Turning waste plastic into carbon nanotubes to transmit electricity
(Swansea University) Scientists at Swansea University are extracting carbon atoms found in waste plastics and turning them into a nanotube format that can be used for the transmission of electricity. They are producing plastic electric cables without the copper wire inside them, which can be used in residential and industrial construction.The Welsh government is investing in the plastics upscaling project, which has the potential to create highly-skilled jobs in Wales.

Antibiotic resistance genes in three Puerto Rican watersheds after Hurricane Maria
(American Chemical Society) In the aftermath of Hurricane Maria, a category 5 hurricane that made landfall in September 2017, flooding and power outages caused some wastewater treatment plants (WWTPs) to discharge raw sewage into waterways in Puerto Rico. Six months later, researchers monitored antibiotic resistance genes (ARGs) in three Puerto Rican watersheds, finding that the abundance and diversity of ARGs were highest downstream of WWTPs. They report their results in ACS’ Environmental Science & Technology.
