"These seabirds actually use odours to find their way around in the world and to find food," said Matthew Savoca, of University of California, Davis.
"We found a chemical on plastic that these birds typically associate with food, but now it's being associated with plastic.
"And so these birds might be very confused - and tricked into consuming plastic as food.""

Formas mais rápidas de detecção de bactérias (Legionela)

Citando:
"A project supported by the Photonics Public Private Partnership under the European Commission's Horizon 2020 program is developing an optical sensor intended to spot the presence of Legionella bacteria in under one hour - a process said to normally take up to ten days of cultivation and analysis.
The Poseidon (from "plasmonic-based automated lab-on-chip sensor for the rapid in-situ detection of Legionella") consortium has received funding of over €4 million in support of its research into the use of surface plasmon resonance (SPR) phenomena in a fully automated platform for fast optical detection of L. pneumophila pathogens.
