The Future Of Wine: We Need New Breeds Of Grape -- Popular Science

When news broke last week that archaeologist had unearthed a 6,000-year-old winemaking operation in an Armenian cave, many took it as occasion to pat ourselves on the backs—after all, it’s proof that early humans were more civilized than previously thought, evolved creatures that we are. Unfortunately, in the intervening years our grapes haven’t evolved much at all, leaving our winemaking varieties—most of which have been developed from a single species—extremely susceptible to disease and pathogens.

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.

This then warms sea breezes which keep temperatures mild on land.

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.

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.

The current issue of the science journal Nature features an extensive report from a group of Arizona researchers who succeeded in creating a real-time image – one that can be viewed without glasses – from multiple angles. (Just like in "Star Wars"!) The image, the researchers said, is recorded using a battery of cameras:

Atlantic Current Backward During Ice Age

The Gulf Stream brings warm surface water northwards from the tropics to high latitudes, where it cools, sinks and flows southwards at depth. Changes in this Atlantic 'meridional overturning circulation' (MOC) would have profound implications for climate. Credit: National Oceanography Centre

From Cosmos:

SYDNEY: The Atlantic Ocean current, which may be affected by future climate change, today takes heat north to Europe but 10,000 years ago it was weaker and flowed in the opposite direction.

"[The opposite flow in the Atlantic Ocean] explains the presence of huge ice sheets in Europe and North America during that cold climatic period," said César Negre, an environmental scientist at the Autonomous University of Barcelona in Spain, and co-author of the letter in the British journal Nature.

In First Test Of Interstellar GPS, Team Uses Distant Pulsars To Determine Position In Space

Pulsar Positioning It beats rolling down the window and asking for directions. NASA

From Popular Science:

Global Positioning Systems work famously here on the home planet because we control all of the moving parts; put some satellites in the sky, equip a device with the proper hardware to communicate with them, and you can locate yourself just about anywhere. But how would we locate ourselves in deep space? For that kind of spatial location, a team of Italian researchers have devised a way to calculate one’s position in space using pulsars as interstellar navigation beacons.

Cassini Camera Stops Shooting Snaps

From Wired Science:

NASA’s Cassini orbiter, the powerhouse producer of mind-blowing Saturn photos, unexpectedly put itself into “safe mode” at 7 p.m. EDT, Tuesday, Nov. 2. Engineers still don’t know why.

The craft automatically triggers its safe-mode settings whenever something happens that requires attention from mission controllers on the ground. Since going into safe mode, Cassini has stopped collecting science data and sent back only data on engineering and spacecraft health.

That’s normal, said Cassini program manager Bob Mitchell in a press release.

From The Telegraph:

The quest to correct and improve vision is one of man's oldest medical challenges.

For as long as people have had vision problems, efforts have been made to correct them.

But little progress was made beyond the development of glasses and contact lenses before the 20th century.

Spring Break-Ups: Graphic Of Facebook Updates Shows When People Are Most Likely To End A Relationship

The Facebook graphic shows most people break up at Spring Break or Christmas

From The Daily Mail:

If your relationship is rocky and it’s coming up to Christmas, beware: someone might be about to give you some bad news.

A designer who uses hard data to come up with interesting graphics and images has found which points in the year are the most popular for splitting up with partners.

David McCandless pulled information from 10,000 Facebook status updates which used the phrases ‘break up’ or ‘broken up’ and plotted them on a graph.

7 Next-Gen Driving Technologies, Coming Soon To BMW

BMW's next-gen tech could change cars—for better or worse. Here, an iPhone app locates a parked vehicle by GPS from up to 1600 meters away.

From Popular Mechanics:

Fascinating or frightening? Wondrous or worrisome? BMW demonstrates tomorrow's driving innovations, beyond the self-parking car and everyday GPS system.

Munich, Germany—Tomorrow's automotive technology is usually tucked away in research labs—well out of public view. But every once in a while we're granted access to these top-secret incubators, as was the case when we recently paid a visit to BMW's headquarters in Munich.

Gravity Suit Mimics Earth's Pull For Astronauts

Photo: The suit is made of a fabric with carefully tailored stretchiness

From The BBC:

A stretchy suit that mimics the effects of the Earth's gravity has been developed in the US to spare astronauts the ill effects of long missions of weightlessness.

Returning astronauts have lower bone density and muscle mass and can even suffer separation of their vertebrae.

The suit is made of a fabric with carefully tailored stretchiness.

It creates more of a pull at its wearer's feet than at the shoulders, replicating gravity's pull on Earth.
