Most people recover from dengue fever, which is caused by a virus transmitted by the Asian tiger mosquito, but some infected individuals experience serious bleeding, a sudden drop in blood pressure, and even death.

The European Regulation list on mandatory labeling of foods includes 14 allergenic foods. Research published in Clinical & Experimental Allergy has identified eight additional foods frequently involved in food-induced anaphylaxis.

Tim Mulligan moved to central Manhattan so he could be closer to work and avoid a daily ordeal on the rattling, screeching subway, just one part of the urban noisescape that tests New Yorkers every day.

US health authorities announced Tuesday a recall of frozen shrimp potentially contaminated with radioactivity.

19 August 2025 World Humanitarian Day (WHD), established after the 2003 Canal Hotel bombing in Iraq, honours the courage of humanitarian workers who risk their lives to save others. This year, in the region where WHD began, the Eastern Mediterranean faces some of its darkest humanitarian crises. Humanitarian needs have never been greater, yet funding has fallen to historic lows. Aid workers now face impossible choices over who receives help and who is left behind. This must change—urgently, before it is too late. Against this grim backdrop, humanitarian workers are facing unprecedented attacks. Last year was the deadliest on record for aid workers worldwide—and 2025 is already set to be even worse. So far in 2025, WHO has verified 382 attacks on health care across the Eastern Mediterranean Region, resulting in 1,040 deaths and 324 injuries. Almost 80 per cent of attacks reported in 2025 occurred in the occupied Palestinian territory, while almost 90 per cent of all deaths occurred in Sudan. Aid workers in Afghanistan, Iran, Lebanon, Somalia, and Syria and Yemen have also been targeted and killed this year. Dozens of aid workers in Yemen continue to be arbitrarily detained, including one WHO staff member. We call for their unconditional and immediate release. Just weeks ago, WHO staff and their families in Gaza were subjected to humiliating treatment and forcibly evacuated from our staff housing in Deir al-Balah. One staff member remains detained―we demand his immediate release. I want to acknowledge the extraordinary bravery of health and humanitarian workers across the Region who continue to deliver lifesaving Read more...

Alice Nekesa did not know she was infected with malaria-causing parasites until it was too late. She was in the fourth month of pregnancy last year when she started bleeding, a miscarriage later attributed to untreated malaria in her.

A recent study by the University of Jyväskylä shows that participation in sports club activities among Finnish youth aged 8 to 19 has significantly increased from the 1980s to the 2020s, particularly among the youngest age groups. The work is published in the Journal of Public Health.

Conventional wisdom among neuroscientists suggests that the brain's motor functions are organized around the body, meaning certain brain areas control the hand; others the foot. An emerging alternative theory is that parts of the brain may be organized by the types of action, like reaching or using tools, no matter which body part is used to complete the task.

Self-harm in young people is a major public health concern, rates are rising, and the adolescent years present a critical period of intervention. Another modern challenge facing adolescents is sleep deficiency, with global reductions in total sleep time and inconsistent sleep patterns, and as many as 70% of teenagers getting inadequate sleep.

A plan for tapering opioids should be developed to minimize withdrawal symptoms in children receiving opioids for five or more days, according to a clinical report from the American Academy of Pediatrics (AAP) published online Aug. 18 in Pediatrics.

Mass General Brigham researchers have identified seven molecules in the blood linked to excessive daytime sleepiness, including factors related to diet and hormones.

Vaping among teens and young people is consistently linked to subsequent smoking, marijuana and alcohol use, finds an overarching (umbrella) review of systematic reviews of the evidence, published online in the journal Tobacco Control.

The presence of gastroesophageal reflux disease (GERD) is associated with an increased incidence of pulmonary diseases, but this effect may be attenuated with GERD treatment, according to research published online July 22 in Frontiers in Cell and Developmental Biology.

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.
