Time crystals, a collection of particles that “tick”—or move back and forth in repeating cycles—were first theorized and then discovered about a decade ago. While scientists have yet to create commercial or industrial applications for this intriguing form of matter, these crystals hold great promise for advancing quantum computing and data storage, among other uses.
Over the years, different types of time crystals have been observed or created, with their varying properties offering a range of potential uses.
While estimates of total pregnancy losses vary considerably, about 15% of known pregnancies end in miscarriage, and many other conceptions do not survive past the very early stages of pregnancy. The primary cause for these losses is chromosomal abnormalities, like extra or absent chromosomes. Scientists have now analyzed data collected from over 140,000 IVF embryos to identify genetic differences that can increasethe risk of pregnancy loss. This work showed that there are certain genetic variants in some women that increase the risk of miscarriage. These findings, which were reported in Nature, may help scientists develop new methods to reduce the risk of pregnancy loss.
“This work provides the clearest evidence to date of the molecular pathways through which variable risk of chromosomal errors arises in humans,” said senior study author Rajiv McCoy, a computational biologist at Johns Hopkins University. “These insights deepen our understanding of the earliest stages of human development and open the door for future advances in reproductive genetics and fertility care.”

Stephen Wolfram shares surprising new ideas and results from a scientific approach to metaphysics. Discusses time, spacetime, computational irreducibility, significance of the observer, quantum mechanics and multiway systems, ruliad, laws of nature, objective reality, existence, mathematical reality.
In one-shot perceptual learning, what we see can be dramatically altered by a single past experience. Using psychophysics, fMRI, iEEG, and DNNs, the authors identify neural and computational mechanisms underlying this remarkable ability in humans.
An atomic single electron transistor, which utilizes a single atomic defect in a van der Waals material as an ultrasensitive, high-resolution potential sensor, is used to image the electrostatic potential within a moiré unit cell.
Mikhail Lukin’s team at Harvard presented a “universal” design for neutral-atom processors with robust error-correction capabilities using just 448 qubits, alongside a 3,000-qubit processor that can run for hours.
As Lukin notes: “These are really new kinds of instruments—by some measures, they’re not even computers… What’s really exciting is that these systems are now working already at a reasonable scale and we can start experimenting with them to figure out what we can do with them.”
A string of surprising advances suggests usable quantum computers could be here in a decade.
