Clean Syringes Often Unavailable in St. Petersburg, YSPH Research Finds

Russia’s HIV epidemic is among the fastest growing in the world and injection drug users who often share needles and other supplies are hardest hit. This occurs even though pharmacies are a legal source for clean syringes and can sell them without restriction.

A recent study led by the Yale School of Public Health and St. Petersburg State University mapped the city’s 965 pharmacies and compared their locations and density to HIV prevalence at the district level. (more…)

A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has discovered that microscopic bacteria have a lot in common with earthquakes — when it comes to their jolting movements.

In a new study published in the peer-reviewed Proceedings of the National Academy of Sciences, the scientists also report that a molecular “glue” produced by the bacteria to help them adhere to surfaces also acts as a sort of transportation lubricant, helping them move and organize into rudimentary social structures. These discoveries, they say, could lead to new ways to combat harmful microbes in the long term. (more…)
