Welcome back to the Summary! Here are this week’s studies that detected a blast from the past, opened a portal between realms, opened it, and rose from the ashes. First, scientists have detected a mysterious radio signal from the primordial universe that could illuminate cosmic evolution (not aliens…sorry). Then: a quantum diamond in the rough, the decline of a fine bovine line, and a second-generation planet. As always, for more of my work, check out my book First Contact: The Story of Our Obsession with Aliens or subscribe to my personal newsletter The BeX Files. A long time ago, in a galaxy far, far away, Caleb, Manisha et al. “A rapid radio explosion at redshift 2, three billion years after the Big Bang”. Science. Scientists have discovered the most distant fast radio burst (FRB), a type of mysterious radio flare from space. This explosion erupted when the universe was just three billion years old and sent radio waves across 10 billion light years before reaching Earth on March 4, 2024. The distant signal, known as FRB 20240304B, comes from an ancient galaxy beyond “redshift 2,” meaning it originated more than twice as far away as the next-most distant known FRB. Redshift, represented by the variable “z,” measures how the wavelengths of light lengthen as they travel through space, a phenomenon that shifts them toward the red end of the spectrum. Generally speaking, the more distant the object is from Earth, the greater the redshift. “Approximately one hundred FRBs have identified host galaxies at measured redshifts, with the vast majority at redshifts z ≲ 0.5,” said researchers led by Manisha Caleb of the Sydney Institute of Astronomy. “Only a small number of FRB host galaxies have been identified at z ≳ 1. This observation bias is driven by the sensitivity limit of radio observations that are able to detect FRBs and locate their coordinates.” Caleb and his colleagues were able to capture the remote flash using the MeerKAT radio telescope in South Africa. Follow-up observations with the James Webb Space Telescope identified “a lumpy, low-mass star-forming galaxy” with a redshift of 2.148 as the host of the explosion. FRBs produce incredibly energetic radio pulses, but the exact mechanisms that generate them remain unknown. Given the various characteristics of these bursts (for example, some are repeated and others are unique), they can come from many different sources. In the case of FRB 20240304B, the team speculated that the explosion is a magnetar, the highly magnetized remains of a massive star that went supernova. “The low stellar mass, active star formation, and low metallicity of the host galaxy are consistent with a magnetar origin of the FRB,” the researchers concluded. This important detection of such a distant and ancient FRB opens the possibility of finding more explosions at high redshifts. In addition to pushing the limits of observation, future discoveries could allow scientists to extract clues about the evolution of the universe that are imprinted in these signals during their vast travels. So come the past bursts! In other news… Putting a quantum spin on things Nayak, Anshuman et al. “Spin force from a vacant nitrogen assembly drives a 100 mg levitated resonator.” Science advances. It is time to shrink from the larger cosmic scale to the small quantum realm. In a new study, scientists report that they successfully moved a centimeter-scale diamond with a force known as quantum spin, making it by far the largest object ever manipulated using a quantum effect. It represents a breakthrough, as the diamond is the first object large enough to be subject to gravity and able to move in this way, further closing the gap between the crazy quantum realm and everyday physics. A graphic representation of the observed movements. a) When the laser is off, the diamond slab has a small magnetic moment (blue arrow) induced by the latent spin state within the nitrogen vacancy centers of the diamond. b) When the green laser is on, the spin state becomes polarized, causing the magnetic moment to fluctuate weakly, pushing the diamond into the magnetic field (red arrows). Image: Nayak et al., 2026 In the new work, the scientists worked with a nitrogen vacancy (NV) diamond that contained electrons with “spin,” a form of angular momentum on the quantum scale. They then shot a laser at the diamond, as science usually demands, which stimulated the electrons to spin in a certain state that eerily moved the diamond. “Observing this spin force experimentally for anything larger than atomic scales has proven challenging,” said researchers led by Anshuman Nayak of the Okinawa Institute of Science and Technology. “We have demonstrated the motor driving of a massive mechanical oscillator diamagnetically levitated by the force of NV spins in a gradient magnetic field.” Congratulations, humanity: we just got our quantum motion driving license. Proceed responsibly. A new yak has just fallen Oppenheimer, Jonas and Gillardet, Alexandre et al. “Ancient genomes reveal an extinct bovine species from mid-latitude Asia.” Current biology. Domestic cows are overwhelmingly the most common bovine species on Earth today, but this family of swole ungulates once contained a diversity of wild lineages that included aurochs, steppe bison, and oxen. Now, scientists have discovered the remains of a different bovine species, called “yak Yak The youngest bones of this mysterious animal date back to about 27,200 years ago, so it must have become extinct some time later. “Yak “Yak relatives. This has been Yak News. The Birth and Death of a Phoenix PlanetWilliams, Jamie T. et al. “Discovery of a second-generation planet candidate accreting into a white dwarf.” Nature Geoscience. Planets are frequently destroyed by the explosive death of their stars, but they can also be born from those same stellar ashes. Scientists have now directly observed the first evidence of one of these so-called “second generation” planets that formed around a type of dead star called a white dwarf. Located about 270 light years from Earth, the white dwarf, known as HS 0209+0832, was once a Sun-like star. About five million years ago, it shed its red giant shell and collapsed to its current shell state. Concept art of the second generation planet. Image: Dr Snehalata Sahu / University of Warwick Since its transition to the afterlife, a new planet has fused those expelled embers, although this world is destined for an early grave. Scientists detected telltale signs of second-generation elements (including zinc, copper and niobium) in the white dwarf’s spectrum, which are distinct from first-generation planetary ingredients such as silicon and iron that make up Earth. The discovery exposes a dead star feeding on its posthumous offspring born from its own ghostly gas. “Here we report the discovery of a white dwarf accreting material unlike any object in the Solar System,” said researchers led by Jamie Williams of the University of Warwick. “The discovery of this second-generation planet that is chemically distinct from the first-generation material demonstrates that nearby planets can form around white dwarfs…Establishing a sizable sample of such systems will open a window into the formation of second-generation planets.” Some stars are so prolific that not even death will stop them from creating new worlds and then eating them. I respect. Thanks for reading! See you next week.
