WASHINGTON, D.C. — More than 1,100 experts have joined the Physicians Committee for Responsible Medicine in boycotting the medical journal Nutrients until it stops publishing egregious animal experiments that could have been ethically conducted in humans. The boycott, which also applies to Nutrients’ publisher, MDPI, comes after repeated requests to the journal’s editors asking them to institute sound editorial practices. A letter sent to those editors today, Nov. 20, 2023, says “As a community of scientists and health care professionals, we have ...

DURHAM, N.C. – A Duke Health analysis of breast cancer in North Carolina showed that the state’s urban counties had higher overall incidences of disease than rural counties, especially at early stages upon diagnosis.   The findings, appearing in the journal Scientific Reports, serve as a national template for assessing the impact of poor environmental quality across different stages of breast cancer, which is marked by highly diverse origins and mechanisms for spreading. North Carolina serves as a good model; it has a diverse population ...

URBANA, Ill. — Cesarean section (C-section) procedures have increased dramatically around the world in the recent decades. Overweight and obesity rates, common risk factors for pregnancy outcomes and for C-sections, are also on the rise — creating a major health issue in low- and middle-income countries. A new study from the University of Illinois Urbana-Champaign investigates how high obesity levels lead to hospital specializations that affect the frequency of C-sections in Mexico. “Of course, obesity is a medical factor for C-sections; however, when we started this project we did not believe it to be the ...

With the rapid development in computing power over the past few decades, machine-learning (ML) techniques have become popular in medical settings as a way to predict survival rates and life expectancies among patients diagnosed with diseases such as cancer, heart disease, stroke, and, more recently, COVID-19. Such statistical modeling helps patients and caregivers balance treatment that offers the highest chance of a cure while minimizing the consequences of potential side effects. A professor and his doctoral student at The University of Texas at Arlington have published a new model of predicting survival from ...

BIRMINGHAM, Ala. – It has been uncertain how Mycobacterium tuberculosis deflects the immune response in humans, though evidence has pointed to host immunometabolism — the intrinsic link between metabolism in immune cells and their immune function. The pathogen M. tuberculosis is known to disrupt a metabolic pathway called glycolysis in infected myeloid cells, which include macrophages, through an unclear mechanism. A more accurate understanding of this pathogenic mechanism could provide a target against the bacterium that caused 1.6 million deaths in 2021, along with 10 million new cases of tuberculosis every year. Now a study published ...

When researchers asked hundreds of people to watch other people shake boxes, it took just seconds for almost all of them to figure out what the shaking was for. The deceptively simple work by Johns Hopkins University perception researchers is the first to demonstrate that people can tell what others are trying to learn just by watching their actions. Published today in the journal Proceedings of the National Academy of Sciences, the study reveals a key yet neglected aspect of human cognition, and one with implications for artificial intelligence. “Just by looking ...

Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs. Using 700 years’ worth of wave data from more than a billion waves, scientists at the University of Copenhagen and University of Victoria have used artificial intelligence to find a formula for how to predict the occurrence of these maritime monsters. The new knowledge can make shipping safer. EMBARGOED CONTENT UNTIL MONDAY 20 NOVEMBER 2023 3 PM US EASTERN TIME Stories about monster waves, called rogue waves, have been the lore of sailors for centuries. But when a 26-metre-high rogue wave slammed into the Norwegian oil ...

Machine learning algorithms designed to diagnose a common infection that affects women showed a diagnostic bias among ethnic groups, University of Florida researchers found.  While artificial intelligence tools offer great potential for improving health care delivery, practitioners and scientists warn of their risk for perpetuating racial inequities. Published Friday in the Nature journal Digital Medicine, this is the first paper to evaluate fairness among these tools in connection to a women’s health issue. “Machine learning can be a great tool in medical diagnostics, but we found it can show bias toward different ethnic groups,” said Ruogu Fang, an associate ...

In recent years, many police departments have mandated or encouraged anti-bias training. This has occurred in response to government-imposed measures such as consent decrees or as a proactive attempt to enhance public perceptions of police following actions that have raised concerns about racially motivated and other discriminatory practices. In a new study, researchers evaluated the effectiveness of an anti-bias training intervention in one Californian jurisdiction. The study found that officers who received the training had improved performance scores (measured by Body Worn Camera footage), decreased disparity in how they treated different groups of people, ...

The widespread use of digital technologies and the Internet has spurred a new type of personal intrusion, known as cyberstalking. Incidences of cyberstalking have risen, with the U.S. Department of Justice estimating that more than 1.3 million people experience this type of victimization annually. A new study explored research to identify the factors associated with perpetration and victimization in cyberstalking. The study’s findings can inform the development of efforts to prevent and address cyberstalking. Conducted by a researcher at Sam Houston State ...

When the Hunga Tonga-Hunga Ha’apai volcano erupted on January 15, 2022 in the South Pacific, it produced a shock wave felt around the world and triggered tsunamis in Tonga, Fiji, New Zealand, Japan, Chile, Peru and the United States. It also changed the chemistry and dynamics of the stratosphere in the year following the eruption, leading to unprecedented losses in the ozone layer of up to 7% over large areas of the Southern Hemisphere, according to a recent study published in the Proceedings of the National ...

Pasadena, CA—Galaxies that formed just 2 to 3 billion years after the Big Bang are unusually hot and glow with light from surprising elements, like nickel, according to new work led by Carnegie’s Gwen Rudie and Northwestern University’s Allison Strom.
