Biologists at the University of California, San Diego have determined that a protein essential for the normal embryonic development of fruit flies is also used by mammals to assist in the timely healing of cuts and lacerations.
Their discovery, detailed in the June 3 issue of the journal Developmental Cell, provides new insight for scientists into the molecular mechanisms responsible for wound healing in humans and may one day lead to the design of new drugs for individuals whose healing is compromised.
Improving wound healing is particularly important for burn victims and others with slow healing skin lesions like those associated with diabetes. Diabetes now affects more than 17 million Americans and the most prevalent form—type 2, or insulin-resistant diabetes—continues to skyrocket. The U.S. Centers for Disease Control and Prevention estimate that the number of diagnosed cases will increase 165 percent by 2050, as the number of overweight adults and children climbs in the United States.

In meningococci, the RNA-binding protein ProQ plays a major role. Together with RNA molecules, it regulates processes that are important for pathogenic properties of the bacteria.
Meningococci are bacteria that can cause life-threatening meningitis and sepsis. These pathogens use a small protein with a large impact: The RNA-binding...
An analysis of more than 200,000 spiral galaxies has revealed unexpected links between spin directions of galaxies, and the structure formed by these links...
Two prominent X-ray emission lines of highly charged iron have puzzled astrophysicists for decades: their measured and calculated brightness ratios always disagree. This hinders good determinations of plasma temperatures and densities. New, careful high-precision measurements, together with top-level calculations now exclude all hitherto proposed explanations for this discrepancy, and thus deepen the problem.
Hot astrophysical plasmas fill the intergalactic space, and brightly shine in stellar coronae, active galactic nuclei, and supernova remnants. They contain...
In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...
Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.
