Academics recreate supernova reaction in a lab
Researchers in Surrey's Nuclear Physics Group have collaborated with TRIUMF National Laboratory (Canada) to achieve the first direct measurement of a supernova reaction in a laboratory using an accelerated beam of radioactive nuclei......»»
Hubble detects celestial "string of pearls" star clusters in galaxy collisions
When spectacular cosmic events such as galaxy collisions occur, it sets off a reaction to form new stars, and possibly new planets that otherwise would not have formed. The gravitational pull that forces the collisions between these galaxies creates.....»»
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.....»»
How long did Neanderthals and modern humans co-exist in Europe? Evidence suggests it may have been at least 10,000 years
The idea that two different human species, Homo sapiens (us) and Neanderthals, co-existed in western Eurasia 50–40,000 years ago has long captured the imagination of academics and the public alike......»»
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.....»»

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.....»»
A cheap substitute for expensive metal in an industrially common chemical reaction
The chemical industry commonly uses rare, expensive metals to produce pharmaceuticals and other essential substances. Replacing these metals whenever possible with more abundant, cheaper substitutes would benefit environmental sustainability, lower c.....»»
Research reveals gas-phase migration route for formation of strong metal-support interaction state
Strong metal-support interaction (SMSI) is one of the most important concepts in heterogeneous catalysis. Triggered by pretreatment or reaction processes, the supported metal nanoparticles may be partially or completely encapsulated by support-derive.....»»
3D scanning: Researchers recreate a sacred South African site in a way that captures its spirit
These days, if you want to visit remarkable archaeological sites such as Great Zimbabwe or Petra in Jordan you don't even need to leave your house......»»
Daily Telescope: A beautiful supernova remnant from an uncertain age
Sometimes astronomy can be a bit imprecise. Enlarge / Behold, the Jellyfish Nebula. (credit: Hamza Syed) Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little.....»»
Study reveals a reaction at the heart of many renewable energy technologies
A key chemical reaction—in which the movement of protons between the surface of an electrode and an electrolyte drives an electric current—is a critical step in many energy technologies, including fuel cells and the electrolyzers used to produce.....»»
Researchers realize ethylene methoxycarbonylation reaction over single-atom catalyst
Ethylene methoxycarbonylation reaction is the key process in the alpha-route to produce methyl methacrylate industrially. This approach has the advantages of using widely available raw materials, having high atomic efficiency as well as high selectiv.....»»
Methane activation by [LnO]+: The 4f orbital matters
As the "holy grail" in the field of chemistry, the catalytic activation of methane has been a topic of great interest in the field of heterogeneous catalysis. Gas-phase experiments provide an ideal platform for exploring catalytic reaction mechanisms.....»»
Transmitting a domino reaction using redox chemistry achieved for the first time
Domino reactions occur when the transformation of one chemical group stimulates the reaction of another attached group, or another molecule, leading to a rapid knock-on effect through the system like a row of falling dominoes. Researchers at Hokkaido.....»»
Engineering stable and efficient nanosheet catalysts with Turing structures for hydrogen production
Hydrogen energy has emerged as a promising alternative to fossil fuels, offering a clean and sustainable energy source. However, the development of low-cost and efficient catalysts for hydrogen evolution reaction remains a challenge......»»
