Chikungunya virus, which is transmitted to people by infected Aedes mosquitoes and characterized by high fever and intense joint swelling and pain, has made a resurgence in many countries around the world in recent years.

You probably have at least one "super fit" friend. Maybe they're a marathon runner, a footy player or a keen hiker. To keep themselves healthy, they may stick to a strict exercise regimen and only eat certain foods. But in most cases, these people would likely struggle to play a sport or do an activity they're unaccustomed to.

Most breast cancer patients in Uganda and Ethiopia are diagnosed too late, and many lack access to life-saving treatment. Tove Ekdahl Hjelm defends her thesis "Early-onset breast cancer in East Africa: genetics, tumor characteristics and clinical management" on June 5, where she highlights deficiencies in access to adequate care, but also that more lives can be saved.

New results from the Phase III SUNRISE clinical trial show that tezepelumab significantly reduced the need for long-term oral corticosteroid use in adults with severe oral corticosteroid-dependent asthma while maintaining asthma control and improving key clinical outcomes. The findings were published in The Lancet Respiratory Medicine.

A study led by researchers at the Universitat Autònoma de Barcelona (UAB) and the Josep Carreras Leukemia Research Institute (IJC) along with researchers from Rutgers University (U.S.) has identified the Sirtuin 7 (SIRT7) protein as a new essential factor in maintaining the genome stability of male germ cells over time. The study, conducted with mice, is published in the journal Nature Communications.

Artificial intelligence (AI)-powered chatbots respond to everyday health-related questions from general users with nearly 76% accuracy, which raises concerns about their trustworthiness in real-world client-facing applications, according to a new study led by Penn State researchers.

A study published in The Lancet Public Health found that Rx Kids, the nation's first community-wide prenatal and infant cash prescription program, led to significant improvements in birth outcomes for infants born in Flint, Michigan. The program reduced low birthweight and preterm birth rates and prevented admissions to the neonatal intensive care unit, or NICU.

Researchers have found that consuming lower amounts of protein-rich foods may negatively affect physical functioning as people grow older, underscoring the vital function protein plays in preserving mobility and muscle strength in adulthood. In a large aging cohort study published in the journal Nutrients, the researchers report that regular dietary habits, particularly the consumption of protein-rich foods, can influence how well individuals move and perform daily activities later in life.

Alzheimer's disease is a neurodegenerative disease characterized by a progressive decline in mental functions and memory loss. Along with frontotemporal dementia and some other neurodegenerative disorders, Alzheimer's disease has been associated with an accumulation inside neurons of abnormal clumps of a protein called "tau."

Many people living with dementia never receive an accurate diagnosis, in part because Alzheimer's disease, Parkinson's disease and related conditions are notoriously difficult to tell apart and often occur together. Now, a new tool based on artificial intelligence and a simple blood draw may provide clarity.
