The microalga Nannochloropsis oceanica holds potential as a valuable source of sustainably produced nutrients such as protein, omega-3 fatty acids, and vitamin K2. A new study from DTU shows that cultivation conditions, particularly temperature and light, play a significant role in the yield.

A research group at Umeå University has developed new advanced light-controlled tools that enable precise control of proteins in real time in living cells. This groundbreaking research opens doors to new methods for studying complex processes in cells and could pave the way for significant advances in medicine and synthetic biology.

The electronics of the future can be made even smaller and more efficient by getting more memory cells to fit in less space. One way to achieve this is by adding the noble gas xenon when manufacturing digital memories. This has been demonstrated by researchers at Linköping University, Sweden, in a study published in Nature Communications. This technology enables a more even material coating even in small cavities. 

By using optically active liquid crystals as reaction sites, researchers at University of Tsukuba have successfully achieved the living polymerization of polymers with aligned helical structures. In this process, optically inactive monomers adopt the chiral (mirror-image) structure in liquid crystals as they grow, resulting in optically active polymers. This breakthrough represents a pioneering achievement in both asymmetric chemistry and polymer chemistry.

NIST scientists have developed a new method for measuring temperature extremely accurately by using giant “Rydberg” atoms. This atomic thermometer provides accurate measurements “out of the box,” without needing initial factory adjustments, because it relies on the basic principles of quantum physics. By using Rydberg atoms’ sensitivity to environmental changes, this technique could simplify temperature sensing in extreme environments, from space to high-precision industries.

How can the latest technology, such as solar cells, be improved? An international research team led by the University of Göttingen is helping to find answers to questions like this with a new technique. For the first time, the formation of tiny, difficult-to-detect particles – known as dark excitons – can be tracked precisely in time and space. These invisible carriers of energy will play a key role in future solar cells, LEDs and detectors. The results were published in Nature Photonics.

A new strategy for measuring magnetic fields could one day lead to a host of new quantum sensors—from tools that might map out the activity of the human brain to devices that could help airplane pilots navigate the globe.
