Just as homes have smoke detectors, cells have an enzyme that responds to a buildup of fatty acids by triggering the production of a key molecule in the biochemical pathway that breaks down these fatty acids, according to investigators at St. Jude Children's Research Hospital. This breakdown of fatty acids, in turn, provides the cell energy while reducing the chance that excess fatty acids will accumulate.

When the next big earthquake hits a region like San Francisco, Natural Sciences and Engineering Research Council (NSERC) grantee Kristy Tiampo wants to ensure that communities will not only be able to evacuate, but also rebuild.

This is why Tiampo, the NSERC and Benfield/ICLR Industrial Research Chair in Earthquake Hazard Assessment, is involved in an international effort to improve earthquake forecasting. She studied earthquake engineering in California as an undergraduate, and is now using her research to build better forecasting maps in Canada and other countries.

While previous biomedical research studies have found that genetics and race increase risk for some diseases, a new look into how researchers study genetic triggers of type 2 diabetes suggests that defining race remains an inexact science, with social and historic facts mixing with biology throughout the research process.

The new study by a UC Irvine anthropologist calls into question not only how race-specific information is being gathered and interpreted by the medical community, but how it is presented to the public through media and pharmaceutical marketing.

The rise of multicellular animals about 540 million years ago was a turning point in the history of life. A group of Finnish scientists suggests a new climate-biosphere interaction mechanism for the underlying processes in a new study, which will be published on February 14, 2007 in PLoS ONE, the international, peer-reviewed, open-access, online publication from the Public Library of Science (PLoS).

What caused the extinction of the woolly rhinoceros ten thousand years ago from an area in Europe covering the coasts of the Arctic Ocean in the north to the coasts of the Mediterranean in the south? What caused the extinction of the mammoth while other ice age mammals like the musk ox just barely survived to present day? A new scientific methodological approach to detect genetic material will help researchers to solve the many mysteries of the past.

Subhash Kak, Delaune Distinguished Professor of Electrical and Computer Engineering at LSU, recently resolved the twin paradox, known as one of the most enduring puzzles of modern-day physics.

Stem cell technique helps women grow their own implants

Daily Mail - Women have grown their own breast implants through pioneering stem cell treatment, it emerged yesterday. Scientists harvested the stem cells from the women's own fat and encouraged them to form breast tissue...

New research challenges traditional perceptions of contemporary climate as sole determiner of richness of species.

The climate is changing! But how does that affect nature? New research challenges traditional perceptions of contemporary climate as sole determiner of richness of species.

An artificial nose could be a real benefit at times: this kind of biosensor could sniff out poisons, explosives or drugs, for instance. Researchers at the Max Planck Institute for Polymer Research and the Max Planck Institute of Biochemistry recently revealed a technique for integrating membrane proteins into artificial structures.

Human nerve stem cells transplanted into rats' damaged spinal cords have survived, grown and in some cases connected with the rats' own spinal cord cells in a Johns Hopkins laboratory, overturning the long-held notion that spinal cords won't allow nerve repair.
