Researchers develop realistic system to study impact of residential mold on health

A team of Danish investigators has created a modeling system that actually mimics indoor fungal aerosols, studying the impact of residential mold on human health. The system, published in Applied and Environmental Microbiology, contains at least eleven species of fungus associated with water damage, found in both Danish and US buildings.

Preventing protein unfolding

Researchers at Northwestern University have designed a way to prevent protein unfolding under mechanical stress, which causes devastating neurodegenerative diseases. By attaching polymers to proteins, they can stabilize their shape and prevent them from unfolding even when subjected to large forces.

Solar cells as light as a soap bubble

Researchers at MIT have developed a new approach to making solar cells, resulting in the thinnest and lightest complete solar cells ever made. The new process enables the creation of ultra-thin, flexible solar cells that can be integrated into various materials or surfaces, opening up new possibilities for portable electronic devices.

Clinical community crucial in the future of mitochondrial replacement, say experts

The US medical community will play a key role in determining the ethically acceptable path forward for clinical application of mitochondrial replacement techniques (MRTs). MRTs aim to prevent certain debilitating diseases related to mutated mitochondrial DNA by replacing a mother's mtDNA with that of another woman. The first use of MRT...

New trigger for self-powered mechanical movement

A team of researchers at Penn State University and the University of Pittsburgh has developed a new way to use enzyme reactions to trigger self-powered mechanical movement. The enzyme pumps can precisely control flow rate without an external power source and turn on in response to specific chemicals in solution.

Tests show no specific gastrointestinal abnormalities in children with autism

A recent study published in the Journal of Pediatric Gastroenterology and Nutrition found that children with autism do not have a unique pattern of abnormal results on endoscopy or other tests for gastrointestinal disorders. The researchers analyzed the results of diagnostic tests in 61 children with autism being evaluated for GI sympt...
