Researchers detail what makes costly ruminant bacteria so infectious

An Iowa State University research team has identified the specific mutations that have led to the virulence of a major bacterial threat to ruminant animals such as cattle and sheep.

The discovery could pave the way for new treatment options and possibly even a vaccine to help sheep and cattle producers fend off the bacteria, said...

Shedding light on the origin of the baleen whale

Monash University scientists have played a key role in discovering the origin of filter feeding in baleen whales -- the largest animal known to have ever existed.

The discovery is detailed in a paper co-written with international researchers and palaeontologists from Museum Victoria. 'Alfred' the 25- million-year-old fossilised whale skull was unveiled at the Museum today.

Songbirds sound the alarm about traffic noise

A new study led by Pacific University biologist Chris Templeton demonstrates that the alarm calls of songbirds are dramatically impaired by road traffic noise. Research by Templeton and colleagues has shown that signals critical for the survival of animals are compromised when birds live near even moderately busy roads.

The study appears in the Nov. 21...

Using sound to stop destructive beetles in their tracks

What would the paradise of Hawaii be without swaying coconut palms, with succulent fruit that is almost synonymous with the tropical island? Unfortunately, that may be the future of the island unless scientists find some way to stop the destructive Coconut Rhinoceros Beetle which feeds on the coconut palms, stripping them of their leaves and...

Study explains evolution phenomenon that puzzled Darwin

Why do some animals have extravagant, showy ornaments -- think elk and deer antlers, peacock feathers and horns on dung beetles -- that can be a liability to survival? Charles Darwin couldn't figure it out, but now a Northwestern University research team has a possible explanation for this puzzling phenomenon of evolution.

The researchers developed a...

Learning makes animals intelligent

The fact that animals can use tools, have self-control and certain expectations of life can be explained with the help of a new learning model for animal behaviour. Researchers at Stockholm University and Brooklyn College have combined knowledge from the fields of artificial intelligence, ethology and the psychology of learning to solve several problems concerning...
