2024年8月2日 · The landmark Twins Study brought ten research teams around the country together to observe what physiological, molecular, and cognitive changes could happen to a human from exposure to spaceflight. This was accomplished by comparing retired astronaut Scott Kelly while he was in space, to his identical twin brother, retired astronaut Mark Kelly ...

2014年8月11日 · WASHINGTON — Jim Lewis and Jim Springer were identical twins raised apart from the age of 4 weeks. When the twins were finally reunited at the age of 39 in 1979, they discovered they both...

2023年9月27日 · The landmark Twins Study helped scientists better understand the impacts of spaceflight on a human body through the study of identical twins. Retired astronaut Scott Kelly spent one year in low-Earth orbit aboard the International Space Station while retired astronaut Mark Kelly, his identical twin, remained on Earth. The twins’ genetic ...

Twin studies are studies conducted on identical or fraternal twins. They aim to reveal the importance of environmental and genetic influences for traits, phenotypes, and disorders. Twin research is considered a key tool in behavioral genetics and in …

2019年4月11日 · NASA recognizes the Twins Study as the first study of its kind to compare molecular profiles of identical twin astronauts, and a methodology to integrate research from the ten teams was established.

2007年10月25日 · Unknowingly, Bernstein and Schein had been part of a secret research project in the 1960s and '70s that separated identical twins as infants and followed their development in a one-of-a-kind...

Briana Mezuk and colleagues recruited some 50 pairs of identical twins from the Mid-Atlantic Twin Registry, the largest such registry in the US. The researchers found that studying twins...

2016年3月4日 · Studies of identical and fraternal twins have long been used to untangle the influences of genes and the environment on particular traits. Identical twins share all of their genes, while...

2018年5月15日 · Identical twins (also known as monozygotic twins) come from a single egg that splits in two, and share 100 percent of their genes. Neither Hoffman twin tested positive for BRCA gene...

2019年5月3日 · Researchers put both men—who like all identical twins shared the same genetic makeup at birth—through the same battery of biomedical tests to gauge how the human body responds to life in space. The good news for the future of space travel is that the results indicated that health is “mostly sustained” during a prolonged stay in space.
