Dan Werthimer, a Search For Extraterrestrial Intelligence (SETI) researcher at the University of Berkeley, California and a coauthor on the research project which first spotted the signals, told Live Science that the narrow-band radio signals he and his fellow researchers found "are from [human] radio interference, and not from extraterrestrials."

But what is the history of arsenic poisoning, and how does it kill?

It's a hallmark of our species — so much so that scientists once speculated that the capacity for language was the key difference between us and other animals. And we've been wondering about each other's thoughts for as long as we could talk about them. "The 'penny for your thoughts' kind of question is, I think, as old as humanity," Russell Hurlburt, a research psychologist at the University of Nevada, Las Vegas who studies how people formulate thoughts, told Live Science. But how do scientists study the relationship between thought and language? And is it possible to think without words?

Typically, after receiving a transplant, organ recipients must take immunosuppressive drugs for the rest of their lives, in order to prevent the immune system from rejecting the organ. This places organ recipients at an increased risk for infections and cancer, and even then, the immunosuppressants don't eliminate the risk that the body will eventually reject the organ anyway.

The star — located about 26,000 light-years from Earth near the dense and dusty galactic center — is about 32 times as massive as the sun and sits within an enormous disk of swirling gas, known as a "protostellar disk." (The disk itself measures about 4,000 astronomical units wide — or 4,000 times the distance between Earth and the sun).

The enormous cosmic entity is 3 billion times more massive than the sun and swallows up an Earth-size chunk of matter every second. The new supermassive black hole, known as J1144, is around 500 times as Sagittarius A*, the supermassive black hole at the heart of the Milky Way, which was recently photographed for the first time. A ring of superhot plasma around the enormous void also emits around 7,000 times more light than our entire galaxy.

What killed them?]( (Shutterstock) More than 500 of the world's smallest penguins have mysteriously washed up dead on beaches across New Zealand over the past couple of months. Experts aren't exactly sure what has been killing off such a large number of the adorable seabirds, but they suspect that climate change may have played a role.
