Science News Roundup: Stem cells give hope for revival of extinct rhinos; British fossil hunters find bones of new dinosaur species and more
Researchers said on Wednesday they identified the pheromone - a chemical produced by an animal that affects the behavior of others of its own species - in the world's most widespread locust species, the migratory locust, or Locusta migratoria.Devdiscourse News Desk | Updated: 14-08-2020 02:49 IST | Created: 14-08-2020 02:29 IST

Back from the dead? Stem cells give hope for revival of Malaysia's extinct rhinos
Some skin, eggs and tissue samples are all that remain of Malaysia's last rhino, Iman, who died last November after years of failed breeding attempts. Now scientists are pinning their hopes on experimental stem cell technology to bring back the Malaysian variant of the Sumatran rhinoceros, making use of cells from Iman and two other dead rhinos.
British fossil hunters find bones of new dinosaur species, cousin to T.Rex
Four bones found on a beach on the Isle of Wight, off England's south coast, belong to a new species of theropod dinosaur, the group that includes Tyrannosaurus rex, researchers at the University of Southampton said on Wednesday. The new dinosaur, which has been named Vectaerovenator inopinatus, lived in the Cretaceous period 115 million years ago and was estimated to have been up to four metres long, the palaeontologists said.
'Secret' life of sharks: Study reveals their surprising social networks
Sharks have more complex social lives than previously known, as shown by a study finding that gray reef sharks in the Pacific Ocean cultivate surprising social networks with one another and develop bonds that can endure for years. The research focused on the social behavior of 41 reef sharks around the Palmyra Atoll, about 1,000 miles (1,600 km) southwest of Hawaii, using acoustic transmitters to track them and camera tags to gain greater clarity into their interactions.
Chemical signal for locust swarming identified in step toward curbing plagues
Scientists have identified a chemical compound released by locusts that causes them to swarm, opening the door to possible new ways to prevent these insects from devouring crops vital to human sustenance as they have for millennia. Researchers said on Wednesday they identified the pheromone - a chemical produced by an animal that affects the behavior of others of its own species - in the world's most widespread locust species, the migratory locust, or Locusta migratoria.
