In a new study,

Two cosmonauts and a NASA astronaut undocked from the International Space Station early Wednesday and headed for landing on the steppe of Kazakhstan to close out an unexpected yearlong stay in space, the longest single flight in U.S. space history. With Soyuz MS-69/23S commander Sergey Prokopyev monitoring cockpit displays, flanked on the left by co-pilot…

Medical journals are at a “crossroads,” says a team of top editors, and new ways are needed to address threats to their integrity, according to an editorial published September 22 in JAMA. Lead author John Ioannidis, MD, of Stanford University in Stanford, CA, and editors of JAMA, the JAMA Network, and the BMJ noted that the COVID-19…

By Swiss Federal Laboratories for Materials Science and Technology (EMPA) September 26, 2023 Empa researchers and their international collaborators have successfully attached carbon nanotube electrodes to individual atomically precise nanoribbons. Credit: Empa Scientists contact single graphene nanoribbons. Quantum technology holds immense promise, yet it is riddled with complexity. Anticipated… Continue Reading News Source: https://scitechdaily.com/unveiling-nanoscale-wonders-carbon-based-quantum-technology/

Artist representation of the ancient spider. Credit: Australian Museum (AM) and University of New South Wales There have been very few fossil spiders found in Australia. Only four spider fossils have ever been found throughout the continent, making it difficult for scientists to understand their evolutionary history. A team of Australian scientists led by the……

Asteroids are huge space rocks that revolve around in their orbits in space. According to NASA, some of these ancient space rocks present a potential threat of collision with Earth while others can help discover secrets of space. While most of them are located in the main asteroid belt between the orbits of Jupiter and…

Dark powder, sand-sized particles found as lid opened on Osiris-REx space probe which collected samples from asteroid. Scientists at the United States space agency NASA found “black dust and debris” when they opened the space capsule that recently returned to Earth with the largest asteroid sample ever brought back from space. NASA said on Tuesday…

A recent review published in the journal Frontiers in Microbiology explores how the oral microbiome develops in infants, focusing on various factors such as early nutrition and environment. Since the condition of the oral microbiome has implications for the child’s well-being throughout life, scientists can use this research to develop more effective health guidelines. The……
