Researchers predicted dangerous heat waves will be significantly more common in future decades due to climate change. Exposure to harmful heat could double by 2100, leaving people in tropical regions with dangerous temperatures nearly every day, and heat waves will occur annually in cooler climates.
Scientists learned that X-shaped radio galaxies may not be as rare as they thought after unintentionally creating one in a lab. The shape appears to stem from gas falling into a black hole, causing particle jets to alter the galaxy’s shape. That’s much simpler than earlier theories had proposed.
Researchers found bumblebees aren’t all adjusting well when they emerge from hibernation. Those that awaken before spring flowers appear have more trouble finding food sources, which could put bumblebees and the plants they pollinate in danger as the climate changes.
NASA engineers remotely fixed a glitch in Voyager I. In May, the spacecraft began sending garbled data back to NASA instead of status reports. That resulted from Voyager sending the data through a non-functioning computer, which engineers fixed from 14.6 billion miles away. What caused the mishap is still unknown.
Researchers found Elkhorn coral can pass genetic mutations in non-reproductive cells to offspring, contrary to the current understanding of evolution. The finding suggests coral’s reproductive and non-reproductive cells aren’t separate as they are in other animals, enabling a previously unknown way to pass down mutations.
