A new paper proposes that the record-setting gamma ray burst that reached Earth on Oct. 9, 2022, was so bright and so long-lasting because it originated in a star as it collapsed into a black hole.The once-in-a-millennium blast of energy — later dubbed the Brightest of All Time (BOAT) — has continued to puzzle scientists, who say it was 70 times brighter than the second most powerful burst on record. An explanation would help to demystify the tremendous outpourings of energy, which are detec ...read more
Sitting on the shoulder of the constellation of Orion with a distinctly reddish hue, Betelgeuse is one of the more recognizable stars in the night sky. But it is also one of the fastest changing. While Ptolemy described it orange-tawny, Chinese observers three centuries earlier say it was yellow. More recently, astronomers classified Betelgeuse as a red giant, a star that is near the end of its life. That meant Betelgeuse is due to explode as a supernova sometime in the next few hundred thousand ...read more
Clodomiro Picado, one of Costa Rica’s foremost scientists, conducted research on venomous snakes in Central America in the early-20th century and advocated for better products tailored to the types of snakes that lived in the area. The institute now named after him — the University of Costa Rica’s Clodomiro Picado Institute — is one of few in the world helping people bitten by snakes in Latin America and Africa. Before the institute was created, people in Costa Rica and surrounding coun ...read more

NASA has long understood that abnormal amounts of cerebrospinal fluid accumulate deep in the brains of astronauts exposed to microgravity. In 1983, the space agency received a patent for a “ventricular catheter” designed to be inserted into the brains of astronauts, to relieve the pressure.And since then, the space agency has funded research into the problem. A new study has found that astronauts in space for six or more months develop the worst hydrocephalus, meaning they had the most enlar ...read more
