American Sign Language (ASL) recognition systems often struggle with accuracy due to similar gestures, poor image quality and inconsistent lighting. To address this, researchers developed a system that translates gestures into text with 98.2% accuracy, operating in real time under varying conditions. Using a standard webcam and advanced tracking, it offers a scalable solution for […]

The NASA/ESA Solar Orbiter recently recorded the highest-ever concentration of a rare helium isotope (3He) emitted from the Sun. A Southwest Research Institute-led team of scientists sought the source of this unusual occurrence to better understand the mechanisms that drive solar energetic particles (SEPs) that permeate our solar system. SEPs are high-energy, accelerated particles including

A hopping, insect-sized robot can jump over gaps or obstacles, traverse rough, slippery, or slanted surfaces, and perform aerial acrobatic maneuvers, while using a fraction of the energy required for flying microbots.

A research team has developed an advanced delivery system that transports gene-editing tools based on the CRISPR/Cas9 gene-editing system into living cells with significantly greater efficiency than before. Their technology, ENVLPE, uses engineered non-infectious virus-like particles to precisely correct defective genes — demonstrated successfully in living mouse models that are blind due to a mutation.

Wear and tear on plastic products releases small to nearly invisible plastic particles, which could impact people’s health when consumed or inhaled. To make these particles biodegradable, researchers created plastics from plant starch instead of petroleum. An initial study shows how animals consuming particles from this alternative material developed health problems such as liver damage

When it comes to upgrading electrical and broadband infrastructure, new research shows that a ‘dig once’ approach is nearly 40% more cost effective than replacing them separately. The study also found that the greatest benefit comes from proactively undergrounding lines that are currently above ground, even if lines haven’t reached the end of their usefulness.

Researchers report their discovery of fluorescent pigments in the feathers of Long-eared Owls, that can only be seen by humans with the help of ultraviolet light.

Scientists have pioneered an influenza virus vector-based nasal spray vaccine platform and developed a nasal spray H5N1 avian influenza vaccine. During the early COVID-19 pandemic, this platform enabled the rapid development of a nasal spray vaccine in collaboration with mainland China’s Wantai BioPharm. After completing Phase 1-3 clinical trials, it was approved in 2022 as

While the daily ebb and flow of people across a city might seem chaotic, new research reveals underlying universal patterns. A study unveils fundamental spatiotemporal scaling laws that govern these population dynamics.

Researchers have developed a handheld device that could potentially replace stethoscopes as a tool for detecting certain types of heart disease.
