Scientists find possible cause for IVF implantation failure
Researchers have identified a biological process that may cause the failure of embryos to attach to the uterus wall during IVF, raising the possibility of future treatments...

microRNA (miRNA)
MicroRNAs are small, non-coding RNA molecules that regulate gene expression by suppressing the RNA pathway that translates genes into protein. They act like 'master switches', having the ability to control the activity of multiple genes.

Trauma can be passed down through sperm
Stress in early life can alter the production of small sections of the genetic material RNA in the sperm of mice, affecting behaviour not only in the mice themselves but also in their offspring, research suggests...
'Gene signature' predicts chemotherapy survival
Scientists have identified an eight-gene 'signature' that can predict patients' response to chemotherapy...
Scientists discover why regular sex prior to conception reduces pregnancy complications
A man may contribute more than just sperm to the process of conception, research suggests...
Gene variant leads to six-fold increase in risk for certain brain tumours
A single-letter change in one gene may considerably increase a person's risk of developing particular forms of brain cancer, say researchers...
Heart scar tissue repaired without stem cells
Scar tissue formed after a heart attack could be repaired without the use of stem cells, according to US scientists...
You are what you eat - study suggests veg can alter your genes
Small fragments of genetic material from vegetables we eat could be altering our genes, according to a study carried out by scientists in China...
'Man flu' - do women just have stronger immune systems?
Genetic differences between men and women could mean that women are better at resisting certain infections and diseases than men, a new study suggests. The second X chromosome in women gives them an immunological advantage over men, possibly giving credence to man's perceived susceptibility to 'man-flu'....
Brain cells made from skin
US researchers have successfully converted human skin cells directly into brain nerve cells, skipping an intermediate stem cell stage. The new technique has the potential to aid research into neurodegenerative disorders of the brain, such as Parkinson's and Alzheimer's....
New method '100-fold' better at stem cell reprogramming
A novel and more efficient method for generating induced pluripotent stem cells (iPSCs) from adult cells using small RNA molecules has been discovered by researchers at the University of Pennsylvania School of Medicine in the USA...
