Vacuum-like device makes cellular exploration easier

It's a bit of a challenge. But, imagine a microscopic jet vacuum cleaner, the size of a pen nib that hovers over cell surfaces without ever touching them. Then imagine that the soap in the cleaning solution is replaced with ...

Earth's oldest fossils boost hopes for life on Mars

(PhysOrg.com) -- Microfossils found in Australia show that more than 3.4 billion years ago, bacteria thrived on an Earth that had no oxygen, a finding that boosts hopes life has existed on Mars, a study published Sunday says.

Embryo development obeys the laws of hydrodynamics

Vincent Fleury, a researcher at the Paris Diderot University, studied the early stage of development when embryonic cells first form a flat sheet of cells before folding into a U-shape, resembling a folded pancake. He demonstrated ...

Scientists create stable, self-renewing neural stem cells

In a paper published in the April 25 early online edition of the Proceedings of the National Academy of Sciences, researchers at the University of California, San Diego School of Medicine, the Gladstone Institutes in San ...

Researchers illuminate laminin's role in cancer formation

Laminin, long thought to be only a structural support protein in the microenvironment of breast and other epithelial tissue, is “famous” for its cross-like shape. However, laminin is far more than just a support ...

Looking at cancer progression as evolutionary process

Two University of Oregon biologists have launched an ambitious, highly focused effort to identify genetic changes that occur from the formation of a single mutation to full-fledged cancer.
