Heart failure patients who are vaccinated against COVID-19 have an 82% greater likelihood of living longer than those who are not vaccinated, according to research presented at Heart Failure 2024, a scientific congress of the European Society of Cardiology (ESC), held 11–14 May in Lisbon, Portugal. Heart Failure is a life-threatening syndrome affecting more than 64 million people worldwide.

“Patients with heart failure should be vaccinated against COVID-19 to protect their health,” said study author Dr. Kyeong-Hyeon Chun of the National Health Insurance Service Ilsan Hospital, Goyang, Republic of Korea.

“In this large study of patients with heart failure, COVID-19 vaccination was associated with a lower likelihood of contracting the infection, ...

Many artificial intelligence (AI) systems have already learned how to deceive humans, even systems that have been trained to be helpful and honest. In a review article published in the journal Patterns on May 10, researchers describe the risks of deception by AI systems and call for governments to develop strong regulations to address this issue as soon as possible.

“AI developers do not have a confident understanding of what causes undesirable AI behaviors like deception,” says first author Peter S. Park, an AI existential safety postdoctoral fellow at MIT. “But generally speaking, we think AI deception arises because a deception-based strategy turned out to be the best way to perform well at the given AI’s training task. Deception helps them achieve their goals.”

Astronomers have proposed a new theory to explain the origin of phosphorus, one of the elements important for life on Earth. The theory suggests a type of stellar explosion known as ONe novae as a major source of phosphorus.

After the Big Bang, almost all of the matter in the Universe was comprised of hydrogen.

Other elements were formed later, by nuclear reactions inside stars or when stars exploded in events known as novae or supernovae.

But there are a variety of stars and a variety of ways they can explode.

Astronomers are still trying to figure out which processes were important in creating the abundances of elements we see in the Universe.

In this study, Kenji Bekki, at The University of Western Australia, an...

Cornell researchers have developed a robotic feeding system that uses computer vision, machine learning and multimodal sensing to safely feed people with severe mobility limitations, including those with spinal cord injuries, cerebralpalsy and multiple sclerosis.

“Feeding individuals with severe mobility limitations with a robot is difficult, as many cannot lean forward and require food to be placed directly inside their mouths,” said Tapomayukh “Tapo” Bhattacharjee, assistant professor of computer science in the Cornell Ann S. Bowers College of Computing and Information Science and senior developer behind the system...
