NASA has released preliminary results from the genetic study of twin brothers Scott and Mark Kelly:

The first results from NASA's Year in Space brothers are in, and show glimpses of how stressful a trip to Mars could be for the human body. Astronaut Scott Kelly captivated minds when he departed Earth in March 2015, bound for a yearlong stay at the International Space Station. Part of the excitement surrounded an experiment with his twin brother Mark Kelly, a retired astronaut who stayed on Terra Firma. At this week's NASA Human Research Program workshop, researchers revealed that the trip created contrasts in their genes' regular activities.

[...] Genomic data was taken before, during and after Scott Kelly launched to the ISS aboard a Soyuz rocket in Mar. 2015. He returned in 2016, after spending 340 consecutive days in outer space. A future mission to Mars would take at least 9 months, but a round trip would be 500 days. Scott's gene expression and DNA methylation fell back to their pre-flight status shortly after he returned from the space station. What this means exactly is still unclear, but scientists are eager to learn more.

    Josef Mengele, trained as a physician, evaded the Mosad and drowned while swimming at age 67.
    He was known as The Angel of Death because he wore his white lab coat as he directed arrivals at the Auschwitz death camp to the right or the left (continued life or immediate death).

    Both of his degrees were later rescinded by the issuing universities.
    [...]
    [American author Robert Jay] Lifton describes Mengele as sadistic, lacking empathy, and extremely antisemitic
    [...]
    Experiments performed by Mengele on twins included unnecessary amputation of limbs, intentionally infecting one twin with typhus or other diseases, and transfusing the blood of one twin into the other. Many of the victims died while undergoing these procedures. After an experiment was over, the twins were sometimes killed and their bodies dissected.
    [...]
    Dr. Miklós Nyiszli, a Hungarian Jewish pathologist who arrived in Auschwitz on 29 May 1944 [...] recalled one occasion where Mengele personally killed fourteen twins in one night via a chloroform injection to the heart. If one twin died of disease, Mengele killed the other so that comparative [postmortem] reports could be prepared.
    [...]
    [His] twins studies may also have been motivated by a desire to improve the reproduction rate of the German race by improving the chances of racially desirable people having twins.
