Can naked mole rats peacefully hand over power?‎

Naked mole rats keep kingdoms underground. One queen bears all the children, while others maintain complex subterranean tunnels, forage for food, take care of newborns, and perform other necessary upkeep. This society hinges on the central pillar of a singular queen. What happens when her fertility declines or is impaired?

Referee decisions in soccer frequently overturned following VAR-assisted review: No external influences found‎

In an analysis of a video-assisted, pitch-side review of soccer (UK football) referee calls in the English Premier League, referees overturned their original call 95% of the time. However, these decisions had no statistical link to crowd size, the score or quarter when the call was made, or whether the call was regarding the home versus away team.

Any color you like: Scientists create 'any wavelength' lasers in tiny circuits for light‎

Computer chips that cram billions of electronic devices into a few square inches have powered the digital economy and transformed the world. Scientists may be on the cusp of launching a similar technological revolution—this time using light.

The universe's most powerful telescope‎

SN 2025mkn is a Type II supernova and it wasn't supposed to be visible at all. The violent death of a massive star that had exhausted its nuclear fuel and collapsed under its own gravity sits at a redshift of 1.371. That places it roughly 9 billion light years away. At that distance, an ordinary stellar explosion simply doesn't produce enough light to study in any useful detail. Yet astronomers can see this one with extraordinary clarity and we have gravity to thank.

Reading the moon's buried past‎

The lunar south pole looks chaotic from orbit. Craters heaped upon craters, ancient basins, scarps and slopes tumbling in every direction, it is without doubt, one of the most geologically complicated terrains in the inner solar system. That aside, it's exactly where we intend to send people, since understanding what lies beneath that battered surface isn't just scientific curiosity. It's the essential groundwork for everything that follows.

Blended satellite data reveal what drove methane's 2019–2024 rise worldwide‎

Because methane has around 80 times the warming potential of CO2 over a 20-year period, it has been a major focus for climate action groups. The Global Methane Pledge, launched at COP26 in November 2021, aims to cut human-caused methane emissions by 30% by 2030.
