We should be praying for wisdom for politicians and scientists as we make decisions that have worldwide effect. Besides commodities traders driving up the cost of gas, which also affects the price of food and everything else, we now have to worry about cooling.

"For the second time in little over a year, it looks as though the world may be heading for a serious food crisis, thanks to our old friend "climate change". In many parts of the world recently the weather has not been too brilliant for farmers. After a fearsomely cold winter, June brought heavy snowfall across large parts of western Canada and the northern states of the American Midwest. In Manitoba last week, it was -4ºC. North Dakota had its first June snow for 60 years.

There was midsummer snow not just in Norway and the Cairngorms, but even in Saudi Arabia. At least in the southern hemisphere it is winter, but snowfalls in New Zealand and Australia have been abnormal. There have been frosts in Brazil, elsewhere in South America they have had prolonged droughts, while in China they have had to cope with abnormal rain and freak hailstorms, which in one province killed 20 people.

None of this has given much cheer to farmers. In Canada and northern America summer planting of corn and soybeans has been way behind schedule, with the prospect of reduced yields and lower quality. Grain stocks are predicted to be down 15 per cent next year. US reserves of soya – used in animal feed and in many processed foods – are expected to fall to a 32-year low.

On March 3, The New York Times Magazine created a major flap in the climate-change community by running a cover story on the theoretical physicist Freeman Dyson that focused largely on his views of human-induced global warming.

Basically, he doesn’t buy it. The climate models used to forecast what will happen as we continue to pump CO2 into the atmosphere are unreliable, Dyson claims, and so, therefore, are the projections. In an interview with Yale Environment 360, his first since the Times article appeared, Dyson contends that since carbon dioxide is good for plants, a warmer planet could be a very good thing. And if CO2 does get to be a problem, Dyson believes we can just do some genetic engineering to create a new species of super-tree that can suck up the excess.

These sorts of arguments are advanced routinely by climate-change skeptics, and dismissed just as routinely by those who work in the field as clueless at best and deliberately misleading at worst. Dyson is harder to dismiss, though, in part because of his brilliance. He’s on the faculty at the Institute for Advanced Study, where as a young physicist he hobnobbed with Albert Einstein. When Julian Schwinger, Sin-Itiro Tomonaga and Richard Feynman shared the 1965 Nobel Prize in physics for quantum electrodynamics, Dyson was widely acknowledged to be almost equally deserving — but the Nobel Committee only gives out three prizes for a given discovery.

A couple years back I was working on a video game engine and I had planned on implementing features like this. The project got canned but I'm glad to see that Nvidia is making something like this available to all developers. I was just watching the Red Faction: Guerrilla demos and it looks fun going around smashing buildings!

Here's something that people with poor or no vision will be excited about: three patients had their sight restored in less than a month by contact lenses cultured with stem cells. Note that this had nothing to do with Embryonic Stem Cells but Adult Stem Cells (for more on this topic see "Embryonic Stem Cell Research Unnecessary").

All three patients were blind in one eye. The researchers extracted stem cells from their working eyes, cultured them in contact lenses for 10 days, and gave them to the patients. Within 10 to 14 days of use, the stem cells began recolonizing and repairing the cornea.

RICHLAND, Wash. – A transparent thin film barrier used to protect flat panel TVs from moisture could become the basis for flexible solar panels that would be installed on roofs like shingles.

The flexible rooftop solar panels - called building-integrated photovoltaics, or BIPVs - could replace today's boxy solar panels that are made with rigid glass or silicon and mounted on thick metal frames. The flexible solar shingles would be less expensive to install than current panels and made to last 25 years.
