DNA molecules in moss open door to new biotechnology
Plasmids, which are DNA molecules capable of independent replication in cells, have played an important role in gene technology. view more (2009-11-09)
Predicting cancer prognosis
Researchers led by Dr. Soheil Dadras at the Stanford University Medical Center have developed a novel methodology to extract microRNAs from cancer tissues. view more (2009-08-28)
Reprogramming Human Cells Without Inserting Genes
A research team comprised of faculty at Worcester Polytechnic Institute's (WPI) Life Sciences and Bioengineering Center (LSBC) and investigators at CellThera, a private company also located at the LSBC, has discovered a novel way to turn on stem cell genes in human fibroblasts (skin cells) without the risks associated with inserting extra genes or... view more...

Researchers rapidly turn bacteria into biotech factories
High-throughput sequencing has turned biologists into voracious genome readers, enabling them to scan millions of DNA letters, or bases, per hour. view more (2009-07-27)
Researchers Look to Imprinted Genes for Clues to Fetal Growth Restriction in Cloned Swine
Researchers at North Carolina State University have found that intrauterine growth restriction (IUGR), which results in low birth weight and long-term deleterious health effects in cloned swine, is linked to a type of gene - known as an imprinted gene - found only in placental mammals. view more (2009-07-21)
MU scientists convert pigs' connective tissue cells into stem cells
For years, proponents have touted the benefits of embryonic stem cell research, but the potential therapies still face hurdles. view more (2009-06-26)
Universitat Autonoma de Barcelona researchers first to clone mice in Spain
Researchers at the Department of Cell Biology, Physiology and Immunology at Universitat Autònoma de Barcelona (UAB) are the first to have cloned mice in Spain. Cloe, Cleo and Clona are three female brown-coloured mice and were born respectively on 12 May, 3 June and 10 June. view more (2009-06-12)
First live 'cloning' of faces challenges assumptions about human behavior
Computer scientists at the University of East Anglia (UEA) have developed a new way of cloning facial expressions during live conversations to help us better understand what influences our behaviour when we communicate with others. view more (2009-06-01)
Deadly parasite's rare sexual dalliances may help scientists neutralize it
For years, microbiologist Stephen Beverley, Ph.D., has tried to get the disease-causing parasite Leishmania in the mood for love. view more (2009-04-10)
Therapeutic cloning gets a boost with new research findings
Germ cells, the cells which give rise to a mammal's sperm or eggs, exhibit a five to ten-fold lower rate of spontaneous point mutations than adult somatic cells, which give rise to the body's remaining cell types, tissues and organs. Despite their comparatively higher mutation rates, however, adult somatic cells are used as the donor cells in a... view more... (2009-03-25)
Rice University's Baker Institute experts available to discuss stem cell research, recommendations
Rice University's Baker Institute has experts available to discuss the current debate on United States' embryonic stem cell policy. view more (2009-02-18)
Animal eggs not suitable substitutes to produce stem cells
Since the cloning of Dolly the Sheep over a decade ago, somatic cell nuclear transfer (SCNT) has been considered a promising way to generate human, patient-specific stem cells for therapeutic applications. view more (2009-02-03)
Stem cell research puts interstate rivalry on hold
Victoria and New South Wales have put aside their competitive interstate rivalry to collaborate on a stem cell research project, as announced by Innovation Minister Gavin Jennings and NSW Minister for Science and Medical Research, Verity Firth, today. view more (2008-09-04)
Evolution of fruit size in tomato
Domesticated tomatoes can be up to 1000 times larger than their wild relatives. How did they get so big? In general, domesticated food plants have larger fruits, heads of grain, tubers, etc, because this is one of the characteristics that early hunter-gatherers chose when foraging for food. view more (2008-06-30)
Researchers report the cloning of a key group of human genes, the protein kinases
Although the human genome has been sequenced, research into mechanism of action of genes has been hampered by the fact that most human genes have not been isolated. This is true for even the most common class of cancer-associated genes, the protein kinases, which mediate the majority of signaling events in cells by phosphorylating and modulating... view more...

Ovarian cancer stem cells identified, characterized
Researchers at Yale School of Medicine have identified, characterized and cloned ovarian cancer stem cells and have shown that these stem cells may be the source of ovarian cancer's recurrence and its resistance to chemotherapy. view more (2008-04-18)
Therapeutic cloning treats Parkinson's disease in mice
Research led by investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) has shown that therapeutic cloning, also known as somatic-cell nuclear transfer (SCNT), can be used to treat Parkinson's disease in mice. The study's results are published in the March 23 online edition of the journal Nature Medicine. view more (2008-03-24)
DFG remains skeptical of the cloning of human cells
According to a paper published in the journal Stem Cells, an American group has succeeded in inserting cell nuclei from human skin cells into human enucleated oocytes and to stimulate these new cells to undergo cell division in the laboratory. view more (2008-01-23)
Scripps research scientists find new genetic mutation that halts the development of lupus
The lupus-suppressing action is the result of what is known as a nonsense mutation of the Coronin-1A gene (Coro1a) required for the development of the disease. view more (2008-01-18)
US presidential candidates and their views on scientific issues
What are the United States presidential candidates' positions on scientific topics ranging from evolution to global warming? A special news report, which is being published in the 4 January issue of the journal Science, addresses these questions and profiles the nine leading candidates on where they stand on important scientific issues. view more (2008-01-04)
