SITN Flash

Our “Science in the News Flash” is your twice-monthly source for information on recent high profile science issues. Most often, each issue of the SITN Flash features two articles. The SITN Flash also produces occasional special editions, such as a feature on the year of chemistry or the United Nations Decade on Biodiversity. These special editions contain multiple articles on a single topic, including current research as well as opinions and interviews of researchers in the field. SITNFlash is a free resource that can help you find easy-to-understand explanations of the science behind the hottest science stories you’ll read in newspapers and see on TV. By joining our email list, you will receive an update each time a new issue of the SITN Flash is released. Or follow us on Twitter @sitnflash

  • An Alternative to Antibiotics? NOVAMOXIN antibiotic from Bmramon at en.wikipediaScientists offer an alternative method to fight bacteria in an effort to combat antibiotic resistance.
