A seaweed considered a threat to the healthy growth of coral reefs in Hawaii may possess the ability to produce substances that could one day treat human diseases, a new study led by scientists at Scripps Institution of Oceanography at University of California, San Diego has revealed.

In a new study, investigators from the University of California, Los Angeles describe how they synthesized polymers to attach to proteins in order to stabilize them during shipping, storage, and other activities. The study findings suggest that these polymers could be useful in stabilizing protein formulations.

Quantum physics and plant biology seem like two branches of science that could not be more different, but surprisingly they may in fact be intimately tied. Researchers at Argonne National Laboratory and the Notre Dame Radiation Laboratory at the University of Notre Dame used ultrafast spectroscopy to see what happens at the subatomic level during the very first stage of photosynthesis.

University
of Iowa neuroscientist John Wemmie is interested in the effect of acid
in the brain. His studies using new magnetic resonance imaging
techniques suggest that increased acidity or low pH, in the brain is
linked to panic disorders, anxiety, and depression. But his work also
suggests that changes in acidity are important for normal brain activity
too.

Plants
rely on photoreceptors to activate internal chemical processes like
germination and leaf growth. Theorizing that the light-absorbing
component of the photoreceptor may be replaced by a chemically similar
synthetic substance, scientist have for the first time shown that full
growth of plants is possible in the complete absence of light.

Researchers at the Joint BioEnergy Institute have identified a tropical rainforest microbe that can endure relatively high concentrations of an ionic liquid used to dissolve cellulosic biomass for the production of advanced biofuels. They've also determined how the microbe accomplishes this, a discovery that holds broad implications beyond biofuels.

A
pill that has long been used to treat HIV has moved one step closer to
becoming the first drug approved to prevent healthy people from becoming
infected with the virus that causes AIDS. The Food and Drug
Administration said Tuesday that Gilead Sciences' Truvada appears to be
safe and effective for HIV prevention.

One
exhale and a new device from researchers at Stony Brook University in
New York could screen for anything from diabetes to lung cancer. Based
on a sensor chip built from electrospun nanowires that can detect minute
amounts of chemical compounds, the device has yet to reach clinical
trials. But its inventors anticipate the device to someday cost only
$20.

When
the DNA double helix breaks, the broken end goes searching for the
similar sequence and uses that as a template for repair. Using a new
dual-molecule technique, a research group in the Netherlands has
found out how the DNA molecule is able to perform this search and
recognition process in such an efficient way.

Four
months ago the U.S. government sought to block publication of two
studies about how scientists created an easily spread form of bird flu.
Now a revised version of one paper is seeing the light of day with the
government's blessing. The second paper, which is more controversial
because it involves what appears to be a more dangerous virus, is
expected to be published later.
