More than half of men and millions of women are affected by hair loss. It causes low self-esteem in some and anxiety in others. Thankfully, scientists around the world are getting to the roots of the problem with pioneering new treatments.
Scientists report that a new class of magnetism, called altermagnetism, can increase memory device operation speeds by up to a thousand times.
On September 20, as part of the TRIADS Speaker Series, philosopher David Chalmers will visit WashU to pose a seemingly straightforward question: “Can ChatGPT Think?”
While Chalmers isn’t in the business of providing a direct “yes” or “no” answer to philosophical quandaries like these, he’s perhaps one of the best-qualified minds to ask the question and unravel its potential implications. Whether in the form of books or TED Talks, Chalmers has grappled with the nature of human consciousness for the better part of three decades. And on a parallel track, he has kept a close eye on the development of artificial intelligence, penning journal articles on the subject and presenting at AI conferences since the early ’90s.
Chalmers, now a New York University Professor of Philosophy and Director of the NYU Center for Mind, Brain, and Consciousness, met via Zoom to discuss the marvels and mysteries of ChatGPT, how he uses philosophical questions to gauge the progress of large language models, and his two years spent at Washington University as a postdoctoral fellow.
A quantum experiment suggests time may not be fixed. Photons appeared to react before being hit, challenging classical physics and opening debates on time’s true nature.
Argentine scientists created the world’s first genetically edited horse using CRISPR-Cas9 technology. Next projects include gene editing in pigs and cows.
Psychologists call it the dark triad: an intersection of three of the most malevolent tendencies of human nature – psychopathy, narcissism, and Machiavellianism.
But the truth goes deeper, and darker. There’s also egoism, sadism, spitefulness, and more. And behind this rogues gallery of all our worst inclinations on the surface, a central, common core of human darkness lies, researchers say.
In a 2018 study, psychologists from Germany and Denmark mapped this driving force behind all our darkest impulses and gave it a name. Meet D, the newly identified Dark Factor of Personality.

Synthetically replicating transmembrane protein signal transduction is a gaol of synthetic biology. Here, the authors show how the dimerization of synthetic transmembrane DNA receptors can be used to engineer sensing and actuation cascades in response to external molecular signals.
All genomes are replicated in a temporal order, though the determinants of such timing are poorly characterized. Here, the authors show that the unusual chromosome size-dependent DNA replication timing in Leishmania is influenced by RNA-DNA hybrids that are recognised by the endonuclease RNase H1.
