Plant-based ‘beef’ reduces CO2 emissions but threatens 1.5M ag jobs
Plant-based alternatives to beef have the potential to help reduce carbon dioxide emissions, but new economic models show their growth in popularity could disrupt the agricultural workforce, threatening more than 1.5 million industry jobs.
Mitochondrial DNA mutations linked to heart disease risk
Researchers report a surprising link between mitochondria, inflammation and gene mutations that may increase risk of atherosclerosis.
Cosmic Evolution Early Release Science Survey: Wide view of the early universe
New images from NASA’s James Webb Space Telescope show what may be among the earliest galaxies ever observed. The images were taken from the Cosmic Evolution Early Release Science Survey (CEERS).
Study finds two protein pathways downregulated in postnatal heart
Researchers discovered two signaling pathways that are downregulated in human hearts after birth.
Tracking nitrogen pollution
Tropical coastal ecosystems are among the most biodiverse areas on Earth. And they’re also on the front lines of effects caused by human activity. That’s why it’s becoming increasingly important, especially as human populations increase, to manage the …
Hyaluranic acid, a naturally occurring compound, awakens stem cells to repair damaged muscle
A new study reveals a unique form of cell communication that controls muscle repair.
How pathogenic gene variants lead to heart failure
Cardiomyopathy is not a uniform disease. Rather, individual genetic defects lead to heart failure in different ways, an international consortium reports.
Single-cell approaches and deep learning to map all stages of fruit fly embryo development
Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to different developmental defects and provides a path to u…
These baboons borrowed a third of their genes from their cousins
Genetic analyses of baboons in Kenya reveals that most of them carry traces of hybridization in their DNA. As a result of interbreeding, about a third of their genetic makeup consists of genes from another, closely-related species. Fifty years of obser…
Insight into how the intestine repairs damaged tissue
Investigators have identified a component in the intestine that plays a critical role in repairing damaged tissue.
Putting a new spin on the football spiral
Only a handful of researchers have studied why an American football flies in such a unique trajectory, rifling through the air with remarkable precision, but also swerving, wobbling, and even tumbling as it barrels downfield. Now, ballistics experts ha…
Water can’t touch this sanded, powdered surface
Scientists and engineers have developed a one-step method involving sandpaper and powder to make robust superhydrophobic materials.
Researchers discover major roadblock in alleviating network congestion
Researchers discovered that congestion control algorithms designed to ensure multiple users sending data over a network do so fairly are actually unable to avoid situations where some users are hogging all the bandwidth.
How microglia contribute to Alzheimer’s disease
A new study shows how a type of cells called microglia contribute to the slowdown of neuron activity seen in Alzheimer’s disease. The study found that microglia that express the APOE4 gene, one of the strongest genetic risk factors for Alzheimer’s dise…
Metabolically engineered bacterium produces lutein?
A research group has engineered a bacterial strain capable of producing lutein. The research team applied systems metabolic engineering strategies, including substrate channeling and electron channeling, to enhance the production of lutein in an engine…
New way to calculate environmental impact of ammonia production
The production of ammonia, a major ingredient in fertilizers, involves greenhouse gas emissions. Scientists have quantified ways to reduce carbon impacts in this process.
