When shopping online, participants surveyed spent more money, purchased more items, and spent less on candy and desserts than when they shopped in-store, according to a new study in the Journal of Nutrition Education and Behavior, published by Elsevier.

The spectacularly colorful aurora borealis -- or northern lights -- that fills the sky in high-latitude regions has fascinated people for thousands of years. Now, a team of scientists has resolved one of the final mysteries surrounding its origin.

Listed by the World Health Organization among the ten leading causes of medical disability worldwide, the severity of obsessive-compulsive disorder (OCD) is at a level on par with cancer. This prevalent disorder is characterized by highly distressing intrusive thoughts and repeated compulsive behaviours such as washing or checking.

Scientists from DICP of CAS fabricated new single-atom catalysis with good catalytic activity, selectivity and stability in reductive amination of biomass derived aldehydes/ketones to produce primary amines, and elucidated the structure-performance relationships from the atomic/molecular level.

Researchers designed and prepared a structured binder-free Ti-MWW catalyst via a combination method of shaping, recrystallization and chemical modification of active Ti sites. As a result, it had a ultra-long lifetime of 2400 h in a single HPPO run, during which the STY of PO was as high as 543 g kg-1 h-1, while the solvent consumption was only 194.3 kg kmol(H2O2)-1.

Children who consume too much sugar could be at greater risk of becoming obese, hyperactive, and cognitively impaired, as adults, according to the results of a new Australian study of mice led by QUT.

Forty years ago, the first cases of HIV/AIDS in the US began to raise public awareness -- but new research highlights the struggle people living with the disease still face against stigma, discrimination and negative labelling in their own families, communities and even amongst healthcare professionals.

A new study shows that pharyngeal jaws enable at least one species of moray eel to feed on land.

Scientists at Berkeley Lab and UC Berkeley have compiled the most complete library yet of lanthanide heavy metals and their potential toxicity -- by exposing baker's yeast to lanthanides. Their findings could help researchers uncover hidden pathways between lanthanide metals and disease.

Scientists have observed for the first time what it looks like in the key memory region of the brain when a mistake is made during a memory trial. The findings have implications for Alzheimer's disease research and advancements in memory storage and enhancement, with a discovery that also provides a view into differences between the physiological events in the brain during a correct memory versus a faulty one.

Experts suggest limited and careful use of corticosteroids as one of several strategies to curtail the syndemic of mucormycosis, or 'black fungus,' a fungal infection characterized by blackening or discoloration over the face, breathing difficulties, and other serious symptoms, that has recently emerged in India. A commentary from Washington University School of Medicine and the University of Massachusetts Medical School is published in Annals of Internal Medicine.

A new global study found that while death was uncommon among young COVID-19 patients, symptoms and complications were more prevalent than among youth with influenza.

Michigan hop growers contend with unique challenges as a result of frequent rainfall and high humidity during the growing season. In 2018, growers approached Michigan State University researchers and the Michigan State University's Plant & Pest Diagnostics lab with concerns about a leaf blight they had never seen before. This was followed by reports of hop cones shattering during harvest and yield losses in fields with the affected leaves.

Biomolecules regulate the biological functions inside every living cell. If scientists can understand the molecular mechanisms, then it is possible to detect severe dysfunction. At a molecular level, this can be achieved with fluorescent markers that are incorporated into the respective biomolecules. Researchers at the Universities of Göttingen and Edinburgh are now able to show that a complex of manganese makes it possible to conveniently label certain biomolecules. Results were published in Nature Communications.

The discovery, made possible by a partnership between a research group and a startup in São Paulo state (Brazil), could lead to novel treatments for intracranial hypertension and its complications, such as stroke.

A new study from the Peace and Conflict Neuroscience Lab at the Annenberg School for Communication found that Americans dramatically overestimate the number of migrants affiliated with gangs and children being trafficked, and that this overestimation contributes to dehumanization of migrants, lack of empathy for their suffering, and individuals' views on immigration policy. In addition, the researchers developed and tested interventions to address this misinformation and increase empathy for undocumented immigrants.

Building lights are a deadly lure for the billions of birds that migrate at night, disrupting their natural navigation cues and leading to deadly collisions. But even if you can't turn out all the lights in a building, darkening even some windows at night during bird migration periods could be a major lifesaver for birds.

Mandating vaccination could have a substantial negative impact on voluntary compliance, according to research published today in PNAS.

To describe something as slow and boring we say it's "like watching grass grow", but scientists studying the early morning activity of plants have found they make a rapid start to their day - within minutes of dawn.

A new technology could dramatically improve the safety and performance of lithium-ion batteries that operate with gas electrolytes at ultra-low temperatures. By keeping electrolytes from vaporizing, the technology can prevent pressure buildup inside the battery that leads to swelling and explosions.
