Identical twins may have more differences than meet the eye
Identical twins lose some fundamental similarities as they grow older, a new study reports. Researchers report in this week's Proceedings of the National Academy of Sciences that these differences may stem from changes in the epigeno...Twin molecular scissors link creation of microRNAs with gene-silencing
One of the body's primary strategies for regulating its genome is a kind of targeted gene silencing orchestrated by small molecules called microRNAs, or miRNAs. First observed only a few years ago, these molecules appear to inactivate messenger RNA, itself responsible for translating genes into proteins. Scientists have been eager to know more about miRNAs, clearly important players on the geneti...UCLA scientists discover immune response to HIV differs, even in identical twins
In findings illustrating the difficulty of developing an AIDS vaccine, UCLA AIDS Institute researchers report the immune systems in two HIV-positive identical twins responded to the infection in different ways. ), the findings show that the body's defenses against the v...How can identical twins be genetically different?
They sleep together, eat together, and most people find it impossible to tell them apart. Identical twins who grow up together share just about everything, including their genes. But sometimes only one twin will have health problems when genetics predicts both of them should. Scientists at the University of Michigan Medical School are just beginning to understand how two people who are so...Nutrition a major factor in rise in twin pregnancies
The commonly held view that IVF is the only culprit in the steady increase in the numbers of twins born over the past thirty years was challenged by a scientist speaking at the 22nd annual conference of the European Society of Human Reproduction and Embryology in Prague, Czech Republic, Wednesday 21 June 2006. Professor Robert Jansen, Medical Director of Sydney IVF, Sydney, Australia, said that...An Assessment of the Eppendorf twin.tec plate performance in PCR* applications
M. Arun Kumar, PhD, and Vincent Prezioso, PhD, Brinkmann BioSystems Laboratory To evaluate the performances of Eppendorf 96-well twin.tec PCR plates, we carried out PCR reactions with twin.tec plates and PCR microplates from another commercial mi...Chippewa Valley reps hope to score at Twin Cities tradeshow

According to a research in cancer, women with an identical twin who develop breast cancer have three times the average risk of also developing the disease. Professor Julian Peto, a scientist for Cancer Research UK, has been analyzing data from US female twins. These were identical and non-identical twins where one twin already had breast cancer.// The twins without cancer were then follow...Identical twin breast cancer risk
Research has found out that women diagnosed with breast cancer have an identical twin. Previous research, from the charity Cancer Research, suggests that, before the menopause, if one identical twin has breast cancer, their sister has a much increased risk of also getting the disease.// Now researchers at the University of Southern California show that the risk persists after the menopaus...Marijuana 'gateway' theory strengthened by study of twins
A new study of 311 sets of same-sex twins in which only one twin had smoked marijuana before age 17 has bolstered the fiercely debated "gateway theory" that pot can lead to harder drugs. The study included 136 sets of identical twins who shared the same genetic makeup and all the participants were 30 years of age, on an average, when they were asked about their teenage drug use. The resea...Twins Less Prone to Suicide Than Others
Twins are less likely to commit suicide than other people, scientists said on Friday. Researchers in Denmark looked at the records of more than 20,000 same-sex twins who died between 1943 and 1993 and compared their rates of suicide with the wider population. They found that the suicide rate was lower for twins, regardless of their sex.// The findings came as a surprise because other s...
