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.

Researchers report a surprising link between mitochondria, inflammation and gene mutations that may increase risk of atherosclerosis.

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).

Researchers discovered two signaling pathways that are downregulated in human hearts after birth.

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 impacts of runoff and wastewater that flow into the sea.

A new study reveals a unique form of cell communication that controls muscle repair.

Cardiomyopathy is not a uniform disease. Rather, individual genetic defects lead to heart failure in different ways, an international consortium reports.

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 understand the vast non-coding part of our genome that contains most disease-associated mutations.

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 observations turned up no obvious signs that hybrids fare any worse than their counterparts. But the new findings suggest that appearances can be...

Investigators have identified a component in the intestine that plays a critical role in repairing damaged tissue.

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 have, for the first time, applied their understanding of artillery shells to explain this unique movement, creating the most precise model to date of...

Scientists and engineers have developed a one-step method involving sandpaper and powder to make robust superhydrophobic materials.

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.

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 disease, cannot metabolize lipids normally, leading to a buildup of excess lipids that interferes with nearby neurons' ability to communicate with each...

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 engineered Escherichia coli strain. The strategies will be also useful for the efficient production of other industrially important natural products...

The production of ammonia, a major ingredient in fertilizers, involves greenhouse gas emissions. Scientists have quantified ways to reduce carbon impacts in this process.

To monitor heart rhythms and muscle function, doctors often attach electrodes to a patient's skin, detecting the electrical signals that lie beneath. These impulses are vital to the early diagnosis and treatment of many disorders, but currently available electrodes have limited function or are expensive to manufacture. Researchers however, have now developed a low-cost, spongy version with...

From the wide variety of sodas, candies and baked goods that are sold worldwide, it's clear that people love their sweet treats. But consuming too much white table sugar or artificial sweetener can lead to health issues. In the search for a better sweetener, researchers now report a low-calorie mixture that is as sweet as table sugar and, in lab experiments, feeds 'good' gut microbes.

A team of researchers have injected parasitic worms into mice to study how injured cells trigger an immune response.

Researchers have been able to successfully teach microrobots how to swim via deep reinforcement learning, marking a substantial leap in the progression of microswimming capability.

The pandemic has called attention to an issue that nursing home residents, their families and those who work in nursing homes have been aware of for a long time. Recruiting and retaining both the nursing home staff who provide the very personal care needed by residents and the administrators who set the tone of the workplace are key challenges in nursing homes. Regenstrief Institute and Indiana...

Investigators have identified genetic signatures that could predict whether tumors in patients with bladder and other cancers will respond to immunotherapy.

Accurate, continuous monitoring of nitrogen dioxide and other gases in humid environments is now possible, thanks to a new water-resistant gas sensor.

Scientists have long tried to introduce genetically engineered bacteria into the gut to treat diseases. In the past, these attempts have focused on engineering common lab strains of E. coli, which cannot compete with the native gut bacteria that are well adapted to their host. Now, a group of researchers successfully engineered E. coli collected from both human and mice gut microbiomes and showed...
