Phys.org / Bering Land Bridge base camp reveals what life was like nearly 14,000 years ago
The area of water between Russia and North America and the Pacific and Arctic oceans is now known as the Bering Strait. Yet it was once what we call the Bering Land Bridge, an exposed land and maritime region that connected ...
Phys.org / Microplastics are chemically active and could cause biological harm
Plastics are supposed to be chemically inert. It's the reason they're used so frequently to package food, bottle water and create children's toys: They're safe. But something important happens when a large piece of plastic ...
Phys.org / AI-enhanced weather model doubles predictive power two to six weeks out
In 2021, Texas suffered the worst energy infrastructure failure in state history, following three severe winter storms in February. At least 246 people were killed as a result of the disruptions, which led to food, water, ...
Phys.org / Trailblazing technique uncovers real shape of scorching-hot exoplanet atmospheres
Until now, the alien white-hot worlds of exoplanets have been depicted as circular, but new research has revealed the true shape of their atmospheres to be a deformed sphere rather than a perfect circle.
Phys.org / Fine particles from aircraft exhaust become more harmful over time, lab tests suggest
Fine particulate matter consists of tiny particles with diameters in the nanometer range. They are produced, for example, by fuel combustion, remain suspended in the air and can penetrate deep into the respiratory tract. ...
Phys.org / From spin wave to superconducting circuit: A one-way street for quantum information
Quantum information systems could one day shape everyday life through faster computing, sharper sensing and more secure communication. A new result from the U.S. Department of Energy's (DOE) Argonne National Laboratory and ...
Phys.org / Earth's mantle was 'breathing' oxygen a billion years before it hit the atmosphere, mineral time capsules reveal
Why is there life on Earth? It's one of the oldest questions humans have asked, and as far as we know, our planet is the only one that holds the answer.
Phys.org / Satellites accurately detect methane emissions in largest controlled test yet
Researchers have conducted the largest-ever controlled test of space-based methane monitoring, finding that dedicated methane sensors correctly detected nearly all methane plumes released on clear days.
Phys.org / The stubby legs of ancient sled dogs helped people traverse the Arctic for the past 9,000 years
For centuries, dogs have helped people travel across the Arctic, hauling supplies, equipment and other goods through snowy landscapes where other domesticated animals struggled to venture. Now, a new study publishing Oct. ...
Phys.org / Warmer climate could reshape hurricane risk and its relationship with El Niño around Hawai'i
A new study examining how tropical cyclone activity near Hawai'i could change in a warmer future finds a shift toward stronger storms, even though substantial uncertainty remains about whether the total number of storms near ...
Phys.org / Urbanization takes a bigger toll on bird diversity in the tropics than it does at other latitudes, study finds
Researchers at McGill University have found that urbanization is weakening one of Earth's most enduring ecological patterns: the tendency for biodiversity to increase toward the tropics, a pattern known as the latitudinal ...
Phys.org / Most marine protected areas fail to curb fishing: Study
Fishing is increasing in most marine reserves worldwide in spite of conservation pledges, a study published Wednesday found.
