SpaceX’s xAI to compete in Pentagon contest for autonomous drone technology
SpaceX, xAI and the Pentagon’s defense innovation unit did not immediately respond to requests for comment. | Photo Credit: REUTERS Elon Musk’s SpaceX and its wholly-owned subsidiary xAI are competing in a secret new Pentagon contest to produce voice-controlled, autonomous drone swarming technology, Bloomberg News reported on Monday, citing people familiar with the matter. SpaceX,…

Who wins the science prize when AI makes the discovery?
In 1974, Antony Hewish won the physics Nobel Prize for discovering pulsars. His graduate student, Jocelyn Bell Burnell, had actually spotted the first one in the data; she’d also built parts of the telescope herself, analysed the charts, noticed the anomaly, and helped confirm that it was real. But she didn’t win the prize. At…

Lean into the abyss: the counterintuitive beauty of skiing
Every instinct tells you to lean back. You’re standing at the top of a slope that drops away beneath you like the edge of the world, and every fibre of your being screams to press your weight into the mountain behind you. To hold on. To stay safe. And that’s exactly how you fall. Something…

How district cooling can ease India’s climate and urban planning troubles
With rising temperatures, longer heatwaves, and a rapidly growing urban economy, cooling in India is rapidly shifting from a lifestyle choice to a basic need, driving up air-conditioner use in homes and workplaces. This surge is now a major part of cities’ power demand, in turn raising concerns about blackouts and higher emissions and about…

Loggerhead turtles face four-pronged threats due to climate change
Scientists noticed that loggerhead turtles are getting smaller in size, reducing their reproductive output: smaller females produce smaller clutch sizes. | Photo Credit: Brian Gratwicke (CC BY) The spectre of climate change has come to haunt one of the ocean’s most ubiquitous — yet vulnerable — turtles: the strong-jawed loggerhead, named after its exceptionally large head. These omnivorous marine reptiles have been…

Anxiety is faced by 58 genetic variants, not single gene, says study
Clarifying the influence of genetic factors that increase the risk of experiencing clinical anxiety may, in the future, help us to identify people who are particularly vulnerable |Image used for representational purpose only | Photo Credit: DrAfter123 Researchers have found 58 genetic variants linked to an increased risk of anxiety, suggesting that the disorder is…

Single genome-editing strategy promises to treat multiple disorders
Genetic disorders often stem from small errors in the DNA sequence with major consequences. Many diseases like cystic fibrosis and Batten disease can be traced to changes disrupting the cell’s ability to build a complete, functional protein. One particularly common culprit is the nonsense mutation, where a single incorrect DNA letter inserts a premature stop…

Bridging a divide with an ‘Indian Scientific Service’
India’s post-Independence service rules were designed to ensure stability through generalist administrators — an approach that was essential for nation-building. However, governance has since become increasingly shaped by science, technology, and environmental challenges. As scientists joined government service, they remained governed by rules created for a different era. This mismatch has limited the effective integration…
