Tough caring responsibilities reduce brain function in people over 50, but light caring responsibilities may actually benefit mental performance in middle age, new research from UCL has found. Regarding this research, age and aging, The researchers used data from the UK Longitudinal Study of Aging (ELSA) from 2004-05 to 2021-23. ELSA is a long-term, nationally representative survey led by UCL that collects a wide range of information from around 20,000 people aged 50 and over in the UK who are re-interviewed every two years. The survey consists of 12 topics and includes information about participants’ caregiving responsibilities and physical and…

Mothers who work in jobs where they are frequently exposed to toxic chemicals or experience high levels of stress are more likely to have children with autism spectrum disorder (ASD), suggests an original study published online in the journal Children’s Health. Occupational and environmental medicine. ASD is a lifelong neurodevelopmental condition characterized by impairments in social communication and restricted or repetitive behaviors. Previous research has shown a potential association between some maternal occupations and children’s ASD, but the results have been inconsistent. However, these previous studies tended to use small study samples or rely on self-reported exposure data. They also…

New multi-site study presented at natural mental health It has been found that using cannabis and tobacco together increases the risk of developing psychiatric disorders such as schizophrenia, which are considered high-risk. Researchers led by Heather Ward, M.D., assistant professor of psychiatry and behavioral sciences and director of neuromodulation research at Vanderbilt Health, analyzed data from more than 1,000 participants in the North American Progenitor Longitudinal Study, which tracks individuals at “clinical high risk” for psychosis. These people often experience mild or early symptoms but have not yet developed a full-blown psychotic disorder. The prevalence of cannabis and tobacco…

UBC Okanagan researchers have uncovered the process plants use to produce mitraphylline. Mitraphylline is a rare natural compound that has received attention for its possible cancer-fighting properties. Mitraphylline belongs to a unique class of phytochemicals known as spirooxindole alkaloids. These molecules are known for their unusual twisted ring structures and potent biological effects, including anti-inflammatory and antitumor activities. Scientists have been studying these compounds for years, but the exact molecular steps plants use to produce them have remained unclear. Groundbreaking discoveries in phytochemistry The mystery began to unravel in 2023, when Dr. Tutui Dunn’s team at UBC Okanagan’s Irving K.…

A team led by USC stem cell scientist Dr. Zhongwei Li has created some of the most complex and mature laboratory-cultured kidney models to date. With the support of a three-year grant from the California Institute for Regenerative Medicine (CIRM), Lee and colleagues are now mapping the properties, structure, and function of these mini-kidney structures, known as human synthetic kidney organoids (hSKOs), to show how they can advance disease research. hSKO, small organ-like structures grown from human stem cells, could ultimately contribute to efforts to build replacement organs for transplant patients, while also providing a more immediate and powerful way…

Researchers at Rice University and the University of Texas MD Anderson Cancer Center have developed a miniature imaging device powered by artificial intelligence that could change the way clinicians detect cancer. The technology aims to bring high-resolution, real-time diagnostics directly to the point of care and was recently described in a paper published in the Proceedings of the National Academy of Sciences. The device, called PrecisionView, is a handheld endoscope that overcomes the limitations of medical image processing by combining advanced optical technology and deep learning. This system allows clinicians to visualize both intracellular structures and underlying blood vessels over…

Scientists at the Icahn School of Medicine at Mount Sinai have successfully reversed aging in hematopoietic stem cells in mice by repairing defects in structures known as lysosomes. The survey results are cell stem cellspoint out that lysosome dysfunction and overactivity are the main causes of stem cell aging, and show that restoring proper lysosome activity can rejuvenate old stem cells and improve their ability to regenerate blood and immune cells. Lysosomes act as internal recycling centers of cells. They break down proteins, nucleic acids, carbohydrates, and lipids, helping cells process waste products and recycle materials needed for important biological…

When a couple has their first child, women generally experience a reduction in long-term income compared to their male partners. New analysis shows that this overall relative income loss is significantly smaller for women with more formal education than their partners. The study was recently published in the journal Social Science Research. Parenting acts as an abrupt fork in the career trajectories of men and women. After the birth of a first child, mothers routinely experience a significant and sustained decline in their labor market income. Fathers generally believe that their income will remain untouched. Economists and sociologists refer to…

A genetic predisposition to strong grip strength is associated with better cognitive health in older adults. Researchers recently discovered that people born with DNA traits that favor muscle strength tend to decline mentally more slowly as they age. According to a recent study published in Neurobiology of Aging, this relationship operates independently of how much people exercise. Loss of motor function, including basic physical movements and muscle control, often precedes decline in cognitive function. Medical professionals frequently measure hand grip strength using simple hand-held devices as an easy indicator of a person’s overall vitality. Decreased grip strength is known to…

BioMarin Pharmaceuticals is consolidating employees tied to the acquired company’s headquarters in Princeton, New Jersey, shortly after finalizing a $4.8 billion deal with fellow rare disease company Amicus Therapeutics. Starting in August, 58 positions will be eliminated at Amicus headquarters in Princeton, according to the Worker Adjustment and Retraining Notification Act (WARN) filed this week in New Jersey. According to the layoff notice, the layoffs are scheduled to end around the end of October (PDF). A BioMarin spokesperson confirmed in an emailed statement to Fiers that the job cuts are related to the acquisition. “With the completion of the acquisition,…
