Big Science Art: Openverse’s black hole spins visualization on NATURE journal
HANGZHOU, China, Nov. 1, 2023 /PRNewswire/ — The following is a report about Openverse originally published by WSJ.China. Humanity has always been curious about the supermassive black hole in the center of the galaxy. “A black hole is the most ideal and simplest celestial body to verify the correctness of the theory of general relativity,…

Husker team partnering with communities to enhance biodiversity
Students who live in rural and tribal communities are surrounded by stunning examples of biodiversity: Grasses, prairies, flowers and wildlife feature more prominently in these youths’ lives compared to many of their peers in urban areas. But systemic factors like geographic isolation, higher rates of poverty and limited educational resources sometimes minimize these students’ opportunities to…

Researchers revolt against weekend conferences
Thanks to its offer of free childcare, Jessica Osterhout was able to attend the 2023 American Association of Immunologists meeting in Washington DC.Credit: Jessica Osterhout Amanda Sierra never intended to organize a weekend conference. “It is extremely disrespectful to start a conference over the weekend; it is almost insulting for the intrusion on family time…

Author Correction: Like-minded sources on Facebook are prevalent but not polarizing
Correction to: Nature https://doi.org/10.1038/s41586-023-06297-w Published online 27 July 2023 In the version of this article initially published, the variable described in Supplementary Table 36 as measuring Facebook “strikes” for violations of content policies against “Coordinated Inauthentic Behavior” (CIB) is inaccurate and does not reflect enforcement of the actual CIB policy, which is not a content-level…

Ultra-sensitive pressure sensing capabilities of defective one-dimensional photonic crystal
Abstract Present research work deals with the extremely sensitive pressure-sensing capabilities of defective one-dimensional photonic crystal structure (GaP/SiO2)N/Al2O3/(GaP/SiO2)N. The proposed structure is realized by putting a defective layer of material Al2O3 in the middle of a structure consisting of alternating layers of GaP and SiO2. The transfer matrix method has been employed to examine the…

Early-career factors largely determine the future impact of prominent researchers: evidence across eight scientific fields
Abstract Can we help predict the future impact of researchers using early-career factors? We analyze early-career factors of the world’s 100 most prominent researchers across 8 scientific fields and identify four key drivers in researchers’ initial career: working at a top 25 ranked university, publishing a paper in a top 5 ranked journal, publishing most…

A versatile high-average-power ultrafast infrared driver tailored for high-harmonic generation and vibrational spectroscopy
Abstract We report on an ultrafast infrared optical parametric chirped-pulse amplifier (OPCPA), pumped by a 200-W thin-disk Yb-based regenerative amplifier at a repetition rate of 100 kHz. The OPCPA is tunable in the spectral range 1.4–3.9 (upmu )m, generating up to 23 W of < 100-fs signal and 13 W of < 200-fs idler pulses…

Keeping secrets in a quantum world
In July 2022, a pair of mathematicians in Belgium startled the cybersecurity world. They took a data-encryption scheme that had been designed to withstand attacks from quantum computers so sophisticated they don’t yet exist, and broke it in 10 minutes using a nine-year-old, non-quantum PC. “I think I was more surprised than most,” says Thomas…

Cells with cFos and 53BP1 immunoreactivity in the CA1 region of the hippocampus from a young female apolipoprotein E4 (apoE) targeted replacement mouse 1.5 h after fear conditioning
Representative images of cFos and 53BP1 immunoreactive cells in the CA1 region of the hippocampus from a young female apolipoprotein E4 (apoE) targeted replacement mouse 1.5 h after fear conditioning. Images were taken of young (3 month) and middle-aged (12 months) male and female mice that were never exposed to fear conditioning (behaviorally naïve), euthanized 1.5 h…

How would a starfish wear trousers? Science has an answer
Starfishes are weirdly shaped animals. Scientists have long puzzled over how a starfish body equates to the more typical animal arrangement of a head on one end and trunk or tail on the other. Humans wear trousers on the bottom of their trunks, so you could extrapolate out from that to suggest solutions to the…
