3D-printed bone model offers new possibilities for surgery

University of Texas at Dallas mechanical engineers have designed a 3D-printed femur that could help doctors prepare for surgeries to repair bones and develop treatments for bone tumors.

New device enables real-time monitoring of stem cell growth

Unlike most cells in the human body, stem cells have the unique ability to divide indefinitely. This unique property makes them especially appealing to scientists exploring ways to extend human lifespans or develop new methods for repairing damaged tissues.

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.

New guidance balances GLP-1 risks and benefits for surgery

Most patients may continue to safely take glucagon-like peptide-1 (GLP-1) receptor agonists as prescribed before undergoing elective surgery and gastrointestinal endoscopies, according to new clinical guidance released today by five surgical and medical societies including the American Society for Metabolic and Bariatric Surgery (ASMBS), American Society of Anesthesiologists (ASA), American Gastroenterological Association (AGA), International Society of Perioperative Care of Patients with Obesity (ISPCOP), and Society of American Gastrointestinal and Endoscopic Surgeons (SAGES).

Study challenges early intervention for asymptomatic aortic stenosis

The EVOLVED trial found that early aortic valve intervention in patients with asymptomatic severe aortic stenosis (AS) and mid-wall myocardial fibrosis on magnetic resonance imaging did not reduce the incidence of the composite primary endpoint of all-cause death or unplanned aortic stenosis hospitalization compared with guideline-directed conservative management.

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.

New funding boosts efforts to revitalize flint communities

The Prevention Research Center of Michigan has spent decades researching ways to create safer, more inviting, and accessible neighborhood spaces to improve physical and mental health. Now, $5 million in renewed funding from the U.S. Centers for Disease Control and Prevention will enable the center to continue its community-based participatory research projects through at least 2029.

Researchers identify genetic markers for cardiovascular disease

A team of researchers from Girona Biomedical Research Institute Dr. Josep Trueta (IDIBGI), Bellvitge Biomedical Research Institute (IDIBELL), IRB Barcelona, Institut Català d'Oncologia (ICO), Germans Trias i Pujol Research Institute (IGTP) has worked together to identify possible genes associated with certain metabolites - molecules involved in the body's biochemical processes - and cardiovascular risk.

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.

New test promises to end malaria

Almost half of the world's population is at risk of malaria infection, with children and pregnant women at the highest risk of getting sick and dying from the disease. Current methods to detect this potentially deadly infection rely on obtaining an invasive blood sample, and each test has significant limitations that restrict its utility.

Positive aging expectations linked to better cognitive perception

Getting older brings certain expectations, from gray hair and wrinkles to more bouts of forgetfulness. While these beliefs may seem harmless, whether a person views these changes in a positive or negative light may influence how they perceive their cognitive abilities, according to a new study from researchers in the Penn State College of Nursing.
