How repeatable is evolutionary history?
Writing about the weird soft-bodied fossils found in the Burgess Shale in the Canadian Rockies, paleontologist Stephen Jay Gould noted that of 25 initial body plans exhibited by the fossils, all but four ...
More infectious diseases emerging because of climate change
The appearance of infectious diseases in new places and new hosts, such as West Nile virus and Ebola, is a predictable result of climate change, says a noted zoologist affiliated with the Harold W. Manter ...
Light pollution shown to affect plant growth and food webs
Artificial night time light from sources such as street lamps affects the growth and flowering of plants and even the number of insects that depend on those plants for food, a study published today confirms.
A new kind of light bulb traps insects that carry vector-borne diseases
How many researchers does it take to change a light bulb? And how many lives could they save by changing it?
Early stone tool making more sophisticated than originally thought
(Phys.org) —Researchers at the University of Liverpool have found that long and slender stone tools were made by human ancestors at least a million years ago – nearly twice as long ago as generally thought.
Plants convert energy at lightning speed
A new way of measuring how much light a plant can tolerate could be useful in growing crops resilient to a changing climate, according to scientists from Queen Mary University of London.
For spider monkeys, social grooming comes with a cost
Social grooming, or helping others to stay clean and free of lice and other ecto-parasites, has long been associated with hygiene and good health in wild primates. In the process of picking out ecto-parasites, ...
Researches find poop-throwing by chimps is a sign of intelligence
Fast-mutating DNA sequences shape early development
What does it mean to be human? According to scientists the key lies, ultimately, in the billions of lines of genetic code that comprise the human genome. The problem, however, has been deciphering that code. ...
New study shows use of tools supports learning in nonhuman species
(Phys.org) —Leave young children alone with a soccer ball or a plastic shovel, and they quickly begin to put the object to use, especially if they've observed adults kicking the ball or using the shovel ...
How plants may be evolving to the lack of bees
Plants which used to have two types of male reproductive organs – to increase their chances for fertilisation – are reverting back to one type. And in some cases, they are becoming self-fertilising.
What evolved first—a dexterous hand or an agile foot?
Resolving a long-standing mystery in human evolution, new research from the RIKEN Brain Science Institute indicates that early hominids developed finger dexterity and tool use ability before the development ...
Robot researcher combines nature to nurture 'superhuman' navigation
Computer modelling of the human eye, the brain of a rat and a robot could revolutionise advances in neuroscience and new technology, says a QUT leading robotics researcher.
Alaska tundra shows surprising resilience after unprecedented fire
Despite the size and severity of the massive 2007 Anaktuvuk River fire on Alaska's North Slope, much of the arctic vegetation has recovered and the tundra is likely to return to its pre-fire condition according ...
