The Canadian Rocky Mountains were formed when the North American continent was dragged westward during the closure of an ocean basin off the west coast and collided with a microcontinent over 100 mill..

A new study shows that banded iron formations originated from oxidized iron, confirming the relevance and accuracy of existing models — a finding of great importance to the geological community.

New research suggests that sexual reproduction is favored by selection because, unlike asexual reproduction, it not only provides important evolutionary advantages in constantly changing environments,..

For engineers, polar bear hair is a dream template for synthetic materials that might lock in heat just as well as the natural version. Now, materials scientists have developed such an insulator, repr..

Scientists once thought that neurons, or possibly heart cells, were the oldest cells in the body. Now, researchers have discovered that the mouse brain, liver and pancreas contain populations of cells..

One of the world's most important plant families has a history extending much farther south than any live or fossil specimen previously recorded, as shown by chinquapin fruit and leaf fossils une..

A new study using mouse neural crest tissue reveals how primitive, undifferentiated cells choose their adult fate. The findings help explain how some neural crest cells become craniofacial cells, whil..

Researchers have discovered that learned behaviors can be inherited for multiple generations in C. elegans, transmitted from parent to progeny via eggs and sperm cells.

Research provides a possible new reason why human disease burden increases so sharply from the sixth decade of life onward as health-protective mechanisms disappear.

A Japanese plant species with a peculiar leaf pattern recently revealed unexpected insight into how almost all plants control their leaf arrangement.
