Tech Xplore / Some of Meta's safety tools were 'designed to fail': Witness
A former employee testified Wednesday that some of Meta's safety tools for Facebook and Instagram were "designed to fail," contradicting the company's defense strategy in a landmark trial in California.
Phys.org / Scientists 'see' nanoscale forces, providing evidence of electric fields at the air‑water interface
Bubbles are round, and we know surface tension does that. But squeeze that gas-liquid boundary into a space only a few tens of nanometers wide—could other forces be at work?
Tech Xplore / AI bias isn't just an error in the algorithm, it's a chain of human decisions
In the United States, leading human resources software company Workday is facing a lawsuit over its use of AI-powered job screening tools that allegedly discriminated against applicants based on factors such as age, disability ...
Medical Xpress / Women make up nearly 70% of the global health workforce, even as the world faces a shortage of 34 million health workers
Women have driven the expansion of the global health workforce over the past three decades, yet substantial workforce shortages remain, according to a new study published in The Lancet Public Health. Researchers estimate ...
Phys.org / Tungsten may suffer more radiation damage in fusion reactors than expected
Fusion reactors, devices that generate energy by fusing light atomic nuclei at extremely high temperatures, could contribute to ongoing efforts aimed at producing electricity more sustainably. The extreme environment inside ...
Medical Xpress / AI model helps clinicians detect heart obstruction using routine ultrasound images
Mayo Clinic researchers have developed and externally validated an artificial intelligence (AI) model that can identify a potentially significant heart obstruction from routine ultrasound videos without relying on specialized ...
Medical Xpress / Why you move—not just how often—could affect dementia risk
For years, scientists have known that regular physical activity can help lower the risk of dementia. But new USC research suggests that it's not only the amount but also the activity's context—for work or for leisure—that ...
Medical Xpress / AI tool could help heart attack survivors receive tailored care, say experts
The health of heart attack survivors follows three distinct paths in the five years after their heart attack, say researchers from the University of Surrey. The research used an AI tool to find patterns that could not only ...
Phys.org / A single asteroid impact may explain the appearance of Mars' moon Deimos
Deimos, the smaller and outermost of Mars' two moons, is roughly oval in shape and has a deep depression at its south pole. Unlike its heavily scarred sister moon, Phobos, Deimos is covered by a loose layer of dust and rubble—a ...
Phys.org / 'Hidden stars' suggest that distant galaxies are much more massive than they appear
Astronomers have discovered that the most massive galaxies in the early universe contain far more small stars than expected. As a result, these early galaxies were likely much more massive than initial measurements suggested. ...
Tech Xplore / Engineers connect bacteria to create living transistors
MIT researchers have engineered bacteria that can function as transistors, allowing the team to create living "circuit boards" that can be printed onto a growth medium in a Petri dish.
Medical Xpress / Early immune 'checkpoint' could help explain why the same virus affects individuals so differently
Age, genetics and lifestyle are known to influence how people respond to viral infections. Scientists also know that differences in immune responses play an important role, but exactly how these factors shape the course of ...
