Phys.org / Rare 309-million-year-old fossils suggest early tetrapods developed without tadpole phase
Scientists have long posited that the earliest water animals to transition to land had amphibious tadpole features, going through a metamorphosis akin to that of today's frogs.
Phys.org / A new net-membrane could clean up some tricky space debris
We've reported on all kinds of wacky ideas for capturing and deorbiting space debris safely. From electric tethers to lasers, engineers and scientists have been trying everything they can think of to deal with the ever-increasing ...
Phys.org / A young gull's mottled brown plumage acts as a 'not a threat' signal to territorial adults
Birds are known for their distinctive plumage that helps them attract mates during the breeding season. For some birds, the path to adulthood is quite linear. One day they are chicks, and a few months later they are fully ...
Medical Xpress / Full-fat dairy shows benefits without raising body fat or cholesterol, study finds
A Canadian study led by University of Toronto researcher Harvey Anderson is offering new evidence in support of consuming full-fat dairy. The findings, published recently in the Journal of Nutrition, demonstrate that three ...
Phys.org / Astronomers spot an extremely rare galaxy mega-merger
Scale in the universe is hard to understand from a purely human perspective. Many times, the math just doesn't sit well with our brains, which evolved to capture and process data about the world around us rather than grok ...
Phys.org / The square kilometer array will revolutionize the hunt for alien life
With new technologies come new opportunities. And that is especially true in astronomy—with every new advanced telescope, we have the potential to see (or in some cases, listen) farther and more clearly than ever before. ...
Phys.org / Antarctic ozone loss drove unexpected Southern Ocean cooling, climate model shows
The Southern Ocean has long stood out as an oddity in the global climate system. While most of the planet's surface oceans have warmed in response to rising greenhouse gases, waters circling Antarctica showed an unexpected ...
Phys.org / Bringing rice back to Hawaiʻi: Japanese cultivars yield high-quality grains in just three months
In a major step toward enhancing food security and exploring the potential to bring rice farming back to Hawaiʻi, an international research team has successfully cultivated premium Japanese rice varieties on Kauaʻi using ...
Phys.org / Record fireworks display choked Washington in toxic smoke
The U.S. capital, Washington, saw its worst air quality of the year over the July 4 weekend, as smoke from a massive fireworks display sent pollution soaring to levels considered very unhealthy for the entire public, data ...
Phys.org / High levels of forever chemicals found on wastewater filters
As cities across the nation and the globe increasingly turn to advanced water purification systems to expand their drinking water supplies, researchers at Texas A&M University have identified a critical environmental safety ...
Phys.org / Rats show empathy, according to model
A rat first frees a cagemate rat and then shares food with it. Is this animal just as empathetic as humans? In an American study from 2011, researchers observed that rats first freed their fellow rats from a cage and then ...
Tech Xplore / AI-powered social media can subtly manipulate opinion at scale
AI tools used to generate, edit or contextualize social media posts can introduce hidden biases that spread through online networks and shape public opinion, according to new research from the Oxford Internet Institute (OII) ...
