Martian Valleys Likely Caused by Ancient Snowfall or Rain

Ancient Snowfall Likely Caused Water Carved Valley on Mars

In a new study, scientists from Brown University suggest that certain valleys on Mars appear to have been caused by runoff from orographic precipitation. Providence, Rhode Island (Brown University) — Valley networks branching across the Martian surface leave little doubt that water once flowed on the Red Planet. But where that ancient water came from […]

New Technique Allows Researchers to Control Genes with Light

New Technique Can Rapidly Turn Genes On and Off

A team of researchers from MIT and the Broad Institute have developed new technology based on optogenetics that allows scientists to start or stop the expression of any genes by simply shining light on the cells. Although human cells have an estimated 20,000 genes, only a fraction of those are turned on at any given […]

Cassini Helps Explain the Mystery of the Missing Waves on Titan

Cassini is Helping Solve Mystery of the Missing Waves on Titan

A new four minute ScienceCast video and new Cassini RADAR Team study examine the surface of Titan, trying to explain the mystery of the missing waves. One of the most shocking discoveries of the past 10 years is how much the landscape of Saturn’s moon Titan resembles Earth. Like our own blue planet, the surface […]

Resveratrol Blocks the Positive Effects of Exercise Training

Resveratrol Blocks the Positive Effects of Exercise Training

A new study from the University of Copenhagen revealed that eating a diet rich in antioxidants may actually counteract many of the health benefits of exercise, including reduced blood pressure and cholesterol in older men. In older men, a natural antioxidant compound found in red grapes and other plants – called resveratrol – blocks many […]

GERDA Experiment Phase I Results – No New Evidence That Neutrinos Are Their Own Antiparticles

GERDA Experiment Supplies No New Evidence That Neutrinos Are Their Own Antiparticles

The phase I results from the GERDA experiment have revealed no signal of neutrino-less double beta decay in Ge-76, ruling out an earlier claim for a signal by others. Neutrinos are the most elusive particles having extremely weak interactions with all other particles. They have rather unusual properties and are even expected to be identical […]

Two-Drug Combination Could Be the Key to Curing Cancer

Research Shows that Using Two Drugs in Targeted Therapy Can Help Eliminate Cancer

A new study from researchers at Harvard suggests that using a combination of two drugs in a “targeted therapy” effort could effectively cure nearly all cancers. New research conducted by Harvard scientists is laying out a road map to one of the holy grails of modern medicine: a cure for cancer. As described in a […]

Planets Orbiting Cooler Stars May Be More Likely to Remain Ice Free

New Climate Model Research Suggests Planets Orbiting Cooler Stars Are Likely to Remain Ice Free

New climate model research from astronomers at the University of Washington suggests that planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter star due to the interaction of a star’s light with ice and snow on the planet’s surface. Stars emit different types of light. Hotter stars emit high-energy […]

NASA’s Hubble Views NGC 4866

Hubble Views NGC 4866

Hubble captured this image of NGC 4866, a lenticular galaxy situated roughly 80 million light-years from Earth. The constellation of Virgo (The Virgin) is the largest of the Zodiac constellations, and the second largest overall after Hydra (The Water Snake). Its most appealing feature, however, is the sheer number of galaxies that lie within it. […]
