The agricultural use of antibiotics is contributing to the global spread of resistance to these life-saving medicines. What do we know about farming's role in the world's antibiotic resistance crisis and what are the critical outstanding questions? Adam Rutherford talks to Matthew Avison of the University of Bristol and Elizabeth Wellington of the University of Warwick.

A team at the Georgia Institute of Technology has built a record-breaking mechanical pump. The machine pumped molten tin at 1200 degrees Celsius continuously for 72 hours, and it has worked at even higher white hot temperatures. The pump is fabricated entirely from a heat-resistant ceramic material. Georgia Tech's Asegun Henry is developing the technology to transform the contribution that solar and wind energy generation can make in storing energy and supplying the electricity grid.

Caroline Steel reports on an opportunistic research project that used sound recordings to monitor biodiversity health in Singapore, when the island nation was engulfed in forest fire smoke haze in 2015.

Has the wreck of the first British ship to be sunk during World War II been found? Wreck-hunter David Mearns believes he's done so, using high-resolution sonar maps of the sea bed northwest of Ireland.
