Bill Nelson, 78, the former Florida senator and spaceflight veteran, became the NASA Administrator on May 3, 2021. One month later, Bill Nelson has directed NASA to study UFOS (or UAPs). Notably, the push comes as a much-anticipated UAP report is due to Congress. In 1986, Nelson flew on the 24th flight of […] Microgravity is known to alter the muscles, bones, the immune system and cognition, but little is known about its specific impact on the brain. To discover how brain cells respond to microgravity, Scripps Research scientists, in collaboration with the New York Stem Cell Foundation, sent tiny clumps of stem-cell derived brain cells called “organoids” to […] In a span of about 20 hours, SpaceX could manage three rocket launches and one landing of a Dragon spacecraft. Go to Source A group of Brazilian researchers has presented an innovative proposal to resolve a decades-old debate among theoretical physicists: How many fundamental constants are needed to describe the observable universe? Here, the term “fundamental constants” refers to the basic standards needed to measure everything. Go to Source Researchers have developed a new hyperspectral Raman imaging lidar system that can remotely detect and identify various types of plastics. This technology could help address the critical issue of plastic pollution in the ocean by providing better tools for monitoring and analysis. Go to Source Leveraging the principles of quantum mechanics, quantum computers can perform calculations at lightning-fast speeds, enabling them to solve complex problems faster than conventional computers. In quantum technology applications such as quantum computing, light plays a central role in encoding and transmitting information. Go to Source Submarines are emerging as a unique research platform to study human adaption to extreme environments—from ocean depths to outer space. Go to Source The winter solstice is Saturday, bringing the shortest day and longest night of the year to the Northern Hemisphere—ideal conditions for holiday lights and warm blankets. Go to Source Pile up blocks until the tower collapses. But why does the tower always end up collapsing? Is it possible that it can be built ad infinitum? A study published in the International Journal of Solids and Structures explores the fascinating and complex dynamics of the stacking of blocks subjected to hazards. Carried out by Vincent […] Since antiquity, wreaths have symbolized the cycle of life, death, and rebirth. It is fitting then that one of the best places for astronomers to learn more about the stellar lifecycle resembles a giant holiday wreath itself. Go to Source A research team has proposed a new method to reconstruct the “family tree” of black holes. Published in The Astrophysical Journal, this research offers a way to infer the properties of the black hole progenitors of these mergers, one of the most brutal events that can be observed in the universe. Go to Source […] X-rays are radiated by matter hotter than one million Kelvin, and high-resolution X-ray spectroscopy can tell us about the composition of the matter and how fast and in what direction it is moving. Quantum calorimeters are opening this new window on the universe. First promised four decades ago, the quantum-calorimeter era of X-ray astronomy has […] String theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a “provable” phenomenon. But a team of physicists has now taken a significant step forward in validating string theory by using an innovative mathematical method that points to its “inevitability.” Go to Source […] Madera County Sheriff’s Office deputies were pursuing the man after he allegedly stole a vehicle and hit multiple other cars; K-9 Obie was shot with numerous pellets in the pursuit Go to Source A NASA-funded commercial space station, Starlab, recently completed four key developmental milestones, marking substantial progress in the station’s design and operational readiness.
