How new fossils and modern technology are tracing the origins of snakes
Back when dinosaurs stomped the Earth, mammals scurried about in their shadows. Those furballs, hiding in underground burrows, provided a fresh niche for a novel reptile: the snake. Skinny snakes could squeeze into mammals’ holes and gobble them up. At least, that’s how the dawn of snakes is imagined by Marc Tollis, an evolutionary biologist…

Small study hints that revving up immune cells might help fight HIV
This colourised electron microscope image provided by the U.S. NIH shows a human T cell (blue) under attack by HIV (yellow). | Photo Credit: AP Scientists are tweaking a powerful cancer therapy in hopes it could fight HIV instead, by supercharging patients’ own immune cells. On May 12, researchers said a single dose of those…

Many communities have historically practised endogamy and in some regions, consanguineous marriage. This is both a social and a biological fact with medical consequences. India is not one genetic population. Indians carry a layered inheritance…

IMD unveils weather model to provide ‘block level’ forecast of monsoon journey
At the new system’s core are two forecasting models whose predictions are “blended,” to sharpen accuracy. File | Photo Credit: The Hindu Ahead of the monsoon this year, the India Meteorological Department (IMD) on Tuesday unveiled a new forecast system that will, for the first time ever, generate ‘block’ level forecasts of the monsoon’s arrival…

How do volcanoes affect the earth’s atmosphere?
The underwater volcano Hunga Tonga-Hunga Ha’apai, off Tonga, erupted powerfully in 2022. | Photo Credit: Reuters Volcanoes change the earth’s atmosphere by releasing gases and particles in large quantities. When a volcano erupts, it blasts sulphur dioxide high into the sky, which reacts with water to form aerosols. Since aerosols scatter sunlight, a powerful eruption…

Cancer immunotherapy may reshape brain’s barrier to metastasis
Drugs that enhance the body’s immune response against cancer may also be altering one of its most tightly guarded boundaries: the blood-brain barrier (BBB). A recent study published by Yuval Shaked at the Technion-Israel Institute of Technology and his team, in Cancer Discovery, finds that PD-1 inhibitors, a widely used class of cancer immunotherapy, can…
