| Sulfur 'spices' alien atmospheres Posted: 06 Apr 2020 11:01 AM PDT They say variety is the spice of life, and now new discoveries suggest that a certain elemental 'variety' -- sulfur -- is indeed a 'spice' that can perhaps point to signs of life. |
| Insect wings hold antimicrobial clues for improved medical implants Posted: 06 Apr 2020 07:38 AM PDT Some insect wings such as cicada and dragonfly possess nanopillar structures that kill bacteria upon contact. However, to date, the precise mechanisms that cause bacterial death have been unknown. Using a range of advanced imaging tools, functional assays and proteomic analyses, a study by the University of Bristol has identified new ways in which nanopillars can damage bacteria. |
| Making stronger concrete with 'sewage-enhanced' steel slag Posted: 06 Apr 2020 06:28 AM PDT Researchers examined whether steel slag that had been used to treat wastewater could then be recycled as an aggregate material for concrete. Their findings? Concrete made with post-treatment steel slag was about 17% stronger than concrete made with conventional aggregates, and 8% stronger than raw steel slag. |
| Cold War nuclear bomb tests reveal true age of whale sharks Posted: 06 Apr 2020 06:28 AM PDT Atomic bomb tests conducted during the Cold War have helped scientists for the first time correctly determine the age of whale sharks. |
