Randomness is incredibly useful. People often draw straws, throw dice or flip coins to make fair choices. Random numbers can enable auditors to make completely unbiased selections. Randomness is also key in security; if a p***word or code is an unguessable string of numbers, it’s harder to crack. Many of our cryptographic systems today use Continue Reading
How do you intuitively know that you can walk on a footpath and swim in a lake? Researchers from the University of Amsterdam have discovered unique brain activations that reflect how we can move our bodies through an environment. The study not only sheds new light on how the human brain works, but also shows Continue Reading
Insulin resistance detected by routine triglyceride-glucose (TyG) index can flag people with early Alzheimer’s who are four times more likely to present rapid cognitive decline, according to new research presented at the European Academy of Neurology (EAN) Congress 2025.1 Neurologists at the University of Brescia reviewed records for 315 non-diabetic patients with cognitive deficits, including Continue Reading

The raids targeted Iran’s uranium-enrichment Continue Reading
There’s no two ways about it: tardigrades are badblock. These eight-legged, microscopic water-dwellers have survived the vacuum of space, extreme dehydration, and temperatures ranging from near absolute zero to above boiling point. In 2021, researchers fired frozen tardigrades from a gun onto a target several metres away, to simulate a meteorite impact, and showed that Continue Reading

Obesity drugs might reduce pressure inside the skull, relieving migraines.Credit: LordHenriVoton/Getty Head-splitting migraines could be the next ailment in a seemingly endless list that a cl*** of blockbuster weight-loss drugs might treat. In a small study, the drug liraglutide reduced monthly migraine episodes by nearly half among people with obesity who experience the headache-inducing condition. Continue Reading
“This photograph, taken in February, captured the first return of the light to the world’s most northerly permanent settlement, Ny-Ålesund, on the Arctic archipelago of Svalbard, Norway. I have been working in Svalbard for more than a decade, studying the microbial life in this extreme place. The surfaces of its glaciers, for example, are colonized Continue Reading
AMPA-type ionotropic glutamate receptors (AMPARs) are integral to fast excitatory synaptic transmission and play vital roles in synaptic plasticity, motor coordination, learning, and memory1. While extensive structural studies have been conducted on recombinant AMPARs and native calcium impermeable (CI)-AMPARs alongside their auxiliary proteins2-5, the molecular architecture of native calcium permeable (CP)-AMPARs has remained undefined. To Continue Reading
Nature’s Memory: Behind the Scenes at the World’s Natural History Museums Jack Ashby Allen Lane (2025) Natural history museums are crucial for conservation — and for communicating its importance to the public. But step through the ‘staff only’ doors, and museums look very different. In vaults and laboratories, curators store, catalogue and preserve millions of Continue Reading
