The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Unveiling the Role of EVs in Bacterial Communication and Immune Surveillance

Messenger bubbles produced by human cells can pick up bacterial products and deliver them to other cells, University of Connecticut researchers report in the Nov. 16 issue of Nature Cell Biology.

New Tool Tracks Mouse Movements and Brain Activity

Mice exhibit constant activity, regardless of external stimuli such as the presence of a nearby cat. Their ongoing actions, which include whisker movement, environmental exploration, and self-grooming, trigger neural responses spanning various brain regions.

Artificial System Develops Key Characteristics Similar to Human Brains Under Physical Constraints

Cambridge scientists have shown that placing physical constraints on an artificially-intelligent system – in much the same way that the human brain has to develop and operate within physical and biological constraints – allows it to develop features of the brains of complex organisms in order to solve tasks.

More Genes Changed By Early Life Stress Than Head Injury

Researchers recently discovered a phenomenon as they delved into the investigation of whether early-life stress exacerbates the impact of a childhood head injury on health and behavior in later years.

Circular Extrachromosomal DNA Linked to Medulloblastoma Relapse and Death

A study of newly created databases of medulloblastoma has found that patients with tumors containing circular extrachromosomal DNA-;loops of DNA found outside of regular chromosomes-;are twice as likely to relapse and three times as likely to die within five years of diagnosis.

Rare Genetic Variant Found to Protect Against Alzheimer's Disease

Researchers at Gladstone Institutes have discovered that a rare genetic variant known as the "Christchurch mutation" can block detrimental effects of apolipoprotein E4, the best-established risk factor for the most common form of Alzheimer's disease.

New Drug-Like Molecule Enhances Mitophagy, Protects Against Neurodegeneration

Having healthy mitochondria, the organelles that produce energy in all our cells, usually portends a long healthy life whether in humans or in C. elegans, a tiny, short-lived nematode worm often used to study the aging process.

New Study Sheds Light on Evolution of Sex Differences in Animals

Researchers at the Francis Crick Institute and Heidelberg University in Germany have shown that sex differences in animals vary dramatically across species, organs and developmental stages, and evolve quickly at the gene level but slowly at the cell type level.
