Astronomers from the Chinese Academy of Sciences (CAS) have employed the Lijiang 2.4-m telescope to perform optical photometric and spectroscopic observations of a core-collapse Type IIP supernova designated SN 2024abfl. ...
Phys.org / Back-to-back Amazon droughts trigger record forest stress
Two back-to-back droughts in 2023 and 2024 caused the most severe decline in forest moisture and biomass (the total mass of living vegetation such as leaves, trunks and branches) in the Amazon since 1992, according to a study ...
Phys.org / Using menstrual blood-derived particles to treat osteoarthritis
New research by an interdisciplinary team in Lithuania has revealed a promising and unconventional approach to cartilage regeneration. Using extracellular vesicles derived from menstrual blood stromal cells, the researchers ...
Phys.org / Unlocking Earth's 4.5-billion-year secret: The case of the missing lead
Geoscientists have long relied on different forms of lead to understand Earth's geological history and how it was created over billions of years. However, there is a mystery that has been puzzling scientists for decades: ...
Phys.org / Glaciers rapidly declining, with extreme losses in 2025
Earth's glaciers are continuing to shrink at alarming rates, with new international research revealing that 2025 was among the worst years on record for global ice loss. Published in the Climate Chronicles collection of Nature ...
Phys.org / SoCal's hybrid bees outsmart Varroa mites before they even hatch
Southern California is home to a flying black-and-yellow treasure. While commercial honeybee hives nationwide are collapsing under attack from deadly parasites, a unique hybrid bee found only in this part of the state has ...
