 2009 inauguration.
ikes
"Photographs of the inaugural proceedings were intentionally framed in a way, in one particular tweet, to minimize the enormous support that had gathered on the National Mall," Spicer's statement readTrump's press secretary said, without evidence, in a statement released Saturday, that the media intentionally framed pictures and video to make the event look smaller.
"These attempts to lessen the enthusiasm of the inauguration are shameful and wrong."
Trump said the inauguration crowd looked to be about 1.5 million people. The National Park Service doesn't provide an official estimate, but such a figure is highly dubious. Other events that filled more of the Mall have not drawn a crowd of that size.
Spicer also stated: "This was the largest audience to ever witness an inauguration — period — both in person and around the globe."
It is not known how many people watched the ceremony on television around the globe, but in the U.S., Nielsen estimates 31 million viewers watched TV coverage.
The 2009 inauguration of Obama, who became the nation's first black president that year, was watched by nearly 38 million viewers, the second-highest number since Nielsen began compiling such figures with Richard Nixon's 1969 oath of office.
Only Reagan drew a bigger U.S. TV inauguration audience, with nearly 42 million viewers tuning in to see the California Republican sworn in for his first term in 1981. 
Trump's total was greater than both swearings-in of Democrat Bill Clinton — 29.7 million and 21.6 million — and the second inauguration of Obama, who drew an average audience of over 20.5 million in 2013, Nielsen said.

Over 1 million protested Trump worldwide

In a global exclamation of defiance and solidarity on Saturday, more than a million people had rallied at women's marches in the Washington, D.C., and cities around the world. The more than 600 "sister marches" around the world were held in conjunction with the main Women's March on Washington.
Many of the women came wearing pink, pointy-eared "pussyhats" to mock the new president. Plenty of men joined in, too, contributing to surprising numbers everywhere from New York, Philadelphia, Chicago and Los Angeles, to Mexico City, Paris, Berlin, London, Prague and Sydney.

LG G6 will have Google Assistant built-in, rumor says

Samsung's Galaxy S8 has long been rumored to feature a revamped virtual assistant called Bixby, and LG's G6 can't afford not to play the AI game. A new rumor out of both companies' home country of South Korea now claims that LG has done something that's pretty surprising in the Android world.
Instead of building its own sub-par virtual assistant, LG has apparently turned to Google for help. As such, the G6 will come with the Google Assistant built-in. Previously, the Google Assistant was exclusive to Google's own Pixel and Pixel XL smartphones (at least in the form that's integrated into the Android system, since it also lives in the Allo chat app and the Google Home device).
The Google Assistant is also an integral part of the upcoming Android Wear 2.0 release, which will be running on the LG Watch Sport and Watch Style, the first wearables to have the new OS version on board. These were co-developed with Google in a program not dissimilar to what the Nexus line used to be for smartphones. The two smartwatches will be unveiled on February 9, it's been rumored.
The LG G6 will be made official on February 26 at MWC in Barcelona. It's reportedly going to become available in early March, beating the Galaxy S8 to the market by about a month.

Super Mario Run will be available on Android in March

Super Mario Run, Nintendo’s first real foray into mobile gaming, won’t be available on Android until March, the company announced in a tweet. In our review of the iOS version we thought the game was fun, but compromised, with surprisingly deep gameplay considering there’s only one control (tap to jump), but a bit repetitious. 
The question now is was it worth it for Nintendo? The company has been fretting about a move to mobile gaming for years, and is set to release two further titles in 2017 (Fire Emblem and Animal Crossing) with more to come in the following years. But while initial interest in Super Mario Run was highestimates from third-parties suggest that only around three percent of users paid for the full game.
Mario hasn’t run out of steam yet, but he seems to be finding mobile gaming a bit of a slog. We’ll see how it goes on Android. You can sign up to be notified with Super Mario Run is released through the Google Play Store.

TAKE A CLOSE LOOK AT FARADAY FUTURE’S (SUPPOSED) TESLA-KILLER

Faraday Future is nothing if not ambitious. The Los Angeles startup promises to do more than make electric vehicles even cooler than Elon Musk did, steal his customers, and deliver a fully autonomous ride. It promises to change how the auto industry works, and how people get around.
Changing the world is hard, especially for a company that has in just the past year lost a slew of key executives, fallen behind on payments for its new factory, and been accused of running a Ponzi scheme by a Nevada official. Company brass remain unfazed. They rolled into CES earlier this month with what they promise will be Faraday’s first production vehicle, the FF91.
Your skepticism is warranted. History has seen no end of upstart automakers with big plans to shake up the industry. Remember Preston Tucker? John DeLorean? Henrik Fisker? Put aside your doubts, and this super-luxe electric limo—which would cost as much as a Bentley—shows some serious style. No wonder it attracted sizable crowds at CES. It’s outfitted for autonomous tech, it sports touchscreens built into the interior, and those doors open themselves at the touch of a button.

Niagara police find Advil mixed in with french vanilla ice cream

Niagara Regional Police are investigating after someone in St. Catharines, Ont., says they found Advil tablets in a sealed container of ice cream.
Police say they were called to home on Jan. 14 after a caller found eight pills mixed into ice cream.
Police say the caller had opened the ice cream to serve it to family but no one had eaten any.
The pills were 400 milligram Advil gel capsules, police say. 
The ice cream was 1.65 litres of Iceberg French Vanilla. The front container numbers are 16279 08:55 and the UPC code is 7 7427611724 2.
The caller thought the ice cream was purchased at either Food Basics on Geneva Street in St. Catharines, or the Freshco on Bunting Road.
Police have notified the manufacturer.

Texas family blame Apple’s FaceTime in suit over fatal crash

SAN JOSE, Calif. — A Texas couple whose five-year-old daughter died in a crash involving a driver who was allegedly using Apple’s FaceTime video chatting app is suing the tech company.
The lawsuit filed this month in Santa Clara Superior Court accuses Apple of not implementing iPhone features that would automatically disable FaceTime based on technology that calculates highway speeds.
Apple hasn’t responded to the lawsuit and didn’t immediately respond to an email Saturday seeking comment.
Moriah Modisette was killed in a 2014 Christmas Eve accident near Dallas. The lawsuit obtained by California television KTLA claims police found FaceTime running on the iPhone of the driver who struck the Modisette family at 65 mph (105 km/h).
The family claims Apple knew the risks of using FaceTime while driving because the company patented “lock-out” technology in 2008.  

Twitter hoax reports Queen Elizabeth died

Many people would argue that 2016 has been the year of celebrity deaths. Others might say it was the year of “fake news.” A story from Britain this week showed it could perhaps be both.
Late Thursday, a Twitter account with the handle @BBCNewsUKI sent out a message claiming Buckingham Palace had announced the death of Queen Elizabeth II, the reigning monarch of the United Kingdom. “Circumstances are unknown,” the tweet read. “More details to follow.”
The news had an air of believability: Elizabeth is 90 years old and has been in poor health recently. This year, for the first time in three decades, she failed to attend a Christmas Day church service near her country home in Norfolk after suffering what was described as a “heavy cold.” The queen has not appeared in public since she fell ill.
Additionally, if the queen were to pass away, it is the BBC that would make the announcement. In fact, Britain’s public service broadcaster is known to hold regular rehearsals in case a member of the royal family dies unexpectedly.
The tweet, of course, was not real. @BBCNewsUKI followed up its tweet with the rather less-BBC-like message, “Love a Tuesday off if the queens dead, announce it before it’s too late.” The account was a fairly obvious fake, and it was soon suspended by Twitter.
But rumors that the queen was dead still sparked a frenzy online, with users rushing to add condolences and others attempting to verify the news.
A number of Twitter users began tweeting that there had been a “media blackout” in an attempt to hide news of the queen’s death from the public. By Friday, it was one of the top trending topics on Twitter - though many of the tweets appeared to be mocking the idea. One curious user even jogged down to Buckingham Palace to look for signs of activity. “Silly twitter,” he concluded.
The incident appeared to confirm that rehearsals for the death of a British monarch, long murmured about by BBC journalists, really exist.
If a “Category 1” royal — a list which would include the queen and her husband, the Duke of Edinburgh, Prince Charles and Prince William — were to die, the BBC has to quickly pull together a remarkably complicated but somber event. Normal broadcasting would be interrupted for an official announcement — probably a statement from Buckingham Palace itself — and the national anthem.
It is also expected that all comedy on the BBC network would be canceled until the after the funeral is held, as it was after the death of King George VI in 1952.

How to unsend your last Gmail message

We’ve all sent an email that we immediately regretted sending. Maybe you broke up with someone rashly. Maybe you told your boss what’s what, only to remember you didn’t have any job security. Thankfully Gmail has made it easy to recall an email before it gets to its destination, provided you act fast enough. Here’s how to recall an email in Gmail in a few easy steps.

1) Go to your Gmail settings
Go to your Gmail and click on the cog on the top right of the screen. Once the menu is open, select the Settings button.</div></div>
2) In the General tab, find the box that says “Enable Undo Send”
The Settings button will take you to the General page. Scroll down about halfway, until you find the Undo Send section between Send and Archive and Stars. Check the box that says “Enable Undo Send.”</div></div>
3) Set your cancellation period 
Gmail lets you choose how long you want the period of time you can cancel an email to be. Do not choose 5 seconds. Give yourself 30 seconds to make this decision. Every email can wait an extra 30 seconds. Your future might depend on you having 30 seconds to think about taking that email back. Don’t mess this up; give yourself 30 seconds.</div></div>
4) Save your changes 
Don’t just click those buttons and leave the window. Make sure you save and confirm the changes before you go on with your life. There’s nothing worse than thinking a feature is working, only to discover it isn’t. You don’t want to find out as you frantically try to cancel an email that you forgot to confirm the feature. Hit save.</div></div>
5) Take your life into your own hands 
You’re all set. Whenever you send an email from now on, you’ll see a “Undo” button added to the normal “Your message has been sent” notification. You now have 30 seconds after every email to hit “Undo.” When you hit it, the email message window will be reopened complete with your original email—you know, the one that could destroy your life. Aren’t you happy you activated this feature? </div></div></div>

The $7.5 billion industry you haven't heard of: Worms

The humble marine worms used to catch fish are some of the most valuable items to come out of the sea, new research shows.
For the first time, scientists have calculated the size and value of this overlooked industry. They estimate 121,000 tons of worms—worth nearly $7.5 billion—are used for bait each year worldwide, most of these dug out of beaches and tidal flats. For comparison, that’s  more than three times the annual revenue generated by the U.S. sushi industry. The estimate is especially impressive since it pertains to the use of various types of marine worms in the ocean, and doesn’t include freshwater fishing or the use of other live bait such as fish.
These worms are “more expensive than any [seafood] you can think of,” says  Gordon Watson, a researcher at the University of Portsmouth. Bloodworms, for example, used to catch fish like striped bass, will put you back more than $80 per pound in the United States, about four times the price of lobster.
Some of the most popular baits include ragworms, lugworms, sandworms and bloodworms. Fishermen use these to catch many different types of fish, including bass, whitefish, cod and other sought-after species, Watson says.
The worms are expensive because it takes a significant amount of effort to dig them up, they can be hard to find and they are obviously essential to snagging the catch that make up fishers’ livelihoods.
To come up with the estimate, described in  a study published in the journal  Fish and Fisheries, Watson and colleagues surveilled several beaches throughout the world to see how often people dug up worms. They also surveyed fishermen about how many worms they use. Knowing the number of fishers worldwide, how much time they spend at sea and how many worms they generally use, they were able to extrapolate in order to come up with a worldwide figure.
These creatures generally live in the sand or silt at beaches and rarely leave their underground homes. They are ideal as bait because they are very smelly and tend to wriggle a lot on hooks, making them attractive and conspicuous to many species of marine fish, Watson says.
This industry has to date received little attention and oversight, something that ought to change, Watson says. Digging up worms can destroy beach areas, pollute the water and stress populations of predators like birds that rely on the animals for food. The study authors suggest that the use of bait worms ought to be regulated as with fish, perhaps limiting the time and place for digging as well as the quantity of worms removed.
The study “will stimulate regulatory bodies to consider what action might be required...for conservation reasons” but also to make bait-extraction itself a “sustainable fishery,” says  Matt Bentley, a marine biologist at Newcastle University Singapore, who wasn’t involved in the study.

Oil rallies as OPEC, rivals reach first output deal since 2001

Oil rose Monday to an 18-month high after OPEC and some of its rivals reached their first deal since 2001 to jointly reduce output to try to tackle global oversupply.
On Saturday, producers from outside the Organization of the Petroleum Exporting Countries, led by Russia, agreed to reduce output by 558,000 bpd, short of the target of 600,000 bpd but still the largest contribution by non-OPEC ever.
That followed the Nov. 30 deal by OPEC to cut output by 1.2 million bpd for six months from Jan. 1, with top exporter Saudi Arabia cutting around 486,000 bpd to curb the supply glut that has dogged markets for two years.
Brent crude futures were up $1.33, or 2.5 percent, at $55.66 per barrel, having hit a session peak of $57.89, the highest since July 2015.
U.S. crude futures settled up $1.33, or 2.6 percent, at $52.83 a barrel. They earlier touched $54.51, also a high going back to July 2015.
"Right now the market is kind of feeding on itself," said Gene McGillian, manager of market research at Tradition Energy in Stamford, Connecticut.
"The market could push another $1 to $2 up to $55, and Brent could go to about $60, but at that point there are some concerns that are going to start to cap the rally."
For the deal to be effective, all parties must stick to their word. Higher prices also raise the chances of other producers boosting output, particularly U.S. shale operators, where rig counts have grown steadily in recent months. U.S. production remains about one million bpd below its peak of 9.6 million reached in 2015, according to U.S. Energy Department data.
PVM Oil Associates strategist David Hufton noted that "as things stand today, no cuts have been made and production is in fact still rising." He said it was difficult to "justify the front-end price surge other than that is where the liquidity is and where speculative players, moving in herds, always prefer to place their bets."

UBER confident that British Columbia will allow ride sharing in the Province

A senior adviser to Uber says he’s confident the B.C. government will allow the ride-sharing service to operate in the province – which is why the company hasn’t pushed its way in, as it has done in other jurisdictions.
Uber has launched in cities across Canada, often against the wishes of local governments, but has yet to enter British Columbia on a large scale.
Instead, despite briefly operating a limousine service in Vancouver in 2012, the company has heeded warnings to stay away as the province examines possible regulations.
“We’re confident that there will be a solution here in partnership with the government that embraces ride sharing – we remain committed to that,” said David Plouffe, a former campaign manager and special adviser to U.S. President Barack Obama who is now chief policy adviser at Uber.
“Our preference is that the government comes up with a solution that embraces ride sharing, and we’re confident that they will. This isn’t a problem for governments to solve. It’s an opportunity to be seized.”
But he said “the clock is ticking” on the issue given that about 200,000 British Columbians have downloaded the Uber app, signifying interest in the service.
Mr. Plouffe is to meet Wednesday with Premier Christy Clark, her office said, but he declined comment on what he would say to the Premier.
He said he was hoping for some policy decisions from the government before the Christmas holidays.
But TransLink Minister Peter Fassbender, who has a key role in the government’s review of ride sharing in advance of any possible legislation, appeared to rule that out Tuesday.
At best, he said, the government might disclose a position on ride sharing by the end of the year after consultation with stakeholders.
“It will be in a form and with sufficient clarity that everyone will know what potential changes could be made,” Mr. Fassbender said.
“It will be clear where government intends to go.”
Uber has been pressuring the province to act, issuing an open letter calling for government action, holding information sessions for prospective drivers and inviting potential customers to sign petitions and voice their support on social media.
Mr. Fassbender said the government won’t be rushed by the company’s campaign.
“They are very aggressive and very committed,” he said.
“They have done a lot of things, run a lot of ads, tried every tool they could to try and force us to move faster than we were prepared to move. We resisted that pressure.”
The government issued a report last month summing up consultations with stakeholders.
Mr. Fassbender said the intent is to honour the existing taxi industry, level the playing field between that industry and ride-sharing companies and protect the public interest.
Mr. Plouffe rejected the suggestion that Uber is overly zealous.
“I don’t think we’re pushy here. Whether it’s Toronto, Ottawa, Edmonton or almost all of India, South America, people are enjoying ride sharing now. I think the urgency is there,” he said.
“This debate has largely been settled in most parts of the world, including most parts of Canada.”
He said Vancouver is the largest city on the continent without ride sharing.
He declined to say exactly how Uber would move into B.C. if given a green light, saying he did not want to give away business secrets.
However, he said it was clear where the demand is – both as a transit option and as a source of income for drivers.
“The outlying cities and towns are really an important part of the discussion because those folks have fewer transportation options to come into the city of Vancouver.”

McCain Onion Rings Recalled Over Possible Glass Contamination

McCain Foods has pulled some of its frozen onion rings from the shelves over concerns they may contain glass.
The Canadian Food Inspection Agency says the New Brunswick-based company voluntarily began the recall late last week.
The recall affects 397-gram bags of McCain frozen onion rings, with an expiry date of Oct. 28, 2015. The affected products have a lot code beginning with V40728.
Anyone who has the product should throw it away or return it to the store, the company told the Toronto Sun.

Obama: Ebola crisis 'spiraling out of control'

President Barack Obama issued a global call to action to fight West Africa's Ebola epidemic on Tuesday, warning the deadly outbreak was unprecedented and "spiraling out of control," threatening hundreds of thousands of people.
Speaking as he unveiled a major new US initiative which will see 3,000 US military personnel deployed to West Africa to combat the growing health crisis, Obama said the outbreak was spreading "exponentially."
"Here's the hard truth. In West Africa, Ebola is now an epidemic of the likes that we have not seen before," Obama said.
"It's spiraling out of control. It is getting worse. It's spreading faster and exponentially. Today, thousands of people in West Africa are infected. That number could rapidly grow to tens of thousands.
"And if the outbreak is not stopped now, we could be looking at hundreds of thousands of people infected with profound political and economic and security implications for all of us."
As well as the military deployment, the US will also set up a command and control center in the capital of Liberia, the hardest-hit country, build new treatment centers and train health workers.
The Ebola epidemic has killed more than 2,400 people in Guinea, Liberia, Nigeria and Sierra Leone this year.
The virus can fell its victims within days, causing severe fever and muscle pain, weakness, vomiting and diarrhea -- in some cases shutting down organs and causing unstoppable bleeding.
The United Nations Security Council is poised to adopt a resolution on Thursday exhorting countries to provide more field hospitals and urgent aid to the crisis-stricken region.
Likely passage of the resolution marks only the third time that the Security Council will vote on a public health crisis after resolutions on AIDS in 2000 and 2011.
The United Nations said nearly one billion dollars would be needed to beat back the worst-ever outbreak of the disease, which is on track to infect 20,000 people by the end of the year.
The world body has set a goal of stopping the spread of Ebola within six to nine months but aid agencies are complaining that help has been too slow.
Ban is planning a "high-level event" on the sidelines of the UN General Assembly next week to draw attention to the crisis.
The capacity of Guinea, Sierra Leone and Liberia to provide even the most basic necessities is "on the brink of collapse," she warned.
The United Nations said the response to the crisis would require $987.8 million (763 million euros), with about half needed for Liberia.
The World Bank meanwhile approved a $105 million grant, part of a $200 million pledge made in early August aimed at helping people cope with the economic impact of the crisis and strengthening public health systems.
"The world needs to do much, much more to respond to the Ebola crisis in these three countries," World Bank President Jim Yong Kim said in a statement.
The UN said if the international community and affected countries respond swiftly and energetically, transmission should begin to slow by the end of the year and halt by mid-2015.
China will send a 59-person mobile laboratory team from its Centre for Disease Control to Sierra Leone, including epidemiologists, clinicians and nurses -- bringing the number of Chinese medics in the country to 174, the WHO said.
The EU, Britain, France and Cuba have also pledged to send medical teams and other aid to the region.
Noting that the known Ebola toll "represents only a fraction of the real number," she stressed that "the ground response remains totally and lethally inadequate."
"The window of opportunity to contain this outbreak is closing," she warned.

The Telephone

Early Telephone Development 

In 1729 English chemist Stephen Gray transmitted electricity over a wire. He sent charges nearly 300 feet over brass wire and moistened thread. An electrostatic generator powered his experiments, one charge at a time. A few years later, Dutchman Pieter van Musschenbroek and German Ewald Georg von Kleist in 1746 independently developed the Leyden jar, a sort of battery or condenser for storing static electricity. Named for its Holland city of invention, the jar was a glass bottle lined inside and out with tin or lead. The glass sandwiched between the metal sheets stored electricity; a strong charge could be kept for a few days and transported. Over the years these jars were used in countless experiments, lectures, and demonstrations.
In 1753 an anonymous writer, possibly physician Charles Morrison, suggested in The Scot's Magazine that electricity might transmit messages. He thought up a scheme using separate wires to represent each letter. An electrostatic generator, he posited, could electrify each line in turn, attracting a bit of paper by static charge on the other end. By noting which paper letters were attracted one might spell out a message. Needing wires by the dozen, signals got transmitted a mile or two. People labored with telegraphs like this for many decades. Experiments continued slowly until 1800. Many inventors worked alone, misunderstood earlier discoveries, or spent time producing results already achieved. Poor equipment didn't help either.
Balky electrostatic generators produced static electricity by friction, often by spinning leather against glass. And while static electricity could make hair stand on end or throw sparks, it couldn't provide the energy to do truly useful things. Inventors and industry needed a reliable and continuous current.
In 1800 Alessandro Volta produced the first battery. A major development, Volta's battery provided sustained low powered electric current at high cost. Chemically based, as all batteries are, the battery improved quickly and became the electrical source for further experimenting. But while batteries got more reliable, they still couldn't produce the power needed to work machinery, light cities, or provide heat. And although batteries would work telegraph and telephone systems, and still do, transmitting speech required understanding two related elements, namely, electricity and magnetism.
In 1820 Danish physicist Christian Oersted discovered electromagnetism, the critical idea needed to develop electrical power and to communicate. In a famous experiment at his University of Copenhagen classroom, Oersted pushed a compass under a live electric wire. This caused its needle to turn from pointing north, as if acted on by a larger magnet. Oersted discovered that an electric current creates a magnetic field. But could a magnetic field create electricity? If so, a new source of power beckoned. And the principle of electromagnetism, if fully understood and applied, promised a new era of communication
In 1821 Michael Faraday reversed Oersted's experiment and in so doing discovered induction. He got a weak current to flow in a wire revolving around a permanent magnet. In other words, a magnetic field caused or induced an electric current to flow in a nearby wire. In so doing, Faraday had built the world's first electric generator. Mechanical energy could now be converted to electrical energy. Is that clear? This is a very important point.
The simple act of moving ones' hand caused current to move. Mechanical energy into electrical energy. Although many years away, a turbine powered dynamo would let the power of flowing water or burning coal produce electricity. Got a river or a dam? The water spins the turbines which turns the generators which produce electricity. The more water you have the more generators you can add and the more electricity you can produce. Mechanical energy into electrical energy.
Faraday worked through different electrical problems in the next ten years, eventually publishing his results on induction in 1831. By that year many people were producing electrical dynamos. But electromagnetism still needed understanding. Someone had to show how to use it for communicating.
In 1830 the great American scientist Professor Joseph Henry transmitted the first practical electrical signal. A short time before Henry had invented the first efficient electromagnet. He also concluded similar thoughts about induction before Faraday but he didn't publish them first. Henry's place in electrical history however, has always been secure, in particular for showing that electromagnetism could do more than create current or pick up heavy weights -- it could communicate.In a stunning demonstration in his Albany Academy classroom, Henry created the forerunner of the telegraph. In the demonstration, Henry first built an electromagnet by winding an iron bar with several feet of wire. A pivot mounted steel bar sat next to the magnet. A bell, in turn, stood next to the bar. From the electromagnet Henry strung a mile of wire around the inside of the classroom. He completed the circuit by connecting the ends of the wires at a battery. Guess what happened? The steel bar swung toward the magnet, of course, striking the bell at the same time. Breaking the connection released the bar and it was free to strike again. And while Henry did not pursue electrical signaling, he did help someone who did. And that man was Samuel Finley Breese Morse.
From the December, 1963 American Heritage magazine, "a sketch of Henry's primitive telegraph, a dozen years before Morse, reveals the essential components: an electromagnet activated by a distant battery, and a pivoted iron bar that moves to ring a bell." See the two books listed to the left for more information.
In 1837 Samuel Morse invented the first workable telegraph, applied for its patent in 1838, and was finally granted it in 1848. Joseph Henry helped Morse build a telegraph relay or repeater that allowed long distance operation. The telegraph later helped unite the country and eventually the world. Not a professional inventor, Morse was nevertheless captivated by electrical experiments. In 1832 he heard of Faraday's recently published work on inductance, and was given an electromagnet at the same time to ponder over. An idea came to him and Morse quickly worked out details for his telegraph.

How practical is Google's driverless car?

Google has been teasing consumers with tidbits about its driverless cars for several years now, but it wasn't until this week that it revealed what this futuristic technology would actually look like.
The prototype is a subcompact car that looks like a computer mouse, has no steering wheel or gas and brake pedals and reaches a maximum speed of roughly 40 kilometres an hour.
Google says that 100 of these prototypes will be built in the Detroit area, and the company expects them to be on the road by next year.
At the Code Conference in Los Angeles this week, Google co-founder Sergey Brin said the self-driving car concept "is about changing the world for people who are not well-served by transportation today."
The futuristic car clearly has its backers, but some analysts, while intrigued, are skeptical about whether this concept is as game-changing as Google thinks.
While they acknowledge a driverless car would have immediate benefits for seniors and the disabled, a self-driving car raises a number of legal and regulatory issues.
Here's a look at some of the applications — and complications — of putting Google's driverless car on the road.
Increased mobility for seniors and people with disabilities
The prototype, which was revealed on Tuesday, has buttons that a passenger presses to begin and end the ride. The passenger sets the route by identifying the destination on a map or by using spoken commands.
In lieu of human operation, the vehicle is outfitted with sensors and cameras mounted on the roof that allows it to analyze what surrounding cars are doing and react accordingly.
The most obvious beneficiaries of a self-driving car would be seniors or the disabled, who may not be able to operate a conventional automobile.
A car such as this would go a long way in restoring some independence for someone with a physical disability, says Tony Dolan, chair of the Council of Canadians with Disabilities and a partial quadriplegic.
As a person with disabilities, he says, "you're always striving for that ability to live as normally as you can." And often as cheaply as you can.
Dolan owns a retrofitted Dodge Caravan minivan, which has a powered ramp, a modified driver's seat, hand controls for acceleration and braking, and a spinner knob on the steering wheel.
It cost him $43,000 US, and he says he had to buy it in the U.S. because the cheapest comparable vehicle he could find in Canada would have cost $68,000 CDN.
Dolan acknowledges that Google's self-driving car would alleviate some of the issues that prohibit many disabled people from driving, but he is concerned about the potential cost. (Google hasn't announced a price tag.)
"The first thing a person with a disability would say about the Google car is, Oh, that's great – but can I afford it? How am I going to pay for that?"
Not necessarily a fun ride
Thilo Koslowski, an automotive analyst with the Gartner consultancy group, says that with a current top speed of 40 km/hr (25 mph), the Google car would not make a particularly effective or fun consumer vehicle.
While there is undoubted curiousity about a car that drives itself, most people still prefer to drive themselves. Koslowski cites a recent poll that showed 35 per cent of respondents would be interested in purchasing such a vehicle, while the rest still preferred a traditional car.
Koslowski says he sees a greater potential for the Google car as an automated taxi or a means to transport goods. He also believes that it could be a valuable mode of transport in low-traffic areas, such as universities, factories or airports.
"There is an opportunity for these kinds of self-driving vehicles to be used at lower speeds on campuses or very specific city areas," says Kozlowski.
And while there may well be greater consumer interest in the future, he suggeststhose vehicles "would have to look very different from the prototype that was shown" this week.
Street legal?
Champions of driverless cars say they would nullify speeding, drunk driving and distracted driving, the prime causes of automobile accidents.
However, there are currently very strict regulations governing the use of these sorts of vehicles on the streets in both Canada and the U.S.
Koslowski points out that the state of California recently announced that in order for a self-driving car to be on the street, there must be two certified engineers sitting in the front seat in order to assume control in case things go awry.
Peter Henein, a product liability lawyer and partner at the Toronto firm Cassels Brock & Blackwell, also sees a number of liability issues with a concept such as this.
Because the vehicle is wholly automated, Henein says the most obvious concern is computer error or failure. As well, because the car relies on an internet connection to identify and navigate to its destination, a drop in the signal could bring the car to a halt — possibly in a very precarious situation.
"If the map is being updated remotely, and there's a lack of connectivity, the car may not know where to go and then the car may not move," says Henein.
Henein also points out that the current prototype is a small car with little apparent safety protection, and would be unlikely to survive a collision with a large truck.
"That doesn't make the [driverless] vehicle dangerous, but it means you have to carefully regulate where it can be driven."
Another question with the car is the liability when a vehicle such as this gets into an accident — would it be the fault of the passenger, the owner or the manufacturer?
A spokesperson for the Insurance Bureau of Canada says it's "too early for us to comment on the insurance implications of the Google driverless car."
Henein says determining liability in the case of an accident between a driverless car and a conventional car would be no different than a collision between two conventional automobiles.
It would require an investigation of the specific circumstances and a determination of whether the accident was created through the actions of the people in the vehicle or a malfunction of the vehicle itself.
'A whole other set of data'
Because the car is fully automated and reliant on geo-location information to determine its routes, the vehicle's computer — and, by extension, Google — will inevitably gather data on passengers habits, Matt Braga, a Canadian tech journalist, told CBC News.
Google currently collects data on consumers through its search engine and email services, which it sells to third parties. Braga says that the self-driving car could provide Google with even more personal information.
"You have this company that already knows things like your purchasing behaviour and who you talk to.
"They'll now have this extra data. They'll know things like, 'Stacy goes to the gym every Thursday,'" Braga said.
"It's a whole other set of data that could be exciting or terrifying."

'I had to step on my friends' bodies to escape': mine survivor

Murat Yokus may have escaped Turkey's deadliest mine explosion, but he is unable to erase the memories of his friends falling one by one to the ground, suffocated by thick fumes that engulfed the tunnels where they were trapped.
"I had step on the bodies of my friends to escape, I had to trample on them," he recounted, his eyes swimming with tears, five days after the tragedy which claimed 301 lives.
The 29-year-old was among 485 miners who managed to get out alive from the explosion and fire in a coal mine in the western town of Soma on Tuesday.
And only just.
"What happened is indescribable," Murat recalled.
"I was about to get out of the mine to go home when we saw fumes arriving," he said. "At first, my boss told us to wait, but we started to get impatient."

About a hundred of them were crammed in an area of 300 square metres (1,076 square feet).
And when he learnt that colleagues who were located in another part of the mine had all died from asphxiation, he decided to disobey his boss's orders.
"I told myself 'I am not going to die here, not now'," Murat said.
"I took the oxygen mask that I had not used until then and I started to walk. When I looked back, I saw many of my friends on the ground."
They were "suffocating, fighting to survive like sacrificial animals."
"They were struggling against death."
Convinced then that he would breathe his last underground, Murat said he thought of "his two young children, his wife, his family".
"I recited my last prayer," before passing out, he said.
Luckily, he was quickly evacuated.
As he was carried out by rescue workers, Murat regained consciousness and chose to walk out on his own.
"You cannot imagine the panic, my colleagues pacing back and forth, the stress, the fear," he said.
Even if miners are aware that theirs is a dangerous job, Yokus said no one is ever really prepared for such an accident.
A preliminary expert report on the accident, obtained by the Milliyet newspaper, pointed to several safety violations in the mine, including a shortage of carbon monoxide detectors and ceilings made of wood instead of metal.
But Yokus, who risked his life for 800 euros a month, would not criticise his company or question if safety standards had been met in the mine.
Despite everything, he is planning to go back underground for another ten years in order to qualify for an early retirement.
"We cannot do anything else. There is no farming here, no companies, no other jobs," said Yokus, whose father also worked as a miner.
"But I will go to another mine," he said.
"In this one, I have lost too many friends to be able to step in there again."

Ottawa seeks public input on wireless radiation

TORONTO - Health Canada has opened an online public consultation process so Canadians can comment on proposed updated guidelines governing safe exposure to radiofrequency waves emitted by cellphones and other electronic devices.
Called Safety Code 6, the draft revised guidelines have been posted on Health Canada’s website — http://www.hc-sc.gc.ca/ewh-semt/consult/_2014/safety_code_6-code_securite_6/index-eng.php — which is open for comment from Canadians until July 15.
The federal department said Friday it will consider comments related to the scientific and technical aspect of Safety Code 6 in the development of its final revised guidelines, expected to be published this fall.
Recommended limits to exposure to radiofrequency waves are based on established scientific evidence and provide protection against all known adverse health effects, said Health Canada, noting that Canada’s limits are consistent with those in such countries as the United States, Japan, Australia and New Zealand.
The public consultation follows an April 1 report by a Royal Society of Canada expert panel on Safety Code 6, which is aimed at protecting the health of workers and the general public.
The panel was asked by Health Canada to recommend any necessary changes to the code following a review of the latest research on adverse health effects linked to radio waves from mobile phones, Wi-Fi equipment, cellular phone towers and TV/radio broadcast antennas.
While the eight-member panel concluded that current exposure limits are designed to avoid all known health hazards and no additional precautionary measures should be introduced, there was one caveat.
Panel members said Health Canada should pursue research aimed at determining if there is a link between exposure to radiofrequency waves from ubiquitous wireless devices and cases of cancer.
Paul Demers, the director of Toronto's Occupational Cancer Research Centre who chaired the panel, said at the time that studies investigating a potential association between exposure to radio waves and the development of cancer have had inconsistent results.
The non-profit group Canadians for Safe Technology, whose stated goal is to educate Canadians and policy makers about the dangers of exposure to unsafe levels of radiofrequency radiation, reacted angrily to the findings.
The organization accused the panel of siding with the wireless industry and ignoring scientific data warning of health risks related to the technology.
Health Canada said the proposed update to Safety Code 6, which was reviewed by the Royal Society panel, includes radiofrequency exposure limits that are more restrictive than those in the current version, written in 2009.
