The team’s ultrablack coating can be applied to curved surfaces and magnesium alloys to trap nearly all light. Credit: Jin et al. Sometimes, seeing clearly requires complete black. For astronomy and precision optics, coating devices in black paint can cut down on stray light, enhancing images and boosting performance. For the most advanced telescopes and … Read more
Credit: Pixabay/CC0 Public Domain A pair of planetary scientists, one with the University of Milan, the other with Columbia University, has found evidence that the exodus of hominins out of Africa approximately 1 million years ago may have been driven by the first major glaciation of the Pleistocene. In their study, reported in Proceedings of … Read more
Credit: Pixabay/CC0 Public Domain Wolverines could be poised for a comeback in California. A new bill seeks to reintroduce the solitary, muscular carnivores to the state’s mountainous regions, where they were hunted, poisoned and trapped into oblivion more than 100 years ago. Wolverines are exceedingly rare in the lower 48 states and received federal protection … Read more

Credit: CC0 Public Domain When media coverage doesn’t include the numerical magnitude of a scientific study’s effect, the risk of readers developing biases increases significantly, according to a new University of Michigan study. The study is published in the journal Psychological Science. People may incorrectly assume that the findings are of greater importance and impact … Read more
Dr. Laurie Gauger talks with students in her Speech Pathology Language Disorders class. Credit: Betsy Brzezinski One of life’s greatest pastimes may be settling in with a terrific book. In honor of March’s National Reading Month, Laurie Gauger, Ph.D., an assistant clinical professor of speech, language, and hearing sciences at the University of Florida College … Read more
Credit: Pixabay/CC0 Public Domain When we recycle electronic devices we can no longer use, we expect to make the most out of the precious natural resources that went into building them. But electronic waste is notoriously difficult to recycle because it’s hard to separate the different metals in the waste from each other. Scientists have … Read more
By wrapping a carbon nanotube with a ribbon-like polymer, Duke researchers were able to create nanotubes that conduct electricity when struck with low-energy light that our eyes cannot see. In the future, the approach could make it possible to optimize semiconductors for applications ranging from night vision to new forms of computing. Credit: Francesco Mastrocinque … Read more
Credit: AI-generated image Political anger and cynicism are rising in the United States and in many democracies worldwide, and both are associated with exposure to political attacks on social media, a new University of Michigan study shows. Americans use social media to find information and news about politics, but much of the content they see … Read more
Genus-level classification based on 16S rRNA gene sequencing data for isolates (n = 419) collected from carton (49 isolates), milk (218 isolates), mandrel sponge (mandrel; 141 isolates), and mandrel hub sponge (mandrel hub; 11 isolates) samples collected during a follow-up visit to each of 4 facilities and then stored at stored at 21°C for 24 … Read more
