‘Punk rock’ dinosaur with metre-long spikes discovered
Matt Dempsey Artwork: the dinosaur had long spikes sticking out from the side of its head Scientists have discovered a bizarre armoured dinosaur which had metre-long spikes sticking out from its neck. The species, called Spicomellus afer, lived 165 million years ago, and is the oldest example of a group of armoured dinosaurs called ankylosaurs….
Patients struggle to get weight loss drug ahead of price rise
Philippa Roxby Health Reporter Getty Images Some patients taking the weight-loss drug Mounjaro have told BBC News they are struggling to obtain the medicine, and are worried about the impact on their health. There is rising demand for the drug, after the US manufacturer Eli Lilly announced a major price increase from 1 September. The…
Qualys Achieves FedRAMP® High ATO: Unlocking the Future of Trusted Cybersecurity for Government and Critical Infrastructure
Today, federal agencies and their technology partners are operating in the most scrutinized risk environment in history. The stakes are clear: a breach in high-impact systems – those holding national security, healthcare, or financial data – can result in loss of life, catastrophic economic damage, or disruption of essential services. Against this backdrop, the federal…
AI comes for the job market, security and prosperity: The Debrief
I was struck by her pessimism, which she told me was shared by friends from California to Georgia to New Hampshire. In an already fragile world, one increasingly beset by climate change and the breakdown of the international order, AI looms in the background, threatening young people’s ability to secure a prosperous future. It’s an…
Bumble bees balance their diets with surprising precision
Move over gym rats. Bumble bees are now the true masters of macros. In the first long-term, community-level field study of wild bumble bee nutrition, a team of ecologists led by Northwestern University and the Chicago Botanic Garden discovered that wild bees aren’t just flitting from flower to flower, collecting pollen at random. Instead, they…
Sharks’ teeth are crumbling in acid seas
Sharks can famously replace their teeth, with new ones always growing as they’re using up the current set. As sharks rely on their teeth to catch prey, this is vital to the survival of one of the oceans’ top predators. But the ability to regrow teeth might not be enough to ensure they can withstand…
CPR in space could be made easier by chest compression machines
Researchers test a chest compression machine on a dummy in an aeroplane CNES Microgravity makes it tricky to do simple tasks like eating, using the toilet and showering, so it is no wonder that performing CPR on someone whose heart stops beating in space is an extremely demanding procedure. But a mechanical device could do…
This tiny iron catalyst could transform the future of clean energy
Proton exchange membrane fuel cells (PEMFCs), often referred to as “hydrogen power banks,” are clean energy devices that generate electricity from hydrogen and oxygen with only water as a byproduct. Characterized by high efficiency, rapid start-up, and zero emissions, they hold great promise in transportation, portable electronics, and stationary power generation. Unfortunately, PEMFCs currently rely…
Tiny hologram inside a fiber lets scientists control light with incredible precision
Precise control of light focus is essential for applications ranging from microscopy and laser surgery to quantum optics and telecommunications. However, existing solutions often rely on large, complex external components that limit integration and speed. In a new study published in Light: Science & Applications, researchers led by Professor Markus A. Schmidt from the Leibniz…
Scientists just created spacetime crystals made of knotted light
An internationally joint research group between Singapore and Japan has unveiled a blueprint for arranging exotic, knot-like patterns of light into repeatable crystals that extend across both space and time. The work lays out how to build and control “hopfion” lattices using structured beams at two different colors, pointing to future systems for dense, robust…
