A beaver buddy for the dinosaurs?
Wouldn't it be cool to go back in time and see what things looked like 164 million years ago? Those were the days of the dinosaurs, which is why scientists digging in China were so surprised when they found a new animal fossil from that time that looks a lot like a beaver!

For tomatoes, yummy means healthy
Can a tomato taste healthy? That's what some scientists think. They wonder if maybe the flavors of a tomato or a strawberry give us little clues about the vitamins and other healthy stuff inside, according to a study in the 10 February issue of the journal Science.

Find far fish fast
In May of 2003, scientists recorded tens of millions of fish swimming around in one loosely connected group in the Atlantic Ocean not so far from New York City. That's a lot of fish to keep track of at the same time. In fact, that's the most fish, and maybe the most creatures that have ever been instantaneously "caught on film."

Tracking cougars with a virus bug
What if your mom could tell where you'd been and who you'd been hanging out with after school, just by checking to see who else in your neighborhood also had the nasty cold you caught last week? That's the kind of snooping some scientists did recently when they wanted to know where cougars were living and roaming around in the western United States and Canada.

'Gut feeling' geometry
Kids and adults who have probably never seen a ruler or talked about triangles, rectangles or parallel lines have a reliable "gut feeling" about geometry, according to a new study.

It's raining natural gas
On Saturn's biggest moon, infrequent but heavy downpours of liquid natural gas have created steep-sided valleys and flushed icy debris and dark goo into shallow lakes.

Farming ants run microbe motels
The ants that grow fungus in little gardens face a problem that is well known to human farmers – pests. Scientists have just discovered that farming ants are covered in little "motel rooms" that serve as shelter for bacteria that protect their crops.

Water in the trunk of a tree
Every December, people cut down pine trees and other evergreens and stick them in their houses. The trees start sucking up water right away (unless you wait too long between cutting the tree and putting it in water, of course). A new study helps to explain how the heck water moves up the trunk of cone-making trees called "conifers."

Zebrafish, tiny aquarium fish with stripes on their sides, have helped scientists explain – in terms of genetic makeup – the variety of colors that human skin comes in.

When did 'pet rocks' and 'wild rocks' become cool?
"Pet rocks" became cool in 1975 -- they suddenly seemed like the perfect low-maintenance pet, and almost instantly, people were buying pet rocks like crazy. You could teach a pet rock to sit and play dead instantly!

Earliest bird had dino-like feet
A new fossil discovery shows that the earliest birds had feet similar to those of theropod dinosaurs (the group of two-legged, meat-eating dinosaurs that includes T. rex). The new specimen provides important details about the feet and skull of these birds and strengthens the argument -- which many but not all scientists agree on -- that modern birds arose from theropod dinosaurs.

New 'time machine' from ice
Thanks to air bubbles trapped in a long cylinder of ice from a glacier in Antarctica, scientists have jumped an extra 210,000 years back in time. This scientific "time machine" now tells us how much carbon dioxide and methane was in the air as far back as 650,000 years ago.

What do butterfly wings and TV screens have in common?
Many of the gadgets we use every day work by controlling the movement of light waves. CD and DVD players use lasers to read information off disks, allowing us to listen to music or watch movies. Optical fibers carry information signals long distances, in the form of light, allowing telephones and other devices to "talk" to each other.

Europe's first farmers
People migrating from the Middle East brought farming techniques to present-day Germany and other parts of central Europe about 7,500 years ago. For years, scientists have been arguing over whether people with European ancestors are closely related to these first farmers. Some scientists say yes. Others say no – and argue instead that people with European roots are closely related to the humans who lived in Europe long before the first farmers showed up.

Words versus sentences
It's pretty easy to tell the difference between a word and a sentence. But how your brain works when it reads a word versus how it works when it reads a sentence is still a mystery.

Trees protected villages from tsunami waves
In India, trees growing along the coastline helped to protect villages from the "walls of water" or tsunami waves that were triggered by a powerful earthquake that struck beneath the Indian Ocean on 26 December 2004, scientists have discovered.

Logging, a bigger threat to the rainforest than we knew
The amount of land in the Amazon rainforest that's being damaged by human activities is twice as large as we had previously thought, suggests a new study. That's because researchers didn't have a good idea of how much logging was occurring there, until now.

Green ocean machine
The plants in the window, the trees outside and the broccoli in the refrigerator all have ancient ancestors that didn't used to be green. They only "got green" when they captured smaller green creatures that turn sunlight into food. These small green creatures eventually became the green "chloroplasts" that the plants use to capture energy from the sun through the process of photosynthesis.

If the moon didn’t get chicken pox, then
Scars that look like miniature moon craters on your skin are not normally a mystery: a childhood case of the chicken pox is often responsible. What caused the craters on the moon, Mars, Earth, Venus and Mercury is not so obvious. In fact, this "whodunnit" is one of the mysteries of astronomy.

Learning about humans by watching chimps
If you've ever looked into the intelligent eyes of a chimpanzee at the zoo, you may have had the feeling that this animal was looking back at you with the same type of curiosity. Our two species have many similarities. We find creative ways to solve problems. We nurture and make each other feel better. We're also capable of being bullies.
