Step towards understanding cell mutations that cause a variety of human diseases

A step towards understanding cell mutations that cause a variety of human diseases, particularly in children - including that which brings about premature aging and early death - has been taken by researchers at the Hebrew University of Jerusalem Silberman Institute of Life Sciences and the John Hopkins University School of Medicine.

Australian stem cell discovery hailed as a major medical and scientific development

Monash Institute of Medical Research (MIMR) senior scientist Dr Caroline Gargett's discovery of adult stem cells in the uterus that can be grown into bone, muscle, fat and cartilage, has been hailed as a major medical and scientific development by international reproduction experts.

Fertility drugs may be ineffective for women who lack a gene called the estrogen receptor beta

"What we found is that the beta estrogen receptor plays a role in moving the egg outside the ovary so it can be fertilized," said Kenneth Korach, Ph.D., Laboratory Chief at the National Institute of Environmental Health Sciences (NIEHS) where the research was conducted. "We never knew before what function this receptor played in reproduction."

Cigarette smoke stops transport of freshly ovulated hamster eggs

Eggs of female hamsters are significantly less likely to be transported by the oviduct when the eggs or the oviduct have been exposed to cigarette smoke, and this could result in disruption of fertilization and pregnancy, according to reproductive scientists at the University of California, Riverside.

Our thirst for novelty begins in the eye itself

Researchers at Harvard University have found evidence that the retina actively seeks novel features in the visual environment, dynamically adjusting its processing in order to seek the unusual while ignoring the commonplace. The scientists report in this week's issue of the journal Nature on their finding that this principle of novelty-detection operates in many visual environments.

Chemicals found in everyday products and food have subtle but potentially damaging effects on sperm fertility

Professor Lynn Fraser told the 21st annual conference of the European Society of Human Reproduction and Embryology today (Wednesday), that her previous research had shown that certain chemicals known to mimic the female sex hormone, oestrogen, could individually affect the correct functioning of mouse sperm, but now her new research showed that when the chemicals were combined they had an even stronger effect.
