Converting the “genetic blueprint” into molecular building blocks requires two basic processes: transcription, which copies the information from DNA into RNA…
Bench to Bedside “Cardiac stem cell therapy involves delivering a variety of cells into hearts following myocardial infarction or chronic cardiomyopathy,” says…
The new mechanism is called replication “Fork Stalling and Template Switching,” said Dr. James R. Lupski, Cullen professor of molecular and human genetics and…
Chromosomes shorten with every cell division. In stem cells and in cancer cells, this shortening is compensated by telomerase, an enzyme that adds short repeat…
The team analyzed the somite segmentation process that results in the formation of the vertebral column. This process is thought to be controlled by two…
Over the course of the 20th Century, doctors waged war against infectious bacterial illness with the best new weapon they had: antibiotics.But the emergence of…
A research team at Weill Cornell Medical College in New York City has identified two genes that may be crucial to the production of an immune system cytokine…
When a key gene called 14-3-3zeta is silenced, lung cancer cells can't survive on their own, researchers have found.The gene is a potential target for…
The studies from Drs. Alexander Stark and Manolis Kellis (MIT) and colleagues, and from Dr. Eric Lai (MSKCC) and colleagues, both reveal that antisense…
Histone mRNA is rapidly degraded at the end of S phase, but the mechanism by which this occurs has remained elusive, as metazoan histone mRNAs have a unique,…
In addition, the researchers, led by Marja Nevalainen, M.D., Ph.D., associate professor of Cancer Biology at Jefferson Medical College of Thomas Jefferson…
Mobile phones, notebook computers, iPods—the boom in portable computing and communications devices is dependent on rechargeable lithium-ion batteries to…
In a report published in the online open access journal Frontiers in Zoology, scientists reveal that this beetle has lost photoreceptors that are sensitive to…
Study authors Dalial Freitak, David Heckel and Heiko Vogel from the Max Planck Institute for Chemical Ecology in Jena, Germany along with Christopher Wheat…
The ancient systems of sociality in bees, wasps, termites, and ants seem to have become an obligatory way of life for these organisms as there are almost no…
Today sophisticated genetic techniques mean that superficially identical animals previously classed as members of a single species, including the frogs and…
