A University of Carolina study monitoring 1200 newborns from the ‘Isle of Wight cohort’ found that first borns were more likely to carry a gene variant which raised their risk of developing an allergy before the age of 10. The study suggested that a first born experienced different conditions in the uterus from subsequent siblings.

University of Minnesota researchers looking to answer the question ‘why does ultraviolet light induce skin cancer?’ believe they have found how sun-induced skin cancer starts. They found the cancer starts in receptor molecules or molecular “hooks” on the outer surface of cells that also pull cannabinoid compounds found in marijuana out […]
Cambridge University researchers have identified a small molecule that appears to play a major role in making our body clocks tick. Studies in mice have shown cAMP - a common signalling molecule - is involved in keeping the body clock “rhythms” going (circadian rhythms).
The body’s internal clock is a highly sensitive mechanism able to anticipate changes in the […]
A team from The University of Alabama (UAB) have found that among billions of HIV variants only a few lead to sexual transmission.
George M. Shaw Professor in the UAB departments of Medicine and Microbiology and senior author on the report, said the research sheds new light on potential vulnerabilities in the virus at a time when […]
Researchers have found marked genetic differences between brains of men who committed suicide and the brains of men who did not. Of those individuals studied, all had been victims of child abuse.
Even though the genetic sequence was the same in the suicide and non-suicide brains, researchers at the McGill University, Montreal, Quebec, led by Moshe Szyfa, […]

Researchers from St George’s Hospital, University of London have identified a biological basis for 7 different genetic types of Chronic Fatigue Syndrome (CFS).
The St George’s study looked at 55 patients from the US and UK with the condition, and carried out a genetic analysis of them and 75 healthy blood donors.
It identified the seven […]
Scientists from Imperial College London and other international institutions have discovered a gene sequence that is associated with a 2cm expansion in waist circumference, a 2kg gain in weight, and a tendency to become resistant to insulin, which can lead to type 2 diabetes. The sequence is found in 50% of the UK population.
The study shows that the […]
Osteoporosis

An extensive genome-wide search has been undertaken to find the genes linked to osteoporosis and fracture. Five regions of interest have been identified that appear to warrant further scientific investigation.
The Garvan Institute for Medical Research collaborated with the Icelandic genetics company, deCode, in a project that looked at 1500 women from Garvan’s Dubbo Osteoporosis […]

Scientists believe they have identified a gene that may be able to limit the growth of breast cancer tumors.
The US National Cancer Institute, led by geneticist Kent Hunter found in tests on mice that tumors containing the bromodomain 4 or Brd4 gene ended up 10 times smaller than ones that did […]
KQED Public Broadcasting in San Francisco recently did a radio story about the UC San Francisco Canine Behavioral Genetics Project run in collaboration with the University of Pennsylvania. The aims of the project are:
1. To explore the relationship between genes and behavior, both normal and abnormal, in domestic dogs.
2. To assess the amount and nature […]
