When it comes to detecting biomarker chemicals in a person's body, sweat-analyzing sensors offer a less painful alternative to blood sampling. A new wearable sensor takes a unique approach to collecting that sweat, by mimicking cactus needles. Source of Article
Despite being related to the humble freshwater perch, the Atlantic goliath grouper grows to be huge – up to 8 feet long (2.4 m) and 800 lb (363 kg). Scientists have recently learned more about its behaviour, using a new multifunctional high-tech tag. Source of Article
Fatty liver disease is a condition linked to obesity and diabetes, and in turn often leads to further major complications. Researchers have now found a way to reverse the progression of the disease in mice, by quieting an overactive gene. Source of Article
Last year, DeepMind produced a stunning advance in scientific research, using its AI to predict the 3D structures of unique proteins. This technology now forms the basis of a new spin-off from parent company Alphabet, called Isomorphic Labs. Source of Article
Recent studies have shown how the compound celastrol can tackle obesity in mice, but with harmful side effects. A new understanding of how the compound works on a cellular level could allow these effects to be avoided. Source of Article
Amazon announced today that it is going ahead with its Project Kuiper, its rival to SpaceX's Starlink orbital global internet service, by launching a pair of prototype satellites into low-Earth orbit under an experimental license from the FCC. Source of Article
Scientists in Australia have made intriguing discoveries in the genomes of a range of animals. What was initially mistaken for dust on the slides turned out to be “microchromosomes” from an ancient ancestor, present in birds, reptiles and mammals. Source of Article
A landmark study has demonstrated how a brain implant can deliver targeted bursts of electrical stimulation to improve cognitive functions. In real-time the implant senses biomarkers of cognitive deficits and responds by stimulating specific brain regions. Source of Article
Facebook recently rebranded as Meta, with an eye toward the development of VR/AR tech. In one of its first projects since the announcement, it's collaborating with Carnegie Mellon University on the development of a touch-sensitive electronic skin. Source of Article
A team at the Georgia Institute of Technology have come up with a concept that would see bacteria shipped to Mars produce rocket fuel and liquid oxygen from atmospheric CO2 to power a spacecraft on its return journey to Earth. Source of Article
