For thousands of years, horses and donkeys have been some of our species' most important partners.
Tonnes of dead fish have washed up on the shore of a highly polluted lake in eastern Lebanon in the past few days, an official said Thursday.
The failure to halt climate change, the destruction of nature and other intertwined global crises poses an existential risk to humanity, ten Nobel laureates said Thursday following the first-ever Nobel Prize Summit.
NASA's Mars Ingenuity helicopter missed its fourth scheduled flight on Thursday, with the space agency blaming a software glitch and vowing to try again the next day.
Research-practice partnerships (RPPs), long-term collaborations between researchers, policy makers and practitioners, represent an especially promising strategy for making sure that all children benefit from early childhood education, according to a journal released today by Princeton University and the Brookings Institution.
A new study led by University of Minnesota astrophysicists shows that high-energy light from small galaxies may have played a key role in the early evolution of the Universe. The research gives insight into how the Universe became reionized, a problem that astronomers have been trying to solve for years.
In August 2016 a massive storm on par with a Category 2 hurricane churned in the Arctic Ocean. The cyclone led to the third-lowest sea ice extent ever recorded. But what made the Great Arctic Cyclone of 2016 particularly appealing to scientists was the proximity of the Korean icebreaker Araon.
Tomorrow's cutting-edge technology will need electronics that can tolerate extreme conditions. That's why a group of researchers led by Michigan State University's Jason Nicholas is building stronger circuits today.
Archeologists have learned a lot about our ancestors by rummaging through their garbage piles, which contain evidence of their diet and population levels as the local flora and fauna changed over time.
A gardener hoping for a crop of the juiciest summer tomatoes might tend to each and every plant in a plot. But a farmer working to feed the world?
Researchers in the materials department in UC Santa Barbara's College of Engineering have uncovered a major cause of limitations to efficiency in a new generation of solar cells.
An international team led by Xiangming Xiao, George Lynn Cross Research Professor in the Department of Microbiology and Plant Biology, University of Oklahoma College of Arts and Sciences, published a paper in the April issue of the journal Nature Climate Change that has major implications on forest policies, conservation and management practices in the Brazilian Amazon. Xiao also is director of...
Mantis shrimp don't need baby food. They start their life as ferocious predators who know how to throw a lethal punch.
The genome of single-celled plankton, known as dinoflagellates, is organized in an incredibly strange and unusual way, according to new research. The findings lay the groundwork for further investigation into these important marine organisms and dramatically expand our picture of what a eukaryotic genome can look like.
Forget diamonds—plastic is forever. It takes decades, or even centuries, for plastic to break down, and nearly every piece of plastic ever made still exists in some form today. We've known for a while that big pieces of plastic can harm wildlife—think of seabirds stuck in plastic six-pack rings—but in more recent years, scientists have discovered microscopic bits of plastic in the water,...
Parallel evolution is common, but do different animal populations evolve in similar ways and alter the same genes to adapt to similar environmental conditions? Researchers tested this in two U.S. populations of house mice. They found independent evolution of a heavier body and larger nests as Eastern and Western populations invaded northern habitats after introduction from Europe. Many of the same...
An experimental treatment produced improvements in cognitive function and language in patients with fragile X syndrome, according to new study results.
A new genetic database for autoimmune and autoinflammatory diseases will allow experts to more deeply understand how immune disorders develop and plan future drug discovery projects. Scientists also hope this atlas of immune-related genome data may eventually be applied to investigations of infectious diseases like COVID-19.
Research has shed new light on the impact of humans on Earth's biodiversity. The findings suggest that the rate of change in an ecosystem's plant-life increases significantly during the years following human settlement, with the most dramatic changes occurring in locations settled in the last 1500 years.
Particularly sensitive to chemical modifications, mRNAs are molecules responsible for transmitting the information encoded in our genome, allowing for the synthesis of proteins. Two teams have focused on a specific type of chemical modification - called methylation - of mRNA molecules in the small worm Caenorhabditis elegans. They found that methylation on a particular sequence of an mRNA leads to...
Researchers have discovered a mechanism through which meningitis-causing bacteria can evade our immune system. In laboratory tests, they found that Streptococcus pneumoniae and Haemophilus influenzae respond to increasing temperatures by producing safeguards that keep them from getting killed. This may prime their defenses against our immune system and increase their chances of survival, the...
Scientists have been able to track how a multi-drug resistant organism is able to evolve and spread widely among cystic fibrosis patients - showing that it can evolve rapidly within an individual during chronic infection. The researchers say their findings highlight the need to treat patients with Mycobacterium abscessus infection immediately, counter to current medical practice.
