In development, it's all about the timing (7/24/2014)

In development, it's all about the timingClosely related organisms share most of their genes, but these similarities belie major differences in behavior, intelligence, and physical appearance. Scientists are beginning to appreciate that the timing of the events that happen during development plays a decisive role in defining an organism. Today, a team of scientists at CSHL has identified LIN-42 as a key regulator of developmental timing, governing a broad range of events throughout maturation. ...> Full Article


A region and pathway found crucial for facial development in vertebrate embryos (7/24/2014)

A signaling pathway once thought to have little if any role during embryogenesis is a key player in the formation of the front-most portion of developing vertebrate embryos. Moreover, signals emanating from this region -- referred to as the 'extreme anterior domain' -- orchestrate the complex choreography that gives rise to proper facial structure. ...> Full Article


Danish DNA could be key to happiness (7/23/2014)

Genetics could be the key to explaining nation's levels of happiness, according to research from the University of Warwick. Economists at the University's Centre for Competitive Advantage in the Global Economy have looked at why certain countries top the world happiness rankings. In particular they have found the closer a nation is to the genetic makeup of Denmark, the happier that country is. ...> Full Article


Mutation stops worms from getting drunk (7/23/2014)

Mutation stops worms from getting drunkNeuroscientists at The University of Texas at Austin have generated mutant worms that do not get intoxicated by alcohol, a result that could lead to new drugs to treat the symptoms of people going through alcohol withdrawal. The scientists accomplished this feat by inserting a modified human alcohol target into the worms, as reported this week in The Journal of Neuroscience. ...> Full Article


Transplanting gene into injured hearts creates biological pacemakers (7/22/2014)

Cardiologists at the Cedars-Sinai Heart Institute have developed a minimally invasive gene transplant procedure that changes unspecialized heart cells into 'biological pacemaker' cells that keep the heart steadily beating. ...> Full Article


Improving tumour radiation therapy: When basic ions break DNA down (7/22/2014)

Scientists now have a better understanding of how short DNA strands decompose in microseconds. A European team found new fragmentation pathways that occur universally when DNA strands are exposed to metal ions from a family of alkaline and alkaline earth elements. These ions tend to replace protons in the DNA backbone and at the same time induce a reactive conformation leading more readily to fragmentation. These are findings published in a study in EPJ D. ...> Full Article


A new genome editing method brings the possibility of gene therapies closer to reality (7/21/2014)

This study published online in Cell Stell Cell provides an important theoretical foundation for stem cell-based gene therapy. ...> Full Article


Chimpanzee intelligence determined by genes (7/20/2014)

A chimpanzee's intelligence is largely determined by its genes, while environmental factors may be less important than scientists previously thought, according to a Georgia State University research study. ...> Full Article


Scientists develop technology to redirect proteins towards specific areas of the genome (7/20/2014)

Scientists develop technology to redirect proteins towards specific areas of the genomeThe Spanish National Cancer Research Centre Macromolecular Crystallography Group has managed to reprogram the binding of a protein called BuD to DNA in order to redirect it towards specific DNA regions. Guillermo Montoya, the researcher who led the study, says the discovery: 'will allow us to modify and edit the instructions contained in the genome to treat genetic diseases or to develop genetically-modified organisms.' ...> Full Article


Tiny DNA pyramids enter bacteria easily -- and deliver a deadly payload (7/19/2014)

Bacterial infections usually announce themselves with pain and fever but often can be defeated with antibiotics -- and then there are those that are sneaky and hard to beat. Now, scientists have built a new weapon against such pathogens in the form of tiny DNA pyramids. Published in the journal ACS Applied Materials & Interfaces, their study found the nanopyramids can flag bacteria and kill more of them than medicine alone. ...> Full Article


Scientists first to reconstitute the DNA 'replication fork' (7/18/2014)

While scientists have had an idea of the molecular tools that cells use to replicate DNA -- the enzymes that unzip the double-stranded DNA and create 'daughter' copies -- they did not have a clear picture of how the process works. Now, researchers at Rockefeller University have built the first model system to decipher what goes on at the 'replication fork' -- the point where DNA is split down the middle in order to create two exact copies. ...> Full Article


Same genes drive maths and reading ability (7/17/2014)

Around half of the genes that influence how well a child can read also play a role in their mathematics ability, say scientists from UCL, the University of Oxford and King's College London who led a study into the genetic basis of cognitive traits. ...> Full Article


DNA origami nano-tool provides important clue to cancer (7/16/2014)

DNA origami nano-tool provides important clue to cancerResearchers at Karolinska Institutet in Sweden have headed a study that provides new knowledge about the EphA2 receptor, which is significant in several forms of cancer. This is important knowledge in itself -- but just as important is how this study, which is published in the highly respected journal Nature Methods, was conducted. ...> Full Article


Pseudogenes may provide clearer understanding of biomarkers (7/16/2014)

Pseudogenes may provide clearer understanding of biomarkersThe results indicated that the science of pseudogene expression analysis may very well play a key role in explaining how cancer occurs by helping medical experts in the discovery of new biomarkers. The study's findings appear in today's issue of Nature Communications. ...> Full Article
