Just like humans, chimps have rhythm when drumming, which suggests that the trait evolved in our common ancestor

We tend to think of habitability in terms of individual planets and their potential to host life. But barring outliers like rogue planets with internal heating or icy moons with subsurface oceans created by tidal heating, it's exoplanet/star relationships that generate habitability, not individual planets. New research emphasizes that fact.

Our bodies emit a stream of low-energy photons, and now experiments in mice have revealed that this ghostly glow is cut off when we die

With season 2 unfolding, the science of the fungal horror drama is becoming shakier. It is a pity that the creators haven’t thought about terrifying scenarios of real-life infection, says Corrado Nai

Following on from our first list, we asked New Scientist staff to pick even more of their favourite sci-fi books of all time. From Isaac Asimov and Ursula K. Le Guin to Star Wars – the list has it all this time, we hope…

Very large hail – hailstones more than 5 centimetres in diameter – poses a growing threat to Europe as the climate warms, with increasing risk of expensive damage to cars and property

"I wish Vinay all the best for his new role. It's a whole new state of play when the buck stops with you."

Researchers developed FaceAge, an AI tool that calculate's a patient biological age from a photo of their face. In a new study, the researchers tied FaceAge results to health outcomes in people with cancer: When FaceAge estimated a younger age than a cancer patient's chronological age, the patient did significantly better after cancer treatment, whereas patients with older FaceAge estimates had worse survival outcomes.

Over the past decade or so, astronomers have speculated about the characteristics of rogue planets in the Milky Way Galaxy. These "free-floating" worlds don't orbit stars, but instead roam the spaceways. They're hard to spot with current technology, but the upcoming Nancy Grace Roman Space Telescope (Roman) will be a perfect instrument to find them and give insights into the history and features they may have in common with Solar System worlds.

One of the unanswered questions in astronomy is just how supermassive black holes grew so big, so quickly. A team of astronomers have tried to answer this question by searching for actively feeding supermassive black holes (aka quasars) as a way to measure how much material material they are actually accumulating. They studied nebulae near the quasars that light up with the quasar is releasing radiation and found that many of the more distant quasars have only been active for a few hundred thousand years, not long enough to grow to the size we see today.

New technique for cell or drug delivery, localization of bioelectric materials, and wound healing uses ultrasound to activate printing within the body.

Kosmos 482, a Soviet spacecraft that never made it beyond Earth’s orbit on its way to Venus, is due to come crashing down on 9 or 10 May

Engineers developed a ping-pong-playing robot that quickly estimates the speed and trajectory of an incoming ball and precisely hits it to a desired location on the table.

Environmental engineers have developed critical methods to remove toxic selenium from water.

In space, energetic neutrinos are usually paired with energetic gamma rays. Galaxy NGC 1068, however, emits strong neutrinos and weak gamma rays, which presents a puzzle for scientists to solve. A new paper posits that helium nuclei collide with ultraviolet photons emitted by the galaxy's central region and fragment, releasing neutrons that subsequently decay into neutrinos without producing gamma rays. The finding offers insight into the extreme environment around the supermassive black holes at the center of galaxies like NGC 1068 and our own and enhances our understanding of the relationships between radiation and elementary particles that could lead to technological advances we haven't yet imagined.

Mercury is released by environmental and human-driven processes. And some forms, specifically methylmercury, are toxic to humans. Therefore, policies and regulations to limit mercury emissions have been implemented across the globe. And, according to new research, those efforts may be working. Researchers found that atmospheric mercury levels have decreased by almost 70% in the last 20 years, mainly because human-caused emissions have been reduced.

A new study analyzes the results of a randomized controlled trial (RCT) that showed that brick kiln owners in Bangladesh are willing and able to implement cleaner and more efficient business practices within their operations -- without legal enforcement -- if they receive the proper training and support, and if those changes are aligned with their profit motives. The study is the first to rigorously demonstrate successful strategies to improve efficiency within the traditional brick kiln industry.

Supermassive Black Holes reside at the center of large galaxies, where they dominate their surroundings and sometimes eat stars. When they gobble up a star, they emit a distinctive light flare. This makes it easier for astronomers to pinpoint their location. Astronomers have detected one of these flares offset from a galactic center. Is the black hole shifting its location?
