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.....»»
Artificial intelligence finds the first stars were not alone
By using machine learning and state-of-the-art supernova nucleosynthesis, a team of researchers have found the majority of observed second-generation stars in the universe were enriched by multiple supernovae. Their findings are reported in The Astro.....»»

Webb captures rarely seen prelude to a supernova
A Wolf-Rayet star is a rare prelude to the famous final act of a massive star: the supernova. As one of its first observations in 2022, the NASA/ESA/CSA James Webb Space Telescope captured the Wolf-Rayet star WR 124 in unprecedented detail. A distinc.....»»
Hubble captures a messy irregular galaxy which hosted a supernova
This week's image from the Hubble Space Telescope shows a spiral galaxy called NGC 5486, shot through with wisps of pink where new stars are being born......»»
Enzyme ATE1 plays role in cellular stress response, opening door to new therapeutic targets
A new paper in Nature Communications illuminates how a previously poorly understood enzyme works in the cell. Many diseases are tied to chronic cellular stress, and UMBC's Aaron T. Smith and colleagues discovered that this enzyme plays an important r.....»»
Magnetic recoverable enzyme formulation removes mycotoxin from fruit-derived products
A research team led by Prof. Li Boqiang from the Institute of Botany of the Chinese Academy of Sciences has developed an immobilized enzyme preparation with high efficiency, stability, safety and easy separation, which can degrade patulin in contamin.....»»
Newly discovered enzyme that turns air into electricity, providing a new clean source of energy
Australian scientists have discovered an enzyme that converts air into energy. The finding, published today in the journal Nature, reveals that this enzyme uses the low amounts of the hydrogen in the atmosphere to create an electrical current. This f.....»»
This rare photo shows the oldest known supernova from the year 185 AD
In the year 185 AD, Chinese astronomers noted the appearance of a “guest star” in the night sky. This guest star remained visible in the … The post This rare photo shows the oldest known supernova from the year 185 AD appeared first on BGR......»»
James Webb captures an extremely distant triple-lensed supernova
Webb imaged a huge galaxy cluster located 3.2 billion light-years away, which is acting like a magnifying glass and showing a far-off supernova in triplicate......»»
Telescope captures the remnants of a supernova first seen 2,000 years ago
Astronomers recently captured a remnant called RCW 86, which is the result of a supernova which was observed by Chinese astronomers in the year 185 C.E......»»
Feast your eyes on this image of remnant from earliest recorded supernova
Dark Energy Camera captures rare view of RCW 86, remnant of supernova recorded in 185 CE. Enlarge / The tattered shell of the first recorded supernova (Sn185) was captured by the Dark Energy Camera. This image covers an impressiv.....»»
Resurrected supernova provides missing link between two types
Astronomers have discovered a supernova exhibiting unprecedented rebrightening at millimeter wavelengths, providing an intermediate case between two types of supernovae: those of solitary stars and those in close-binary systems......»»
Previously unknown mechanism in precision RNA cleaving by Dicer enzyme revealed
Researchers at the Center for RNA Research, Institute for Basic Science (IBS), in Seoul, have published a study with critical new insights into the structure and function of the Dicer enzyme. Dicer is an enzyme required for the biogenesis of miRNAs.....»»
Researchers develop small molecule to stimulate natural killer cells against neuroblastoma
An MUSC Hollings Cancer Center research team has created what team members believe to be among the first small molecules designed to stimulate immune cells to fight cancer. More importantly, these compounds inhibit a specific enzyme that hasn't been.....»»
New technique probes chemistry of enzyme implicated in Alzheimer"s and cancer
If serine racemase is the magician that for decades disguised its trick—inverting an amino acid to assist learning and memory but also levitate risks of Alzheimer's and stroke—chemists just snuck a high-res camera behind the curtain......»»
Humanity is the reimagined 3D Lemmings we didn’t know we needed
Trippy trailer, fun demo have us excited for Tetris Effect publisher's May game. Enlarge / You are a glowing dog. The humans lack all purpose. You must direct them to their final ascension. That's the game. (credit: Enhance).....»»
Researchers uncover how photosynthetic organisms regulate and synthesize ATP
ATP, the compound essential for the functioning of photosynthetic organisms such as plants, algae, and cyanobacteria, is produced by an enzyme called "chloroplast ATP synthase" (CFoCF1). To control ATP production under varying light conditions, the e.....»»
Researchers activate an enzyme with light, revealing its role in metabolism
Takeaki Ozawa and his team from the University of Tokyo have revealed the metabolic reactions that take place after activating an enzyme called Akt2. In doing so, they reveal the inner workings of insulin-regulated metabolism. The findings lead the w.....»»
Gene cluster reshuffling drives natural sunscreen evolution in lichens
A new study reveals that the evolution of sunscreen pigments in lichen-forming fungi has been governed by the reshuffling of existing enzyme genes and novel accessory genes into new gene clusters......»»
Astronomers identify 20 ultraviolet-emitting supernova remnants in the Andromeda Galaxy
