Nickel oxide films enhance solar-driven splitting of water

As a society, we have seen a tremendous increase in sustainable technology over the last decade. From recycling, to LEDs, to LEED Certified buildings, and to battery-powered cars, clear progress has been made. Today, scientists continue to push boundaries on sustainable technology, shaping public policy and the future in the process.

One area of active research is sustainable solar-produced fuels. Researchers are developing artificial photosynthetic systems that are designed to replicate the natural process of photosynthesis, which harnesses solar energy to convert water and carbon dioxide into oxygen and sugars. These systems, both natural and synthetic, involve chemically converting water into oxygen gas and hydrogen gas.

Usually, our water-splitting processes rely on electrolysis—running electricity through water to trigger a reaction that splits it. In order to carry out this process using solar energy, systems require stable, light-absorbing electrodes. Unfortunately, the solution conditions required to carryout water electrolysis often cause electrodes to degrade, which has hampered progress toward developing efficient, stable artificial photosynthetic systems.

#NYFW Anna Sui Fall 2015

The Vikings are coming! For fall 2015, fashion designer Anna Sui took inspiration from Nordic culture and interior design. You see contemporary bold prints in the style of Marimekko. You see layered textures of knit, fur, and patterns upon pattern to give the Viking look a contemporary update. Who knew Hagar the Horrible was a fashion icon?

As with every season, that theme was mixed with Sui's bohemian and rock and roll aesthetic. Her signature purple is always there. Her flea market sensibility is always there. While I haven't always liked her collection, this one was a lot of fun with several outfits I would actually want.

Anna Sui for me always embodied the club kid of the 1990s, but like myself, we all had to grow up. Her look maintains the fun sense to please her diehard fans overseas but matured with more versatile pieces for fans that grew with her. She even just launched a home collection for fans who want to live her lifestyle all day and all night. I wonder if that includes a couch shaped like a Viking boat?

DNA map of UK migration history shows Vikings drew the line at pillaging

A fine-grained genetic analysis has created a detailed map of genetic variation across the UK. It gives us a clearer picture of the waves of migration that populated the UK and could also contribute to research on genetic diseases.

Obviously, people in the UK these days don’t always stick around where they were born, so people in a given region don’t necessarily share ancestry. But, if you can find people whose ancestry is closely tied to a particular region, it becomes possible to approximate what genomes would have been like a century ago, before people could move around so easily.

A paper published in Nature this week analyzed the genomes of 2039 people whose grandparents were all born within 80 kilometers (50 miles) of one another. This effectively meant that the researchers were sampling the genomes of the grandparents, whose average birth year was 1885 and who obviously had strong ties to a region. This allowed the researchers to investigate the genetic structure of the UK population before the mass movements of last century.

The Reinvention of Normal: A Fun Profile of Whimsical Inventor and Artist Dominic Wilcox

In this brief profile by filmmaker Liam Saint Pierre, we dive head-first into the strange mind of British artist and inventor Dominic Wilcox who’s been entertaining the world for years with his delightfully impractical ideas. His recent off-the-wall inventions include a stained glass driverless car, shoes with built-in GPS that guide you back home, and a giant listening device called Binaudios that mimic tourist binoculars for the purpose of listening to a city. “Let’s do the ridiculous and by doing the ridiculous something else might come of it,” Wilcox shares in the film, perfectly encapsulating his entire artistic practice. He also just published a book filled with comic-like sketches of his most outlandish ideas, Variations on Normal, which is available on his website. (via It’s Nice That)
