A group of astronomers, including from India, have detected a very short, powerful burst of high-energy radiation that lasted for about a second.

The phenomenon detected by NASA's Fermi Gamma-ray Space Telescope is one of the shortest GRBs produced by the death of a star, lasting for less than a second.

Astronomers believe that short gamma-ray bursts of less than two seconds originate when two black holes, two neutron stars, or a black hole and a neutron star merge with each other.

In the major development, a group of astronomers including some Indian scientists has detected a very short, powerful burst of high-energy radiation that lasted for about a second and had been racing toward Earth for nearly half the present age of the universe.

Normally metals and insulators sit at opposite ends of a spectrum of conductivity, but researchers have discovered a material that can switch between those states freely, even at room temperature.

Weed's THC content appears to be getting stronger. What risks does the soaring potency of marijuana pose?

Not all physicians who treat Alzheimer's disease will prescribe the new Alzheimer's drug aducanumab (Aduhelm) -- major hospital systems like the Cleveland Clinic and Mount Sinai in New York City, for example, won't administer the controversial treatment -- but those who will offer the drug need more information about how to use it, a panel of neuroscientists said.

Remarkable things happen when a "squishy" compound of manganese and sulfide (MnS2) is compressed in a diamond anvil, say researchers from the University of Rochester and the University of Nevada, Las Vegas (UNLV).

Appropriate use recommendations for the newly approved Alzheimer disease treatment, aducanumab (Aduhelm; Biogen, Cambridge, MA) have been published in The Journal of Prevention of Alzheimer’s Disease (JPAD).
