A new analysis of satellite data finds that the record surge in atmospheric methane emissions from 2020 to 2022 was driven by increased inundation and water storage in wetlands, combined with a slight decrease in atmospheric hydroxide (OH).

In a new study, researchers have tackled a thorny problem: How do nutritional stress, viral infections and exposure to pesticides together influence honey bee survival? By looking at all three stressors together, the scientists found that good nutrition enhances honey bee resilience against the other threats. In a new study, researchers at the University of

Analyzing fossils can be difficult -- especially when they're so small that they can only be seen with a microscope. Researchers have now come up with a solution. Fossils don't always come in large, dinosaur-sized packages. Microfossils refer to a type of fossil that is so small, it can only be perceived with a microscope.

Researchers have found that antibiotic-resistant bacteria are fatter and shorter than their antibiotic-sensitive parental strains, and that these morphological changes correlate with changes in the expression of genes related to energy metabolism and antibiotic resistance. A machine learning approach was able to distinguish between antibiotic-resistant and antibiotic-sensitive bacteria in the absence of drug treatment based

Climate scientists and permafrost experts show that, according to new climate computer model simulations, global warming will accelerate permafrost thawing and as a result lead to an abrupt intensification of wildfires in the Subarctic and Arctic regions of northern Canada and Siberia. A study, published in the journal Nature Communications by an international team of

The skeletal remains of a senior officer of Sir John Franklin's 1845 Northwest Passage expedition have been identified using DNA and genealogical analyses.

Northeast Greenland is home to the 79 N Glacier -- the country's largest floating glacier tongue, but also one seriously threatened by global warming: warm water from the Atlantic is melting it from below. Experts have however now determined that the temperature of the water flowing into the glacier cavern declined from 2018 to 2021

It's almost time to dust off the Halloween decorations and adorn the house with all manner of spooky things, including the classic polyester spider webs. Scientists have made their own version of fake spider silk, but this one consists of proteins and heals wounds instead of haunting hallways. The artificial silk is strong enough to

Scientists have uncovered critical differences between how innate-like T cells mature in humans and mice. Early in life, most innate-like T cells in the human thymus aren't able to use all of their immune abilities. The discovery could point to better preclinical studies and, perhaps someday, a new form of immunotherapy. Our immune system spans

Scientists have shown that light pollution -- especially light in the blue spectrum -- can alter the behavior of fish after only a few nights, and have knock-on effects for their offspring.

A new study by more than 50 climate scientists worldwide provides the clearest projection that Antarctica's ice sheet will retreat rapidly after 2100 under current carbon emissions, with global sea levels rising by as much as 5.5 feet by 2200. The study combined 16 climate models and found that ice loss will gradually increase through

A biologist's groundbreaking research aims at improving global nutrition and sustainability. A Mississippi State biologist's groundbreaking research in improving global nutrition and sustainability is featured this week in New Phytologist. Ling Li, an associate professor in the MSU Department of Biological Sciences, has spent more than a decade studying rice and soybean crops, with the
