A planet-warming El Niño climate phase is now developing, and some models predict it could turn out to be the strongest on record

The protein craze is in full swing and beef consumption is on the rise, particularly in the US, where health agencies are promoting red meat as part of an optimum diet. So, how much beef should we really be eating, and how does it impact our well-being?

The gap between genetics and archaeology leaves us with an unclear picture of where the Neanderthals originated. Columnist Michael Marshall details a surprising new hypothesis that suggests they may have come from us

How do you portray momentum in space accurately? Columnist Chanda Prescod-Weinstein takes a look at the origins of our understanding of motion, which runs from Isaac Newton back to the Zhou dynasty a millennia ago

L-ergothioneine, an antioxidant found in certain mushrooms, is thought to neutralise damaging molecules in uterine cells that may contribute to period pain

Antibodies mistakenly attacking the brain are linked with conditions including schizophrenia, dementia and OCD, prompting a revolution in how we think about mental health conditions

The day when a quantum computer manages to break common encryption, or Q-Day, is fast approaching, and the world is not close to being ready

A study of more than 10 million siblings suggests that firstborns are more likely to be autistic and have allergies, while conditions like migraine and shingles tend to affect their younger sibling

The clouds may look like an oyster, and the stars like pearls, but look beyond.

Comet R3 is brightening rapidly -- will it survive?

Some 60 million light-years away in the southerly

Why does Comet R3 (PanSTARRS) have a wispy tail?

Neutrinos have mass — yet they never flip between left- and right-handed states the way every other massive particle does. The most logical fix is Paul Dirac's: invisible right-handed neutrinos that interact with nothing whatsoever. The math works. It even produces a beautiful explanation for why neutrino masses are so absurdly tiny. But it requires believing in particles that are permanently, in-principle undetectable.

An ultra-hot Jupiter exoplanet orbiting a nearby star gave scientists using the Gemini South telescope a look at how both a star and its hot planet can have similar chemical compositions. The team, led by Arizona State University graduate student Jorge Antonio Sanchez, took spectra of the planet, called WASP-189b, using the Immersion Grating Infrared Spectrograph instrument. The observations measured the abundance of magnesium compared to silicon in the hot planet's atmosphere and allowed the team to compare it to the makeup of its parent star.

Saturn is one of the most recognisable and studied planets in the Solar System, it was the first thing I ever saw through a telescope and yet it is still finding ways to surprise us. New research analysing data from NASA's Cassini spacecraft has revealed a significant and unexpected quirk in Saturn's protective magnetic bubble, one that confirms the giant planets of our Solar System play by completely different rules to Earth.

For the first time in history, scientists have used a spacecraft on the far side of the Moon to search for signals from extraterrestrial intelligence. China's Chang'E-4 lander sat in the most radio quiet location humanity has ever placed an instrument, shielded from Earth's constant electronic chatter by the entire bulk of the Moon itself. They found nothing but that is almost beside the point!
