Researchers have developed a sustainable catalyst that increases its activity during use while converting carbon dioxide (CO2) into valuable products. This discovery offers a blueprint for designing next-generation electrocatalysts.

Artificial Intelligence of Things (AIoT) is becoming immensely popular because of its widespread applications. In a groundbreaking study, researchers present a new AIoT framework called MSF-Net for accurately recognizing human activities using WiFi signals. The framework utilizes a novel approach that combines different signal processing techniques and a deep learning architecture to overcome challenges like environmental interference and achieve high recognition accuracy.

Researchers have designed an alternative, autonomous observational method to monitor the Arctic's melting ice, which holds promise for improving the autonomy of marine vehicles, aiding in maritime missions, and gaining a deeper understanding of how melting Arctic sea ice affects marine ecosystems. Their conceptual design features a small waterplane area twin hull vessel that acts as a docking and charging station for autonomous underwater vehicles and unmanned aerial vehicles, using solar and turbine energy to enable continuous monitoring.

An expert in energy technologies uses AI tools to investigate the impact of extreme weather on solar-powered and electrified homes and uncover their unique vulnerabilities and develop insights on how they handle harsh conditions.

Scientists have successfully developed a gastric cancer model using 3D bioprinting technology and patient-derived cancer tissue fragments. This innovative model preserves the characteristics of actual patient tissues and is expected to rapidly evaluate and predict individual patient drug responses.

Researchers have achieved total chemical synthesis of the psychoactive compound ibogaine and its analogs from pyridine. The discovery will make it easier to explore the therapeutic possibilities of ibogaine.

A biomaterial that can mimic certain behaviors within biological tissues could advance regenerative medicine, disease modeling, soft robotics and more, according to researchers.

An international team of researchers has shown that countless tiny ice quakes take place in one of Greenland's mightiest ice streams. This finding will allow the flowing of the ice sheet and associated changes in sea level to be estimated more accurately.

Mantis shrimp withstand repeated high-impact forces without structural damage. Researchers discovered the shrimp's clubs feature a protective pattern that controls how stress waves travel through its body. The patterns resemble herringbone and twisted, corkscrew arrangements. Insights from this discovery could inspire advanced protective materials for reducing blast-related injuries.

Nearly every disease has an inflammatory component, but blood tests can't pinpoint inflammation in specific organs or tissues in the human body. Now researchers have developed a method to detect inflammation using antibodies, potentially leading to blood tests for disease-specific biomarkers such as for heart disease, Alzheimer's disease and various cancers. Their breakthrough also holds promise for drug discovery.

Electric sparks are used for welding, powering electronics, killing germs or for igniting the fuel in some car engines. Despite their usefulness, they are hard to control in open space, they split into chaotic branches that tend to go towards the closest metallic objects. A recent study uncovers a way of transporting electricity through air by ultrasonic waves. The level of control of the electric sparks allows to guide the spark around obstacles, or to make it hit specific spots, even into non-conductive materials.

Researchers created platinum-mixed metallic magnetic nanofilms that are 5x more efficient -- the ultimate energy-saving solution.

A team of international researchers has developed an innovative approach to uncover the secrets of dark matter in the cosmos. They are searching for dark matter using atomic clocks and cavity-stabilized lasers.

Epoxy resins are coatings and adhesives used in a broad range of familiar applications, such as construction, engineering and manufacturing. However, they often present a challenge to recycle or dispose of responsibly. Now a team of researchers has developed a method to efficiently reclaim materials from a range of epoxy products for reuse by using a novel solid catalyst.

In a new study, scientists show that a mix of policy measures, including both technological solutions and behavioral changes, can significantly reduce greenhouse gas (GHG) emissions from energy use in buildings and transport.
