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.

Man's Migration Out Of Africa More Complicated Than Thought


Ancient Tools May Mark Earlier Path Out Of Africa -- Wired Science

The bodies are still missing, but a prehistoric toolkit discovered in the United Arab Emirates has led some archaeologists to propose a more complex scenario for humanity’s emigration out of Africa.

Uncovered at a Jebel Faya rock shelter, just west of the Straits of Hormuz at the mouth of the Persian Gulf, the tools are 125,000 years old. Previous estimates placed the dispersal of modern humans from North Africa around 70,000 years ago. If correct, this new study indicates that humans in eastern Africa left earlier, and traveled to Arabia.

Efficiency Could Cut World Energy Use Over 70 Per Cent -- New Scientist

Simple changes like installing better building insulation could cut the world's energy demands by three-quarters, according to a new study.

Discussions about reducing greenhouse gas emissions usually concentrate on cleaner ways of generating energy: that's because they promise that we can lower emissions without having to change our energy-hungry ways. But whereas new generation techniques take years to come on stream, efficiency can be improved today, with existing technologies and know-how.

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.

Finally, E-Paper Screens Made Of Real Paper! -- Popular Mechanics

In December, electrical engineers at the University of Cincinnati reinvented the wheel. By applying electric fields to nonglass materials, they discovered they could make an e-paper display screen using the unlikeliest of materials—paper.

This discovery has big implications for the future of the screen: Making a display out of regular old paper could maximize affordability, decrease environmental impact and also save space, since a paper screen has the potential to roll up and pull out. So is it time to throw out our retro flatscreens and make room for paper television? Not just yet.

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.

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.

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 study, published in the journal Science, used Hawaii's twin 10-metre Keck telescopes to scan 166 sun-like stars within 80 million light years, or about 757 trillion kilometres.

From Popular Science:

The new round of experiments aim to find out what matter looked like at the dawn of time.

Smashing protons at high energies is fun and all, but researchers at the Large Hadron Collider are taking a vacation from their day-to-day proton smashing, and taking a trip back to the very origins of the universe. Starting this month and continuing for four weeks, the LHC will accelerate and then collide lead ions – that is, entire atomic nuclei – to create a series of miniature Big Bangs that will let researchers take a look at the quark-gluon plasma that existed just a fraction of a second after the universe was born.

‘Invisible’ Material Can Now Fool Your Eyes



From The Danger Room/Wired:

Don’t start picking out the pattern of your cloak, yet. But invisibility just became a whole lot more likely.

Tech journalists and military dreamers have talked about real-life invisibility cloaks for a while, and with good reason. With their specialized structures, so-called “metamaterials” can bend light around objects, making ‘em disappear.

Eye Implant Allows The Blind To See Again



From The Telegraph:

An eye implant which has returned partial sight to three blind patients has been developed by scientists.

The device is being hailed as an "unprecedented advance" in visual aids, and could revolutionise the lives of 200,000 people who suffer from the degenerative eye condition retinitis pigmentosa.

The hereditary disease means that light receptors in the eye cease to function, impairing vision.

New York To Sydney In Just 2hrs 30mins: Nasa To Develop 'Hypersonic' Passenger Jets That Travel At Five Times The Speed Of Sound

From The Daily Mail:

NASA is planning to build hypersonic jets that will fly through the Earth’s atmosphere and slash flight times around the world to a few hours at most.

The US space agency wants to manufacture a craft that would travel at five times the speed of sound and bring in a new age of aircraft akin to a turbo-charged Concorde.

Travelling at such speed would reduce the flight time from New York to Sydney to around two-and-a-half hours, from the 21 hours it is now.

From New Scientist:

Atoms called positronium inexplicably scatter off gas particles as if they were lone electrons, even though they contain an anti-electron as well. The finding hints that engineers could use the well-known scattering properties of electrons as a rule of thumb in designing future medical scanners that employ positronium. It could also help interpret puzzling astronomical observations.

Space Shuttle Discovery: Launch Delayed To Nov. 30



From ABC News:

Final Flight for Discovery but Ship 'Not Going Out Easy'.


If the space shuttle Discovery had launched on schedule, she would now be in orbit, docked with the International Space Station, her six astronauts joining the six currently on board the station to unload 22,000 earth pounds of equipment.

But as has often happened in 30 years of shuttle flights, Discovery still sits on launch pad 39A at the Kennedy Space Center here in Florida, waiting as mission managers worked their way through a minor helium leak, a minor electrical problem and Florida's famously unpreditable weather.
