Searching for past or present life on Mars is the sole driving force behind every mission we send to the red planet, from orbiters to landers to rovers. However, there remains a concern in the scientific community about Earth-based microbes hitching a ride on Mars-bound spacecraft, also called forward contamination. The concern is potentially mistaking […] Richard Dean Bird killed Christian County Deputy Gabriel Ramirez during a traffic stop; he later wounded more officers during a shootout and killed Deputy Michael Hislope Go to Source An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to investigate molecular gas in a nearby galaxy known as NGC 1387. Results of the observational campaign, published Feb. 3 in Monthly Notices of the Royal Astronomical Society, deliver important insights regarding the properties of giant molecular clouds of this galaxy. Go […] Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or a cycle of intermittent sticking and sliding between surfaces. While this framework explains many rigid-on-rigid systems such as door hinges, it […] A suspect exchanged gunfire with Colorado Springs officers, wounding one; after being shot himself, the suspect reached for an officer’s gun, prompting the other officer to fire shots Go to Source Our universe is a fascinating and mysterious place. Populated with planets, stars, meteors and other celestial bodies, it’s a never-ending source of wonder. Even with the technological revolution, we know very little about what’s going on in outer space. Are there some kinds of aliens or other life forms out there? What mysteries does […] Astronomers have captured the central region of our Milky Way in a striking new image, unveiling a complex network of filaments of cosmic gas in unprecedented detail. Obtained with the Atacama Large Millimeter/submillimeter Array (ALMA), this rich dataset—the largest ALMA image to date—will allow astronomers to probe the lives of stars in the most extreme […] Quantum technologies, devices and systems that operate leveraging quantum mechanical effects, could tackle some tasks more reliably and efficiently than any classical technology could. In recent years, some researchers have been trying to realize quantum networks to scale up the size of quantum computers, which essentially consist of several connected smaller quantum processors. Go to […] Cleopatra, the Queen of Egypt, was one of the most renowned figures of her time. She was a beautiful, intelligent, and charismatic personality that used her power and influence to shape the course of history. However, her appearance and looks are still a mystery to the world as there are no clear images or […] We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These methods are internally consistent and based on the same physics, so all observed values of the Hubble constant should agree. But those that come from […] A new study has revealed how tiny imperfections and vibrations inside a promising quantum material could be used to control an unusual quantum effect, opening new possibilities for smaller, faster, and more efficient energy-harvesting devices. Go to Source If you’ve been following exoplanet research over the last couple of years, you’ve definitely heard of K2-18b. Located 124 light years away in the constellation Leo, it’s attracted a lot of attention as it sits squarely in its red dwarf host star’s habitable zone, and measurements of the James Webb Space Telescope show its atmosphere […] In physics, the classical “Hall effect,” discovered in the late 19th century, describes how a transverse voltage is generated when an electric current is exposed to a perpendicular magnetic field. Simply put, the magnetic field causes the electrons, which are negatively charged, to drift sideways, creating a negative charge on one edge of the conducting […] Researchers at the University of Tuebingen, working with an international team, have developed an artificial intelligence that designs entirely new, sometimes unusual, experiments in quantum physics and presents them in a way that is easily understandable for researchers. This includes experimental setups that humans might never have considered. The new AI doesn’t just create a […] |
