College commuters: Link between students’ mental health, vehicle crashes
2025-02-05
Young adults are a higher risk group for being in a crash while driving due likely to inexperience with driving, driving under the influence, and a greater propensity to take risks while driving. Although research has explored sociodemographic links of driver crashes based on age, sex and socioeconomic status, reports on the relationship between crashes and mental health are sparse.
A new Florida Atlantic University study fills a notable gap by exploring the correlation between commuter college students’ mental health status and being in a crash while driving. Commuter students, often lower-income, older, or balancing family responsibilities, face greater ...
Using sugars from peas speeds up sour beer brewing
2025-02-05
Sour beers have become a fixture on microbrewery menus and store shelves. They’re enjoyed for their tart, complex flavors, but some can require long and complicated brewing processes. Researchers reporting in ACS’ Journal of Agricultural and Food Chemistry brewed new sours in less time using a seemingly strange ingredient: field peas. The experimental beers had fruity — not “beany” — flavors and other attributes comparable to a commercial Belgian-style sour, but with shorter, simpler brewing steps.
“Sour beer is the beer enthusiast’s alternative to Champagne. By using sugars derived from peas that yeast ...

Value-added pancakes: WSU using science to improve nutrition of breakfast staple
2025-02-05
PULLMAN, Wash. — Typical breakfast pancakes are soft, fluffy and delicious but, sadly, not terribly healthy.
Food scientists at Washington State University are working to change that by boosting the popular morning favorite’s nutritional value while enhancing its taste and texture.
“Generally, pancakes are made with refined flours, contributing to empty calories,” said Girish Ganjyal, a professor and food processing specialist in WSU’s School of Food Science. “We wanted to see if it’s ...
Beyond the gut: A new frontier in IBS treatment by targeting the brain
2025-02-05
Irritable bowel syndrome (IBS) is a common digestive disorder that affects the intestine, causing symptoms such as abdominal pain, bloating, gas, and changes in bowel habits, including diarrhea, constipation, or both. Although this condition affects about a tenth of the global population, the underlying causes and mechanisms of IBS remain unclear. Consequently, treatments for IBS primarily focus on managing symptoms rather than addressing the root cause of the disorder.
At Tokyo University of Science ...
New spin on quantum liquids: Quasi-1D dynamics in molecular spin systems
2025-02-05
Quantum spin liquids (QSLs) are fascinating and mysterious states of matter that have intrigued scientists for decades. First proposed by Nobel laureate Philip Anderson in the 1970s, these materials break the conventional rules of magnetism by never settling into a stable magnetic state, even at temperatures close to absolute zero. Instead, the spins of the atoms within them remain constantly fluctuating and entangled, creating a kind of magnetic “liquid.” This unusual behavior is driven by a phenomenon called magnetic frustration, where competing forces prevent the system from reaching a single, ordered configuration. QSLs are notoriously ...
Spinal cord stimulation restores neural function, targets key feature of progressive neurodegenerative disease
2025-02-05
PITTSBURGH, Feb. 5, 2025 – A new drug-free, minimally invasive intervention targets the root cause of progressive loss of neural function in spinal muscle atrophy (SMA), an inherited neuromuscular disease. An intervention, which involves electrical stimulation of the sensory spinal nerves, can gradually reawaken functionally silent motor neurons in the spinal cord and improve leg muscle strength and walking in adults with SMA. The findings were reported by University of Pittsburgh School of Medicine researchers in Nature Medicine today.
Early results from a pilot clinical trial in three human volunteers with SMA show that one month of regular ...
Shut the nano gate! Electrical control of nanopore diameter
2025-02-05
Osaka, Japan—A gate that can be open or shut to allow or block the passing of species on one or both sides applies not only on the macroscale, for example a farm gate used to control stock movement, but also at the nanoscale, where a gate can control the translocation of single molecules.
A collaboration headed by researchers at Osaka University has developed a nanogate that can be open or shut by applying electricity. The nanogate shows various behaviors depending on the materials in the solutions on both sides of the gate and the applied voltage, making it attractive for different applications including sensing and controlled chemical reactions.
The ...
Cutting emissions in buildings and transport: Key strategies for 2050
2025-02-05
Key findings: a roadmap to transform energy use by 2050
Electrification (e.g., switching to electric vehicles, heat pumps) alone could cut direct emissions by 45-77% in buildings and 22-86% in transport by 2050.
Combining electrification, efficiency improvements, and behavioral changes could reduce emissions even further: 51-85% for buildings and 37-91% for transport by 2050.
A multi-strategy approach would lower overall electricity demand by 8-33% per year, making the transition more cost-effective ...
How parents can protect children from mature and adult content
2025-02-05
Toronto, ON – As children's screen time continues to rise, so does their exposure to age-inappropriate content, including R-rated movies and violent video games. A new study published in BMC Pediatrics underscores the critical role parents play in shaping their children’s media consumption.
As child media consumption increases along with their exposure to mature media content, a new study finds that parent media practices play a key role in shaping preteens’ consumption of mature video games and R-rated movies.
Researchers found that parents’ own screen habits—such as using screens in front of their children and allowing screens during meals ...
By studying neutron ‘starquakes’, scientists hope to transform their understanding of nuclear matter

Investigators have found that a product called cellular concrete may be an environmentally friendly alternative to conventional concrete for constructing earthquake-resistant buildings.
In research published in Structural Concrete, the team analyzed the environmental impact of constructing a seven-story archetype residential building in Quito-Ecuador with cellular concrete, which is produced by incorporating a foaming agent that generates air pockets within the concrete matrix to decrease the material’s density while maintaining sufficient structural ...
How does light affect citrus fruit coloration and the timing of peel and flesh ripening?
2025-02-05
Citrus fruit rind color has long been used as an indicator of ripeness, but for some fruits such as mandarin fruit in the Chongqing region of China, the peel and flesh do not ripen synchronously, with the flesh usually reaching maturity while the peel is still green. This is a characteristic that seriously affects its commercial value. In new research published in the Journal of the Science of Food and Agriculture, investigators have discovered how red and blue LED light can stimulate color change in mandarin fruit.
Experiments showed that this light exposure causes ...
Male flies sharpened their eyesight to call the females' bluff
2025-02-05
With bloated bellies and hairy legs, female flies try to look bigger to get food from courting mates. But male flies, in turn, have sharpened their eyesight to call their bluff. A new study by researchers from the Universities of Gothenburg and Stockholm suggests that this is an ongoing evolution where both sexes try to outsmart each other.
For the first time, researchers have been able to show that also males can develop traits that help them pass on their genes despite the manipulative adaptations of the opposite sex. In different species of dance flies, there is a clear correlation between how richly decorated the female ...
School bans alone not enough to tackle negative impacts of phone and social media use
2025-02-05
Students attending schools that ban the use of phones throughout the school day aren’t necessarily experiencing better mental health and wellbeing, as the first worldwide study of its kind has found that just banning smartphones is not enough to tackle their negative impacts.
In a landmark study published today (Wednesday 5 Feb) in Lancet Regional Health Europe, 1227 students from 30 schools across England provided data about smartphone and social media usage and a range of mental health, wellbeing and other outcomes. ...
Explaining science in court with comics
2025-02-05
Imagine being summoned as a juror in a murder trial. The expert responsible for analyzing DNA traces at the crime scene has just explained that they match the defendant’s profile. “Then the culprit must be them,” you think. At this point, however, the expert adds: “The sample, however, is partially degraded.” What does this mean? How does this information affect your judgment? The scientist further explains that there is a one-in-a-billion probability that other people could match the identified genetic profile. ...
‘Living’ electrodes breathe new life into traditional silicon electronics
2025-02-05
Osaka, Japan – High-speed electronic devices that do not use much power are useful for wireless communication. High-speed operation has traditionally been achieved by making devices smaller, but as devices become smaller, fabrication becomes increasingly difficult. Have we reached a dead end?
Not yet! A research team at Osaka University is exploring another way to improve device performance: placing a patterned metal layer, i.e., a structural metamaterial, on top of a traditional substrate, e.g., silicon, to accelerate ...
One in four chance per year that rocket junk will enter busy airspace
2025-02-05
There’s a 26 per cent annual chance that space rocket junk will re-enter the atmosphere and pass through a busy flight area, according to a recent UBC study.
While the chance of debris hitting an aircraft is very low, the research highlights that the potential for uncontrolled space rocket junk to disrupt flights and create additional costs for airlines and passengers is not.
Space junk disrupting air traffic is far from unheard of. In 2022, a re-entering 20-tonne piece of rocket prompted Spanish and French aviation authorities to close parts ...
Later-onset menopause linked to healthier blood vessels, lower heart disease risk
2025-02-05
Women who go through menopause later in life have healthier blood vessels for years to come than those who go through it earlier, according to new University of Colorado Boulder research.
The study, published in the American Heart Association journal Circulation Research, offers new insight into why females who stop menstruating at age 55 or later are significantly less likely to have heart attacks and strokes in their postmenopausal years.
Arriving just in time for Women's Heart Health Month, in February, the findings could help lead to new therapies, including dietary interventions, to reduce risk of heart ...
New study reveals how RNA travels between cells to control genes across generations
2025-02-05
RNA-based medicines are one of the most promising ways to fight human disease, as demonstrated by the recent successes of RNA vaccines and double-stranded RNA (dsRNA) therapies. But while health care providers can now successfully develop drugs that use dsRNA to accurately target and silence disease-causing genes, a major challenge remains: getting these potentially life-saving RNA molecules into cells efficiently.
A new study published in the journal eLife on February 4, 2025, may lead to breakthroughs in RNA-based drug development. University of Maryland researchers used microscopic roundworms ...
Women health sector leaders good for a nation’s wealth, health, innovation, ethics
2025-02-05
Women health sector leaders are good for a nation’s wealth, health, innovation, and ethics, among other things, finds a review of the available evidence, published in the open access journal BMJ Global Health.
Yet despite their unique and positive impact, they are a major underused resource, particularly in low and middle income countries, say the researchers, who call for more and sustained investment to maximise women’s potential and reap the benefits of their contribution.
Despite making up 70% of the healthcare workforce, as a whole, and 90% of the nursing ...
‘Good’ cholesterol may be linked to heightened glaucoma risk among over 55s
2025-02-05
‘Good’ (HDL) cholesterol, usually considered to be beneficial for health, may be linked to a heightened risk of the serious eye condition, glaucoma—at least among the over 55s— suggest the results of a large observational study, published online in the British Journal of Ophthalmology.
Paradoxically, ‘bad’ (LDL) cholesterol, usually regarded as harmful to health, may be associated with a lower risk of glaucoma, a condition that damages the optic nerve, potentially leading to irreversible sight ...
GLP-1 drug shows little benefit for people with Parkinson’s disease
2025-02-05
The GLP-1 drug, exenatide, has no positive impact on the movement, symptoms or brain imaging of people with Parkinson’s, finds a new study led by UCL researchers.
The world’s largest and longest trial of exenatide in people with Parkinson’s disease was funded by the National Institute for Health & Care Research (NIHR) with support for sub-studies from Cure Parkinson’s and Van Andel Institute.
For their research, published in The Lancet, the team designed a randomised controlled phase 3 trial to definitively determine whether exenatide use was associated with any benefit in people with Parkinson’s and ...
Generally, things really do seem better in morning, large study suggests
2025-02-05
Generally, things really do seem better in the morning, with clear differences in self-reported mental health and wellbeing across the day, suggest the findings of a large study published in the open access journal BMJ Mental Health.
People generally wake up feeling in the best frame of mind in the morning but in the worst around midnight, the findings indicate, with day of the week and season of the year also playing their part.
Mental health and wellbeing are dynamic in nature, and subject to change over both short and extended periods, note the researchers. But relatively few studies have looked at how these might change over the course of the day, and those studies that ...
