WASHINGTON, D.C.— Compared with a Mediterranean diet, dietary acid load decreased significantly on a low-fat vegan diet and was associated with weight loss, according to a randomized cross-over trial conducted by the Physicians Committee for Responsible Medicine and published in Frontiers in Nutrition.   “Eating acid-producing foods like meat, eggs, and dairy can increase the dietary acid load, or the amount of acids consumed, causing inflammation linked to weight gain,” says Hana Kahleova, MD, PhD, director ...

In general, evolution is a long, slow process of tiny changes passed down over generations, resulting in new adaptations and even new species over thousands or millions of years. But when living things are faced with dramatic shifts in the world around them, they sometimes rapidly adapt to better survive. Scientists recently found an example of evolution in real time, tucked away in the collection drawers of the Field Museum in Chicago. By comparing the skulls of chipmunks and voles from the Chicagoland area collected ...

The results of the CATALYST study, published in The Lancet, included data from four randomised trials with a total of 5,441 patients across the UK, Switzerland, Sweden and the United States, who had all experienced a recent stroke (between 2017-2024) due to a blocked artery and atrial ...

A new gene therapy delivery device could let hospital pharmacies make personalized nanomedicines to order. This democratized approach to precision medicine, as published in Frontiers in Science, could revolutionize how hospitals treat rare diseases, even in low-resource settings.  Rare diseases affect millions worldwide, yet the one-size-fits-all model of drug development leaves patients with few treatment options. Now a European research project called NANOSPRESSO aims to tip the balance in patients’ favor by boosting access to low-cost bespoke gene and RNA therapies.  The prototype NANOSPRESSO device combines two proven technologies—nucleic acid ...

LMU researchers have demonstrated a possible mechanism for metabolic processes without cell membranes in water-filled pores. Looking at life today, it is difficult to imagine how complex biological processes and structures could have developed from simple building blocks. All cellular processes and reactions appear to be closely interdependent and necessarily occur within a cell membrane. There is no known organism that deviates from this pattern. But how did it come about? How does a cell membrane form without metabolism? Or conversely, how does metabolism arise without a cell ...

An interdisciplinary team of experts in green chemistry, engineering and physics at Flinders University in Australia has developed a safer and more sustainable approach to extract and recover gold from ore and electronic waste. Explained in the leading journal Nature Sustainability, the gold-extraction technique promises to reduce levels of toxic waste from mining and shows that high purity gold can be recovered from recycling valuable components in printed circuit boards in discarded computers. The project team, led by Matthew Flinders Professor Justin Chalker, applied this integrated method for high-yield gold extraction ...

Optical biosensors use light waves as a probe to detect molecules, and are essential for precise medical diagnostics, personalized medicine, and environmental monitoring. Their performance is dramatically enhanced if they can focus light waves down to the nanometer scale – small enough to detect proteins or amino acids, for example – using nanophotonic structures that ‘squeeze’ light at the surface of a tiny chip. But the generation and detection of light for these nanophotonic biosensors requires ...

Hot tubs and saunas can both soothe aching muscles and provide welcome warmth, but hot tubs might offer greater health benefits. That’s the takeaway from a new study done by researchers in the Bowerman Sports Science Center at the University of Oregon, which compared the physiological effects of soaking in a hot tub to sitting in a traditional dry heat sauna or a more modern far-infrared sauna. By raising core body temperatures, soaking in hot water can help lower blood pressure, stimulate the immune system and, over time, improve the body’s ...

Combining neck surgery with intensive speech therapy is associated with greater improvements in a person's ability to communicate after a stroke than intensive speech therapy alone, finds a clinical trial published by The BMJ today. The results show improvements immediately after surgery without any long-term severe adverse events or lasting discomfort, as well as reported improvements in quality of life and post-stoke depression over six months. Stroke is the most common cause of aphasia (problems with communication, including speaking, understanding others, reading and writing). More than 60% of patients are ...

Introducing performance related pay for UK general practices initially improved quality of care, but did not seem to provide lasting improvements beyond that expected by previous trends, finds a study published by The BMJ today. And initial gains in quality seemed to reverse when financial incentives were withdrawn, say the researchers. The UK Quality and Outcomes Framework (QOF) pay-for-performance programme was introduced across the NHS in 2004 to reward general practices for providing high quality care across a range of disease indicators ...

Focusing solely on achieving weight loss for people with a high body mass index (BMI) may do more harm than good, argue experts in The BMJ today. Dr Juan Franco and colleagues say, on average, people with high weight will not be able to sustain a clinically relevant weight loss with lifestyle interventions, while the potential harms of weight loss interventions, including the reinforcement of weight stigma, are still unclear. They stress that a healthy lifestyle has important benefits, but that weight alone might not give an adequate picture of someone’s health, and say doctors should provide high quality, evidence based care reflecting individual preferences ...

Serious quality defects were found in a significant number of cancer medications from sub-Saharan Africa, according to new research from the University of Notre Dame. For the study published in The Lancet Global Health, researchers collected different cancer medications from Cameroon, Ethiopia, Kenya and Malawi and evaluated whether each drug met regulatory standards. Researchers considered a variety of factors, including appearance, packaging, labeling and, most importantly, the assay value. The assay value is the quantity of active pharmaceutical ingredient (API) found in each drug. To meet safety standards, most products should be within a ...
