It's not rocket science. Oh wait, it is
This week, Reactions is blasting off with an episode that's all about rockets. Featuring Doane College Postdoctoral Fellow Raychelle Burks, Ph.D., we examine the chemistry of solid and liquid propellants, orbital maneuvering and the 'ride-able explosion' that is a rocket launch.
Unique images bring fossil insects back to life
A groundbreaking new book that brings together two of the major disciplines behind 'Jurassic Park' is aiming to raise the profile of insect fossils through stunning photographs and unique illustrations.
Why do dogs smell each other's behinds? Chemical communication explained (video)
Here at Reactions, we ask the tough questions to get to the bottom of the biggest scientific quandaries. In that spirit, this week's video explains why dogs sniff each other's butts. It's a somewhat silly question with a surprisingly complex answer. This behavior is just one of many interesting forms of chemical communication in the animal kingdom.

Smarter than a first-grader?
In Aesop's fable about the crow and the pitcher, a thirsty bird happens upon a vessel of water, but when he tries to drink from it, he finds the water level out of his reach. Not strong enough to knock over the pitcher, the bird drops pebbles into it -- one at a time -- until the water level rises enough for him to drink his fill.

The 92 percent clean plate club
If you're a member of the Clean Plate Club -- you eat pretty much everything you put on your plate -- you're not alone! A new Cornell University study shows that the average adult eats 92 percent of whatever he or she puts on his or her plate. 'If you put it on your plate, it's going into your stomach,' says Brian Wansink Ph.D., author of the forthcoming book, 'Slim by Design,' professor of marketing and director of the Cornell Food and Brand Lab.

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.
