A new artificial intelligence model developed by researchers at Charité – Universitätsmedizin Berlin could transform how brain tumors are diagnosed, especially in cases where traditional biopsies are risky or impossible. The innovation comes in response to complex cases like that of a patient who first sought medical help for double vision. An MRI revealed a tumor located in a part of the brain that made surgical biopsy highly dangerous.

Confronted with such challenges, the team of researchers turned to an alternative approach. Instead of relying on tissue samples, they developed a method that uses an AI model to analyze the epigenetic fingerprint of tumors—chemical modifications in the genetic material that act like cellular memory and regulate gene activity. These fingerprints can be collected from body fluids such as cerebrospinal fluid, making the process minimally invasive.

In a world increasingly burdened by both plastic waste and carbon emissions, scientists at the University of Edinburgh have developed a breakthrough method that could change how we produce everyday medicines. Instead of relying on crude oil and energy-intensive chemical processes, researchers have found a way to turn plastic waste into paracetamol (also known as acetaminophen)—using nothing more than genetically engineered bacteria.

Traditionally, paracetamol is manufactured from fossil fuel-derived compounds. The production process burns through vast amounts of crude oil, contributing heavily to global carbon emissions. Each year, thousands of tons of fossil fuels are consumed to manufacture medicines like paracetamol, generating significant environmental costs.

In a breakthrough that pushes the boundaries of science fiction into reality, the U.S. military’s Defense Advanced Research Projects Agency (DARPA) has set a new record for wireless energy transmission. As part of its Persistent Optical Wireless Energy Relay (POWER) program, DARPA successfully beamed more than 800 watts of power across a distance of 5.3 miles (8.6 kilometers) using a laser. This achievement not only demonstrates the feasibility of long-distance wireless power but also represents a significant leap forward for both military and civilian energy systems.

The test took place at the U.S. Army’s White Sands Missile Range in New Mexico. During the experiment, a laser was directed through a narrow aperture, reflected off a parabolic mirror, and focused onto a receiver equipped with high-efficiency solar cells. The result was a 30-second energy pulse with an efficiency of approximately 20 percent—impressive given the challenges of atmospheric interference and energy conversion losses over such a long distance. As a playful demonstration of the system’s effectiveness, some of the transmitted power was used to pop popcorn at the receiving end.

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.
