Lately, I’ve been really into 3D printing along with asking myself what we can do with this technology now that it’s become, well, a technology. (At least, in the “this is a thing that can now be used, is robust, and is generally accessible to many people” sense of technology.) The first thing to print on a 3D printer…
Scientists have found the first direct evidence of the powerful role our genetic makeup plays in influencing our risk of cancer, with inherited genes interacting with acquired genetic mutations to shape how tumours evolve.
Scientists have uncovered how tobacco plants naturally make nicotine, solving a mystery that has puzzled researchers for nearly two centuries.

Blood is pumped from the heart through arteries to the hoof and is assisted in its return through a “pumping mechanism” in the hoof. This mechanism is necessary due to the position of the hoof in relation to the heart. There are no muscles in the lower leg or hoof to aid in the return of venous blood to the heart…
You might already know that atoms are mostly empty space. Physical size behaves a bit weirdly at the atomic scale, but essentially the radius of an atom’s nucleus is tens of thousands of times smal…

New research from the University of St Andrews and Université de Neuchâtel, has uncovered the mechanism which allows sperm whales to sleep in a unique vertical position, just under the ocean surface.
We asked an internal research Claude model to design minibinders (small proteins that attach tightly to a target) against scorpion neurotoxins.
A benchmark for evaluating AI agents on research workflows across scientific domains
Pushing affordable marine conservation forward with autonomous marine robots powered by Raspberry Pi Compute Module 4.
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.
If you live in a major city, I can take a pretty good guess at one of your most common frustrations: traffic. In city driving, the journey is rarely better than the destination. In most cases, we just want to get where we’re going. Traffic is not just frustrating, but it has consequences to the envi
Hopkins engineers have created robots the size of a pencil tip intended to travel through the body to deliver medicine to infections inside a beating heart

I was inspired by Tom Scott’s excellent video and links here where he talks about a particular type of “Inogon” light used to guide ships through channels or harbours. The patent …
SLAC scientists observed an immune signaling complex forming inside cells for the first time, revealing insights that could guide new treatments.
The team is the first to directly observe a unique property in an altermagnetic candidate material, key evidence of a new phase of magnetism.
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.
David Gruber wants to know what sperm whales are saying. He thinks it might actually be possible.
A new Northwestern University study in humans and mice has discovered a novel biomarker of schizophrenia that could also serve as a new drug candidate to treat the cognitive symptoms of the disorder. Schizophrenia affects .5% of the world’s population, including about two million people in the U.S.
New study by Emanuela Campisi (University of Catania) and Anita Slominska and Asli Ozyurek (Max Planck Institute for Psycholinguistics) reveals that Italian and Dutch adults adapt their hand gestures in remarkably similar ways when explaining new concepts to children.
CU Boulder researchers have developed 3D-printable materials embedded with living bioluminescent algae that can produce sustained light.

Potential sleep solutions like “pink noise” & other ambient noises worsened sleep quality, while earplugs protected sleep, in a study on the effects of aircraft noise on sleep.
