It turns out that hydraulic fracturing, known commonly as fracking, may be triggering earthquakes. Scientists have found that fracking caused a series of small earthquakes in 2013 on a previously unmapped fault in Harrison County, Ohio.
Archaeologists have uncovered some bizarre fossils that may just be related to us. The 500-million-year-old blind water creatures, known was vetulicolians, may be in the same group that includes vertebrate animals, such as humans.
Crocodiles have been around for millions of years. Now, scientists have taken a closer look at the ancient crocodiles that once roamed the world's seas and have found that they developed in similar ways to their modern-day relatives.
Three endangered Sumatran tiger cubs were born last Wednesday at Point Defiance Zoo & Aquarium.
Not all kangaroo families liked to hop. Scientists have discovered an ancient kangaroo that lived 100,000 years ago that walked on two legs like a human rather than hopping or lumbering away on all fours.
It's National Fossil Day, which means that we're taking a closer look at these ancient remnants of a time long past.
How does a bird deal with turbulence? The answer may be in their collapsible wings. By placing a "black box" flight recording on an eagle's back, scientists have found how birds manage to deal with turbulent winds.
Scientists may have just pinned down the worst drought in North American history. They've examined the last 1,000 years and found that the drought of 1934 was the driest and most widespread of the last millennium.
Scientists have found that four urban sections of the Sand Andreas Fault system in Northern California have stored enough energy to produce major earthquakes.
What if all of the compasses in the world suddenly pointed south instead of north? Earth's magnetic field periodically flips over time and now, scientists have announced that it's possible for this change to occur over the course of a human lifetime--in less than 100 years.
Archaeologists have made a surprising discovery. They've unearthed the oldest known lamprey fossil to day. The finding could shed light on the ancient origins of the eel-like, blood-sucking lamprey and, in turn, reveal a bit more about the evolution of other animals.
New York City is known for its rats. They can be found in subways, skirting trash bags and skirting building corners. Now, though, scientists have taken a closer look at these rats and have identified bacterial pathogens that these rats may be carrying.
