By Akash Sriram and Joey Roulette April 1 (Reuters) – NASA’s Artemis II mission is shaping up to be more than just the next step in returning humans to the moon — it is a key test of whether the agency’s traditional contractor-built systems can remain viable in a rapidly shifting space industry. The mission,…
In animal societies as in human ones, some individuals regularly produce resources while others appropriate them. Contrary to what evolutionary theories had previously suggested, these social roles do not depend solely on innate individual predispositions. A study in mice conducted by scientists from CNRS² and Sorbonne Université shows that the distribution and stabilization of these…
If the star is sufficiently massive, this will cause the near-instantaneous onset of oxygen fusion, releasing a massive burst of energy. That energy is thought to be enough to completely destroy the star without leaving a remnant black hole behind. Alternatively, smaller bursts of oxygen fusion may blast away the star’s outer layers, leaving a…

Many seemingly complex magic tricks rely on a simple mix of old-fashioned slight-of-hand and misdirection. Some magicians talk to the audience as a form of misdirection, which sounds like a logical strategy, at first glance. Even the most skeptical…
For the first time ever, an astronomer has witnessed a comet changing the speed and direction of its own spin, thanks to newly analyzed Hubble Space Telescope photos. The unexpected reversal was triggered by “outgassing” jets that shot an icy mix of gas and dust into the solar system, according to a new study. The…
Smart homes are supposed to make life easier, but you might know that’s not always the case if you’ve yelled at a speaker that misunderstood a simple command. Following last month’s major update to Gemini for Home, the company is rolling out Google Home v4.2, focusing on fixing these small but frustrating experiences, along with…
The weather rules include atmospheric electricity, types of cloud, specifically cumulus and disturbed weather like rain or strong winds. Using a percentage chance of a violation of the rules, launch weather officers use a combination of meteorological and climatological data, local knowledge, and experience to forecast this probability. Lightning is one of the biggest risks,…
It wasn’t supposed to be a breakthrough — just a quiet moment at the end of a long day for paleontologist Rudy Lerosey-Aubril. Under the microscope, something refused to fit. A 500-million-year-old arthropod showed the wrong kind of front limb. Where there should have been a sensory antenna, there was a pincer. That pincer is…
CAPE CANAVERAL, Fla. (AP) — NASA began fueling its moon rocket Wednesday for humanity’s first lunar trip in more than half a century, aiming for an evening liftoff with four astronauts. Tensions were high as hydrogen fuel started flowing into the rocket hours ahead of the planned launch. Dangerous hydrogen leaks erupted during a countdown…
Shortly after his attorney entered a plea of not guilty, Tiger Woods announced he will seek treatment “to prioritize my well-being and work toward lasting recovery.” The golf legend was arrested Friday on suspicion of DUI with property damage and refusal to submit to a urinalysis stemming from a rollover crash near his home on…
