Stroboscopic light therapy started in the lab, detoured through wellness culture, and arrived somewhere genuinely interesting. 💡 I tested it out on myself – from consumer products to lab grade therapies. My verdict? It might be worth a try... sciencefocus.com/news/a-bizar...

Anthropic says its new AI model found thousands of critical security flaws — including some in every major OS and browser — and is too dangerous to release publicly. So what happens when someone else builds the same thing? And do we really need to be worried? www.sciencefocus.com/news/interne...

Long-term cryosleep and reawakening may no longer be completely in the realm of science fiction 🧪 Researchers froze mouse brain tissue and restored its function once thawed. Still a long way from entire organisms, let alone people, but sooo cool, right? www.sciencefocus.com/news/cryogen...

Astronauts in cryosleep is one of science fiction's most enduring fantasies – but a new study suggests the gap between fiction and reality just got a little smaller

Yes, the world can be bleak at times. But it really ain't all bad. This story of tortoises returning to a Galapagos island after 180 yrs brought a smile to my face this morning. 🐢 Pretty interesting science behind this too 🧪 www.galapagos.org/newsroom/gib...

New dinosaur alert 🦖 🧪 🚨] Palaeontologists have discovered a new species of dinosaur in a remote part of the Sahara. Named Spinosaurus mirabilis – meaning ‘astonishing’ Spinosaurus in Latin – the giant lived in what is now Niger more than 95 million years ago. www.sciencefocus.com/news/new-din...

A global analysis has found river deltas - some of the most densely populated areas on Earth - are sinking, often faster than sea level rise. 🧪 For those living in deltas, sea ⬆️ or land ⬇️ makes little difference, but it does change what you can do about it... www.sciencefocus.com/news/deltas-...

Why sinking cities may now be a bigger climate crisis than rising seas | BBC Science Focus Magazine

A hidden force is causing highly populated river deltas to sink. In many cases, the subsidence is happening faster than the sea is rising

Scientists just put 7k sodium atoms into a superposition (quantum effect where something is at different locations at same time). This raises the possibility of doing the same to viruses or even proteins. Mind sufficiently blown? Please continue w/ ur day 🧪 www.nature.com/articles/d41...

Schrödinger’s cat just got bigger: quantum physicists create largest ever ‘superposition’

Record-breaking experiment shows that a cluster of thousands of atoms can act like a wave as well as a particle.

EU's deforestation delayed again, with possibly more delays and legislative changes again this year. 🌳🌲 Is this a lesson for lobbyists to never give up, even after a law is passed? Seems to be working... 😐 trellis.net/article/euro...?

Europe’s anti-deforestation law is delayed again. What's to come

The landmark regulation has been simplified — or weakened, depending on whom you ask — with more uncertainty ahead in the new year.

Humans (likely Neanderthals) were making fire 350,000 years earlier than we thought. 🔥 🧪 Remnants of an ancient campfire were found in a field in England of all places. 🏴󠁧󠁢󠁥󠁮󠁧󠁿 “The implications are enormous,” said Dr Rob Davis of the British Museum. www.theguardian.com/science/2025...

This wasn't on my bingo card for 2025. Bryan Johnson live-streamed a psilocybin trip this week, with special guests including a set from the DJ Grimes. 🍄 Can't tell whether this is brilliant or totally dystopian... techcrunch.com/2025/12/02/t...

A diverse range of mammals once roamed the planet. This changed dramatically with the arrival of humans, who have become the dominant species through our own population, as well as the animals we breed and raise for food. What is the distribution of the global mammal kingdom today?

The visual representation illustrates the global biomass of various animal groups, emphasizing the dominance of humans and livestock. Humans constitute 36% of total biomass, depicted by a grouping of figures representing people. Livestock and pets collectively make up 59% of biomass, represented below humans.

Within the livestock category, cattle are noted as the largest contributors at 38%, followed by sheep at 4%, buffalo at 6%, and goats and pigs, both at 3%. Horses, asses, and dogs each account for 3% and 2% respectively. 

Wild mammals, positioned at the bottom, represent only 5% of total biomass, illustrated by animal figures. 

The footer includes data sourced from Lior Greenspoon et al. in 2023, regarding the global biomass of wild mammals as published in the Proceedings of the National Academy of Sciences. The organization, Our World in Data, is credited for its role in providing research and data pertaining to global issues.

A controversial study has claimed to have caught a glimpse of dark matter... Yes, actual dark matter! 🧪 ⚛️ “It would mark the first time humanity has ‘seen’ dark matter,” the study's author said. Yet, others say it’s far from the definitive answer... here's why: www.sciencefocus.com/news/dark-ma...

A 'superflare' 10 trillion X brighter than the Sun has been confirmed as the most luminous burst of light ever from a black hole. 🧪 ⚛️ What caused such an outburst? Astronomers think a star, >30X the Sun's mass, was being gobbled up by the BH. ⚫ A light snack? www.nature.com/articles/d41...
