Scientists at Oak Ridge National Laboratory and the University of Colorado Boulder used a gene-silencing tool and a large library of molecular guides to understand how photosynthetic bacteria adapt to light and temperature changes. They found that even partial suppression of certain genes yielded big benefits in modifying the stress response of wild microbes.
A new planning formula to optimise the lifecycle value of Australia鈥檚 warships in an era of geopolitical instability has been proposed by researchers at the University of South Au...
Cryogenic electron microscopy showed for the first time that large RNA complexes can assemble without the help of proteins, expanding our understanding of RNA folding and function.
Mount Sinai study suggests COVID-19 infection should be considered a risk factor for future cardiopulmonary conditions
Researchers at Children鈥檚 Hospital of Philadelphia (CHOP) highlighted the success of anaplastic lymphoma kinase (ALK) inhibition therapy in treating hereditary neuroblastoma, a rare subset of a common childhood cancer. Researchers suggest that the findings, published recently in JCO Precision Oncology, could help establish a new standard of care.
A new study from WashU Medicine examines the choices healthy research volunteers make when given the opportunity to learn their risk of developing Alzheimer鈥檚 disease dementia. The researchers found a large discrepancy between the percentage of participants who said they would like to learn their risk if such estimates became available and the percentage who followed through to learn those results when given the actual opportunity.
Researchers in China model the motions of groups of manta rays to study how group dynamics affect their propulsion, studying different formations of three manta rays: in tandem, in a triangular setup with one manta ray in front leading two behind, and in an inverse triangular configuration with one manta ray trailing the other two. They found the tandem formation only significantly increases propulsion for the middle manta ray, and the two triangular setups result in overall decreased efficiency compared to a single swimmer on its own. These findings can help optimize formations for underwater vehicle operations.
In this week鈥檚 JASA Express Letters, researchers in Japan capture sound fields around musical triangles. They wanted to understand the physical properties of the triangle instrument, test assumptions about the contribution of the triangle shape, and capture clear documentation through pictures of the sound waves around the triangle. Using acousto-optic imaging to study detailed characteristics of sound vibration pattern, the team found results that suggest resonance may occur in the triangle's semi-open space.
Recent artificial intelligence advances have largely focused on text, but AI increasingly shows promise in other contexts, including manufacturing and the service industry. In these sectors, targeted AI improvements can improve product quality and worker safety, according to a new study co-authored by an interdisciplinary team of experts from the University of Notre Dame.
A recent American Academy of Dermatology survey of more than 1,000 U.S. adults found that half worry about premature skin aging and only half use sunscreen regularly, while nearly 1 in 4 don鈥檛 know it helps prevent early aging.
