The International Union for Conservation of Nature (IUCN) Red List has been the standard for determining the effects of a changing world on biodiversity since it was founded in 1964. But a recent study has revealed that more than 200 bird species in six rapidly developing regions are at risk of extinction even though they are not included in the IUCN Red List.
Researchers from the University of California, Davis have discovered that an olfactory cue catches the attention of the birds and convinces them that marine plastic is food. In a recently published study in the journal Science Advances, the reason behind ocean-faring birds ingesting large amounts of plastic has been revealed: marine plastic debris emits the scent of a sulfurous compound that some seabirds have relied upon for thousands of years to tell them where to find food.
Engineers from the University of California San Diego have developed a self-healing magnetic ink that can be used to make batteries, electrochemical sensors, and wearable, textile-based electrical circuits. The devices can repair tears as wide as three millimeters. This is a record in the field of self-healing systems.
