sciencehabit shared this article from Science magazine:Dark matter, the mysterious substance that makes up most of the mass of the universe, has proved notoriously hard to detect. But scientists have now proposed a surprising new sensor: human flesh. The idea boils down to this: If a certain type of dark matter particle existed, it would occasionally kill people, passing through them like a bullet. Because no one has died from unexplained gunshot-like wounds, this type of dark matter does not exist, according to a new study... [It's title' "Death by Dark Matter."] This experiment doesn't rule out heavy macro dark matter altogether, says Robert Scherrer, a co-author and theoretical physicist at Vanderbilt University. It merely eliminates a certain range of them. Heavier macro dark matter would not occur frequently enough to measure, notes Katherine Freese, a theoretical physicist at the University of Michigan, and other forms wouldn't kill people. "There is probably still room for very heavy dark matter," says Paolo Gorla, a particle physicist at Italy's underground Gran Sasso National Laboratory, who is not involved with the study.Read more of this story at Slashdot.
