New research from Colorado State University shows that the function of all genes in mammals is based on circadian – or daily – rhythms. The study refutes the current theory that only 10 percent to 15…

Researchers at the University of Pittsburgh have successfully cultured human hematopoietic stem cells from fat tissue, suggesting another important source of cells for patients undergoing radiation…

For the first time, a text has been found in Old Persian language that shows the written language in use for practical recording and not only for royal display. The text is inscribed on a damaged…

If the Listeria monocytogenes bacteria behind food poisoning are starved of oxygen, they are liable to turn really nasty according to research published today. Limiting oxygen produces bacteria up to…

A major cause of human and animal infections, Staphylococcus aureus bacteria may evade the immune system’s defences and dodge antibiotics by climbing into our cells and then lying low to avoid…

The innate immune response is the body's first line of defense against pathogen infection. Dr. Xin Li (University of British Columbia) and colleagues report that three proteins work together in the…

Researchers at the University of Edinburgh have shown that hormone therapy can extend life in ovarian cancer patients, giving women a new alternative to chemotherapy. The study has proved for the…

Yes, you secretly like giving your money to the government. University of Oregon scientists have found that doing things like donating money to charity or even paying your taxes can give you the…

Subjecting mice to repeated emotional stress, the kind we experience in everyday life, may contribute to the accumulation of neurofibrillary tangles, one of the hallmarks of Alzheimer’s disease,…

It may sound counterintuitive to use a microbial protein to improve water quality but some bacteria are doing just that to protect themselves from potentially toxic nanoparticles in their own…

NASA's Hubble Space Telescope has teamed up with the W.M. Keck Observatory to precisely measure the mass of Eris, the largest member of a new class of dwarf planets in our solar system. Eris is 1.27…

Some advice my dad gave me: "If your wife says she never dreams about sex with another man, she's lying. If she says she never dreams about sex with another woman, she's lying then too." He may have…

Electrically charged gas in the magnetosphere of Saturn suggests volcanic activity on two of its moons. The direction of the ejected electrons points back towards Tethys and Dione. Previously it had…

"Innovative" science classes - new ways of teaching that are interactive, non-boring and therefore in defiance of every method that made America the home of great scientists for 150 years, are all…

The long supposed connection between mind and music has been further demonstrated by an international collaboration of physicists led by Simone Bianco and Paolo Grigolini at the Center for Nonlinear…

The consumption of sweetened soft drinks by children has more than doubled between 1965 and 1996 but few studies have been able to investigate the link between diet and the body’s energy balance…

Biologists at the University of California, Riverside have identified the genes, and determined the DNA sequences, for two key proteins in the "dragline silk" of the black widow spider - an advance…

Researchers at the University of Pennsylvania have created the first three-dimensional optical images of human breast cancer in patients based on tissue fluorescence. Fluorescence diffuse optical…

Ultrafast intramolecular electronic charge separation during photo-chemical reactions cause up to tenthousand surrounding molecules to perform aligning pirouettes. Researchers observed for the first…

Physicists of the DZero experiment at the Department of Energy's Fermi National Accelerator Laboratory have discovered a new heavy particle, the Îb(pronounced "zigh sub b") baryon, with a mass of 5…
