Ancient Maya built sophisticated water filters

Posted: 22 Oct 2020 12:34 PM PDT

Ancient Maya in the once-bustling city of Tikal built sophisticated water filters using natural materials they imported from miles away, according to the University of Cincinnati. UC researchers discovered evidence of a filter system at the Corriental reservoir, an important source of drinking water for the ancient Maya in what is now northern Guatemala. UC […]
‘Grassland 2.0’ seeks to transform Upper Midwest agriculture through perennial grasslands

Posted: 22 Oct 2020 12:25 PM PDT

Bert Paris loves dairy farming. After more than 30 years, he’s beginning to transition the farm he operates near Belleville, Wisconsin, to his daughter, Meagan Farrell, who is excited about moving her family home to run it. Despite years of terrible headlines about the dairy industry, farmers like Paris and Farrell are bullish on dairy […]
Do the twist: Making two-dimensional quantum materials using curved surfaces

Posted: 22 Oct 2020 12:24 PM PDT

Scientists at the University of Wisconsin–Madison have discovered a way to control the growth of twisting, microscopic spirals of materials just one atom thick. The continuously twisting stacks of two-dimensional materials built by a team led by UW–Madison chemistry Professor Song Jin create new properties that scientists can exploit to study quantum physics on the […]
Innovation spins spider web architecture into 3D imaging technology

Posted: 22 Oct 2020 12:23 PM PDT

Purdue University innovators are taking cues from nature to develop 3D photodetectors for biomedical imaging. The Purdue researchers used some architectural features from spider webs to develop the technology. Spider webs typically provide excellent mechanical adaptability and damage-tolerance against various mechanical loads such as storms. “We employed the unique fractal design of a spider web for […]
This white paint could reduce the need for air conditioning by keeping surfaces cooler than surroundings

Posted: 22 Oct 2020 12:22 PM PDT

What if paint could cool off a building enough to not need air conditioning? Purdue University engineers have created white paint that can keep surfaces up to 18 degrees Fahrenheit cooler than their ambient surroundings – almost like a refrigerator does, but without consuming energy. According to the researchers, the paint would replace the need […]
Materials scientists discover design secrets of nearly indestructible insect

Posted: 22 Oct 2020 12:21 PM PDT

With one of the more awe-inspiring names in the animal kingdom, the diabolical ironclad beetle is one formidable insect. Birds, lizards and rodents frequently try to make a meal of it but seldom succeed. Run over it with a car, and the critter lives on. The beetle’s survival depends on two key factors: its ability […]
Scientists identify compound that stimulates muscle cells in mice

Posted: 22 Oct 2020 12:19 PM PDT

UCLA researchers have identified a compound that can reproduce the effect of exercise in muscle cells in mice. The findings are published in the journal Cell Reports Medicine. Normally, muscles get stronger as they are used, thanks to a series of chemical signals inside muscle cells. The newly identified compound activates those signals, which suggests that compounds […]
