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 [...]

A team of scientists at Cold Spring Harbor Laboratory (CSHL) reports on Thursday their success in solving the molecular structure of a key portion of a cellular receptor implicated in Alzheimer`s, Parkinson`s, and other serious illnesses.
Assistant Professor Hiro Furukawa, Ph.D., and colleagues at CSHL, in cooperation with the National Synchrotron Light Source at Brookhaven National [...]

Men consistently outperform women on spatial tasks, including mental rotation, which is the ability to identify how a 3-D object would appear if rotated in space. Now, a University of Iowa study shows a connection between this sex-linked ability and the structure of the parietal lobe, the brain region that controls this type of skill.
The [...]

Scientists at the Swedish medical university Karolinska Institutet have determined the first 3D structure of ZP3, a protein essential for the interaction between the mammalian egg coat and sperm. The findings, presented in Nature, gives a first glimpse into the molecular architecture of animal egg coats, with important implications for the future of human reproductive [...]

In addition to its strong associations with hypertension, cardiovascular disease, and diabetes, pediatric obesity may induce alterations in thyroid function and structure, according to a new study.
Thyroid hormones drive metabolism, however demonstration of a direct or strong correlation of obesity with deficient thyroid function has been controversial, and previous studies provide conflicting conclusions. While some [...]

There is no longer any shadow of a doubt about the impact of global warming on coral reefs. A rise of a few degrees in sea surface temperature induces the expulsion of essential microscopic algae which live in symbiosis with the coral. This process is the cause of coral bleaching and is well known to [...]

A team of Johns Hopkins University neuroscientists has discovered patterns of brain activity that may underlie our remarkable ability to see and understand the three-dimensional structure of objects.
Computers can beat us at math and chess, but humans are the experts at object vision. (That`s why some Web sites use object recognition tasks as part of [...]

Repairing breaks in the two strands of the DNA double helix is critical for avoiding cancer. In humans and other organisms, a molecular machine called the MRN complex is responsible for finding and signaling double-strand breaks (DSBs), then launching the error-free method of DNA repair called homologous recombination.
In a new article John Tainer of the [...]
