HIV-1 Inhibitor Found In Deer Tick Saliva |

The HIV-1 virus cripples the human immune system by targeting white
blood cells called T cells that form the body’s first line of defense
in fighting infections. A recent study by researchers from the
University of Massachusetts Amherst shows that a protein called Salp15, found in the
saliva of deer ticks, prevents the HIV-1 virus from attaching to the
surface of T cells, which is the critical first step in the virus’
attack strategy. Results were published in the February 2008 issue of Biochemical and Biophysical Research Communications. The abstract can be found here.

National Science Foundation (NSF) Director Arden L. Bement Jr. has
presented the agency's proposed $6.85 billion budget for fiscal year
(FY) 2009, a 13 percent increase over its actual FY 2008 budget. The
additional $822.10 million would increase funding for agency programs
that advance the frontiers of research and education in science and
engineering.Read more here.

Silica Smart Bombs Deliver Knock-Out to Bacteria |
|
Wednesday, 27 February 2008 |
|
Bacteria mutate for a living, evading antibiotic drugs while killing
tens of thousands of people in the United States each year. But as
concern about drug-resistant bacteria grows, one novel approach under
way at the University of North Carolina at Chapel Hill seeks to thwart
the bug without a drug by taking a cue from nature. Mark
Schoenfisch and his lab of analytical chemists at UNC have created
nano-scale scaffolds made of silica and loaded with nitric oxide (NO) –
an important molecule in mammals that plays a role in regulating blood
pressure, neurotransmission and fighting bacterial infections, among
other vital functions. Read more here.
