Genetic testing of IVF embryos can help women over 35 conceive faster

Government representatives call for standardized public health procedures at the close of a 3-day simulation exercise. 25 August 2025, Cairo, Egypt – Government representatives from Egypt, Libya, Sudan and Tunisia — major countries on migratory routes in North Africa — convened in Cairo from 18–20 August for a 3-day table-top simulation exercise (SimEx) organized by the World Health Organization (WHO) and the International Organization for Migration (IOM). The 4 countries share porous borders. Displaced people often face overcrowding, inadequate shelter, poor sanitation and limited access to timely, quality health care services. These conditions create public health risks for migrants, refugees and host communities. When health care services are not accessible to all, it fuels inequity and undermines health security. The SimEx brought together delegates from Ministries of Health, Interior and Transport to test preparedness for cross-border population movements in line with the International Health Regulations (IHR 2005). Focused on ensuring access to health services for refugees, migrants and other people on the move while reinforcing national health security, it involved interactive and practical exercises on stakeholder coordination for public health event prevention, detection and response, aiming to improve compliance with IHR 2005, enhance communication between sectors and identify gaps to strengthen cross-border public health management, including access to health care services. At the conclusion of the exercise, the multisectoral government representatives recommended standardizing public health procedures across borders to Read more...

While the process via which different types of neurons are produced, also known as neurogenesis, has been the focus of numerous neuroscience studies, its genetic and biological underpinnings in humans have not yet been fully elucidated. This is also true for immature neurons arising from adult hippocampal neurogenesis, known as immature dentate granule cells (imGCs), which support the brain's adaptation in response to experiences throughout adulthood.

With a longtime vaccine critic leading the nation's health departments, you might be wondering whether there's a new flu shot this fall.

The U.S. Food and Drug Administration has cleared the Signos Glucose Monitoring System, an over-the-counter glucose monitoring system for weight management.

Pediatricians should screen children annually for mental or developmental issues, the American Academy of Pediatrics (AAP) recommends in a new clinical report.

A new study led by investigators from Mass General Brigham, Harvard T.H. Chan School of Public Health, and the Broad Institute of MIT and Harvard suggests that a Mediterranean-style diet may help reduce dementia risk. The study, published in Nature Medicine, found that people at the highest genetic risk for Alzheimer's disease benefited more from following a Mediterranean-style diet, showing a greater reduction in dementia risk compared to those at lower genetic risk.

A research team at Kyoto University has discovered STAG3-cohesin, a new mitotic cohesin complex that helps establish the unique DNA architecture of spermatogonial stem cells (SSCs), the stem cells that give rise to sperm. This "DNA organizer" is crucial for sperm production in mice: without STAG3, SSCs cannot differentiate properly, leading to a fertility problem.

US health authorities have suspended the license for the Ixchiq vaccine against the chikungunya virus following reports of "serious adverse events," the drug's French maker said Monday.

New research indicates that many patients with advanced cancer report receiving treatment focusing on longevity over comfort, even when their goal is the opposite. The findings are published in Cancer.

A recent review of the Canadian Task Force on Preventive Health Care underscores the need for expert bodies to produce evidence-based guidance and that Canada should ensure a renewed task force is adequately funded and supported, argues a commentary in the Canadian Medical Association Journal.

Tobacco smoking is the number one cause of preventable disease and death in Canada; it is highly addictive and hard to stop. Recognizing these challenges, a new guideline from the Canadian Task Force on Preventive Health Care provides a menu of effective options to help people quit smoking, with behavioral and medication options and a natural health product that can be tailored and combined for personal choice.

Children residing in "very low-opportunity" neighborhoods are up to 20 times more likely to be hospitalized for gun injuries than those living in the most advantaged areas, reports a new multi-state study published in Pediatrics titled "Pediatric Firearm-Related Hospital Encounters by Child Opportunity Index Level."

Having a hard time bending over to put your shoes on? Experiencing pain in the knees, groin, thigh or back? A survey by The Ohio State University Wexner Medical Center reveals many people don't realize these symptoms can mean there's a problem in the hip.

The first study of its kind to compare cardiovascular risk in type 1 diabetes (T1D) and type 2 diabetes (T2D) in both men and women shows that younger men with T2D have worse mortality and cardiovascular disease (CVD) outcomes than those with T1D, whereas for women of all ages, almost all outcomes are worse for T1D than for T2D.

Inflammatory bowel disease, or IBD, is an umbrella term for a group of chronic conditions that cause inflammation and swelling in the digestive tract. It primarily includes two conditions: ulcerative colitis and Crohn's disease. While both involve inflammation, they affect different parts of the gastrointestinal (GI) tract and behave differently over time.

Over the course of their lives, humans can sometimes acquire fear responses to specific stimuli, animals, objects or situations, typically following adverse experiences or traumatic events. Understanding the brain processes associated with the extinction of these learned fearful responses could guide the development of more effective therapeutic strategies to treat phobias or other anxiety disorders.

When Luigi Mangione was arrested for the alleged murder of the CEO of UnitedHealthcare in December 2024, public reaction shocked observers. Far from universal condemnation, many people expressed support. This was especially true among younger people, with polls showing 41% of young adults viewed the murder as acceptable.

The health advice that keeps you from getting sick might actually harm you once you're already ill. This counterintuitive medical reality has a new name: "Cuomo's paradox", coined by Professor Raphael Cuomo at UC San Diego School of Medicine after analyzing findings across numerous studies.
