Strong, tough, sticky, elastic and biodegradable, silk may be used for a mesh to support injured tissues, or as a temporary container for drugs, stem cells and growth factors. As scientists divine the secret of how spiders and silkworms make silk, they are finding ways to engineer silk into medical devices.

Adding nanotubes makes a stronger plastic, but adding several nano-structures greatly increases the benefit, according to a new study from India. Read about the frontier of material science.

Biology operates on the nanometer scale, and now ultra-small technology is producing monster benefits for genetic analysis, cell biologists, and the treatment of blinding glaucoma.

We need elements. Without phosphorus fertilizer, millions would starve. A shortage of copper means a shortage of electricity. And we’re importing more than 95% of the “rare-earth” elements needed for LCDs, cell phones and green energy. Is this smart?

Lasers read and write CDs and DVDs, form the heart of fiber-optics, and are being used in climate prediction, chemical identification, high-tech manufacturing, even the battle against influenza.

What you can’t see can still interest you. Archeologists use radar, magnetic, electrical gizmos to see through the ground, find places to dig.

New snowflake generator reveals nature’s design principles; anti-reflective coating is nearly perfect, and so is mother-of-pearl inside an abalone. Dive into the nitty gritty of the itty bitty!

The Spallation Neutron Source, a mammoth science project involving the collaboration of six national laboratories, is scheduled to be completed 2006.

Austrian researchers show quantum entanglement across the Danube River, providing new promise in cryptography and computing. At the smallest scale, you can throw out the usual rules of engagement. What’s up with spooky action at a distance?

New technology in ground-based telescopes will give better picture of the universe and detect deadly asteroids.
