A research team in South Korea has developed the world’s first fully functional electric motor constructed entirely without metal components. Replacing traditional copper coils with carbon nanotubes (CNTs), this breakthrough marks a major step toward ultra-lightweight transportation systems. The CNT motor demonstrates a 133% improvement in electrical conductivity and weighs 80% less than conventional designs.

Lightweighting remains a key challenge in the development of electric vehicles, drones, and spacecraft. Lighter components not only reduce energy consumption but also increase battery efficiency and extend operational range. The newly developed motor, created by researchers at the Korea Institute of Science and Technology (KIST), successfully powers a toy car at speeds exceeding half a meter per second, showcasing its potential in practical applications.

In the microscopic world of bacteria, survival depends on innovative defense systems that can neutralize viral invaders. While CRISPR-Cas9 has become widely known as both a bacterial immune mechanism and a revolutionary gene-editing tool, researchers continue to uncover additional layers of bacterial defense. One of the latest discoveries adds a surprising twist to how these tiny organisms protect themselves from viral attack.

Scientists at Rockefeller University and Memorial Sloan Kettering Cancer Center have identified a powerful new immune protein named Cat1. This protein belongs to a group known as CARF effectors, which are activated when viruses, particularly bacteriophages, attempt to infect a bacterial cell. CARF effectors help prevent viral spread by forcing the infected cell into a shutdown mode, effectively containing the threat before it reaches neighboring cells.

Silicon has long been the cornerstone of semiconductor technology, powering everything from smartphones and computers to electric vehicles. However, this reigning material may soon face significant competition as researchers develop new alternatives that could transform electronics in the coming years.

A research team at Penn State has successfully built a computer capable of performing simple operations using two-dimensional (2D) materials instead of silicon. These 2D materials are not only thinner at the atomic scale but also maintain their electronic properties even when scaled up, offering promising advantages over traditional silicon.

Researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have developed a groundbreaking nanopore sensing platform capable of detecting single biomolecules. Their work, recently published in Proceedings of the National Academy of Sciences, offers promising advancements for solid-state, label-free DNA sequencing, with far-reaching implications for precision medicine.

Nanopore sensors operate by detecting changes in ionic current as individual molecules pass through nanoscale openings. These devices come in two primary forms: biological nanopores and solid-state nanopores. While biological nanopore sequencing has already reached commercial use, engineers at Illinois Grainger aimed to develop a solid-state alternative that is more compatible with scalable manufacturing.

The Quantum Systems Accelerator (QSA) continues to make major strides toward building flexible and stable quantum computers capable of solving problems far beyond the reach of today’s classical machines. Through a series of collaborative efforts across top U.S. research institutions, QSA scientists are addressing the engineering challenges at the heart of quantum computing and making significant progress on key architectures and techniques.

Trapped-ion systems remain one of the most advanced platforms in quantum computing. These systems trap and manipulate ions using electric fields and laser pulses, offering long coherence times and precise control of quantum states. A recent achievement by QSA researchers at Sandia National Laboratories introduced the “enchilada trap,” a newly designed chip capable of storing up to 200 ions. This device incorporates innovative features such as elevated radiofrequency electrodes and the elimination of dielectric materials beneath them, significantly reducing capacitance and power loss.

China has officially entered the global race to develop advanced brain-computer interface (BCI) technology, becoming the second country in the world to initiate human trials of an invasive BCI system. The breakthrough was reported by state broadcaster CCTV, highlighting a major milestone in the country’s efforts to integrate neuroscience with artificial intelligence and robotics.

The trial involves a 37-year-old man who lost all four limbs in a high-voltage electrical accident over a decade ago. In March, researchers implanted a coin-sized neural interface and flexible electrodes into his brain. Within weeks, he gained the ability to control a computer cursor using thought alone—performing tasks such as playing chess, navigating software, and even gaming with near-normal proficiency.

Sticky compounds found in okra and fenugreek, the same substances responsible for okra’s sliminess and fenugreek’s gel-like texture, may offer a powerful new solution for cleaning polluted water. Scientists have found that natural extracts from these plants can effectively capture and remove microplastics—tiny plastic particles that contaminate oceans, rivers, and even drinking water.

Recent research published in ACS Omega revealed that extracts from okra and fenugreek can eliminate up to 90 percent of microplastics from ocean water, freshwater, and groundwater. The team, led by researcher Rajani Srinivasan, has been focused on developing safe, plant-based approaches to remove pollutants from water systems.

Researchers at MIT, along with collaborators from other institutions, have developed a new fabrication method that integrates high-performance gallium nitride (GaN) transistors onto standard silicon CMOS chips. This breakthrough addresses longstanding challenges related to the high cost and specialized integration requirements of GaN, significantly improving accessibility for a broad range of electronic applications.

Gallium nitride is the second most widely used semiconductor after silicon. Its unique electrical properties make it ideal for applications such as lighting, radar systems, and power electronics. However, to fully harness its capabilities, GaN-based chips must be connected to silicon-based digital chips, commonly known as CMOS chips.

The world’s strangest trampoline doesn’t bounce—it swings sideways and glides around corners. But no one can jump on it, because it’s smaller than the thickness of a human hair.

This miniature trampoline is just 0.2 millimeters wide and incredibly thin—only about 20 millionths of a millimeter thick. Its surface is patterned with regularly spaced, rounded triangular holes, giving it a distinctive perforated look. Despite its delicate appearance, it’s built for endurance. Once set in motion, it barely loses any momentum and can keep swinging for a very long time.
