Over 1,645 Martian days, NASA’s Perseverance Mars rover measured the fine and ultrafine Martian dust particles found clinging to samples of spacesuit materials that are carried aboard the rover, including some that are small enough to penetrate the lungs and enter the bloodstream. The findings will be published Tuesday, Oct. 27, in the Proceedings of
Before I became a mother, I thought I knew a lot about children. I had a master’s degree in child development and instructional technology and media. I had spent years studying how young children learned, processed information, and obtained mastery over a concept. When I co-created Blue’s Clues, we wanted a show built around one
Mapping microproteins in the brain might help to understand, and treat, Alzheimer’s disease.Credit: Zephyr/SPL More than 1,000 previously overlooked ‘microproteins’ have been found in samples of human brain tissue, providing researchers with the most comprehensive database yet to study these hidden molecules inside the human brain. Dozens of the tiny proteins showed altered expression in
It’s 35°C in the shade, in the middle of Europe’s June heatwave, and Alexander Janas has just emerged from the Hohle Fels cave in southwestern Germany, where the mercury reads 9 or 10°C. “It’s wonderful to be inside,” says Janas, an archaeologist at the Senckenberg Center for Human Evolution and the Paleoenvironment in Tübingen, Germany.
Specific genetic variants can be linked to a particular condition by analyzing the genomes of large groups of people with and without the disorder.Credit: Gregory Adams/Getty Researchers have identified the first evidence of genetic risk factors associated with borderline personality disorder (BPD). The analysis, published in Nature genetics July 201is the largest genome-wide association study
Researchers found a four-carbon sugar called erythrulose in a cloud of gas and dust at the center of the Milky Way (Spitzer Space Telescope image shown here).Credit: NASA, Caltech, Susan Stolovy (SSC, Caltech) Call it an extra sweet discovery. Astronomers have detected a sugar molecule swirling within a cloud of gas and dust near the
