How children categorize living things
'Name everything you can think of that is alive.' How would a child respond to this question? Would his or her list be full of relatives, animals from movies and books, or perhaps neighborhood pets? Would the poppies blooming on the front steps make the list or the oak tree towering over the backyard? The children's responses revealed clear convergences among distinct communities but also illuminated differences among them.

Fair cake cutting gets its own algorithm
Mathematician Julius Barbanel of Union College, and political scientist Steven Brams of New York University, both in the US, published an algorithm in Springer's The Mathematical Intelligencer by which they show how to optimally share cake between two people efficiently, in equal pieces and in such a way that no one feels robbed.

Brain of world's first known predators discovered
Scientists have found the fossilized remains of the brain of the world's earliest known predators, from a time when life teemed in the oceans but had not yet colonized the land. The discovery reveals a brain much simpler than those known in some of the animal's prey and helps answer questions surrounding the evolution of arthropods.

Go play outside! Outdoor time promotes physical activity in youth
The World Health Organization recommends that youth participate in a minimum of 60 minutes of moderate to vigorous physical activity (MVPA) each day. Studies have shown that youth experience most of their MVPA during school hours. Therefore, it stands to reason that increasing outdoor time after school hours would increase MVPA. In a new study scheduled for publication in the Journal of Pediatrics, researchers confirmed that time spent outdoors after school was positively associated with MVPA.

Rotten egg gas holds key to healthcare therapies
It may smell of flatulence and have a reputation for being highly toxic, but when used in the right tiny dosage, hydrogen sulfide is now being being found to offer potential health benefits in a range of issues, from diabetes to stroke, heart attacks and dementia.

Laboratory models suggest that stretching forces shaped Jupiter moon's surface
Processes that shaped the ridges and troughs on the surface of Jupiter's icy moon Ganymede are likely similar to tectonic processes seen on Earth, according to a team of researchers led by Southwest Research Institute. To arrive at this conclusion, the team subjected physical models made of clay to stretching forces that simulate tectonic action. The results were published in Geophysical Research Letters.
World Cup chemistry: The science behind the 'brazuca' (video)
The World Cup final is almost here, and no matter which two teams meet for the title match, there's one thing they'll both need to win: the ball. This week, Reactions examines the chemistry that goes into making the 'brazuca,' and what makes it different from most other soccer balls out there. The video is available at https://www.youtube.com/watch?v=1XNTfslUzt8.
The chemistry of fireworks: Fourth of July science (video)
The Fourth of July is just days away, and that means millions of Americans will soon enjoy eye-popping fireworks displays around the country. These dazzling light shows are actually carefully crafted chemical reactions. This week's Reactions episode features John Conkling, Ph.D., the professor who literally wrote the book on pyrotechnics. In the video, Conkling explains the chemistry that creates those amazing fireworks displays.
Stanford's Precourt Institute partners with KQED on a new e-book series on energy
The Precourt Institute for Energy and KQED, public media for Northern California, have created a free, two-part e-book series on energy for iPads and Mac computers primarily targeted at grades eight to 13. The interactive e-books and companion curriculum give readers a broad introduction to energy.

Picture books for visually impaired kids go 3-D thanks to CU-Boulder research team
A children's classic that already is a candidate for the all-time best feel-good book, 'Goodnight Moon,' has gotten a boost: A University of Colorado Boulder team printed the first 3D version of it, allowing visually impaired children and their families to touch objects in the story -- like the cow jumping over the moon -- as it is read aloud.
