GPT-4 for radiology.
As the benefits of AI in healthcare continue to emerge, we investigate GPT-4’s potential in radiology. Learn about research exploring GPT-4’s potential in assisting report structuring, classifying diseases, and generating comprehensive findings summaries:
Researchers report that they have developed a new composite material designed to change behaviors depending on temperature in order to perform specific tasks. These materials are poised to be part of the next generation of autonomous robotics that will interact with the environment.
The new study conducted by University of Illinois Urbana-Champaign civil and environmental engineering professor Shelly Zhang and graduate student Weichen Li, in collaboration with professor Tian Chen and graduate student Yue Wang from the University of Houston, uses computer algorithms, two distinct polymers, and 3D printing to reverse engineer a material that expands and contracts in response to temperature change with or without human intervention.
Life expectancy and healthy aging in mice can be determined by a protein present in some cells of the immune system, according to a study published in the journal Cell Reports. When this protein—known as the CD300f immune receptor—is absent, animal models have a shorter life expectancy and suffer from pathologies associated with cognitive decline and premature aging, especially in females.
“Our study indicates that alterations in immune system cells, for instance, in macrophages and microglia, can determine the healthy aging degree in mice,” notes Hugo Peluffo, leader of this study and member of the Faculty of Medicine and Health Sciences and the Institute of Neurosciences (UBneuro) of the University of Barcelona.
Understanding how the CD300f immune receptor —and the myeloid cells of the immune system—can determine by themselves the onset rate of aging-associated pathologies, “will help to better understand this process, and it will contribute to the design of strategies to regulate its action. For instance, using the immune receptor CD300f as a target in biomedicine,” notes the expert. “Also, our team has previously shown that some variants of the CD300f immune receptor could be useful as biomarkers in patients.”
NASHVILLE, Tenn. (AP) — A ransomware attack has prompted a healthcare chain that operates 30 hospitals in six states to divert patients from at least some of its emergency rooms to other hospitals, while putting certain elective procedures on pause, the company announced.
In a statement Monday, Ardent Health Services said the attack occurred Nov. 23 and the company took its network offline, suspending user access to its information technology applications, including the software used to document patient care.
The Nashville, Tennessee-based company said it cannot yet confirm the extent of any patient health or financial information that has been compromised. Ardent says it reported the issue to law enforcement and retained third-party forensic and threat intelligence advisors, while working with cybersecurity specialists to restore IT functions as quickly as possible. There’s no timeline yet on when the problems will be resolved.
In a world that seems inexorably drawn towards an all-electric future, Toyota has consistently taken a different road. The Japanese automaker remains skeptical about an exclusive reliance on electric vehicles (EVs). While it’s true that Toyota has some exciting EVs in the pipeline for the upcoming year, they are also actively exploring alternative energy sources. However, a recent development could potentially turn the tables on the EV revolution — an ammonia-powered engine for passenger vehicles.

At an MIT event in March, OpenAI cofounder and CEO Sam Altman said his team wasn’t yet training its next AI, GPT-5. “We are not and won’t for some time,” he told the audience.
This week, however, new details about GPT-5’s status emerged.
In an interview, Altman told the Financial Times the company is now working to develop GPT-5. Though the article did not specify whether the model is in training—it likely isn’t—Altman did say it would need more data. The data would come from public online sources—which is how such algorithms, called large language models, have previously been trained—and proprietary private datasets.
Nvidia co-founder Curtis Priem lives off the grid and spends all his money on supporting his alma mater. However, he could have been a multi-billionaire had he kept hold of his Nvidia shares until 2023.

Scientists from the Planetary Science Institute have uncovered evidence of potential salt glaciers on Mercury, opening a new frontier in astrobiology by revealing a volatile environment that might echo habitability conditions found in Earth’s extreme locales.
“Our finding complements other recent research showing that Pluto has nitrogen glaciers, implying that the glaciation phenomenon extends from the hottest to the coldest confines within our solar system. These locations are of pivotal importance because they identify volatile-rich exposures throughout the vastness of multiple planetary landscapes,” said Alexis Rodriguez, lead author of the paper “Mercury’s Hidden Past: Revealing a Volatile-Dominated Layer through Glacier-like Features and Chaotic Terrains” that appears in the Planetary Science Journal.
PSI scientists Deborah Domingue, Bryan Travis, Jeffrey S. Kargel, Oleg Abramov, John Weirich, Nicholas Castle and Frank Chuang are co-authors of the paper.
A new ingestible capsule can monitor vital signs from within the patient’s GI tract. The sensor could be used for less intrusive monitoring of sleep disorders such as sleep apnea, or for detecting opioid overdoses.
Diagnosing sleep disorders such as sleep apnea usually requires a patient to spend the night in a sleep lab, hooked up to a variety of sensors and monitors. Researchers from MIT, Celero Systems, and West Virginia University hope to make that process less intrusive, using an ingestible capsule they developed that can monitor vital signs from within the patient’s GI tract.
The capsule, which is about the size of a multivitamin, uses an accelerometer to measure the patient’s breathing rate and heart rate. In addition to diagnosing sleep apnea, the device could also be useful for detecting opioid overdoses in people at high risk, the researchers say.
