World's top theoretical physicists converge to consider 'future of physics'
... Accordingly, the auditorium is much wider than long
with three rows of fixed seats in a semicircle facing a wide expanse of blackboard. Everybody can see everybody, and physicists seated in the front row can dash to the blackboard to illustrate or work out their points. Three separate, motorized dro...
Emory chemists develop bacteria that may help decaffeinate coffee

as theophylline is present because theophylline turns on the production of the "cat" protein. Gallivan says not to expect good-tasting, naturally decaffeinated coffee anytime soon. "We're still at the earliest stages of this work. There are many hur...

...called E3 ubiquitin ligases. These ligases place a long
tail of ubiquitin molecules on proteins, which are then slated for degradation and recycling. The degradation signaling process is set in motion when a protein is "misfolded" and cannot function properly. Degradation also occurs when proteins of inv...

Study using robotic microscope shows how mutant Huntington's protein affects neurons
...The role of inclusion bodies in these diseases has long
been controversial. Some studies suggest that they may be a critical part of the disease process, while others indicate that they may help protect the cells from toxic proteins or that they are merely bystanders in the disease process. One prob...
Where in the brain decisions are made
While neurobiologists have long
suspected that certain regions of the brain are specifically involved in making decisions, the challenge has been to develop rigorous laboratory behavioral experiments that could pinpoint those areas. Now, Paul Glimcher and colleague Michael Dorris h...
