Researchers at the University of North Carolina have created microscopic soft robots shaped like flowers that can change shape and behavior in response to their surroundings, just like living organisms do. These tiny "DNA ...

Depending on where you live in the United States, the meat you eat each year could be responsible for a level of greenhouse gas emissions that's similar to what's emitted to power your house.

When I first realized the scale of the challenge posed by neurodegenerative diseases, such as Alzheimer's, Parkinson's disease and amyotrophic lateral sclerosis (ALS), I felt simultaneously humbled and motivated. These disorders ...

Skoltech researchers have created a promising catalyst to speed up a chemical reaction producing clean hydrogen fuel from the urea contained in wastewater. While that process is known to be catalyzed by various forms of nickel, ...

Researchers have developed a novel application of histological staining to screen for ancient proteins in situ—within the fossil's microstructure—advancing the field of paleoproteomics by addressing long-standing challenges ...

Ten years ago, close to 200 nations signed the Paris Agreement, an international treaty designed to cut greenhouse gas emissions and curtail global warming. Under the treaty, most nations made a 15-year promise to reduce ...

Burning fossil fuels has elevated atmospheric carbon dioxide, causing massive changes in the global climate including extreme temperatures and weather events here in the Midwest. Meanwhile, human activities have increased ...

Scientists have long noted with interest that in one of nature's crucial chemical reactions—the oxygen evolution reaction—it is manganese, rather than more plentiful similar elements such as iron, that acts as the key ...

DeePFAS, a novel deep-learning model, streamlines large-scale non-targeted screening of "forever chemicals" (PFAS) by projecting raw MS2 spectra into a latent space of chemical features, offering a rapid, AI-driven solution ...

An international team of scientists has unveiled the most comprehensive model yet that explains how cells control the flow of materials in and out of their nuclei—solving one of biology's oldest mysteries. The breakthrough, ...

Once a sperm has broken through to an egg cell in order to fertilize it, the two cells need to hold together tightly. This occurs via a type of protein binding that is among the strongest in biology—and it is also unique.

Natural products derived from microorganisms are a promising source of new active ingredients, but are often produced only in very small quantities. A research team from the Helmholtz Institute for Pharmaceutical Research ...
