Consider the marvel of the embryo. It begins as a glob of identical cells that change shape and function as they multiply to become the cells of our lungs, muscles, nerves and all the other specialized tissues of the body. Now, in a feat of reverse tissue engineering, Stanford University researchers have begun to unravel the complex genetic coding that allows embryonic cells to proliferate and transform into all of the specialized cells that perform myriad biological tasks. A team of...

The phenomenon has long been known in psychology: traumatic experiences can induce behavioral disorders that are passed down from one generation to the next. It is only recently that scientists have begun to understand the physiological processes underlying hereditary trauma. "There are diseases such as bipolar disorder, that run in families but can't be traced back to a particular gene", explains Isabelle Mansuy, professor at ETH Zurich and the University of Zurich. With her research group...

From time to time, living cells will accidentally make an extra copy of a gene during the normal replication process. Throughout the history of life, evolution has molded some of these seemingly superfluous genes into a source of genetic novelty, adaptation and diversity. A new study shows one way that some duplicate genes could have long-ago escaped elimination from the genome, leading to the genetic innovation seen in modern life. Researchers have shown that a process called DNA...

Some three billion base pairs make up the human genome—the floor plan of life. In 2003, the Human Genome Project announced the successful decryption of this code, a tour de force that continues to supply a stream of insights relevant to human health and disease. Nevertheless, the primary actors in virtually all life processes are the proteins coded for by DNA sequences known as genes. For a broad spectrum of diseases, proteins can yield far more compelling revelations than may be gleaned...

UC Riverside-led research could help identify new anti-malaria strategies A research team led by a cell biologist at the University of California, Riverside has generated a 3D model of the human malaria parasite genome at three different stages in the parasite's life cycle — the first time such 3D architecture has been generated during the progression of the life cycle of a parasite. The parasite that causes malaria in humans is Plasmodium falciparum. The female Anopheles mosquito...

Not so long ago researchers thought that RNAs came in two types: coding RNAs that make proteins and non-coding RNAs that have structural roles. Then came the discovery of small RNAs that opened up whole new areas of research. Now researchers have come full circle and predicted that some long non-coding RNAs can give rise to small proteins that have biological functions. A recent study in The EMBO Journal describes how researchers have used ribosome profiling to identify several hundred long...

As the Earth’s human population marches toward 9 billion, the need for hardy new varieties of grain crops has never been greater. It won’t be enough to yield record harvests under perfect conditions. In an era of climate change, pollution and the global spread of pathogens, these new grains must also be able to handle stress. Now, researchers at Michigan Technological University have identified a set of genes that could be key to the development of the next generation of super rice....

Non-coding DNA sequences found in all plants may have undiscovered roles in basic plant development and response to the environment DNA is the molecule that encodes the genetic instructions enabling a cell to produce the thousands of proteins it typically needs. The linear sequence of the A, T, C, and G bases in what is called coding DNA determines the particular protein that a short segment of DNA, known as a gene, will encode. But in many organisms, there is much more DNA in a cell than...

Functional Designer Chromosome In Yeast Could Lead To Better Biofuels And Medicines

Study reports major advance in synthetic biology An international team of scientists led by Jef Boeke, PhD, director of NYU Langone Medical Center's Institute for Systems Genetics, has synthesized the first functional chromosome in yeast, an important step in the emerging field of synthetic biology, designing microorganisms to produce novel medicines, raw materials for food, and biofuels. Over the last five years, scientists have built bacterial chromosomes and viral DNA, but this is...

Knockout Mouse
2013-10-02 11:52:01

A Knockout Mouse is a genetically engineered mouse in which researchers have inactivated, or “knocked out,” an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity frequently causes changes in a mouse’s phenotype, which includes appearance, behavior, or other apparent and biochemical characteristics. Knockout mice are significant animal models for studying the role of genes which have been sequenced but whose functions haven’t...

Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
