Size of a woman's uterus can predict whether she is at risk of having very premature twins after IVF
Using ultrasound to measure the height of a woman's uterus is a good way to predict whether or not she is at risk of having babies born prematurely if she becomes pregnant with twins after IVF. view more (2008-07-09)
Teamwork between 2 key proteins necessary for normal development and regulation of red blood cells
Virginia Commonwealth University researchers studying hemoglobin genes, mutations of which play a role in genetic blood disorders like sickle cell anemia and beta-thalassemia, have identified two proteins that are responsible for regulating overlapping groups of genes during the development of red blood cells. view more (2007-08-07)
Small mechanical forces have big impact on embryonic stem cells
Applying a small mechanical force to embryonic stem cells could be a new way of coaxing them into a specific direction of differentiation, researchers at the University of Illinois report. Applications for force-directed cell differentiation include therapeutic cloning and regenerative medicine. view more (2009-10-19)
More 'functional' DNA in genome than previously thought
Surrounding the small islands of genes within the human genome is a vast sea of mysterious DNA. While most of this non-coding DNA is junk, some of it is used to help genes turn on and off. view more (2007-12-12)
First case of successful ovarian tissue transplantation between two, nonidentical sisters
A woman, whose ovaries had failed due to damage caused by chemotherapy and radiotherapy, has received a successful ovarian transplant from her genetically non-identical sister. view more (2007-08-02)
Mount Sinai Hospital researcher makes stem cell breakthrough
In a study to be released on March 1, 2009, Mount Sinai Hospital's Dr. Andras Nagy discovered a new method of creating stem cells that could lead to possible cures for devastating diseases including spinal cord injury, macular degeneration, diabetes and Parkinson's disease. view more (2009-03-02)
Researchers discover mechanism that prevents two species from reproducing
Cornell researchers have discovered a genetic mechanism in fruit flies that prevents two closely related species from reproducing, a finding that offers clues to how species evolve. view more (2009-10-27)
Tapping into spinal cures
Stem cells which give rise to vertebrae, muscle and the spinal cord have been identified for the first time by Dr. Valerie Wilson (University of Edinburgh). "These axial stem cells could be used in the future to help replace damaged tissues after back injuries", says Dr. Wilson who will be presenting her work at the Society for... view more...

MicroRNA undermines tumor suppression
Scientists at the Whitehead Institute for Biomedical Research and the National University of Singapore have discovered the first microRNA (miRNA) capable of directly tamping down the activity of the well known tumor-suppressor gene, p53, While p53 functions to prevent tumor formation, the p53 gene is thought to malfunction in more than 50% of... view more...

Multiple pregnancies: Vienna meeting reveals new research
The continuing high rate of multiple pregnancies in assisted reproduction is a major medical, psychosocial and economic problem. But it could be solved overnight if only doctors weren't too hesitant to act, a leading Swedish specialist in reproductive medicine told a news briefing today (Monday 1 July) at the annual meeting of the European Society... view more...

Drosophila drug screen for fragile X syndrome finds promising compounds and potential drug targets
Scientists using a new drug screening method in Drosophila (fruit flies), have identified several drugs and small molecules that reverse the features of fragile X syndrome -- a frequent form of mental retardation and one of the leading known causes of autism. view more (2008-03-10)
Joslin Researchers Discover a Surprising Culprit in the Search for Causes of Diabetic Birth Defects
Over the past several years, Joslin Investigator Mary R. Loeken, Ph.D., and her colleagues at Joslin Diabetes Center have unlocked several mysteries behind what puts women with diabetes more at risk of having a child with birth defects. view more (2007-03-06)
Risk of ectopic pregnancies after IVF declines with age in women with tubal disease
The first study to look at the risk of ectopic[1] pregnancies after IVF in a complete national ART register has unearthed a surprising result, a conference of international fertility experts heard today (Tuesday 1 July). The researchers found that women face a slightly increased risk of ectopic pregnancies after IVF. More surprisingly, they found... view more... (2003-06-28)
Scientists crack genetic secrets of human egg
The human egg's ability to transform into a new life, or into new cells that may someday save lives, is well documented. The mystery lies in the mechanics-in how a single cell can transform so nimbly. view more (2006-09-06)
Small peptide found to stop lung cancer tumor growth in mice
In new animal research done by investigators at Wake Forest University School of Medicine, scientists have discovered a treatment effective in mice at blocking the growth and shrinking the size of lung cancer tumors, one of the leading causes of cancer death in the world. view more (2009-08-27)
World-first study finds that families with babies born after embryo donation are doing well, but only a third of parents plan to tell their children how they were conceived
World-first study finds that families with babies born after embryo donation are doing well, but only a third of parents plan to tell their children how they were conceived Berlin, Germany: The world's first study of families in which babies have been born from donated embryos has revealed that only a third of parents planned to tell their... view more...

Engineering Bouncing Babies, One at a Time
As hopeful moms-to-be learn, there are important considerations to the successful implantation of a fertilized human egg. A calm environment, regular hormonal injections and the timing of the implantation can all affect the outcome of an in-vitro procedure. view more (2009-03-03)
World-first stem cell research could aid male infertility
Scientists have shown for the first time that sperm grown from embryonic stem cells can be used to produce offspring. view more (2006-07-11)
Beaked, bird-like dinosaur tells story of finger evolution
Scientists have discovered a unique beaked, plant-eating dinosaur in China. The finding, they say, demonstrates that theropod, or bird-footed, dinosaurs were more ecologically diverse in the Jurassic period than previously thought, and offers important evidence about how the three-fingered hand of birds evolved from the hand of dinosaurs. view more (2009-06-18)
Absence of critical protein linked to infertility
Researchers at the University of Illinois at Urbana-Champaign report that experiments involving mice - to be detailed in the Proceedings of the National Academy of Sciences - indicate that the transcription factor protein C/EBPb must be present in the uterus for pregnancy to occur. view more (2006-01-17)
