New evidence linking high iron levels with shorter lifespan

Hot on the heels of a recently published genomic study correlating blood iron levels with healthy aging, more research is suggesting high systemic iron levels can be linked with reduced life expectancy. The current research does not prove a causal rela… Continue reading New evidence linking high iron levels with shorter lifespan

NASA funds SETI study to scan exoplanets for alien “technosignatures”

Given just how incomprehensibly, unfathomably big the universe is, chances are tiny that Earth is the only planet with life on it. But how would we find others? A new NASA grant has been awarded to aid the search for extraterrestrial intelligence (SETI… Continue reading NASA funds SETI study to scan exoplanets for alien “technosignatures”

Extremophile microbes found thriving half a mile beneath the seafloor

Every time we think we’ve figured out the limits of where life can exist, we discover extremophile organisms thriving under conditions we’d previously ruled out. The latest example comes from studies of rock cores drilled from the floor of the Indian O… Continue reading Extremophile microbes found thriving half a mile beneath the seafloor

Organic molecules on Mars may be evidence of ancient life

Organic compounds have been discovered on Mars in recent years – but how did they get there? A new study examines the different ways that one type in particular, thiophene, may have formed, and intriguingly one of the most plausible scenarios involves … Continue reading Organic molecules on Mars may be evidence of ancient life

Extraterrestrial protein discovered in meteorite for the first time

Scientists have discovered a full, previously-unknown protein inside a meteorite for the first time. Named hemolithin, the new protein contains iron and lithium and may play an important role in seeding life on habitable planets like Earth.Continue Rea… Continue reading Extraterrestrial protein discovered in meteorite for the first time

Analysis of Super-Earth atmosphere reveals potentially-habitable world

Astronomers have analyzed the atmosphere of a nearby exoplanet and found that there are plenty of scenarios where it could have liquid water – and by extension, possibly life – on its surface. This new study adds weight to the idea that habitable exopl… Continue reading Analysis of Super-Earth atmosphere reveals potentially-habitable world

Virtual universes study suggests habitable Earth-like exoplanets are more common than we thought

Earth is – for now – the only place in the universe that we know hosts life, so it makes sense that astronomers focus the search for alien life on worlds that are the most like our own. But just how common are Earth-like planets orbiting at c… Continue reading Virtual universes study suggests habitable Earth-like exoplanets are more common than we thought

New NASA mission launch aims to reduce false-positives in search for life

It’s almost a certainty that we’re not alone in the universe, but so far direct evidence has eluded us. While we have some idea about what kinds of signs to look for on other planets, many of these can also be created under natural processes…. Continue reading New NASA mission launch aims to reduce false-positives in search for life

Life's building blocks spontaneously self-assemble in primordial soup experiment

Researchers have shown that amino acids, the building blocks of life, stack themselves readily under the ...

Exactly how life sprung out of non-living matter is one of biology’s biggest mysteries. But with continued research into our own origin story, it’s starting to seem like life on early Earth was just itching to be born. In new research from Georgia Tech and the Scripps Research Institute, scientists cooked up a “primordial soup” and found that some of the crucial building blocks of life spontaneously stacked themselves in a surprisingly efficient way.
