A molecular thermometer for the distant universe 
Astronomers have made use of ESO’s Very Large Telescope to detect for the first time in the ultraviolet the carbon monoxide molecule in a galaxy located almost 11 billion light-years away, a feat that had remained elusive for 25 years.

Researchers synthesize molecule with self-control
Plants have an ambivalent relationship with light. They need it to live, but too much light leads to the increased production of high-energy chemical intermediates that can injure or kill the plant.

Study shows how T cell's machinery dials down autoimmunity
A St. Jude Children’s Research Hospital study shows that T cells, the body’s master immune regulators, do not use simple on/off switches to govern the cellular machinery that regulates their development and function. Rather, they possess sophisticated molecular controls that enable them to adjust their function with exquisite precision.

Biodiversity -- it's in the water
What if hydrology is more important for predicting biodiversity than biology" Research published in the May 8th issue of the journal Nature challenges current thinking about biodiversity and opens up new avenues for predicting how climate change or human activity may affect biodiversity patterns.

Researchers demonstrate safety of gene therapy using adult stem cells
A new study by UC Davis researchers provides evidence that methods using human bone marrow-derived stem cells to deliver gene therapy to cure diseases of the blood, bone marrow and certain types of cancer do not cause the development of tumors or leukemia. The study was published online in the May 6, 2008 issue of Molecular Therapy.

Scientists discover how some bacteria survive antibiotics
Researchers at the University of Illinois at Chicago have discovered how some bacteria can survive antibiotic treatment by turning on resistance mechanisms when exposed to the drugs. The findings, published in the April 24 issue of the journal Molecular Cell, could lead to more effective antibiotics to treat a variety of infections.

Researchers discover molecular basis of a form of muscular dystrophy
People with limb-girdle muscular dystrophy are missing a protein called c-FLIP, which the body uses to prevent the loss of muscle tissue. By targeting the cellular and molecular mechanisms responsible for creating this protein, scientists could develop new drugs to stop muscle wasting from limb-girdle muscular dystrophy and other conditions.

Putting more meat on the theory that dinosaurs’ closest living relatives are modern-day birds, molecular analysis of a shred of 68-million-year-old Tyrannosaurus rex protein – along with that of 21 modern species – confirms that dinosaurs share common ancestry with chickens, ostriches, and to a lesser extent, alligators.

A commonly used chemotherapy drug causes healthy brain cells to die off long after treatment has ended and may be one of the underlying biological causes of the cognitive side effects -- or "chemo brain" -- that many cancer patients experience. That is the conclusion of a study published today in the Journal of Biology.
