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.....»»
Hubble spotlights a supernova
This NASA/ESA Hubble Space Telescope image features the galaxy LEDA 857074, located in the constellation Eridanus. LEDA 857074 is a barred spiral galaxy, with partially broken spiral arms. The image also captured a supernova, named SN 2022ADQZ, shini.....»»
Predicting metabolic potential in bacteria from limited genome data
How bacteria eat food, and what kinds of products they can make from that food, is dictated by the metabolic network of enzyme patterns encoded in their genomes. Using computational methods to learn these patterns across a large number of known bacte.....»»
Image: Doomed star Eta Carinae
Eta Carinae may be about to explode. But no one knows when—it may be next year, it may be 1 million years from now. Eta Carinae's mass—about 100 times greater than our sun—makes it an excellent candidate for a full blown supernova......»»
Breakthrough in plant disease: New enzyme could lead to anti-bacterial pesticides
Plant diseases pose significant challenges to agricultural productivity, presenting formidable hurdles that require urgent attention. Left unchecked, these diseases can spread rapidly, inflicting widespread damage on crops and leading to reduced yiel.....»»
Nature-inspired novel catalyst paves the way for efficient hydrocarbon decomposition
A research team affiliated with UNIST has developed a novel catalyst that mimics the ability of a natural enzyme to break down harmful hydrocarbons, paving the way for a more environmentally friendly and energy-efficient approach to reducing pollutio.....»»
Researchers advance understanding of a key celiac enzyme
Celiac disease affects around one in a hundred people worldwide, and those that have the autoimmune disorder have no choice but to stick to a gluten-free diet forever—at the moment, doctors have no other way to treat the illness......»»
Discovery of a tRNA modification enzyme that also acts on nucleosides
The genetic information on DNA is transcribed into messenger RNA (mRNA) and translated to the amino acid sequence by transfer RNA (tRNA) on the ribosome. Modified nucleosides within RNA are involved in maintaining and regulating the protein synthesis.....»»
Scientists replicate enzyme that captures carbon
Scientists from King's College London have recreated the active site of Acetyl-CoA Synthase, an enzyme involved in capturing carbon from the atmosphere. The research, carried out in collaboration with Imperial College London, advances our understandi.....»»
Enzyme-powered "snot bots" help deliver drugs in sticky situations
Snot might not be the first place you'd expect nanobots to be swimming around. But this slimy secretion exists in more places than just your nose and piles of dirty tissues—it also lines and helps protect the lungs, stomach, intestines and eyes. An.....»»
Webb unveils stunning ejecta and CO structures in Cassiopeia A"s young supernova
The SETI Institute announced the latest findings from the James Webb Space Telescope (JWST) of the supernova remnant, Cassiopeia A (Cas A). These observations of the youngest known core collapse supernova in the Milky Way provide insights into the co.....»»
Webb Space Telescope"s latest cosmic shot shows pair of intertwined galaxies glowing in infrared
The Webb Space Telescope has captured a pair of intertwined galaxies glowing in the infrared......»»
Hubble measures the distance to a supernova
Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it's a difficult one to complete......»»
Research team models connection between enzyme activity and yields for the first time
A team from the University of Illinois has developed a modeling framework connecting enzyme activity related to photosynthesis to yield. This is the first time a model has tied the dynamic photosynthetic pathways directly to crop growth......»»
Phage-derived enzyme targets E. faecalis biofilms to mitigate acute graft-versus-host disease
Allogenic hematopoietic cell transplantation (allo-HCT) involves transferring healthy donor stem cells to recipients with conditions such as blood cancer, bone marrow failure, or certain genetic blood disorders. Acute graft-versus-host disease (aGVHD.....»»
Newly identified enzyme helps pathogenic fungus build protective cell wall
Researchers at the School of Medicine have identified a novel enzyme involved in building the cell wall of Cryptococcus neoformans, a fungus that causes lung infections and potentially deadly cases of meningitis, primarily in people with AIDS. About.....»»
Elusive temporary star described in historical documents recreated using new computer model
A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary "guest star," now labeled supernova (SN) 1181, which was recorded in historical documents.....»»
If Betelgeuse Explodes, Just How Bright Will It Get?
This supergiant star is in our celestial neighborhood, and it’s threatening to go supernova. What would that look like from down here?.....»»
Researchers capture never-before-seen view of gene transcription
Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA. Within a few hundred milliseconds, the DNA double helix unwinds to form a node known as the transcription bubble, so that one.....»»
Study shows transgenic expression of rubisco factors increases photosynthesis and chilling tolerance in maize
Maize is one of the world's most widely grown crops and is essential to global food security. But like other plants, its growth and productivity can be limited by the slow activity of Rubisco, the enzyme responsible for carbon assimilation during pho.....»»
