Is it time for Congress to act?
As the issue of an open and free internet again comes up for public debate, Congress could participate – and help regulators devise a workable set of policies.
There are a lot more holes in cybersecurity fences.

Colleen Burge counts oysters on an oyster aquaculture lease in California.
Oysters grow in seawater and filter their food from it, so how do you shield them from waterborne diseases? Scientists are working to develop strains that are resistant to a fast-spreading herpes virus.
Robots can also lend a hand of sorts.
Robots have the potential to help support a growing population that wants to age in their own homes. But those helpful machines won't be the humanoid butlers of science fiction.
Color-changing cells in an Atlantic squid’s skin contain light-sensitive pigments.
We're used to thinking of our eyes detecting light as the foundation of our visual system. But what's going on in other cells throughout the body that can detect light, too?
Realistic and stylized at the same time.
As the animated film 'Bambi' celebrates its 75th anniversary, a reminder that humans often try to express reality. But once they do, they go back to making art.

Math instruction is stuck in the last century. How can we change teaching methods to move past rote memorization and help students develop a more meaningful understanding – and be better at math?
Polysaccharide molecules such as cellulose, seen here, are long chains of sugars that are very hard to break apart. Enzymes – proteins that can degrade polysaccharides – have many industrial uses.
Bio-prospecting is the search for useful materials from natural sources. A biologist explains what we can learn from bacteria about breaking down plant material, and how we can use that knowledge.
Ingredients from shampoo, sunscreens and other personal care products are turning up in water supplies. Some are toxic or cause hormonal damage to aquatic life, and could threaten human health.
