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.....»»
The final frontier? Just a slice of Spanish sausage

Effective modification of enzyme function by computational science
Bio-manufacturing uses enzyme reactions to produce compounds that serve as materials such as pharmaceuticals, foods, fibers, and plastics. It is conducted using aqueous solvents under normal temperature and pressure conditions, as compared to convent.....»»
James Webb Space Telescope may have spotted its first supernova
The James Webb firsts keep coming, with the new space telescope having recently spotted its first supernova......»»
Satellite images + lucky boat trip give new info on glowing “milky seas”
Scientists are closer than ever to understanding the phenomenon. Enlarge / The boat trip went through an area of milky sea south of the lights of an island. (credit: Steven Miller, Leon Schommer, and Naomi McKinnon) On some mo.....»»
Researchers take first-ever cryo-EM images of nitrogenase in action
Previously, it has been impossible to capture the high-resolution images of nitrogenase, the only enzyme capable of reducing nitrogen into ammonia, during catalytic action. Now, for the first time, researchers at the University of California San Dieg.....»»
New Instrument Could Spy Signs of Alien Life in Glowing Rocks
Organisms on Earth produce a wide array of durable “biofluorescent” materials. If those on other planets do, too, the Compact Color Biofinder should be able to detect them.....»»
Study reveals insights into enzyme that combats a common greenhouse gas
An enzyme that combats the greenhouse gas nitrous oxide (N2O) may one day give scientists a potent new tool for reducing the amount of the gas in the atmosphere thanks in part to new findings published today in Nature......»»
Eerie Photo Proves the Existence of Milky Seas--A First
A night photograph taken from a sailboat near the island of Java validates a satellite image of a giant, glowing “milky sea”.....»»

Research on bacteria: Electron highway for hydrogen and carbon dioxide storage discovered
In 2013, a team of microbiologists led by Professor Volker Müller from Goethe University Frankfurt discovered an unusual enzyme in a heat-loving (thermophilic) bacterium: the hydrogen-dependent CO2 reductase HDCR. It produces formic acid (formate) f.....»»
A dying star’s last hurrah
At the end of their lives, sunlike stars metamorphose into glowing shells of gas. Enlarge / The Butterfly Nebula, located just under 4,000 light-years from Earth in the constellation Scorpius, is a striking example of a planetary nebul.....»»
Rewinding a supernova with machine learning
New work looks at using machine learning to decipher the early stages of supernovae explosions by reconstructing the light emitted during the outburst. The research was presented today at the 2022 National Astronomy Meeting by Eleonora Parrag, a Ph.D.....»»
Inside the War on Fake Consumer Reviews
When Kay Dean turned her keen detective’s eye on the reviews for a Toronto dental clinic, she quickly discovered something alarming. The reviewers behind the clinic’s glowing testimonials had also reviewed an array of obscure small busine.....»»
First cryo-EM structures of angiotensin-converting enzyme pave the way for better drugs to treat heart disease
The first full-length structures of the human angiotensin-converting enzyme (ACE) have been determined by researchers from the University of Cape Town (UCT) using cryo-electron microscopy (cryo-EM). ACE is a blood pressure-regulating protein that is.....»»
Enzyme of bacterial origin promoted the evolution of longhorned beetles
Larvae of longhorned beetles develop primarily in woody tissue, which is difficult for most organisms to digest. However, longhorned beetle larvae possess special enzymes to break down the various components of the plant cell wall. Researchers at the.....»»
The star that survived a supernova
A supernova is the catastrophic explosion of a star. Thermonuclear supernovae, in particular, signal the complete destruction of a white dwarf star, leaving nothing behind. At least that's what models and observations suggested......»»
Novel enzyme-free strategy to detect organophosphorus pesticide residues
High usage and unreasonable methods have caused excessive residues of glyphosate in agricultural products, so it's necessary to find rapid and highly selective methods for detecting glyphosate residues. Laboratory instrument–based methods or enzyme.....»»
Astronomers find evidence for most powerful pulsar in distant galaxy
Astronomers analyzing data from the VLA Sky Survey (VLASS) have discovered one of the youngest known neutron stars—the superdense remnant of a massive star that exploded as a supernova. Images from the National Science Foundation's Karl G. Jansky V.....»»
Scientists reveal function of cell death enzyme capsase-7
Researchers have unmasked a component of the cell death process that could play a vital role in a better infection-fighting strategy......»»
Cosmic "dust" from supernovae hints at how stars are born
New research detected strong polarization from a young supernova remnant. It provided independent and solid evidence that the cosmic dust in the early universe was formed in supernovae. While it's true that supernovae eject and destroy cosmic dust, i.....»»
