Smart Mars Rovers

A scientist talks about a new tool for space exploration — a robot that thinks like a geologist. When a space probe sends data from Mars, the radio signal can take up to 20 minutes to travel back to Earth. And if mission controllers send a command back to the probe, it might take another 20 minutes to reach Mars. This delay makes it tough to …

The Chauvet Cave – The scientific research – Part 2

The Significance of the Cave The discovery came as a shock, and even non-specialists could recognize its originality and distinction. This response was caused by several aspects.

What creates the “washboard effect” on dirt roads?

A question from Viron Fessler of Gaston, Oregon. He writes: “We live on a gravel road. Every summer, during the dry season, the road develops ‘waves’ or ‘ripples.’ The peaks of the waves are about 10 inches apart, with matching dips. These ripples can get around 3 inches high. What creates this effect?” These are sometimes called “washboard roads” — and they’re the bumpy bane …

Asteroid Frog Extinction

Scientists think that amphibians are rapidly disappearing around the world because of their sensitivity to environmental changes. So how did frogs outlive the dinosaurs? You talk about an asteroid causing the extinction of the dinosaurs, but what about frogs? Frogs are a very delicate species, greatly affected by changes in their climate.

Biodiversity Database

In the past half billion years, life on Earth has experienced several waves of mass extinctions. The most recent — 65 million years ago — wiped out the dinosaurs. But it’s what happens to biodiversity between extinction events that interests paleobiologist John Alroy, of the University of California, Santa Barbara. John Alroy: The traditional view is that diversity has gone up and up in an exponential …

Terra Preta

In the Brazilian Amazon, the soil is poor. So farmers resort to slashing and burning trees to enrich the soil. It’s common wisdom that the natives have always practiced slash and burn techniques. But beneath the rainforest, small patches of rich, dark soil polka-dot the Amazon river basin. It’s known as Terra Preta — or Black Earth. Some scientists now think native Amazonian Indians intentionally …

Elk, Bunchgrass, and Weeds

A story about winter forage for the Rocky Mountain elk of Montana. During the summer, elk use a variety of habitats at different elevations. But winter snow cover limits their food, primarily to bunchgrasses found in valleys — valleys that are often encroached upon by human development. And there’s an even more immediate threat to elk forage — invasive plants like spotted knapweed. These weeds …
