Mitochondrial DNA sequencing tool updated

...say their full-sequence chip will be a key tool in accelerating research on mitochondrial DNA, a growing area of scientific interest. This interest stems from data that suggests natural sequence variations and/or mutations in each person's mitochondrial DNA could be biologically informative in fields as diverse ...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...nal Laboratory's Advanced Photon Source, where the accelerating voltage ranges from one to 20 keV, says Brinker. Genetic modification done cheap It is noteworthy that the entrapped cells easily absorb other nano-components inserted at the cellular interface. Because of this, the cell can internalize new DNA (...

Novel therapy combinations gain ground in treating hepatitis

...is A or B, use of acetaminophen may play a role in accelerating liver failure, ordinarily a rare complication of viral hepatitis. Serum samples from 72 patients with proven hepatitis A or B that had progressed to liver failure were tested for APAP adducts, which are the toxic byproducts of acetaminophen liver d...

Researchers appeal for new regulations to save coral reefs from live fish trade

...n live reef fish. They have also demonstrated the accelerating pace of the boom and bust pattern of exploitation,...kets. The trade has spread from Hong Kong at an accelerating pace, starting at 100 km per year from its coast in the 1970s, to reach over 400 km per year in the ...

The brain, traffic and nano-circuits -- e-Science takes on major challenges

...as street and building design, vehicle braking and accelerating patterns, individual traveller decisions and local weather conditions affect the concentration of pollutants that individuals are exposed to as they move around. The £3.5m PMESG (Pervasive Mobile Environmental Sensor Grids) project, led by Professor...

By 2048 all current fish, seafood species projected to collapse

Marine species loss is accelerating and threatening human well-being, according to a report published in the 3 November issue of the journal Science published by AAAS, the nonprofit science society. "Species have been disappearing from ocean ecosystems and this trend has recently be...

Satellites shed light on global warming

... and Envisat satellites. The retreat has been accelerating since 1992 and has culminated in two collapse events: Larsen-A in January 1995 and Larsen-B in March 2002. Envisat captured the disintegration of the 200-metre-thick Larsen-B Ice Shelf, which researchers estimate had been stable since the last ice ag...

New research may overturn conventional wisdom on drug-resistant tuberculosis

...thors said, "Our findings highlight the urgency of accelerating efforts to interrupt the transmission of drug-resistant tuberculosis." The research shows improved methods of preventing TB transmission may be needed in the very facilities and communities where TB patients are treated. Fast Facts ...

Researchers shed light on mechanism of action used by anti-cancer drug

...s, increasing levels of protein chaperones, and by accelerating protein degradation. However, according to Grant, when ER stress exceeds a certain threshold, the ER stress response is converted from an adaptive to a pro-death response. The team observed that exposure of cells to sorafenib resulted in the pro...
