Phys.org / Ammonites survived asteroid impact that killed off dinosaurs, new evidence suggests
In the aftermath of the giant asteroid that crashed into the Yucatan Peninsula about 66 million years ago, approximately 75% of all species on Earth were wiped out, including the dinosaurs. Among those thought to have perished ...
Phys.org / Greenland's Prudhoe Dome ice cap was completely gone only 7,000 years ago, study finds
The first study from GreenDrill—a project co-led by the University at Buffalo to collect rocks and sediment buried beneath the Greenland Ice Sheet—has found that the Prudhoe Dome ice cap was completely gone approximately ...
Phys.org / Making the invisible visible: Space particles become observable through handheld invention
You can't see, feel, hear, taste or smell them, but tiny particles from space are constantly raining down on us.
Phys.org / Vulnerable populations shoulder larger number and higher intensity of environmental burdens, study finds
Vulnerable communities in the United States often face the highest risks from individual environmental burdens, such as exposure to toxic air pollutants. But new research shows that these communities are also exposed to a ...
Phys.org / Betelgeuse's elusive companion star: Siwarha's 'wake' detected
Using new observations from NASA's Hubble Space Telescope and ground-based observatories, astronomers have tracked the influence of a recently discovered companion star, Siwarha, on the gas around Betelgeuse. The research, ...
Phys.org / Climate adaptation has a new global plan. What the Belem indicators are and why they matter to Africa
At the 2025 global climate summit, COP30, held in Belém, Brazil, one decision stood out with major consequences for Africa: countries agreed on a new set of progress indicators.
Phys.org / Climate messaging sways minds, not wallets, regardless of political party
In a study involving more than 13,000 participants in the U.S., several messaging strategies were shown to move the needle—albeit slightly—in attempts to strengthen pro-environmental attitudes and behaviors regarding ...
Phys.org / Biological pumps: How zooplankton are transporting microplastics to the ocean depths
A new study has, for the first time, recorded and measured just how fast microplastics move through the gut passage of a key zooplankton species in real time—and used those measurements to estimate how much plastic these ...
Phys.org / The US used to be really dirty: Environmental cleanup laws have made a huge difference
Growing up in the 1970s, I took for granted the trash piles along the highway, tires washed up on beaches, and smog fouling city air. The famed "Crying Indian" commercial of 1971 became a symbol of widespread environmental ...
Phys.org / EPA says it will propose drinking water limit for perchlorate, but only because court ordered it
The Environmental Protection Agency on Monday said it would propose a drinking water limit for perchlorate, a harmful chemical in rockets and other explosives, but also said doing so wouldn't significantly benefit public ...
Phys.org / Scientists solve the mystery of Europe's missing dinosaurs. Spoiler alert! They were never actually missing
Ceratopsians were horned, beaked dinosaurs that once stomped their way all over North America and Asia during the Late Cretaceous period, about 80 million years ago. Their abundance in the fossil records of these continents, ...
Phys.org / The 'Age of Fishes' began with mass death, fossil database reveals
Some 445 million years ago, life on Earth was forever changed. During the geological blink of an eye, glaciers formed over the supercontinent Gondwana, drying out many of the vast, shallow seas like a sponge and giving an ...
