A study lead by Rajesh Agarwal, PhD, investigator at the University of Colorado Cancer Center and professor at the Skaggs School of Pharmaceutical Sciences, found that grape seed extract both damages cancer cells’ DNA through increased reactive oxygen species and stops the pathways that allow repair as seen by decreased levels of the DNA repair molecules Brca1 and Rad51 and DNA repair foci.

Researchers at the University of Western Australia found out that drinking up to eight cups of tea a day lowers blood pressure and could prevent heart disease If their experiment was emulated by the general population, the number of people with high blood pressure would be cut by 10% and the risk of heart disease would fall by between seven and 10%.

A study, conducted by Nathan Pipitone at Adams State College and Gordon Gallup from SUNY-Albany, the researchers asked three groups of men to listen to voice recordings of ten women who counted from one to five at four different points over their menstrual cycle. According to Popular Science, all four recordings were played in a random order and then the first group of men were asked to guess which were made while the women were on their period.

The discoveries by NASA’s Kepler space telescope boost the list of confirmed extra-solar planets to 729, including 60 credited to the Kepler team. The telescope can detect slight but regular dips in the amount of light coming from stars. Scientists can then determine if the changes are caused by orbiting planets passing by, relative to Kepler's view.

Nearly half of giant asteroid Vesta is expected to be so cold and receive so little sunlight that it may have retained ice for billions of years, researchers say. Though temperatures on Vesta fluctuate during the year, the model predicts that the average annual temperature near Vesta’s north and south poles is less than roughly minus 200 degrees Fahrenheit (145 kelvins).

The fanged, dog-sized beasts it came from a time when all the continents were fused together into one land mass called Pangaea.
