New model to track animal paths from solar geolocators

The ability to track animal movements across long distances has revolutionized our understanding of animal ecology and has been helpful to conservation. Until recently, our ability to record this information was limited to ...

Improving toxicity prediction with cutting-edge data modelling

Today's state-of-the-art methods for the replacement of in vivo testing for toxicity in humans are on the cutting edge of science. However, they have not yet allowed us to completely eliminate the need for animal testing. ...

The delicate balance of outrunning a predator

Imagine you are crossing a stream over a fallen log. How fast would you walk across? Probably fairly slowly, balancing carefully as you go. Now imagine you are being chased by a bear. How fast should you cross the stream?

'Chromosome shattering' seen in plants, cancer

Plants can undergo the same extreme 'chromosome shattering' seen in some human cancers and developmental syndromes, UC Davis researchers have found. Chromosome shattering, or 'chromothripsis,' has until now only been seen ...

New model sheds light on 'flocking' behaviour

Understanding how turbulence can alter the shape and course of a flock of birds, a swarm of insects or even an algal bloom could help us to better predict their impact on the environment.

Infectious ants become antisocial

Looking after yourself, and trying not to infect others, is a good strategy to prevent disease from spreading - not only if you are a considerate co-worker, but also if you are an ant, meerkat or other social animal, as revealed ...

New thesis maps the origin of colour vision

Roughly 500 million years ago, the genome of vertebrate animals' early ancestors doubled in size, not just once but twice. This meant that suddenly there were several gene copies which were free to develop new functions. ...

Brain tumor cells decimated by mitochondrial 'smart bomb'

An experimental drug that attacks brain tumor tissue by crippling the cells' energy source called the mitochondria has passed early tests in animal models and human tissue cultures, say Houston Methodist scientists.
