Novel study finds unexpected link between reproductive proteins in humans, invertebrates

A novel study in the scientific journal Molecular Biology and Evolution draws a completely unexpected link between reproductive proteins in humans and proteins involved in fertilization in invertebrates, as well as mating between haploid cells in yeast. Because human and yeast are separated by 1 billion years of evolution, these findings may have important implications for our understanding of the molecular mechanisms underlying sex, and how they originated.

Rubicon Genomics' PicoPlex linear WGA technology proves effective in clinical study

Rubicon Genomics today announced that its PicoPlex linear whole genome amplification technology was proven to be effective in an independent clinical study organized by the European Society for Human Reproduction and Embryology. At a press conference during its 26th Annual Meeting in Rome, ESHRE reported the success of its "groundbreaking proof of principle study" showing that a new approach incorporating PicoPlex could more accurately detect and characterize chromosomal abnormalities in human eggs.

Scientists use PGS method to analyse chromosomal status of eggs

The efficacy of preimplantation genetic screening has been one of the most hotly disputed subjects in assisted reproduction over the past few years. The European Society of Human Reproduction and Embryology PGS Task Force has now shown, in its groundbreaking proof of principle study, that screening of polar bodies (small cells that are the by-product of egg development), is a reliable method to analyse the chromosomal status of an egg.

Whitehead researchers develop new type of genetic screen for human cells

Whitehead researchers have developed a new type of genetic screen for human cells to pinpoint specific genes and proteins used by pathogens, according to their paper in Science.

Embryonic stem cells used to create human sperm

Human sperm have been created using embryonic stem cells for the first time in a scientific development which will lead researchers to a better understanding of the causes of infertility.

Scientists discover function for antisense RNA

Researchers have found that a class of RNA molecules, previously thought to have no function, may in fact protect sex cells from self-destructing. These findings will be published in the November 17 issue of the journal Cell.

New understanding of chromosomal glue

Researchers have a new understanding of the process cells use to ensure that sperm and eggs begin life with exactly one copy of each chromosome - a process that must be exquisitely regulated to prevent problems such as miscarriages and mental retardation.

Researchers have uncovered evidence of sexual reproduction in a single-celled organism long thought to reproduce asexually

The finding by John M. Logsdon, Jr., assistant professor in the UI College of Liberal Arts and Sciences Department of Biological Sciences and the Roy J. Carver Center for Comparative Genomics, and colleagues from the UI and Roanoke College (Virginia), provides the first clear evidence that meiosis arose very early in eukaryotic evolution, bringing science one step closer to understanding the mystery of sexual evolution.

A higher male susceptibility to disease has helped shape the evolution of social insect behavior

A pair of scientists has proposed a new model for behavioral development among social insects, suggesting that a higher male susceptibility to disease has helped shape the evolution of the insects' behavior.
