New Futuristic Fabrics to Keep Cool

September 20, 2016September 27, 2016 Science Connectedclothing, engineering, plastics, Stanford, textiles

By Katherine Lindemann Inspired by lithium batteries and kitchen plastic wrap, engineers at Stanford University have developed a plastic material that helps the body radiate heat, lowering skin temperature and cooling the wearer. To be suitable for clothing, the material is flexible and—importantly—opaque. The teams are now working on a woven version of the textile. Po-Chun Hsu contributed to the research as a member of the Yi Cui research group. We asked him to tell us more. ResearchGate: Where did the idea for this material come from? Po-Chun Hsu: The…

By Rosalind Rude I have a friend who pilots his own aircraft. He’s been away from it for a while so now he is boning up, re-sharpening his skills to get back in the saddle, or back in the cockpit. As he recently explained to me, piloting an aircraft is nothing like driving a car or riding a bike. Yaw, Pitch, and Roll There are three axes in play during flight: The airplane turns left and right (yaw). The airplane’s nose goes up and down (pitch). The body of…

By Kate Stone Earthquakes, floods, tsunamis, and landslides, and other natural disasters can damage infrastructure, such as bridges. What can be done to aid the rapid evacuation of survivors and delivery of aid? Enter the Mobile Bridge® Version 4.0 (MB4.0), a new concept in temporary bridge construction. In the aftermath of a natural disaster, rapid repair of infrastructure is crucial. Expanding in just five minutes and capable of carrying automobiles, MB4.0 is being hailed as the world’s fastest, largest, strongest, and lightest expanding temporary bridge. It’s a new type of…

By Kate S. Scientists at Stanford University have just built a low-cost water splitter that uses a single catalyst to produce both hydrogen and oxygen gas. This is an invention that could pave the way for a boom in production of clean-burning cars. The scientists say that their device, which can run nonstop for an unprecedented period of time, could provide a renewable source of clean-burning hydrogen fuel for transportation and industry. The team used lithium-ion battery technology to create one low-cost catalyst that is capable of driving the entire…

By Kate S. Today, the University of Cincinnati announced that, together with industry partners, they’ve invented new ‘smart window’ shade technology that could improve upon existing windows and blinds. The researchers say that this patent-pending research will lead to low-cost window tinting that dynamically adapts for brightness, color, and opacity. The new tech is designed to provide privacy while allowing light in. A collaboration between the University of Cincinnati, Hewlett Packard, and EMD/Merck Research Labs has resulted in a patent-pending product that the team is calling ‘tunable’ window tinting. The…

By Kate S. How many passwords do you keep track of? How many have you forgotten? According to researchers from Binghamton University, remembering lots of complicated codes may one day be a thing of the past. The unique way your brain responds to certain words could be used to replace passwords. Studying Brain Biometrics The research team monitored the brain signals of 45 volunteers as they read a list of 75 acronyms, such as FBI and DVD. They recorded the brain’s reaction to each group of letters, focusing on the…

By Kate S. Science and art go together beautifully. It just got a lot easier and cheaper to add complex surface art to your 3D printing creations. Researchers at Columbia Engineering and Zhejiang University in China have developed a technique that enables more precise 3D printing than ever before. 3D Printing Meets Hydrographic Printing Engineers often find ways to make our lives healthier, safer, and easier to clean. Sometimes, they make things easier to view, or in this case, more visually appealing. The new technique is based on hydrographic printing,…

Better Understanding the Human Grip

The human hand is an evolutionary wonder: 26 percent of the bones in our bodies are in our hands. Now, scientists are coming to better understand the grip and special grasping ability of humans and other primates. In a new study, a research team found that even the oldest known human ancestors may have had precision gripping skills comparable to modern humans. This includes Australopithecus afarensis, a creature that predates the first known stone tools by about a million years. Manual dexterity is traditionally viewed as a key adaptation that…

In 1969, two psychologists at the University of Illinois proposed what they called the Pollyanna Hypothesis–the idea that there is a universal human tendency to use positive, happy words more frequently than negative ones. “Humans tend to look on (and talk about) the bright side of life,” they wrote. That speculation has provoked debate ever since. Now, scientists at the University of Vermont have gathered a data set of billions of words to support the 1960s theory. People Use More Happy Words Than Sad Words The researchers collected samples of ten…
