Complex organosulfur molecules on comet 67P: Evidence from Rosetta orbiter and the lab
The Rosetta orbiter spectrometer for ion and neutral analysis (ROSINA) instrument orbited comet 67P to revolutionize our understanding of cometary material composition. A key finding of the satellite was to explore the composition of comet 67P/Churyu.....»»
Proposed sex education guidance in England goes against evidence and may well lead to harm
The UK government has released new plans for relationships, sex and health education (RSHE) in primary and secondary schools in England. This would see age parameters introduced for key issues in sex education, with no education on sex at all for chi.....»»
Tracing the history of perturbative expansion in quantum field theory
Perturbative expansion is a valuable mathematical technique which is widely used to break down descriptions of complex quantum systems into simpler, more manageable parts. Perhaps most importantly, it has enabled the development of quantum field theo.....»»
Data from MAXI J1820+070 shows Einstein was right about how matter plunges into a black hole
A team of astrophysicists from the University of Oxford, Newcastle University and the Institute of Astronomy, all in the U.K., working with a colleague from the University of Virginia, in the U.S., has found evidence showing that Albert Einstein was.....»»
Robert F. Kennedy Jr. sues Meta, citing chatbot’s reply as evidence of shadowban
Presidential candidate believes Meta’s chatbot can reliably reveal shadowbans. Enlarge / Screenshot from the documentary Who Is Bobby Kennedy? (credit: whoisbobbykennedy.com) In a lawsuit that seems determined to ignor.....»»
Scientists demonstrate the survival of quantum coherence in a chemical reaction involving ultracold molecules
If you zoom in on a chemical reaction to the quantum level, you'll notice that particles behave like waves that can ripple and collide. Scientists have long sought to understand quantum coherence, the ability of particles to maintain phase relationsh.....»»
A new space mission may help physicists answer "hairy" questions about black holes
Physicists consider black holes one of the most mysterious objects that exist. Ironically, they're also considered one of the simplest. For years, physicists like me have been looking to prove that black holes are more complex than they seem. And a n.....»»
Researchers shed light on how key ingredient for life may form in space
A team led by University of Maryland chemists discovered a new way to create carbenes, a class of highly reactive yet notoriously short-lived and unstable molecules. Involved in many high-energy chemical reactions such as the creation of carbohydrate.....»»
Scientists use generative AI to answer complex questions in physics
When water freezes, it transitions from a liquid phase to a solid phase, resulting in a drastic change in properties like density and volume. Phase transitions in water are so common most of us probably don't even think about them, but phase transiti.....»»
Webb detects most distant black hole merger to date
An international team of astronomers have used the NASA/ESA/CSA James Webb Space Telescope to find evidence for an ongoing merger of two galaxies and their massive black holes when the universe was only 740 million years old. This marks the most dist.....»»
Discovery may explain why Egyptian pyramids were built along long-lost Ahramat branch of the Nile
Some 31 pyramids in Egypt, including the Giza pyramid complex, may originally have been built along a 64-km-long branch of the river Nile which has long since been buried beneath farmland and desert. The findings, reported in a paper in Communication.....»»
Study shows regenerating worms have genetic control over their algal partners
Many organisms are far more complex than just a single species. Humans, for example, are full of a variety of microbes. Some creatures have even more special connections, though......»»
Underground "anomaly" found near iconic Giza pyramid complex
A multi-institutional team of archaeological researchers from Japan and Egypt has discovered what they describe as an underground "anomaly" near the iconic Giza pyramid complex. In their study, published in the journal Archaeological Prospection, the.....»»
Fossil found in Germany shows starfish relative engaged in clonal fragmentation 150 million years ago
A team of paleontologists from Germany and Austria reports that a brittle star fossil found in Germany shows evidence of clonal fragmentation 150 million years ago. Their paper is published in the journal Proceedings of the Royal Society B: Biologica.....»»
New research employs shutter speed analogies to validate 55-year-old theory about chemical reaction rates
Chemical reactions are commonly depicted as transitions from reactants to products. However, such reactions involve many molecules, and the individual molecules themselves undergo frequently-occurring structural changes as they transform from the rea.....»»
FAA initiates environmental impact study for SpaceX Starship launches from Kennedy Space Center
SpaceX's plans to build a Starship launch complex at Kennedy Space Center are moving closer to reality even as it potentially takes over a launch site from neighboring Cape Canaveral Space Force Station......»»
Discovery of biomarkers in space—conditions on Saturn"s moon Enceladus simulated in the laboratory
In 2018, very large organic molecules were discovered in ice particles on Saturn's moon Enceladus. It is still unclear whether they indicate the existence of life or were created in some other way. A recent study could help to answer this question. I.....»»
Spectral evidence found for Dirac spinons in a kagome lattice antiferromagnet
A new study, published in a recent issue of Nature Physics, sheds light on the long-anticipated emergence of quasiparticles, akin to the famous Dirac particles obeying the relativistic Dirac equation. These quasiparticles, known as Dirac spinons, wer.....»»
Toyota"s massive $13.9B battery complex prepping to start production next year to power hybrids, EVs
Toyota's largest-ever investment in N.A. manufacturing is taking shape in rural N.C.; will ultimately provide batteries for locally built EVs, hybrids and PHEVs......»»
Group 1 Automotive"s Q1 acquisitions cost almost $700 million
The auto retailer also sold the Mike Smith Auto Complex in Beaumont, Texas, to Doggett Automotive Group in the first quarter......»»
Genes spatially organize for efficient mRNA splicing, study shows
The nucleus of each of your cells contains all the genetic information (the genome) necessary to build every type of cell and protein in your entire body. Like a complex library in a tiny space 50 times smaller than the width of a human hair, genes a.....»»
