Orca, the world’s largest direct air carbon capture and storage plant, has started operating in Iceland. It is run by Swiss company Climeworks.
The keyhole imaging technique, developed by researchers at Stanford University’s Computational Imaging Lab, is so named because all that’s needed to see what’s inside a closed room is a tiny hole (such as a keyhole or a peephole) large enough to shine a laser beam through, creating a single dot of light on a wall inside.
If you’re worried about privacy, it might be time to cover up your front door’s peephole.
Hwang and colleagues lay out their platform, which could one day be integrated not only into dental implants but other technologies, such as joint replacements, as well.
More than 3 million people in America have dental implants, used to replace a tooth lost to decay, gum disease, or injury. Implants represent a leap of progress over dentures or bridges, fitting much more securely and designed to last 20 years or more.
But often implants fall short of that expectation, instead needing replacement in five to 10 years due to local inflammation or gum disease, necessitating a repeat of a costly and invasive procedure for patients.
What’s exciting about our findings is that we have identified a molecular pathway that is activated in normal acute wounds in humans, and altered in diabetic wounds in mice,” said Ghaidaa Kashgari, Ph.D., a postdoctoral researcher in the UCI School of Medicine Department of Medicine. “This finding strongly indicates clinical relevance and may improve our understanding of wound healing biology and could lead to new therapies.
A University of California, Irvine-led study identifies a new molecular pathway that promotes the healing of wounds in the skin. Titled “GRHL3 activates FSCN1 to relax cell-cell adhesions between migrating keratinocytes during wound reepithelialization,” the study was published today in JCI Insight.
The molecular pathway identified is controlled by an evolutionary conserved gene called a Grainyhead like 3 (GRHL3), which is a gene required for mammalian development. Without this gene, several abnormalities may occur, including spina bifida, defective epidermal barrier, defective eyelid closure and soft-tissue syndactyly, a condition in which children are born with fused or webbed fingers.

Many human diseases can differ between males and females in their prevalence, manifestation, severity or age of onset. Examples include Lupus, where more than 80% of patients are females; Alzheimer’s disease, where females have higher incidence and tend to suffer quicker cognitive decline; and COVID-19 infections that are frequently more severe in males.
These sex differences may have a genetic basis that is attributable to the sex chromosomes. The X chromosome—one of the two sex chromosomes—is known to play an important role in human development and disease. New research led by Penn State College of Medicine reveals for the first time that sex-biased diseases can be attributable to genes that escape X chromosome inactivation (XCI), a process that ensures that females do not overexpress genes on their X-chromosomes.
The team developed a genetic tool that can identify these XCI escape genes, and it may also help in determining whether a female will develop a sex-biased disease and if the disease will become progressively worse over time. The tool may even be useful in understanding the sex differences in immune responses to COVID-19, as the disease is thought to produce more severe symptoms and higher mortality in men than in women.

Japan says it has scrambled fighter aircraft to intercept Chinese military drones and accompanying surveillance aircraft on three consecutive days this week as its defense forces took part in a series of readiness exercises with regional allies.

High-energy laser pulses cause electrons to oscillate, giving off gamma rays that produce electrons and positrons.
Summary: A new study on aging reveals a surprising discovery about the connection between protein shape and mitochondrial health.

Every cell in the body goes through thousands of chemical reactions each day, and each reaction involves tiny protein molecules folded into precise shapes to perform their functions. Misfolded proteins underlie some of the most common and devastating diseases of aging, like Alzheimer’s and Parkinson’s. A major focus of aging research is discovering ways to maintain protein shape and prevent misfolded proteins from wreaking havoc on cellular function.

LONDON — A laboratory in Switzerland has found a way of using a laser to change and regulate the polarization, wavelength and intensity of light in “excitons” in 2D materials, creating the potential for a new generation of transistors with less energy loss and heat dissipation, opening up the potential for low-power quantum computing.
Excitons are created when an electron absorbs light and moves into a higher energy level, or “energy band” as it is called in solid quantum physics. This excited electron leaves behind an “electron hole” in its previous energy band. And because the electron has a negative charge and the hole a positive charge, the two are bound together by an electrostatic force called a Coulomb force. It’s this electron-electron hole pair that is referred to as an exciton.
