Dogs And Cats Can Live In Perfect Harmony In The Home, If Introduced The Right Way

ScienceDaily (2008-09-09) -- Thinking about adopting a perky little puppy as a friend for your fluffy cat, but worried that they'll fight -- well, like cats and dogs? Think again. New research has found a new recipe for success.

Even healthy cats act sick when their routine is disrupted

ScienceDaily (2011-01-04) -- A cat regularly vomiting hairballs or refusing to eat probably isn't being finicky or otherwise "cat-like," despite what conventional wisdom might say. There is a good chance that the cat is acting sick because of the stress caused by changes in its environment, new research suggests. Healthy cats were just as likely as chronically ill cats to refuse food, vomit frequently and leave waste outside their litter box in response to changes in their routine.

System for detecting noise pollution in the sea and its impact on cetaceans

ScienceDaily (2010-12-31) -- Researchers have developed the first system equipped with hydrophones able to record sounds on the seafloor in real time over the Internet. The system detects the presence of cetaceans and makes it possible to analyze how noise caused by human activity can affect the natural habitat of these animals and the natural balance of oceans. A new EU directive on the sea has ruled that all member states must comply with a set of indicators for measuring marine noise pollution before 2012.

Was Israel the birthplace of modern humans?

ScienceDaily (2010-12-31) -- Archaeologists have discovered evidence that places Homo sapiens in Israel as early as 400,000 years ago -- the earliest evidence for the existence of modern humans anywhere in the world.

Lower levels of education are associated with increased risks of heart failure

ScienceDaily (2010-12-31) -- Results from a large European study suggest that poorly educated people are more likely to be admitted to hospital with chronic heart failure than the better educated, even after differences in lifestyle have been taken into account.

What triggers mass extinctions? Study shows how invasive species stop new life

ScienceDaily (2010-12-31) -- An influx of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events, according to new research. The study of the collapse of Earth's marine life 378 to 375 million years ago suggests that the planet's current ecosystems, which are struggling with biodiversity loss, could meet a similar fate.
