If you read the rest of this newsletter, you might have noticed the theme of carbon footprints and "greening" the supply chain. It used to be that you could concentrate on making the supply chain more efficient without giving too much thought to energy efficiency or global warming. Are those days go

A world-renowned team of experts in biomechanics and physiology from six universities, led by Professor Hugh Herr of the Massachusetts Institute of Technology?s Media Lab, refute scientific claims that the prostheses worn by Oscar Pistorius, a 21-year-old South African bilateral amputee track athlete, provide him with an unfair advantage in the 400-meter race.

Small molecule can take apart Alzheimer's disease
protein fibers

post from Science Blog - Send lawyers, guns and money on 16 May 2008 10:18:14 AM. © Science Blog - Send lawyers, guns and money

Researchers from the University of Pennsylvania School of Medicine have shown, in unprecedented detail, how a small molecule is able to selectively take apart abnormally folded protein fibers connected to Alzheimer's disease and prion diseases. The findings appear online this week in the Proceedings of the National Academy of Sciences. Finding a way to dismantle misfolded proteins has implications for new treatments for a host of neurodegenerative diseases.

Black Holes Don't Trap Information Forever

From Slashdot: New calculations suggest that black holes are not a one-way street. Anything that falls into them may eventually come out. The findings lend important support to quantum gravity, but fly in the face of Einsteinian relativity. They also support Stephen Hawking's reluc

This is a fun little experiment with water that was supercooled to -21C (-6F). The supercooled water is poured into a bowl. It pours out as a liquid and turns to slush, forming ropelike peaks [1:07].

Biosensor for measuring stress in cells

post from Science Blog - Send lawyers, guns and money on 16 May 2008 09:53:12 AM. © Science Blog - Send lawyers, guns and money

Cancer, nervous system disorders such as Parkinson?s disease, cardiovascular disorders and old age have one thing in common: Both in afflicted tissue and in aging cells, scientists have observed oxidative changes in important biomolecules. These are caused by reactive oxygen molecules, including the notorious ?free radicals? that are formed as a by-product of cellular respiration and attack cellular proteins, nucleic and fatty acids.
