DNA may help scientists find ‘dark matter,’ the glue that binds galaxies

That wonder molecule of life on Earth, DNA, is now being enlisted in the search for an exotic species zooming through the cosmos: dark matter.

As far back as the 1930s, astronomers watching distant galaxies saw that something was missing: There were not enough stars to account for the heavy gravity needed to whirl galaxies so quickly or smash them together so swiftly.

Scientists cant see dark matter particles, but they think they may be able to capture evidence of them when they ping into other tiny things, like balls on a pool table. Previous ideas for capturing these interactions required huge spaces, but a group of scientists has come up with the idea for a detector that would fit on a large coffee table.
