Researchers are developing a way to incorporate one of the most human of characteristics — uncertainty — into machine learning systems. Human error and uncertainty are concepts that many artificial intelligence systems fail to grasp, particularly in systems where a human provides feedback to a machine learning model. Many of…
Orikhiv, Eastern Ukraine CNN — Rammed back into the bushes, out past destroyed Bradleys and ageing Humvees, the Soviet-era T72 lowers its turret to fire. Its targets are Russian positions, imperiled by Ukraine’s push south, just past the building over the horizon. Three rounds whistle into the distance, the tank…
Research from experts at Michigan Medicine, the Children’s Hospital of Philadelphia and Penn Medicine is breaking ground on new ways of treating blood disorders, such as sickle cell anemia, through gene therapy. To cure blood disorders, patients must undergo high dose chemotherapy and bone marrow transplantation. This requires a match…
A scientific journey decades in the making at Duke University has found a new antibiotic strategy to defeat gram-negative bacteria like Salmonella, Pseudomonas and E. coli, the culprits in many urinary tract infections (UTIs). The synthetic molecule works fast and is durable in animal tests. It works by interfering with…
People who take acid reflux medications called proton pump inhibitors for four-and-a-half years or more may have a higher risk of dementia compared to people who do not take these medications, according to new research published in the August 9, 2023, online issue of Neurology®, the medical journal of the…
In the ongoing search for a cure for Alzheimer’s disease, a burgeoning branch of medicine is bringing new hope. Stem cell therapies are already being used to treat various cancers and disorders of the blood and immune system. In a new proof-of-concept study, scientists at University of California San Diego…
New observations of mud cracks made by the Curiosity rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments, indicating that the red planet may have once seen seasonal weather patterns or even flash floods. The research was published today in Nature. “These exciting observations of mature mud…
In Parkinson’s disease, growing evidence targets neuroinflammation as essential for brain pathogenesis. But which group of immune cells that reside in the brain direct this inflammatory response? In a study published in Nature Communications, Ashley Harms, Ph.D., and colleagues at the University of Alabama at Birmingham, used a mouse model…
What do superheroes Deadpool and Elastigirl have in common? Each was used in a college anatomy class to add relevance to course discussions — Deadpool to illustrate tissue repair and Elastigirl, aka Mrs. Incredible, as an example of hyperflexibility. Instructors at The Ohio State University College of Medicine created a…

Fossilized feces preserve evidence of ancient parasites that infected an aquatic predator over 200 million years ago, according to a study published August 9, 2023 in the open-access journal PLOS ONE by Thanit Nonsrirach of Mahasarakham University, Thailand and colleagues. Parasites are a common and important component of ecosystems, but…
New research suggests that the US municipal bond market systemically misprices risk, as the pricing of municipal debt does not account for local physical climate risk, but does demand larger credit spreads from communities with a larger proportion of Black residents. Erika Smull of Duke University, US, and colleagues present…
While engaging in cell division research, Silke Hauf and members of her lab made a surprisingly quiet discovery. When cells express RNA, there is always some fluctuation, or noise, in how much RNA is produced. Hauf’s group found several genes whose noise dips below a previously established threshold, known as…
