After its "birth" in the Big Bang, the universe consisted mainly of hydrogen and a few helium atoms. These are the lightest elements in the periodic table. More-or-less all elements heavier than helium were produced in the 13.8 billion years between the Big Bang and the present
In the small fishing village where I grew up, we didn't have much. But we helped our neighbors, raised our children to respect the sea, and embraced an inclusive scientific methodology with a cross section of sex, race and gender among study participants that enriched the
The James Webb Space Telescope has discovered what appears to be a new record-holder for the most distant known galaxy, a remarkably bright star system that existed just 290 million years after the Big Bang, NASA said Thursday.
Astronomers from the Stanford University in California have performed joint X-ray and optical observations of a massive "spider" pulsar designated PSR J2215+5135. Results of the observational campaign, presented in a paper published May 22 on the pre-print server arXiv, provide
Nations aren't required to report their military climate pollution under the Paris Agreement. Experts say that should change
Solar Radiation Modification (SRM) is a suite of possible technologies to counteract global warming by reflecting incoming solar radiation.
UC Riverside scientists have discovered a highly effective, nontoxic, and less expensive way to lure hungry termites to their doom.
Researchers at the University of Virginia School of Engineering and Applied Science have figured out how to take a miracle material, one capable of extracting value from captured carbon dioxide, and do what no one else has: make it practical to fabricate for large-scale
Troubled aerospace giant Boeing will try once more to fly its first crew to the International Space Station aboard a Starliner spaceship on Saturday, after the last attempt was scrubbed hours before liftoff.
Scientists have discovered a highly effective, nontoxic, and less expensive way to lure hungry termites to their doom.
Mars has a distinct structure in its mantle and crust with discernible reservoirs, and this is known thanks to meteorites that scientists have analyzed. These results are important for understanding not only how Mars formed and evolved, but also for providing precise data that
An evolutionary biologist and a science fiction writer walk into a bar … and mull over survival. The post The Collapse Is Coming. Will Humanity Adapt? appeared first on Nautilus .
An accident of lighting uncovers Jewish, European, and Islamic origins. The post The Smartphone of the Middle Ages appeared first on Nautilus .
Biomarkers are small molecules of interest to researchers, because they can indicate underlying diseases, often even before symptoms even appear. However, detecting these markers can be challenging as they are often present in very low quantities, especially in the early stages
If matter falls into one end of a wormhole, it could heat up in a tornado of plasma hot enough to initiate nuclear fusion – and come blasting out the other end
The bird flu outbreak in U.S. dairy cows is prompting development of new, next-generation mRNA vaccines—akin to COVID-19 shots—that are being tested in both animals and people.
Guido Kusters created mathematical models to aid in the development of smart polymers, and he defended his Ph.D. thesis cum laude at the Eindhoven University of Technology Department of Applied Physics and Science Education on May 29.
Stromatolites are the earliest geological record of life on Earth. These curious biotic structures are made of algae carpets growing toward the light and precipitating carbonates. After their first appearance 3.48 Ga ago, stromatolites dominated the planet as the sole living
A simple statistical test can quickly guide humanitarian efforts in areas like Gaza and Ukraine impacted by war – and it could perform as well as more expensive, AI-powered methods
