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 […]

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. […]

The Search for “Microbial Dark Matter”

Illuminating Biologys Dark Matter

In a newly published study, an international team of researchers detail the search for “microbial dark matter.” Is space really the final frontier, or are the greatest mysteries closer to home? In cosmology, dark matter is said to account for the majority of mass in the universe, however its presence is inferred by indirect effects […]
