Tool helps scientists spot source of neurological disease with statistics and data science

People are diverse, and the environments they live in may influence them differently. This broad diversity increases the need for neuroimaging studies that collect data from large communities.

In a new JNeurosci paper, Julie Royo, from the Institute of Cerveau, and colleagues explored the neuroanatomy that underlies social dominance in nonhuman primates.

A comprehensive new Royal Life Saving Australia study has found a significant reduction in drowning rates, particularly among young children, but highlights continuing challenges among migrant and regional populations and in locations including rivers and beaches.

In a 2022 survey of 3,000 U.S. adults, more than one-third of respondents reported that on most days, they feel "completely overwhelmed" by stress. At the same time, a growing body of research is documenting the negative health consequences of higher stress levels, which include increased rates of cancer, heart disease, autoimmune conditions and even dementia.

An international research team led from Uppsala University has identified new mechanisms behind how the aggressive brain tumor glioblastoma spreads in the brain. Targeting the identified connection between the tumor invasion routes and the tumor cell states could be a potential new treatment strategy.

Artificial intelligence (AI) in health care is rapidly advancing beyond traditional applications. Autonomous AI agents are gaining significant attention for their potential to fundamentally transform medicine. However, researchers at the Else Kröner Fresenius Center (EKFZ) for Digital Health at TUD Dresden University of Technology highlight a growing mismatch between the capabilities of autonomous AI agents and existing medical device regulatory frameworks in the US and Europe.

Scientists know that many proteins and pathways are involved in the development and progression of neurodegenerative conditions such as Alzheimer's disease, Parkinson's disease and frontotemporal dementia (FTD), and that these proteins can be detected in the plasma of people with the conditions.

Consumption of soft drinks, supplemented with white sugar, alters the DNA of gut bacteria and affects the host immune system. The good news? These effects are reversible.

There is certainly growing awareness of the damaging effects of overexposure to the sun, including skin cancers.

Within every human culture rests the potential for a distinctly positive emotional experience that's variously characterized, in English, as feeling moved, emotionally touched, or heartwarming. Other languages rely on similar contact metaphors to describe this feeling, which has been labeled only recently by researchers as Kama Muta, a Sanskrit word for being "moved by love."

As the days stretch long and the sun lingers late into the evening, most of us welcome summer with open arms. Yet for a surprising number of people, this season brings an unwelcome guest: insomnia.

The U.S. Food and Drug Administration (FDA) has escalated the recall of a popular Dubai chocolate spread sold nationwide to its highest alert level due to salmonella risks.

It's no secret that good sleep makes for better days and stronger relationships, but how couples get that rest, in the same bed or separately, has Americans talking. According to new survey data from the American Academy of Sleep Medicine, nearly one-third (31%) of U.S. adults have opted for what has been coined a "sleep divorce," or sleeping in another bed in the same bedroom or in another space in the home to accommodate a bed partner. Adults aged 35 to 44 are most likely to engage in sleep divorce (39%) and 65 or older the least likely (18%) to do so.

Children whose mothers had higher vitamin D levels during pregnancy scored better on tests of memory, attention and problem-solving skills at ages 7 to 12 compared with those whose mothers had lower levels. That is a key finding of a new peer-reviewed study that my colleagues and I published in the American Journal of Clinical Nutrition.

Much of the pre-series attention on the 2025 British and Irish Lions tour of Australia has been on injuries, player omissions and personal rivalries.

Regulatory T cells (Treg cells) are a specialized subgroup of immune cells that play a central role in the human immune system. These cells can suppress erroneous and therefore harmful immune reactions that can lead to autoimmune diseases, for example. Furthermore, they actively promote the regeneration of tissue after injuries and thus orchestrate the wound healing process.

In a new study published in Cancer Immunology Research, scientists at the Icahn School of Medicine at Mount Sinai have developed a novel method to generate billions of rare immune cells known as conventional type I dendritic cells (cDC1s), potentially paving the way for a new class of off-the-shelf cellular cancer vaccines.

Semen, sperm, spunk, cum, ejaculate, pre-cum, seminal fluid. These are just some of the many words we use to describe what comes out of an erect penis.
