| Archaeologist explains innovation of 'fluting' ancient stone weaponry Posted: 04 Apr 2017 01:00 PM PDT Approximately 13,500 years after nomadic Clovis hunters crossed the frozen land bridge from Asia to North America, researchers are still asking questions and putting together clues as to how they not only survived in a new landscape with unique new challenges but adapted with stone tools and weapons to thrive for thousands of years. Kent State University's Metin Eren, Ph.D., and his colleagues are not only asking these questions but testing their unique new theories.       |
| Mini brains from the petri dish Posted: 04 Apr 2017 09:44 AM PDT A new method could push research into developmental brain disorders an important step forward. This is shown by a recent study in which the researchers investigated the development of a rare congenital brain defect. To do so, they converted skin cells from patients into so called induced pluripotent stem cells. From these 'jack-of-all-trades' cells, they generated brain organoids – small three-dimensional tissues which resemble the structure and organization of the developing human brain.  |
| Future carbon dioxide, climate warming potentially unprecedented in 420 million years Posted: 04 Apr 2017 09:44 AM PDT Over the next 100 to 200 years, carbon dioxide concentrations in the Earth's atmosphere will head towards values not seen since the Triassic period, 200 million years ago. Furthermore, by the 23rd century, the climate could reach a warmth not seen in 420 million years, say researchers.  |
| Oldest remains of insects from bed bug genus found in Oregon Posted: 04 Apr 2017 07:48 AM PDT A cave in Oregon that is the site of some the oldest preserved evidence of human activity in North America was also once home to not-too-distant cousins of the common bed bug. Archaeologists describe remains found in caves near Paisley, Ore., that represent the oldest specimens of insects from the genus Cimex ever found, ranging between 5,100 and 11,000 years old.  |
| DNA double helix structures crystals Posted: 04 Apr 2017 07:47 AM PDT Engineers have now succeeded in producing complex crystal lattices, so-called clathrates, from nanoparticles using DNA strands. The programmed synthesis of clathrates represents a template for the precision modelling of novel nanomaterials.  |
| Touch-sensitive, elastic fibers offer new interface for electronics Posted: 04 Apr 2017 07:47 AM PDT Researchers have created elastic, touch-sensitive fibers that can interface with electronic devices.  |
| Materials may lead to self-healing smartphones Posted: 04 Apr 2017 05:44 AM PDT Taking a cue from the Marvel Universe, researchers report that they have developed a self-healing polymeric material with an eye toward electronics and soft robotics that can repair themselves. The material is stretchable and transparent, conducts ions to generate current and could one day help your broken smartphone go back together again.  |
| The value of second opinions demonstrated in study Posted: 04 Apr 2017 05:44 AM PDT Many patients seek a second opinion or diagnosis confirmation before treatment for a complex condition. In a new study, researchers report that as many as 88 percent of those patients go home with a new or refined diagnosis -- changing their care plan and potentially their lives. Conversely, only 12 percent receive confirmation that the original diagnosis was complete and correct.  |
| New invention uses bacteria to purify water Posted: 04 Apr 2017 05:44 AM PDT A new system that uses bacteria to turn non-potable water into drinking water will be tested next week in West Vancouver prior to being installed in remote communities in Canada and beyond.  |
| Steppe migrant thugs pacified by Stone Age farming women Posted: 04 Apr 2017 05:44 AM PDT When present day European genetics was formed during the beginning of the Bronze Age 5,000 years ago it was a result of migrating Yamnaya pastoralists from the Caspian steppe encountering Stone Age farmers in northern and eastern Europe. A grand synthesis article argues that young Yamnaya warriors belonging to raiding parties married local Stone Age women, settling and adopting a more agrarian lifestyle. During this process, where the Corded Ware Culture was formed, a new Proto-Germanic dialect appeared.  |
| Ridding the oceans of plastics by turning the waste into valuable fuel Posted: 03 Apr 2017 05:30 AM PDT Billions of pounds of plastic waste are littering the world's oceans. Now, an organic chemist and a sailboat captain report that they are developing a process to reuse certain plastics, transforming them from worthless trash into a valuable diesel fuel with a small mobile reactor that could operate on land or at sea.  |
| A 'bionic leaf' could help feed the world Posted: 03 Apr 2017 05:30 AM PDT In the second half of the 20th century, an agricultural boom called the 'green revolution' was largely credited with averting a global food crisis. Now, the problem of feeding the world's growing population looms again. To help address the challenge, researchers have presented a 'bionic' leaf that uses bacteria, sunlight, water and air to make fertilizer in the very soil where crops are grown.  |
| Tests can help quantify automatic empathy and moral intuitions Posted: 30 Mar 2017 06:28 AM PDT When people scan the latest political headlines or watch a video from a war-ravaged land, they tend to feel snap ethical or moral responses first and reason through them later. Now a team of psychologists have developed news tests and mathematical models that help to capture and quantify those snap moral and empathetic judgments.  |
| Emissions from the edge of the forest Posted: 30 Mar 2017 06:27 AM PDT Half of the carbon stored in all of Earth's vegetation is contained in tropical forests. Deforestation has a correspondingly fatal effect. Scientists estimate that this releases 1,000 million tonnes of carbon every year, which, in the form of greenhouse gasses, drives up global temperatures. A team of scientists has discovered that fragmentation of formerly contiguous areas of forest leads to carbon emissions rising by another third.  |
