Researchers introduce a new tool to measure bias in text-to-image AI generation models, which they have used to quantify bias in the state-of-the-art model Stable Diffusion.

Microscopic plastic particles have been found in the fats and lungs of two-thirds of the marine mammals in a graduate student’s study of ocean microplastics. The presence of polymer particles and fibers in these animals suggests that microplastics can …

Sodium, Potassium and zinc have all been promising contenders for lithium’s place in rechargeable batteries of the future, but researchers have added an unusual and more abundant competitor to the mix: chloride, the richest negatively charged ions in s…

The best heart rate for burning fat differs for each individual and often does not align with the ‘fat burning zone’ on commercial exercise machines, researchers report. Instead, the researchers said, clinical exercise testing — a diagnostic procedure…

A new analysis shows that infectious bacteria exposed to the antibiotic albicidin rapidly develop up to a 1,000-fold increase in resistance via a gene amplification mechanism.

Sugar-coated proteins called mucins are implicated in many diseases, including cancer. A team has now bioengineered an enzyme-based scissors that selectively cuts mucins off cancer cells, removing their ‘cloak of protection’ from the body’s immune system.

A new study finds that past changes in atmospheric CO2 and corresponding shifts in climate and vegetation played a key role in determining when and where early human species interbred.

A new study finds that around 1.12 million years ago a massive cooling event in the North Atlantic and corresponding shifts in climate, vegetation and food resources disrupted early human occupation of Europe.

An international research team details changes in DNA that researchers found are shared by humans and other mammals throughout history and are associated with life span and numerous other traits.

Plants orient their organs in response to the gravity vector, with roots growing towards gravity and shoots growing in the opposite direction. The movement of statoliths responding to the inclination relative to the gravity vector is employed for gravi…

Scientists working on Fermilab’s Muon g-2 experiment released the world’s most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown between theory and experiment that may uncover new part…

For now, cyborgs exist only in fiction, but the concept is becoming more plausible as science progresses. And now, researchers are reporting that they have developed a proof-of-concept technique to ‘tattoo’ living cells and tissues with flexible arrays…

Scientists can finally hunt down a harmful kind of human T cell. Immune cells called ex-T regulatory cells (exTregs) tend to be rare in the body and, so far, impossible to detect in human samples. A new study gives scientists a reliable way to find hum…

Long COVID can persist for at least a year after the acute illness has passed, or appear months later, according to the most comprehensive look yet at how symptoms play out over a year.

A change in just one letter in the code that makes up a cancer-causing gene can significantly affect how aggressive a tumor is or how well a patient with cancer responds to a particular therapy. A new, very precise gene-editing tool will enable scienti…

As butterflies flit among flowers, they don’t all view blossoms the same way. In a phenomenon called sexually dimorphic vision, females of some butterfly species perceive ultraviolet color while the males see light and dark. Biologists have discovered …

Scientists have validated a new approach to measuring extremely low gas pressures called CAVS, for cold atom vacuum standard. The quantum-based technique promises to be useful for applications such as chip manufacturing, quantum computing and gravitati…

Creating new technologically advanced sensors, scientists have engineered bacteria that detect the presence of tumor DNA in live organisms. Their innovation could pave the way to new biosensors capable of identifying various infections, cancers and oth…

Concealed guns significantly impact homicide rates and public safety, according to a new study that found an increase in homicides based on the number of concealed carry weapons licenses issued.

New research has demonstrated the safety and tolerability of a new drug treatment designed as a therapeutic intervention for spinal cord injury (SCI).
