[ad_1] Any biological sample, such as dirt, water or food, contains billions of bacteria. Only a few are harmful to humans or pathogenic. But those few pathogens can make the difference between a reliable supply of meat or lettuce, for example, and a food poisoning epidemic or, worse, a pandemic. …

(Photo credit: Benedikt Gunnar Ófeigsson, Icelandic Meteorological Office) A long-standing mystery involving floods or “jökulhlaup” emerging suddenly and unpredictably from glaciers or ice caps was fortuitously solved by a …

[ad_1] Scientists have developed an optical elastography technique that could revolutionize the accuracy and ease with which healthcare professionals can detect biomechanical changes in cells and tissues. A study derived from an international collaboration between the University of Exeter, the Gloucestershire Hospitals NHS Foundation Trust, the University of Perugia (Italy) …

(Credit: Zosia Rostomian / Berkeley Lab) Despite advances in sequencing technologies and computational methods over the past decade, researchers have discovered genomes …

[ad_1] A new model shows how the brine on Jupiter’s moon Europa can migrate inside the frozen shell to form pockets of salt water that erupt to the surface when it freezes. The findings, important for the upcoming Europa Clipper mission, could explain cryo-volcanic eruptions through the frozen bodies of …

[ad_1] According to new research involving the University of Plymouth, animal groups consider multiple factors before deciding whether to fight rivals. Before one-on-one fights, animals are known to make decisions based on factors including the size and strength of the opponent, the outcome of recent fights, and the importance of …

[ad_1] The universe is getting hotter, a new study has discovered. The study, published Oct.13 in the Astrophysical Journal, probed the thermal history of the universe over the past 10 billion years. He found that the average gas temperature in the universe increased more than 10 times over that time …

[ad_1] The fast, low-cost technique is the first to analyze DNA left in animal feces to map complex networks of species interactions in a terrestrial system. It could help redefine conservation as we know it, identify otherwise hard-to-find species, and lead a global effort to restore large areas. Watch the …

[ad_1] Metal-organic structures (MOFs) are a class of porous and crystalline materials that are synthesized from inorganic metal ions or clusters attached to organic ligands. Two of these materials are shown, HKUST-1 and MIL-100 (Fe). (Credit: Tania Evans, Georgia Tech) An artificial intelligence technique, machine learning, is helping to accelerate …
