The first "test tube baby" was born in 1978. With advances in reproductive science, an estimated one percent of all American babies are now born each year through in vitro fertilization ¬¬(IVF). But IVF and other assisted fertility treatments may be solving one problem by creating another, suggests new evidence from Tel Aviv University.

The most detailed national vegetation U.S. land-cover map to date was released today by the U.S. Geological Survey (USGS). The map will enable conservation professionals to identify places in the country with sufficient habitat to support wildlife.
The map, produced by the USGS Gap Analysis Program (GAP), can be viewed online and downloaded for free.
Researchers from the Peninsula Medical School, working in collaboration with colleagues from Glasgow Royal Infirmary and the University of Brighton, have used a unique collection of pancreas specimens taken from patients who died soon after diagnosis of type 1 diabetes to show that they respond to the ongoing process of destruction by inducing their islet cells to proliferate.
The research is published on-line at Diabetologia and is funded by Juvenile Diabetes Research Foundation.
There is a new path to defeat systemic sclerosis, also called scleroderma because of the hardening of the skin of the patients (from Greek skleros, "hard", and derma, "skin"). This path involves the B-cell of the immune system, so far only considered "innocent spectators," as Catholic University rheumatologist Gianfranco Ferraccioli, among the authors of the important research, puts it.
While South Africa comes under the world's spotlight for the World Cup, it is being scrutinised by a University of Leicester researcher because of an innovative policy initiative.
Rachel Tate, a PhD research student in the Department of Politics and International Relations at the University of Leicester, is focussing on the Maputo Development Corridor, a cross-border spatial development initiative.
Why are the international climate negotiations moving so slowly? Because countries have so far been unable to define what global fairness really is, says Thomas Sterner, Professor of Environmental Economics at the University of Gothenburg. Sterner and several other prominent economists including several recipients of the Nobel Prize in Economics spoke at the World Bank conference on development economics in Stockholm recently.
Women were just as likely to have breast abnormalities picked up by a specially trained nurse practitioner as a consultant breast surgeon, according to research published in the July issue of the Journal of Advanced Nursing.
Researchers at Glamorgan Hospital, Wales, UK, compared the findings of 126 women examined by a nurse practitioner and consultant surgeon referred to a symptomatic breast disease clinic over a 13-month period.
They produced exactly the same results in 92 per cent of cases.
A new study led by University of Leicester researchers at Glenfield Hospital suggests that CT scans may be the way forward for monitoring progression of severe asthma as well as checking how it is responding to treatment.
CT scans, a series of X-ray images of the body, are usually used to detect tumours – but the Leicester study, points to their use in asthma. Preliminary results from the study will be showcased at the University of Leicester's Festival of Postgraduate Research on 24 June.
KNOXVILLE -- Research by a small group of microbiologists is revealing how marine microbes live in a mysterious area of the Earth: the realm just beneath the deep ocean floor. The ocean crust may be the largest biological reservoir on our planet.
University Hospitals Case Medical Center cardiologists have uncovered new research showing an increased risk of cancer with a group of blood pressure medications known as angiotensin-receptor blockers (ARBs).
This class of drugs is used by millions of patients not only for high blood pressure but also for heart failure, cardiovascular risk reduction and diabetic kidney disease.
Gothenburg, Sweden: Couples considering undergoing assisted reproductive technology (ART) treatment should be informed about the increased risk of congenital malformation posed by the use of ART, the annual conference of the European Society of Human Genetics will hear today (Monday). Dr. Géraldine Viot, a clinical geneticist at the Maternité Port Royal hospital, Paris, France, will say that she believed that most doctors working in ART clinics in France only told couples about such risks if they were asked specific questions.
Gothenburg, Sweden: Individual results of genetic research studies should not be disclosed to participants without careful consideration, a scientist will tell the annual conference of the European Society of Human Genetics today (Monday). Dr.
A team led by researchers from the Center for Engineering in Medicine at Massachusetts General Hospital (MGH) has developed a technique that someday may allow growth of transplantable replacement livers. In their report that will be published in Nature Medicine and is receiving early online release, the investigators describe using the structural tissue of rat livers as scaffolding for the growth of tissue regenerated from liver cells introduced through a novel reseeding process.
