The world is watching as NASA tweaks the odds that asteroid 2024 YR4 will hit Earth. But how threatening is YR4, and how does it compare to other potentially hazardous space rocks?

A team of engineers and physicists at Southern University of Science and Technology, in China, has created a nickel-based material that behaves as a superconductor above the -233°C (40 K) threshold under ambient pressur...

A new optical fiber link between CERN and Paris will provide the Laboratory with an accurate frequency reference, enhancing precision and supporting experiments like ALPHA in their search for matter-antimatter difference...

NASA has been changing the odds of asteroid 2024 YR4 hitting Earth in recent days, but the latest shift significantly downgrades the asteroid's threat level and makes a moon strike more likely.

Researchers have discovered that breathing affects pupil size, with the pupil being smallest during inhalation and largest during exhalation. This newly identified mechanism is independent of external stimuli and could i...

Hair conditioner made using lignin, a polymer found in wood and bark, works just as well as a commercial product - as long as you don't mind the smell

Rock dust, compost and biochar can all help capture carbon dioxide and boost crop yields when sp

Protoclone, an eerily lifelike humanoid robot built for home use, has left social media users aghast. And it's likely to be the first of many.

The US withdrawal from the World Health Organization formally takes one year, but the country has already stopped sharing influenza surveillance with the international body, which could impact the efficacy of the next fl...

Photonics researchers from Tampere University, Finland, and Kastler-Brossel Laboratory, France, have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied to cylindrical syst...

An infant with a fatal genetic disease has survived past the age of 2 with no signs of the condition, thanks to treatment started in the womb.

Tasmanian devils are already being released inside predator-proof sanctuaries in New South Wales, and rewilding advocates believe they could suppress feral cats and foxes across the continent

The 10-part series is narrated by Tom Hanks with a score by Hans Zimmer - here's how to watch The Americas online, on TV and from anywhere.

ETH Zurich researchers have investigated how tiny gas bubbles can deliver drugs into cells in a targeted manner using ultrasound. For the first time, they have visualized how tiny cyclic microjets liquid jets generated b...

Optical atomic clocks can increase the precision of time and geographic position a thousandfold in our mobile phones, computers, and GPS systems. However, they are currently too large and complex to be widely used in soc...

Pope Francis is being treated in hospital for double pneumonia -- but what is this condition, and why might the pope be particularly vulnerable to it?

The practice of purposely looping thread to create intricate knit garments and blankets has existed for millennia. Though its precise origins have been lost to history, artifacts like a pair of wool socks from ancient Eg...

Researchers at the University of Bayreuth have developed a method that makes objects on a magnetic field invisible within a particle stream. Until now, this so-called cloaking had only been studied for waves such as ligh...

Scientists have now mapped the forces acting inside a proton, showing in unprecedented detail how quarks--the tiny particles within--respond when hit by high-energy photons.

The Standard Model (SM), the main physics framework describing elementary particles and the forces driving them, outlines key patterns in physical interactions referred to as gauge symmetries. One of the symmetries it de...

Rain can freefall at speeds of up to 25 miles per hour. If the droplets land in a puddle or pond, they can form a crown-like splash that, with enough force, can dislodge any surface particles and launch them into the air...

Physicists use mathematical assumptions in many situations that forbid time from moving backwards - but that isn't necessarily a reflection of quantum reality
