Hera Closes In on Asteroid Pair to Study the Impact Damage of NASA’s DART Strike - Gizmodo

For more than 150 years, scientists believed it was the earliest documented example of a solar storm interfering with human technology. There was just one glaring problem. The Victorian railway hadn’t even been built yet. The story appeared in the prestigious scientific journal Nature in 1871. According to the account, an intense magnetic storm on October 18, 1841, scrambled telegraph signals along the South Devon Railway. Unable to confirm that the tracks ahead were clear, railway officials held the 10:05 p.m. express at Exeter for 16 minutes.

Australian adults who completed the self-compassion meditation training reported significantly increased body appreciation, positive well-being and lower self-judgment. The benefits were still evident six weeks after the program concluded, and frequency of practice alone did not drive the size of change. The randomized controlled trial, published in the journal Mindfulness, involved 227 people aged 18 to 39 years. Participants in the intervention group undertook 20 minutes of daily self-compassion, while those in the control group remained on the waitlist.

Astronomers analyzing white dwarf stars have for the first time found a star that would appear green to human eyes, according to a new study. While for most stars, color is temperature-dependent and limited to a few hues, white dwarfs, which are the dense remnants of sun-like stars that have died, can glow in an incredible range of colors, said lead study author Mark Hollands, an astrophysicist at the University of Warwick, England, on Thursday. “The colors that normal stars can have are pretty much only orange, white or blue,” Hollands told CNN. “What we found is, for most white dwarfs, that’s the same as well. But there are some special cases where the physics in the outer layers of these stars are sufficiently strange that it causes actually quite big deviations in terms of their spectrum,” he said. These deviations are due to the interaction between the helium in their atmosphere and traces of other elements, which vary between white dwarfs, depending on what material has interacted with the star over the course of its lifetime.

A new genetic testing approach for sick children with immune conditions could slash diagnosis waiting times from 12 months to as little as two weeks, University of Queensland research has found. A study with Children's Health Queensland has shown a new genetic testing process for children with immune conditions could speed up diagnoses, fast-track treatments and save lives.
