Hardcore birders and casual sparrow spotters: Science needs you
Ornithologists are seeking volunteers in California, Oregon and Washington for Project Phoenix, a multiyear project exploring birds' response to wildfire.
Foreign, feral honeybees are crowding out native bee species in southern California
Non-native, feral honeybees are crowding out native bee species in southern California — and it could have knock-on effects on local plants in need of pollination.
Researchers find a link between gut bacteria and genes in colitis flare-ups
The interaction between a common gene variant and gut microbes may trigger chronic inflammation in ulcerative colitis, new research suggests.
Great white sharks tracked off the Carolina coast
A group of migrating great white sharks are suddenly acting like tourists along the Carolina coast. But apparently there's nothing to fear. Meg Oliver explains.
Million animals, plants at risk of extinction due to human activities, U.N. report says

National Zoo reopens for the first time in 19 weeks
After shutting down due to the coronavirus pandemic, the National Zoo in Washington, D.C. reopened to the public for the first time in 19 weeks. Some indoor exhibits still remain...
Evolutionary history of imperiled salmon stocks
New technologies for analyzing DNA may transform how imperiled species are considered and managed for conservation protection, according to a study. These technologies can be applied to a wide range...
Larvaceans provide a pathway for transporting microplastics into deep-sea food webs
A new article shows that filter-feeding animals called giant larvaceans can collect and consume microplastic particles, potentially carrying microplastics to the deep seafloor.
Problems with DNA replication can cause epigenetic changes that may be inherited for several generations
Scientists reveal that a fault in the process that copies DNA during cell division can cause epigenetic changes that may be inherited for up-to five generations. They also identified the...
Injecting manure instead of spreading on surface reduces estrogen loads
With water quality in the Chesapeake Bay suffering from excess nutrients and fish populations in rivers such as the Susquehanna experiencing gender skewing and other reproductive abnormalities, understanding how to...
Are stem cells the link between bacteria and cancer?
A new mechanism of stomach gland regeneration reveals impact of Helicobacter pylori infection.
How the genome sets its functional micro-architecture
Scientists now show how DNA is organized into specific regions, and that this depends on a combination of genomic distance and the presence of the CTCF protein.
Surprising discovery about how neurons talk to each other
New findings challenge existing dogma that neurons release fixed amounts of chemical signal at any one time and could have implications for brain disorders including Parkinson's and schizhophrenia.
New technique overcomes genetic cause of infertility
Scientists have created healthy offspring from genetically infertile male mice, offering a potential new approach to tackling a common genetic cause of human infertility.
Gene that makes large, plump tomatoes identified
Farmers can grow big, juicy tomatoes thanks to a mutation in the cell size regulator gene that occurred during the tomato domestication process.
Engineering team images tiny quasicrystals as they form
What makes quasicrystals so interesting? Their unusual structure. Now scientists are actively pursuing this relatively new area of study.
