No evidence of space aliens so far in the Pentagon’s UFO deep-dive
The Pentagon’s new push to investigate reports of UFOs has so far not yielded any evidence to suggest that aliens have visited Earth or crash-landed here, senior military leaders said on Friday. However, the Pentagon’s effort to investigate anomalous, unidentified objects — whether they are in space, the skies or even underwater — led to hundreds of new reports that are now being investigated, they say.
Robotic arm to inspect leaky Soyuz spacecraft, Russia says
A 17-metre-long Canadian-made robotic arm on the International Space Station will inspect a docked Soyuz spacecraft after a leak was noticed just before a spacewalk last week, Russia’s state space corporation said on Sunday. After the spacewalk was called off on Dec. 15, Roscosmos said there had been damage to the outer skin of an instrument assembly compartment of the Soyuz MS-22 capsule. It said there was a coolant leak.
Scientists discover hammerhead shark nursery in Ecuador’s Galapagos
A team of researchers has discovered a nursery of baby hammerhead sharks off an island in Ecuador’s Galapagos archipelago, a finding that could help protect the species from the threat of extinction. The so-called haven for hammerhead hatchlings, who are less than a year old, was discovered near Isabela Island, the Galapagos’ largest island, and offers refuge for the sharks during mating and early development stages.
