Antarctica gained 695 billion tons in 2021-23 as tropical warmth drove heavy snowfall
Between 2021 and 2023, Antarctica experienced a notable gain in ice mass, primarily driven by exceptional snowfall in East Antarctica. This unusual occurrence, influenced by warmer tropical ocean temperatures, caused atmospheric disturbances that transported moisture southward. Although this gain temporarily countered ongoing ice loss in other regions, it does not signify a change in Antarctica's long-term trend of declining ice mass.
Scientists seeded clouds over China’s Muz Taw Glacier; fresh snow cut ice loss by 14% to 17%
Scientists tested cloud seeding over China’s Muz Taw Glacier in 2018 to create artificial snowfall and slow ice loss. The experiment used silver iodide generators to encourage snow formation. Researchers found that fresh snow made the glacier surface brighter and reduced the amount of ice lost over a short period. However, they said the results are preliminary and need further testing.
Meet Dr Alberto Cruz: The palaeontologist who found an Ice Age toad in a La Brea fossil
A new extinct spadefoot toad species, Spea labreae, was identified from ancient fossils. Dr. Alberto Cruz discovered the unusual bone while studying collections at La Brea Tar Pits. This finding adds to the limited fossil record of Ice Age amphibians in North America. The toad's presence offers new insights into ancient Los Angeles' environmental history. Researchers also found evidence of a Mexican burrowing toad in the same region.
Why do elephants visit the same graves? The fascinating mystery behind their behaviour
In a remarkable display of emotion, elephants often demonstrate a keen interest in the remains of their own kind, revisiting and examining skeletal structures with their trunks. Studies reveal that this behavior occurs even when the carcasses are not fresh, leading researchers to ponder if it signifies a sense of loss or an instinct for knowledge gathering. Nonetheless, the idea of elephant graveyards is considered largely a legend.
1,800 years ago, a Roman household decorated floor with cat and dog; archaeologists uncover mosaic
Archaeologists in Turkey have uncovered a colourful Roman-era mosaic dating back around 1,800 years. Found inside a villa at ancient Adramytteion, the mosaic features 15 panels showing animals and mythological figures. Two animals are named in Greek: a cat called Emerald and a dog called Ocean.
As El Niño intensifies, scientists in Chile are making a vulnerable penguin species wear copper vests, here's why
In an inspiring initiative, Chilean researchers are designing specialized vests for injured penguins, incorporating copper and zinc to expedite healing. This groundbreaking effort is focused on supporting the struggling Humboldt penguin population by preventing further injury while enhancing recovery. The vests draw on effective treatments that have proven successful for domestic animals, showcasing a creative blend of technology and compassion.
In 1980, conservationists began eradicating feral sheep to restore California's Santa Cruz Island
Conservationists undertook a significant effort to remove feral sheep from Santa Cruz Island, aiming to revive its delicate ecosystem. Over seven years, thousands of these sheep were eliminated, risking the extinction of a unique heritage breed. To counter this, twelve lambs were rescued to spearhead a captive breeding initiative on the mainland, ensuring the preservation of a rare genetic lineage and honoring California's rich agricultural heritage.
Hidden gut bacteria populations linked to ageing, cancer and type 2 diabetes may spread worldwide
Scientists led by the University of Vienna have found hidden populations within common gut bacteria, some of which are linked to ageing, colorectal cancer, inflammatory bowel disease and type 2 diabetes. The study also found evidence that certain bacterial populations can spread between people and across continents within a few decades, suggesting the gut microbiome may be more transmissible and dynamic than previously thought.
Man hid inside a Roman storage jar 1,600 years ago; archaeologists uncover his final moments
Archaeologists have unearthed the skeletal remains of a man tucked inside a massive Roman storage jar, offering a chilling glimpse into the past. It appears he sought refuge from a violent raid, as evidenced by the surrounding destruction and signs of fire. Two iron knives discovered alongside him imply a desperate act of self-defense. This city's fate remained enigmatic for an astonishing sixteen centuries before it was eventually rebuilt.
Indian startup unveils testing & manufacturing hubs to validate reusable rocket stages
Indian space startup Agnikul Cosmos inaugurated two new facilities in Chennai. These facilities will support testing and manufacturing of reusable rocket stages. The company aims to develop reusable launch vehicle technology for future missions. Agnikul Cosmos already designs and manufactures its own rocket engines. This expansion marks a significant step in India's space program capabilities.
