The 'Catch-22' of aging: Our immune system protects us by committing our cells to die

Australians are living longer than ever before. While this is broadly good news, aging well comes with a range of challenges.

A research group led by The University of Osaka has developed a novel method for analyzing cancer metabolism, revealing new insights into cancer's inefficient energy process.

Data now available on LawAtlas.org describe details of state, county, and city earned sick leave laws across the 75 largest cities in effect as of July 1, 2022, through June 1, 2024. The data are a longitudinal version of the assessment developed and published by CityHealth, an initiative of the de Beaumont Foundation and Kaiser Permanente, with the Center for Public Health Law Research at the Temple University Beasley School of Law.

Erika Perez was diagnosed with high blood pressure during her third pregnancy. Ten days after giving birth to her child, she suffered a heart attack. Years later, she had a stroke. Perez's story is a powerful reminder of the health risks that come with high blood pressure, also known as hypertension.

The majority (64%) of young adults in Britain say they have experienced mental health difficulties, with a third (32%) expecting to need support in the coming year, according to polling commissioned from YouGov by UCL's Grand Challenge of Mental Health & Wellbeing.

An artificial intelligence (AI) deep learning tool that estimates the malignancy risk of lung nodules achieved high cancer detection rates while significantly reducing false-positive results. Results of the study, which used data from large, multi-site lung cancer screening trials, were published in Radiology.

Depression is one of the most common mental health challenges, but its early signs are often overlooked. It is often linked to reduced facial expressivity. However, whether mild depression or subthreshold depression (StD) (a mild state of depressive symptoms that does not meet the criteria for diagnosis but is a risk factor for developing depression) is associated with changes in facial expressions remains unknown.

An estimated 7.2 million Americans over age 65 currently live with Alzheimer's disease (AD). That number is expected to nearly double to 13.8 million by 2060. These increases reflect more than demographic shifts; they point to a growing public health crisis that requires a new, proactive approach. While chronological age is the strongest known risk factor for cognitive decline, losing cognitive function is not an inevitable part of aging.

After years of progress in reducing malaria cases, Rwanda is confronting a surprising resurgence and signs of treatment resistance that have forced officials to revisit vaccine intervention the country once declined.

The CORE-MD (Coordinating Research and Evidence for high-risk Medical Devices) consortium has published new consensus recommendations today in The Lancet Regional Health Europe, that set out scientifically robust methodologies for clinical investigations of high-risk medical devices.

James Madison University and Case Western Reserve University researchers describe a phenomenon they term the Rumpelstiltskin effect, in which the act of receiving a clinical diagnosis itself produces therapeutic benefit independent of medical intervention.

A new study led by Prof. Lynn Chenoweth from UNSW's Center for Healthy Brain Aging (CHeBA) has shown that educating hospital staff in person-centered dementia care leads to better care experiences, greater staff confidence, and improved rehabilitation outcomes for older Australians.

Tuberculosis, or TB, an airborne bacterial respiratory infection, is one of humanity's oldest foes and is today the world's leading cause of death from infectious disease, claiming more than 1.2 million lives each year. The single available vaccine protects young children from severe cases of TB but does little to prevent the spread of disease in adolescents and adults.

Northeastern University professor Raymond Booth first learned about propranolol, a drug developed to treat high blood pressure, in pharmacy school around 1978.

California's late summer COVID surge is showing signs of peaking, but the state's war with the Trump administration over vaccines is just beginning.

"Liquid biopsy" tests using blood samples to screen for multiple types of cancer are attracting much attention, for their potential to catch unseen tumors.

Chronic kidney disease is a growing health concern affecting about 1 in 10 Swedes. The condition involves a gradual decline in kidney function, which can lead to the need for dialysis or transplantation.

Critics of affirmative action have launched a long-shot appeal aimed at stopping California from requiring training on unconscious bias in every continuing medical education class.
