Study finds mutating stem cells
A new study finds 138 stem cell lines that change genetically after growing in the laboratory, allowing for their elimination.
Video game players advancing genetic research
Thousands of video game players have helped significantly advance our understanding of the genetic basis of diseases such as Alzheimer's, diabetes and cancer over the past year. They are the...
How cells remove bits of RNA from DNA strands
When RNA component units called ribonucleotides become embedded in genomic DNA, which contains the complete genetic data for an organism, they can cause problems for cells. It is known that...
Acquired traits can be inherited via small RNAs
Researchers have found the first direct evidence that an acquired trait can be inherited without any DNA involvement. The findings suggest that Lamarck, whose theory of evolution was eclipsed by...

Researchers hope to build universal human age estimator
(PhysOrg.com) -- As humans, we have a knack for estimating another persons age quite accurately just by glancing at their face. Although age estimation may seem relatively simple to us,...
Bacteria convert wastewater chemicals into toxic form
(PhysOrg.com) -- While traces of pharmaceutical compounds are commonly present in wastewater, interactions with bacteria during the treatment process could transform them from non-toxic to toxic forms, a new study...
Insight: Stem cell therapy poised to come in from the cold
(Reuters) - A rogue surgeon injects stem cells from a fetus into a sick man's brain. The cells morph and form body parts. When the man dies, the pathologist finds...
