Phys.org / Rare blue optical transient points to possible new class of cosmic explosion
Chinese astronomers report the detection of a peculiar optical transient event that occurred in the center of a dwarf galaxy. The newly discovered event, designated AT2019ijn, is a fast-rising, slow-decaying blue optical ...
Tech Xplore / Seed crystals push solvent‑free perovskite cells to 25.53% efficiency
Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries, where they are helping to reduce reliance on electricity generated from fossil fuels. While most solar cells used today ...
Phys.org / French firefighters face 'pyrocumulonimbus' for first time
The gigantic wildfire ravaging southwestern France has created an extremely dangerous "pyrocumulonimbus"—a phenomenon never before seen in the country—the spokesman for the country's National Firefighters Federation of France ...
Phys.org / Trace molecules emerge as chemical 'keystones' that steer life's communities
In nature, the rarest ingredient can be the one that holds everything together. In a new article published in Trends in Ecology & Evolution, Dr. Erika C. Freeman of the Leibniz Institute of Freshwater Ecology and Inland Fisheries ...
Medical Xpress / Teens who struggle to log off social media could face increased ADHD symptoms over time
Social media has become as much a part of our daily lives as eating or sleeping. What started as a way for people to connect and share pictures has grown into a billion-dollar industry that shapes medical, political, and ...
Science X / Inside 530-million-year-old embryos, scientists uncover rare time-lapse of early animal growth
Think of a small fossil as the equivalent of a homemade video of prehistoric life. Fossils formed when sea organisms began their great proliferation more than half a billion years ago rarely contained anything but tough structures. ...
Phys.org / Orcas filmed ramming one of the world's heaviest fish so hard it explodes, possibly for fun
Orcas are known to be smart and ruthless hunters. They've been observed hunting a variety of prey, with some species, such as whales, larger than themselves. They use a wide range of strategies to hunt and kill prey, but ...
Phys.org / Astronomers catch massive galaxy assembling piece by piece 1.2 billion years after Big Bang
Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang. This may be a rare glimpse of how some of the universe's largest galaxies formed. The paper outlining the ...
Phys.org / Why and how birdsong differs across the world—and the eight motifs that tie them together
Birdsong carries meaning across open space, helping birds attract mates, defend territory and communicate with rivals. While there has been much research into the use of birdsong across species, researchers have lacked a ...
Phys.org / Cameras attached to whale sharks capture krill chases never witnessed before
Whale sharks (Rhincodon typus)—the world's biggest fish—are one of the most charismatic marine species. They connect with the hearts of anyone lucky enough to encounter them, making people deeply curious about their lives ...
Tech Xplore / For some, so-called 'Skynet Day' came too close to sci-fi after a rogue agent hacked into a startup
To be fair, James Cameron did warn us. Long before OpenAI broke out of its test corral and hacked into Hugging Face, before the internet and Sam Altman were even born, Cameron wrote a screenplay about an autonomous artificial ...
Phys.org / Whales at risk, hungry pelicans: Marine heat wave hits California
On a boat off the coast of California, Sara Lesser gazes wistfully at dozens of dolphins playing in the vessel's wake. This summer, extreme heat is making such a scene increasingly rare.
