Oct. 5, 2023 Researchers have developed a 'quantum ruler' to measure and explore the strange properties of multilayered sheets of graphene, a form of carbon. The work may also lead to a new, miniaturized standard for electrical resistance that could calibrate electronic devices directly on the factory floor, eliminating the need to send them to an off-site standards laboratory. ...

Oct. 5, 2023 A fundamental discovery about the Fischer Tropsch process, a catalytic reaction used in industry to convert coal, natural gas or biomass to liquid fuels, could someday allow for more efficient fuel production. Researchers discovered previously unknown self-sustained oscillations in the Fischer Tropsch process. They found that unlike many catalytic ...

Oct. 5, 2023 Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what give metals their strength and workability, but they can also make materials fail catastrophically – which is what happens every time you pop the ...

Oct. 6, 2023 Astronomers have gotten very good at spotting the signs of planet formation around stars. But for a complete understanding of planet formation, we also need to study examples where planet formation has not yet started. Looking for something and not finding it can be even more difficult than finding it sometimes, but new detailed observations of the young star DG Taurus show that it has a smooth ...

Oct. 6, 2023 The central question in the ongoing hunt for dark matter is: what is it made of? One possible answer is that dark matter consists of particles known as axions. A team of astrophysicists has now shown that if dark matter consists of axions, it may reveal itself in the form of a subtle additional glow coming from pulsating ...

Oct. 3, 2023 A new study posits that the large, approximately 5-kilometer-long mounds that dominate the appearance of the larger lobe of the pristine Kuiper Belt object Arrokoth are similar enough to suggest a common origin. The study suggests that these “building blocks” could guide further work on planetesimal formational ...

Oct. 3, 2023 Agriculture in Syria started with a bang 12,800 years ago as a fragmented comet slammed into the Earth’s atmosphere. The explosion and subsequent environmental changes forced hunter-gatherers in the prehistoric settlement of Abu Hureyra to adopt agricultural practices to boost their chances for ...

Oct. 5, 2023 A new attempt to predict earthquakes has raised hopes that artificial intelligence could one day be used to limit earthquakes’ impact on lives and economies. The AI algorithm correctly predicted 70% of earthquakes a week before they happened during a seven-month trial in China. The system is limited because the AI needs an extensive database and years of seismic recordings to train itself ...

Oct. 5, 2023 Researchers have developed a new open-source computational method, dubbed Spectra, which improves the analysis of single-cell transcriptomic data. By guiding data analysis in a unique way, Spectra can offer new insights into the complex interplay between cells — like the interactions between cancer cells and immune cells, which are critical to improving immunotherapy ...
