Origen publishes in Nature a robust and versatile method for creating transgenic chickens
Origen Therapeutics announced today that it has succeeded in developing a robust and versatile technology for genetically modifying chickens that, for the first time, puts avian transgenics on a par with transgenic mice.   view more (2006-06-08)

Study finds how organs monitor themselves during early development
How are you? In biological terms this question could involve a feedback loop that lets the body check in on itself and then act on that information   view more (2006-08-28)

Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory
Scientists in the UK have proved that human embryonic stem cells can develop in the laboratory into the early forms of cells that eventually become eggs or sperm.   view more (2005-06-20)

Sperm created in the laboratory from embryonic stem cells produce viable progeny
Scientists have demonstrated for the first time that embryonic stem (ES) cells cultured in the laboratory can produce sperm with the capacity to produce viable offspring.   view more (2006-07-12)

Treating male infertility with stem cells
New research has examined the usefulness of bone marrow stem cells for treating male infertility, with promising results. The related report by Lue et al, "Fate of bone marrow stem cells transplanted into the testis: potential implication for men with testicular failure," appears in the... view more (2007-03-02)

Penn Veterinary Medicine report new strategy to create genetically modified animals
Researchers at the University of Pennsylvania School of Veterinary Medicine have demonstrated the potential of a new strategy for genetic modification of large animals.   view more (2007-09-21)

Study of planarians offers insight into germ cell development
The planarian is not as well known as other, more widely used subjects of scientific study - model creatures such as the fruit fly, nematode or mouse.   view more (2007-04-25)

Oregon researchers show how resident bacteria shape gut development
University of Oregon researchers have shown that bacteria residing in the intestine shape gut development by means of several distinct signaling mechanisms.   view more (2006-06-22)

Born under the sun: UV light and the origin of life
Early evolution of life as we know it may have depended on DNA's ability to absorb UV light. This insight into the early moments of life on Earth comes from research published today in the journal BMC Evolutionary Biology. The research fills in one of the major gaps in our understanding about the... view more (2003-05-27)

Study hints at role of stem cell genes in testicular, breast cancers
UCSF scientists have discovered that the activity of several embryonic stem cell genes is elevated in testicular and breast cancers, providing some of the first molecular evidence of a link between embryonic stem cells and cancer.   view more (2005-11-30)

Sperm stem cells closer to being like embryonic stem cells
New experiments that prevented rat sperm stem cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body.   view more (2005-11-16)

New evidence of radiation risk in childhood leukaemia
Ionising radiation has long been recognised as a cause of leukaemia in exposed children. But delegates at a conference in London today (Tuesday 7 September) will hear how ground-breaking research is now providing evidence that the children of men exposed to radiation may also be at increased risk... view more (2004-09-05)

New research: Soy germ isoflavones reduce bone loss
A new study published in this month's European Journal of Nutrition demonstrates a strong correlation between reducing bone loss in non-obese postmenopausal women and the dose-dependent effect of soy germ isoflavones.   view more (2006-07-07)

Early-stage sperm cells created from human bone marrow
Human bone marrow has been used to create early-stage sperm cells for the first time, a scientific step forward that will help researchers understand more about how sperm cells are created.   view more (2007-04-13)

Guidance of Primordial Germ Cell Migration by the Chemokine SDF-1
Identification of the molecular cues governing cell migration is of major importance for the understanding of tissue and organ development and for therapy in cases of diseases resulting from aberrant cell movement. Primordial Germ Cell (PGC) migration is a useful model for studying directional cell... view more (2002-11-27)

X-Ray For Grain
Researchers from St. Petersburg have invented a way to check the viability of grains and seeds of agricultural plants without prior germination. The scientists assume that injuries of the germ and tissues of seeds can be revealed through X-ray photomicrography with the help of computer recognition... view more (2003-02-20)

Signaling for cartilage
Skeletal progenitor cells differentiate into cartilage cells when one master gene actually suppresses the action of another, said Baylor College of Medicine researchers in a report that appears online in the journal Proceedings of the National Academy of Sciences.   view more (2006-11-28)

Whooping cough persistence traced to key toxin
A key toxin associated with whooping cough helps the germs resist the human immune system and infect vaccinated populations.   view more (2005-12-19)

Zooming in on genetic shuffling
Genetic recombination, the process by which sexually reproducing organisms shuffle their genetic material when producing germ cells, leads to offspring with a new genetic make-up and influences the course of evolution.   view more (2008-07-11)

New Model for Autism Suggests Women Carry the Disorder and Explains Age as a Risk Factor
A new model for understanding how autism is acquired has been developed by a team of researchers led by Cold Spring Harbor Laboratory (CSHL) and Albert Einstein College of Medicine. Autism is a developmental disorder, characterized by language impairments, social deficits, and repetitive behaviors.   view more (2007-07-25)

A key to male fertility
Until now, mutations of the LH hormone receptor were the only explanation known for sexual precocity in boys. A team at the Institute of Genetics and Molecular and Cellular Biology (IGBMC, CNRS / Inserm / Université Louis Pasteur de Strasbourg)), in collaboration with researchers at the... view more (2007-03-05)

Study reconciles long-standing contradiction of deep-earth dynamics
Researchers at Columbia University's Lamont-Doherty Earth Observatory recently resolved a long-standing contradiction about the workings of the deep Earth.   view more (2005-08-25)
