How to Create a Moss Terrarium for a Fraction of the Cost of Those Fancy Kits http://ift.tt/2t0Fh3c For my moss terrarium, I combined two of my favorite things: Gnomes and gingers. Photo by Olga Oksman/Lifehacker. Terrariums are having their biggest moment since Queen Victoria was in power. A popular way to exhibit plants in the late 1800s, terrariums, called “Wardian Cases” in the Victorian era, were elaborate affairs that could take up an entire side table. These days, the smaller, simpler iterations line the windows of trendy shops, show up on gift guides and, here in Brooklyn, even inspired a terrarium-only shop called Twigs. A tiny green universe enclosed neatly in glass, easy to care for and often populated by delightful miniatures, it is easy to see why terrariums, especially the easier-to-keep-alive moss variety, are back in vogue. They make a great alternative to a sad desk cactus at work, requiring little light and care. And if you should neglect them completely, the...

The Age of Electric Aviation Is Just 30 Years Away

The Age of Electric Aviation Is Just 30 Years Away http://ift.tt/2rof7bO Every vision of the future of flight involves electric aircraft—air taxis hopping from one skyscraper to the next as airliners cruise silently over oceans. After all, what kind of future traveler would rely upon fossil fuels? One who wants to go anywhere. For all the hype electric aviation gets, the concepts put forth by aerospace companies and startups are just this side of impossible. Flying requires extraordinary amounts of energy, and doing so under electric power requires at least one massive leap forward in battery tech. Or, as aviation expert Richard Aboulafia puts it when reviewing yet another flying car idea: “Insert miracle.” The problem is, batteries simply do not offer the power-to-weight ratio or cost needed to be feasible, and will not for some time. The technological advancements that allowed Tesla to squeeze 335 miles from the Model S and Chevrolet to get 200 out of the Bolt are not enoug...

A material inspired by a sea worm changes according to the environment

A material inspired by a sea worm changes according to the environment http://ift.tt/2pbChAN The gelatinous jaw of a sea worm, which becomes hard or flexible depending on the environment around it, has inspired researchers at the Massachusetts Institute of Technology to develop a new material that can be applied to soft robotics. Despite having the texture of a gel, this compound is endowed with great mechanical resistance and consistency, and is able to adapt to changing environments.
