[ad_1] Something unusual has been going on in the wild. Many members of the largest species of dolphins, commonly called killer whales (Orcinus orca), have been found sharing freshly killed prey with humans. And they don’t just offer their prey: the dolphins have waited for the humans to respond. In a new study reported in

[ad_1] Rising seas are a major consequence of global warming, with many implications for low-lying coastal areas. Coral reefs, which are highly sensitive to their environment, are also particularly vulnerable to fluctuations in sea level. When the sea level rises, sunlight may no longer penetrate the water to reach a coral reef that it could

[ad_1] A labelled diagram of the human pelvis. | Photo Credit: Public domain Walking on two legs is the single most distinctive trait that separates humans from other primates. Unlike apes, our pelvis is short, broad, and bowl-shaped, and thus stable for walking upright while supporting internal organs and holding space to deliver large-headed infants.

Changes

[ad_1] Plastic is cheap, versatile, and used almost everywhere, from packaging and textiles to medical supplies. But unlike natural materials, plastic doesn’t simply decay; instead, it breaks down into smaller fragments called microplastics (<5 mm) and nanoplastics (<1 µm). These particles persist for decades or longer, accumulate in water bodies, and attract other pollutants like

These particles are so small and light that they are easily

[ad_1] Odonatologists have reconfirmed the presence of the elusive dragonfly species, Crocothemis erythraea, in the high-elevation regions of the southern Western Ghats. The species had previously been misidentified or overlooked in this region due to its close resemblance to the more widespread lowland species, Crocothemis servilia. The genus Crocothemis in India includes two known species—C.

[ad_1] CSIR-Centre for Cellular and Molecular Biology scientists have discovered a novel method to accelerate tissue repair and regeneration. This discovery opens a new frontier in cell biology, with significant implications for regenerative medicine and cancer biology. Led by Santosh Chauhan, the scientists showed that cells have a built-in way to revive from the brink

[ad_1] When the Delhi High Court ordered internet service providers to block access to Sci-Hub and its mirrors, it closed a chapter in one of the more fraught debates in contemporary research: who gets to read research papers, and who must pay. The verdict followed years of litigation by Elsevier, Wiley, and the American Chemical

Physics of staying airborne When the engines of this aeroplane were removed, heavy winds were able to tilt it backwards. This is because the centre of gravity in its body shifted to the rear.
