Feb 18th 2025, 20:37

Meeting the minimum requirement for vitamin B12, needed to make DNA, red blood cells and nerve tissue, may not actually be enough -- particularly if you are older. It may even put you at risk for cognitive impairment.

Feb 18th 2025, 17:44

Researchers used mice with nine different genetic backgrounds to identify factors influencing eye aging, paving the way for eye-based diagnostics for neurodegenerative diseases.

Feb 18th 2025, 15:33

A sponge-like implant in mice helped guide a treatment that slowed or stopped a degenerative condition similar to multiple sclerosis in humans. It also gave researchers a look at how primary progressive multiple sclerosis, the fastest-progressing version of the disease, attacks the central nervous system early on.

Feb 18th 2025, 14:59

Confidence. Persistence. Ingenuity. Conventional wisdom tells us these are some of the traits needed for success at the office. But within teams, less laudable characteristics -- maintaining the status quo, for instance -- might be just as desirable, according to new research. An expert on organizational thinking reports that teams with high rates of envy often ostracize their best performers, in turn leading those standout employees to sabotage productivity.

Feb 18th 2025, 14:59

A groundbreaking study has revealed a surprising biochemical connection between plant immune responses and human neurological health. Researchers have discovered that the metabolic pathways regulating vitamin B6 homeostasis -- critical in certain forms of epilepsy and immune function -- are shared by plants and humans.

Feb 18th 2025, 11:40

A newly identified part of a brain circuit mixes sensory information, memories, and emotions to tell whether things are familiar or new, and important or just 'background noise.'

Feb 18th 2025, 11:38

How much does the evolution of human speech owe to one amino acid?

Feb 18th 2025, 11:36

New research adds evidence that learning a successful strategy for approaching a task doesn't prevent further exploration, even if it reduces performance.

Feb 17th 2025, 13:34

Scientists have developed a geometric deep learning method that can create a coherent picture of neuronal population activity during cognitive and motor tasks across experimental subjects and conditions.

Feb 17th 2025, 13:34

Scientists have developed a lipid nanoparticle system capable of delivering messenger RNA (mRNA) to the brain via intravenous injection, a challenge that has long been limited by the protective nature of the blood-brain barrier. The findings demonstrate the potential of this technology to pave the way for future treatments for a wide range of conditions such as Alzheimer's disease, amyotrophic lateral sclerosis, brain cancer, and drug addiction.
