Despite the sophistication and range of contemporary microscopy techniques, many important biological phenomena still elude the precision of even the most sensitive tools. The need for refined imaging methods for fundamental research and biomedical …
A simple technique to make a common virus-killing material significantly more effective is a breakthrough from the Rice University labs of Andrew Barron and Qilin Li.
Rather than trying to turn the process into profit, the researchers have put it …
UCSF researchers have identified an existing medication that restores key elements of the immune system that, when out of balance, lead to a steady decline in immunity and health as people age.
The team found that extremely low doses of the dr…
A variant of last year’s pandemic influenza linked to fatal cases carried a mutation that enabled it to infect a different subset of cells lining the airway, according to new research. The study, due to be published next week in the Journal of Virol…
Researchers have discovered one way in which the human immunodeficiency virus (HIV) wins its cat-and-mouse game with the body’s immune system. The study, published in the March 20, 2003, issue of the journal Nature, shows that HIV-1, a common strain of the virus that causes AIDS, uses a strategy not seen before in other viruses to escape attack by antibodies, one of the immune system’s prime weapons against invading viruses and bacteria.
In a discovery that is likely to impact fields as diverse as medicine and nanomanufacture, researchers have determined how nature arranges charged particles in a thin layer around a sphere. The leap forward in understanding this theoretical problem may help reveal structural chinks in the outer armor of viruses and bacteria (revealing potential drug targets) and guide engineers designing new molecules. On a flat surface, particles that repel each other will arrange themselves to create a stable energy state, eventually settling at vertices within a lattice of identical triangles much like billiard balls at the start of a game.
