Phys.org / Chimpanzees are better at solving resource dilemmas in larger, more tolerant groups

Despite being one of the most cooperative species on the planet, humans routinely fail to manage shared resources sustainably. We overfish from the oceans, burn fossil fuels, and over-prescribe antibiotics; behaviors that ...

Phys.org / Hubble uncovers the secret of blue straggler stars that defy aging

Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue straggler stars, these stellar oddities ...

Phys.org / Human penis size influences female attraction and male assessment of rivals, study suggests

Men assess potential rivals that have a larger penis as more of a threat, both physically and sexually, according to a study by Upama Aich at the University of Western Australia and colleagues, published in PLOS Biology.

Phys.org / Molecular surgery: 'Deleting' a single atom from a molecule

Inserting, removing or swapping individual atoms from the core of a molecule is a long-standing challenge in chemistry. This process, called skeletal editing, can dramatically speed up drug discovery or be applied for upcycling ...

Phys.org / Rule-breaking supermassive black hole discovered in the early universe

An international research team led by scientists at Waseda University and Tohoku University has discovered an extraordinary quasar in the early universe that hosts one of the fastest-growing supermassive black holes known ...

Phys.org / Rethinking where life could exist beyond Earth

Astronomers have long searched for life within a rather narrow ring around a star, the "habitable zone," where a planet should be neither too hot nor too cold for liquid water. A new study argues that this ring is too strict: ...

Phys.org / Sourdough starters reveal a recipe for predicting microbial species survival

People have long said that "bread is life." Now, researchers at Tufts University are using the bubbling mixtures of flour and water known as sourdough starters to explore what shapes life at the microscopic level. Their findings, ...

Phys.org / New code connects microscopic insights to the macroscopic world

In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of degrees and reaches ...

Phys.org / Space station crew credits ultrasound machine for handling in-orbit health crisis

The astronauts evacuated last week from the International Space Station say a portable ultrasound machine came in "super handy" during the medical crisis.

Phys.org / A new optical centrifuge is helping physicists probe the mysteries of superfluids

Physicists have used a new optical centrifuge to control the rotation of molecules suspended in liquid helium nano-droplets, bringing them a step closer to demystifying the behavior of exotic, frictionless superfluids.

Phys.org / Study challenges long-held theory that language is built on grammar trees

Every time we speak, we're improvising. "Humans possess a remarkable ability to talk about almost anything, sometimes putting words together into never-before-spoken or -written sentences," said Morten H. Christiansen, the ...
