Researchers find RIPs remain active, continue to produce new insertions in human genome

An ambitious hunt by Johns Hopkins scientists for actively "jumping genes" in humans has yielded compelling new evidence that the genome, anything but static, contains numerous pesky mobile elements that may help to explain why people have such a variety of physical traits and disease risks.

Researchers trace scent signals from nose to higher centers of mouse brain

Mice know fear. And they know to fear the scent of a predator. But how do their brains quickly figure out with a sniff that a cat is nearby?

Novel study finds unexpected link between reproductive proteins in humans, invertebrates

A novel study in the scientific journal Molecular Biology and Evolution draws a completely unexpected link between reproductive proteins in humans and proteins involved in fertilization in invertebrates, as well as mating between haploid cells in yeast. Because human and yeast are separated by 1 billion years of evolution, these findings may have important implications for our understanding of the molecular mechanisms underlying sex, and how they originated.

Research provides new clues to understand link between deficits of AGPO-3, depression

The link between deficits of omega-3 poly-unsaturated fatty acids and the onset of depressive disorders is not new in the medical field. However, what has not been known until now is the brain mechanism by which diet can condition mental health to a certain extent.

Scientists discover how stressed cells boost thrombin production

In our not-so-distant evolutionary past, stress often meant imminent danger, and the risk of blood loss, so part of our body's stress response is to stock-pile blood-clotting factors. Scientists in the Molecular Medicine Partnership Unit, a collaboration between the European Molecular Biology Laboratory in Heidelberg, Germany, and the University of Heidelberg Medical Centre, have discovered how stressed cells boost the production of the key blood-clotting factor, thrombin.

Study: 7% biodiesel blended in regular diesel does not cause greater health risks than pure fossil diesel

Up to seven per cent biodiesel blended in regular diesel will presumably not cause greater health risks for the population than the use of pure fossil diesel. This is the main conclusion in a memorandum from the Norwegian Institute of Public Health and the Climate and Pollution Control Agency (formerly SFT) to the Ministry of Health and Care Services and the Ministry of the Environment in Norway.

Engineered cells take control of the cells and microenvironment following transplantation

In work that could jumpstart the promising field of cell therapy, in which cells are transplanted into the body to treat a variety of diseases and tissue defects, researchers at Brigham and Women's Hospital (BWH) have engineered cells that could solve one of the key challenges associated with the procedure: control of the cells and their microenvironment following transplantation.

Lampreys may have dual immune defense system similar to that of humans

Biologists have discovered that primitive, predatory lampreys have structures within their gills that play the same role as the thymus, the organ where immune cells called T cells develop in mammals, birds and fish.

Cord Blood America signs second Supply Agreement with premier cell and tissue bank

Cord Blood America, Inc., the umbilical cord blood stem cell preservation company focused on bringing the life saving potential of stem cells to families nationwide and internationally, announced today that it has signed a Supply Agreement with a premier national and international cell and tissue bank to provide placenta, umbilical cord blood and whole umbilical cord collection services for research purposes.

Scientists discover how stressed cells boost production of key blood-clotting factor, thrombin

Scientists in a collaboration between EMBL Heidelberg and the University of Heidelberg Medical Centre have discovered how stressed cells boost the production of the key blood-clotting factor, thrombin. Their work, published today in Molecular Cell, shows how cancer cells may be taking advantage of this process, and opens new possibilities for fighting back against cancer and septicaemia.

Survey reveals negative impact of uncertain policy surrounding human embryonic stem cell research

While there is no doubt that the ethical controversy surrounding human embryonic stem cell (hESC) research has given rise to an uncertain policy environment, the true impact of years of frequent policy changes has not been fully assessed.

Method to comprehensively characterize human embryonic stem cell lines and iPS cell lines

Ever since researchers devised a recipe for turning adult cells into cells that look and act like embryonic stem cells, there has been lingering doubt in the field about just how close to embryonic stem cells each of those cell lines really is at a molecular and functional level. Now, researchers reporting in the February 4th issue of the journal Cell, a Cell Press publication, have developed a systematic way to lay those doubts about quality to rest.

How body's first line of defence distinguishes between microbes and own structures

This week, the highly-respected US Academy of Sciences journal (PNAS) published an article describing how the first line of defence of the human immune system distinguishes between microbes and the body's own structures.

New 'skin gun' treats burns with stem cells

A revolutionary new "skin gun" developed to treat burns could be the latest in a remarkable string of stem-cell breakthroughs poised to change the face of medicine, says Emerging Healthcare Solutions President and CEO Cindy Morrissey.

Research unmasks long sought stem cell origin of carcinoma

A constellation of different stem cell populations within our skin help it to cope with normal wear and tear. By constantly proliferating, the stem cells allow skin to replenish itself, allowing each cell to be replaced by a new one about once a month. But the normal cycle of division and death within one or more of these stem cell types can sometimes be derailed by genetic mishaps. Such events are believed to spawn carcinomas and other deadly skin cancers, which are the mostly frequently diagnosed cancers in the United States.
