When patients are put under general anaesthesia, their brain activity frequently slows as they fall asleep. Higher anaesthetic medication dosages can cause an even deeper state of unconsciousness called burst suppression, which is associated with cognitive deficits once the patient awakens.

NASA's retired Compton mission reveals superheavy neutron stars
Updated : 3 years, 2 months ago IST
Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly before it collapsed into a black hole. This fleeting, massive object likely formed from the

NASA missions probe game-changing cosmic explosion
Updated : 3 years, 3 months ago IST
On Dec. 11, 2021, NASA's Neil Gehrels Swift Observatory and Fermi Gamma-ray Space Telescope detected a blast of high-energy light from the outskirts of a galaxy around 1 billion light-years away. The event has rattled scientists' understanding of gamma-ray bursts (GRBs), the most powerful ev

Research: Short gamma-ray bursts traced farther into distant universe
Updated : 3 years, 3 months ago IST
Astronomers have developed the most extensive inventory to date of the galaxies where short gamma-ray bursts (SGRBs) originate. Using several highly sensitive instruments and sophisticated galaxy modeling, the researchers pinpointed the galactic homes of 84 SGRBs and probed the characteristi

To create the Universe's biggest explosions, stars need a partner
Updated : 6 years, 1 month ago IST
Washington D.C. [USA], Jan 18 (ANI): A recent study by Warwick University observed that stars must be in binary systems to create gamma rays. Gamma-ray bursts, caused by massive falling stars, represent the most powerful explosions in the universe.

Gamma-ray bursts are highest energetic explosions ever seen
Updated : 2 years, 4 months ago IST
Washington D.C [USA], Nov 21 (ANI): Gamma-ray bursts (GRBs) are extremely energetic explosions that have been observed in distant galaxies. They give out most of their energy in gamma rays, light which is much more energetic than the visible light we can see with our eyes.
