Plans to be discussed at the forthcoming UN climate conference in Copenhagen to cut deforestation in developing countries could save some species from extinction but inadvertently increase the risk to others, scientists believe.
A team of eleven of the world`s top tropical forest scientists, coordinated by the University of Leeds, warn that while cutting clearance of [...]

Structural biologists at the University of Pittsburgh School of Medicine have described the architecture of the complex of protein units that make up the coat surrounding the HIV genome and identified in it a "seam" of functional importance that previously went unrecognized. Those findings, reported today in Cell, could point the way to new treatments [...]

Novel nanomaterials developed at Rensselaer Polytechnic Institute are scheduled to blast off into orbit on November 16 aboard Space Shuttle Atlantis.
The project, funded by the U.S. Air Force Multi University Research Initiative (MURI), seeks to test the performance of the new nanocomposites in orbit. Space Shuttle Atlantis will carry the samples to the International Space [...]

Short-term memory may depend in a surprising way on the ability of newly formed neurons to erase older connections. That`s the conclusion of a report in the November 13th issue of the journal Cell, a Cell Press publication, that provides some of the first evidence in mice and rats that new neurons sprouted in the [...]

Scientists at the University of Liverpool are constructing highly sensitive detectors as part of an international project to understand the elements that make up the universe.
The detectors will become part of the Advanced Gamma Tracking Array (AGATA) experiment, currently based in Italy, which aims to create a `fingerprint` of the inside of the atomic nucleus [...]

A compound in coffee has been found to be estrogenic in studies by Texas AgriLife Research scientists. Though the studies have not been conducted to determine recommended consumption amounts, scientists say the compound, called trigonelline or "trig," may be a factor in estrogen-dependent breast cancer but beneficial against colon cancer development.

Orchids are famous for their deceptions. Most of those with nothing of value to offer their pollinators lure them instead with the scents of more rewarding flowers or potential mates. Now, a report published online on August 6th in Current Biology, a Cell Press publication, reveals for the first time that a species of orchid, [...]

Researchers at Uppsala University, in collaboration with colleagues in Sweden and abroad, have identified an entirely new mechanism by which a specific protein in the body inhibits formation of new blood vessels. Inhibiting the formation of new blood vessels is an important aspect of, for example, cancer treatment. The study is published in the November [...]

Got food poisoning? The cause might be bacterial spores, en extremely hardy survival form of bacteria, a nightmare for health care and the food industry and an enigma for scientists. Spore-forming bacteria, present almost everywhere in our environment, can also cause serious infectious diseases, such as tetanus, anthrax, and botulism.
Now researchers from Lund University in [...]
