Laser tweezers grab nano bits
An optical fiber, a bit of gold and a laser make up a new type of tweezers. Scientists may soon use it to pick up and move around individual viruses or proteins.

Earthquake-triggered lightning?
An experiment with beads offers support for the claim that a rare type of lightning may accompany some quakes.

Temperature ‘lock’ for new hard drives?
A novel material can alter how easy it is to change data stored on it, based on temperature. One immediate application: more secure hard drives for computing.

We are stardust
Everything making up Earth and what’s now living upon it — from trees and people to our pets and their fleas — owes their origins to the elements forged by ancient stars.

Closing in on fusion energy
Scientists blasted a tiny capsule of hydrogen with laser beams, setting off a reaction that released more energy than in earlier experiments. Still, scientists remain a long way from creating a reaction that releases more energy than it needs to get started.

Building a mirror with light
Scientists proved that lasers can be used to harness materials into a reflective surface. Some scientists ask: Can a space mirror be far away?

The ultimate wordfind puzzle
The world’s oldest library has books with hidden texts. Researchers are now using a high-tech approach to reveal their long-masked words.

Jupiter’s long-lasting storm
Most studies of Jupiter’s centuries-old Great Red Spot suggest this giant storm should have petered out after a few decades. A new study traces the storm’s staying power to the vertical movement of its gases.

Cool Jobs: Data detectives
Statisticians are experts in seeing the patterns hidden within the raw numbers called data. They especially excel at finding real trends, while eliminating what is actually due to chance. That’s why they offer a good reality check in any field that involves numbers.

X-ray ‘eyes’
Movie directors often make “short” subjects, flicks running sometimes just a few minutes or so. But scientists have begun making much quicker “shorts,” essentially nanofilms. Their goal: catching science in action.

Looking unbelievably cool
Everything above absolute zero gives off some heat. Usually objects radiate more heat — or energy — as their temperature climbs. But engineers now have created a material that sometimes appears to cool even as it is warming.

Veggies: A radiation shield
Here’s another reason to eat broccoli and related veggies: They protect the body’s cells from killer radiation — at least in rats.
