Penn Researchers Identify First Sex Chromosome Gene Involved in Meiosis and Male Infertility
A team of scientists led by University of Pennsylvania veterinary researchers have identified a gene, TEX11, located on the X chromosome, which when disrupted in mice renders the males sterile and reduces female fecundity. This is the first study of the genetic causes of infertility that links a... view more (2008-03-17)

Link between assisted reproduction techniques and genetic disruption
Evidence that assisted reproduction techniques may carry a risk of genetic 'imprinting disorders' in the resulting babies, emerges in a study published in the Journal of Medical Genetics. To assess the likely risk of genetic disruption, geneticists from the University of Birmingham and the West... view more (2003-01-14)

Scientists at Low Temperature Laboratory planning to model a black hole
Academy Professor Matti Krusius and Antti Finne, M.Sc. (Eng.), were invited to a recent science breakfast, hosted by the Academy of Finland, to talk about their ongoing work to produce a first-ever laboratory simulation of a black hole. A black hole is created as a result of the most extreme... view more (2003-04-16)

Study shows that genetic quality of sperm deteriorates as men age
New research indicates that the genetic quality of sperm worsens as men get older, increasing a man's risk of being infertile, fathering unsuccessful pregnancies and passing along dwarfism and possibly other genetic diseases to his children.   view more (2006-06-06)

Neurons find their place in the developing nervous system with the help of a sticky molecule
The brain, that exquisite network of billions of communicating cells, starts to take form with the genesis of nerve cells. Most newborn nerve cells, also called neurons, must travel from their birthplace to the position they will occupy in the adult brain.   view more (2006-04-26)

Researchers figure out how hearts fail
Researchers have determined how metabolic pathways differ between healthy and failing hearts. Normally, a heart derives its energy from a balance of fatty acids and carbohydrates, specifically glucose.   view more (2005-07-25)

Girls fare better than boys following heart surgery
A recent study published in Critical Care examined the role of molecules, known as cytokines, in the recovery of children following heart surgery. The study found that girls had higher levels of cytokine IL-10, which meant that they recovered more easily from their operations than boys. In order... view more (2002-01-16)

Proteins are key to cell death in heart disease, stroke and degenerative conditions
Researchers at Yale School of Medicine have gained deeper understanding of two members of a family of proteins called caspases that play a key role in promoting apoptosis, a process in which the cell responds to external signals by essentially committing suicide.   view more (2006-02-23)

Safe vaccine to combat herpes infections
The unpleasant and painful sores, and infection of newborn babies caused by the genital herpes virus could soon be a thing of the past according to Dr Julian Hickling, who is presenting results from Xenova Research Ltd today, Tuesday 8 April 2003, to the Society for General Microbiology's Spring... view more (2003-04-02)

Do high dietary intakes of trans fats really promote cardiovascular disease?
From his assessment of the studies, Dr John Stanley says the conclusion that trans fatty acids promote cardiovascular disease is premature for the following reasons. First, although prospective cohort studies show an association with cardiovascular disease, trans fatty acids are estimated rather... view more (1999-11-18)

New technique improves purity of medicines
Dutch researcher Roelof Mol has investigated possibilities for more accurately determining the composition of medicines. He came up with a combination of two techniques that were previously considered to be incompatible: the separation technique electrokinetic chromatography (EKC) and the detection... view more (2007-10-25)

Workman Lab characterizes novel regulator of chromosome function
The Stowers Institute's Workman Lab has shed new light on a novel histone acetyltransferase protein complex called ATAC. Acetyltransferases are enzymes that introduce a new acetyl functional group into histone proteins, a process by which all chromosome functions are controlled.   view more (2008-03-11)

Closing holes in heart important treatment for young stroke patients, study says
Placement of devices to close holes in the heart is a successful treatment for young stroke patients, finds a study involving three medical centers.   view more (2006-05-18)

Sensorial evaluation of the freshness of fish
AZTI has drawn up some 40 tables for freshness specific for the most important commercial species in southern Europe, including fish and shellfish. The sensorial method, known as QIM (Quality Index Method) and introduced into Europe some years ago, is being applied to a greater number of species,... view more (2005-04-18)

EURYI project to understand how the brain wires during embryogenesis
One of the great questions of neurobiology, how the brain is built up during embryonic development, could be resolved by a young French scientist in an award winning project organised by the European Science Foundation (ESF) and the European Heads of Research Councils (EuroHORCS).   view more (2007-09-24)

Swimming pool chlorine risk to pregnant women
Research by Dr Mark Nieuwenhuijsen published in the journal Occupational and Environmental Medicine today (4 April) highlights an area of potential risk to pregnant women through exposure to the by-products of chlorination in swimming pools. The following statement clarifies the potential risk:... view more (2002-04-04)

Rong Li Lab probes mechanism of asymmetry in meiotic cell division
The Stowers Institute's Rong Li Lab has characterized a mechanism that allows for asymmetrical cell division during meiosis in oocytes. By tracking chromosome movement in live mouse oocytes, the team discovered that chromosomes can recruit to their vicinity a protein called formin-2.   view more (2008-10-08)
