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.....»»
Betelgeuse before, during and after the Great Dimming
When a prominent star in the night sky suddenly dims, it generates a lot of interest. That's what happened with the red supergiant star Betelgeuse between November 2019 and May 2020. Betelgeuse will eventually explode as a supernova. Was the dimming.....»»
Enzyme for biocatalysis uses solvent as a substrate
A large number of applications in the chemical industry rely on the molecules NADH or NADPH as fuel. A team led by Professor Dirk Tischler, head of the Microbial Biotechnology working group at Ruhr University Bochum, used a biocatalyst to study their.....»»

Teaching nature to break man-made chemical bonds
For the first time, scientists have engineered an enzyme that can break stubborn man-made bonds between silicon and carbon that exist in widely-used chemicals known as siloxanes, or silicones. The discovery is a first step toward rendering the chemic.....»»
Hubble captures an exceptionally luminous supernova site
This week's image from the Hubble Space Telescope shows the aftermath of an epic explosion in space, caused by the death of a massive star......»»
Image: Hubble views a galactic supernova site
This image features a relatively small galaxy known as UGC 5189A, which is located about 150 million light-years away in the constellation Leo. This galaxy was observed by the NASA/ESA Hubble Space Telescope to study a supernova explosion in 2010 kno.....»»
Glowing COVID-19 diagnostic test prototype produces results in one minute
Cold, flu and COVID-19 season brings that now-familiar ritual: swab, wait, look at the result. But what if, instead of taking 15 minutes or more, a test could quickly determine whether you have COVID-19 with a glowing chemical? Now, in ACS Central Sc.....»»

Researcher: Healthy cities aren"t a question of boring or exciting buildings but about creating better public space
The US developers of a 300-ft glowing orb, set to be built in the middle of Stratford, east London, and accommodate upwards of 21,500 concert goers, have withdrawn their planning application......»»
Researchers report successful synthesis of specific chiral molecules using rearrangements of simple hydrocarbons
In nature, organic molecules are either left- or right-handed, but synthesizing molecules with a specific "handedness" in a lab is hard to do. Make a drug or enzyme with the wrong "handedness," and it just won't work. Now chemists at the University o.....»»
Daily Telescope: A crab found in the night sky rather than the world’s oceans
Oh, to have seen this supernova back in the day. Enlarge / The Crab Nebula in all its glory. (credit: Paul Macklin) Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough lig.....»»

A stunning new image of a supernova remnant combines data from four different telescopes to show a colorful, detailed picture of a busy region of space......»»
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.....»»

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
