Molecular event mapping opens door to more tests "in silico"

Scientists report a new method for establishing whether chemical compounds are safe for human use without "in vivo" testing, based on so-called "molecular initiating events" at the boundary between chemistry and biology.

Lake Tahoe clarity improves, outlook not so clear

While clarity improved at Lake Tahoe for a second straight year in 2012, long-term trends show that climate change is impacting the Lake Tahoe Basin with drier years, less precipitation, higher lake temperatures and projected ...

Solving electron transfer

EPFL scientists have shown how a solvent can interfere with electron transfer by using unprecedented time resolution in ultrafast fluorescence spectroscopy.

Drug side effects examined

Yellow vision, pseudo-pulmonary obstruction, involuntary body movements, respiratory paralysis. These are some of the 1,600 known side effects (SEs) produced by drugs. Adverse effects are one of the main causes of hospital ...

Best image yet of atoms moving in real time produced (w/ video)

Call it the ultimate nature documentary. Scientists at the University of Toronto have recorded atomic motions in real time, offering a glimpse into the very essence of chemistry and biology at the atomic level. Their recording ...

Osmosis: Everything you know about it is (probably) wrong

Osmosis – the flow of a solvent across a semipermeable membrane from a region of lower to higher solute concentration – is a well-developed concept in physics and biophysics. The problem is that, even though the concept ...

Team develops psoriasis drug

Ben-Gurion University of the Negev (BGU) researchers, in collaboration with Teva Pharmaceutical Industries Ltd., have developed a promising drug candidate to treat psoriasis. The finding was reported in a new paper published ...
