McMaster study unveils lifeline for 'antibiotic of last resort'
Most antibiotics work by inhibiting an enzyme but vancomycin binds to cell wall building blocks, causing a weakness in the structure of the cell wall so the cell bursts and dies.

MIT researchers harness viruses to split water
A team of MIT researchers has found a novel way to mimic the process by which plants use the power of sunlight to split water and make chemical fuel to power their growth.

Biological link between stress, anxiety and depression identified for the first time
Scientists at the University of Western Ontario have discovered the biological link between stress, anxiety and depression.

BSSA tip sheet for April 2010
The following articles will appear in the April issue of the Bulletin of the Seismological Society of America.

Mutations directly identifiable in active genes
Researchers at Uppsala University have developed a new method for identifying genetic variation, including mutations, in active genes.

Faulty cleanup process may be key event in Huntington's disease
In a step towards a possible treatment for Huntington's disease, scientists at Albert Einstein College of Medicine of Yeshiva University have shown for the first time that the accumulation of a mutated protein may explain damaging cellular behavior in Huntington's disease.

Maternal deaths fall worldwide from a half-million annually to less that 350,000
The number of women dying from pregnancy-related deaths has dropped by more than 35 percent in the past 30 years.

Under new leadership, Kavli Institute at Cornell evolves from a think tank to a proving ground
Looking to push the boundaries of nanoscience, the Kavli Institute at Cornell for Nanoscale Science is no longer a think tank for new ideas, but a proving ground to aggressively push the limits of nanotechnology.

Key protein aids in DNA repair
In a paper published in the journal Nature, researchers at the University of North Carolina at Chapel Hill's Lineberger Comprehensive Cancer Center have shown that a particular protein -- called Ku -- is particularly adept at healing damaged strands of DNA.

The assembly of protein strands into fibrils
Researchers at ETH Zurich, EPF Lausanne and at the University of Fribourg have evidenced a basic general mechanism describing how filamentous proteins assemble into ribbon like structures, the so-called Amyloid fibrils.

Hormone sensitivity of breast stem cells presents drug target
Researchers at the Walter and Eliza Hall Institute have discovered that breast stem cells are exquisitely sensitive to the female hormones estrogen and progesterone, a finding that opens the way for the development of new preventions and treatments for breast cancer.

British scientific expedition discovers world's deepest known undersea volcanic vents
A British scientific expedition has discovered the world's deepest undersea volcanic vents, known as

MIT: New cell measurement system
Using a sensor that weighs cells with unprecedented precision, MIT and Harvard researchers have measured the rate at which single cells accumulate mass -- a feat that could shed light on how cells control their growth and why those controls fail in cancer cells.
