Brunt Ice Shelf in Antarctica calves new iceberg
A large iceberg (380 km2), about the size of the Isle of Wight, has broken off the 150m-thick Brunt Ice Shelf. It broke off after a crack suddenly appeared in the ice shelf a few weeks ago. The final break happened in the early hours of Monday, 20 Ma.....»»
Male southern elephant seals are picky eaters, study suggests
As one of the top predators roaming Antarctica, the sizeable southern elephant seal has its fair selection of the menu. But it turns out they don't just want to eat anything and everything......»»
Avian influenza has killed millions of seabirds around the world: Antarctica could be next
Antarctica is often imagined as the last untouched wilderness. Unfortunately, avian influenza ("bird flu") is encroaching on the icy continent. The virus has already reached the sub-Antarctic islands between the Antarctic Peninsula and South America......»»
Can seabirds hear their way across the ocean? Our research suggests so
Animals cover astonishing distances when they are looking for food. While caribou, reindeer and wolves clock up impressive mileage on land, seabirds are unrivaled in their traveling distances. Arctic terns travel from the Arctic to Antarctica and bac.....»»
People once lived in a vast region in north-western Australia—and it had an inland sea
For much of the 65,000 years of Australia's human history, the now-submerged northwest continental shelf connected the Kimberley and western Arnhem Land. This vast, habitable realm covered nearly 390,000 square kilometers, an area one-and-a-half time.....»»
Antarctic octopus DNA reveals ice sheet collapse closer than thought
Scientists investigating how Antarctica's ice sheets retreated in the deep past have turned to an innovative approach: studying the genes of octopuses that live in its chilly waters......»»
Mineral coatings could enable shelf-stable mRNA therapies
A protective mineral coating identified by University of Wisconsin–Madison biomedical engineering researchers could allow powerful messenger RNA therapeutics like COVID-19 vaccines to be stored at room temperature, making them more accessible to lo.....»»
Two recent studies expand understanding of how early social housing helps dairy calves thrive
Dairy industry professionals continuously work to ensure the highest possible welfare for dairy calves, including fine-tuning their housing to improve overall health, well-being, and performance. Two new studies in JDS Communications are illuminating.....»»
NASA"s GUSTO prepares to map space between the stars
On a vast ice sheet in Antarctica, scientists and engineers are preparing a NASA experiment called GUSTO to explore the universe on a balloon. GUSTO will launch from the Ross Ice Shelf, near the U.S. National Science Foundation's McMurdo Station rese.....»»
Antarctic krill head south: Scientists fear the movement will have a negative impact on predators
Some populations of Antarctic krill are shifting south, closer to Antarctica, as ocean warming and sea-ice changes alter their habitat. Scientists fear the movement of krill will have a negative impact on predators like whales, seals and penguins, an.....»»
Scientists are recommending IceCube should be eight times bigger
The IceCube Neutrino Observatory, operated by the University of Wisconsin-Madison (UW-M), located at the Amundsen–Scott South Pole Station in Antarctica, is one of the most ambitious neutrino observatories in the world. Behind this observatory is t.....»»
British research ship crosses paths with world"s largest iceberg as it drifts out of Antarctica
Britain's polar research ship has crossed paths with the largest iceberg in the world—a "lucky" encounter that enabled scientists to collect seawater samples around the colossal berg as it drifts out of Antarctic waters, the British Antarctic Surve.....»»
New bottlenose dolphin sense discovered: Research suggests they can feel weak electric fields
Born tail first, bottlenose dolphin calves emerge equipped with two slender rows of whiskers along their beak-like snouts—much like the touch-sensitive whiskers of seals. But the whiskers fall out soon after birth, leaving the youngster with a seri.....»»
Dremio introduces GenAI-powered data documentation and labeling to reduce manual work
Dremio has unveiled AI-powered data discovery capabilities that accelerate and simplify data contextualization and description for analytics, along with improved capabilities that extend its leadership as the analytics engine for Apache Iceberg. Expa.....»»
Antarctica"s ancient ice sheets foreshadow dynamic changes in Earth"s future
Nineteen million years ago, during a time known as the early Miocene, massive ice sheets in Antarctica rapidly and repeatedly grew and receded. The Miocene is widely considered a potential analog for Earth's climate in the coming century, should huma.....»»
Deep-sea coral evidence found for enhanced subglacial discharge from Antarctica during meltwater pulse 1A
Subglacial discharge from the Antarctic Ice Sheet (AIS) likely played a crucial role in the loss of ice sheet and the subsequent rise in sea level during the last deglaciation. However, no direct proxy is currently available to document subglacial di.....»»
Climate engineering could slow Antarctic ice loss, study says
Scattering sunlight-reflecting particles in the atmosphere could slow rapid melting in West Antarctica and reduce the risk of catastrophic sea-level rise, according to a study led by Indiana University researchers......»»
Researchers extend shelf life of electrolyzers that can convert carbon dioxide to green chemicals
An international research team at DTU has increased the shelf life of electrolyzers that convert CO2 from half a day to 100 hours. This is good news for companies working with the process. The findings were published in Nature Catalysis under the tit.....»»
Revolutionizing strawberry production: CRISPR/Cas9 editing enhances fruit firmness and extends shelf life
The cultivated strawberry (Fragaria × ananassa, Duch.) is one of the Rosaceae family renowned for its flavor and health benefits, making it an important agricultural commodity. However, its soft texture leads to a brief shelf life and consequent eco.....»»
North Atlantic"s marine productivity may not be declining, according to new study of older ice cores
To paraphrase Mark Twain, reports of declining phytoplankton in the North Atlantic may have been greatly exaggerated. A prominent 2019 study used ice cores in Antarctica to suggest that marine productivity in the North Atlantic had declined by 10% du.....»»
Baby dolphins found to receive high doses of persistent organic pollutants from their mothers" milk
