How are the elements that make up life distributed among stars and planets? As trippy as the question seems, astronomers from the Sloan Digital Sky Survey (SDSS) announced at the 229th meeting of the American Astronomical Society that they knew the answers — or, at least, were starting to learn them.

The discovery that extinct marine organisms called trilobites laid eggs provides the first direct evidence for how they reproduced. 

 

Trilobites lived between 520 million and 250 million years ago, and are one of the earliest known groups of arthropods (invertebrates, including modern insects, with exoskeletons and segmented bodies).

 

Thomas Hegna of Western Illinois University in Macomb and his colleagues report the discovery of ancient trilobite eggs in New York State, in rocks about 450 million years old. The eggs are spherical, almost 200 micrometers in diameter, and lie near several well-preserved trilobite fossils.

 

Trilobites may have released eggs and sperm through genital pores at or near the backs of their heads, the authors say.

We saw tons of new stuff at CES this year. But one thing that particularly caught our eye was Kubo, the robot that teaches kids how to code.

Kubo is a pretty simple robot – it’s about the size of a can of soda and has two wheels that allow it to roll around a desk or table. But what it lacks in advanced physical ability it makes up for in brains.

Kubo comes with its own programming language called TagTile. The language consists of puzzle pieces that fit together to give Kubo instructions. For example, you could connect three pieces together – forward, turn, then another forward. Kubo then drives over these pieces oncer to “learn” the command, then can remember and perform it without needing the pieces.

Kubo reads the puzzle pieces using an RFID technology – each piece has an individual embedded RFID tag, and Kubo itself has a reader built in.

While it sounds simple, it’s a pretty good way to teach kids the basics of programming without having them stare at a screen.
