Over half of solid tumour patients analysed tested positive for cancer cell death

Cyclacel Limited, the UK-based biopharmaceutical company, reported today that it demonstrated through state-of-the-art biomarker technology that CYC202 (R-roscovitine), its lead CDK inhibitor drug candidate, appears to induce cancer cell suicide or apoptosis in patients receiving the drug. Details of the biomarker data obtained with CYC202 were reported today at an oral presentation at the American Asso

’Lizards gone wild’

Despite social notions of race, human populations around the world are genetically so similar that geneticists find no different sub-species among them. The genetic continuity of human populations is the exception rather than the rule for most animal species, however.

Richard Glor, graduate evolutionary biology student in Arts & Sciences at Washington University in St. Louis, has found extensive genetic differentiation among populations of numero

’The brain’s Timex’

Getting over jet lag may be as simple as changing the temperature –your brain temperature, that is.

That’s a theory proposed by Erik Herzog, Ph.D. assistant professor of biology in Arts & Sciences at Washington University in St. Louis. Herzog has found that the biological clocks of rats and mice respond directly to temperature changes.

Biological clocks, which drive circadian rhythms, are found in almost every living organis

Scouring the genome of a wild Mexican potato, scientists have discovered a gene that protects potatoes against late blight, the devastating disease that caused the Irish potato famine.

The discovery of the gene and its cloning by scientists at the University of Wisconsin-Madison was reported today (July 14) in online editions of the Proceedings of the National Academy of Sciences (PNAS).

The identification of the gene, found in a species of wild potato known as ´ Solanum bulboca

Warmer ocean temperatures may be harming reproduction of the tufted puffin in western Canada and if global temperatures continue to increase, the species could be at risk, says a new study co-authored by a University of Alberta researcher.

Throughout the last two decades, uncharacteristically warm sea-surfaces have persisted near Triangle Island–off the coast of British Columbia–a haven for these birds. Researchers have been studying the reproductive performance of tufted puffins there si

Depression is the second-leading cause of disability worldwide, affecting nearly 10% of the population. According to George S. Zubenko, M.D., Ph.D., professor of psychiatry at the University of Pittsburgh School of Medicine and adjunct professor of biology at Carnegie Mellon University, women are twice as likely as men to develop depression, and genetic differences appear to account for some of that disparity.

These latest results build on research published by Dr. Zubenko and his team in O
