Brain & Behavior
What does the human brain have in common with a popular video game and a carnivorous flower? At least one thing, it turns out. A team from Israel's Weizmann Institute of Science and France's Pasteur Institute found that proteins called glutamate receptors, which enable brain cells to absorb glutamate, a chemical vital for memory and learning, are strikingly similar in shape to both Pacman and the Venus flytrap.  
The Watery Birth of Stars

The Watery Birth of Stars

01.02.1997
Logically, stars should not exist. They are born when clouds of interstellar gas collapse inwardly under their own weight, growing denser and hotter until nuclear fusion causes them to emit energy in the form of light. However, since heat forces matter to expand, this hot contracting gas could be expected to immediately move outward again, preventing star formation from ever reaching completion.

Materials Science
From pens to pans, from hard disks to compact discs, an increasing number of products are made of polymers, giant complex molecules with repeating structural units. Different polymers are often mixed together in liquid form and then allowed to harden in order to impart the best properties of each to the final product. During the mixing, certain types of polymers are more likely than others to move to the surface, forming a coating that thickens with time.
