Bright, iridescent colors observed in nature are often caused by light interference within nanoscale periodic lattices, inspiring numerous strategies for coloration devoid of inorganic pigments. Here, we describe and characterize the septum of the Lunaria annua plant that generates large (multicentimeter), freestanding iridescent sheets, with distinctive silvery-white reflective appearance. This originates from the thin-film assembly of cellulose fibers in the cells of the septum that induce thin-film interference–like colors at the microscale, thus accounting for the structure’s overall silvery-white reflectance at the macroscale. These cells further assemble into two thin layers, resulting in a mechanically robust, iridescent septum, which is also significantly light due to its high air porosity (70%) arising from the cells’ hollow-core structure. This combination of hierarchical structure comprising mechanical and optical function can inspire technological classes of devices and interfaces based on robust, light, and spectrally responsive natural substrates.

Structural color has captured the fascination of optical researchers through numerous observations throughout history, both in naturally occurring structures and in the animal world (1–3). Plants have also evolved structural colors to fulfill a variety of functions (4–7): Structurally colored leaves (8–10), flowers (11, 12), and fruits (4, 5, 13, 14) are used by plants to regulate light harvesting (8, 15–17) and attract pollinators (6, 7), while they are also believed to promote seed dispersal (4, 5). The few, so far, described plants whose fruits are structurally colored are understory species living in tropical regions, whose fruits reflect light spanning from deep metallic blue to green when ripe.

Korolev crater on Mars—the largest ice skating rink in the solar system, basically—has never looked more enthralling than it does in this impressive new visualization.

The SLS is finally starting take shape.

She can’t get sick or be late to the set, and her hair and makeup needs are minimal: Her name is Erica, and Hollywood is hoping that a sophisticated robot can be its next big star. The synthetic actor has been cast in “b,” a $70 million science-fiction movie which producer Sam Khoze describes as “a James Bond meets Mission Impossible story with heart.”

Scribe Tarek Zohdy (“1st Born”), says, the story is about scientists who create an AI robot named Erica who quickly realize the danger of this top-secret program that is trying to perfect a human through a non-human form.

Variety caught up with the filmmakers Zohdy and Khoze to discuss “b” the $70 million film that plans to finish shooting next year, after a director and human star have been brought on.

A team of researchers from the Technion – Israel Institute of Technology has observed branched flow of light for the very first time. The findings are published in Nature and are featured on the cover of the July 2, 2020 issue.

The study was carried out by Ph.D. student Anatoly (Tolik) Patsyk, in collaboration with Miguel A. Bandres, who was a postdoctoral fellow at Technion when the project started and is now an Assistant Professor at CREOL, College of Optics and Photonics, University of Central Florida. The research was led by Technion President Professor Uri Sivan and Distinguished Professor Mordechai (Moti) Segev of the Technion’s Physics and Electrical Engineering Faculties, the Solid State Institute, and the Russell Berrie Nanotechnology Institute.

Originally intended to make the record attempt this month, plans for the (hopefully) record-breaking run have now been delayed until next year. There seems to be a lot of electric vehicle world record attempts being delayed lately.

But that’s no matter to the Voxan team, including six-time motorcycle racing world champion Max Biaggi, who plans to ride into the record books on the Salar de Uyuni salt flat in Bolivia in July 2021.

The delay may have prevented the team from making their record run this month, but it hasn’t stopped them from unveiling the impressive bike today.

The service still plans to hold an open competition to formally decide on what engine will power the bulk of the jets.

Solar energy researchers at Oregon State University are shining their scientific spotlight on materials with a crystal structure discovered nearly two centuries ago.

Not all materials with the structure, known as perovskites, are semiconductors. But perovskites based on a metal and a halogen are, and they hold tremendous potential as photovoltaic cells that could be much less expensive to make than the silicon-based cells that have owned the market since its inception in the 1950s.

Enough potential, researchers say, to perhaps someday carve significantly into fossil fuels’ share of the energy sector.

Construction is complete on Beijing’s new mega-airport. This is what it looks like.
