Pathologists' examinations of tissue samples from skin cancer tumors improved when they were assisted by an AI tool. The assessments became more consistent and patients' prognoses were described more accurately. This is shown by a study led by Karolinska Institutet, conducted in collaboration with researchers from Yale University.

Hearing loss doesn't just affect how people hear the world—it can also change how they connect with it.

Alzheimer's disease (AD) is a common, debilitating neurodegenerative disease affecting about 10% of people over the age of 65 and one third of people aged 85 and above. Besides environmental factors, the genes have a strong influence on whether or not a person develops AD during their lifetime.

"Forever chemicals" or per- and polyfluoroalkyl substances (PFAS) have been widely used in consumer and industrial products for the better part of a century, but do not break down in the natural environment. One PFAS, perfluorohexanoic acid or PFHxA, is made up of a shorter chain of molecules and is thought to have less of an impact on human health.

Oral nicotine pouches—small, smokeless, nearly invisible and placed between the lip and gum—are rapidly gaining popularity among teens, sparking new concerns from public health experts.

New research from UC Davis Comprehensive Cancer Center has uncovered an evolutionary change that may explain why certain immune cells in humans are less effective at fighting solid tumors compared to non-human primates. This insight could lead to more powerful cancer treatments.

Sudden infant death syndrome (SIDS) is the unexpected, unexplained, sudden death of a child younger than one year old. Although the number of babies born in the United States who die from SIDS annually has declined in recent decades, it is the most common cause of death among infants between one month and one year old, and some 2,300 babies die of it each year, according to Boston Children's Hospital.

Incoming information from the retina is channeled into two pathways in the brain's visual system: one that's responsible for processing color and fine spatial detail, and another that's involved in spatial localization and detecting high temporal frequencies. A new study from MIT provides an account for how these two pathways may be shaped by developmental factors.
