Multinational research: protecting ecology means understanding people, too
...rcent of its environmental specialists. Its good timing for students as well, they say. Students are hungry for this kind of program, Stronza said. They will address issues of invasive species, declining range size and diminishing species populations, poverty and social conflict, over-exploitation of re...Census of Marine Life historians detail collapse of bluefin tuna population off northern Europe

Companion research says the tags recorded remarkable behaviour shifts among tuna breeding in this region, including shallower, more oscillatory diving and a tendency to stay near the surface. Lingering in......ool. In strategies to quell the anthrax microbe, timing is everything. During most of its life cycle, the organism has formidable defenses. These make it a challenge for scientists to find a prime moment when future drugs, without the digestive-tract side effects and other drawbacks of those used now, can...New study demonstrates important role of glia in circadian timing

... lab are looking into the factors that control the timing and position of cell division in B. subtilis. B. subtilis serves as the model system for a large family of bacteria that includes the causative agents of several important diseases, including anthrax and botulism. By learning how these simple organis...Ability to listen to 2 things at once is largely inherited, says twin study

... virulence may shed light on the future course and timing of the evolution of HIV. The new research also challenges the idea that one ancient SIV was transmitted vertically, down through time, and evolved into many SIVs as its original host diverged into many different species. Wertheim and Worobey su...MIT, BU team builds viruses to combat harmful 'biofilms'
...etic biology also makes it possible to control the timing of when a gene is expressed in an organism. For instance, Lu inserted the DspB genes into a precise location in the T7 genome so that the phage would strongly express it during infection rather than before or after. Such control was possible because ...Loss of hemlocks will affect water dynamics in southern Appalachian forests

...s seedlings show a spurt of growth once a day. The timing of that growth spurt is controlled by both the plant's internal clock and by exposure to light, acting on two genes called PIF 4 and PIF 5.

...ts increasingly suspect that it may play a role in timing the cell division process. Commonly, cancer cells have entirely lost their cilia, and this absence may help explain why tumors fail to respond properly to environmental cues that cause normal cells to stop growing. Hence, the discovery that too much......overed and call into question hypotheses about the timing and pattern of penguin evolution and expansion.
