A new study reports that autism is linked to two opposing molecular patterns in the brain, suggesting distinct biological signatures rather than a single underlying profile. Researchers say the findings could help explain the wide variation in how autism presents and point toward more targeted avenues for future research. Coverage of the study is drawing attention from scientists and readers following developments in neuroscience and autism research.

New research suggests that weight regained after dieting may be driven by brain biology rather than simply a lack of willpower, pointing to neural mechanisms that push the body back toward its previous weight after a diet ends. The findings are being discussed as a possible shift in how obesity and dieting failure are understood, with implications for treatment and public attitudes toward weight loss.

Researchers report a surprising connection between bone density and brain aging, according to a new study covered by SciTechDaily. The finding suggests skeletal health may be tied to how the brain ages, a link that could shape future research into dementia and osteoporosis. Science commentators are sharing the study, with many noting it challenges the usual separation between bone and brain research.

New research highlights a paradox in REM sleep: the brain's fuel supply appears to rise during dreaming, yet energy is still being drained. Scientists suggest that the intense neural activity behind vivid dreams may consume more energy than the increased supply can offset. The findings could reshape understanding of why sleep is restorative and how dreaming supports brain function.

Slime molds, single-celled organisms with no brain, have become the focus of a heated scientific debate after showing abilities like solving mazes and optimizing networks. Researchers disagree over whether such behaviour counts as genuine intelligence or merely simple chemical processes, with the dispute touching on broader questions about how intelligence should be defined in biology.

Slime molds—single-celled organisms with no brain—are once again at the centre of a scientific debate about intelligence. The organisms can solve mazes, optimise networks and remember without neurons, leading researchers to argue over whether such behaviour counts as genuine cognition or merely sophisticated chemistry. The dispute touches on how broadly science should define intelligence and whether it requires a nervous system at all.
