Researchers create Methuselah fly by selecting best cells

A team of researchers at the University of Bern has managed to considerably prolong the lifespan of flies by activating a gene which destroys unhealthy cells. The results could also open new possibilities in human anti aging ...

Cell biologists discover on-off switch for key stem cell gene

Consider the relationship between an air traffic controller and a pilot. The pilot gets the passengers to their destination, but the air traffic controller decides when the plane can take off and when it must wait. The same ...

Special chromosomal structures control key genes

Within almost every human cell is a nucleus six microns in diameter—about one 300th of a human hair's width—that is filled with roughly three meters of DNA. As the instructions for all cell processes, the DNA must be ...

CMOS technology provides new insights into how biofilms form

In a study published today in Nature Communications, a research team led by Ken Shepard, professor of electrical engineering and biomedical engineering at Columbia Engineering, and Lars Dietrich, assistant professor of biological ...

Scientists discover double meaning in genetic code

Scientists have discovered a second code hiding within DNA. This second code contains information that changes how scientists read the instructions contained in DNA and interpret mutations to make sense of health and disease.

A hidden genetic code for better designer genes

Scientists routinely seek to reprogram bacteria to produce proteins for drugs, biofuels and more, but they have struggled to get those bugs to follow orders. But a hidden feature of the genetic code, it turns out, could get ...

Hairpin turn: Micro-RNA plays role in wood formation

For more than a decade, scientists have suspected that hairpin-shaped chains of micro-RNA regulate wood formation inside plant cells. Now, scientists at NC State University have found the first example and mapped out key ...
