How Columbia conservators, Nano Initiative scientists, and a music scholar used state-of-the-art technology to examine a score.
A technique can determine for the first time how frequently, and exactly where, a molecular event called “backtracking” occurs throughout the genetic material (genome) of any species, a new study shows.
Published online February 9 in Molecular Cell, the study results support the theory that backtracking represents a widespread form of gene regulation, which influences thousands of human genes, including many involved in basic life processes like cell division and development in the womb.
Led by researchers from NYU Grossman School of Medicine, the work revolves around genes, the stretches of DNA molecular “letters” arranged in a certain order (sequence) to encode the blueprints for most organisms. In both humans and bacteria, the first step in a gene’s expression, transcription, proceeds as a protein “machine” called RNA polymerase II ticks down the DNA chain, reading genetic instructions in one direction.
Cisco today announced the launch of a Webex video conferencing app designed for the Apple Vision Pro. The app is designed to provide an immersive meeting experience that fills the space around the user.
The Webex app supports Personas, allowing Vision Pro wearers to have a visual representation of themselves in video calls while wearing the headset, and it also works with spatial audio.
Microsoft is back with another Super Bowl ad, this time for its AI chatbot called Copilot. And it kind of sucks.
For most of humanity’s existence, we have observed the universe using light, but these days photons aren’t the only game in town, says Chanda Prescod-Weinstein
Physicists’ search for a theory that explains all reality in one framework appeared to have stalled. But now they are reinvigorating the hunt by exploring a wild landscape of abstract geometry.
Reliable quantum gates are the fundamental component of quantum information processing. However, achieving high-dimensional unitary transformations in a scalable and compact manner with ultrahigh fidelities remains a great challenge.
To address this issue, scientists in China showcase the use of deep diffractive neural networks (D2NNs) to construct a series of high-dimensional quantum gates, which are encoded by the spatial modes of photons. This work, published in Light: Science & Applications, offers a new paradigm for quantum gate design using deep learning.
Quantum computing holds the promise of transforming our information processing methodologies, and at its core, reliable quantum logic gates play an essential role in quantum information processing.
A LK99 researcher from Hubei, China, said that his paper might not be released before the Lunar New Year because of patent issues, announced the main findings of the paper, which detected three specific magnetic pointing superconductivity in the samples. He also described improved synthesis methods.

We present the gravitational-wave background and its properties focusing on the background from compact binary coalescences in terrestrial detectors. We also introduce the standard data analysis method used to search for this background and discuss its detectability with second and third generation networks of detectors. To illustrate, we first use simple models and then discuss more realistic models based on simulations.
