Video: Could cancer be our oldest ancestor?

(PhysOrg.com) -- Despite decades of research and billions of dollars, cancer remains a major killer, with an uncanny ability to evade both the body's defenses and medical intervention. Now an Arizona State ...

(PhysOrg.com) -- In an interplanetary meeting of the minds, astrobiologists and oncologists have worked together to provide new insights into the origins of cancer, which remains a major killer despite the ...

Astrobiologists have often pondered "life as we do not know it" in the context of extraterrestrial life, says Paul Davies, an internationally acclaimed theoretical physicist and cosmologist at Arizona State University. "But," ...

A U.S. biologist says his discovery of a molecule that induces the dispersion of biofilms will affect numerous industries during coming years.

Instead of killing cancer cells, researchers at Arizona State University will use the laws of physics to figure out how to control them. And, rather than treating cancer as a disease and seeking a cure, ASU scientists will ...

"The Search for Extraterrestrial Intelligence (SETI) has been dominated for its first half century by a hunt for unusual radio signals. But as he prepares for the publication of his new book The Eerie Silence: Are We Alone?," ...

Many genes are transcribed into messenger RNA (mRNA) molecules that provide instructions for protein synthesis. Other genes encode regulatory RNAs known as 'microRNAs', which can block protein translation ...

Mapping all of the chemical, or epigenetic, changes to chromosomes that affect which genes are turned on or off—and thus determine the fate of genomically identical cells in the body—usually requires ...

When studying any kind of population—people or cells—averaging is a useful, if flawed, form of measurement. According to the US Census Bureau, the average American household size in 2010 was 2.59. Of ...

Environment is not the only factor in shaping regulatory patterns—and it might not even be the primary factor, according to a new Rice University study that looks at how cells' protein networks relate to ...

Researchers at University of Cincinnati have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources – lakes and rivers – at a significantly higher ...

How does the bacterium Shigella—the cause of a deadly diarrheal disease—detect that it's in a human host? Ohio University scientists have found that a biological "RNA thermometer" monitors whether the environment is rig ...
