Three origins of dental anxiety onset identified in study

How a brain's anatomical structure relates to its function is one of the most important questions in neuroscience. It explores how physical components, such as neurons and their connections, give rise to complex behaviors and thoughts. A recent study of the brain of the tiny worm C. elegans provides a surprising answer: Structure alone doesn't explain how the brain works.

Heavy drinkers are more likely to buy alcohol-free and low-alcohol drinks, a new report from the University of Sheffield has revealed.

A Cornell-led study has revealed how a deadly form of pancreatic cancer enters the bloodstream, solving a long-standing mystery of how the disease spreads and identifying a promising target for therapy.

From the moment they're born, newborns—or, specifically, their immune systems—must learn to fight germs without harming their own tissues.

In fatal genetic diseases like Huntington's and spinocerebellar ataxia, proteins develop long stretches of repeating letters that are prone to sticking together like Velcro.

In a recent study, researchers at the University of California San Diego School of Medicine found that a UC San Diego Health telemedicine clinic for high-risk patients to be seen immediately after leaving the hospital resulted in fewer readmissions.

Since their discovery in 2004, the grid cells in the brain, which are important for our orientation, have been regarded as a kind of "GPS in the head." However, scientists at the German Cancer Research Center (DKFZ) and Heidelberg University Hospital have now shown that grid cells work much more flexibly than previously assumed.

A new study from Finland shows that low labor market participation for non-retirement related reasons may be an early indicator of dementia already years before the first evident symptoms occur. The study also identified other social markers that may be indicative of dementia up to 10 years before a diagnosis of Alzheimer's disease, frontotemporal dementia or vascular dementia.

A new study shows that people with higher levels of the protein albumin in their urine are at increased risk of developing dementia. The study, led by researchers at Karolinska Institutet, is published in the Journal of Internal Medicine.

A Western diet, rich in fat and poor in fiber, can weaken the gut protective mucosa and increase the risk of infection and inflammation. Now, Umeå researchers have identified a milk-derived molecule that can significantly strengthen the function of the intestinal mucosa and pave the way for new dietary strategies.

What causes us to sleep? The answer may lie not only in our brains, but in their complex interplay with the microorganisms spawned in our intestines.

It is well established that gut microbiome composition plays a pivotal role in human health—yet the precise connections are still not fully understood. Researchers at the Technical University of Munich (TUM) have moved a step closer to understanding these complex interactions: they have identified a cellular mechanism that alters the gut microbiome in a way that promotes cancer. An analysis of patient data shows that the findings also apply to humans.

In order to maintain a long-term career and consistently deliver high-quality performances, professional musicians are required to exercise control over their psychological state before and during the performance. However, managing emotions can be challenging, as they are often influenced by a range of uncontrollable factors, including fellow performers and audience, venue, and the nature of the program.

Microplastics have found their way deep inside our bones, brains, and even babies. A UK study found that 100% of all 155 hot and cold beverage samples tested contained synthetic plastic particles.

Healing from any injury involves a delicate balance between scarring and inflammation—two processes that can wreak havoc as well as make repairs.

Income-based rebates for electric bicycles are helping British Columbians drive less, save money, and generate revenue for the province, a new study has found. The rebates also make e-bikes more accessible to lower-income households.

Illinois health officials are warning residents to be on alert after the state's first case of Powassan virus was confirmed in a resident who became seriously ill.

Scientists have uncovered how a key type of immune cell adapts its behavior depending on the type of infection, paving the way for better vaccines and advancing research into immune-related diseases.
