The Sun Is Coming!

Earth got off relatively easy last week after being hit by the biggest blast of solar radiation since 2005—but we may not be so lucky next time. Last week’s coronal mass ejection, in which a solar flare whipped an arc of magnetic particles toward Earth at 4 million mph, led some airlines to reroute flights away from the poles, where […]

The vital job of ‘junk’ DNA

Since the late 1990s, when they began decoding the human genome, scientists have believed that 98 percent of DNA is “junk,” with no function. But new research shows that most of this genetic material serves as switches that turn genes on or off, which could explain why some people predisposed to certain diseases get them, while others don’t. Our genome […]

New images of a galaxy located 60 million light-years from Earth have revealed that / it’s a cannibal. Composite pictures from the La Silla Observatory in Chile show that the NGC 1316 galaxy is strewn with dust N and small star clusters, space debris that astronomers say is the remains of another galaxy that was swallowed up by the black […]

Starburst galaxy sheds light on longstanding cosmic mystery

Scientists from the University of Delaware’s Bartol Research Institute in the Department of Physics and Astronomy have discovered very-high-energy gamma rays in the Cigar Galaxy (M82), a bright galaxy filled with exploding stars 12 million light years from Earth. The gamma rays observed by the team have energies more than a trillion times higher than the energy of visible light […]

Native Americans’ Siberian Roots

Native Americans’ Siberian Roots have been documented in recent research. The skeleton of a girl who died over 12k years ago has provided DNA confirming evidence that Native Americans must have originally migrated from Siberia.   Analysis of the DNA showed a genetic marker commonly found in today’s Native American population. Human geneticist Chris Tyler says, “From archaeological, genetic, and […]
