A study led by UMass Chan Medical School researchers has demonstrated that a gene therapy to correct a mutation that causes maple syrup urine disease (MSUD) prevented newborn death, normalized growth, restored coordinated expression of the affected genes and stabilized biomarkers in a calf as well as in mice.

“Simply put, we believe the demonstrated in both animal species, especially in the cow, very well showcases the therapeutic potential for MSUD, in part because the diseased cow, without treatment, has a very similar metabolic profile as the patients,” said Dan Wang, Ph.D., assistant professor of genetic & cellular medicine.

Dr. Wang is co-principal investigator with Heather Gray-Edwards, DVM, Ph.D., assistant professor of genetic & cellular medicine; Guangping Gao, Ph.D., the Penelope Booth Rockwell Chair in Biomedical Research, director of the Horae Gene Therapy Center, director of the Li Weibo Institute for Rare Diseases Research and chair and professor of genetic & cellular medicine; and Kevin Strauss, MD, adjunct professor of pediatrics and head of therapeutic development at the Clinic for Special Children in Gordonville, Pennsylvania.

The quantum rules shaping molecular collisions are now coming into focus, offering fresh insights for chemistry and materials science. When molecules collide with surfaces, a complex exchange of energy takes place between the molecule and the atoms composing the surface. But beneath this dizzying complexity, quantum mechanics, which celebrates its 100th anniversary this year, governs the process.

Quantum interference, in particular, plays a key role. It occurs when different pathways that a molecule can take overlap, resulting in specific patterns of interaction: some pathways amplify each other, while others cancel out entirely. This “dance of waves” affects how molecules exchange energy and momentum with surfaces, and ultimately how efficiently they react.

But until now, observing in collisions with heavier molecules like methane (CH4) was nearly impossible because of the overwhelming number of pathways available for the system to take en route to the different collision outcomes. Many scientists have even wondered if all quantum effects would always “wash out” for these processes so that the simpler laws of classical physics, which apply to everyday, “macroscopic” objects, might be enough to describe them.

For the first time, researchers have used high-speed laser writing to create lines spaced just 100 nm apart on a glass substrate. The optimized printing approach could enable super-resolution 3D direct laser writing (DLW) of microlenses, photonics crystals, micro-optical devices, metamaterials and more.

DLW is an additive manufacturing technique that uses a focused laser beam to selectively solidify, or polymerize, a material with nanoscale precision. DLW typically uses multi-photon polymerization to polymerize materials in a precise, 3D manner.

“Increasing the —the minimum distance between two adjacent features—is difficult because the intense laser light can cause unwanted exposure in nearby areas during DLW,” said Qiulan Liu, a member of the research team from Zhejiang Lab and Zhejiang University in China. “However, by using a unique dual-beam optical setup and a special photoresist, we were able to overcome this challenge and achieve super-resolution DLW.”

Chiral-structural-color materials produce color through microscopic structures that interact with light rather than through pigmentation or dyes. Some beetle exoskeletons, avian feathers, butterfly wings, and marine organisms feature these structures naturally, producing iridescent or polarization-dependent colors. Over the last 10–15 years, scientists have made progress in developing artificial chiral-structural-color materials.

Recently, Chinese researchers have made a breakthrough in the field by discovering that microdomes made from common polymers exhibit tunable chiral structural colors with broad-spectrum capabilities and multiple polarization-modulated chirality. This advancement could have significant implications for applications in displays, sensors, and .

Published in PNAS, the study was led by Prof. Li Mingzhu’s team from the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences.

Many next-generation quantum devices rely on single-photon emitters based on optically active defects in solids, known as color centers. Understanding their properties is fundamental to developing novel quantum technologies.

Now, in a study published in APL Materials, a multi-institutional research team led by Osaka University has sought to clarify the origin of the extremely bright color centers at the interface between (SiO2) and silicon carbide (SiC).

Previous research has demonstrated a range of factors that can play a role in the formation of these interface color centers, including the effect of annealing after oxidation. However, the energy level structure (i.e., the electronic transitions taking place) responsible for luminescence, a crucial factor for understanding the origin of color centers, was completely unknown.

Researchers at Tohoku University, the University of Manchester, and Osaka University have made a breakthrough that has the potential to ignite the development of next-gen chiral information technology.

The findings are described in a study published in Proceedings of the National Academy of Sciences.

Chirality is a property of materials where their mirror image is not identical to the original—just like our left and right hands. This unique characteristic creates two distinct states, which researchers believe could one day be used to store , much like the “0” and “1” states in conventional computing.

When you look at your surrounding environment, it might seem like you’re living on a flat plane. After all, this is why you can navigate a new city using a map: a flat piece of paper that represents all the places around you.

This is likely why some people in the past believed the Earth to be flat. But most people now know that is far from the truth.

You live on the surface of a giant sphere, like a beach ball the size of the Earth with a few bumps added. The surface of the sphere and the plane are two possible 2D spaces, meaning you can walk in two directions: north and south or east and west.

“The Ouroboros Code” explores the intersection of science and spirituality through the lens of digital alchemy and self-simulation. Authored by Antonin Tuynman, the book presents a philosophical framework called “The Transcendental Metaphysics of Pancomputational Panpsychism” exploring how consciousness may be the fundamental ground of existence and the universe a self-modifying code. Tuynman investigates topics like the nature of intelligence, the limits of computation, and the possibility of artificial general intelligence. The book draws on concepts from physics, information theory, mathematics, and various spiritual traditions, aiming to bridge the gap between objective and subjective realities. It builds upon the author’s previous works and incorporates insights from various scientists and thinkers. Ultimately, the book seeks to understand how the universe, through a recursive process, generates and experiences itself. *Available as a Kindle eBook, paperback, and Audible audiobook: https://www.amazon.com/Ouroboros-Code?tag=lifeboatfound-20… #SelfSimulation #Pancomputationalism #DigitalPhysics #ComputationalPhysics
