- 1Immigration rules pushing foreign scientists out of the U.S.●Immigration changes are driving foreign researchers to leave the U.S.
Foreign researchers are leaving the United States as immigration policy changes make it harder for them to stay and work. The report, based on a survey of scientists, points to visa uncertainty and tougher residency procedures as key factors. Commenters worry the exodus will weaken American science and drive talent to other countries competing for researchers.
- 2Favorite music still reaches the brain in dementia▼The brain still responds to favorite music in dementia
New research reported by Medical Xpress shows that the brains of people with dementia continue to respond to their favorite music. The findings suggest musical memories may be preserved even as other cognitive functions decline, offering potential for music-based therapies and improved quality of care for patients.
- 3Autism Study Finds Two Opposing Molecular Brain Patterns▼Autism Study Reveals Two Opposing Molecular Patterns in the Brain
A new autism study has identified two opposing molecular patterns in the brain, suggesting the condition may involve distinct biological signatures rather than a single shared profile. The findings point to different molecular pathways that appear to work in opposite directions, which could help explain the wide variability in autism and guide more targeted research into its underlying biology.
- 4Weight regain after dieting may be driven by brain biology▼Weight regain after dieting may be driven by brain biology, research finds
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.
- 5REM sleep paradox: dreaming may drain brain energy▼REM sleep paradox: Dreaming may drain the brain’s energy even as fuel supply rises
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.
- 6Slime Molds Ignite Debate Over What Counts as Intelligence▼Slime Molds and the Growing Science Controversy Around “Intelligence”
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.
