Anyone can ask ChatGPT to answer a question or perform a task. But the popular chatbot is particularly useful for workers in three specific industries, according to OpenAI CEO Sam Altman. “Coding is probably the single area from a productivity gain we’re most excited about today. It’s massively deployed and at scaled usage, at this … Read more
Bluegreen Aphid on leaf. Credit: Cesar Australia For the first time, researchers in Australia have documented insecticide resistance in field-collected populations of bluegreen aphids, Acyrthosiphon kondoi—a worldwide pest of pulses and other legume crops. The study, published in Pest Management Science, serves as a warning to growers globally and highlights the need for new strategies … Read more
NASA’s Spirit and Opportunity Mars rovers landed on the Red Planet on Jan. 3 and 24, 2004, respectively. This image shows a view Opportunity captured of its own shadow on July 26 of that year, the 180th Martian day, or sol, of its mission.

For the very first time, a successfully cloned rhesus monkey has survived to adulthood, according to a study published Tuesday in Nature Communications. The primate’s name is Retro and he is already over two years old. Retro may be the first of his species to be cloned by scientists, but he’s not the first monkey. … Read more
Fig. 1. Schematic of our experimental setup using the MZI for observations of WPS of photons. Credit: Zhong-Xiao Man Understanding the nature of quantum objects’ behaviors is the premise for a reasonable description of the quantum world. Depending on whether the interference can be produced or not, the quantum object is endowed with dual features … Read more
Using a bioluminescent substrate that reacts with SARS-CoV-2 spike protein (shown in the insert), researchers have devised a potential one-minute COVID-19 test. Credit: Ryo Nishihara Cold, flu and COVID-19 season brings that now-familiar ritual: swab, wait, look at the result. But what if, instead of taking 15 minutes or more, a test could quickly determine … Read more

The San Diego Zoo Wildlife Alliance and DNA-sequencing giant Illumina are examining the genetic information of nearly 100 koalas spanning 30 years to get a better understanding of koala retrovirus, or KoRV. … Read more
(a) Experimental Setup: A charged microparticle is trapped using a laser beam in a parabolic trap. Temperature control is achieved through a noisy electrical signal simulating a thermal bath. (b) Evolution Kinematics: The evolution kinematics are analyzed between two initial states—one hotter and one colder than the intermediate target state, equidistant from both. Results show … Read more
Hebbian dynamics produce power–law connection strengths. Credit:bioRxiv (2022). DOI: 10.1101/2022.05.30.494086 A study by physicists and neuroscientists from the University of Chicago, Harvard and Yale describes how connectivity among neurons comes about through general principles of networking and self-organization, rather than the biological features of an individual organism. The study, titled “Heavy–tailed neuronal connectivity arises from … Read more
Credit: Pixabay/CC0 Public Domain Japan, whose unmanned “sniper” probe will attempt a lunar landing on Saturday, is one of many countries and private companies launching new missions to the moon. It is a feat so far only achieved by four nations—the United States, the Soviet Union, China and most recently India—with spacecraft often losing communication … Read more
