A new European Southern Observatory (ESO) study has found that current proposals to launch over 1.7 million satellites into orbit, including extremely bright ones, would have “devastating consequences for astronomy.” According to the study, no more than 100 000 faint satellites, below naked eye visibility, should…
All along the South African coast you find dolosse wherever coastal management is necessary to prevent tides and rough seas from eroding breakwaters, harbour walls, coastal construction. In Port El…
You gather your most expensive people into a room to make your most important decisions. Then, somewhere in the second hour, the room quietly gets worse at making them. Not the people. The room.
Carpenter ants amputate the injured legs of fellow ants to minimise the risk of infection. A new study involving a Würzburg researcher shows that this task is primarily carried out by ants switching from indoor to outdoor duties.
The world’s tallest tropical trees have no trouble pumping water to their topmost branches, new research reveals. Conventional scientific theory suggests that as trees grow, it becomes harder to transport water from roots to leaves
Every spring, as sure as the seasons, and for generations unknown, screwworms began their annual march northward from their overwintering sanctuaries in Mexico and South Texas.
On building Mr. Baby Paint, a radically simple co-op drawing app for toddlers & accidentally discovering a flood-fill cellular automata, plus developing pixel-fattening algorithms for bitmap fonts.
Comprehensive review brings together global evidence to strengthen public trust and counter misinformation as mRNA vaccines expand to prevent and treat more diseases.
Study finds that healthy but sedentary individuals show early decline in cellular energy production.
A single intravenous dose of Ewingella americana achieved complete tumor elimination in 100% of treated animals, with no detectable toxicity—outperforming chemotherapy and immunotherapy.
A look inside the biology, engineering, and validation behind a major scientific milestone.
On July 1, 2026, arXiv will spin out from Cornell University, its home for the past 25 years, to become an independent nonprofit organization. With this next…
Last year, we introduced Brain2Qwerty v1, research that uses AI to decode brain activity into text without any surgical implant. Now we're sharing the next step: Brain2Qwerty v2, the highest-performing end-to-end pipeline capable of real-time sentence decoding from non-invasive brain recordings, approaching levels of…
Equations governing dynamics and control of a multirotor UAV
According to a new analysis by Stanford Medicine scientists, changing clocks twice a year disrupts circadian rhythms, leading to higher rates of stroke and obesity.
Today, the Large Hadron Collider ( LHC ), the world’s most powerful particle accelerator, comes to the end of an extraordinary chapter in its scientific journey. Following its final physics run , the accelerator has been switched off to begin CERN’s Long Shutdown 3 (LS3), a major programme of maintenance…
The California Science Center has begun the complex process of moving components into place for space shuttle Endeavour’s awe-inspiring vertical display.
The most detailed vascular image of a living human brain we've seen, captured with ultrasound through the skull — and the pipeline behind it.
Hiking with Wallace, my 6" f/2.8 corrected dobsonian.
PHerc. 1667, sealed since the eruption of Vesuvius in 79 AD, has been virtually unwrapped and read from beginning to end — without ever being opened.
IBM unveiled a major semiconductor breakthrough with the introduction of the world’s first sub-1 nanometer (nm) chip technology, featuring a revolutionary transistor architecture at the 0.7 nm, or 7 angstrom node.
Introducing Intercept, a $500M bet to make respiratory infections like colds and flu a thing of the past.
Some skepticism of vitamin D skepticism
I ran a pairwise-choice experiment on my Greyhound to rank his favorite treats, measure side bias, and accidentally turn bedtime snacks into a statistics problem.
Get ready to scroll. In 2017, Wollaton Hall in Nottinghamshire hosted an exhibition, Dinosaurs Of China: Ground Shakers To Feathered Flyers. Wollaton Hall Curator Adam Smith arranged for the SVPCA …
Some connections between things, which I have not seen elsewhere. Maybe they mean something?
Every once in a while the internet gets talking about Geometric Algebra (henceforth GA) and how it’s a new theory of math that fixes everything that’s wrong with linear algebra and multivariable calculus. When I come across this stance I am compelled to respond with something like: “wait wait, it’s not true! GA is…
An atlas of the vibrance of the real world
Samsung Electronics' Semiconductor Research Center presented the paper “First Demonstration of 3D Stacked FETs at Gate Pitch of 42 nm Featuring Triple Stacked Nanosheet Channels for Advanced Logic Applications” at the 2026 VLSI Symposium, held from June 14–18.
