Microrobot technology: Externally connecting in vivo neural networks

Researchers have developed a technology for delivering a microrobot to a target point of a hippocampus in an in-vitro environment, connecting neural networks, and measuring neural signals. The findings are expected to contribute to neural network research and the verification and analysis of cell therapy products.

Scallop eyes as inspiration for new microscope objectives

Neuroscientists have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one hand and the eyes of scallops on the other. The new objectives enable high-resolution imaging of tissues and organs in a much wider variety of immersion media than with conventional microscope lenses.

Why are forests turning brown in summer?

European forests are increasingly turning brown in the course of hot, dry summers. In the scorching summer of 2022, Europe experienced more trees turning brown than ever, with 37% of temperate and Mediterranean forest regions affected. In the three-year meteorological history of low-?greenness events, characteristic weather signals can be found as precursors of the events.

Researchers elucidate the complexity of flames

A research team, led by Professor Yuji Nakamura of the Department of Mechanical Engineering at Toyohashi University of Technology, discovered that the flickering of flames can be freely controlled by moving two flames closer together or further apart. Until now, it had been known that interference between flames separated by a certain distance causes the flames to flicker during in-phase or...

Imaging technique reveals electronic charges with single-atom resolution

Materials typically conduct electricity or insulate against it—so experimental and theoretical physicists have been captivated by a compound called samarium hexaboride (SmB6) that appears to do both. Numerous studies over the course of 50 years have revealed that SmB6 acts like an insulator as well as an electricity-conducting metal.

Researchers synthesize graphene using intense light

DGIST Professor Yoonkyu Lee's research team used intense light on the surface of a copper wire to synthesize graphene, thereby increasing the production rate and lowering the production cost of the high-quality transparent-flexible electrode materials and consequently enabling its mass production. The results were published in the February 23 issue of Nano Energy.

Research finds that cKMT1 methylates FNR and regulates energy transfer in cyanobacteria

Cyanobacteria are a diverse group of prokaryotes and the only prokaryotes capable of oxygenic photosynthesis. They exist in a variety of environments and play crucial roles in the global carbon and nitrogen cycles. Synechocystis sp. PCC 6803 (Synechocystis) has been used extensively as a model cyanobacterium for studies concerned with photosynthesis and environmental adaptation.
