The Orange Goo That Could Save Your Laptop 285

Barence writes "A British company has patented what can only be described as an orange goo that could save your laptop or iPod after a nasty fall. The amazing material is soft and malleable like putty, but the substance becomes solid instantly after impact. You can punch your fist into a ball of the material sitting on a desk and not feel a thing, according to the staff at PC Pro who have been testing the material, called 3do. It's being used by the military, the US downhill ski team, and motorcycle clothing manufacturers to provide impact protection in the event of a crash. However, it's also appearing in protective cases for laptops and MP3 players."

Painting The World's Roofs White Could Slow Climate Change 712

Hugh Pickens writes "Dr. Steven Chu, the Nobel prize-winning physicist appointed by President Obama as Energy Secretary, wants to paint the world white. Chu said at the opening of the St James's Palace Nobel Laureate Symposium that by lightening paved surfaces and roofs to the color of cement, it would be possible to cut carbon emissions by as much as taking all the world's cars off the roads for 11 years. Pale surfaces reflect up to 80 percent of the sunlight that falls on them, compared with about 20 percent for dark ones, which is why roofs and walls in hot countries are often whitewashed."

How to Deal With an Aging Brain? 684

An anonymous reader writes "I'm sure this is something all older Slashdotters are aware of: as I get older my once-sharp brain is, well, getting worse. In particular, I'm not able to remember things as well as I once did. As a geek my capacity in this area was always what defined me as a geek. Nowadays things seem to go in OK, but then leak out. A few weeks later I've mostly forgotten. So, I ask Slashdot: how do you cope with your mind getting older? What's your trick? Fish-oil? Brain Training on the DS? Exercise? Or just trying harder to remember things?"

Why You Can't Buy a Naked PC 367

ZDOne writes "A piece up on ZDNet looks at the issue of naked PCs. ZDNet UK phoned around all the major PC vendors and not one of them would sell a machine without Windows on it. IT professionals are being forced to adopt Microsoft's operating systems — even if they tell their PC supplier they want a system free of Microsoft software. On the other hand, even if it's almost impossible to buy a PC without an operating system installed, companies like Dell and HP are now committed to supporting Linux as well. 'Murray believes there is a market for Linux in the UK but is also aware of the issues facing any large supplier who wants to make Linux boxes available. "It means diverting production lines and that is a lot of money and so we have to prove the business case," he said. However, he made it clear that he is enthusiastic about the idea and wants to make it work. "We just have to show it is worthwhile," he said.'"
