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...

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.

The Bee-Zed asteroid orbits in the opposite direction to planets http://ift.tt/2segX0E IMAGE:  Co-orbital bodies that orbit the Sun in the same direction as a planet can follow trajectories (blue curves with arrows) that, from the perspective of the planet, look like tadpoles,... view more  Credit: Helena Morais & Fathi Namouni In our solar system, an asteroid orbits the Sun in the opposite direction to the planets. Asteroid 2015 BZ509, also known as Bee-Zed, takes 12 years to make one complete orbit around the Sun. This is the same orbital period as that of Jupiter, which shares its orbit but moves in the opposite direction to the planet's motion. The asteroid with the retrograde co-orbit was identified by Helena Morais, a professor at São Paulo State University's Institute of Geosciences & Exact Sciences (IGCE-UNESP). Morais had predicted the discovery two years earlier, so much so that the article describing observations of the asteroid published in Nature...
