At the bottom of the ocean, optical fibers transmit telecommunications and internet data around the world. Waveguides make that feat possible by channeling and amplifying the light—and therefore the data within—over enormous distances. Go to Source A mysterious background of extremely low-frequency gravitational waves detected by networks of pulsars may carry information about events that began more than 13 billion years ago—including the formation of some of the first supermassive black holes in the universe. Go to Source Some of Earth’s microbes likely to hitch a ride to space with human explorers could survive in the shaded nooks and crannies of the moon’s South Pole region, NASA scientists say. Go to Source When different materials transition from one phase to another, such as water coming to a boil or a magnet losing its ability to attract metals, something remarkable can happen: They begin to behave identically, following the same mathematical rules. “Physicists call this trait universality—the messy, microscopic details wash out and only a few essential features […] Before people can mine resources on the moon, asteroids or Mars, they need to answer a few key questions: What is there? How much is there? And where can it be found? A team led by SETI Institute research scientist Pablo Sobron is looking into a new way to answer these questions without having to […] Quantum computers hold great promise for applications from drug discovery to cybersecurity. Yet figuring out what would give quantum computers their edge over everyday “classical” computers is a subtle problem. A new theoretical study led by researchers at the Cavendish Laboratory shows that quantum computers are harder to make powerful than previously assumed while offering […] Some U.S. Marshals task force officers were treated for broken bones after the steep fall Go to Source Sand, powders, and other collections of visible-sized grains are found throughout daily life, from food and pharmaceuticals to soils and industrial materials. When grains of similar size are arranged regularly, they can form a strong crystal-like solid. Yet what happens inside such an ordered structure immediately before it begins to break has remained unclear. Go […] In the world of fusion energy, scientists and engineers study the fourth state of matter known as plasma in an effort to design and build a new type of power plant. Relying on the heat produced by two small atoms smashing together, a network of such facilities would help create a novel source of stable […] An Arkansas trooper performed a PIT maneuver on a suspect fleeing at 130 mph, causing the suspect vehicle to crash into a bystander vehicle and severely injure its two occupants Go to Source The driver, who had three outstanding warrants, was arrested after he fled Oklahoma City Police and almost immediately crashed and flipped his car Go to Source While county supervisors voted to end licenses allowing DHS officers to train at its gun ranges, Sheriff Kelly Martinez stated she would allow CBP officers to stay, citing economic impact concerns Go to Source Astronomers have discovered the fastest known star in our galaxy, the Milky Way, orbiting the black hole at its center. The star, named S301, was detected with the European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI) and reaches speeds of 25,000 km/s (15,500 miles per second) as it travels around the four-million-solar-mass black hole. […] As humanity gets closer to the possibility of long-term interplanetary travel, psychologists have started raising concerns about astronauts’ mental health. Researchers at Texas A&M University conducted research on sailors in an isolated environment to address these concerns using virtual reality technology and by introducing other senses to the experience, such as smell and touch.
