Biologically inspired sensors can augment sonar, vision system in submarines

...urroundings, Liu said. "Although biology remains far superior to human engineering, having a man-made parallel of the biological system allows us to learn much about both basic science and engineering," Liu said. "To actively learn from biology at the molecular, cellular, tissue and organism level is s...

Cracking open the black box of autoimmune disease

...genes, we can now look for possible therapies with far greater precision." The immune system is often described as a kind of military unit, a defense network that guards the body from invaders. Seen in this way, a group of white blood cells called T cells are the frontline soldiers of immune defense, ...

Over a century after disappearing, wild elk return to Ontario

... success to date, Rosatte asserts that the work is far from over. "Our challenge for the future will be to develop accurate methods to estimate elk numbers and locations, so that elk can be managed in a sustainable manner, and in a way that minimizes conflicts between elk and humans." ...

New hereditary breast cancer gene discovered

...g for new hereditary breast cancer genes, but thus far few have been found. "Our findings are extremely important, providing new knowledge of hereditary cancer genes and how they can cause breast cancer. The discovery also makes it possible to uncover breast cancer in women who have a predisposition ...

Multiple malaria infection inhibits spread of parasite

...on and age dependent. Children were found to be by far the most important source of malaria transmission in the area. In the village Koundou, the number of infectious bites was about five times as high as in the capital. There previous research had revealed 177 infectious bites. Test The existin...

Study finds mercury prevalent in many western fish

...searchers say, including coal power plants from as far away as China, the burning of heavy oils and other fossil fuels, and even forest fires. In the survey, the researchers did find 13 fish from eight different sites that had very high mercury concentrations ?levels of 1.0 microgram or higher ?likely...

Florida Tech explores microalgae for biofuel

...lgae. Successful microalgae production for fuel so far is in small-scale cultivation. Lin will cultivate the energy source at the university’s Vero Beach Marine Laboratory. His work is to test conditions that will optimize large-volume cultures of microalgae in outdoor, open settings. Cultures in outdoo...

Common mechanisms for viral DNA replication

...e double-membrane nucleus. However, the process is far easier to study in the much simpler virus. In simian virus 40 (SV40), the large T-antigen protein (T-ag) is responsible for recognizing DNA sequences required to start replication, called the origin of replication. SV40 T-ag can also cause DNA to mel...

Satellites shed light on global warming

...at although they were theorised to have existed as far back as the 1930s, it was not until the advent of the satellite-borne radar altimeter that oceanographers were able to offer proof of their existence by mapping the sea surface height and seeing them move by following the measurements of the surface....

Furthermore, they found that miRNA expression patterns changed during gamete differentiation, suggesting a possible role in regulating sexual reproduction. The discovery of miRN...

CSIRO imagery shows Outer Great Barrier Reef at risk from river plumes

...conventional patterns and travelling quite fast as far as 65 to 130km, to the outer reef and, in some instances, travelling along the outer reef and re-entering the reef. The plumes are the result of heavy rainfalls in northern QLD around late January to early February 2007, with the resulting flood ...

Major link in brain-obesity puzzle found

...cal School researchers report. And although it’s far too early to say how this protein could be useful in new strategies to fight the world’s epidemic of obesity, the finding gives scientists an important system to target in future research and the development of anti-obesity medications.

"Chromosomal microarray analysis is far better at picking up these abnormalities than other common methods," said Dr. Arthur Beaudet, chair of the department of molecular and human genetics at BCM and an author of the paper. "It allows us to identify the source of abnormalities in many cas...

New UD technology removes viruses from drinking water

MIT bioengineer advances survival, promise of adult stem cells

...ersion of the factor did not protect cells." So far all of the experiments have been done in vitro, or outside the body, but the researchers are currently planning studies in animals. Griffith, who does not work with human embryonic stem cells, believes that adult stem cells offer promising therap...
