Compact flat-lens system can generate nondiffracting bottle beams

Stepping away from its billions-of-years-old role as a genetic blueprint, DNA is now embarking on a new journey as an active field agent within cells. This research by a team led by Professor Jongmin Kim and Ph.D. candidate Geonhu Lee from the Department of Life Sciences at POSTECH (Pohang University of Science and Technology) was published in Nature Chemistry.

Chocolate prices have jumped again this Easter, and it has a lot of people concerned about how much higher they can go—and why they are so high in the first place.

Take a typical fish out of the water and it won't live long. It gets the oxygen it needs from the water it swims in. In a similar way, scientists are exploring dependency as a method of controlling what microbes can do and where they can do it.

Polarization has always been a core property of light that is essential for a broad range of everyday applications, including displays (LED, LCD, 3D Cinematics), photography, as well as satellite and antenna technologies. The ability to tune light polarization empowers us with enhanced communication signals, improved image quality, and access to hidden image details and non-conventional imaging modes (e.g. 3D imaging).
