Cat shelter findings: Less stress with box access
Molecular 'hats' allow in vivo activation of disguised signaling peptides
When someone you know is wearing an unfamiliar hat, you might not recognize them. Georgia Institute of Technology researchers are using just such a disguise to sneak biomaterials containing peptide signaling ...
Oxygen levels were only 0.1 percent of today's levels for roughly billion years before rise of animals
(Phys.org) —Geologists are letting the air out of a nagging mystery about the development of animal life on Earth.
Copying behavior in social groups may be governed by optimal control theory
Nature has provided herding animals and flocking birds with abilities to react to predator attacks and to sense risky features in their environment— like trees or cliffs—that might impede their defense. ...
Evolutionary history is a predictor of diversity of parasites in a species
The evolutionary history, body size and geographic range of an animal species are predictors for the diversity of parasites—or disease—that species carries, according to University of Georgia researchers.
Decreasing biodiversity affects productivity of remaining plants
When plant biodiversity declines, the remaining plants face diminishing productivity, say scientists in study published April 20 in the journal Proceedings of the National Academy of Sciences.
Study shows urban coyotes with mange more likely to make use of anthropogenic resources
Key to survival for endangered smalltooth sawfish
What may be the last habitat of one of the world's most bizarre fish has been highlighted by a researcher at the University of St Andrews.
Researchers create tool to predict avian flu outbreaks
A simple and effective portable tool to predict avian flu outbreaks on farms has been created by University of Guelph researchers.
With geomagnetic compass hooked to the brain, blind rats act like they can see
By attaching a microstimulator and geomagnetic compass to the brains of blind rats, researchers reporting in the Cell Press journal Current Biology on April 2 found that the animals can spontaneously learn ...
Tiny wasps provide vital clue to avoiding extinction
The mating behaviour of tiny wasps could provide vital clues to how animals can protect themselves from extinction.
An elephant never forgets the way to the watering hole
A study published in Proceedings of the Royal Society B tracked the movement of elephants across the African savannah. The elephants chose the shortest distances towards watering holes, pin-pointing the lo ...
Antibiotic effectiveness imperiled as use in livestock expected to increase
Antibiotic consumption in livestock worldwide could rise by 67 percent between 2010 and 2030, and possibly endanger the effectiveness of antimicrobials in humans, according to researchers from Princeton University, ...
Biologist finds animal groups share dominance dynamics
The cardinal rules of pecking orders extend well beyond birds and beaks, according to a new study led by a UNL biologist.
