The academic community is growing increasingly concerned about students using ChatGPT for less than honest purposes as it has been found to be capable of not only writing essays for high school students, but passing some exams, such as parts of those used to license doctors and grant MBAs.

In two new papers posted on preprint servers, one team and another researcher independently tested the ability of ChatGPT to take and pass exams. In the first a team with members from AnsibleHealth, Inc., Brown University and OpenAI, Inc. describe testing they did to see how well ChatGPT could do on the United States Medical Licensing Examination (USMLE) and posted their results on the medRXiv preprint server.

In the second, Christian Terwiesch, the Andrew M. Heller Professor at Wharton School of the University of Pennsylvania, has posted a paper on Wharton’s preprint site, describing how he tested the chatbot’s ability to perform on the final exam of a typical Operations Management MBA core course and what he found.

Matter outflows in the form of jets are observed in astronomical systems at fast, medium and slow speeds. The fastest jets are highly relativistic, and travel very close to the speed of light. The origin, as well as many properties of the jets, is uncertain. Jet velocities seem to have a bi-modal distribution—some very fast and others slow, with a gap in velocities in between, which has long challenged experts. Bar-Ilan University researchers re-examined the data and have now seemingly solved the puzzle.

In many different galactic and extragalactic systems, emission of matter is commonly observed in the form of jets. The speed at which this occurs greatly varies. Alongside relatively slow jets associated with neutron stars or binary star systems, very fast, relativistic jets are seen at speeds very close to the speed of light. The fastest known jets are associated with a phenomenon known as gamma-ray bursts.

This phenomenon is characterized by an initial flash of gamma rays lasting for a few seconds, in which a strong emission of gamma radiation is visible. It is then followed by an afterglow lasting a much longer period of hours, days and even months. During this epoch, the emission subsequently fades and is observed as lower wavelengths, X-rays, ultraviolet, optical, infrared, and radio frequencies very late in the process.

Physical systems evolve at a particular speed, which depends on various factors including the system’s so-called topological structure (i.e., spatial properties that are preserved over time despite any physical changes that occur). Existing methods for determining the speed at which physical systems change over time, however, do not account for these structural properties.

Two researchers at Keio University in Japan have recently derived a speed limit for the evolution of physical states that also accounts for the topological structure of a system and of its underlying dynamics. This speed limit, outlined in a paper published in Physical Review Letters, could have numerous valuable applications for the study and development of different physical systems, including quantum technologies.

“Figuring out how fast a system state can change is a central topic in classical and quantum mechanics, which has attracted the great interest of scientists,” Tan Van Vu and Keiji Saito, the researchers who carried out the study, told Phys.org. “Understanding the mechanism of controlling time is relevant to engineering fast devices such as quantum computers.”

When scientists revealed they’d received radio signals from a galaxy nine billion light years away we all got a bit excited with the hopes that maybe this was finally aliens trying to contact us. We’re always on the lookout for extra-terrestrial life, even if plenty of our movies about finally meeting aliens involves them killing us horribly until we figure out how to kill them right back.

The World Futures Day by The Millennium Project, in cooperation with the Association of Professional Futurists (APF), Humanity+, Lifeboat Foundation, and the World Futures Studies Federation (WFSF), will take place on March 1st for the 10th year!

The call for facilitators is now open: support the World Futures Day by picking a one hour time slot where you will help to facilitate the discussion — such as the slot at 12 noon in your local area. If you want to be part of the team, please use this form.

In aging mouse livers, 40% of elongating RNA polymerases are stalled, biasing transcriptional output dependent on gene length. This transcriptional stress appears to be caused by endogenous DNA damage.

The project will be done in collaboration with Lockheed Martin and Nvidia.

The U.S. state agency, National Oceanic and Atmospheric Administration (NOAA), wants to transform how the weather is reported.
