Phys.org / Brainless sea sponges use sunset to prepare for metamorphosis—and attach in 30 minutes

Well before I start collecting coats, keys or shoes, my dog always knows when we're about to leave. By picking up on subtle cues, he anticipates our next movements, reminding me he's smarter than he often shows. But anticipation ...

Phys.org / Ultrafast sample spinning improves protein structural data by dizzying proportions

Researchers have been elucidating the structures of complex molecules for more than 100 years using a variety of techniques. Some molecular structures, however, are more difficult to solve than others.

Phys.org / Patent-reading AI could strengthen early warning systems for hazardous chemicals

Patents are far more than legal documents protecting intellectual property. They are a vast source of scientific information about chemicals under development, often years before they appear in products or in the environment. ...

Phys.org / How hibernating squirrels retain sense of touch in the cold

For most mammals, cold suppresses neural activity and diminishes the sense of touch. But the thirteen-lined ground squirrel can detect touch in conditions as low as 4°C (39°F), about as cold as the inside of a refrigerator, ...

Phys.org / 'Soft crosslinking' strategy makes brittle, glassy plastics tougher

Glassy polymers are those whose chains become immobilized below their glass transition temperature. The immobilized chains make them hard and stiff but also brittle, causing them to fracture when stretched. One promising ...

Phys.org / Why doesn't Venus have a moon? A new study may have the answer

Venus is one of the solar system's most unusual planets. It may sometimes be called "Earth's twin" because of its similar size and density, but it rotates on its axis in the opposite direction of most planets, has surface ...

Phys.org / Salt may have helped turn Earth into a frozen world 700 million years ago

Earth may have been pushed deeper into a global deep freeze by something surprisingly ordinary: salt. Around 700 million years ago, Earth entered periods of extreme glaciation known as Snowball Earth, when ice is thought ...

Phys.org / Away from grand temples, a recycled Bronze Age burial mound became the focus of a Roman religious complex

The Romans were master engineers, building sprawling road networks, towering aqueducts and arenas across their empire. They were also good at recycling. New research has revealed that they turned the remains of a 4,000-year-old ...

Phys.org / The biggest black hole merger ever observed could be less massive than it appears

Gravitational waves are ripples in spacetime created when pairs of black holes spiral into each other and eventually merge. But if this ripple has been warped by another massive object on its way to Earth, a new analysis ...

Phys.org / A pair of spacecraft draw closer to Mercury after nearly decade-long voyage

Two Mercury-bound spacecraft left their mother ship behind on Thursday and headed down the home stretch of their nearly decade-long voyage to the solar system's smallest and closest-to-the-sun planet.

Phys.org / Antarctic expedition reveals why Southern Ocean clouds remain one of climate science's greatest challenges

The Southern Ocean plays a pivotal role in regulating Earth's climate, yet the clouds that blanket this remote region remain among the least understood features in atmospheric science. By controlling both incoming sunlight ...

Phys.org / How a plant's refusal to self-pollinate could help India grow more of its own cooking oil

Most people assume plants reproduce through whatever pollen happens to land on them. This is not true. A collaborative research initiative involving the Indian Institute of Technology Gandhinagar (IITGN) has mapped and functionally ...
