Bedbugs are blood-sucking parasites in the family Cimicidae. A multinational research team led by University of Sheffield, the University Museum Bergen and Dresden University has compared the DNA of dozens of bedbug species and discovered that bedbugs are 50 million years older than bats — a mammal that scientists had previously believed to be their first host 50-65 million years ago. This digitally-colorized scanning electron micrograph revealed...

Astronomers developed a mosaic of the distant Universe -- called the Hubble Legacy Field -- that documents 16 years of observations from the NASA/ESA Hubble Space Telescope. The image contains nearly 265,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after the Big Bang. The new set of Hubble images, created from nearly 7,500 individual exposures, is the first in a series of Hubble Legacy Field images. Image credit: NASA / ESA / G. Illingworth & D.
