Garbage-collecting immune cells can protect insulin production in pancreas

Family affluence shields children from the risks of obesity and unhealthy eating habits, even when they're surrounded by unhealthy food options, according to a study co-led by researchers at University College London (UCL).

While many parents assume that putting a child to bed means they will quickly be asleep, a new study from researchers at Brown University found that's often not the case.

Drug use disorder (DUDs), also called drug addiction, is the chronic and relapsing use of psychoactive substances in spite of considerable harm to the patient. The UN Office on Drugs and Crime has estimated that more than 250 million people around the world used illegal drugs at least occasionally in 2021, while 39.5 million people suffered from DUD.

A study led by UCLA Health Jonsson Comprehensive Cancer Center investigators found that stereotactic body radiotherapy (SBRT), a form of high-dose radiation delivered in just five sessions, after prostate surgery is safe and as effective as traditional, longer courses of radiation in preventing prostate cancer from returning.

Nearly half of adolescents and young adults with lingering symptoms of concussion suffer from eye coordination disorders that cause double and blurred vision, headaches and difficulties concentrating.

A new study by the University of California, Davis, shows how cells work together to avoid a sudden drop in blood sugar. Understanding these feedback loops could improve the lives of people with diabetes and help them avoid dangerous hypoglycemia.

Spinal muscular atrophy affects all the body's muscles. For a long time, it was considered a disease caused solely by the loss of nerve cells in the spinal cord. Now, a research team at Leipzig University's Carl Ludwig Institute of Physiology has been able to show that the cerebellum—which is important for motor coordination but also influences social and cognitive processes—also plays a role in the development of spinal muscular atrophy. The study has been published in the journal Brain.

The retina consumes oxygen at one of the highest rates of any tissue in the body, and disruptions in its oxygen supply are linked to blinding diseases such as glaucoma, age-related macular degeneration, and diabetic retinopathy. Yet researchers have struggled to noninvasively measure oxygen levels at the fine scale of retinal capillaries, where early disease changes often occur.

Frustrated by the relentless rise in health care costs, many Americans think they know who's to blame for the high cost of prescription drugs, the shuttering of local hospitals and clinics, and the merger of their favorite doctor's medical practice with a competitor: for-profit corporations and private equity firms.

Impeding a link between the body's natural clock and the brain may help reduce neurodegeneration in mice modeling Alzheimer's disease, according to a new study led by researchers at WashU Medicine and published in Nature Aging.

The treatment of a common bowel condition, diverticulitis varies widely across the world. In particular the use of antibiotics is "alarmingly high" according to the biggest data analysis of the disease to date published in eClinicalMedicine.

You can always be judged by your scars. This is the idea that sums up one of the new advances in basic and biomedical research published in the journal Science by the Spanish National Cancer Research Center (CNIO). It is the "human REPAIRome"—a name that refers to the repair of breaks in the DNA molecule.

In the open-access journal PLOS Global Public Health, Steve Haake from Sheffield Hallam University and colleagues present a model for evaluating life satisfaction. They demonstrate their model using participants in a weekly running event as a case study, finding that increases in health, especially mental health, most strongly predict improvements in life satisfaction.

A new study is the first since 2015 to examine differences in tobacco use by product type among military veterans compared to civilians, finding that veterans disproportionately use all commercial tobacco product types, including cigars and cigarettes, which pose a range of serious health risks.

A new study from the Institute of Environmental Medicine (IMM) at Karolinska Institutet shows that women with premenstrual disorders have a significantly lower quality of life compared to women without such conditions. The more severe form, premenstrual dysphoric disorder (PMDD), has the most negative impact on well-being. The findings are published in the journal JAMA Network Open.

Branching isn't just for trees. This biological process occurs in animal development, enabling organs to perform complex functions. Branch-like structures form in the lungs, kidneys, and breasts, among other places. Importantly, only in female mammary glands does most branching occur years after birth. It happens during puberty and again during pregnancy as milk ducts branch out in preparation for breastfeeding. Disturbances here have been linked to breast cancer. However, studying branching can be difficult and time-consuming.

Older adults with HIV are prescribed opioids at a higher rate and are more likely to have indicators of opioid use disorder than those without HIV, according to Rutgers Health researchers.

Researchers from the University of Copenhagen have developed a method that allows for the analysis of thousands of proteins in heart tissue. This provides entirely new insights into the characteristics of heart diseases and could pave the way for more targeted treatments.
