One of the greatest scientific discoveries in history may be hidden beneath nearly 13,000 feet of Antarctic ice. Deep below the frozen surface lies Lake Vostok, a massive freshwater lake that has ...

Biologists are quietly rewriting what it means to be alive, and the human body has become one of their strangest frontiers. Inside our cells and microbiomes, researchers are uncovering entities that ...

Primitive life forms thrived on Mars around the same time prehistoric life was developing in Earth’s oceans — but the Red Planet’s denizens doomed themselves, a new study suggests. Mars’ ...

Imagine a life form that doesn't resemble any of the organisms found on the tree of life. One that has its own unique control system, and that a doctor would want to send into your body. It sounds ...

Tiny life forms tucked into debris from an asteroid hit could catapult to other planets—including Earth—and survive, a new Johns Hopkins University study finds. The work demonstrates that a certain ...

The extremely salty, very cold, and almost oxygen-free environment under the permafrost of Lost Hammer Spring in Canada's High Arctic is the one that most closely resembles certain areas on Mars. So, ...

Diverse microbial life existed on Earth at least 3.75 billion years ago, suggests a new study that challenges the conventional view of when life began. Diverse microbial life existed on Earth at least ...

Oxygen played a key role in the evolution of complex organisms, according to new research published in BMC Evolutionary Biology. The study shows that the complexity of life forms increased earlier ...

(CN) — In a study published Thursday that details ongoing international efforts to combat certain incurable diseases, scientists made an open call for research involving viral vaccines and artificial ...
