A German flying taxi firm was Tuesday saved from collapse after investors swooped in to take it over, in a case that has fired debate about support for the country's startup scene.... Read more

For homeowners, moisture buildup can cause the biggest headaches. Mold grows on drywall and wood-based materials, creeping along walls, floors and ceilings. Building materials begin to erode and rot. As insulation becomes damaged, the home's energy-efficiency decreases. Even human health suffers, as moisture also leads to air-quality issues.... Read more

A groundbreaking advancement in technology is paving the way for mobile phones and other electronic devices to recharge simply by being kept in a pocket. This innovative system enables wireless charging throughout three-dimensional (3D) spaces, encompassing walls, floors, and air.... Read more

Johns Hopkins computer scientists have created an artificial intelligence system capable of "imagining" its surroundings without having to physically explore them, bringing AI closer to humanlike reasoning.... Read more

Researchers have developed a laser-based artificial neuron that fully emulates the functions, dynamics and information processing of a biological graded neuron. With a signal processing speed of 10 GBaud—a billion times faster than its biological counterparts—the new laser graded neuron could lead to breakthroughs in fields like artificial intelligence and...

Max Planck Institute for Sustainable Materials (MPI-SusMat) researchers have transformed dealloying—traditionally seen as a corrosive, destructive process—into a groundbreaking method for creating lightweight, high-strength alloys. By combining dealloying with alloying in a single step, the team developed nano-porous martensitic alloys using reactive gases like ammonia, which simultaneously remove oxygen and... Read more

Wearable haptic devices, which provide touch-based feedback, can provide more realistic experiences in virtual reality, assist with rehabilitation, and create new opportunities for silent communication. Currently, most of these devices rely on vibration, as pressure-based haptics have typically required users to wear stiff exoskeletons or other bulky structures.... Read more

Scientists in South Korea have developed swarms of tiny magnetic robots that work together like ants to achieve Herculean feats, including traversing and picking up objects many times their size.... Read more

In the art world, a certificate of authenticity is the traditional guarantee of originality. Typically issued by artists, art dealers or private sellers, these certificates serve to distinguish genuine works from forgeries. The problem is that the actual proof of originality often amounts to little more than a signature on... Read more

A newly developed automated system can add vowel signs to computerized Arabic texts, enabling learners and speakers to read them in an easy and accurate manner, scientists reveal.... Read more

A team led by Prof. Jang Kyung-In from the Department of Robotics and Mechatronics Engineering (DGIST) has developed a three-dimensional stretchable piezoelectric energy harvester that can harvest electrical energy using body movements. The device is to be used as a wearable energy harvester as it can be attached to the... Read more

Sign language serves as a sophisticated means of communication vital to individuals who are deaf or hard-of-hearing, relying on hand movements, facial expressions, and body language to convey nuanced meaning. American Sign Language exemplifies this linguistic complexity with its distinct grammar and syntax.... Read more

Having access to virtual worlds from your home computer via your web browser and being able to interact with others in a secure and private manner: that is the promise of metaverse platforms.... Read more

Civil and systems engineers at Johns Hopkins University have turned a longstanding problem with 3D printers into a multifunctional feature: The team developed a new printing technique that solves the fundamental weakness between the layers created during 3D printing. This work, which appears in Advanced Materials, has the potential to... Read more

More than one in four people currently integrate speech recognition into their daily lives. A new algorithm developed by a University of Copenhagen researcher and his international colleagues makes it possible to interact with digital assistants like "Siri" without any internet connection. The innovation allows for speech recognition to be... Read more
