Phys.org / Wrinkled carbon nitride challenges flat-sheet model for photocatalyst design
Graphene is flat. But that doesn't mean other 2D materials—particularly those containing more than one element—necessarily share the same structure. In the past, researchers have often simplified these materials by modeling ...
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 / Molecular snapshots reveal how bacteria assemble outer membrane proteins
Gram-negative bacteria are responsible for several infections that are hard to treat because of their high resistance to antibiotics. These bacteria possess an outermost layer called the outer membrane that acts as a protective ...
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 / 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 / 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 / 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 ...
Phys.org / Completing the connectome: How pursuing a map of the fly brain rewired neuroscience
When researchers at HHMI's Janelia Research Campus set out to create a map of all the neurons in the fruit fly brain in 2008, many in the scientific community thought they were out of their minds.
Phys.org / Traces of nearly 4 million coins reveal how Rome achieved economic integration
For centuries, the study of ancient history relied primarily on interpreting classical texts and examining inscriptions and archaeological remains at their sites of origin or in museums. In recent years, however, a little-known ...
