How single-celled organisms navigate to oxygen

A team of researchers has discovered that tiny clusters of single-celled organisms that inhabit the world's oceans and lakes, are capable of navigating their way to oxygen. Writing in e-Life scientists at the University ...

Ocean toxicity hampered the rapid evolution of complex life

By examining rocks at the bottom of ancient oceans, an international group of researchers have revealed that arsenic concentrations in the oceans have varied greatly over time. But also that in the very early oceans, arsenic ...

New protein discovered gives insights to iron's fate underground

(Phys.org) -- It's almost an evil twin story: a protein that steals electrons from iron in one microbe looks a lot like one that adds electrons in another microbe, according to scientists at Pacific Northwest National Laboratory ...

Protein reveals oxygen availability to plants

(PhysOrg.com) -- Plants need water to grow, but every hobby gardener knows that you shouldn’t carry this to excess either. During waterlogging or flooding, plants can’t take up enough oxygen that they urgently need ...
