Supernova: A glowing DNA enzyme
Once thought to function primarily as a storage molecule for genetic information, it is now known that DNA can also catalyze chemical reactions. Although such DNA enzymes (deoxyribozymes) have not been identified in nature, they can be isolated in th.....»»
NASA telescopes start the year with a double bang
A colorful, festive image shows different types of light containing the remains of not one, but at least two exploded stars. This supernova remnant is known as 30 Doradus B (30 Dor B for short) and is part of a larger region of space where stars have.....»»
What makes urine yellow? Scientists discover the enzyme responsible
Researchers at the University of Maryland and National Institutes of Health have identified the microbial enzyme responsible for giving urine its yellow hue, according to a new study published in the journal Nature Microbiology......»»
Tissue-integrated sensitive glucose nanosenor uses inactive glucose oxidase enzyme for continuous monitoring
Monitoring glucose levels is one of the key elements in health monitoring. A research team from the University of California, Berkeley, has now developed a battery-independent fluorescent nanosensor based on single-wall carbon nanotubes and an inacti.....»»
Novel solution for Pichia pastoris enzyme production platform
The demand for industrial enzymes is continually rising, driven by the growing need to shift towards more sustainable industrial processes. Our research outlines a novel approach to enzyme production, harnessing the untapped potential of cyanobacteri.....»»
Japan"s hand-forged knives a slice of samurai metallurgy
Blacksmith Yoshihiro Yauji pulls a piece of glowing metal from the forge in a Japanese village, continuing a tradition dating back centuries to when the region was renowned for crafting swords carried by samurai......»»
Webb spots a second lensed supernova in a distant galaxy
In November 2023, the James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 appears warped by th.....»»
New possibilities for the medical use of botulinun toxin A1
PSI researchers have discovered a surprising trick that could expand the possibilities for medical use of botulinun toxin A1, better known under the name Botox, as an active agent. They have developed antibody-like proteins that speed up the enzyme's.....»»
Scientists create artificial DNA that can be transcribed by a natural enzyme
The genetic alphabet contains just four letters, referring to the four nucleotides, the biochemical building blocks that comprise all DNA. Scientists have long wondered whether it's possible to add more letters to this alphabet by creating brand-new.....»»
Research reveals a rare enzyme role change with bacterial defense system assembly
Scientists have revealed a never-before-seen phenomenon in a protein: Alone, the enzyme processes DNA and RNA but, when bound to another protein as part of a defense system, interacts with a completely different type of compound to help bacteria comm.....»»
James Webb provides a second view of an exploded star
A beautiful supernova remnant, Cassiopeia A, was recently imaged by the James Webb telescope. See how the observation compares to a previous MIRI image......»»
Using protein-glutaminase treatment to make veggie-burgers more moist
A trio of food scientists at Amano Enzyme Inc. Innovation Center, in Japan, has found that adding a protein-glutaminase treatment to plant-based meat alternatives can make the resulting product juicier. In their study, reported in PLOS ONE, Kiyota Sa.....»»
New enzyme allows CRISPR technologies to accurately target almost all human genes
A team of engineers at Duke University have developed a method to broaden the reach of CRISPR technologies. While the original CRISPR system could only target 12.5% of the human genome, the new method expands access to nearly every gene to potentiall.....»»
Ghostlike dusty galaxy reappears in James Webb Space Telescope image
It first appeared as a glowing blob from ground-based telescopes and then vanished completely in images from the Hubble Space Telescope. Now, the ghostly object has reappeared as a faint, yet distinct galaxy in an image from the James Webb Space Tele.....»»
Astronomers inspect supernova remnants with MeerKAT
Using the MeerKAT radio telescope, astronomers from the National Radio Astronomy Observatory (NRAO) in Charlottesville, Virginia, and elsewhere have investigated a batch of 36 high latitude supernova remnants. Results of the observations campaign, pu.....»»

Study yields new insights into why some people get headaches from red wine
Scientists have identified a flavonol called quercetin as the most likely culprit. Enlarge / Red wine headache (RWH) might be caused by quercetin, which inhibits an enzyme that processes acetaldehyde in the blood. (credit: Mick S.....»»
"Teenage galaxies" are unusually hot, glowing with unexpected elements
Similar to human teenagers, teenage galaxies are awkward, experience growth spurts and enjoy heavy metal—nickel, that is......»»
Gamma-ray burst charged Earth’s ionosphere from 2 billion light-years away
The brightest supernova ever detected altered the outer layers of Earth's atmosphere. Enlarge / Artist's conception of a gamma-ray burst. (credit: NASA) An astounding gamma-ray burst, dubbed GRB 221009A, continues to ama.....»»
A supernova devastated our ozone in 2022, new study reveals
In October of 2022, telescopes picked up a jet of high energy from a supernova that exploded 1.9 billion light-years away from Earth. This gamma-ray … The post A supernova devastated our ozone in 2022, new study reveals appeared first on BGR......»»
