The first pigs containing genes responsible for Alzheimers disease will be born in Denmark in August. This event is a landmark achivement in the effort towards finding a cure for the disease. - [Read more]

Many of the areas of the human genome previously thought to be deserts are in fact teeming with life, a scientist will tell the annual conference of the European Society of Human Genetics. Most known human genes in the genome map are still incompletely annotated, according to the researcher. - [Read more]

Researchers at the Institute for Stem Cell Biology and Medicine at UCLA were able to take normal tissue cells and reprogram them into cells with the same unlimited properties as embryonic stem cells, the cells that are able to give rise to every cell type found in the body. - [Read more]

Scientists have identified the receptor in cells of the peripheral nervous system that is most responsible for the bodys ability to sense cold. The finding reveals one of the key mechanisms by which the body detects temperature sensation. But in so doing it also illuminates a mechanism that mediates how the body experiences intense stimuli -- temperature, in this case -- that can cause pain. - [Read more]

Passive immunization through the development of fully human antibodies specific to Plasmodium falciparum may be effective at controlling the disease. - [Read more]

Scientists have developed a new biosensor that sniffs out explosives and could one day be used to detect landmines and deadly agents, such as sarin gas, according to a paper in Nature Chemical Biology. - [Read more]

The skins ability to replace the tissue it sloughs off is controlled by a variety of genes. A new study, however, identifies a "master regulator" of this regeneration process not only for skin, but for many epithelial tissues including breast, prostate, and urogenital tract. The findings also have implications for cancers of the skin, breast and prostate, which are among the most common human malignancies. - [Read more]

Experimental vaccines to help the immune system fight tumors have rarely been designed to directly stimulate helper T cells, one of the bodys most critical immune responders, because of the difficult process required to isolate and clone antigens for vaccine development. Now, a new technique may allow scientists to create a melanoma vaccine able to stimulate helper T cells. The approach may also aid in the development of other vaccines against cancers or infectious diseases. - [Read more]

A group of organisms that has never had sex in over 40 million years of existence has nevertheless managed to evolve into distinct species, says new research published today. The study challenges the assumption that sex is necessary for organisms to diversify and provides scientists with new insight into why species evolve in the first place. - [Read more]

Researchers have found that mouse oocytes that fail to become fertilized during in vitro fertilization are nevertheless often capable of succeeding as "cytoplasmic donors" during a subsequent cloning step using so-called nuclear transfer. Although the implications for human eggs are not yet clear, the findings are of interest because of the ethical and practical concerns surrounding the need for fresh human oocytes for similar nuclear-transfer procedures using human cells. - [Read more]

In the February 15th issue of Genes & Development, Dr. K. John McLaughlin and colleagues report on their success in using uniparental embryonic stem cells to replace blood stem cells in mice. Uniparental embryonic stem cells are an appealing alternative source of patient-derived embryonic stem cells, as they have several advantages over embryonic stem cell lines generated by somatic cell nuclear transfer (also known as therapeutic cloning). - [Read more]

Single-parent stem cells can proliferate normally in an adult organ and could provide a less controversial alternative to the therapeutic cloning of embryonic stem cells. - [Read more]

Using a nuclear transfer procedure, scientists at Rockefeller University and the Howard Hughes Medical Institute have, for the first time, shown reproducibly that mice can be cloned from adult stem cells. - [Read more]

The U.S. Food and Drug Administration (FDA) has issued new documents on the safety of animal cloning. "Based on FDAs analysis of hundreds of peer-reviewed publications and other studies on the health and food composition of clones and their offspring, the draft risk assessment has determined that meat and milk from clones and their offspring are as safe as food we eat every day," said Stephen F. Sundlof, D.V.M., Ph.D., director of FDAs Center for Veterinary Medicine. - [Read more]

In the wake of the Australian Senate’s decision to pass the human embryo cloning legislation, another Australian research breakthrough is likely to strengthen the case for embryonic stem cell research. University of New South Wales (UNSW) academics have proven that tumours can be prevented from forming when embryonic stem cells are transplanted. - [Read more]

A new method of introducing DNA into the genome of fruit flies promises to transform the ability of scientists to study the structure and function of virtually all the flys genes, and the method may be applicable to other frequently studied organisms such as mice. - [Read more]

Researchers at the University of California, Davis, the US Department of Agriculture and the University of Haifa in Israel have cloned a gene from wild wheat that increases the protein, zinc and iron content in the grain, potentially offering a solution to nutritional deficiencies affecting hundreds of millions of children around the world. - [Read more]

New research dismisses the notion that adult stem cells are necessary for successful animal cloning, proving instead that cells that have completely evolved to a specific type not only can be used for cloning purposes, but they may be better and more efficient. As proof, researchers report they created two mouse pups from a type of blood cell that itself is incapable of dividing to produce a second generation of its own kind. - [Read more]

Advanced Cell Technology, Inc. has announced that company scientists and their collaborators rescued visual function in rats through implantation of retinal pigment epithelial cells (RPE) derived from human embryonic stem (hES) cells. - [Read more]

A collaboration between researchers at the Salk Institute for Biological Studies and the University of California at Los Angeles captured the genome-wide DNA methylation pattern of the plant Arabidopsis thaliana - the "laboratory rat" of the plant world - in one big sweep. "In a single experiment we recapitulated 20 years worth of anecdotal findings and then some," says senior author Joseph Ecker, Ph.D., a professor in the Salk Institutes Plant Biology Laboratory. - [Read more]
