There is a widespread belief that altruism and equality drive social behaviour in traditional hunter-gatherer societies, but the truth is more surprising and complex

Albert Einstein and Niels Bohr had an ongoing rivalry about the true nature of quantum mechanics, and came up with a thought experiment that could settle the matter. Now, that experiment has finally been performed for real

A researcher from the University of Tokyo and a U.S.-based structural engineer developed a new computational form-finding method that could change how architects and engineers design lightweight and free-form structures covering large spaces. The technique specifically helps create gridshells, thin, curved surfaces whose members form a networked grid. The method makes use of NURBS surfaces, a widely used surface representation format in computer-aided design (CAD). It also drastically reduces computation cost — a task that previously took 90 hours on a high-end GPU completes in about 90 minutes on a standard CPU.

From legal challenges to lesser-known apps, the teenagers of Australia are already preparing to push back against a law that will see under 16s banned from social media

It’s been over two years since the samples from Bennu gathered by OSIRIS-REx were returned to Earth. But there’s still plenty of novel science coming out of that 121.6 g of material. Three new papers were released recently that describe different aspects of that sample. One in particular, from Yoshihiro Furukawa of Tohoku University in Japan and their co-authors, has already attracted plenty of attention, including from US Senator (and former astronaut) Mark Kelly. It shows that all of the building blocks for early life were available on the asteroid - raising the chances that planets throughout the galaxy could be seeded with the abiotic precursors for life.

What can mapped drainage systems on Mars teach scientists about the Red Planet’s watery past? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of scientists from the University of Texas at Austin (UT Austin) conducted a first-time mapping study involving Martian river basins. This study has the potential to not only gain insight into ancient Mars and how much water existed there long ago but also develop new methods for mapping ancient river basins on Mars and potentially other worlds.

Scientists have launched COLIS, a special laboratory aboard the International Space Station designed to study how everyday materials like sunscreens, mayonnaise, and medications behave in near zero gravity. Researchers discovered that gravity influences the long term stability of soft matter far more dramatically than previously understood, affecting how these materials age and restructure at the molecular level. This research could fundamentally improve how we design everything from controlled release drugs to self assembling materials, demonstrating that understanding materials in space offers unexpected benefits for life on Earth.

On a summer day in 709 BCE, scribes at the Lu Duchy Court in ancient China looked up to witness something extraordinary. The Sun vanished completely from the sky, and in its place hung a ghostly halo. They recorded the event carefully, noting that during totality the eclipsed Sun appeared "completely yellow above and below." Nearly three millennia later, that ancient observation has helped modern scientists measure how fast Earth was spinning and understand what our Sun was doing at a time when Homer was composing poetry.

Dr. Makary desperately wants everyone to know he is a brave, free-thinker, able to see the world objectively and without bias, smarter than 99% of his peers. However, in reality his brain is cooked.

Kyushu University scientists have achieved a major leap in fuel cell technology by enabling efficient proton transport at just 300°C. Their scandium-doped oxide materials create a wide, soft pathway that lets protons move rapidly without clogging the crystal lattice. This solves a decades-old barrier in solid-oxide fuel cell development and could make hydrogen power far more affordable.

Researchers engineered a strained germanium layer on silicon that allows charge to move faster than in any silicon-compatible material to date. This record mobility could lead to chips that run cooler, faster, and with dramatically lower energy consumption. The discovery also enhances the prospects for silicon-based quantum devices.

An international team has made a significant breakthrough in understanding the tectonic evolution of terrestrial planets. Using advanced numerical models, the team systematically classified for the first time six distinct planetary tectonic regimes. Their work provides a unified theory on the geological evolution of both Earth and Venus.

Intermediate mass stars experience periods of rapid growth in their late stages of formation. The growing young star emits more radiation that encourages greater accretion. Rather than depleting their protoplanetary disks and preventing gas giants from forming, the opposite is true.

In a recent paper, a team of SETI and astrobiology specialists examines four controversial claims about the existence of extraterrestrial life. From these, they present recommendations for scientists and science communicators when addressing future claims of discovery.

Voters change their opinions after interacting with an AI chatbot – but, encouragingly, it seems that AIs rely on facts to influence people

The AI industry consumes vast amounts of energy, fresh water and investor cash. Now it also needs memory chips - the same ones used in laptops, smartphones and games consoles

Climate data and historical accounts suggest that crop failures in the 1340s prompted Italian officials to import grain from eastern Europe, and this may have carried in the plague bacterium

Penn State researchers created seven new high-entropy oxides by removing oxygen during synthesis, enabling metals that normally destabilize to form rock-salt ceramics. Machine learning helped identify promising compositions, and advanced imaging confirmed their stability. The method offers a flexible framework for creating materials once thought impossible to synthesize.
