Turning tough plant materials into usable fuel has long been one of the biggest challenges in renewable energy. At the center of this effort is cellulose, Earth’s most abundant renewable polymer. Despite being made entirely of glucose, its tightly packed crystalline structure—combined with lignin and hemicellulose—makes it extremely difficult to break down. Nature accomplishes this only slowly, and with the help of complex enzyme systems.

Now, scientists at the Brazilian Center for Research in Energy and Materials (CNPEM), along with collaborators in Brazil and abroad, have discovered a powerful new enzyme that can unlock cellulose more efficiently than ever before. Known as CelOCE (cellulose oxidative cleaving enzyme), this metalloenzyme could dramatically enhance the production of second-generation ethanol, a clean fuel made from agricultural waste such as sugarcane bagasse and corn straw. The research was recently published in Nature.

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.
