New populations of endangered fresh water fish found
Murdoch University researchers have discovered new populations of an endangered fresh water fish, the Little Pygmy Perch, near Denmark in Western Australia's south.
Certain virus-derived genomic elements have now been shown to actively regulate important developmental processes
Like fossils buried beneath a modern landscape, the human genome is littered with sequences that originated from ancient viral DNA insertion events. Scientists have long assumed that these 'transposable elements' ...
By watching people walk, researchers decode the foot position's role in maintaining balance
Researchers at The Ohio State University have gained new insight into how the body moves when we're walking. They learned everything they needed to know by watching people walk naturally on a treadmill.
At dusk and dawn: Scientists pinpoint biological clock's synchronicity
Scientists have uncovered how pacemaker neurons are synchronized at dusk and dawn in order to maintain the proper functioning of their biological clocks. Their findings, which appear in the journal PLOS Biology, enhance our un ...
Fish colon offers insight into evolution
Skates have primitive colons. This may not sound like a big deal, but it is. The discovery could change scientific understanding of evolution, of how animals emerged from water to live on land.
Study shows manure from cows not given antibiotics still causes increase in resistant bacteria in soil
180 million years of parasitic infestation in crustaceans
When Darwin suggested the "survival of the fittest" concept, he did not necessarily mean "survival of the biggest."
Stem cell physical
Looking at stem cells through physicists' eyes is challenging some of our basic assumptions about the body's master cells.
Fossilised bird egg offers clues to Brazil's prehistoric past
Brazilian scientists have discovered a near-intact fossilised bird egg – the country's first – in Sao Paulo State.
Collapsible wings help birds cope with turbulence
Collapsible wings may be a bird's answer to turbulence according to an Oxford University study in which an eagle carried its own 'black box' flight recorder on its back.
Could sleeper sharks be preying on protected Steller sea lions?
Pacific sleeper sharks, a large, slow-moving species thought of as primarily a scavenger or predator of fish, may be preying on something a bit larger – protected Steller sea lions in the Gulf of Alaska.
Gene doubling shapes the world: Instant speciation, biodiversity, and the root of our existence
What do seedless watermelon, salmon, and strawberries all have in common? Unlike most eukaryotic multicellular organisms that have two sets of chromosomes and are diploid, these organisms are all polyploid, meaning they have ...
On invasive species, Darwin had it right all along, study shows
Dov Sax of Brown University and Jason Fridley of Syracuse University aren't proposing a novel idea to explain species invasiveness. In fact, Charles Darwin articulated it first. What's new about Sax and Fridley's ...
Are Montana's invasive fish in for a shock?
A new paper from the Wildlife Conservation Society, Montana State University, Montana Department of Fish, Wildlife and Parks, and the U.S. Geological Survey looks at the feasibility of electrofishing to selectively ...
