Researchers at the Earth-Life Science Institute (ELSI) at the Institute of Science Tokyo and collaborators investigated how mixed lipid membranes respond to repeated freeze thaw cycles that mimic temperature fluctuations on the early Earth.
The study, led by biologists at the Department of Biology and research centers Nordcee and the Danish Center for Hadal Research, focuses on so called marine snow.
Cosmic birefringence refers to a small rotation in the polarization direction of the cosmic microwave background, the relic radiation from the Big Bang that preserves information about the early universe.
By tuning in to low frequency radio waves, the survey provides a strikingly different view of the cosmos than optical telescopes, tracing relativistic particles spiralling through magnetic fields.
Earth's magnetic field is generated by movement in its liquid iron outer core - a process known as a dynamo - but larger rocky worlds like super-earths might have solid or fully liquid cores that cannot produce magnetic fields in the same way.
Gas giants, such as Jupiter and Saturn in our own solar system, are large planets made mostly of helium and/or hydrogen around a dense core, but they have a bit of an identity crisis.
The study used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to image 24 debris discs made of dust, gas and rocks orbiting stars in systems between roughly 10 million and two billion years old.
The Hubble tension arises because two precise approaches to determining the Hubble constant give significantly different results, despite drawing on high quality data.
In a Q&A conducted by SLAC, Josh Frieman and Risa Wechsler discuss dark energy, the Dark Energy Survey and the Vera C. Rubin Observatory.
In work published in Nature Catalysis, the researchers demonstrate that the bacterium Escherichia coli can be engineered to produce new-to-nature molecules in vivo using light-driven enzymatic reactions.
A team from the Laboratory of Atmospheric and Planetary Physics (LPAP) at the University of Liege has used NASA's Juno spacecraft to resolve, for the first…
Mike Fincke, 58, said he's "doing very well and continuing standard post-flight reconditioning" at NASA's center in Houston.
The flip side of the gold rush surrounding AI is the risk of job disruption, online abuse and the heavy electricity consumption of data centres.
The work, which was previously published in the journal npj Microgravity, will be highlighted at the 70th Biophysical Society Annual Meeting in San Francisco…
On stock markets, a rally across Asia following gains by US tech heavyweights failed to bolster indices in Europe and the United States, where traders focussed on a string of corporate results.
"I would like Spain to heed this call, I would like Italy and France to hear it even more strongly, this call to increase defence spending, as Poland, Germany and the Scandinavian countries have done," Kosiniak-Kamysz said in an interview.
