The most effective way to prevent the deliberate misuse of biological select agents and toxins -- agents housed in laboratories across the US considered to potentially pose a threat to human health -- is to instill a culture of trust and responsibility in the laboratory, says a new report. Focusing on the laboratory environment will be critical for identifying and reducing concerns about facilities or personnel.

Scientists have identified a novel enzyme responsible for the formation of suberin -- the woody, waxy, cell-wall substance found in cork. Adjusting the permeability of plant tissues by genetically manipulating the expression of this enzyme could lead to easier agricultural production of crops used for biofuels.

Investigators from the US Air Force Academy and US Air Force School of Aerospace Medicine Epidemiology Consult Service capitalized on a unique opportunity to gain valuable insights about the natural behavior of the nH1N1 virus, including shedding patterns, during a recent large-scale outbreak at the US Air Force Academy.

Glutamate is to the brain like coffee is to our bodies. A cup of Joe in the morning can wake us, but overloading on caffeine causes the stimulant to work against us.

Global warming in the next century could cause a significant increase in the productivity of high-elevation forests of the Pacific Northwest, a new study suggests. However, forests at lower elevations -- which in recent years have accounted for more than 80 percent of the region's timber harvest -- could face a decline in growth.

Jerusalem's geology has been crucial in molding it into one of the most religiously important cities on the planet, according to a new study.

Seismologists have found a new way to piece together the history of hurricanes in the North Atlantic -- by looking back through records of the planet's seismic noise. It's an entirely new way to tap into the rich trove of seismic records, and the strategy might help establish a link between global warming and the frequency or intensity of hurricanes.
