Five people have been found trapped in a flooded cave in Laos. How will divers get them out?
Five people have been found trapped in a flooded cave in Laos, with rescue efforts now focusing on extraction. The operation is complicated by low oxygen supplies, dark and narrow spaces, and ongoing rainfall.
How bacteria survive with almost no oxygen— and why blocking one enzyme could aid new antibiotics
Researchers in Leiden have, for the first time, observed how a specialized enzyme helps bacteria stay alive when oxygen levels are low, and how that process can be blocked. The study, published in Science Advances, opens up new possibilities for targeted antibiotics.
Zorawar tank: The made-in-India war machine built to dominate China on the LAC
The rollout of the Zorawar light tank from the AM Naik Heavy Engineering Complex marked a watershed moment for India’s defence industry. Developed in just 19 months, it is the country’s first indigenous light tank designed for high‑altitude warfare in the Himalayas. Zorawar was conceived during the tensions with China along the Line of Actual Control and as a counter to the Type 15 tanks the Indian Army faced during the stand-off.
New study has shone a new light on searching for habitable worlds
New study has shone a new light on searching for habitable worlds Sadie Harley Scientific Editor Andrew Zinin Lead Editor When astronomers discovered the first planet outside our solar system, it was orbiting a pulsar, one of the most extreme, radiation-blasted environments imaginable. Not exactly the kind of place you'd expect to find a planet, let alone a representative one. The first confirmed exoplanet was an oddity, a product of the fact that pulsar timing is extraordinarily sensitive,...
Why the Arctic's rivers are rusting now and where toxic orange water could spread next
Why the Arctic's rivers are rusting now and where toxic orange water could spread next Sadie Harley Scientific Editor Robert Egan Associate Editor Scientists have identified the two biggest reasons that once-pristine rivers across the Arctic are growing cloudy with toxic orange iron particles that smother insects and suffocate fish. A new study published in Communications Earth & Environment builds on earlier research documenting widespread contamination in Alaska's Brooks Range. As the...

Basis for a hands free blood flow measurement with automated vessel focus
arXiv:2510.11060v2 Announce Type: replace Abstract: Cardiopulmonary resuscitation (CPR) is an essential tool to ensure oxygen supply during cardiac arrest, yet not quantifiable to this day. Low-quality chest compressions or wrong pressure placement go unnoticed. This paper presents a solution for the quantification of blood flow to guide first responders in their efforts.
'Astonishing': James Webb telescope spots the most chemically primitive galaxy in the ancient universe
'Astonishing': James Webb telescope spots the most chemically primitive galaxy in the ancient universe The James Webb telescope peered into an ancient spot of light, and found it to be the most metal-poor galaxy in the early universe. One of the greatest achievements of the James Webb Space Telescope is how it has allowed scientists to push the boundaries of astronomy by observing galaxies that existed during the early universe, less than 1 billion years after the Big Bang. This period,...
