Researchers at the Hong Kong University of Science and Technology (HKUST) have developed a new integration technique for efficient integration of III-V compound semiconductor devices and silicon, paving the way for photonic integration at low cost, large volume, and high speed and throughput that could revolutionize data communications. Go to Source The King County Sheriff’s Office helicopter monitored two suspects who went on a carjacking spree, giving the Kent Police Department probable cause to initiate a pursuit Go to Source NASA is seeking applicants to participate in its next simulated one-year Mars surface mission to help inform the agency’s plans for human exploration of the Red Planet. The second of three planned ground-based missions called CHAPEA (Crew Health and Performance Exploration Analog) is scheduled to kick off in spring 2025. Go to Source […] Fast radio bursts (FRBs) are strange events. They can last only milliseconds, but during that time can outshine a galaxy. Some FRBs are repeaters, meaning that they can occur more than once from the same location, while others seem to occur just once. We still aren’t entirely sure what causes them, or even if the […] For a long time, our understanding of the universe’s first galaxies leaned heavily on theory. The light from that age only reached us after traveling for billions of years, and on the way, it was obscured and stretched into the infrared. Clues about the first galaxies are hidden in that messy light. Now that we […] The future of space exploration includes some rather ambitious plans to send missions farther from Earth than ever before. Beyond the current proposals for building infrastructure in cis-lunar space and sending regular crewed missions to the moon and Mars, there are also plans to send robotic missions to the outer solar system, to the focal […] The chatter from the radio traffic was nonstop as dispatchers and commanders managed ambulances, medical resources and officers for traffic and crowd control Go to Source NASA’s OSIRIS-REx spacecraft delivered 4.29 ounces (121.6 grams) of material from asteroid Bennu when it returned to Earth on Sep. 24, 2023; the largest asteroid sample ever collected in space and over twice the mission’s requirement. Go to Source Nuclear power is considered one of the ways to reduce dependence on fossil fuels, but how to deal with nuclear waste products is among the issues surrounding it. Radioactive waste products can be turned into more stable elements, but this process is not yet viable at scale. Go to Source “So then I hear, ‘Get him!’ and I look to my left, and it wasn’t but a second and a half, maybe two seconds,” Trey Filter said. “And somebody was running past me, and they’re yelling, ‘Get him!’ So I jumped” Go to Source Sheridan Police Sgt. Nevada Krinkee died at a hospital after being shot when he tried to serve the man with a trespass warning Go to Source According to a recent study from the University of Helsinki, published in the journal Physical Review Letters, a vortex of a superfluid that has been quantized four times has three ways of dividing, depending on the temperature. Go to Source A dipole magnetic field, created by a ring current, is the most fundamental type of magnetic field that is found both in laboratories and in space. Planetary magnetospheres, such as Jupiter’s, effectively confine plasma. Go to Source The inside of underwater pipes and enclosed nuclear containers were inaccessible—until recently. Acoustics researchers in Penn State’s College of Engineering have developed a way to convey energy and transmit communications through metal walls using ultrasound. Go to Source The Space Climate Research Group at the University of Oulu, Finland has been studying the effects of energetic particle precipitation from space, more commonly known as the aurora borealis or Northern Lights, on winter weather variations for quite some time. The aurora borealis is not only a beautiful light phenomenon, but also involves chemical changes […] |
