Floating displays you can reach into and manipulate, like the ones Tony Stark uses to design his super suits in the Iron Man movies, are one step closer to reality. A new device renders 3-D graphics that users can grab, drag and rotate. Such interactive visuals — which can be seen without a VR headset — could help create new hands-on educational tools or museum exhibits. They might also be used to make 3-D artwork or video games.

cell: (in biology) The smallest structural and functional unit of an organism. Typically too small to see with the unaided eye, it consists of a watery fluid surrounded by a membrane or wall. Depending on their size, animals are made of anywhere from thousands to trillions of cells. Most organisms, such as yeasts, molds, bacteria and some algae, are composed of only one cell. circuit: A network that transmits electrical signals.

Arctic: A region that falls within the Arctic Circle. The edge of that circle is defined as the northernmost point at which the sun is visible on the northern winter solstice and the southernmost point at which the midnight sun can be seen on the northern summer solstice. The high Arctic is that most northerly third of this region. It’s a region dominated by snow cover much of the year. climate: The weather conditions that typically exist in one area, in general, or over a long period.

The foul stench of penguin poop sets Antarctic krill on edge. In lab experiments, the mere scent of penguin droppings — or guano — sent krill scrambling for escape, researchers report March 20 in Frontiers in Marine Science. The stink also seemed to suppress krill’s appetites. Antarctic krill (Euphausia superba) form a cornerstone of the Southern Ocean ecosystem.

ash: (in geology) Small, lightweight fragments of rock and glass spewed by volcanic eruptions. atom: The basic unit of a chemical element. Atoms are made up of a dense nucleus that contains positively charged protons and uncharged neutrons. The nucleus is orbited by a cloud of negatively charged electrons. cloud: A plume of molecules or particles, such as water droplets, that move under the action of an outside force, such as wind, radiation or water currents.
