Emory researcher provides overview on 'CVD and PCOS' in APS conference

Sarah Berga, MD, former Chair of the Department of Gynecology and Obstetrics at the Emory University School of Medicine, is a researcher whose work focuses on understanding the impact of metabolic and psychological stresses on the reproductive system and as a cause of infertility, as well as on PCOS. She will provide an overview of her team's work in a presentation entitled, "CVD and PCOS." Her remarks are part of the Physiology of Cardiovascular Disease: Gender Disparities conference, October 12 at the University of Mississippi in Jackson.

Novel link between cell surface sugars, Darwinian sexual selection, and immune function

Researchers at the University of California, San Diego School of Medicine say that losing the ability to make a particular kind of sugar molecule boosted disease protection in early hominids, and may have directed the evolutionary emergence of our ancestors, the genus Homo.

New technique could give a preview of which eggs are likely to make the most viable embryos

Given the stakes of in vitro fertilization, prospective parents and their doctors need the best information they can get about the eggs they will extract, attempt to fertilize, and implant. New research at Brown University and Women & Infants Hospital of Rhode Island has found a way to see which genes each egg cell is expressing without harming it.

Researchers identify unusual genomic architecture linked with very severe forms of disease

When cells divide normally, DNA gets copied perfectly and distributed among the daughter cells with an even hand. Occasionally though, DNA breaks during division and is rearranged, resulting in duplications or deletions of important parts of the blueprint.

Two Smithsonian scientists win PECASE award for innovative research, scientific leadership

Two scientists at the Smithsonian Institution have been honored with the Presidential Early Career Award for Scientists and Engineers for their innovative research and scientific leadership. It is the highest honor bestowed by the U.S. government on science and engineering professionals in the early stages of their independent research careers.

A Daddy’s heart is healthier: Study

A new study shows that fathers are less likely to die of heart disease than men who’ve never had kids. This raises questions about a possible biological link between male infertility and overall health. Other recent studies have found a connection between testicular and prostate cancer and infertility.

Researchers analyse effects of BPA in an in-vitro culture of ovaries

Researchers at Universitat Aut-noma de Barcelona, in collaboration with the Vall d'Hebron Hospital Fetal Tissue Bank, the Department of Gynaecology and the Research Unit of Paediatric Endocrinology, analysed the effects of Bisphenol A (BPA), a polymer widely used to manufacture plastics, in an in vitro culture of ovaries.

Researchers show how the body rids itself of damage when needed to reproduce and create new life

Although the body is constantly replacing cells and cell constituents, damage and imperfections accumulate over time. Cleanup efforts are saved for when it really matters. Researchers from the University of Gothenburg, Sweden, are able to show how the body rids itself of damage when it is time to reproduce and create new life.

Woman with two wombs gives birth to miracle twins

A Florida woman with a rare medical condition has delivered twins -- one from each of her two uteruses. The 24-year-old mother, Andreea Barbosa and her husband, Miguel, conceived the twins without reproductive medicine. Nathan and Natalie Barbosa were born Sept. 15 at Morton Plant Hospital in Clearwater. They join 2-year-old sister, Izabella.

Scientists uncover one of the benefits of non-monogamous relationships

It's all about the grandkids! That's what a team led by an Indiana University biologist has learned about promiscuous female birds and why they mate outside their social pair.

Dad's stress can affect unborn children

Does Dad's stress affect his unborn children? According to the results of a new study in Elsevier's Biological Psychiatry, it seems the answer may be "yes, but it's complicated".

Stanford method identifies essential regions of Caulobacter's genome

A team at the Stanford University School of Medicine has cataloged, down to the letter, exactly what parts of the genetic code are essential for survival in one bacterial species, Caulobacter crescentus.

Tiny molecule could bind to B cell EB12 receptor and prevent cancer

Infection with Epstein Barr means that the B cells, which are the primary memory cells of the immune system, are hi-jacked. When the virus has penetrated, researchers observe an excess of a special bio-antenna, a receptor known as EB12, suddenly sprouting from the surface of the B cells. But why they do so remains a mystery.

UC Riverside research could help prevent crop loss, pest outbreaks

New research by scientists at the University of California, Riverside shows that evolution - genetic changes in populations over time - can occur so rapidly in organisms that its impact on population numbers and other aspects of biology can be seen within just a few generations.

Young stressed females can impair future offspring, also improve resilience

The study found that stress experienced by young female rats can impair their future offspring, but can also improve resilience. The study also showed that providing the young stressed females with an enriched environment, can indeed ameliorate some of the effects.
