Microsoft Warning Over Browser Security Flaw

From The BBC:

Microsoft has issued a "critical" warning over a newly-discovered flaw in Windows.

In a security advisory, the company warned of a loophole that could be used by malicious hackers to steal private information or hijack computers.

The bug potentially affects every user of the Internet Explorer web browser - around 900 million people worldwide.

Microsoft has issued a software patch to defend against attacks, and said it was working to develop a long-term fix.

2.4 Billion Extra People, No More Land: How Will We Feed The World In 2050? -- The Independent

Steve Connor reveals how scientists propose a major policy shift to tackle one of the great challenges of the 21st century.

The finite resources of the Earth will be be stretched as never before in the coming 40 years because of the unprecedented challenge of feeding the world in 2050, leading scientists have concluded in a report to be published next week.

Food production will have to increase by between 70 and 100 per cent, while the area of land given over to agriculture will remain static, or even decrease as a result of land degradation and climate change. Meanwhile the global population is expected to rise from 6.8 billion at present to about 9.2 billion by mid-century.

Vikings' Crystal Clear Method Of Navigation -- New Scientist

Viking sagas may have been more truthful than we realised. Crystal "sunstones" could have helped Viking sailors to navigate even when cloud or fog hid the sun.

Vikings navigated using sundials calibrated to show the direction of the North Pole. While there is no physical evidence for the navigational techniques adopted on cloudy days, there are references in the Viking sagas to "sunstones" being used.

Greenland's Ice Sheet Is Not Melting

Greenland Ice Sheet Is Safer Than Scientists Previously Thought -- The Guardian

New study overturns fears that increased melting could lubricate the ice sheet, causing it to sink ever faster into the sea.

The threat of the Greenland ice sheet slipping ever faster into the sea because of warmer summers has been ruled out by a scientific study.

Until now, it was thought that increased melting could lubricate the ice sheet, causing it to sink ever faster into the sea. The issue was a key unknown in the landmark 2007 report from the Intergovernmental Panel on Climate Change, which pinned the blame for climate change firmly on greenhouse gas emissions from human activities.

How Much Can You Sweat

Never Stop Sweating Jetportal is Jeffrey Montes on Flickr

FYI: How Much Can A Human Body Sweat Before It Runs Out? -- Popular Science

It all depends on the size, physical fitness and hydration of the person in question, but it’s possible to sweat buckets before heatstroke sets in and we pass out. After all, there are about three million sweat glands on the human body (the highest concentration is on our palms), and the average person aggressively working out perspires about 0.7 to 1.5 liters per hour. Theoretically, if we were attached to a treadmill and pumped full of liquids, it’s possible to keep sweating forever.

Who Will Be On Top .... Google Or Facebook?

Will Google Survive Facebook? -- Wall Street Journal

"How can we not be happy?" Google CFO Patrick Pichette asked rhetorically last week as the Internet search giant unveiled stellar earnings and revenue for the fourth quarter and full year 2010.

He got his answer: a swift $25 drop in Google's stock price. Shares closed Friday at $600.99.

On the face of it, Google management and shareholders had plenty to celebrate. In the fourth quarter, sales surged 26%, while profits rose 29%—both above Wall Street's expectations. Growth in Google's core search business accelerated, and Mr. Pichette stressed that newer businesses in display and mobile search were "another growth engine" for the company. Analysts rushed to increase their one-year stock-price targets, with some going as high as $800.

So why the tepid response?

Dinosaurs Survived Mass Extinction by 700,000 Years, Fossil Find Suggests -- Science Daily

ScienceDaily (Jan. 27, 2011) — University of Alberta researchers determined that a fossilized dinosaur bone found in New Mexico confounds the long established paradigm that the age of dinosaurs ended between 65.5 and 66 million years ago.

The U of A team, led by Larry Heaman from the Department of Earth and Atmospheric Sciences, determined the femur bone of a hadrosaur as being only 64.8 million years old. That means this particular plant eater was alive about 700,000 years after the mass extinction event many paleontologists believe wiped all non-avian dinosaurs off the face of earth, forever.

Lack Of Diversity In Grapes Raises Concerns

(Click on Image To Enlarge)

Lack Of Sex Among Grapes Tangles A Family Vine -- New York Times

For the last 8,000 years, the wine grape has had very little sex. This unnatural abstinence threatens to sap the grape’s genetic health and the future pleasure of millions of oenophiles.

The lack of sex has been discovered by Sean Myles, a geneticist at Cornell University. He developed a gene chip that tests for the genetic variation commonly found in grapes. He then scanned the genomes of the thousand or so grape varieties in the Department of Agriculture’s extensive collection.

Much to his surprise he found that 75 percent of the varieties were as closely related as parent and child or brother and sister. “Previously people thought there were several different families of grape,” Dr. Myles said. “Now we’ve found that all those families are interconnected and in essence there’s just one large family.”

Food Inflation Expected To Reach 50% For Some Countries This Year

The world is facing a commodities crisis that could leave millions unable to afford the rising costs of food as population levels soar

Food Prices To Rocket By 50% As Global Hunger Epidemic Causes Riots And Famines -- The Daily Mail

* 'Perfect storm' of issues will bring widespread starvation if nothing is done
* Food prices to rise by 50 per cent over the next decade
* GM crops will be needed to feed the world
* Global population to grow to 9billion by 2050

The cost of food will soar by 50 per cent over the next few decades as the world becomes racked by famine, mass migrations and riots, experts have warned.

The increase will be triggered by the exploding world population, rising cost of fuel and increased competition for water, according to a leading Government think-tank.

Spiralling food prices will push hundreds of millions of people into hunger, trigger mass migration and spark civil unrest, the report warned.

Potential 'Cure' for Type 1 Diabetes? -- Science Daily

ScienceDaily (Jan. 27, 2011) — Type 1 diabetes could be converted to an asymptomatic, non-insulin-dependent disorder by eliminating the actions of a specific hormone, new findings by UT Southwestern Medical Center researchers suggest.

These findings in mice show that insulin becomes completely superfluous and its absence does not cause diabetes or any other abnormality when the actions of glucagon are suppressed. Glucagon, a hormone produced by the pancreas, prevents low blood sugar levels in healthy individuals. It causes high blood sugar in people with type 1 diabetes.

From Live Science:

Robots that evolved from crawling babies into upright adults could help pave the way for better bots.

Using a computer program, researchers at the University of Vermont simulated a population of naive "baby" robots. The robots had to complete various tasks in their virtual environment, such as finding objects and walking toward them. Those robots that performed poorly got deleted, while the best-performing ones remained "alive."

The robots that changed their body forms (like tadpoles growing into frogs) learned to walk more rapidly and developed the most stable gait, the researchers found.

Climate Change Means We Will Be Skiing In Yorkshire Rather Than Sunbathing Under Palm Trees, Experts Warn -- The Telegraph

We are more likely to be skiing in Yorkshire than basking under palm trees, a leading climate change expert has warned as global warming will actually lead to Britain getting colder.

Dr Simon Boxall, of the National Oceanography Survey, said that while the planet as a whole will get much warmer, this country will see temperatures plunge as the ocean currents and weather patterns around the world change.

At the moment north west Europe, particularly Britain, is warmer than it should be because of the effect of the North Atlantic Drift bringing warm water from the Tropics.

From Science Daily:

ScienceDaily (Jan. 26, 2011) — A hurtling asteroid about the size of the Titanic caused the scar that appeared in Jupiter's atmosphere on July 19, 2009, according to two papers published recently in the journal Icarus.

Data from three infrared telescopes enabled scientists to observe the warm atmospheric temperatures and unique chemical conditions associated with the impact debris. By piecing together signatures of the gases and dark debris produced by the impact shockwaves, an international team of scientists was able to deduce that the object was more likely a rocky asteroid than an icy comet. Among the teams were those led by Glenn Orton, an astronomer at NASA's Jet Propulsion Laboratory, Pasadena, Calif., and Leigh Fletcher, researcher at Oxford University, U.K., who started the work while he was a postdoctoral fellow at JPL.

(AP) WASHINGTON - Modern humans may have left Africa thousands of years earlier than previously thought, turning right and heading across the Red Sea into Arabia rather than following the Nile to a northern exit, an international team of researchers says.

Stone tools discovered in the United Arab Emirates indicate the presence of modern humans between 100,000 and 125,000 years ago, the researchers report in Friday's edition of the journal Science.

Will Video Games Make U.S. Spies Smarter?

U.S. Spies May Soon Make Smarter Decisions, Thanks to Video Games -- Discover Magazine

Even U.S. intelligence agents make decidedly unintelligent decisions at times. So it may not come as a surprise that the government is willing to invest in any project that could help agencies spot and correct their own decision-skewing prejudices–even if that project is a video game.

Dubbed “Sirius,” the anti-bias project is the brainchild of the Intelligence Advanced Research Projects Activity (IARPA), a government agency whose mission statement might as well have come from a spy novel: to invest in “high-risk/high-payoff research programs that have the potential to provide our nation with an overwhelming intelligence advantage over future adversaries.”

Wind Power's Dirty Little Secrets -- The Daily Bayonet

A California court tells the naked and ugly truth about a proposed PG&E wind farm, the Manzana Wind Project:

We reject the application because we find that the Manzana Wind Project is not cost-competitive and poses unacceptable risks to ratepayers. We find that the proposed cost of the Manzana Wind Project is significantly higher than other resources PG&E can procure to meet its RPS program goal. Moreover, it will subject the ratepayers to unacceptable risks due to potential cost increases resulting from project under-performance, less than forecasted project life, and any delays which might occur concerning transmission upgrades and commercial online date.

My Comment: More evidence on why wind power cannot be relied upon.

Say Hello To 8 Great Unsolved Mysteries

Science's 8 Greatest Unsolved Mysteries: Progress Report -- Popular Science

In the year 2000, PM asked how eight of the most profound questions in science might (optimistically) be answered before the dawn of the 22nd century. So where are we now, a decade later? Here's the skinny on some of science's greatest mysteries—from attaining immortality and the search for alien life to traveling through time.

The advances in science made over the past hundred years have been nothing short of astounding: We've split the atom and gone to the moon, spliced open the genome and saved countless lives with medicines. Yet as far as we've come, we have a long way to go. We continue to grapple with realties beyond our understanding, from the inner workings of our bodies to the intrinsic mechanics of the universe.

What Can Go Wrong With An Internet "Off" Switch?

Dropped Connection Turning off the Internet could shut down financial networks, and it wouldn't be easy to turn them back on Jamie Sneddon

What Could Possibly Go Wrong: An Internet "Off" Switch -- Popular Science

The last time someone could shut down the Internet was probably in 1969, when it consisted of two computers. But in recent years, concerned with the possibility of a “cyberattack,” Congress has been exploring such an option.

My Comment: The last paragraph is the best point in this report ....

.... A more subtle (or cash-strapped) cyberterrorist might simply fake a cyberattack that would trick the U.S. itself into flipping the switch. No one really knows what would happen then—not only would e-mails go undelivered, but ATMs, stock exchanges and the flow of funds of all kinds could be disrupted. And then we would still face another challenge: how to turn the thing back on.

Indeed.

Shark Nations Failing On Conservation Pledges

Governments are supposed to "encourage full utilisation of dead sharks" - but fins are targeted.

From The BBC:

Many countries whose fishing fleets catch large numbers of sharks have failed to meet a 10-year-old pledge on conserving the species, a report says.

The wildlife trade monitoring network Traffic and the Pew Environment Group say most of the main shark fishing nations do not manage fisheries well.

Ten years ago, governments agreed a global plan to conserve sharks.

An estimated 100 million sharks are killed each year, with nearly a third of species at risk of extinction.

My Comment: Shark fin soup is a delicacy that many people love to order (myself included). Until this changes .... and rising prices probably will change people's desire for this delicacy .... sharks will always be threatened with extinction.

Sharing A Bed with Fido Can Make You Sick

Women are more likely than men to report sleeping in the same bed with their dog, according to a 2005 study by the American Kennel Club. Credit: Dreamstime.

From Live Science:

Sleeping with, kissing and being licked by your pet can make you sick. Although they are not common, documented cases show people contracting infections by getting too cozy with their animals, according to work by researchers in California.

These so-called zoonoses include contracting plague from flea-infested pets, a MRSA (Methicillin-Resistant Staphylococcus aureus) infection, a bacterial infection resistant to multiple strains of antibiotics originating from the canine family, and various parasitic worms.

A Physicist Explains Why Parallel Universes May Exist

From NPR:

Our universe might be really, really big — but finite. Or it might be infinitely big.

Both cases, says physicist Brian Greene, are possibilities, but if the latter is true, so is another posit: There are only so many ways matter can arrange itself within that infinite universe. Eventually, matter has to repeat itself and arrange itself in similar ways. So if the universe is infinitely large, it is also home to infinite parallel universes.

Does that sound confusing? Try this:

Think of the universe like a deck of cards.

Are We Becoming More Stupid? Human Brain Has Been 'Shrinking For The Last 20,000 Years'

Old big head: A 3D image replica of a 28,000-year-old skull found in France shows it was 20 per cent larger than ours

From The Daily Mail:

It's not something we'd like to admit, but it seems the human race may actually be becoming increasingly dumb.

Man's brain has been gradually shrinking over the last 20,000 years, according to a new report.

This decrease in size follows two million years during which the human cranium steadily grew in size, and it's happened all over the world, to both sexes and every race.
