Why Do Zebras Have Stripes?

Why Do Zebras Have Stripes? Scientists Have The Answer -- The Guardian

There have been many explanations for the zebra’s impressive stripes. New research strongly suggests that they have evolved to deter parasitic flies.

The zebra’s striped coat is simultaneously extraordinary and stunning. So wondrous, in fact, that many people have imagined it to be evidence of God’s infinitely artistic hand. Over the years, there have been many more rational explanations, but that all-important scientific consensus has remained elusive.

Charles Darwin certainly found the zebra’s stripes to be a conundrum. In The Descent of Man, he dismissed the idea they could act as camouflage, citing William Burchell’s observations of a herd:

My Comments: It apparently all comes down to biting flies not liking stripes.

NASA Breaks Contact With Russia's Space Agency Because Of Crimea

NASA Suspends Contact With Russia Over Ukraine Crisis -- The Verge

Work on International Space Station will continue.

Citing Russia’s ongoing violations of Ukraine’s sovereign and territorial integrity, NASA told its officials today that the agency is suspending all contact with Russian government representatives. In an internal NASA memorandum obtained by The Verge, the agency said that the suspension includes travel to Russia, teleconferences, and visits by Russian government officials to NASA facilities. NASA is even suspending the exchange of emails with Russian officials.

Ongoing International Space Station activities are exempt from this suspension, however, as are meetings with other countries held outside of Russia that include the participation of Russian officials. The directives come directly from Michael O'Brien, the agency associate administrator for International and Interagency Relations.

Whale Sets Record For Deepest Ever Dive After It Plunges 9,816ft (2,992 Metres) Below The Waves

A study has revealed that the shy Cuvier's beaked whale performs the deepest dives made by any mammal on the planet at 9,816ft (2,992metres) below the waves - the equivalent of just under seven Empire State Buildings - and stays below for 138 minutes

10,000 FEET Under The Sea: Whale Sets Record For Deepest Ever Dive After It Plunges Seven Empire State Buildings Deep -- Daily Mail

* One Cuvier's beaked whale dived 9,816ft (2,992 metres) below the waves and stayed below for 38 minutes
* The equivalent of 6.75 Empire State Buildings placed on top of one another
* Biologists at Scripps Institution of Oceanography in La Jolla, California tagged eight of the whales off San Nicholas Island in southern California
* They are interested in whether the whales display unusual behaviour when they hear sonar emitted from ships

Whales are capable of swimming vast distances across oceans, but they are also expert divers.

And now a study has revealed that the shy Cuvier’s beaked whale performs the deepest dives made by any mammal on the planet.

Scientists were surprised to record one of the mammal's dives, which was 9,816ft (2,992 metres) below the waves.

Why Do The Japanese Wear Surgical Masks?

Why Do Japanese People Wear Surgical Masks? It’s Not Always For Health Reasons -- Rocket News 24

Like kimono and T-shirts with English writing (sometimes vulgar, sometimes comical, always unintelligible), the number of people you’ll see in Japan wearing surgical masks is pretty surprising. Sure, Japan is a hard working society, and the spread of productivity-sapping sickness is always a concern at schools and workplaces, but that doesn’t seem like reason enough for the proliferation of facial coverings that sometimes has Tokyo offices looking more like an operating room.

Health concerns are only part of the equation, though, as recent studies have revealed multiple reasons people in Japan wear masks that have nothing to do with hygiene.

Pentagon Announces A ‘Super-Soldier’ Serum That Will Grant ‘Significant Boost To Troop Performance’

U.S. Military Perfects ‘Super-Soldier’ Serum That Grants ‘Significant Boost To Troop Performance’ -- Guns.com

U.S. Military scientists in conjunction with the office of the Vice President and Warner Music Group have developed a working “super-soldier” serum that “significantly boosts troop performance.”

While President Obama recently confirmed the military is already “building Iron Man,” (see video below) the revelation that a “super-soldier” serum exists comes as nothing short of a surprise. According to military researchers, Project Perspective began over 70 years ago at the height of WWII, but it was only after combining two never-before-tried elements that the experiment truly began to shine.

Ebola Outbreak Is Spreading In West Africa

Ebola Outbreak Causing Panic In West Africa -- Jennifer Lazuta, Special for USA TODAY

DAKAR, Senegal – The rising death toll and the wide spread of the Ebola outbreak in West Africa has sparked fear across the region with at least 80 already having died from the nearly always fatal virus.

"Every day we're reading about it in the newspaper, hearing about it on the radio, and wondering when it's going to come here," said 32-year-old Mossa Bau, who lives in Dakar, Senegal. "Everyone is very scared because, really, it's a dangerous disease and no one has the means to stop it."

The World Health Organization says that as many as 125 people across three countries are now believed to have contracted the highly contagious disease. Senegal shut off its border with Guinea, where the outbreak is believed to have originated, in the hopes of keeping the disease from spreading its way.

America's Beer Map

Researchers analysed a million tweets to see what people preferred to drink, and found huge differences between the coasts

The East Coast Prefers Bud, While The West Goes For Coors: Beer Maps Of America Reveals Top Tipples (And Finds If You Live Near The Coast, You're Probably Drinking Wine) -- Daily Mail

* Researchers analysed a million tweets to find what beers people were drinking
* Found those living near the coast tend to prefer beer over wine
* Washington, Colorado and California prefer wine, while Midwest, Kansas, Oklahoma and Texas prefer beer

The East Coast prefers Bud Light, and those near the coast are more likely to prefer wine over beer, a new study of America's drinking habits has revealed.

Researchers analysed a million tweets to find out which each region prefers.

They found tweet preferences for Bud Light were found mainly in the Eastern half of the US, while preferences for Coors Light originate in the Western half, particularly near Colorado and surrounding states.

How Gmail Happened: The Inside Story Of Its Launch 10 Years Ago Today -- Time

Google's email breakthrough was almost three years in the making. But it wasn't a given that it would reach the public at all

If you wanted to pick a single date to mark the beginning of the modern era of the web, you could do a lot worse than choosing Thursday, April 1, 2004, the day Gmail launched.

Scuttlebutt that Google was about to offer a free email service had leaked out the day before: Here’s John Markoff of the New York Times reporting on it at the time. But the idea of the search kingpin doing email was still startling, and the alleged storage capacity of 1GB—500 times what Microsoft’s Hotmail offered—seemed downright implausible. So when Google issued a press release date-stamped April 1, an awful lot of people briefly took it to be a really good hoax. (Including me.)

My Comment: I am still a Hotmail user .... but I also use a GMail account. But if given the choice .... I will take GMail.

A Yellowstone Volcano Eruption In 2014?

This map from the U.S. Geological Service shows the range of the volcanic ash that was deposited after the biggest of the Yellowstone National Park eruptions around 2.1 million years ago. "These eruptions left behind huge volcanic depressions called “calderas” and spread volcanic ash over large parts of North America," it said. "If another large caldera-forming eruption were to occur at Yellowstone, its effects would be worldwide. Thick ash deposits would bury vast areas of the United States, and injection of huge volumes of volcanic gases into the atmosphere could drastically affect global climate. Fortunately, the Yellowstone volcanic system shows no signs that it is headed toward such an eruption in the near future. In fact, the probability of any such event occurring at Yellowstone within the next few thousand years is exceedingly low."

Yellowstone Volcano Eruption in 2014? Are Animals Fleeing Park As ‘An Alert’? -- Zachary Stieber, Epoch Times

A number of bloggers are posting videos that show bison and other animals allegedly leaving Yellowstone National Park, prompting theories that as earthquakes ramp up the seismic activity will set off the Yellowstone supervolcano.

Two of the main bloggers behind the discussion stress that there’s no way to know when the supervolcano will go off but note that the 4.8 magnitude earthquake that hit on March 30 seemed to set off a reaction from the animals, who are moving for a reason.

U.S. Air Force's X-37B Breaks It's Own Record After Circling The Earth For 470 Days

Mystery Of The Pentagon’s Space Plane: X-37B Breaks Record After Circling Earth For 470 Days - But Won't Reveal What Mission Was For -- Daily Mail

* Spacecraft taken into orbit on a rocket but lands by gliding down to Earth
* Is the third and longest flight for mission which is shrouded in secrecy
* Some analysts suggest it will help support American soldiers in warzones
* Other rumours are circulating that the craft has been kept in space to spy on the new Chinese space station, Tiangong

A U.S. space plane, shrouded in secrecy, has broken its own longevity record by staying in orbit for more than 469 days.

The flight is the third for the X-37B mystery mission and was launched on December 11, 2012, atop an Atlas V rocket at Cape Canaveral.

Little is known about the spacecraft, which is taken into orbit on a rocket but lands like the space shuttle by gliding down to Earth.

A Pill That Helps Adults Learn New Skills As Quickly As Children?

In 2011 thriller Limitless, Bradley Cooper, pictured centre, takes a pill that opens up closed regions of his brain. This boost his intelligence, motor skills and ability to learn new languages

The Real-Life Limitless Pill? Drug Helps Adults Learn As Fast As Children By Making The Brain More 'Elastic' -- Daily Mail

* Donepezil is used to improve memory function in Alzheimer’s patients
* Children learn skills quickly as their brains go through 'critical periods’
* Researchers found donepezil can revert adult brains to these periods
* It increases the 'elasticity' of the brain making it capable of learning rapidly
* Researchers rewired a visually impaired patient’s brain to process images
* The drug works by boosting chemicals in the brain that reduce with age

It may sound like something from 2011 thriller Limitless, but researchers have discovered a pill that helps adults learn new skills as quickly as children.

A professor at Harvard rewired the brain of a visually impaired women to process images by giving her Alzheimer’s drug donepezil.

The pill boosts chemicals in the brain, such as serotonin and acetylcholine, which are both found in high concentrations in the brains of young children.

Seven People Hold The Master Keys To Worldwide Internet Security

Meet The Seven People Who Hold The Keys To Worldwide Internet Security -- The Guardian

It sounds like the stuff of science fiction: seven keys, held by individuals from all over the world, that together control security at the core of the web. The reality is rather closer to The Office than The Matrix

In a nondescript industrial estate in El Segundo, a boxy suburb in south-west Los Angeles just a mile or two from LAX international airport, 20 people wait in a windowless canteen for a ceremony to begin. Outside, the sun is shining on an unseasonably warm February day; inside, the only light comes from the glare of halogen bulbs.

There is a strange mix of accents – predominantly American, but smatterings of Swedish, Russian, Spanish and Portuguese can be heard around the room, as men and women (but mostly men) chat over pepperoni pizza and 75-cent vending machine soda. In the corner, an Asteroids arcade machine blares out tinny music and flashing lights.

Android Has 97 Percent Of Mobile Malware, But Nearly None In The U.S. -- Daily Tech

But almost all of that comes from third party apps stores in Asia and the Middle East

Google Inc. (GOOG) has fought the mobile war against Nokia Oyj. (HEX:NOK1V), Apple, Inc. (AAPL), and Microsoft Corp. (MSFT) (among others) and it has won -- at least in terms of OS market share.

I. Almost No Android Malware in the U.S.; a Whole Lot in China

Roughly four out of every five devices sold around the globe today run a version of Android. And Android is now the world's largest tablet platform as well, in terms of unit share.

But Android also has a massive malware headache. A new report from Finnish security firm F-Secure claims 97 percent of the fast-growing field of mobile malware is Android exclusive. But here comes the twist -- virtually all of that malware comes from smaller Asian and Middle Eastern third-party app stores. - See more at: http://www.dailytech.com

Guinea Faces Ebola Epidemic On Unprecedented Scale, Doctors Warn -- The Guardian

Médecins sans Frontières says lethal virus has broken out in areas hundreds of miles apart, while death toll passes 80

Guinea faces an Ebola epidemic on an unprecedented scale as it battles to contain confirmed cases now scattered across several locations that are far apart, the medical charity Médecins sans Frontières said.

The warning from an organisation used to tackling Ebola in central Africa came after Guinea's president appealed for calm as the number of deaths linked to an outbreak on the border with Liberia and Sierra Leone passed 80.

The outbreak of one of the world's most lethal infectious diseases has alarmed a number of governments with weak health systems, prompting Senegal to close its border with Guinea and other neighbours to restrict travel and cross-border exchanges.

Threat From Global Warming Heightened In Latest U.N. Report -- Reuters

(Reuters) - Global warming poses a growing threat to the health, economic prospects, and food and water sources of billions of people, top scientists said in a report that urges swift action to counter the effects of carbon emissions.

The latest report from the U.N. Intergovernmental Panel on Climate Change (IPCC) says the effects of warming are being felt everywhere, fuelling potential food shortages, natural disasters and raising the risk of wars.

"The world, in many cases, is ill-prepared for risks from a changing climate," the IPCC said on Monday, after the final text of the report was agreed.

China Considering Plans To Cover The Globe With Surveillance Satellites

China mulls global satellite surveillance after flight 370 riddle

China Mulls Global Satellite Surveillance After Flight 370 Riddle -- South China Morning Post

Beijing mulls launching network of dozens of satellites, giving it the ability to monitor the whole world, in wake of lost flight 370

China is considering massively increasing its network of surveillance and observation satellites so it can monitor the entire planet, scientists working on the project said.

The government is mulling building more than 50 orbiting probes, which Chinese researchers said would make the nation's satellite surveillance network on par with, or even larger than, that of the United States.

Frustration with the search for the missing Malaysia Airlines aircraft over the past three weeks had led the project to win strong backing from decision makers in Beijing, the researchers said.

"If we had a global monitoring network today, we wouldn't be searching in the dark. We would have a much greater chance to find the plane and trace it to its final position," said Professor Chi Tianhe, a researcher at the Chinese Academy of Sciences' Institute of Remote Sensing and Digital Earth.

"The plan is being drafted to expand our regional monitoring capability to global coverage."
