Small, origami-inspired pop-up robots function autonomously
Inspired by the traditional Japanese art form of origami or 'folding paper,' researchers have developed a way to coax flat sheets of composite materials to self-fold into complex robots that crawl and turn.

UTSA researcher awarded NSF grant to create computer models for food insecurity project
Eric Jing Du, assistant professor of Construction Science in The University of Texas at San Antonio College of Architecture, has been awarded major funding from the National Science Foundation Interdisciplinary Behavioral and Social Science Research Program to complete a four-year research project about food security issues in West Africa using real-time simulation computer models. Du will apply models to predict human behavior in different scenarios relating to the food security issue.

Mercury in the global ocean
Mercury is a naturally occurring element as well as a by-product of such distinctly human enterprises as burning coal and making cement. Estimates of 'bioavailable' mercury -- forms of the element that can be taken up by animals and humans -- play an important role in everything from drafting an international treaty designed to protect humans and the environment from mercury emissions, to establishing public policies behind warnings about seafood consumption.

Researchers boost insect aggression by altering brain metabolism
Scientists report they can crank up insect aggression simply by interfering with a basic metabolic pathway in the insect brain. Their study, of fruit flies and honey bees, shows a direct, causal link between brain metabolism -- how the brain generates the energy it needs to function -- and aggression.

An embryonic cell's fate is sealed by the speed of a signal
Early in development, chemical signals tell cells whether to turn into muscle, bone, brain or other tissue. By tracking cells' responses to signals, researchers found the speed at which the signal arrives has an unexpected influence on that decision.

Newly discovered juvenile whale shark aggregation in Red Sea
Whale sharks (Rhincodon typus) -- which grow more than 30 feet long -- are the largest fish in the world's ocean, but little is known about their movements on a daily basis or over years. A newly discovered juvenile whale shark aggregation off Saudi Arabia is giving researchers a rare glimpse into the lives of these gentle giants.

WSU researchers see violent era in ancient Southwest
In numbers terms, the 20th Century was the most violent in history, with civil war, purges and two World Wars killing as many as 200 million people. But on a per-capita basis, Tim Kohler has documented a particularly bloody period more than eight centuries ago. Between 1140 and 1180, in the central Mesa Verde of southwest Colorado, four relatively peaceful centuries of pueblo living devolved into several decades of violence.

Study traces evolutionary origins of migration in New World birds
A team of scientists from the University of Chicago have developed a new method to reveal the ancestral ranges of New World birds, and discovered that bird migration in the Americas evolved in species that resided in North America. Their work also offers evidence that many tropical bird species descended from migratory ancestors that lost migration. The study was published Aug. 4 in the Proceedings of the National Academy of Sciences.

Sulfur signals in Antarctic snow reveal clues to climate, past and future
Atmospheric chemists were surprised to see anomalous ratios of sulfur isotopes in sulfate deposited during worldwide wildfires following the super ENSO of '97 to '98, an event that marked the beginning of an apparent hiatus in global warming. Their analysis of the photochemistry that left this trace also revealed the importance of an overlooked reaction that could alter ideas about the oxygen state of Earth's early atmosphere.

Atlantic origin of recent Pacific trade wind, sea level and temperature trends
Climate models predict that the equatorial Pacific trades should weaken with increasing greenhouse gases; yet since the 1990s, satellites and climate stations show they have strengthened, resulting in accelerated sea level rise in the western Pacific and in both Pacific and global climate change. According to work published by an Australian-US team of climate researchers in this week's Nature Climate Change, these Pacific trends stem from a rapid warming of the Atlantic Ocean.

Kangaroos win when Aborigines hunt with fire
Australia's Aboriginal Martu people hunt kangaroos and set small grass fires to catch lizards, as they have for at least 2,000 years. A University of Utah researcher found such man-made disruption boosts kangaroo populations -- showing how co-evolution helped marsupials and made Aborigines into unintentional conservationists.

A hellacious two weeks on Jupiter's moon Io
During a year-long series of observations of Jupiter's volcanically active moon, Io, UC Berkeley astronomers Imke de Pater and graduate student Katherine de Kleer observed within a two week period in August 2013 three of the largest outbursts ever seen on the moon, all probably involving lava erupting through fissures in curtains of fire. The observations by the Keck and Gemini telescopes in Hawaii suggest that outbursts are more common than previously thought.
