Caltech researchers have identified a novel chemical reaction that could explain the formation of the building blocks of DNA and RNA, the molecules that encode all of life’s functions. The work is an important step toward understanding how life may have emerged on Earth and potentially elsewhere in the universe, showing the straightforward and efficient […] Debris is still raining down on Earth more than 100 million years after the giant cosmic explosion that created it. A study published this week in Nature Astronomy by an international team reached this conclusion using measurements of rare isotopes within a slow-growing ferromanganese crust recovered from the depths of the Pacific Ocean. Go to […] A team of astronomers, led by Brooke Kotten of the University of Michigan, has shown that TOI-5882—a sunlike star located some 1,300 light-years away—has likely eaten one of its planets. Go to Source Saturn’s largest moon, Titan, is a unique environment in our solar system. It is the only moon (or body beyond Earth) to have a dense, nitrogen-rich atmosphere, and its methane cycle is very similar to Earth’s hydrological cycle, in which solid and liquid methane evaporate to form clouds and return to the surface as precipitation. […] Picture the Milky Way not as a silent pinwheel of stars but as something that quietly sings. Scattered through it are millions of pairs of dead stars, mostly white dwarfs, whirling around each other and stirring ripples in spacetime as they go. Individually, these ripples are far too faint to notice. Together, they blur into […] What would it take to instantly transform a material from an electrical insulator into a conductive state without ever touching it? Using ultrafast laser pulses and powerful X-rays, scientists at the National Synchrotron Light Source II (NSLS-II)—a U.S. Department of Energy (DOE) Office of Science user facility at DOE’s Brookhaven National Laboratory—developed a methodology to […] Trinity’s Prof. Stefan Sint, along with collaborators from Germany, Spain and Italy, has published the most precise determination to date of the strong coupling constant. This parameter governs the interactions between quarks and gluons, the fundamental components of nuclear matter. The new result halves the error of all previous experimental measurements combined, setting a new […] The NYPD reported four people shot or stabbed and 10 police officers attacked, with one punched in the face and another hit with a glass bottle Go to Source Video shows the suspect vehicle jumping a curve and accelerating in the direction of an officer standing back from the roadside Go to Source A video from the encounter shows the man confronting officers and arguing with them before pulling a gun from his waistband and firing shots Go to Source In the early universe, the first galaxies began to take shape roughly a million years after the Big Bang. Within these young systems, stars formed from vast reservoirs of cold gas, gradually building the structures we see in the cosmos today. Understanding this star-forming gas is key to explaining how galaxies grew, but directly tracing […] The future L.A. Metro police force received 950 applications within 24-hours of opening the portal; the agency is offering an entry-level salary of up to $132,499 per year Go to Source A team of U.S. researchers has designed a passive quantum error correction technique that enables qubits to correct their own errors. Demonstrated by Shruti Shirol and colleagues at the University of Massachusetts Amherst, the protocol transforms the inevitable dissipation of energy in qubit systems from a hindrance into an advantage, offering a promising route toward […] The ability to control the movement of negatively charged particles (i.e., electrons) is central to the functioning of all modern electronic devices. This control is typically attained using a gate, an electrode via which an applied electric field alters a material’s electrical properties. Go to Source The UK Space Agency has announced an agreement with Vast—a US commercial space company—that could send British astronaut John McFall into orbit as early as 2027. If the mission goes ahead, he would become the first person with a physical disability to live and work in space. Go to Source |
