Community college students across the U.S. now have another opportunity to discover how their education can lead to fulfilling roles at the forefront of aerospace, science, engineering, and technology. The updated NASA Community College Aerospace Scholars (NCAS) student challenge invites students to learn about the agency and its missions, engage with NASA experts, and explore
The β-galactosidase molecule can be targeted by antibodies in experiments. But some studies have erroneously used the antibody that targets the bacterial β-galactosidase instead of the mammalian version.Credit: Laguna Design/Science Photo Library More than 50 studies on cell ageing have apparently used the wrong antibody to identify a key protein in experiments, according to a
A NASA-funded air pollution monitoring network has provided one of the most detailed long-term views yet of the role of black carbon, or soot produced by fires, diesel vehicles, and other combustion sources, in Ethiopia’s capital, Addis Ababa. The detailed measurements show how pollution changes by time of day and season, including increases associated with
Longevity isn’t only about what you eat. Social connection has been widely linked to longevity, and it can be as powerful as diet and other lifestyle factors people obsess over — and I believe a handwritten card is connection you can hold. Fortunately, Trader Joe’s has a great selection of blank greeting cards for just
Scientists using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) conducted more than 140 hours of observations of the magnetar 1E 1547-5408, shown in this Aug. 5, 2026, artist’s concept, between March and April 2025. In doing so, they may have captured empty space behaving in a way physicists have predicted for 90 years, but never directly
Credit: bpawesome/Getty Replication of experimental results is important for building credible science, but replication studies are often difficult to find. A team of researchers wants to change that. They have begun publishing replication studies on the peer review platform PubPeer, along with links to the original studies. There have been numerous attempts to replicate scientific
