A wafer of polyethylene

Researchers have created ultrathin polymer films made of nanocrystals using a novel production technique. The method, led by Stefan Mecking, produces films with a thickness of 50 nm using individual prefabricated nanocrystal building blocks.

Parasitoid turns its host into a bodyguard

A parasitoid wasp induces its moth caterpillar host to stop feeding, remain close to the pupae, and defend against predators, resulting in increased pupae survival. The caterpillar's behavioral changes appear to outweigh potential risks of increased transmission for the parasite.

Can we 'wipe out' MRSA?

A study by Cardiff University found that current hospital protocols for antimicrobial wipes can spread pathogens like MRSA. Implementing a single-use, one-surface-per-wipe approach could reduce MRSA incidence in hospitals.

Firearm suicide and homicide rates associated with level of background check

A new study published in the American Journal of Preventive Medicine found that local-level background checks are associated with a 27% lower firearm suicide rate and a 22% lower homicide rate compared to federal-level checks. States that rely on local-level checks have substantially lower rates of firearm suicides and homicides.

Holistic understanding: Ag chemicals in the environment

The USGS conducted a holistic study on agricultural chemicals in the environment, collecting field data and employing numerical models to simulate water and chemical transport. The results show that modifications to agricultural practices can profoundly alter chemical transport rates, affecting contaminant dilution and transformation.

Low vitamin D levels appear common in healthy children

A study of 380 healthy children found that nearly half had low vitamin D levels, and about one-third showed reduced bone mineral content on X-rays. The researchers suggest that all young children should receive vitamin D supplements to prevent potential health issues.

Metformin increases pathologic complete response rates in breast cancer patients with diabetes

Researchers found that metformin significantly increased pathologic complete response rates in diabetic women with early-stage breast cancer who took the drug during chemotherapy. The study showed a 24% response rate, three times higher than non-diabetic patients. Further investigation is needed to understand the mechanism of the drug.

Exposure therapy may help prevent post-traumatic stress disorder

A randomized controlled trial found that exposure therapy was more effective than cognitive restructuring in preventing PTSD in individuals with acute stress disorder. Exposure therapy reduced distress ratings and promoted full remission, suggesting its potential as an early intervention for high-risk patients.
