Suspended students more likely to get caught up in juvenile justice system, and vice versa
Students who are suspended from school even once are much more likely to have contact with the juvenile justice system, according to new research from Rice University's Houston Education Research Consortium (HERC), which also shows that students who come in contact with the juvenile justice system are more likely to face suspension.
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.
Nature's strongest glue now works in both wet and salty environments
Université de Montréal microbiologist Yves Brun made the discovery several years ago: an aquatic bacterium called Caulobacter crescentus produces an extremely powerful glue that adhere to its surrounding wet surfaces, such as pipes and fresh water.
Researchers create mirror-image peptides that can neutralize SARS-CoV-2
Researchers at the University of Toronto have created chemical compounds that can neutralize SARS-CoV-2 and several of its variants.
Promising new antimalarial compound discovered
A study out of the Michael G. DeGroote Institute for Infectious Disease Research at McMaster University has resulted in the discovery of a promising new antimalarial compound.
Looking up answers online can leave us overconfident about what we know
From the number of ounces in a cup to the first day of fall, online search engines such as Google put the answers to seemingly any question at our fingertips, making more knowledge accessible than ever before.
Scientists identify protein that stops cell cycle in response to stress
UT Southwestern researchers have identified a new mechanism by which stress causes cells to stop dividing.
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.
Taking the pulse of flies: Study reveals fly hearts respond to danger the same way human hearts do
The sound of an accelerating heartbeat can instantly send chills down your spine. You know that sound means trouble. We are so accustomed to the way our hearts seem to continuously mirror how we feel that we can easily imagine different hearts racing, aching or skipping a beat.
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...
