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.....»»
Researcher proposes paradigm shift in enzyme biochemistry
Although you may never have heard of the cytochrome P450 superfamily of enzymes, these proteins play diverse and critical roles in humans through the metabolic processing of drugs, pesticides, fatty acids, fat-soluble vitamins, and chemical carcinoge.....»»
Daily Telescope: Finally, we’ve found the core of a famous supernova
In the astronomy community, SN 1987A has somewhat legendary status. Enlarge / Webb has observed the best evidence yet for emission from a neutron star at the site of Supernova 1987A. (credit: NASA, ESA, CSA, STScI, et. al.).....»»
This famous supernova remnant is hiding a secret
Astronomers using the James Webb Space Telescope have peered into the famous SN 1987A supernova remnant and found something special inside......»»
Astronomers find first strong evidence of neutron star remnant of exploding star
An international team of astronomers including UCL's (University College London's) Professor Mike Barlow has discovered the first conclusive evidence that a neutron star exists at the center of Supernova 1987A, a star explosion observed 37 years ago......»»
Chinese astronomers find radio pulsar in a supernova remnant
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from the Nanjing University in China and elsewhere, have detected a radio pulsar in a supernova remnant known as CTB 87. The finding is reported in a paper published.....»»
Researchers discover cosmic dust storms from Type 1a supernova
Cosmic dust—like dust on Earth—comprises groupings of molecules that have condensed and stuck together in a grain. But the exact nature of dust creation in the universe has long been a mystery. Now, however, an international team of astronomers f.....»»
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.....»»
