DNA of people with depression, trauma is biologically older than healthy individuals

This effect was greater in people who have had childhood trauma, such as violence, neglect or sexual abuse, who show a biological age around a year older than their actual age. This work is presented at the ECNP conference in Barcelona. There is increasing evidence that serious depression and trauma is associated with shorter life-spans. […]

There is no ‘gay gene,’ finds major study

Instead, a person’s attraction to those of the same sex is shaped by a complex mix of genetic and environmental influences, similar to what’s seen in most other human traits, researchers report. “This is a natural and normal part of variation in our species,” said researcher Ben Neale, director of genetics with the Stanley Center […]

Male pregnancy could be a reality with a new medical procedure

Male pregnancy could be a reality with a new medical procedure

Using ordinary skin cells, scientists were able to create artificial sperm and eggs in the laboratory. The process, tested in animal subjects, appeared effective in growing a baby with genes from parents that donated skin cells. This might help male pregnancy become a reality. The induced pluripotent stem cells (iPSCs) were first reported effective to […]

Will you have a long lifespan? Your family’s genes provide answers

The study was published online on January 07 in the journal Nature Communications. Using databases at the University of Utah and in the Dutch province of Zeeland, investigators analysed the genealogies of nearly 315,000 people from over 20,000 families dating back to 1740. “We observed, the more long-lived relatives you have, the lower your risk […]

Recurrent miscarriage linked to faulty sperm, reveal researchers

The early-stage study, from scientists at Imperial College London, investigated the sperm quality of 50 men whose partners had suffered three or more consecutive miscarriages. The research, published in the journal Clinical Chemistry, revealed that, compared to men whose partners had not experienced miscarriages, the sperm of those involved in the study had higher levels […]

Acne study reveals genes for hair follicles are partly to blame

A large genetic study of people with acne could pave the way for new treatments. The study looked at the DNA of 27,000 people, including over 5000 with severe acne, and identified genetic differences that were more common in people with the condition. It found that many of these genetic variants influenced the formation of […]
