Polar Bears That Persist
A new subpopulation of Greenland polar bears offers insights into how this species might hang on as Arctic ice disappears......»»
Pollen diaries: Polar ice records preserve climate vs. human impact following Little Ice Age
Pollen can help scientists track changes in vegetation through time, as they respond to moderations of the climate, be that glaciation or deglaciation with transitions into and out of ice ages. Furthermore, it can help elucidate the interplay between.....»»
Glacier melting destroys important climate data archive
As part of the Ice Memory initiative, Paul Scherrer Institute (PSI) researchers, with colleagues from the University of Fribourg and Ca' Foscari University of Venice as well as the Institute of Polar Sciences of the Italian National Research Council.....»»
Novel graph neural network models enhance precipitation forecasting
In the AI era, pure data-driven meteorological and climate models are gradually catching up with and even surpassing traditional numerical models. However, significant challenges persist in current deep learning models, such as low physical consisten.....»»
Why the Polar Vortex Is Bad for Balloon Artists

Study finds bigfoot sightings correlate with black bear populations
The big conclusion: "If bigfoot is there, it could be a bear." Enlarge / Black bears will frequently stand on their hind legs, which may increase their misidentification. (credit: Wirestock) The idea that North America.....»»
Molecular sensor enables water bear hardiness by triggering dormancy, study finds
Tardigrades—hardy, microscopic animals commonly known as "water bears"—use a molecular sensor that detects harmful conditions in their environment, telling them when to go dormant and when to resume normal life. A team led by Derrick R. J. Kollin.....»»
First polar bear to die of bird flu: What are the implications?
Climate change is a threat to polar bear's survival. Now they have a new deadly challenge facing them: bird flu. It was recently confirmed that a polar bear from northern Alaska has died from the disease......»»
Black bear removed from North Lake Tahoe home after trying to hibernate in crawl space

The first assessment of toxic heavy metal pollution in the Southern Hemisphere over the last 2,000 years
Human activity, from burning fossil fuels and fireplaces to the contaminated dust produced by mining, alters Earth's atmosphere in countless ways. Records of these impacts over time are preserved in everlasting polar ice that serves as a sort of time.....»»
When polar bears hunt snow geese, hunger justifies the means
Polar bears (Ursus maritimus) take advantage of the winter to build up their fat reserves. Intensive hunting of seals, a resource rich in fat, allows bears to store up enough energy to get through the summer......»»
New research on microbes expands the known limits for life on Earth and beyond
New research led by Stanford University scientists predicts life can persist in extremely salty environments, beyond the limit previously thought possible......»»
Bottled water can contain hundreds of thousands of previously uncounted tiny plastic bits, study finds
In recent years, there has been rising concern that tiny particles known as microplastics are showing up basically everywhere on Earth, from polar ice to soil, drinking water and food. Formed when plastics break down into progressively smaller bits,.....»»
Battling persistence in tuberculosis bacteria
Researchers at the Indian Institute of Science (IISc), in collaboration with NCBS and InStem, have uncovered an important mechanism that allows the tuberculosis (TB) bacterium to persist in the human host for decades. They found that a single gene in.....»»

Dogs, antennas and honey for Japan"s big bear problem
Thousands of bears are being shot in Japan each year as they become more and more of a problem. Junpei Tanaka and his dog Rela, straining at her leash in the woods, have a kinder, smarter way......»»
Permafrost: A ticking time bomb beneath our feet
Nearly a quarter of the Earth's land surface is permanently frozen. These areas, known as permafrost, are found in northern polar regions and at high altitudes. But the permafrost is now starting to thaw—with potentially disastrous consequences for.....»»
Mollusks from polar expeditions reveal new details about the ocean
In the early hours of 30 October 1961, a Russian bomber took off and flew north. The plane was headed for the Novaya Zemlya archipelago in the Russian part of the Arctic. When the pilot saw the islands far below, he released the cargo—a bomb the si.....»»
Image: Ice flows on Mars
On Aug. 18, 2023, the Mars Reconnaissance Orbiter (MRO) captured ridged lines carved onto Mars' landscape by the gradual movement of ice. While surface ice deposits are mostly limited to Mars' polar caps, these patterns appear in many non-polar Marti.....»»
Webb rings in holidays with ringed planet Uranus
The James Webb Space Telescope recently trained its sights on unusual and enigmatic Uranus, an ice giant that spins on its side. Webb captured this dynamic world with rings, moons, storms, and other atmospheric features—including a seasonal polar c.....»»
Challenging assumptions: The 8.5-year rhythm of Earth"s inner core
Researchers from China have confirmed the existence of an approximately 8.5-year Inner Core Wobble (ICW) in both polar motion and length-of-day variations, revealing a static tilt of about 0.17 degrees between the Earth's inner core and mantle, chall.....»»
