New instrument dates old skeleton; 'Little Foot' 3.67 million years old
A skeleton named Little Foot is among the oldest hominid skeletons ever dated at 3.67 million years old, according to an advanced dating method. Little Foot is a rare, nearly complete skeleton of Australopithecus first discovered 21 years ago in a cave at Sterkfontein, in central South Africa. Stone tools found at a different level of the Sterkfontein cave also were dated at 2.18 million years old, making them among the oldest known stone tools in South Africa.

Study: Ads in free mobile apps have hidden costs for both users and developers
Advertising may allow developers to make smartphone apps free, but it has hidden costs -- draining batteries, eating up network data, and using more memory.

Springing ahead of nature: Device increases walking efficiency
It's taken millions of years for humans to perfect the art of walking. But research results published today in the journal Nature show that humans can get better 'gas mileage' using an unpowered exoskeleton to modify the structure of their ankles. The device puts an extra spring in each human step, reducing metabolic energy consumption by 7 percent below walking in normal athletic shoes.

Discovering missing body parts of ancient fossils
Certain specimens of the fossil Dickinsonia are incomplete because ancient currents lifted them from the sea floor, a team of researchers led by paleontologists at the University of California, Riverside has found. Sand then got deposited beneath the lifted portion, the researchers report, strongly suggesting that Dickinsonia was mobile, easily separated from the sea floor and not attached to the substrate on which it lived.

Better method for forecasting hurricane season
A better method for predicting the number of hurricanes in an upcoming season has been developed by a team of University of Arizona atmospheric scientists. The UA team's new model improves the accuracy of seasonal hurricane forecasts for the North Atlantic and the Gulf of Mexico by 23 percent. The team's research paper was published online in the journal Weather and Forecasting on March 25.

Methane monitoring method reveals high levels in Pennsylvania stream
A new stream-based monitoring system recently discovered high levels of methane in a Pennsylvania stream near the site of a reported Marcellus shale gas well leak, according to researchers at Penn State and the US Geological Survey. The system could be a valuable screening tool to assess the environmental impact of extracting natural gas using fracking.

The nature of nurture is all about your mother, study says
When it comes to survival of the fittest, it's all about your mother -- at least in the squirrel world. New research from the University of Guelph shows that adaptive success in squirrels is often hidden in the genes of their mother. 'Some squirrels are genetically better at being mothers than others,' said Andrew McAdam, a professor in U of G's Department of Integrative Biology and co-author of the study published today in Proceedings of the Royal Society.

Isotope study shows which urban ants love junk food
Research finds that some -- but not all -- of the ant species on the streets of Manhattan have developed a taste for human food, offering insight into why certain ants are thriving in urban environments. The findings stem from a study that tested isotope levels in New York City ants to determine the makeup of their diet.

Massive study is first to explore historical ocean response to abrupt climate change
A new study reports that marine ecosystems can take thousands, rather than hundreds, of years to recover from climate-related upheavals. The study's authors -- including Peter Roopnarine, Ph.D., of the California Academy of Sciences -- analyzed thousands of invertebrate fossils to show that ecosystem recovery from climate change and seawater deoxygenation might take place on a millennial scale.

Clues to aging from long-lived lemurs
Researchers combed through more than 50 years of medical records on hundreds of lemurs at the Duke Lemur Center for clues to their longevity. They found that how long these primates live and how fast they age correlates with the amount of time they spend in a state of suspended animation known as torpor. The research may eventually help scientists identify 'anti-aging' genes in humans.

To help scientists make sense of 'brain big data,' researchers at Carnegie Mellon University have used data mining to create, a publicly available website that acts like Wikipedia, indexing physiological information about neurons. The site will help to accelerate the advance of neuroscience research by providing a centralized resource for collecting and comparing data on neuronal function.

Setting a dinner table for wildlife can affect their risk of disease
Supplemental feeding of wildlife can increase the spread of some infectious diseases and decrease the spread of others. A new study by University of Georgia ecologists finds that the outcome depends on the type of pathogen and the source of food. The findings, published in the journal Ecology Letters, have implications for human health and wildlife conservation, and contain practical suggestions for wildlife disease management and a roadmap for future study.

Glimpses of the future: Drought damage leads to widespread forest death
The 2000-2003 drought in the American southwest triggered a widespread die-off of forests around the region. A team of scientists developed a new modeling tool to explain how and where trembling aspen forests died as a result of this drought, based on damage to the individual trees' ability to transport water. Their results suggest that more widespread die-offs of aspen forests triggered by climate change are likely by the 2050s.
