Scientists working in the Channel island of Jersey have stumbled upon geological deposits that may help us understand the disappearance of the Neanderthal populations from the region. Read on to know more. 

In a recent study, physicists placed the strictest limit yet on how much the alpha could change with the density of nearby matter. Read on for more details. 

Researchers have found evidence that magnetic waves in a polar coronal hole contain enough energy to heat the corona, possibly explaining the solar physics conundrum called the “coronal heating problem.” Read on to know more. 

Rosen et al. show that 3,3’-diindolylmethane—produced in the stomach after consuming cruciferous vegetables such as broccoli—protects against ionizing radiation. Read on to know more. 

Researchers Ramkumar et al. have uncovered evidence that the Smurf2 protein, which typically plays an “enforcer” role in cellular aging, could suppress tumor cells. Read on to know more.
