Neanderthals and modern H. sapiens crossbred over 100,000 years ago

Madrid, Spain (SPX) Feb 18, 2016
A multidisciplinary team which included participants from the Spanish National Research Council (CSIC) has discovered that Homo neanderthalensis and Homo sapiens crossbred over 100,000 years ago. This puts back the previously first-known case of a hybrid produced by the two species by 50,000 years. This earlier genetic exchange, which may have taken place in the Near East, has not been detected

Breaking the strongest link triggered Big Baja Earthquake

Davis CA (SPX) Feb 18, 2016
A spate of major earthquakes on small faults could overturn traditional views about how earthquakes start, according to a study from researchers at the Centro de Investigacion Cientifica y de Educacion Superior in Ensenada, Mexico, and the University of California, Davis. The study, published in the journal Nature Geoscience, highlights the role of smaller faults in forecasting California's risk

500 million-year-old fossils show how extinct organisms attacked their prey

Columbia MO (SPX) Feb 18, 2016
The Cambrian Period, which occurred between 541 million and 485 million years ago, is an important point in evolutionary history where most of the major groups of animals first appear in the fossil record. Often called the "Cambrian explosion," fossils from this time provide glimpses into evolutionary history as the world's ecosystems were rapidly diversifying. Most fossils preserve the ph

How hunter-gatherers preserved their food sources

Santa Fe NM (SPX) Feb 18, 2016
A new study of humans on Sanak Island, Alaska and their historical relationships with local species suggests that despite being super-generalist predators, the food gathering behaviors of the local Aleut people were stabilizing for the ecosystem. The findings provide insights into how human roles and behavior impact complex ecological networks and offer new quantitative tools for studying

Renewable fuels from algae boosted by NREL refinery process

Golden CO (SPX) Feb 18, 2016
A new biorefinery process developed by scientists at the Energy Department's National Renewable Energy Laboratory (NREL) has proven to be significantly more effective at producing ethanol from algae than previous research. The process, dubbed Combined Algal Processing (CAP), is detailed in a new paper by NREL's Tao Dong, Eric Knoshaug, Ryan Davis, Lieve Laurens, Stefanie Van Wychen, Philip

Enabling human-robot rescue teams

Boston MA (SPX) Feb 18, 2016
Autonomous robots performing a joint task send each other continual updates: "I've passed through a door and am turning 90 degrees right." "After advancing 2 feet I've encountered a wall. I'm turning 90 degrees right." "After advancing 4 feet I've encountered a wall." And so on. Computers, of course, have no trouble filing this information away until they need it. But such a barrage of data woul

Soilless farming suggested as a solution to food shortage in Qatar

London, UK (SPX) Feb 18, 2016
Soilless farming could help developing countries with little arable land and harsh for agriculture climate, such as Qatar, to become self-sufficient in terms of their produce. Relying on advanced hydroponics and multi-story vertical growing, the proposed system uses nutrient-enriched water to produce approximately a hundred times more yield compared to when the crops are grown on a conventional

Transgenic sweet corn no more susceptible to Goss's wilt disease

Urbana IL (SPX) Feb 18, 2016
Transgenic crops expressing resistance to the herbicide glyphosate (GR) have been commercialized and planted widely across the U.S. for two decades. The majority of transgenic corn (Bt) also has been engineered to produce toxins effective against certain corn insect pests. In recent years, claims have been made that glyphosate and transgenic traits result in corn plants that are more susceptible

DNA evidence shows that salmon hatcheries cause substantial, rapid genetic changes

Corvallis OR (SPX) Feb 18, 2016
A new study on steelhead trout in Oregon offers genetic evidence that wild and hatchery fish are different at the DNA level, and that they can become different with surprising speed. The research, published in Nature Communications, found that after one generation of hatchery culture, the offspring of wild fish and first-generation hatchery fish differed in the activity of more than 700 genes.

Mapping the world for climate sensitivity

Bergen, Norway (SPX) Feb 19, 2016
By developing this method, the international team of researchers has been able to map which areas are most sensitive to climate variability across the world. "Based on the satellite data gathered, we can identify areas that, over the past 14 years, have shown high sensitivity to climate variability," says researcher Alistair Seddon at the Department of Biology at the University of Bergen (

How climate change will affect western groundwater

Tucson AZ (SPX) Feb 18, 2016
By 2050 climate change will increase the groundwater deficit even more for four economically important aquifers in the western U.S., reports a University of Arizona-led team of scientists. The new report is the first to integrate scientists' knowledge about groundwater in the U.S. West with scientific models that show how climate change will affect the region. "We wanted to know, 'What are

New technique for turning sunlight into hydrogen

Ulsan, South Korea (SPX) Feb 18, 2016
A team of Korean researchers, affiliated with UNIST has recently pioneered in developing a new type of multilayered (Au NPs/TiO2/Au) photoelectrode that boosts the ability of solar water-splitting to produce hydrogen. According to the research team, this special photoelectrode, inspired by the way plants convert sunlight into energy is capable of absorbing visible light from the sun, and then us

Oxygen-starved oceans held back life's recovery after the 'Great Dying'

Stanford CA (SPX) Feb 18, 2016
Stanford scientists have found that chronically low levels of oxygen throughout the oceans hampered the recovery of life after the Permian-Triassic extinction, the most catastrophic die-off in our planet's history. Also known as the "Great Dying," global ecosystems collapsed as some 90 percent of species perished in this extinction event 250 million years ago. The new findings, published t

El Nino begins decline after 'powerful' impact: UN

Geneva (AFP) Feb 18, 2016
The 2015-2016 El Nino weather phenomenon, one of the most powerful on record, has begun its decline but continues to have a strong influence on global climate patterns, the UN's weather agency said Thursday. The World Meteorological Organization (WMO) said El Nino, which occurs every two to seven years, has "passed its peak" but ocean temperature rises in recent months proved its considerab

Neanderthals mated with modern humans much earlier than previously thought

Cold Spring Harbor NY (SPX) Feb 18, 2016
Using several different methods of DNA analysis, an international research team has found what they consider to be strong evidence of an interbreeding event between Neanderthals and modern humans that occurred tens of thousands of years earlier than any other such event previously documented. This week in Nature the team publishes evidence of interbreeding that occurred an estimated 100,00
