Some 800 million people — one in every ten of the world's citizens — do not have enough daily food to eat, according to the United Nations' latest global hunger report. The vast majority live in developing nations, and the situation is actually worsening in Africa and South America due to globally warming temperatures. It's a huge humanitarian challenge.
As concrete makes a comeback in urban architecture worldwide, an innovative building material being developed by Stevens Institute of Technology researchers could revolutionize infrastructure.
And the material may help mitigate soil and groundwater pollution, as well, because it's produced using high-volume construction and demolition waste and industrial solid waste, which typically goes into landfills.
HURRICANE SEASON & CLIMATE CHANGE FAQs
Climate change is in the news, and on the world's political agenda, daily. The 2019 Atlantic hurricane season, made worse by a continually warming atmosphere and ocean, has already produced powerful storm events including Hurricane Dorian (which devastated The Bahamas and threatened the Southeastern U.S.) and Tropical Storm Imelda, which flooded Houston for the second time in three years.
A line of onlookers stands before a video camera in Stevens Institute of Technology's S.C. Williams Library, hopeful. Their task: crack a lock that could open, say, a safety deposit box or a bank account or a social security record. Each visitor stares intently into the camera lens. Nothing.
It reads like a horror novel.
A huge "dead zone" has appeared in the Gulf of Mexico — as it does each summer — killing fish and shellfish and closing miles of popular beaches due to unhealthy swimming conditions. Before summer is up, the zone may grow as large as 8,000 square miles: roughly the size of the entire state of New Jersey.
The AR (augmented reality) technology that fuels interactive games like Pokemon Go requires powerful, fast-moving software that can rapidly, continuously create complex, changing three-dimensional scenes, on the fly — often with only the computing power of a single phone or tablet device to tap.
It was inevitable, in a digital era, that AI would eventually come to the NBA.
And the leading-edge technology it uses has a close Stevens connection.
Ureteral stents present a painful, longstanding design problem: how to develop a thin, strong device that works to accommodate urinary flow within the body while also preventing dangerous infection and calcification — and remaining easily retractable.
As high school classmates, Stevens students Mary McKeon '19 and senior Nicholas Gattuso often volunteered together, teaching students with disabilities key transitional skills those students would require to move into mainstream life after school.
Relying on worksheets and other simplistic materials, they sometimes wondered how new technologies could supplement and improve that educational experience.
"I started thinking, even then, about how we could do something like that," says McKeon. "We'd talk about it."
Yanxia Lin jokingly calls the four two-by-one-foot rectangular trays of canvas soaked in water and covered with thin green film her "babies".
But these deceptively simple-looking trays may soon point the way to greener vehicles, school buildings and factories for us all.
