Study reveals increased mental health issues among university students during COVID-19

PhD in Public Health candidate Elaine Russell and her mentor Kenneth Griffin, professor in the department of Global and Community Health, in George Mason University's College of Public Health, worked with Tolulope Abidogun, also a PhD in Public Health student, and former Global and Community Health professor Lisa Lindley, now of Lehigh University, to analyze data from the American College Health Association National College Health Assessment (ACHA-NCHA III) in an effort to understand how university students' mental health needs changed during the COVID-19 pandemic.

Later menopause linked to increased asthma risk in women

Many studies suggest that an earlier age at menopause is more detrimental to a woman's health, leading to an increased risk for adverse health conditions such as heart disease, diabetes, osteoporosis, and depression, among others.

Urgent need to shift focus from fossil fuels to health

As multiple health threats from climate change break dangerous new records, the 2024 Report of The Lancet Countdown on Health and Climate Change calls for the trillions of dollars spent funding fossil fuels to be redirected and used to drive a rapid and fair transition to a net zero greenhouse gas (GHG) economy, instead of harming the health of billions of people across the world.

Short bursts of exercise can lower dementia risk

Just one or two sessions of physical activity at the weekend - a pattern of exercise dubbed 'weekend warrior'---may be just as likely to lower the risk of cognitive decline, which can often precede dementia, as more frequent sessions, concludes research published online in the British Journal of Sports Medicine.

Exercise linked to lower mortality risk in dementia patients

Physical activity of any intensity after a diagnosis of dementia is associated with around a 30% lower risk of death, finds research published online in the British Journal of Sports Medicine.

Study questions causal link between cannabis and brain changes

Lifetime cannabis use is associated with several changes in brain structure and function in later life, suggests an observational study, but these associations may not be causal, finds a genetic analysis of the same data, published in the open access journal BMJ Mental Health.

Machine learning reveals secrets of aging in flies and humans

Discoveries that impact lifespan and healthspan in fruit flies are usually tested in mice before being considered potentially relevant in humans, a process that is expensive and time intensive. A pioneering approach taken at the Buck Institute leapfrogs over that standard methodology.

Researchers uncover link between smell and inflammation

Researchers from the Charlie Dunlop School of Biological Sciences, in collaboration with The Oxford Research Centre in the Humanities, reveal a powerful link between olfactory loss and inflammation in a staggering 139 medical conditions. This research – led by professor emeritus Michael Leon, and researchers Cynthia Woo and Emily Troscianko – emphasizes a little-known but potentially life-altering connection: the role our sense of smell plays in maintaining our physical and mental health.

Scientists develop color-coded X-rays to detect early disease

Medical imaging is no longer in Kansas, Toto, as a team led by Penn State researchers brings traditional black and white diagnostic images of X-rays and traditional CT scans into technicolor. The researchers developed novel contrast agents that target two proteins implicated in osteoarthritis, a degenerative joint disease commonly characterized as wear-and-tear arthritis.
