Sixty-six million years ago, at the end of the Cretaceous Period, an asteroid impact near the Yucat n Peninsula of Mexico triggered the extinction of all known non-bird dinosaurs. But for the early ancestors of today's waterfowl, surviving that mass extinction event was like ... water off a duck's back. Location matters, as Antarctica may
A scientist has discovered a hopping treasure trove -- 16 new species of grasshoppers living in the thorny scrubs of U.S. and Mexican deserts.

Based on the current pledges of countries for limiting their emissions of greenhouse gases, global temperatures are projected to reach 2.7 degrees Celsius beyond pre-industrial levels by the end of this century. A new review paper highlights how this would dramatically reshape the Arctic, the fastest-warming region of Earth. In 2024, annual average global air

New, groundbreaking research shows how, at a local scale, agricultural research and development led to improved crop varieties that resulted in global benefits to the environment and food system sustainability.

Researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split apart from the nautilus on the evolutionary tree. That makes it one of the oldest known animal sex chromosomes. The finding also is evidence that octopuses and other cephalopods, a
New work offers insight into how early life adapted from a low-oxygen atmosphere to the one that exists today. In a new publication in the journal Nature Communications, Montana State University scientists in College of Agriculture highlight fresh knowledge of how ancient microorganisms adapted from a low-oxygen prehistoric environment to the one that exists today.
A new study has estimated it would cost $15.6 billion per year for 30 years to prevent extinction for 99 of Australia's priority species. The research highlights the urgent need for increased funding to combat threats such as habitat destruction, invasive species and climate change. A new study has estimated it would cost $15.6 billion
A new international study highlights the severity of climate change impacts across African mountains, how farmers are adapting, and the barriers they face -- findings relevant to people living in mountain regions around the world.

Detailed study of a Greenland glacier's flow rate reveals the impact of environmental conditions. Even though 'glacial' is commonly used to describe extremely slow, steady movement, a new study has found that glaciers speed up and slow down on a daily -- even hourly -- basis in response to changes in air temperature, rainfall and
Honey bee mortality can be significantly reduced by ensuring that treatments for the parasitic Varroa mite occur within specific timeframes, a new study reveals.

A recent study has uncovered compelling evidence suggesting that the climate effects of new particles in urban areas have been significantly underestimated. Particles play a crucial role in climate regulation, influencing processes such as cloud formation and radiation balance. Traditionally, research in urban environments has focused largely on primary particles -- those directly emitted from
More crevasse activity could lead to positive feedback loop threatening Greenland glacier's stability. In just five years, 930 million cubic meters of crevasses opened up in the Greenland ice sheet, equivalent to adding a crack the size of the Great Pyramid of Giza to the world's second largest ice sheet every few days. The increased
Rice cultivation is responsible for around 12% of global methane emissions, and these emissions are expected to increase with global warming and as the human population continues to grow. Now, scientists have identified chemical compounds released by rice roots that determine how much methane the plants emit. They report that this information enabled them to
A 13th-century fresco rediscovered in Ferrara, Italy, provides unique evidence of medieval churches using Islamic tents to conceal their high altars. The 700-year-old fresco is thought to be the only surviving image of its kind, offering precious evidence of a little-known Christian practice.
