A New Radio Hit
Astronomers working with the CHIME telescope in Canada have detected the longest fast radio burst ever, clocking in at about 3 seconds. The bursts appear to feature a rhythm like a heartbeat, reports Ben Turner for Live Science. Fast radio bursts are mysterious radio signals, usually from faraway galaxies, whose origins remain under study. In 2020, researchers tracked the first fast radio burst detected within our own galaxy back to a magnetar, as Shannon Hall covered for Quanta.
That Smells Like It Looks Good
Researchers recently uncovered the network of brain connections behind a dog's powerful sense of smell. The map includes an unexpected tract not yet found in other animals that runs from the olfactory bulb to visual cortex, reports Laura Sanders for Science News. Smell has been one of the least understood senses. But in 2021, neuroscientists unveiled for the first time how olfactory receptors in insects recognize smells when odor molecules bind to them, as Jordana Cepelewicz reported for Quanta in 2021. | |
