Scientists find odd twist in slow 'earthquakes': Tremor running backwards

2011-05-23
Earthquake scientists trying to unravel the mysteries of an unfelt, weeks-long seismic phenomenon called episodic tremor and slip have discovered a strange twist. The tremor can suddenly reverse direction and travel back through areas of the fault that it had ruptured in preceding days, and do so 20 to 40 times faster than the original fault rupture. "Regular tremor and slip goes through an area fairly slowly, breaking it. Then once it's broken and weakened an area of the fault, it can propagate back across that area much faster," said Heidi Houston, a University of ...

Scientists find new drug target in breast cancer

2011-05-23
Researchers have identified a new protein involved in the development of drug resistance in breast cancer which could be a target for new treatments, they report today in the journal Nature Medicine. In a mouse model of breast cancer, blocking production of the protein using genetic techniques caused tumours to shrink. The scientists are now looking for new drugs which could achieve a similar effect. Breast cancer is the most common cancer in the UK, affecting about 46,000 women each year. More than two thirds of breast tumours contain oestrogen receptors, meaning that ...

Gulf currents primed bacteria to degrade oil spill

2011-05-23
A new computer model of the Gulf of Mexico in the period after the oil spill provides insights into how underwater currents may have primed marine microorganisms to degrade the oil. "It is called dynamic auto-inoculation. Parcels of water move over the ruptured well, picking up hydrocarbons. When these parcels come back around and cross back over the well, the bacteria have already been activated, are more abundant than before, and degrade hydrocarbons far more quickly," says David Valentine of the University of California, Santa Barbara, speaking today at the 111th ...

The dance of the cells: A minuet or a mosh?

2011-05-23
Boston, MA – The physical forces that guide how cells migrate—how they manage to get from place to place in a coordinated fashion inside the living body— are poorly understood. Scientists at the Harvard School of Public Health (HSPH) and the Institute for Bioengineering of Catalonia (IBEC) have, for the first time, devised a way to measure these forces during collective cellular migration. Their surprising conclusion is that the cells fight it out, each pushing and pulling on its neighbors in a chaotic dance, yet together moving cooperatively toward their intended direction. The ...
