New study rebuts 75-year-old belief in reptile evolution

Challenging a 75-year-old notion about how and when reptiles evolved during the past 300 million-plus years involves a lot of camerawork, loads of CT scanning, and, most of all, thousands of miles of travel. Just check the ...

Ancient effect harnessed to produce electricity from waste heat

A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind ...

Mediterranean diet's cellular effects revealed

People who follow the Mediterranean diet—rich in fats from olive oil and nuts—tend to live longer, healthier lives than others who chow down primarily on fast food, meat and dairy. But it hasn't been clear on a cellular ...

Scientists probe underground depths of Earth's carbon cycle

Understanding how carbon dissolves in water at the molecular level under extreme conditions is critical to understanding the Earth's deep carbon cycle—a process that ultimately influences global climate change.

Explainer: What is the molecular clock?

In the 150 years since Charles Darwin recognised the kinship of all life, scientists have worked to fulfil his dream of a complete Tree of Life. Today, the methods used to trace the evolutionary branches back through time ...

Plant protein discovery could reduce need for fertilizer

Researchers have discovered how a protein in plant roots controls the uptake of minerals and water, a finding which could improve the tolerance of agricultural crops to climate change and reduce the need for chemical fertilizers.
