A research team at the Korea Institute of Geoscience and Mineral Resources (KIGAM) has developed a technology that converts wet spent coffee grounds directly into high-quality biochar in just 90 seconds, with no drying or oil removal required. The breakthrough offers a fast, energy-efficient path to turning high-moisture organic waste into valuable fuel and carbon materials. The study, led by Dr. Taejun Park in collaboration with GodTech Co., Ltd., was published in the Chemical Engineering Journal, one of the world's leading journals in chemical engineering.

Unmanned aerial vehicles (UAVs), commonly known as drones, are now widely used for various purposes, ranging from filmmaking and aerial photography to industrial inspection, precision farming and reaching obstructed areas during emergency response missions. While many existing drones can move swiftly in their surroundings and circumvent large obstacles, most still struggle in cluttered environments. In addition, they are often unable to execute maneuvers that would allow them to safely pass through small gaps or reach secluded areas.

The human brain actively keeps "learning" in balance by holding on to what matters and letting go of what does not. Researchers in Korea have now reproduced this ability in a semiconductor device, using the color of light to strengthen (remember) or weaken (forget) an artificial synapse's memory. Remarkably, the key ingredient is a material "defect" that engineers usually try to eliminate. The study appears in Nature Communications.

One of the greatest weaknesses of AI agents that read and understand vast amounts of enterprise data is "hallucination"—the generation of plausible-sounding but factually incorrect information. KAIST researchers have developed a next-generation database technology capable of understanding documents, data and relationships among entities all at once.

Humanoid robots able to perform tasks from grape harvesting to welcoming visitors were front and center at France's Vivatech trade fair this week, with European firms looking to fill niches beyond what dominant Chinese giants can offer.

A robot with expressive eyebrows designed to perform basic tasks and free up health care workers is getting a trial run at a hospital in Milan.

If you ever need help in the kitchen cutting fish into appetizing bites, a new three-armed robot may be able to help. And that's no easy feat for robots. While they are generally good at picking up rigid objects, something slippery that can change shape when touched, such as a fish, poses a range of challenges. Then, if you add slicing into the mix, it becomes even more difficult because the robot has to cope with the fish changing shape as it is handled and cut.

Barcode readers excel at quickly identifying groceries and other products. Could a similar idea work at industrial recycling facilities to make sorting different plastics quicker and more cost-effective? The answer, according to a University at Buffalo research team, is yes.

In April, Galileo marked a step forward with the deployment of a new signal component, known as E5a Quasi Pilot, on 12 satellites of Europe's satellite navigation constellation. This upgrade makes Galileo signals easier to access, particularly on emerging mass-market, low-power devices used for Internet of Things and smart-city applications.

The squawks of macaws, the smell of wet earth after rain and a swirl of colors will transport visitors from a Los Angeles museum to the heart of the Amazon rainforest—or rather, an AI version of it.

Humanoid robots are no longer science fiction: They can take on tasks that challenge humans and have the potential to play an important role in industry, services or private households in the future. At Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), researchers are working on hardware and software for human-like robots. Dr. Sebastian Reitelshöfer from the FAU Chair of Manufacturing Automation and Production Systems explains in an interview how humanoid robots could support us in the future and why this future technology on two legs could be an opportunity for northern Bavarian industry.

Battery energy storage systems can play a key role in future renewable energy systems—but how they are operated is crucial for both profitability and battery life, according to research by Meryem Ahouad at Chalmers University of Technology.

More than 1.5 billion people worldwide are expected to watch the 2026 World Cup finals. With that many fans scrutinizing every pass, touch and goal, FIFA is leaning on advanced computer vision technology to help referees make faster, more accurate calls on the way to crowning this year's victors.

A prototype rover built with a new design for tackling rugged terrain is helping teams refine capabilities that could one day be used on future lunar and Red Planet missions.

Scientists have revolutionized the way metals are made by using lower and slower heating of alloys to control how atoms self-organize during material manufacturing. The discovery, published in Science by Monash University engineers in Australia, essentially rewrites what has been a century-old approach to alloy design.

Clarkson University researchers have developed a new mathematical tool that could make artificial intelligence systems more accurate, controllable and useful across applications ranging from image editing to drug discovery.

Over the last two decades, annual carbon dioxide emissions in the U.S. have declined significantly. In recent years, however, this trend has slightly reversed, likely due to the explosive growth of data centers. As energy-intensive data centers proliferate, their emissions could undo years of decarbonization efforts. According to an analysis of data in the public domain, capturing and storing emissions in underground reservoirs could halt this reversal, researchers report in Energy & Fuels.

Battery-electric trucks are expected to play the leading role in the future decarbonization of road freight transport. At the same time, a new study from Chalmers University of Technology shows that hydrogen could remain important for the heaviest trucks operating over long distances.

University of Adelaide researchers have developed a wearable glove that uses heat, touch and physical objects to transform data into a sensory experience. The prototype, called ThermoPhy, was developed as part of a remote internship run by the Australian Research Center for Interactive and Virtual Environments (IVE) at the University of Adelaide.

Fayas Malik Kanchiralla, a postdoctoral researcher at the Department of Environmental and Energy Sciences, together with colleagues has analyzed how the International Maritime Organization's (IMO) proposed climate framework affects shipping's transition to new marine fuels.
