Researchers have now identified the first signs of nuclear fission in the cosmos, something that has baffled scientists since the 1950s.


Scientists from Los Alamos National Laboratory and North Carolina State University have uncovered compelling evidence of nuclear fission occurring in the cosmos, specifically during the merger of neutron stars. This discovery challenges long-held beliefs and opens a new chapter in our understanding of heavy element formation in the universe.

Nuclear fusion is the process by which two atomic nuclei combine to form a heavier nucleus, releasing significant amounts of energy. This process plays a crucial role in generating the energy that sustains a star’s luminosity.

Replicating nuclear fusion on Earth involves overcoming challenges such as creating and maintaining the extreme temperatures and pressures required for fusion reactions, achieving stable plasma confinement, and developing materials that can withstand harsh conditions within a fusion reactor.

The robot features eight adjustable water jets in its central and head regions, with a flexible firehose directed by a control unit on a trailing wheeled cart.


Functioning at a rate of 6.6 liters per second, the nozzles expel water with a pressure reaching up to one megapascal. At the tip of the hose, a combination of a traditional camera and a thermal imaging camera is integrated, facilitating the identification and location of the fire. This technological integration enhances the Dragon Firefighter’s firefighting capabilities, according to the team.

The inaugural testing of the system took place during the opening ceremony of the World Robot Summit 2020 (WRS2020), held in September 2021 in Fukushima. Dragon Firefighter “successfully extinguished [49 min 0 s to 51 min 0 s] the ceremonial flame, consisting of fireballs lit by another robot, at a distance of four meters,” said a statement.

“We found that just like in mice, human tears contain a chemical signal that blocks conspecific male aggression. This goes against the notion that emotional tears are uniquely human,” the authors stated.

Overall, the study concluded that the scent of women’s tears might contain chemical signals that can influence men’s behavior by reducing aggressive tendencies.

The company launched 23 of its Starlink internet satellites on a Falcon 9 rocket that had flown 18 times before, breaking its own record for the most flights by a single booster.


SpaceX has achieved a new milestone in its quest to reuse rockets and reduce the cost of spaceflight. The company launched 23 Starlink internet satellites on a Falcon 9 rocket that had flown 18 times before, breaking its record for the most flights by a single booster.

The historic launch occurred from Cape Canaveral Space Force Station in Florida on Saturday (December 23) at 12:33 am EST (0533 GMT). The Falcon 9’s first stage, which debuted in May 2020 on the Demo-2 Crew Dragon mission that carried astronauts for the first time, still bore the faded NASA ‘worm’ logo from that occasion.
