Building knowledge for a healthier world

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 …

Addressing health disparities and preventing disease

American Indian, Alaska Native, Native Hawaiian, and Pacific Islander communities experience elevated rates of hypertension, cardiovascular disease, and stroke. These communities are historically underserved when it comes to health care. Little research has been conducted to better understand and address their health care needs.

Dr. Dedra Buchwald of the WSU Health Sciences Spokane campus hopes to equip these communities with powerful tools to improve blood pressure control, and ultimately cardiovascular disease and stroke. With a $10 million grant from the National Institute on Minority Health and Health Disparities, Dr. Buchwald will work with a Southwest tribe, an Alaska Native health … » More …

Advancing the health of communities worldwide

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 …

Preserving indigenous traditions in digital form

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 promise for solar energy

A breakthrough by WSU researcher Kelvin Lynn could help solar energy compete with fossil fuels for generating electricity.

Commercial success of solar technology has been constrained by the cells’ performance and cost. Key to addressing both concerns are the materials from which solar cells are made.

Seeking an alternative to silicon

Silicon solar cells represent 90 percent of the solar cell market. Because silicon is a costly material to use in manufacturing, it keeps the price of solar cells high. A low-cost alternative is cadmium telluride (CdTe), which outperforms silicon in real-world conditions, such as low light and hot, humid … » 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 …
