To relieve customers of backbreaking yard work, various manufacturers have rolled out their versions of the automatic, robotic lawnmower.
A team of researchers with members from France, Ivory Coast, Switzerland and the U.K. has found that some monkeys of one species are able to listen in and respond to communications made by monkeys of another species. In their paper published in Proceedings of the Royal Society B, the researchers describe a field study they conducted with two monkey species and what they learned from it.
Researchers from Georgetown University Medical Center and American University have shown that, like humans, mustached bats use the left and right sides of their brains to process different aspects of sounds. Aside from humans, no other animal that has been studied, not even monkeys or apes, has proved to use such hemispheric specialization for sound processing—meaning that the left brain is better at processing fast sounds, and the right processing slow ones.
Researchers today announced the discovery of a stunning new dinosaur fossil: a glider with wings similar to both birds and bats. It has been named Yi qi (meaning ‘strange wing’) and is a small feathered dinosaur from the Middle Jurassic age fossil beds of China that have yielded a host of important fossils in recent years. Yi qi, like so many other small dinosaurs, is preserved with a full coating of feathers and was a close relative of the lineage that ultimately gave rise to birds.
The demise of Neanderthals may have nothing to do with innovative hunting weapons carried by humans from west Asia, according to a new study. The researchers say their findings mean that we may need to rethink the reasons humans survived Neanderthals - and that we may not have behaved as differently as we thought. The researchers looked at innovative stone weapons used by humans about 42,000-34,000 years ago. Traditionally, anthropologists believed that innovation in weapons enabled humans to spread out of Africa to Europe. However, the new study suggests that the innovation was not a driving force for humans to migrate into Europe as previously thought - they were no better equipped than the Neanderthals.
CHICAGO, Northwestern University—Genetic testing of Iñupiat people currently living in Alaska's North Slope is helping Northwestern University scientists fill in the blanks on questions about the migration patterns and ancestral pool of the people who populated the North American Arctic over the last 5,000 years.
About five years after the footprint of the first Jamestown colony church was discovered, archaeologists and other specialists are busy partially reconstructing the structure. Believed to be the place where Pocahontas married the English tobacco planter John Rolfe, archaeologists hope that the reconstruction will provide the public with a real life, physical replica of the building that made history more than 400 years ago near the banks of the James River in southern Virginia.
Nine hundred kilometers off the east coast of Madagascar lies the tiny island paradise of Mauritius. The waters are pristine, the beaches bright white, and the average temperature hovers between 22°C and 28°C (72°F to 82°F) year-round. But conditions there may not have always been so idyllic. A new study suggests that about 4000 years ago, a prolonged drought on the island left many of the native species, such as dodo birds and giant tortoises, dead in a soup of poisonous algae and their own feces.
A citizen science project has found that penguins use their faeces to melt rocky breeding sites in order to lay their eggs.
Male species of a West African monkey communicate using at least these six main sounds: boom-boom, krak, krak-oo, hok, hok-oo and wak-oo.
Imagine having a different accent from someone else simply because your house was farther up the same hill. For at least one species of songbird, that appears to be the case. Researchers have found that the mating songs of male mountain chickadees (Poecile gambeli, shown) differ in their duration, loudness, and the frequency ranges of individual chirps, depending in part on the elevation of their habitat in the Sierra Nevada mountains of the western United States.
On their arduous flights North to their breeding grounds, birds migrating up the US East Coast will have one less peril to worry about - bright lights from state-owned and -managed buildings in New York.
Artificial lighting in harbours is attracting sea creatures that damage ships and boats, a study suggests.
An airborne survey of a presumably dry Antarctic valley revealed a stunning and unexpected interconnected subsurface briny aquifer deep beneath the frozen tundra, a finding that not only has implications for understanding extreme habitats for life on Earth, but the potential for life elsewhere in the solar system, particularly Mars.

Scientists have long pondered whether hot vents on the seabed could have been where life on Earth began.
Like cars, some microbes use oil as fuel. Such microorganisms are a big reason why BP's 2010 oil spill in the Gulf of Mexico was not far worse.
About 1% of all the tree species in the Amazon account for half of the carbon locked in the vast South American rainforest, a study has estimated.
