One of the challenges of understanding cancer is trying to determine the mechanisms that drive metastasis, or the process by which tumor cells are able to spread throughout the body. Wistar researchers describe how melanoma tumors use "phenotype switching" -- changing their outward appearance -- can result in melanoma cells...

Claiming housework as exercise may be a mistake finds research. For the same amount of time people who included housework in their self recorded moderate to vigorous physical activity tended to be heavier than those whose time was spent in other forms of exercise.

Supermassive black holes: every large galaxy's got one. But here's a real conundrum: how did they grow so big? A new article pits the front-running ideas about the growth of supermassive black holes against observational data -- a limit on the strength of gravitational waves, obtained with CSIRO's Parkes radio telescope in...

Almost a year after Hurricane Sandy, parts of New York and New Jersey are still recovering from billions of dollars in flood damage. A geologist sees the possibility of damage from storms smaller than Sandy in the future. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/n...

Paleoanthropologists have uncovered the intact skull of an early Homo individual in Dmanisi, Georgia. This find is forcing a change in perspective in the field of paleoanthropology: human species diversity two million years ago was much smaller than presumed thus far. However, diversity within the Homo erectus, the first global...

Changes in gene regulation have been used to study the evolutionary chasm that exists between humans and chimpanzees despite their largely identical DNA. However, scientists have discovered that mRNA expression levels, long considered a barometer for differences in gene regulation, often do not reflect differences in protein...
