Bedroom air filters help asthmatic children breathe easier

A new study finds that using bedroom air filters can significantly improve breathing in asthmatic children. Consistent daily use of filters for two weeks reduced airway resistance, lung inflammation, and increased airway elasticity. The findings suggest that the filters may help prevent asthma flare-ups without costly medications.

Potential early biomarker to track development of non-alcoholic fatty liver disease

Researchers from Joslin Diabetes Center have identified a potential early biomarker for non-alcoholic fatty liver disease (NAFLD), which is linked to the regulation of liver fat metabolism and fibrosis. The protein NREP was found to decrease in levels as NAFLD progressed, suggesting its role as an early indicator of the disease.

Innovative birds are less vulnerable to extinction

Bird species that exhibit novel foraging behaviors have reduced risk of extinction, according to a study published in Nature Ecology & Evolution. The researchers found that the more innovative a species is, the lower its risk of extinction, with some species able to adapt to habitat destruction by finding new food sources.

Changes in brain attention may underlie autism

Research suggests that individuals with autism spectrum disorder exhibit differences in attention regulation, which may be attributed to altered locus coeruleus activity. This study found that participants with autism displayed atypically smaller pupil dilations during a distraction task, indicating dysregulation in the brainstem.

Development of a sticker that indicates whether cold-chain food products have gone bad

A new sticker has been developed to indicate whether cold-chain food products have gone bad. The sticker changes color when exposed to room temperature, allowing users to determine if their food is spoiled. Its low manufacturing cost and flexibility make it suitable for widespread use in the fresh food delivery market.

What makes Saturn's atmosphere so hot

New analysis of data from NASA's Cassini spacecraft reveals that auroral electric currents are likely responsible for heating Saturn's upper atmosphere. The study provides the most complete mapping yet of temperature and density in a gas giant's upper atmosphere, shedding light on how heat circulates in the region.

A new way to deliver drugs in MOFs

Researchers at the IPC PAS and WUT have developed a new, solvent-free drug encapsulation method that uses a pre-assembled metal complex incorporating the drug molecule. This approach could dramatically improve the efficiency of drug encapsulation in MOF materials and open the way to formulating vast arrays of 'drug@MOF' composites.

New research suggests in-womb gene correction

Researchers at Oregon Health & Science University developed a synthetic molecule that targets and corrects a mutated gene causing Usher syndrome in mice. The technique may be used to deliver drug therapy through amniotic fluid to the fetus, potentially treating and preventing several types of congenital hearing and balance disorders.

The Lancet Public Health: US modelling study estimates impact of school closures for COVID-19 on US health-care workforce and associated mortality

A new modelling study published in The Lancet Public Health finds that school closures to reduce COVID-19 transmission may lead to increased childcare needs among healthcare workers, potentially compromising the system's response. Researchers estimate that up to 15% of health-care workers may need additional childcare, with certain occ...

Unsustainable food systems: Can we reverse current trends?

A new study found that only international trade has a net positive effect on global food systems sustainability, while population growth, urbanization, and lifestyle change have negative impacts. The study suggests that policymakers need better tools to measure and monitor food system dynamics to make them more sustainable.

Anterior insula activation restores prosocial behavior in animal model of opioid addiction

Researchers at Arizona State University found that activating the anterior insula restored prosocial behaviors in animals with opioid addiction, a potential breakthrough in treating social behavioral deficits. The study used chemogenetic methods to selectively activate the brain region involved in both prosocial and addictive behaviors.
