It is believed that bees, like birds and butterflies, use the sun as a compass for navigation, unlike mammals who use a mental map. However, Randolf Menzel, a neurobiologist at the Free University of Berlin, and his team suggest that bees do not rely only upon on the sun. Read on to find out more. 

Validating the recent finding that females in the animal kingdom are polyandrous, researchers have found that female fire salamanders mate with several males. Read on to know more. 

Guy Levy, a neuroscientist at the Hebrew University of Jerusalem, and his team studied how an octopus avoids latching onto itself. They cut off an octopus’s arm and subjected it to a series of tests, and found that octopus arms have a built-in mechanism that prevents the suckers from grabbing octopus skin.

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. 

Scientists have discovered the first binary system ever known to consist of a black hole and a Be star. Read on to know more. 

In a new study, scientists managed to increase the lifespan of a genus of small flies by altering the symbiotic relationship between bacteria and the cells lining the intestine. Read on to find out more. 

According to a new study, light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics. Read on to know more. 

The interaction between the sun and Earth’s magnetic fields sometimes cause storms of explosive nature in the space near Earth. Understanding these interactions is important to help protect and improve the performance of satellites. NASA’s Magnetospheric Multiscale (MMS) mission’s results have provided the first direct and detailed observation of magnetic reconnection. Read more about these findings here.

Researchers at the U.S. Department of Energy have discovered that sodium bismuthate can exist as a form of quantum matter called a 3D topological Dirac semimetal (3DTDS). Read on to know more. 

Exposure to blue light during the day directly and immediately improves alertness and performance, says a new study. Researchers from Brigham and Women's Hospital (BWH) compared the effects of exposure to blue light with exposure to an equal amount of green light on alertness and performance in 16 study participants.
