طور باحثون في جامعة مونستر تقنية جديدة تستخدم الضوء لإنتاج جزيئات "هوسين" شديدة الإجهاد، حيث يمكن لهذه الهياكل المدمجة أن تدعم التطورات في مجالات تطوير الأدوية وعلوم المواد.
قدم فريق بحثي بقيادة البروفيسور فرانك جلوريوس في معهد الكيمياء العضوية بجامعة مونستر في ألمانيا هذه الطريقة، التي تعمل على تحويل هيدروكربونات بسيطة تُعرف باسم 1,4-دايين إلى "هوسين" من خلال التحفيز الضوئي، الذي يوفر الطاقة اللازمة لهذا التحول.

Researchers at ETH Zurich have engineered a catalyst using isolated indium atoms on hafnium oxide to convert CO2 and hydrogen into methanol more efficiently than previous methods. This single-atom design maximizes metal use and enables clearer study of reaction mechanisms. The breakthrough could support sustainable chemical production if powered by renewables.
Researchers at the University of Santiago de Compostela report a light-driven method that directly “allylates” methane—adding an allyl group that can be used to build more complex molecules—and they demonstrate the approach by producing the nonsteroidal estrogen dimestrol from methane.

Researchers at the University of Adelaide have devised a solar-powered process to transform plastic waste into clean hydrogen fuel and other chemicals. The technique, known as solar-driven photoreforming, uses sunlight and photocatalysts to break down plastics at low temperatures. Early experiments show promising hydrogen yields and system stability.
Researchers have developed minuscule devices that use light to control movement in multiple directions, advancing the potential for light-powered spacecraft. The metajets, made from silicon, were tested in a lab setting and showed promising results for steering large sails through space. This breakthrough could help overcome current limitations in directing such vessels over vast distances.

Scientists at EPFL have developed a technique called optovolution, using light to evolve proteins that switch states, sense environments, and perform computations. By engineering yeast cells to survive only if proteins behave dynamically, the method selects optimal variants rapidly. The approach, published in Cell, advances synthetic biology and optogenetics.
