    A simple twist fooled AI—and revealed a dangerous flaw in medical ethics

    A study by investigators at the Icahn School of Medicine at Mount Sinai, in collaboration with colleagues from Rabin Medical Center in Israel and other collaborators, suggests that even the most advanced artificial intelligence (AI) models can make surprisingly simple mistakes when faced with complex medical ethics scenarios.

    The findings, which raise important questions about how and when to rely on large language models (LLMs), such as ChatGPT, in health care settings, were reported in the…

  • A deadly virus no one talks about — and the HIV drugs that might stop it

    A deadly virus no one talks about — and the HIV drugs that might stop it

    Around 10 million people globally live with the life-threatening virus HTLV-1. Yet it remains a poorly understood disease that currently has no preventative treatments and no cure.

    But a landmark study co-led by Australian researchers could change this, after finding existing HIV drugs can suppress transmission of the HTLV-1 virus in mice.

    The study, published in Cell, could lead to the first treatments to prevent the spread of this virus that is endemic among many First Nations communities…

  • How many steps a day do you really need to take?

    How many steps a day do you really need to take?

    Walking just 7,000 steps per day can lower a person’s risk of certain health issues, according to a new study.

    “While the 10,000-step goal is widely known, it lacks a solid evidence base,” says Borja del Pozo Cruz, a physical activity epidemiologist at Universidad Europea de Madrid. “A target around 7,000 steps is more achievable for many and still provides substantial health benefits.”

    To understand how walking might impact a range of health conditions, del Pozo…

    Climate change may be pushing fungal allergy season earlier

    There’s no rest for allergy sufferers.

    Fungal allergy season gets going an average of 22 days earlier than it did 20 years ago, researchers report in the July GeoHealth. Rising temperatures and altered precipitation are linked to the new pattern, suggesting that climate change is making fungal allergy season worse. 

    “Two to three weeks is not trivial,” says Kai Zhu, an ecologist at the University of Michigan in Ann Arbor. People now need to prepare for fungal allergy…

    Breakthrough: How radiation helps the immune system kill cancer

    By sparking the immune system into action, radiation therapy makes certain tumors that resist immunotherapy susceptible to the treatment, leading to positive outcomes for patients, according to new research by investigators at the Johns Hopkins Kimmel Cancer Center Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Netherlands Cancer Institute. The work was supported by the National Institutes of Health.

    In the study, published July 22 in Nature Cancer, investigators dove deep into…

    Cancer cells go up in flames—thanks to this deep-sea sugar

    Promoting pyroptosis — an inflammatory form of programmed cell death — has become a promising treatment strategy for cancer. In research published in The FASEB Journal, investigators purified a long-chain sugar molecule, or exopolysaccharide, from deep-sea bacteria and demonstrated that it triggers pyroptosis to inhibit tumor growth.

    The compound, called EPS3.9, consists of mannose and glucose and is produced by the Spongiibacter nanhainus CSC3.9 bacterial strain and other members of the…
