00:55 Graphene tongue
Researchers have developed a graphene ‘tongue’ that makes use of AI to inform the delicate variations between drinks. Graphene has lengthy been wanted as a chemical sensor, however tiny variations between units have meant that it couldn’t be used very reliably. The staff behind the ‘tongue’ obtained round this drawback by coaching an AI to inform the distinction between comparable liquids no matter variations between graphene units. They hope that their work reveals that it’s doable to make use of ‘imperfect’ chemical sensors to get correct readings and that the ‘tongue’ will be capable to assist detect issues with meals.

09:22 Analysis Highlights
A 3D-printed optical microscope that may picture organic samples with ultrahigh decision, and the way newly hatched sea turtles dig their means as much as the seaside.
Analysis Spotlight: A ‘Swiss military knife’ microscope that doesn’t break the financial institution

11:32 How migrating salmon transfer vitamins and contaminants at a continental scale
Research of migrating Pacific salmon have revealed that these animals transport hundreds of tonnes of vitamins and kilograms of contaminants from the ocean to freshwater ecosystems. It’s been recognized that because the fish return to their freshwater spawning grounds from the ocean they carry with them each vitamins and contaminants, however the affect of every has largely been studied individually. A brand new examine combines knowledge units to estimate that over 40 years, the degrees of vitamins these fish carry have elevated at a proportionally larger charge than the contaminants, however the contaminants might nonetheless be current at regarding ranges to the animals that eat them.
