Surfing: are we developing antibiotic resistance | Photo: Sam Swanson/Creative Commons

Surfers Against Sewage (SAS) have teamed up with scientists from the University of Exeter Medical School to study how wave riders exposed to water pollution might be affected by antibiotic-resistant bacteria.

The innovative study is calling on surfers across the United Kingdom to help by providing samples gathered from rectal swabs. Initially, it can sound quite uncomfortable, but the goal is absolutely valid.

"We know that surfers regularly swallow lots more seawater than other beach users - around 170 ml per session, which is more than 10 times that of sea swimmers," explains Anne Leonard, one of the researchers behind the "Beach Bums" study.

Deep-Z: a 3D-printed submarine

A small 3D-printed submarine survived a 200-meter (656.16 feet) dive into the depths of Lagos d'Iseo, in Italy.

Martin Baumers, the scientist behind the Deep-Z project, wanted to know if 3D printing can be used to build low-cost devices for deep water exploration.

To start his experimentations, the researcher build the submarine model using Polyamide 12, also known as Nylon 12, as the standard material. This is a very strong material often used in airplanes, cars and medical products.

The 25th annual Beach Report Card reveals that Cowell Beach, at the wharf in Santa Cruz County, is considered the worst spot and the most polluted beach of the 2014/2015 season.

According to Heal the Bay, only 13 of the beaches monitored statewide received D to F grades during summer dry weather, when most beachgoers typically use the ocean.

High bacteria counts at these sites are linked to potential illnesses like stomach flu, ear and upper respiratory infections and major skin rashes.
