Can We Please Have More Diverse Dragon Designs Like These?

We love dragons, but sometimes it feels like if you've seen one dragon, you've seen them all—especially on-screen. These designs by Vincent Coviello are a dragon's breath of fresh air, adding a bit of variety to these terrible beasts. » 5/07/14 3:20pm 5/07/14 3:20pm

Curiosity finds no sign of methane on Mars — but does that mean there's…

NASA's Curiosity rover has been sniffing out Mars' atmosphere in search of methane. Methane is a precursor chemical for life. It's also thought that 95% of the methane in Earth's atmosphere is organismal in origin. Methane on the Red Planet would therefore be suggestive of past or present life. » 11/02/12 12:58pm 11/02/12 12:58pm

What secrets lie within the Caves of Mars?

Back in 1954, Jerome Bixby wrote a fantastic story called "The Holes Around Mars". It was all about the discovery of series of weird holes discovered in the surface of Mars, holes seemingly punched through rocks and hills and mountains. We wouldn't dream of spoiling the ending (you can read it here.) But it's become… » 7/20/12 4:00pm 7/20/12 4:00pm

The Moons of Mars may be the first place we find extraterrestrial life

Was there ever life on Mars? In fact, could there still be microbes living on Mars now? It's still a distinct possibility. But given the difficulties involved in sending people and specialized equipment to Mars to look for samples, we could be waiting decades to find out. So it's a good thing there's a ready… » 7/02/12 1:31pm 7/02/12 1:31pm

XNA is synthetic DNA that's stronger than the real thing

New research has brought us closer than ever to synthesizing entirely new forms of life. An international team of researchers has shown that artificial nucleic acids - called "XNAs" - can replicate and evolve, just like DNA and RNA. » 4/19/12 12:38pm 4/19/12 12:38pm

Oxygen discovered around Saturn's icy moon

The moons of Saturn and Jupiter are just getting more and more intriguing. While many of those far-flung satellites might contain liquid oceans, a new report indicates that Dione, one of Saturn's icy moons, is surrounded by a thin layer of oxygen. » 3/03/12 9:00am 3/03/12 9:00am

Why Silicon-based Aliens Would Rather Eat Our Cities Than Us

What would non-carbon-based life really be like? What would it want from us? Bruce Dorminey, science journalist and author of "Distant Wanderers: The Search for Planets Beyond the Solar System," interviews NASA astrochemist Max Bernstein about the possibility of silicon-based life, in an article from Universe Today. » 12/05/11 2:30pm 12/05/11 2:30pm

How to Create a Scientifically Plausible Alien Life Form

With a possible two billion Earth-like planets in our galaxy alone, the chances of extraterrestrial life are looking better and better. What will these creatures, shaped by another world, look like? It's up to science fiction creators to imagine them. » 3/23/11 2:00pm 3/23/11 2:00pm

Titan's atmosphere is ideal for creating life

Evidence of life on Saturn's moon Titan just keeps piling up, and now we can add experimental proof to the list. Recreating the satellite's nitrogen-rich atmosphere and bombarding it with UV rays produces the organic molecules that lead to life. » 6/30/10 7:30am 6/30/10 7:30am

We'll Only Find Extraterrestrial Life If We Know What We're Looking For

Our probes and landers still look for life "as we know it." But we're already aware that even terrestrial life goes beyond what we once considered possible. We should use that experience, or we may literally step on alien life. » 4/28/10 2:14pm 4/28/10 2:14pm

Life Imitates V: The Vatican Welcomes Extraterrestrial Intelligences

In case you thought V's storyline, in which the Catholic Church embraces the alien visitors as "God's creatures," was too far fetched, the Vatican held a conference on exo-biology this week. Which occasioned this awesome image from the Telegraph newspaper. » 11/10/09 8:00pm 11/10/09 8:00pm

DNA Proves Groovy Hopping Fish Known As "Psychedelica" Is A New Species

They're bizarre-looking yet reclusive. They hop more than they swim. And they have human-style eyes in the front of their head instead of on the sides. So, yes, Psychedelica really is a new fish species. » 2/26/09 11:35am 2/26/09 11:35am

The Only Alien Aliens In SF Are From Books

Most aliens in science fiction are too similar to humans, complains novelist Daryl Gregory. In response, Science Fiction Biology tries to come up with a list of non-humanish aliens... and they're all from books. [Science Fiction Biology] » 1/24/08 10:40am 1/24/08 10:40am
