When does reputation lie?

Consider two stories: the first, about a boy who gets all the attention. He's the cool kid in class who comes from a well-known family. He seems to soar through life. When he errs, few seem to care. The more popular he is, the more beloved he becomes. The second: a girl who can't thrive. She tries and tries, to no avail. She's smart and kind, but she has few friends. The more she's shunned, the...

New tool untangles complex dynamics on hypergraphs

Networks are a powerful model for describing connected systems in biological, physical, social, and other environments. As useful as they are, though, conventional networks are static and are limited to describing links between pairs of objects; they can't capture more complicated connections, like those that connect many points at once or those that change over time.

Computational discovery of complex alloys could speed the way to green aviation

Computational materials science experts at the U.S. Department of Energy's Ames Laboratory and their collaborators have identified the source of and the way to tune the strength and ductility of a class of materials called high-entropy alloys. The discovery may help power-generation and aviation industry develop more efficient engines, reducing fuel consumption and carbon emissions.

Making Martian rocket biofuel on Mars

Researchers at the Georgia Institute of Technology have developed a concept that would make Martian rocket fuel, on Mars, that could be used to launch future astronauts back to Earth.

Want to visualize the realities of a warmer planet? Give this online tool a try

The Clark Fork River drains much of western Montana, bringing water from the Crown of the Continent to the Columbia River and the Pacific Ocean. My daily commute via bicycle crosses the Clark Fork most days and has allowed me to discern a rhythm and tempo in how the seasons come and go—a composition of daily weatherlike notes in a musical score that is the climate of Missoula, Montana.

The surprising origins of the Tarim Basin mummies

As part of the Silk Road and located at the geographical intersection of Eastern and Western cultures, the Xinjiang Uyghur Autonomous Region has long served as a major crossroads for trans-Eurasian exchanges of people, cultures, agriculture, and languages. Since the late 1990s, the discovery of hundreds of naturally mummified human remains dating to circa 2,000 BCE to 200 CE in the region's Tarim...

Powerful X-ray technique finds new degradation-inducing materials in British shipwreck

In 1545, King Henry VIII's favorite ship, the Mary Rose, capsized and sank in the Battle of the Solent defending England and Portsmouth from a French invasion fleet. The wreck remained on the seabed until 1982 when it was salvaged in a widely viewed televised event. Now, it is a time capsule for 16th century Tudor society, and conservators are working to preserve it for future generations. In...

Biodiversity collections address science workforce needs

The task of training an effective cadre of biodiversity scientists has grown more challenging in recent years, as foundational skills and knowledge in organismal biology have increasingly required complementary data skills and knowledge. Writing in BioScience, Dr. Anna K. Monfils, of Central Michigan University, and colleagues identify one way to address this training conundrum: biodiversity...
