Secrets to how humans lost their tails revealed: a groundbreaking journey stemming from curiosity and leading to discovery.
A study in Nature Human Behaviour characterizes protein signatures in the blood associated with social isolation and loneliness, demonstrating how these link social isolation and loneliness to an increased risk of disease and mortality.

Shen et al. characterize protein signatures in the blood associated with social isolation and loneliness, demonstrating how these link social isolation and loneliness to an increased risk of disease and mortality.
The brain’s response to emotional words is guided by neurotransmitters like dopamine and serotonin, shaping how we interpret language. Surprising new research shows even the thalamus is involved, bridging emotion and cognition.
Summary: Researchers have uncovered how neurotransmitters in the brain respond to the emotional content of language, shedding light on the intersection of emotion, cognition, and communication. Using advanced techniques, the team simultaneously measured dopamine, serotonin, and norepinephrine release in patients during exposure to emotionally charged words.

Fuel-cell technology is set to take a step forward as chemists have created a triple-headed metallic nanoparticle, FePtAu, which generates higher current per unit of mass than any other nanoparticle catalyst tested. In tests, researchers from Brown University found that the FePtAu catalyst reached 2809.9 mA/mg Pt and after 13 hours has a mass activity of 2600mA/mg Pt, or 93 percent of its original performance value.
Advances in fuel-cell technology have been stymied by the inadequacy of metals studied as catalysts. The drawback to platinum, other than cost, is that it absorbs carbon monoxide in reactions involving fuel cells powered by organic materials like formic acid.
Any substance that when dissolved in water, gives a pH less than 7.0, or donates a hydrogen ion.
Neuralink Corp.’s brain-computer device has been implanted in a third patient and the company has plans for about 20 to 30 more implants in 2025, founder Elon Musk said.
“We’ve got now three humans with Neuralinks implanted and they’re all working well,” Musk said during an event in Las Vegas this week that was streamed on X, his social media service.
Neuralink is one of a growing group of startups developing brain implants that can help treat conditions such as paralysis and ALS. They are experimental procedures that usually require opening up the skull to place electrodes in the brain tissue. A year ago, Neuralink said it had implanted its device in its initial patient, Noland Arbaugh.
Pierre de was a French lawyer and government official most remembered for his work in number theory; in particular for’s Last Theorem. He is also important in the foundations of the calculus.
A man was arrested on suspicion of purposely starting a brush fire in Azusa, police announced.
First responders were called to Pioneer Park shortly after 11:30 p.m. on Friday, according to the Azusa Police Department. There, a witness told officers the man who ignited the blaze was still at the scene.
A Yale-led project that aims to develop quantum technology into practical applications has been awarded a prestigious grant from the National Science Foundation (NSF).
Erasure Qubits and Dynamic Circuits for Quantum Advantage (ERASE), a pilot project led by Yale physicist Steven Girvin, is a collaboration between academia and an industrial hardware partner, Quantum Circuits, Inc. (QCI), a Connecticut-based company that aims to bring to market the first practical quantum computers.
In the early 20th century, the mathematician Godel showed that any mathematical system is incomplete, using a version of the self-referential paradox: ‘this sentence is not true’. Here, neuroscientist and philosopher, Erik Hoel, argues this incompleteness extends to the scientific project as a whole; in part due to science’s reliance on mathematics. More radically, Hoel argues, this incompleteness of science may account for why we can’t find scientific evidence for consciousness anywhere in the world.
Let’s say you lived in a universe where you really were some sort of incarnated soul in a corporeal body. Or some sort of agent from a vaster reality embedded in a simulation (depending on definitions, the two scenarios might not be that different). What would the science in such a dualistic universe look like?
