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 ...

Scientists at the University of Oxford have unveiled a pioneering method for capturing the full structure of ultra-intense laser pulses in a single measurement.

This would have transformative applications in many areas, including research into new forms of physics and realising the extreme ...

Biological drugs have improved the lives of many people with severe asthma. However, a new study from Karolinska Institutet in Sweden shows that some immune cells with high inflammatory potential are not completely eradicated after treatment. Biological drugs (biologics) have become an important tool in the treatment of severe asthma. “They help most patients to keep their symptoms under control, but exactly how these drugs affect the immune system has so far remained unknown,” says Valentyna Yasinska, consultant ...

A new international study drawing on 73 million nights of data reveals that our sleep patterns are seriously shaped by the day of the week, the season, and where we live. Working with sleep data from more than 116,000 adults across the globe, Flinders University sleep experts used insights from an FDA-cleared under-mattress device to track sleep duration and timing over 3.5 years. Lead author, Dr Hannah Scott from FHMRI Sleep Health says the findings give a detailed look at how geography, seasons, and our day-to-day schedules quietly disrupt the way we sleep. “Sleep patterns aren’t just about habits – they’re deeply connected to the environment around ...

Niigata, Japan— In a remarkable advancement for soil science, researchers from Japan have developed a novel method for estimating microbial biomass using water-extractable organic matter (WEOM) from air-dried soils. This innovative approach not only simplifies the estimation process but also eliminates the need for toxic solvents typically used in traditional methods, such as chloroform fumigation extraction. A research was conducted by a dedicated team from Niigata University, Kyushu University, Japan Atomic Energy Agency, and Anhui Academy of Agricultural Sciences researchers. The study analyzed 50 soil samples from ten diverse profiles across various regions in Japan, including six ...

New commentary published in the Journal of the Royal Society of Medicine warns that current risk-based regulatory approaches to Artificial Intelligence (AI) in healthcare fall short in protecting patients, potentially leading to over- and undertreatment as well as discrimination against patient groups. The authors found that while AI and machine learning systems can enhance clinical accuracy, concerns remain over their inherent inaccuracy, opacity, and potential for bias which are not adequately addressed by the current regulatory ...

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 ...

More effective platforms for drug and medical device development and better cross sector engagement are urgently required to prevent the ‘unacceptably high’ newborn death rate, according to a global report.

SYDNEY, Australia - A new study involving 121 former elite rowers from Australia has revealed one in five develops atrial fibrillation (AFib). This common heart rhythm condition can lead to stroke and heart failure in some individuals, but the researchers identified new genetic and clinical tools that enable early preventive strategies.   Researchers also found the retired rowers, who include former Olympians, are almost seven times more likely to develop AFib than the general population – despite having far fewer AFib risk factors like high ...

A common medication already used for autoimmune diseases such as rheumatoid arthritis is effective for patients with giant cell arteritis, according to findings from a team at the Perelman School of Medicine at the University of Pennsylvania published in the New England Journal of Medicine. Causing the body’s immune system to attack blood vessels in the head, neck, and other areas, giant cell arteritis often leads to headaches, vision loss, and even aortic aneurysms. But nearly half of patients taking upadacitinib in a new Phase 3 clinical trial achieved sustained remission— while reducing their dependence on glucocorticoids (typically called “steroids”), ...
