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......»»
“Lensed” supernova could shed light on fundamental forces shaping Universe
Such objects could help refine models for Hubble Constant, dark energy, and dark matter. Enlarge / Gravitational lensing has revealed a previously unknown supernova explosion more than 4 billion light-years away. (credit: Joel Jo.....»»
Astronomers discover supernova explosion through rare "cosmic magnifying glasses"
According to Einstein's general theory of relativity, time and space are fused together in a quantity known as spacetime. The theory suggests that massive objects, like a galaxy or galaxy clusters, can cause spacetime to curve......»»
A star blew up, and scientists snapped a photo of the violent explosion
Boom.Last month astronomers spotted a star that exploded in the colossal Pinwheel galaxy some 21 million light-years away — which in cosmic terms is relatively close. The outburst of a massive star collapsing on itself, called a supernova, crea.....»»
Billion-year-old grease hints at long history of complex cells
Our ancestors once thrived on cholesterols that are now just reaction intermediates. Enlarge / All steroids past and present share the complex ringed structure but differ in terms of the atoms attached to those rings. (credit: KA.....»»
A telescope happened to be pointing at the brightest supernova yet observed
The BOAT—brightest of all time—reveals the mechanics of gamma-ray bursts. Enlarge / Artist's conception of a gamma-ray burst. (credit: NASA) Supernovae are some of the most energetic events in the Universe. And a sub.....»»
Gemini North back on sky with dazzling image of supernova in the Pinwheel Galaxy
The Gemini North telescope, one half of the International Gemini Observatory operated by NSF's NOIRLab, has returned from a seven-month hiatus literally with a bang, as it has captured the spectacular aftermath of a supernova, a massive star that exp.....»»
Researchers discover chemical evidence for pair-instability supernova from a very massive first star
The first stars illuminated the universe during the Cosmic Dawn and put an end to the cosmic "dark ages" that followed the Big Bang. However, the distribution of their mass is one of the great unsolved mysteries of the cosmos......»»
Researchers develop stepwise strategy for carbon dioxide reduction to multicarbon products
Though efficient C2+ production from CO2 electrocatalytic reduction reaction (CO2ERR) has become a promising approach to mitigate CO2 emissions and store intermittent renewable energy, it suffers from low selectivity and undesired side reactions......»»
US-Taiwan tech collab can go beyond semiconductors and into quantum and net-zero
With the US-China tech war raging on and companies like Micron caught in the crossfire, how should the government address semiconductor R&D and talent planning in response to new situational changes? Some US academics recently suggested that besides.....»»
Predicting the composition of a steel alloy
Producing energy on Earth through nuclear fusion, the type of reaction that powers the sun, has proven to be a major challenge. The extreme conditions needed for such a reaction require the walls of a nuclear fusion device to be made of a material wi.....»»
Q&A: Are liberals truly more depressed than conservatives?
Do self-identified liberals suffer from higher levels of depression than their conservative counterparts? Research suggests so, which has a small circle of commentators and academics humming with theories to explain the gap......»»
Reddit sparks outrage after a popular app developer said it wants him to pay $20 million a year for data access
Twitter has been widely criticized for trying to charge transit agencies, third-party app developers and academics for data access to its platform, a move opponents say has forced independent apps to shut down and threatened research on misinformatio.....»»
Can we really foresee break-ups? Hindsight bias in the evaluation of romantic relationships
"I knew they wouldn't last" is the reaction people often have when hearing that a couple they know has broken up......»»
The making of a Mona Lisa hologram
Holograms are often displayed in science fiction as colorful, life-sized projections. But what seems like the technology of the future is actually the technology of the present, and now it has been used to recreate the Mona Lisa......»»
AI industry and researchers sign statement warning of "extinction" risk
Dozens of AI industry leaders, academics and even some celebrities on Tuesday called for reducing the risk of global annihilation due to artificial intelligence, arguing in a brief statement that the threat of an AI extinction event should be a top g.....»»
Delete Twitter data, or pay $42K/month, company tells academics

A troubling reaction to school violence compounds the crisis
High school students who experience violence or bullying at school are more likely to bring weapons like a gun, knife, or club to school than those who have not experienced violence, according to a new study in the American Journal of Preventive Medi.....»»
Unidentified aerial phenomena observations reported by almost one fifth of academic survey respondents
