Matto Mildenberger, University of California Santa Barbara explains how perceived experiences with climate change in the United States can be linked to political shifts in Congress, culture and society. He will demonstrate how partisan opinions about the prevalence and dangers of climate change in each of the 50 states and 435 congressional districts in the United States can change policymaking by Congress.

Thomas Crowther identifies long-disappeared forests available for restoration across the world. He will describe how there is room for an additional 1.2 trillion new trees around the world that could absorb more carbon than human emissions each year. Crowther also describes data from thousands of soil samples collected by local scientists that reveal the world's Arctic and sub-Arctic regions store most of the world's carbon. But the warming of these ecosystems is causing the release of this soil carbon, a process that could accelerate climate change by 17%.
One of the most significant challenges of the 21st Century is how to sustainably feed a growing and more affluent global population with less water and fertilizers on shrinking acreage, despite stagnating yields, threats of pests and disease, and a changing climate.
Tuning the light intensity and reducing the concentration of atmospheric particulate matter (PM) in commercial buildings are both crucial to keep indoor people comfortable and healthy. While, the intelligent smart windows fabricated on the flexible transparent electrodes can change its transmittance in response to electrical or thermal stimulus to tune the light intensity of commercial buildings to maintain thermal comfort. Up to now, it is still a significant challenge to fabricate the large-scale flexible transparent smart window for high-efficiency PM2.5 capture.
In our daily lives, we can find many examples of manipulation of reflected waves such as mirrors to see our reflections or reflective surfaces for sound that improve auditorium acoustics. When a wave impinges on a reflective surface with a certain angle of incidence and the energy is sent back, the angle of reflection is equal to the angle of incidence. This classical reflection law is valid for any homogenous surface.
EVANSTON, Ill. --- Even Georgia O'Keeffe noticed the pin-sized blisters bubbling on the surface of her paintings. For decades, conservationists and scholars assumed these tiny protrusions were grains of sand, kicked up from the New Mexico desert where O'Keeffe lived and worked. But as the protrusions began to grow, spread and eventually flake off, people shifted from curious to concerned.
CHICAGO--On February 16, the Art Institute of Chicago announced the results of significant new research on five terracotta sculptures--so named Bankoni after a village in present-day Mali where they were found. The objects date from between the 12th and 15th centuries. This places them "among the oldest surviving sculptures from sub-Saharan Africa and among the oldest works of African art in the Art Institute's collection beyond Egypt," according to Constantine Petridis, Chair of the Arts of the Americas and Africa and Curator of African Art at the Art Institute of Chicago.
While the polyester leisure suit was a 1970s mistake, polyester and other synthetic fibers like nylon are still around and are a major contributor to the microplastics load in the environment, according to a Penn State materials scientist, who suggests switching to biosynthetic fibers to solve this problem.
"These materials, during production, processing and after use, break down into and release microfibers that can now be found in everything and everyone," said Melik Demirel, Lloyd and Dorothy Foehr Huck Endowed Chair in Biomimetic Materials.
The promises of quantum computing are abundant: for years we've heard how it will break cryptography, make drug discovery a cinch and speed up database search. Researchers around the world have successfully made quantum computers with dozens of quantum bits, but in order to deliver on the promises, they'll need many more.
Current lithium ion battery technology will probably not be able to handle the coming decades' huge demand for energy. It is estimated that by 2050, electricity will make up 50% of the world's energy mix. Today that rate is 18%. But installed capacity for renewable energy production is expected to increase fourfold. This will require batteries that are more efficient, cheaper and environmentally friendly.
