Primitive air-breathing fish, whose direct ancestors first appeared around 400 million years ago, show mechanisms controlling the heart which were previously considered to be found only in mammals -- according to a new study.
Mammals show an increase in heart...
The tiny fossil of a prehistoric baby bird is helping scientists understand how early avians came into the world in the Age of Dinosaurs.
The fossil, which dates back to the Mesozoic Era (250-65 million years ago), is a chick...
Scientists report in the journal eNeuro that they've built an artificially intelligent ocean predator that behaves a lot like the original flesh-and-blood organism on which it was modeled. The virtual creature, "Cyberslug," reacts to food and responds to members of its...
University of Adelaide researchers have discovered how grapes "breathe," and report that shortage of oxygen leads to cell death in the grape.
The discovery raises many questions about the potentially significant impacts on grape and wine quality and flavour and...
For the past 40 years, the total number of Adélie Penguins, one of the most common on the Antarctic Peninsula, has been steadily declining -- or so biologists have thought. A new study led by researchers from the Woods...
Take a good look at this photo: It shows you 1.6 billion years old fossilized oxygen bubbles, created by tiny microbes in what was once a shallow sea somewhere on young Earth.
The bubbles were photographed and analyzed by researchers...
For seven years as a graduate student at Montana State University, Rebecca Hochstein hiked into the backcountry of Yellowstone National Park.
Careful to avoid the bears whose tracks she saw on the trail, she collected samples from a 176-degree hot...
Everyone loves a nice plate of pasta. After all, starch is the ultimate energy food. Now, we have proof that carbo-loading has been a thing for at least 280 million years.
A team of Chinese and German scientists has discovered...
Super-resolution microscopy is a technique that can "see" beyond the diffraction of light, providing unprecedented views of cells and their interior structures and organelles. The technique has garnered increasing interest recently, especially since its developers won the Nobel Prize...
An international team of researchers has produced one of the most comprehensive evolutionary pictures to date by looking at one of the world's most iconic animal families -- namely elephants, and their relatives mammoths and mastodons-spanning millions of years.
The...
Moth scales, preserved in the mud of a coniferous forest lake, have been used to identify outbreaks of these insects over the past 10,000 years. This groundbreaking new technique, reported in the open-access journal Frontiers in Ecology and Evolution, can...
