Summary: Researchers analyzed longitudinal data from thousands of preteen girls and found that testosterone—often viewed as primarily a male hormone—plays a prominent and previously underappreciated role in early emotional vulnerability among girls aged 10 to 12. The study shows that internal neurochemical fluctuations are stronger predictors of anxiety and depression than visible physical changes, highlighting … Read more

Summary: Unveiled at the Alzheimer’s Association International Conference in London, the Consortium for Biomedical Research and Artificial Intelligence in Neurodegeneration (C-BRAIN) has released three open-source AI platforms. Designed as a collaborative “AI Biomedical Research Scientist,” these tools analyze global neuroscience literature, surface insights hidden in unpublished or negative results (so-called “dark data”), and offer structured … Read more

Summary: Researchers recorded real-time brain activity in infants and adults while they listened to speakers in different noisy settings. The team found that, even with an immature cerebral cortex, human infants can use spatial separation cues early in life to pick out and follow a single speaker in a crowded auditory scene. Key Facts Early … Read more

Summary: Researchers analyzed decades of socioeconomic data by linking national medical registries with detailed tax records. They found that people who later receive an early-onset dementia diagnosis experience substantial and steadily worsening work productivity losses that begin years before clinical diagnosis. The timing and magnitude of these losses differ by underlying pathology. Key Facts The … Read more

Summary: Drawing on hundreds of studies in psychology, behavioral economics and neuroscience, researchers show that procrastination is a complex psychological struggle rooted in an evolutionary mismatch in the brain. Rather than a single habit, procrastination takes multiple forms. The research identifies nine distinct procrastinator profiles and presents a practical toolkit to address the specific mental … Read more

Summary: Engineers have created a new cerebellum-inspired electronic chip that detects unexpected events while consuming very little power. Unlike most neuromorphic efforts that model the cerebrum (the brain’s thinking center), this device emulates the cerebellum’s reflex-driven strategy: it ignores predictable background signals and activates only for novel, surprising inputs. In trials using electrocardiogram (ECG) data, … Read more

Summary: Researchers have shown that axon formation is an autonomous, internally driven process. Young neurons use an internal protein complex to systematically loosen their own cytoskeletal scaffold from the inside out, establishing the early wiring of the nervous system through an intrinsic genetic program. Key Facts The Intrinsic Control Shift: Instead of relying primarily on … Read more

Summary: New research using simultaneous EEG and fMRI demonstrates that the human brain does not run a single unified process. Instead, the connectome coordinates multiple independent, asynchronous streams of information processing that run in parallel. This finding alters how researchers interpret fMRI and EEG signals and opens new possibilities for clinical neuro-diagnostics and studies of … Read more

Summary: An international team of paleontologists has identified the earliest known example of population-level “handedness” in the animal kingdom. By analyzing more than 100 exceptionally preserved fossils of the Ediacaran organism Spriggina floundersi, researchers found a consistent, population-wide bias for bending to the right in life. These results indicate that lateralized behavior—and by implication, asymmetry … Read more

Summary: Researchers have shown that BA-101, an experimental compound, can strip away a key defensive mechanism used by glioblastoma. By selectively inhibiting the neuronal nitric oxide synthase (nNOS) enzyme that drives excessive nitric oxide production, BA-101 dismantles the tumor’s nitrosative stress shield. In preclinical models this restores sensitivity to temozolomide, slows tumor growth, and promotes … Read more
