How An Intelligent Thimble Could Replace the Mouse In 3D Virtual Reality Worlds
Humans need better ways to interact with computers in three dimensions. Now computer scientists think they’ve come up with one.
The way in which humans interact with computers has been dominated by the mouse since it was invented in the 1960s by Doug Engelbert. A mouse uses a flat two-dimensional surface as a proxy for a computer screen. Any movements of the mouse over the surface are then translated into movements on the screen. These days, a mouse also has a number of buttons, and often scroll wheel, that allow interaction with on-screen objects.

A Cool New Use For Legos: Growing Lab Plants
Lego plant
Lego walls hold a transparent growth medium mimicking soil. The versatile setup allows researchers to see how plants respond to increasing levels of nutrients, which are here dyed orange.

Legos are great for making all kinds of things–castles, pirate ships and functioning miniature dockyards, as I can tell you from experience. But a new study found that they are absolutely excellent for something unexpected:Â studying the growth of plants and the delicate expansion of their roots.Â
The reasoning of the researchers, from the University of Iowa, went like this: Greenhouses are really large. Micro-fluidic devices used to grow plants and test unique growing conditions are really expensive. So, what about Legos? Transparent blocks of the common toy are perfect for creating the micro-environments needed to study plants and their roots, the researchers wrote in the journal PLOS ONE–they are cheap, abundant, easy to re-arrange, and can be tailor-made with CAD software. The Legos can even be sterilized in an autoclave (basically like a small oven for sanitizing lab equipment) without melting, while remaining translucent.
So far the scientists have used Legos to study and produce images of the real-time growth of the roots of garden cress. The Legos are perfect for holding the see-through growth medium, a type of agar. The Legos have also allowed the researchers to study differences in soil/agar that aren’t easy to produce with larger equipment, and they’re great for building in air pockets, solid barriers between plots, and chemical and microbial gradients that could for example show how roots respond to increasing concentrations of fertilizer.

Facebook used you like a lab rat and you probably don’t care
Companies perform A/B testing — minor site variants to see what users like or don’t like — all the time. Twitter does it with its experimental features, and sites like ours tweak designs for a sample of users to see which ones they prefer. In…

Kudoso’s router tech rewards kids with internet time for doing chores
It’s easy to spend an inordinate amount of time on the internet, and understandably parents would rather their children didn’t grow up permanently glued to a screen. Stripping their hands of tablets and computers is one way to impose down-time…
