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.
Six Threats to Chromosomes

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. 
Telomeres in Disease
Rodrigo Calado and Neal Young | May 1, 2012
Telomeres have been linked to numerous diseases over the years, but how exactly short telomeres cause diseases and how medicine can prevent telomere erosion are still up for debate.
Building a Better Sheep

Chinese scientists claim to have cloned a lamb carrying a roundworm gene that aids in the production of polyunsaturated fatty acids.
Stem Cell Researcher Fabricates Data
Edyta Zielinska | Apr 16, 2012
A scientist who claimed to have injected monkey embryonic stem cells into the eyes of rats to improve their vision accepts the penalty for research misconduct.
Plant RNA Paper Questioned
Emily Willingham | Apr 16, 2012
Remarkable findings of ingested plant miRNA in animal liver and blood draw speculation about the study’s validity.
