In 1987, four years after the discovery of HIV as the causative agent of AIDS, scientists reported the first drug effective against the virus, called zidovudine. Zidovudine targeted a viral enzyme called reverse transcriptase, and prevented the virus from completing its life-cycle. However, zidovudine was no magic bullet. It could hold the virus at bay…

Hand preference reflects how the brain organises movement control | Photo Credit: Kelly Sikkema/Unsplash — Gayatri Chandrashekar A: There’s a neural basis for handedness but it’s not due to any single part of the brain. Hand preference reflects how the brain organises movement control. In most right-handed people, the left hemisphere has stronger control over…

“Scientists have long known that emotional states such as stress and anxiety can influence the intensity of these sensations. While the neural mechanisms linking stress and pain have been studied extensively, the effect of stress on itch has remained poorly understood,” IISc said.

In many animals, sex is decided by obvious physical differences in the chromosomes. But in ants, bees, and wasps, sex is often decided in a more unusual way: by whether an embryo carries two different versions of a specific DNA region or two matching ones. Two studies, one in Science Advances in 2024 and the…

Chicks, like humans, often match “bouba” with round shapes and “kiki” with spiky ones. | Photo Credit: Michael Anfang/Unsplash Scientists find bouba-kiki effect in three-day chicks Humans often match “bouba” with round shapes and “kiki” with spiky ones. Researchers raised baby chicks, then played the sounds while showing them the two shapes. Three-day-old chicks chose…

In a 1953 experiment, two scientists named Stanley Miller and Harold Urey attempted to recreate the conditions of the early earth long before life existed. They showed that organic molecules such as amino acids, the building blocks of proteins, could form spontaneously in the conditions that prevailed on a primitive earth, 3.5-4 billion years ago….

A group of quantum researchers has issued a manifesto urging colleagues to resist what it calls the “militarisation” of quantum science. The authors, who describe themselves as “Quantum Scientists for Disarmament”, say they oppose military uses of quantum research, reject military funding for academic work, and want universities to disclose which quantum projects take defence…

For decades, fluorescent proteins have been among the most powerful tools in biology. They glow when illuminated, allowing scientists to see where molecules are inside cells and how they move. From tracking cancer cells to mapping neural circuits, these luminous markers transformed the life sciences, work recognised with a Nobel Prize in 2008. Now, two…
