Researchers at INRS have developed a synthetic photonic lattice capable of generating and manipulating quantum states of light, paving the way for promising advancements in applications ranging from quantum computing to secure quantum communication protocols.
A study co-directed by Professor Roberto Morandotti of Institut national de la recherche scientifique (INRS) in collaboration with teams from Germany, Italy, and Japan paves the way for innovative solutions that could enable the development of a system to process quantum information with both simplicity and power.
Their work, just published in the journal Nature Photonics, presents a method for manipulating the photonic states of light in a never-before-seen way, offering greater control over the evolution of photon propagation. This control makes it possible to improve the detection and number of photon coincidences, as well as the efficiency of the system.
The Expedition 72 crew studied micro-algae and DNA-like nanomaterials on Tuesday to improve health in space and on Earth. The orbital residents also worked on cargo transfers and lab maintenance aboard the International Space Station.
NASA Flight Engineer Nick Hague began his day processing radiation-resistant samples of Arthrospira C micro-algae and stowing them in an incubator for analysis. The samples will be exposed to different light intensities to observe how they affect the micro-algae’s cell growth and oxygen production. Results may advance the development of spacecraft life support systems and fresh food production in space.
Afterward, Hague joined Commander Suni Williams of NASA for a different research session mixing water with samples of messenger RNA, or mRNA, and protein to create DNA-like nanomaterial products inside the Kibo laboratory module’s Life Science Glovebox. Flight Engineer Butch Wilmore then transferred the samples, exposed them to ultrasonic waves, and imaged them with a spectrophotometer to measure the intensity of light at different wavelengths and evaluate the quality of the nanomaterials. The samples will also be returned to Earth for further evaluation. Results may lead to improved therapies for Earth and space health conditions as well as advance the space economy.

Summary: A new AI algorithm inspired by the genome’s ability to compress vast information offers insights into brain function and potential tech applications. Researchers found that this algorithm performs tasks like image recognition and video games almost as effectively as fully trained AI networks.
By mimicking how genomes encode complex behaviors with limited data, the model highlights the evolutionary advantage of efficient information compression. The findings suggest new pathways for developing advanced, lightweight AI systems capable of running on smaller devices like smartphones.

Nano-ZnO is a potential catalyst material for carbon dioxide electrocatalytic reduction (CO2RR), but its effective Faraday efficiency (FE) is still below 90% and the current density is less than 300 mA cm-2, which is not enough to meet industrial requirements.
A new study published in Chem Catalysis reported on ZnO nanorods for electrocatalytic CO2RR, which after 500°C heat-treatment, achieved the highest oxygen vacancy content, the highest FECO of 98.3%, and a partial current density of 786.56 mA cm-2 in a 3 M KCl electrolyte.
The research was conducted by Prof. Wu Zhonghua and Dr. Xing Xueqing from the Institute of High Energy Physics of the Chinese Academy of Sciences (CAS) and Prof. Han Buxing from the Institute of Chemistry of CAS.
This was the first time ULA’s Vulcan rocket was eligible to compete for a major NASA contract.
