German automotive supplier Continental has introduced a revolutionary sensor technology designed to measure temperature directly on the rotor of permanently excited synchronous motors (PMSMs)—a first in the electric vehicle (EV) industry. The innovation, known as the e-Motor Rotor Temperature Sensor (eRTS), is poised to make electric motors more powerful, cost-effective, and environmentally sustainable.

This advancement marks a significant leap forward in EV motor technology. Unlike current systems that estimate rotor temperature through indirect methods like stator sensors, current flow, and environmental data, the eRTS provides direct, real-time temperature readings on the rotor itself. This dramatically reduces the tolerance range from 15°C (59°F) to just 3°C (37.4°F), allowing for far greater accuracy and efficiency in motor design and operation.

Swiss biotech company TissueLabs has announced the launch of its most advanced bioprinter to date, the TissuePro. Designed specifically for tissue engineering and regenerative medicine, TissuePro introduces a significant leap forward in multi-material precision printing, automation, and versatility, surpassing the capabilities of the company’s earlier models.

TissuePro is the successor to TissueStart, TissueLabs’ entry-level bioprinter, which is currently used in over 300 laboratories across more than 30 countries. While TissueStart served as an accessible platform for researchers beginning their bioprinting journey, TissuePro is built for scaling up operations and tackling more sophisticated applications. These include complex tissue constructs, organ-on-a-chip systems, vascularized structures, and other frontier challenges in regenerative medicine.

MIT researchers have developed an innovative membrane that can separate components of crude oil by molecular size, potentially replacing the energy-intensive process of distillation. This advancement could significantly reduce the energy consumption and environmental impact associated with refining oil into fuels such as gasoline, diesel, and heating oil. Currently, refining processes rely on heating crude oil to high temperatures to separate its components based on their boiling points, a method that accounts for approximately 6% of global carbon dioxide emissions. The new membrane offers an alternative by filtering molecules according to size and shape, eliminating the need for boiling.

According to Zachary P. Smith, associate professor of chemical engineering at MIT and senior author of the study, the new method represents a transformative approach to separation technology. Instead of relying on thermal energy, the membrane uses molecular sieving to isolate specific components from crude oil. The membrane is a thin film that resists swelling—a common issue with previous membranes—and can be manufactured using interfacial polymerization, a technique already common in industrial settings. This makes the technology not only effective but also scalable.

Researchers have finally cracked a long-standing mystery in nanoscience by uncovering a bizarre quantum interaction between carbyne—an exotic carbon chain—and carbon nanotubes. This breakthrough resolves an unexplained vibrational phenomenon that had puzzled scientists for nearly a decade.

The international study, led by the University of Vienna in Austria and supported by collaborators from Italy, France, China, and Japan, offers new insight into the quantum behavior of carbon-based nanostructures. Specifically, the team explored how carbynes—linear chains of carbon atoms linked by alternating single and triple bonds—interact with carbon nanotubes on a fundamental quantum level.

Scientists in Germany have developed a groundbreaking smart façade system that dynamically changes shape in response to weather conditions, paving the way for a new generation of energy-efficient, adaptive building technologies.

Called FlectoLine, this innovative 83.5-square-meter (898-square-foot) façade adapts in real time to environmental changes to optimize indoor comfort and minimize energy use. The system was recently awarded the Special Prize by the MVV Foundation for the Future at the inaugural Award for Bio-Inspired Innovations Baden-Württemberg—a testament to its visionary design, which blends engineering with lessons from nature.

Researchers at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have developed a revolutionary solid-state thermoelectric refrigeration technology that significantly outperforms current systems. Using nano-engineered materials called Controlled Hierarchically Engineered Superlattice Structures (CHESS), the team has achieved twice the efficiency of traditional bulk thermoelectric materials—offering a scalable, energy-efficient alternative to conventional compressor-based cooling systems.

As the global demand for compact, reliable, and eco-friendly refrigeration solutions increases—driven by population growth, urbanization, and expanding digital infrastructure—this advancement could redefine the cooling industry.

Researchers at the University of Tokyo have achieved a significant breakthrough in sustainable chemistry by developing a method to synthesize ammonia using only sunlight, atmospheric nitrogen, and water. This innovative process mimics the natural nitrogen-fixation methods employed by cyanobacteria in symbiotic relationships with plants. According to a university press release, this development opens the door to ammonia production with dramatically lower energy requirements and environmental impact.

Ammonia is a cornerstone of global agriculture, primarily used in the production of urea-based fertilizers essential for large-scale crop cultivation. With approximately 200 million tonnes of ammonia produced annually—over 80 percent of which is used in agriculture—finding a cleaner production method is critical. Currently, ammonia is synthesized through the Haber-Bosch process, which requires high temperatures and pressures, making it energy-intensive and responsible for about 2% of global carbon emissions.

The ZEUS laser facility at the University of Michigan has officially entered the record books, firing its first-ever 2-petawatt pulse—making it the most powerful laser in the United States. This staggering burst of energy, equal to twice the peak power of any other laser in the country, lasts a fleeting 25 quintillionths of a second (25 femtoseconds), but its implications could be long-lasting and transformative across numerous scientific fields.

“This milestone marks the dawn of a new era for American high-field science,” said Karl Krushelnick, director of the Gérard Mourou Center for Ultrafast Optical Science, which houses ZEUS. Designed to probe the most extreme conditions in nature, the laser is poised to fuel breakthroughs in astrophysics, quantum physics, national defense, and medical technologies.

In a groundbreaking achievement, Korean researchers have successfully produced eco-friendly solar hydrogen using an ultrasmall quantum semiconductor nanocluster—marking the first time in history this has been accomplished. This novel material, comprised of just 26 atoms, is now considered the smallest inorganic semiconductor ever used as a photocatalyst.

The research was conducted through a collaboration between Daegu Gyeongbuk Institute of Science and Technology (DGIST), Hanyang University, and Korea University. The team utilized a cadmium selenide ((CdSe)₁₃) nanocluster, measuring less than one nanometer, to drive hydrogen production from water under sunlight. As part of the II-VI group semiconductors, cadmium selenide is known for its high reactivity but has long faced challenges due to its instability and poor conductivity—issues that this team has now addressed.

Sound isn’t just for music or communication — it’s becoming a tool for precision manipulation in underwater environments. Researchers have developed a novel metamaterial that allows objects to be moved, rotated, and positioned underwater without any physical contact, using only carefully controlled sound waves.

This breakthrough comes from Dajun Zhang, a doctoral student at the University of Wisconsin-Madison. He presented his findings on May 20 at the 188th Meeting of the Acoustical Society of America and the 25th International Congress on Acoustics.

Wearable technology is undergoing a transformation — and this time, it’s not driven by electronics. Researchers at ETH Zurich have developed a new class of smart textiles that rely on sound waves rather than wires and sensors to monitor motion, touch, and even breathing. Their groundbreaking innovation, called SonoTextiles, turns everyday fabrics into responsive, data-collecting tools through the use of acoustic waves transmitted via glass fibers.

The research team, led by Professor Daniel Ahmed, has successfully integrated glass microfibers into fabric to create garments capable of sensing movement and pressure. Each glass fiber acts as a sensor: a tiny transmitter sends ultrasonic sound waves (around 100 kHz) down the fiber, while a receiver on the opposite end measures any changes in those waves.

A new recycling technique developed at the University of Leicester uses sound waves to efficiently separate materials in fuel cells, offering a cleaner and faster method to recover valuable components and prevent environmental contamination.

The method specifically targets catalyst-coated membranes (CCMs), which are used in hydrogen-powered technologies like fuel cells and water electrolyzers. These membranes typically combine precious platinum group metals with fluorinated polymer membranes, known as PFAS — substances that pose serious environmental and health risks due to their persistence in ecosystems.
