DNA encodes the information necessary to make all the proteins in a cell, but the vast majority of the DNA in a cell is non-coding DNA, in the past sometimes referred to as 'junk' DNA. Recent research has identified non-coding DNA sequences that are found in nearly all plants and appear to have roles in basic processes such as tissue and organ development, response to hormones, and regulation of gene expression.

Researchers report they can generate human motor neurons from stem cells much more quickly and efficiently than previous methods allowed. The finding will aid efforts to model human motor neuron development, and to understand and treat spinal cord injuries and motor neuron diseases such as amyotrophic lateral sclerosis.

The reason why some animals can regenerate tissues after severe organ loss or amputation while others, such as humans, cannot renew some structures has always intrigued scientists. In a new study, researchers show, for the first time, that zebrafish regenerates its caudal fin by a process that involves a specific channel in the cell membrane, called V-ATPase, that pumps hydrogen ions, generating an electrical current.

The key is the overexpression of the ATHB25 gene. This gene encodes a protein that regulates gene expression, producing a new mutant that gives the seed new properties. Researchers have proven that this mutant has more gibberellin - the hormone that promotes plant growth - which means the seed coat is reinforced as well.

Berkeley Lab researchers led the development of a new technique for identifying gene enhancers - sequences of DNA that act to amplify the expression of a specific gene - in the genomes of humans and other mammals. Called SIF-seq, this new technique complements existing genomic tools, such as ChIP-seq, and offers additional benefits.

A new microfluidic method for evaluating drugs commonly used for preventing heart attacks has found that while aspirin can prevent dangerous blood clots in some at-risk patients, it may not be effective in all patients with narrowed arteries. The study, which involved 14 human subjects, used a device that simulated blood flowing through narrowed coronary arteries to assess effects of anti-clotting drugs.
