Particle physicists may have found a particle made purely of force, mammals were giving live birth 60 million years earlier than thought, and Ozempic inadvertently revealed how the brain handles craving.
Physicists report compelling evidence for a particle composed entirely of gluons — the force-carriers of the strong nuclear force. Theoretical models predicted glueballs for decades; confirmation required reanalysing data from the BESIII detector in Beijing.
Analysis of a 225-million-year-old fossil from what is now Argentina shows soft-tissue evidence consistent with live birth, pushing back the origin of viviparity in the mammal lineage by roughly six decades of evolutionary time.
A computational analysis of ribosomal RNA evolution suggests the universal common ancestor was not a single lineage but that life arose at least twice, with two early populations later merging via horizontal gene transfer.
Neuroimaging studies of GLP-1 receptor agonist users show that weight-loss drugs suppress a previously undercharacterised region involved in motivational salience. Researchers say the finding opens new targets for addiction and compulsive behaviour.
An MIT team using fMRI and intracranial EEG found that complex logical reasoning activates regions distinct from those used in language processing, challenging the assumption that inner speech is necessary for abstract thought.
A research group released a pre-print demonstrating that a language model fine-tuned on virology literature can design novel viral sequences with functional properties — prompting immediate calls for publication controls and oversight frameworks.
