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

Summary: Researchers have shown that breakdown of the myelin sheath—the insulating layer that surrounds nerve fibers—destabilizes brain circuits and produces distinctive sleep-only electrical abnormalities. Continuous multi-night electroencephalogram (EEG) recordings in animal models revealed epilepsy-like spikes that appear only during sleep and a marked slowing of REM sleep oscillations. These sleep-linked electrical signatures closely track myelin … Read more

Summary: A multi-institutional team reviewed medical and mortality records spanning six decades and found that former National Football League (NFL) players have markedly higher rates of death from neurodegenerative diseases than the general population. Although NFL veterans show lower overall mortality, they are about four times more likely to die from neurodegenerative conditions—including dementia and … Read more

Summary: Dartmouth researchers combined eye-tracking in virtual reality headsets with machine learning and large language models (LLMs) to show that our gaze is guided by deep, personal “conceptual priorities.” Rather than only following bright or prominent objects, people tend to seek out items that carry abstract, meaningful themes for them. These thematic viewing patterns are … Read more
