Laser method promising for detecting trace chemicals in air

Researchers have developed a new laser-based method that can detect electric charges and chemicals of interest with unprecedented sensitivity. The new approach could one day offer a way to scan large areas for radioactive ...

Researchers develop 'vaccine' against attacks on machine learning

Researchers from CSIRO's Data61, the data and digital specialist arm of Australia's national science agency, have developed a world-first set of techniques to effectively 'vaccinate' algorithms against adversarial attacks, ...

New record: 3-D-printed optical-electronic integration

Optoelectronic integration offers a promising strategy to simultaneously obtain the merits of electrons and photons when they serve as information carriers, including high-density communication and high-speed information ...

Pulsed electron beams shed light on plastics production

Plastics are all around us—they make up our water bottles, trash bags, packing materials, toys, containers, and more. About 300 million tons of plastic are produced worldwide each year, yet the details of what goes on at ...

New microneedle technique speeds plant disease detection

Researchers have developed a new technique that uses microneedle patches to collect DNA from plant tissues in one minute, rather than the hours needed for conventional techniques. DNA extraction is the first step in identifying ...

Getting the oil out of befouled water

Oil and water are famously reluctant to mix fully together. But separating them completely—for example, when cleaning up an oil spill or purifying water contaminated through fracking—is a devilishly hard and inefficient ...

Major breakthrough to help clean up toxic PFAS pollution

A joint research project between the University of South Australia and Flinders University has developed a new technique to clean up toxic polyfluorinated alkyl substances (PFAS) from waterways.
