Small, speedy plant-eater extends knowledge of dinosaur ecosystems
|
|
|
Dinosaurs are often thought of as large, fierce animals, but new research highlights a previously overlooked diversity of small dinosaurs. Paleontologists have now described a new dinosaur, the smallest plant-eating dinosaur species known from Canada.

Forecast for Saturn's moon Titan: Wild weather could be ahead
|
|
|
Saturn's moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct. Scientists think that as the seasons change in Titan's northern hemisphere, waves could ripple across the moon's hydrocarbon seas, and hurricanes could begin to swirl over these areas, too. The model predicting waves tries to explain data from the moon obtained so far by NASA's Cassini spacecraft. Both models help mission team members plan when and where to look for unusual atmospheric disturbances as Titan summer approaches.

Promising new approach to treatment of lung cancer
|
|
|
Researchers have developed a new drug delivery system that allows inhalation of chemotherapeutic drugs to help treat lung cancer, and in laboratory and animal tests it appears to reduce the systemic damage done to other organs while significantly improving the treatment of lung tumors -- the tumors virtually disappeared.

Fast new, one-step genetic engineering technology
|
|
|
A new, streamlined approach to genetic engineering drastically reduces the time and effort needed to insert new genes into bacteria, the workhorses of biotechnology, scientists are reporting. The method paves the way for more rapid development of designer microbes for drug development, environmental cleanup and other activities.
