Playing video games for more than 10 hours a week could have a significant impact on young people’s diet, sleep and body weight, according to a new Curtin University-led study published in Nutrition.   Researchers surveyed 317 students from five Australian universities with a median age of 20 years old.   They split participants into three groups depending on the self-reported amount of time spent playing video games, from ‘low gamers’ (0-5 hours per week) to ‘moderate gamers’ (5-10 hours) and ‘high gamers’ ...

Background Various tissues and organs in the human body, such as nerves, heart, bones, and skin, rely on bioelectrical signals to maintain function and support regeneration. Although conventional electrical therapies are effective, they require external power sources and invasive electrodes, leading to high risks of infection and reduced patient comfort. This review innovatively proposes the use of electrospinning to fabricate electroactive fibrous scaffolds, which mimic the structure of the extracellular matrix while providing electrical activity, thereby enabling non-invasive and self-powered tissue repair. Research Progress Electrically sensitive ...

Fingertip monitors known as pulse oximeters that can be used at home to detect low blood oxygen levels (hypoxaemia) give higher readings for patients with darker than lighter skin tones, finds the largest study on this topic published by The BMJ today. This means that low blood oxygen levels may be missed in patients with darker skin tones, potentially delaying care, while patients with lighter skin tones may get unnecessary treatment. Pulse oximeters use light to measure the amount of oxygen in the blood (SpO2). For most people, a normal pulse oximeter reading is between 95% and 100%, with readings below 90-92% generally considered low and requiring medical ...

Wearing a cast for six weeks appears to be no less effective than surgery for healing unstable ankle fractures and carries fewer treatment related harms, finds a clinical trial from Finland published by The BMJ today.   Around two thirds of all ankle fractures involve a break in the fibula (the outer ankle bone). Known as Weber B fractures, they leave the ankle either stable or unstable (at risk of falling out of alignment).   Surgery remains the main treatment for Weber B ankle fractures deemed unstable, despite recent trials and guidelines increasingly supporting non-surgical options in selected patients.   To explore this further, researchers set out ...

Alcohol-free and low alcohol (“nolo”) drinks have the potential to improve public health, but experts in The BMJ today call for a precautionary approach that maximises potential benefits (eg. increased substitution of alcoholic drinks with nolo alternatives) while minimising risks (eg. preventing encroachment of nolo drinks into alcohol-free spaces). Sales of alcohol-free and low alcohol drinks have increased substantially over recent years, driven by improved manufacturing techniques and consumer demand for better and healthier alternatives to alcoholic drinks, ...

Key findings Adding 100 mL of water at room temperature (25 ℃) to 1 g of the alloy powder results in nearly complete hydrolysis and yields a high hydrogen output in a short time. After correcting for water vapor, the measured hydrogen volume corresponds to approximately 737–760 mL H₂ per gram of powder (produced within about 10 minutes). Raising the water temperature to 60 ℃ further increases both reaction rate and total yield, reaching up to ≈835 mL H₂/g (uncorrected value). Microstructural analysis using SEM/TEM/EDS shows that the gas-atomized powders are spherical (diameter ~6–65 ...

Archival discoveries including a 19th-century autobiography transform our understanding of Shadrack Byfield, an English veteran of the War of 1812 who buried his own amputated arm and designed a custom prosthesis. A recurrent character in TV documentaries, books and museum exhibits in the USA and Canada, Byfield has been celebrated as an uncomplaining British soldier. But the new evidence reveals Byfield’s tenacious pursuit of veterans’ benefits and his struggles with pain, poverty, and the police.   ‘They came and pushed me about, ...

The University of Birmingham today (15 Jan) launched a new West Midlands-based facility for separating and recycling rare earth magnets that will help to reduce the UK’s reliance on imports of rare earth metals, alloys, and magnets.   Rare earth magnets are amongst the key ‘critical minerals’ that are integral to modern life.

One of the hallmarks of Alzheimer’s disease is the clumping of proteins called Tau, which form tangled fibrils in the brain. The more severe the clumping, the more advanced the disease is. The Tau protein, which has also been linked to many other neurodegenerative diseases, is unstructured in its normal state, but in the pathological state it consists of a well-ordered rigid core surrounded by floppy segments. These disordered segments form a “fuzzy coat” that helps determine how Tau interacts with other molecules. MIT chemists have ...

Just like every other creature, bacteria have evolved creative ways of getting around. Sometimes this is easy, like swimming in open water, but navigating more confined spaces poses different challenges. Nevertheless, new research from the University of Chicago shows that a diverse group of bacteria has learned how to use the same basic movements to move through a wide range of environments no matter how complex, from unconstrained fluids to densely packed soil and tissues. ‘Run-and-tumble' vs ‘hop-and-trap' Some of the most common bacteria, like Salmonella and ...

  Audio: Study summation by Sue Anne Bell   Older adults who were exposed to heavy rainfall after Hurricane Harvey in 2017 faced a 3% increase in the risk of death within the following year, a new University of Michigan study found.   "These findings add to the evidence that disasters don't just cause short-term disruptions. They expose and magnify the underlying fragilities in our health systems," said lead author Sue Anne Bell, U-M associate professor of nursing. "For older adults who rely on regular ...

At the time of marketing authorization, many questions regarding the optimal use of new cancer drugs remain unanswered. This concerns, for example, the appropriate dosage for different patient groups and treatment duration, but also the comparison of the available treatment options with each other, or the optimal sequence. Because of these gaps in knowledge, the best possible results for patients are often not achieved. This problem has become more acute in recent years because efforts have focused more on accelerating the marketing authorization of new drugs than on optimizing their use in everyday clinical practice. The ...

Highlights: A new study has found that for people with moderate hearing loss, being prescribed hearing aids had no impact on cognitive test scores. Following people with moderate hearing loss, researchers compared those prescribed hearing aids to those without prescriptions. They found both groups had similar average test scores on memory and thinking tests. However, researchers also found having hearing aid prescriptions was associated with a 33% lower risk of dementia. This finding does not prove that hearing aids reduce the risk. It only shows an association. While no improvement in cognitive test scores was unexpected, factors like most participants having good cognitive health ...

Teeth provide a wealth of information about the lives of Iron Age Italians, according to a study published January 14, 2026 in the open-access journal PLOS One by Roberto Germano of Sapienza University of Rome, Italy and colleagues. Comparing the lifestyles of ancient cultures requires detailed information about the lives of long-deceased individuals. Human teeth are an excellent resource for this data, being very resilient structures that act as archives of life history information. In this study, Germano and colleagues combined multiple dental analyses to interpret details about health and diet in the Iron Age Italian site of Pontecagnano, dating to the 7th ...

A new study suggests that, with low to moderate levels of global greenhouse emissions in coming decades, more of India could become suitable for growing avocados. However, with high enough emissions, growing zones could shrink and destabilize by 2070. G. Karunakaran of the Indian Council of Agricultural Research’s Indian Institute of Horticultural Research and colleagues present these findings in the open-access journal PLOS One on January 14, 2026. Rising global demand for avocados makes them an economically significant fruit ...

Pregnant individuals with inflammatory bowel disease (IBD) have higher levels of pro-inflammatory immune molecules, known as cytokines, in their vaginal mucosa than their healthy counterparts, according to a new study published January 14, 2026 in the open-access journal PLOS One by Ana Maldonado-Contreras of University of Massachusetts Chan Medical School, U.S., and colleagues. However, the study also suggested that higher-quality diets, with more vegetables and fewer added sugars, are associated with lower levels of pro-inflammatory cytokines in pregnant women both with and without IBD. Pregnant individuals with IBD ...
