Antibody therapy shows promise in reducing Zika virus in reproductive tissues

A diet rich in omega-3 fatty acids, found predominantly in fish oils, may help ward off the development of shortsightedness (myopia) in children, while a high intake of saturated fats, found in foods such as butter, palm oil, and red meat, may boost the risk of the condition, finds research published online in the British Journal of Ophthalmology.

Amylin, a hormone that controls appetite and blood sugar by activating three different receptors in the brain, could be the basis for the next blockbuster obesity drugs. A University of Oklahoma study published in the journal Science Signaling reveals a new understanding of how amylin receptors react upon being activated, an advancement that will be crucial to the field of drug development.

By analyzing millions of messenger RNA molecules (mRNA) during the course of ALS, researchers at Stockholm University, in collaboration with scientists at the Paris Brain Institute and Örebro University, have identified why certain nerve cells are resistant to the disease and what happens in the sensitive nerve cells when they are affected. The study, published in the journal Genome Research, focuses on a hereditary form of ALS caused by mutations in the SOD1 gene.

A Yale research team has created a new computer tool that can pinpoint when exactly genes turn on and off over time during brain development—a finding that may one day help doctors identify the optimal window to deploy gene therapy treatments.

Older adults who regularly participated in a community-based exercise program were able to slow—and in many cases reverse—declines in cardio fitness and strength that naturally come with age, a new McMaster study shows.

School connectedness buffers against depression symptoms associated with being a victim of peer bullying in adolescence, according to a study published in BMC Public Health. School connectedness was measured by the degrees of inclusiveness, closeness, happiness and safety of adolescents within the school environment.

A group of nerve cells known for their role in detecting chemical irritation, tissue damage, heat, and pressure now emerge as critical defenders against the worst ravages of the flu caused by an overactive immune response, according to new research by scientists at Harvard Medical School and the Harvard T.H. Chan School of Public Health.

Researchers at the University of Missouri are on a mission to help patients recover from hip surgery with less pain, and they may have found an innovative solution: using the patient's own cartilage cells.

The percentage of physicians who go on to practice in New York State after completing their residency training continues to climb.

Cardiovascular disease is the leading cause of premature deaths in patients with bipolar disorder worldwide. In a novel study in young adults (aged 20–45) with bipolar disorder, researchers were able to detect subtle (subclinical) abnormalities in how their heart muscle functions and pumps blood before the onset of heart failure by measuring peak systolic strain and myocardial work.

Stroke remains one of the leading causes of long-term disability worldwide, affecting millions each year. Among its most debilitating consequences is gait impairment, which affects over 80% of stroke survivors. Impaired walking not only reduces independence but also limits participation in daily and social activities, significantly diminishing the quality of life.

Inducing acute stress reliably under controlled conditions remains a major challenge in scientific research. Finding paradigms that elicit stress reliably and remain ecologically valid is difficult.

Autism spectrum disorder (ASD) affects an estimated 1 in 31 children in the United States by 2025, and prevalence in East Asian countries, such as South Korea, Singapore, and Japan, may be even higher than those in the United States. Despite its increasing prevalence, the underlying causes of ASD remain poorly understood, and there are currently no curative, preventive, or treatment options available.

A new cross-national study reveals that older adults with disabilities are significantly less likely to receive preventive care, such as flu vaccinations, eye exams, and dental checkups. This gap remains the same for eye exams and dental care but is eliminated for flu vaccinations in countries that invest more in public health care.

Despite the increasing recognition of long COVID as a condition, many patients still face dismissal by medical professionals, misattribution of their symptoms to psychological causes, or simply being left to fend for themselves. The study describes the response many encounter from professionals as "medical gaslighting," disbelief and dismissiveness.

As overdoses from fentanyl and opioids continue to rise, many communities have created interactive overdose dashboards that show demographic, geographic and time trends in suspected overdoses and community resources to help with substance abuse.

A new study reveals that individuals who enjoyed whole milk during the 1970s and early 1980s had a higher risk of mortality. However, beginning in the mid-1980s, a significant change occurred.

I recently asked myself if I'll still have a healthy brain as I get older. I hold a professorship at a neurology department. Nevertheless, it is difficult for me to judge if a particular brain, including my own, suffers from early neurodegeneration.
