Study in India shows kids use different math skills at work vs. school
2025-02-05
In India, many kids who work in retail markets have good math skills: They can quickly perform a range of calculations to complete transactions. But as a new study shows, these kids often perform much worse on the same kinds of problems as they are taught in the classroom. This happens even though many of these students still attend school or attended school through 7th or 8th grades.
Conversely, the study also finds, Indian students who are still enrolled in school and don’t have jobs do better on school-type math problems, but they often fare poorly at the kinds of problems that occur in marketplaces.
Overall, both the “market kids” and the “school kids” ...

Why antibiotics can fail even against non-resistant bacteria
2025-02-05
Antibiotics are indispensable for treating bacterial infections. But why are they sometimes ineffective, even when the bacteria are not resistant? In their latest study published in the journal Nature, researchers from the University of Basel challenge the conventional view that a small subset of particularly resilient bacteria are responsible for the failure of antibiotic therapies.
In certain infectious diseases caused by bacteria, antibiotics are less effective than expected. One example is infections caused by Salmonella bacteria, which can lead to illnesses such ...
Missing link in Indo-European languages' history found
2025-02-05
Where lies the origin of the Indo-European language family? Ron Pinhasi and his team in the Department of Evolutionary Anthropology at the University of Vienna contribute a new piece to this puzzle in collaboration with David Reich's ancient DNA laboratory at Harvard University. They analyzed ancient DNA from 435 individuals from archaeological sites across Eurasia between 6.400–2.000 BCE. They found out that a newly recognized Caucasus-Lower Volga population can be connected to all Indo-European-speaking populations. The new ...
Cancer vaccine shows promise for patients with stage III and IV kidney cancer
2025-02-05
Boston – Dana-Farber Cancer Institute researchers report that all nine patients in a clinical trial being treated for stage III or IV clear cell renal cell carcinoma (a form of kidney cancer), generated a successful anti-cancer immune response after initiation of a personalized cancer vaccine. The vaccines were administered after surgery to remove the tumor and are designed to train the body’s immune system to recognize and eliminate any remaining tumor cells. At the time of data cut-off (median of 34.7 months), ...
Only seven out of 100 people worldwide receive effective treatment for their mental health or substance-use disorders
2025-02-05
New research estimates that globally, only 6.9 per cent of people with mental health or substance-use disorders receive effective treatment for their disorders.
Researchers from the University of British Columbia and Harvard Medical School analyzed survey data from nearly 57,000 participants in 21 countries collected over a 19-year period, to provide the clearest picture yet of where people discontinue their path to effective treatment for nine common anxiety, mood and substance-use disorders.
The biggest barrier to effective ...
Ancient engravings shed light on early human symbolic thought and complexity in the levantine middle palaeolithic
2025-02-05
New study demonstrates that certain incised stone artefacts from the Levantine Middle Palaeolithic, specifically from Manot, Qafzeh, and Quneitra caves, were deliberately engraved with geometric patterns, indicating advanced cognitive and symbolic behaviour among early humans. In contrast, artefacts from Amud Cave, with shallow and unpatterned incisions, are consistent with functional use. This research highlights the intentionality behind the engravings, providing key insights into the development of abstract thinking and the cultural complexity of Middle Palaeolithic societies.

The sexes have different strengths for achieving their goals
2025-02-05
Many factors are needed to achieve our goals. Now researchers have looked at passion, drive and people’s ability to find flow.
“This is the first study to look at these factors together,"says Professor Hermundur Sigmundsson at the Norwegian University of Science and Technology (NTNU’s) Department of Psychology.
The researchers have found differences between the sexes. The results indicate that the sexes each have their own strengths when it comes to success.
Men are more passionate than women when it comes to achieving their goals. They also often have an easier time finding flow.
Women, ...
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
2025-02-05
The study of ‘starquakes’ (like earthquakes, but in stars) promises to give us important new insights into the properties of neutron stars (the collapsed remnants of massive stars), according to new research led by the University of Bath in the UK.
Such explorations have the potential to challenge our current approaches to studying nuclear matter, with important impacts for the future of both nuclear physics and astronomy. Longer term, there may also be implications in the fields of health, security and energy.
The value of studying asteroseismology – as these vibrations and flares are known – has emerged from research carried ...
Mouth bacteria may hold insight into your future brain function
2025-02-05
The bacteria in your mouth and on your tongue may be linked to changes in brain function as you age, new research suggested.
The study, led by the University of Exeter, found that certain bacteria were associated with better memory and attention, while others were linked to an increased risk of Alzheimer’s disease.
The researchers identified two possible ways these bacteria may impact brain health. This includes harmful bacteria directly entering the bloodstream, potentially causing damage to the brain. Alternatively, an imbalance between beneficial and harmful bacteria can reduce the conversion of ...
Is cellular concrete a viable low-carbon alternative to traditional concrete for earthquake-resistant structures?
2025-02-05
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. ...
