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.....»»
Research reveals how a single enzyme can boost soybean oil production
As a potent source of protein and oil, soybeans are a vital global crop for food, animal feed, industrial applications, and biofuel production. Even minor improvements in soybean seed content can therefore have far-reaching implications for agricultu.....»»
Observations explore the properties of Type Ic supernova SN 2022jli
An international team of astronomers has performed multi-wavelength photometric and spectroscopic observations of a recently discovered Type Ic supernova known as SN 2022jli. Results of the observational campaign, published September 22 on the pre-pr.....»»
Hubble snaps an autumnal nebula glowing orange from young, hot stars
A new image from the Hubble Space Telescope shows a nebula in the gorgeous colors of autumn, just in time for leaf-changing season......»»
Hubble investigates the gorgeous remnants of a supernova
Scientists are using data from Hubble data of the famous Cygnus Loop supernova remnant to study how these remnants change over time......»»
Saturday Citations: Volcano vs. asteroid; NASA"s supernova time lapse; immortal chemicals
This week, we're highlighting a study involving toxic chemical contaminants, and just for fun, a second study involving other toxic chemical contaminants. But NASA made a cool time-lapse video using the good old Hubble space telescope, and a group of.....»»
Using a cutting enzyme and an RNA repair enzyme to modify RNA virus genomes
A team of microbiologists at Montana State University has developed a way to use a cutting enzyme and an RNA repair enzyme to modify the genome of an RNA virus. They describe their technique in Science Advances......»»
Bear-repelling ‘Monster Wolf’ robot gets wider deployment
Japan's Monster Wolf robot, complete with menacing roar and glowing red eyes, is being deployed more widely in a bid to keep bears in the mountains......»»
Living on the edge: Supernova bubble expands in new Hubble time-lapse movie
Though a doomed star exploded some 20,000 years ago, its tattered remnants continue racing into space at breakneck speeds—and NASA's Hubble Space Telescope has caught the action......»»
Capturing carbon dioxide with electricity: A microbial enzyme inspires electrochemistry
Humans continuously emits greenhouse gases, worsening global warming. For example, carbon dioxide (CO2) accumulates dramatically over the years and is chemically very stable. Yet, some microbes capture CO2 using highly efficient enzymes. Scientists f.....»»
Extreme weight loss: Star sheds unexpected amounts of mass just before going supernova
A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers insight into what happe.....»»
New post-translational modification of the glycolytic enzyme enolase
Proteins are subject to post-translational chemical modifications that result in functional diversity. Methylation is one such modification that is generally believed to occur on lysine and arginine residues. Recently, this modification has been show.....»»
Chemists used machine learning and molecular modeling to identify potential anticancer drugs
RUDN University chemists and colleagues from China built several machine learning models and discovered a group of potential drugs that inhibit the enzyme responsible for uncontrolled cell division. The results were published in Biomedicines......»»
Team resolves molecular switching behavior of azonium compounds for light-controlled drugs
Molecules that change shape under the influence of light can be used as switches in biomedical applications, for instance to inhibit an enzyme. An international team of researchers, including chemists at the Universities of Amsterdam and Groningen, h.....»»
New Type I supernova discovered with JWST
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed the galaxy cluster PLCK G165.7+67.0. The observational campaign resulted in the detection of a new Type I supernova. The finding is reported in a paper pub.....»»
Sometimes beneficial, sometimes damaging: The double role of the enzyme chameau
Biologists have discovered why an enzyme is important for the survival of fruit flies, even though it can shorten their lives under certain conditions......»»
Reducing the carbon footprint of methane by converting it into methanol with a new enzyme
A team led by Professor Osami Shoji at Nagoya University in Japan has developed a technology to convert methane, the principal component of natural gas, into methanol at room temperature in water. They used an enzyme that can be easily mass-produced,.....»»
Researchers uncover enzyme important in reproductive biological clock
How do you study reproductive aging, the biological clock that affects fertility, in the lab? Researchers at Howard Hughes Medical Institute's Janelia Research Campus use a surprising animal: the roundworm C. elegans......»»
Did this supernova explode twice?
All supernovae are exploding stars. But the nature of a supernova explosion varies quite a bit. One type, named Type 1a supernovae, involves a binary star where one of the pair is a white dwarf. And while supernovae of all types usually involve a sin.....»»
Webb reveals new structures within iconic supernova
NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelength.....»»
