As authorities crack down on illicit drugs, experts have issued an alert on the use of the synthetic stimulant pentylone, as new research finds a 75% increase in detections across Australia.
Scientists have created a biocompatible artificial vitreous body derived from algae-derived carbohydrates.
Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels.
Barring a very few, most new-generation vaccines have a short duration of protection
Engineers aim to give robots a bit of common sense when faced with situations that push them off their trained path, so they can self-correct after missteps and carry on with their chores. The team's method connects robot motion data with the common sense knowledge of large language models, or LLMs.
Researchers have developed a novel sensor for the detection of bacteria. It is based on a chip with an innovative surface coating. This ensures that only very specific microorganisms adhere to the sensor -- such as certain pathogens. The larger the number of organisms, the stronger the electric signal generated by the chip. In this way, the sensor is able not only to detect dangerous bacteria with a high level of sensitivity but also to determine their concentration.
As cities around the world continue to draw young people for work, education, and social opportunities, a new study identifies characteristics that would support young urban dwellers' mental health. The findings, based on survey responses from a global panel that included adolescents and young adults, provide a set of priorities that city planners can adopt to build urban environments that are safe, equitable, and inclusive.
Air pollution and night-time outdoor light each were associated with harmful effects on brain health, finds new study.
GPT-4 can accurately interpret types of cells important for the analysis of single-cell RNA sequencing -- a sequencing process fundamental to interpreting cell types -- with high consistency compared to that of time-consuming manual annotation by human experts of gene information.
A study has identified a combination of medications that may improve blood flow within granulomas, benefiting drug delivery. The study leverages decades of cancer research to study tuberculosis-affected lung tissue and improve treatment.
When officials make tough calls on which areas to prioritize for conservation, biodiversity is often their top consideration. But there are several types of diversity, and not all of them overlap perfectly. In a new study, researchers analyzed 20-years' worth of U.S. Forest Service data and show that the simplest measure of diversity is the best predictor of healthy forest growth, providing a roadmap for quickly and efficiently protecting ecological resources.
Pairing cryptocurrency mining -- notable for its outsize consumption of carbon-based fuel -- with green hydrogen could provide the foundation for wider deployment of renewable energy, such as solar and wind power, according to a new study.
Researchers developed a method for 3D experiments that can reveal how forces are transmitted through granular materials, and how the shapes of the grains can dramatically change the outcomes. This could lead to better ways of understanding how landslides are triggered, and how to control the flow of granular materials in industrial processes.
A new study has found human brains are getting bigger. The increased size may lead to a brain reserve, potentially reducing the risk of dementia.
Many parents recognize increasing mental health concerns among children, reflected by the 1 in 5 who say they're open to allowing a child to take a mental health day.
For centuries, the Cerne Giant, a figure carved into a hillside in Dorset, has fascinated locals and visitors to the area. A new paper proposes that the Cerne Giant can in fact be dated to the early Middle Ages, and, as a result, its cultural context and significance more clearly understood.
New research has found that venetoclax, a medication currently approved for leukemia, has benefits for patients with multiple myeloma when used in combination with another drug. This discovery offers a new avenue of treatment options for the currently incurable disease.
Food insecurity among college students is associated with negative physical and mental health and lower academic performance and graduation rates. A recent research study investigates why over half of college students eligible for the Supplemental Nutrition Assistance Program (SNAP) -- the largest food assistance program in the US -- do not apply.
Pushing for a higher speed isn't just for athletes. Researchers, too, can achieve such feats with their discoveries. A new device called SCARF (for swept-coded aperture real-time femtophotography) can capture transient absorption in a semiconductor and ultrafast demagnetization of a metal alloy. This new method will help push forward the frontiers of knowledge in a wide range of fields, including modern physics, biology, chemistry, materials science, and engineering.
Researchers have provided fresh insight into the dangers some common household chemicals pose to brain health. They suggest that chemicals found in a wide range of items, from furniture to hair products, may be linked to neurological conditions.
