A study showing how ants tunnel their way through confined spaces could aid the design of search and rescue robots, say scientists.
A vaccine to protect sheep and cattle from a livestock virus spread by midges has been approved by government vets.
The latest data on EU bathing water quality is released, showing that 93% of more than 22,000 sampled locations meet the minimum standards.
Scientists have used plant samples collected in the 19th Century to identify the pathogen that caused the Irish potato famine.
UK astronaut Tim Peake is to fly to the International Space Station, launching on a Soyuz rocket in November or December 2015.
Strengthening biosecurity at UK borders and a plant health risk register would help protect the nation's trees from pests and diseases, a report concludes.
An international team of scientists reveals that a unique strain of potato blight they call HERB-1 triggered the Irish potato famine of the mid-19th century.
Bacteria resistant to the antibiotic colistin are also commonly resistant to antimicrobial substances made by the human body, according to a new study. Cross-resistance to colistin and host antimicrobials LL-37 and lysozyme, which help defend the body against bacterial attack, could mean that patients with life-threatening multi-drug resistant infections are also saddled with a crippled immune response.
NOAA presented to the U.S. Coast Guard a new report that finds that 36 sunken vessels scattered across the U.S. seafloor could pose an oil pollution threat to the nation's coastal marine resources. Of those, 17 were recommended for further assessment and potential removal of both fuel oil and oil cargo.
Researchers have found evidence of a major cosmic event near the end of the Ice Age. The ensuing climate change forced many species to adapt or die.
Women who smoke during pregnancy increase the risk of both obesity and gestational diabetes, in their daughters.
