DNA Hard Drive
Megan Scudellari | May 23, 2012
Researchers design the first rewritable biological data storage system.
Live Slow, Die Old
Ed Yong | May 17, 2012
Ancient bacteria living in deep-sea sediments are alive—but with metabolisms so slow that it’s hard to tell.
Synchronized Clocks
Megan Scudellari | May 16, 2012
Researchers identify the first circadian clock component conserved across all three domains of life.
Gene Signaling by Remote
Edyta Zielinska | May 7, 2012
Nanoparticles in mice can be switched on to activate insulin production using a radio signal.
Doubled Gene Boosted Brain Power
Sabrina Richards | May 7, 2012
Human-specific duplications of a gene involved in brain development may have contributed to our species’ unique intelligence.
Six Threats to Chromosomes
Ed Yong | May 3, 2012
Researchers identify two new DNA repair systems, in addition to four that were already known, that can attack unprotected telomeres.
Stem Cell Suicide Switch
Megan Scudellari | May 3, 2012
Human embryonic stem cells swiftly kill themselves in response to DNA damage.
Nervous Mice Get Worse Cancer
Edyta Zielinska | May 3, 2012
Anxious mice are more likely to come down with aggressive skin cancer than those who show less stress on behavioral tests.
Telomere Basics
Telomere Basics
Rodrigo Calado and Neal Young | May 1, 2012
Telomeres are repetitive, noncoding sequences that cap the ends of linear chromosomes. They consist of hexameric nucleotide sequences (TTAGGG in humans) repeated hundreds to thousands of times. 
The Sugar Lnc
Sabrina Richards | May 1, 2012
Genes that react to cellular sugar content are regulated by a long non-coding RNA via an unexpected mechanism
