Hydrothermal vents could explain chemical precursors to life

Roy Price first heard about the hydrothermal vents in New Caledonia's Bay of Prony a decade ago. Being a scuba diver and a geologist, he was fascinated by the pictures of a 38-meter-high calcite "chimney" that had precipitated ...

The energetic origins of life

(Phys.org) —Imagination is perhaps the most powerful tool we have for creating the future. The same might be said when it comes to creating the past, especially as it pertains to origin of life. Under what conditions did ...

Delving into the spread of marine life

A paper by Dr. Masako Nakamura of the OIST Marine Biophysics Unit on the ecology of one of deep-sea limpets called Lepetodrilus nux has been published in the Marine Ecology Progress Series. These deep-sea limpets are conches ...

Viruses hijack deep-sea bacteria at hydrothermal vents

More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war.

How productive are the ore factories in the deep sea?

About ten years after the first moon landing, scientists on earth made a discovery that proved that our home planet still holds a lot of surprises in store for us. Looking through the portholes of the submersible ALVIN near ...

New critter discovered on whale carcass

A new species of bug, similar in appearance to the common woodlouse, has been found plastered all over a whale carcass on the floor of the deep Southern Ocean.

New study outlines 'water world' theory of life's origins

(Phys.org) —Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime ...

Study tests theory that life originated at deep sea vents

One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is still intense debate about exactly how life ...
