Aptitude
An aptitude is an innate inborn ability to do a certain kind of work. Aptitudes may be physical or mental. Aptitude and intelligence quotient are related, and in some ways opposite, views of human mental ability. Whereas intelligence quotient sees intelligence as being a single measurable characteristic affecting all mental ability, aptitude breaks mental ability down into many different characteristics which are supposed to be more or less independent of each other. However, a casual analysis of any group of test scores will nearly always show them to be highly correlated.

Sep. 8, 2026 Semaglutide, the drug behind Ozempic and Wegovy, may have benefits that extend well beyond weight loss and diabetes. In a large Swedish study of nearly 15,000 people with bipolar disorder, its use was linked to a 21% lower risk of psychiatric ...
Sep. 8, 2026 Starting statins soon after a type 2 diabetes diagnosis may do more than protect the heart. In a nationwide Danish study of more than 132,000 people, those who began statin treatment within a year of diagnosis had a 15% lower relative risk of ...
Sep. 6, 2026 A large study involving more than 270,000 people has linked higher blood levels of the amino acid tyrosine to a shorter lifespan in men. Using both observational data and genetic analysis, researchers found that elevated tyrosine could potentially ...
Sep. 6, 2026 Older adults at risk of dementia improved their memory and thinking after following lifestyle programs combining exercise, healthy eating, cognitive training, and social engagement. Those who received regular coaching and structured support improved ...
Sep. 6, 2026 Researchers may have found a new way to weaken glioblastoma’s defenses against treatment. Blocking a protein called SET prevented tumors from forming in preclinical models, while targeting related proteins made cancer cells more vulnerable to ...
Sep. 4, 2026 A substance found in edible sea squirts appeared to reverse several signs of aging in older mice. Plasmalogen supplements improved memory and learning, strengthened connections between brain cells, reduced inflammation, and even helped the mice grow ...
Sep. 4, 2026 UCLA researchers have discovered two powerful influences that help guide how the human brain forms before birth. Radial glia, stem cells responsible for producing much of the cerebral cortex, change their behavior depending on how they process ...
Sep. 3, 2026 Duke researchers developed an injectable scaffold that helped stroke-damaged brains grow new blood vessels, support nerve regrowth, and recover movement in mice. The treatment appears to work partly by recruiting the body’s own immune cells, ...
Sep. 3, 2026 Aging may be partly fueled by immune cells losing their ability to clear away damaged, inflammation-promoting cells. Blocking a single receptor restored that cleanup process in mice, reducing inflammation and helping their organs, muscles, and ...
Sep. 2, 2026 Some of the attention patterns that make ADHD challenging may also help spark creativity by allowing the brain to explore more ideas and unexpected connections. Researchers think creative activities could potentially channel this “defocused ...
Sep. 2, 2026 Brain changes associated with Alzheimer’s may begin at least seven years before amyloid plaques become detectable with current PET scans. Researchers uncovered the signal by tracking healthy older adults with repeated brain imaging over nearly 20 ...
Sep. 1, 2026 Mindfulness, gratitude, and optimism training may improve blood pressure, inflammation, and other heart-health measures within just eight to 12 weeks. The strongest programs paired daily practice with regular reinforcement, suggesting that improving ...
