Construction waste is a growing problem in the United States. Waste consists of unwanted materials left over during new construction or renovations from both residential and commercial buildings. The waste consists of materials such as bricks, concrete, wood, asphalt shingles, and gypsum drywall. Some construction waste can be recycled and reused, but much of it ends up in landfills. This is especially true for drywall waste, which makes up nearly 10 percent of unrecycled construction waste.
In an effort to solve this problem, two Washington State University faculty members began developing masonry blocks using leftover drywall waste. The blocks are made from a high percentage … » More …
Secret weapons come in surprising shapes and sizes. For the National Park Service, it’s Washington State University’s Public Opinion Laboratory where, by simply asking questions, the agency wins battles over landfills, pipelines, diversity issues, and more.
Guided by director Lena Le, the laboratory employs more than 100 survey takers who make up the heart of the Social and Economic Sciences Research Center (SESRC). By phone, mail, and internet, the workers patiently collect data that adds up to very big impacts for a range of universities, businesses, and government agencies, including the National Park Service (NPS). Over the years, they’ve demonstrated that a well-designed survey can … » More …
For decades, doctors have trusted antibiotic medicines to fight Infectious bacteria, saving lives and restoring health. Lately, though, the drugs often fail. To blame are newly emerging antibiotic-resistant bacteria.
Drug-resistant bacterial infections cause nearly 23,000 deaths annually in the United States. Globally the annual death toll could be as high as 700,000.
WSU is part of global effort
Stopping antimicrobial resistance (AMR) requires a global effort. Washington State University is helping to lead the charge.
In the Paul G. Allen School for Global Animal Health, where experts study the emergence and spread of disease, researchers are examining the role … » More …
A complete picture of U.S. history requires the information held in tribal archives, libraries, and museums (TALMs). While many major libraries and museums now digitize their collections for access and use, many TALMs lack the resources to do so. In addition, traditional content management systems are organized under Western standards, not allowing for local narrations and other cultural practices and protocols important to archiving Native heritage.
Digitally preserving and sharing stories, artifacts, and images from diverse cultures is important in a technologically advancing world. WSU researcher Kim Christen is ensuring that digital history includes Native American voices stored and … » More …
New technology safeguards radioactive weapons and waste
Safe storage of nuclear weapons and waste is critical for national security and environmental health. Specialized seals are used to prevent tampering.
WSU researcher Hergen Eilers has developed a seal technology that adds a layer of security beyond what’s found in existing seals. His technology also allows for simple visual inspection to verify that a storage site is secure.
How the seal works
Dr. Eilers’ seals are composed of nano-particles embedded in a polymer. He uses a wavefront-modulated laser, which can control scattered light. When the laser interacts with the seal, the light is scattered by the particles. … » More …
Cross-laminated timber could invigorate the regional economy
Buildings stand among the nation’s leading producers of greenhouse gases. To blame is the energy used to operate them and the carbon-heavy materials required to construct them. With populations increasingly shifting toward urban centers, construction will only continue. Reducing emissions created by urban growth will require rethinking our built environment.
Much of that rethinking is happening at WSU, where architecture and engineering scholars are designing future skylines made of wood. Not often used in today’s urban infrastructures, wood is a renewable resource. It can be sustainably forested and manufactured into panels that have high-performance properties comparable to those of … » More …
Despite comparable levels of commitment, women don’t advance at the same rate as men
In the past 40 years, women have assumed a larger role in the U.S. workforce. While roughly two out of five women worked for pay in the early 1970s, almost three out of five do so today. But Julie Kmec, a Washington State University sociologist, has repeatedly seen how their roles, wages and mobility continue to differ dramatically from those of their male peers.
In a study of some 800 law firms, she found that a woman’s chance of promotion decreases as she advances. Nearly 40 percent of entry-level … » More …
Researchers seek ways to trap toxins and improve water quality
Paved surfaces cover tens of thousands of square miles in the United States. Almost all are impervious, collecting pesticides, fertilizers, oil, metals and other pollutants. The resulting runoff is one of the biggest threats to water quality.
On the west side of Washington State, abundant rain and a surging urban population create an ideal observatory for the problem. Working south of Seattle at Washington State University’s Research and Extension Center in Puyallup, researchers at the Washington Stormwater Center are working to address water-quality issues and develop effective, evidence-based management practices and principles.
Database houses genomic, genetic, and breeding information to help tree fruit growers
Washington, of course, is famous for its apples. Together with citrus, apples and related tree fruits comprise a $12.7 billion industry in the U.S. Staying ahead of diseases and pests, not to mention the search for the perfect combination of productivity and flavor, makes constant improvement a necessity.
WSU researcher Doreen Main, along with a team of fellow horticulture scientists, has created an online database to help growers around the world address these challenges.
