China’s maglev research program has reached a major milestone by accelerating a 1.1-tonne test vehicle to 650 km/h (about 404 mph) in just seven seconds, all within a 600-meter stretch of track. The achievement took place at Donghu Laboratory in Hubei Province, where engineers are developing short-distance, high-speed test methods that depart from the traditional long test tracks typically used for such experiments.

Instead of relying on multi-kilometer tracks to test acceleration and braking, the Donghu team implemented a compact 1-km demonstration line. The system uses electromagnetic propulsion, with a high-power linear motor paired with magnetic levitation that keeps the vehicle hovering just above the guideway. With no physical contact between the vehicle and the track, the system only contends with aerodynamic drag, allowing for rapid acceleration and precise braking.

Researchers at MIT Lincoln Laboratory have unveiled a groundbreaking method for 3D printing glass that dramatically reduces the heat typically required for glass production. This innovative process enables the creation of complex glass structures at room temperature, using a technique known as direct ink writing, and requires curing at only 250°C—far below the 1,000°C or more usually needed in traditional glassmaking.

Using this low-temperature additive manufacturing method, researchers successfully fabricated glass cups with tailored optical properties. These properties can be customized by modifying the chemical composition of the specially formulated inks used during printing. The inks are composed of inorganic particles suspended in a silicate-based solution, which gives engineers control over the final material’s optical, electrical, and chemical characteristics.

A team of chemists from the University of Michigan, University of California, Davis, and University of California, Los Angeles has developed a novel method to capture carbon dioxide and convert it into metal oxalates—solid compounds that can serve as precursors for cement production. This breakthrough offers a promising route to reduce industrial carbon emissions and repurpose CO₂ into valuable materials.

Led by Charles McCrory, associate professor of chemistry and macromolecular science and engineering at the University of Michigan, the research is part of the Center for Closing the Carbon Cycle (4C), an Energy Frontier Research Center. The 4C initiative, directed by Jenny Yang at UC Irvine, focuses on developing methods to transform captured carbon dioxide into usable fuels and products.

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.
