Cold Spring Harbor Protocols features innovative methods for embryology research
Two methods that permit scientists to examine critical stages in early embryogenesis are featured in this month's release of Cold Spring Harbor Protocols. view more (2007-12-04)
Fossilised Embryos - 500 Million Years Old
Evidence from fossilised embryos of worm-like creatures that lived 500 million years ago shows that embryos developed then in much the same way as their living relatives do today. The implications of this remarkable discovery, reported in this week's issue of Nature, is that embryological processes that occur today must have been established very... view more... (2004-01-12)
Embryo fossils reveal animal complexity 10 million years before Cambrian Explosion
Fossilized embryos predating the Cambrian Explosion by 10 million years provide evidence that early animals had already begun to adopt some of the structures and processes seen in today's embryos, say researchers from Indiana University Bloomington and nine other institutions in this week's Science. view more (2006-10-13)
Drug could improve pregnancy outcomes in wider range of women with insulin resistance
Women who are obese, have type 2 diabetes or a family history of type 2 diabetes could one day have more successful pregnancies because of a study at Washington University School of Medicine in St. Louis. view more (2007-09-07)
Children born from frozen embryos weigh more and do better than those born after fresh transfer
Children born after a frozen, thawed embryo has been replaced in the womb have higher birth weight than those born where fresh embryos were used. view more (2008-07-08)
New method of assessing women's eggs could enhance IVF success, Stanford study shows
Many couples who have trouble conceiving a child have turned to a process known as in vitro fertilization. The resulting embryos are then transferred back into the woman or placed in storage. view more (2009-03-24)
Ethical Guidelines Presented for Swedish Stem Cell Research
In brief, the guidelines mean that researchers may take stem cells from embryos that can no longer be used for further IVF treatment. Moreover, the creation of embryos by somatic cell nuclear transfer (therapeutic cloning) to get access to stem cells is deemed to be ethically defensible. The reason for this is the prospect of major long-term... view more... (2001-12-04)
Identifying the metabolism of a healthy embryo could improve infertility treatment
Embryos that are most likely to result in a pregnancy are crucial to the success of in vitro fertilization (IVF) but are difficult to identify. Researchers at Yale School of Medicine, led by Emre Seli, M.D., are developing a fast, non-invasive test to help assess embryo viability for IVF. view more (2009-10-21)
Oldest animal fossils may have been bacteria
The oldest-known animal eggs and embryos, whose first pictures made the cover of Nature in 1998, were so small they looked like bugs - which, it now appears, they may have been. view more (2006-12-21)
Jefferson Researchers Find Nanoparticle Shows Promise in Reducing Radiation Side Effects
With the help of tiny, transparent zebrafish embryos, researchers at the Kimmel Cancer Center at Thomas Jefferson University and Jefferson Medical College are hoping to prove that a microscopic nanoparticle can be part of a "new class of radioprotective agents" that help protect normal tissue from radiation damage just as well as... view more...

Chromosomal problems affect nearly all human embryos
For the first time, scientists have shown that chromosomal abnormalities are present in more than 90% of IVF embryos, even those produced by young, fertile couples. view more (2009-07-01)
SLU scientists have identified the first gene regulating programmed cell death in plant embryos
A research team at the Swedish University of Agricultural Sciences, SLU, has succeeded in isolating a novel gene that regulates cell death in plant embryos. This is a world first. The team consists of scientists from the Department of Plant Biology and Forest Genetics, headed by Peter Bozhkov and Sara von Arnold. The team has discovered... view more... (2004-06-01)
Cells, dyes and videotape: Online scientific methods journal incorporates multimedia
Observing the microscopic mysteries of embryos, cells, and chromosomes is feasible with advanced live imaging technologies. view more (2006-11-06)
Frogs reveal clues about the effects of alcohol during development
Fetal alcohol spectrum disorder (FASD) and Fetal alcohol syndrome (FAS) cause malformations in babies, including facial defects, short stature, and mental and behavioral abnormalities. view more (2009-04-06)
GENETIC SUSCEPTIBILITY TO INFERTILITY (p 1336)
In women, unsuccessful attachment and implantation of fertilised eggs (embryos) to the lining of the womb (endometrium), resulting in infertility, could be influenced by variation of a specific gene, conclude authors in a preliminary study described in a research letter in this week's issue of the Lancet. The failure of embryo implantation is... view more... (2001-04-25)
Embryos tell story of Earth's earliest animals
Much of what scientists learn about the evolution of Earth's first animals will have to be gleaned from spherical embryos fossilized under very specific conditions. view more (2006-03-30)
IVF technique enables pregnancy without multiple births, Stanford researchers find
An in vitro fertilization technique that can avoid multiple births appears to be effective for women older than 35, according to researchers at the Stanford University School of Medicine. view more (2007-10-02)
The Observatory on Bioethics and Law expresses its support for the production of human embryonic stem cells for therapeutic purposes
In response to the controversy that has recently arisen about the use of human embryos for therapeutic and non-reproductive purposes, the Opinion Group of the Observatory on Bioethics and Law of the Barcelona Science Park has drawn up a Declaration on this issue. This document provides information and several view points with the aim to facilitate... view more... (2001-12-17)
Cold Spring Harbor Protocols features methods for visualizing protein dynamics
This month's release of Cold Spring Harbor Protocols highlights methods that permit scientists to observe protein dynamics in chromosomes and embryos. view more (2008-01-03)
High protein diet may be bad for women trying to conceive
A moderately high protein diet could reduce a woman's chances of becoming pregnant, according to new research presented at the 20th annual conference of the European Society of Human Reproduction and Embryology today on Monday 28 June. Researchers from the USA have found that a diet containing 25% protein disrupted the normal genetic imprinting... view more... (2004-06-28)
