Researchers from Carnegie Mellon University's School of Computer Science, the University of Pittsburgh School of Medicine and the University of Washington shed new light on Alzheimer's disease that could point to new directions for treatment.

Researchers have discovered that the human brain undergoes widespread age-related changes in genome regulation beginning in midlife that may help explain why aging is the greatest risk factor for neurodegenerative diseases such as Alzheimer's.

A major pillar of cancer immunotherapy involves stimulating T cells, the specialized killers of the immune system, to attack tumors.

Disrupted sleep and anxiety may be an ongoing issue for many people after the pandemic, whether due to COVID-19 directly or to the stress and anxiety caused by the global pandemic, and may contribute to the fatigue commonly reported by people with Post-COVID-19 Syndrome (PCS, or 'long COVID').

Cardiovascular risk factors are linked to higher risk of heart disease, but it has been unknown how they are related to abrupt closure of the coronary arteries leading to heart attack and sudden cardiac death.

Nearly half of childhood tumors treated with common types of chemotherapy showed detectable DNA changes linked to treatment within 18 months, according to a new international study led by The Hospital for Sick Children (SickKids).

New research has shown that RNA-based testing can improve the detection and interpretation of clinically actionable genomic alterations leading to MET exon 14 skipping in lung cancer patients—important biomarkers that may be missed by DNA-only approaches.

For decades, selenium has been recognized as an essential micronutrient, and glutathione peroxidase 4 (GPX4)-a selenium-containing enzyme-has been widely regarded as the central guardian against ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation.

A dream holiday, an exotic destination, a long-haul flight, and finally some well-deserved rest. The problem is that many travelers arrive at their destination only to spend the first days of their vacation struggling with fatigue, sleep disturbances, low energy levels, and digestive issues.

Scientists at The Wistar Institute have identified a new mechanism behind the chemotherapy resistance that makes ovarian cancer so lethal.

Lifestyle modification is the cornerstone of managing metabolic dysfunction-associated steatotic liver disease (MASLD), a growing cause of chronic liver disease worldwide.

Epilepsy affects over 50 million people worldwide, making it one of the most common neurological disorders.

A patient with a severe infection is prescribed a potent antibiotic. Hopes for improvement are high, but just after treatment is given, resistance to the drug increases thousands of times. How could this happen?

For patients diagnosed with cancer, continuing to smoke during treatment may shorten survival.

Antimicrobial resistance is one of the world's most alarming public health challenges, because the multidrug-resistant (MDR) gram-negative bacteria increasingly render even last-line antibiotics ineffective, leading to substantially higher mortality rates.

A new mouse study led by UCLA Health suggests that inflammation during pregnancy can trigger autism-like changes in offspring, but also that those brain and behavior effects may be rapidly but temporarily reversible in adulthood with a short-term dose of the immunosuppressive drug rapamycin.

Primary biliary cholangitis is a rare autoimmune disease that affects the liver and can progress to cirrhosis. It occurs when the immune system attacks the small bile ducts within the liver. As a result, bile builds up, leading to inflammation and progressive liver damage. Although a first-line treatment exists, 40% of patients do not respond adequately to it or cannot tolerate it, so new treatment options need to be developed.

Vitiligo is an autoimmune disease in which the body's immune system attacks and destroys melanocytes, the cells that produce the skin pigment melanin. Once the melanocytes are gone, the skin turns white, leading to the characteristic skin patches of the disease.

An international study involving LMU found regional differences in childhood lymphoid leukemia mortality across Brazil.

In a 14-day study of 101 healthy UK adults, greater social jetlag was associated with a later distribution of energy intake, particularly greater late-evening intake among women. The effects were modest, varied by sex and day type, and did not establish whether total daily energy intake differed between groups.
