A researcher made the discovery when a larva comb jelly mysteriously ‘replaced’ an adult comb jelly in his laboratory.
Anthropic’s new hire is preparing for a future where advanced AI models may experience suffering.
Surfers could be protected from future shark attacks following new discoveries about how to trick sharks’ visual systems made by Professor Nathan Hart, head of Macquarie University’s Neurobiology Lab, Dr. Laura Ryan and colleagues.
Using laser spectroscopy, the team were able to measure the nuclear radius of several isotopes of nobelium and fermium.
Unlike lighter regions of the nuclear chart, where upward kinks are observed crossing shell closures, the trend across a key neutron number is shown to be smooth. This indicates that nuclear shell effects due to a few nucleons have a reduced influence as the so-called superheavy elements are approached, and the nuclei behave more like a deformed liquid drop.
Researchers from the University of Liverpool’s Department of Physics, Professor Bradley Cheal and Dr. Charlie Devlin, contributed to the nobelium experimental activities of the study.
The authors demonstrate optical tweezing of microparticles and cells using an integrated optical phased array for the first time, increasing the standoff distance of integrated optical tweezers by over two orders of magnitude compared to prior work.
How did human culture become ecologically dominant? Morgan and Feldman re-examine existing theoretical accounts and propose that, contrary to previous belief, cumulative change and high transmission fidelity are not unique to human culture.
Scientists have created a compact spectral singlet lens that turns standard cameras into hyperspectral ones, reducing system size and complexity. This breakthrough could expand hyperspectral imaging into portable applications, with future improvements underway.
The information we gather shapes our understanding and perspectives of the world. For centuries, optics has sought to interpret the multidimensional data around us through the “toolbox” of light. In the 17th century, Sir Isaac Newton introduced the lens imaging formula and conducted his famous color spectrum experiment, laying foundational insights in the field.
Since then, lenses and spectrometers have been extensively studied as essential optical components for capturing information. Cascading these two components can allow us to acquire more information – both spatial and spectral data. However, such a configuration leads to tradeoffs among device footprint, spectral resolution, and imaging quality, impeding portability and miniaturization of hyperspectral cameras.
Researchers have developed a new method using the Allen Telescope Array to search for interplanetary radio communication in the TRAPPIST-1 star system.
A new technique allows astronomers to home in on planets beyond our solar system that are in line with each other and with Earth to search for radio signals similar, for example, to ones used to communicate with the rovers on Mars. Penn State astronomers and scientists at the SETI Institute spent 28 hours scanning the TRAPPIST-1 star system for these signs of alien technology with the Allen Telescope Array (ATA). This project marks the longest single-target search for radio signals from TRAPPIST-1. Although the team didn’t find any evidence of extraterrestrial technology, their work introduced a new way to search for signals in the future.
A paper describing the research was accepted for publication in the Astronomical Journal and is available online as a preprint.

In order to figure out how something came from nothing, we first need to explore the different types of nothing.
