Science retracts NASA arsenic bacteria paper after years of controversy

In 2010, in the waters of Mono Lake in California, NASA-funded scientists claimed to have found a microbe called GFAJ-1 they said rewrote biology. It had allegedly replaced the phosphorus in its DNA with the toxic element arsenic. The announcement, made at a high-profile press conference on December 2 that year, stunned the world. The…

Bacterial cell walls could hold clues to better human health, say CCMB scientists

Bacteria are enclosed by protective cell walls, made from a unique substance called peptidoglycan. This material is absent in other life forms, including humans, which is why many antibiotics target it. A team of scientists led by Manjula Reddy at CSIR-Centre for Cellular and Molecular Biology (CCMB), Hyderabad, has found that bacteria sometimes make mistakes…

Consilient evidence links lack of vitamin D to neurodevelopmental issues

From bones to immune cells, vitamin D is everywhere, guiding growth and shaping defence. But could it also have an effect on the mind? A major new study suggests so. Published in The Lancet Psychiatry, the study drew from the extraordinary depth of Danish health data to establish whether neonatal vitamin D levels might contribute…

Trump’s Golden Dome looks for alternatives to Elon Musk’s SpaceX

The U.S. Trump administration is expanding its search for partners to build the Golden Dome missile defense system, courting Amazon.com’s Project Kuiper and big defence contractors as tensions with Elon Musk threaten SpaceX’s dominance in the program, according to three sources familiar with the matter. The shift marks a strategic pivot away from reliance on…
