A warm, wet spring means more mosquitoes. How to protect yourself from the diseases they spread

The human body is a complex and interconnected system, where alterations caused by one disease can promote the onset of others. This tendency for certain diseases to occur together, beyond what would be expected by chance, is called co-occurrence. Thus, although there are diseases with widely known co-occurrence in certain groups of patients, such as Crohn's disease and the development of ulcers, many of the molecular mechanisms that would explain them were, until now, unknown.

Researchers at Karolinska Institutet have identified a vulnerability in certain blood cancer cells that makes it possible to eliminate the cancer cells with a drug, without harming healthy cells. The study is published in Leukemia.

Scientists at the University of Leicester are hoping the collection of poo from tigers, elephants, giraffes and other exotic animals could contain the secret to finding new medical treatments.

Mass gatherings, such as major sports events and festivals, bring together people from different regions and countries. One associated risk of such large gatherings is the potential spread of antimicrobial resistance (AMR), a growing threat that undermines the effectiveness of treatments for infectious diseases.

Scientists from Trinity College Dublin have discovered that electrically stimulating macrophages—one of the immune systems key players—can reprogram them in such a way as to reduce inflammation and encourage faster, more effective healing in disease and injury.

A new evidence review undertaken by Swansea University academics to better understand the menopause-related experiences and needs of autistic people, has revealed significant gaps in knowledge, support, and health care provision, and identifies a need for targeted resources and interventions.

An international research team led by MDI Biological Laboratory President Hermann Haller, M.D. and postdoctoral researcher Yannic Becker, Ph.D. has discovered that a little-known molecule, heparanase 2 (Hpa2), plays a critical role in maintaining blood vessels' integrity.

An artificial intelligence tool which quickly analyzes brain scans of stroke patients has helped boost chances of full recovery since being launched across England, the public health service said on Tuesday.

Vericiguat did not reduce the risk of cardiovascular mortality and heart failure (HF) hospitalizations in ambulatory patients with HF and reduced ejection fraction (HFrEF) without recent worsening, according to late-breaking research presented August 30 in a Hot Line session at ESC Congress 2025. The research was published earlier this year in the European Journal of Heart Failure.

Animals teach children empathy, tolerance, patience and the ability to love something other than themselves. Bernard Williams, the English philosopher, once said, "no symphony orchestra ever played music like a 2-year-old girl laughing with a puppy," and being a mother, I wholeheartedly agree.

For years now, research studies across the world looking at happiness across our lifetimes have found a U-shape: happiness falls from a high point in youth, and then rises again after middle age. This has been mirrored in studies on unhappiness, which show a peak in middle age and a decline thereafter.

The American Cancer Society (ACS) has released Prostate Cancer Statistics, 2025, a report on current prostate cancer occurrence and outcomes in the United States. According to the study, prostate cancer incidence rates have reversed from a decline of 6.4% per year during 2007 through 2014 to an increase of 3.0% annually during 2014 through 2021, with the steepest increase (4.6–4.8% per year) for advanced-stage diagnoses.

Clinicians typically classify meningiomas—the most common type of brain tumor—into three grades, ranging from slow-growing to aggressive.

Knee crepitus, the sound of cracking or grinding in the knee joint, is very common across all age groups.

Autism is often thought of as a childhood condition, but this is far from true. Autism is a lifelong condition—and most autistic people are adults. Yet less than 1% of autism research has focused on older autistic people.

If you're feeling sore from a run or gym session, you might wonder whether it's better to push through or give your body a rest.

Cancer kills 1 in 5 people globally. Yet, except for a one-off increase in 2021, the flow of money for cancer research has trended downward every year since 2016.

Most people recognize Alzheimer's from its devastating symptoms such as memory loss, while new drugs target pathological aspects of disease manifestations, such as plaques of amyloid proteins. Now a sweeping new study in the journal Cell by MIT researchers shows the importance of understanding the disease as a battle over how well brain cells control the expression of their genes.
