Tags on fish may act as 'dinner bell' for seals
Sound-emitting tags fitted to fish to track their survival may, paradoxically, be alerting predator seals to their whereabouts, said scientists Wednesday who warned of a "dinner bell" effect.
Ancient genetic program employed in more than just fins and limbs
Hox genes are master body-building genes that specify where an animal's head, tail and everything in between should go. There's even a special Hox gene program that directs the development of limbs and fins, ...
Warmer temperatures limit impact of parasites, boost pest populations
Climate change is expected to disrupt ecosystems by changing the life cycles of insects and other organisms in unpredictable ways - and scientists are getting a preview of these changes in cities. Research from North Carolina ...
Calcium loss turning lakes to 'jelly'
New research on a number of Canadian lakes show that historical acid deposits as a result of industry have greatly reduced calcium levels in the water - dramatically impacting populations of calcium-rich ...
Clean energy 'bio batteries' a step closer
Researchers from the University of East Anglia (UEA) are a step closer to enhancing the generation of clean energy from bacteria.
Cells' natural response to chronic protein misfolding may do more harm than good
"Protein misfolding" diseases such as cystic fibrosis and Alzheimer's may be seriously exacerbated by the body's own response against that misfolding, according to a new study led by scientists at The Scripps ...
Scientists get to the heart of fool's gold as a solar material
As the installation of photovoltaic solar cells continues to accelerate, scientists are looking for inexpensive materials beyond the traditional silicon that can efficiently convert sunlight into electricity.
Ancient New Zealand 'Dawn Whale' identified
University of Otago palaeontologists are rewriting the history of New Zealand's ancient whales by describing a previously unknown genus of fossil baleen whales and two species within it.
Paramecia need Newton for navigation
While single-celled paramecia have the ability to respond to certain external stimuli, they appear not to use that sensory system for simple navigation, new research finds. The work suggests that the ability ...

House fly sex may reveal one key to controlling them
The quest of University of Houston professor Richard Meisel to understand how and why males and females differ may one day lead to a more effective means of pest control - namely, the pesky house fly.
Small volcanic eruptions could be slowing global warming
Small volcanic eruptions might eject more of an atmosphere-cooling gas into Earth's upper atmosphere than previously thought, potentially contributing to the recent slowdown in global warming, according to ...
