indianapolis, indiana — Semiconductors, or microchips, are critical to almost everything electronic used in the modern world. In 1990, the United States produced about 40% of the world’s semiconductors. As manufacturing migrated to Asia, U.S. production fell to about 12%.  

“During COVID, we got a wake-up call. It was like [a] Sputnik moment,” explained Mark Lundstrom, an engineer who has worked with microchips much of his life. 

The 2020 global coronavirus pandemic slowed production in Asia, creating a ripple through the global supply chain and leading to shortages of everything from phones to vehicles. Lundstrom said increasing U.S. reliance on foreign chip manufacturers exposed a major weakness. 

“We know that AI is going to transform society in the next several years, it requires extremely powerful chips. The most powerful leading-edge chips.” 

Today, Lundstrom is the acting dean of engineering at Purdue University in Lafayette, Indiana, a leader in cutting-edge semiconductor development, which has new importance amid the emerging field of artificial intelligence. 

“If we fall behind in AI, the consequences are enormous for the defense of our country, for our economic future,” Lundstrom told VOA. 

Amid the buzz of activity in a laboratory on Purdue’s campus, visitors can get a vision of what the future might look like in microchip technology. 

“The key metrics of the performance of the chips actually are the size of the transistors, the devices, which is the building block of the computer chips,” said Zhihong Chen, director of Purdue’s Birck Nanotechnology Center, where engineers work around the clock to push microchip technology into the future. 

“We are talking about a few atoms in each silicon transistor these days. And this is what this whole facility is about,” Chen said. “We are trying to make the next generation transistors better devices than current technologies. More powerful and more energy-efficient computer chips of the future.” 

Not just RVs anymore

Because of Purdue’s efforts, along with those on other university campuses in the state, Indiana believes it’s an attractive location for manufacturers looking to build new microchip facilities. 

“Purdue University alone, a top four-ranked engineering school, offers more engineers every year than the next top three,” said Eric Holcomb, Indiana’s Republican governor. “When you have access to that kind of talent, when you have access to the cost of doing business in the state of Indiana, that’s why people are increasingly saying, Indiana.” 

Holcomb is in the final year of his eight-year tenure in the state’s top position. He wants to transform Indiana beyond the recreational vehicle, or “RV capital” of the country.  

“We produce about plus-80% of all the RV production in North America in one state,” he told VOA. “We are not just living up to our reputation as being the number one manufacturing state per capita in America, but we are increasingly embracing the future of mobility in America.” 

Holcomb is spearheading an effort to make Indiana the next great technology center as the U.S. ramps up investment in domestic microchip development and manufacturing.  “If we want to compete globally, we have to get smarter and healthier and more equipped, and we have to continue to invest in our quality of place,” Holcomb told VOA in an interview. 

His vision is shared by other lawmakers, including U.S. Senator Todd Young of Indiana, who co-sponsored the bipartisan CHIPS and Science Act, which commits more than $50 billion in federal funding for domestic microchip development. 

‘We are committed’

Indiana is now home to one of 31 designated U.S. technology and innovation hubs, helping it qualify for hundreds of millions of dollars in grants designed to attract technology-driven businesses. 

“The signal that it sends to the rest of the world [is] that we are in it, we are committed, and we are focused,” said Holcomb. “We understand that economic development, economic security and national security complement one another.” 

Indiana’s efforts are paying off. 

In April, South Korean microchip manufacturer SK Hynix announced it was planning to build a $4 billion facility near Purdue University that would produce next-generation, high-bandwidth memory, or HBM chips, critical for artificial intelligence applications.  

The facility, slated to start operating in 2028, could create more than 1,000 new jobs. While U.S. chip manufacturer SkyWater also plans to invest nearly $2 billion in Indiana’s new LEAP Innovation District near Purdue, the state recently lost bidding to host chipmaker Intel, which selected Ohio for two new factories. 

“Companies tend to like to go to locations where there is already that infrastructure, where that supply chain is in place,” Purdue’s Lundstrom said. “That’s a challenge for us, because this is a new industry for us. So, we have a chicken-and- egg problem that we have to address, and we are beginning to address that.” 

Lundstrom said the CHIPS and Science Act and the federal money that comes with it are helping Indiana ramp up to compete with other U.S. locations already known for microchip development, such as Silicon Valley in California and Arizona. 

What could help Indiana gain an edge is its natural resources — plenty of land and water, and regular weather patterns, all crucial for the sensitive processes needed to manufacture microchips at large manufacturing centers.

FORT LAUDERDALE, Fla. — South Florida researchers trying to prevent predatory fish from devouring laboratory-grown coral are grasping at biodegradable straws in an effort to restore what some call the rainforest of the sea.

Scientists around the world have been working for years to address the decline of coral reef populations. Just last summer, reef rescue groups in South Florida and the Florida Keys were trying to save coral from rising ocean temperatures. Besides working to keep existing coral alive, researchers have also been growing new coral in labs and then placing them in the ocean.

But protecting the underwater ecosystem that maintains more than 25% of all marine species is not easy. Even more challenging is making sure that coral grown in a laboratory and placed into the ocean doesn’t become expensive fish food.

Marine researcher Kyle Pisano said one problem is that predators like parrot fish attempt to bite and destroy the newly transplanted coral in areas like South Florida, leaving them with less than a 40% survival rate. With projects calling for thousands of coral to be planted over the next year and tens of thousands of coral to be planted over the next decade, the losses add up when coral pieces can cost more than $100 each.

Pisano and his partner, Kirk Dotson, have developed the Coral Fort, claiming the small biodegradable cage that’s made in part with drinking straws boosts the survival rate of transplanted coral to over 90%.

“Parrot fish on the reef really, really enjoy biting a newly transplanted coral,” Pisano said. “They treat it kind of like popcorn.”

Fortunately the fish eventually lose interest in the coral as it matures, but scientists need to protect the coral in the meantime. Stainless steel and PVC pipe barriers have been set up around transplanted coral in the past, but those barriers needed to be cleaned of algae growth and eventually removed.

Pisano had the idea of creating a protective barrier that would eventually dissolve, eliminating the need to maintain or remove it. He began conducting offshore experiments with biodegradable coral cages as part of a master’s degree program at Nova Southeastern University. He used a substance called polyhydroxyalkanoate, a biopolymer derived from the fermentation of canola oil. PHA biodegrades in ocean, leaving only water and carbon dioxide. His findings were published last year.

The coral cage consists of a limestone disc surrounded by eight vertical phade brand drinking straws, made by Atlanta-based WinCup Inc. The device doesn’t have a top, Pisano said, because the juvenile coral needs sunlight and the parrot fish don’t generally want to position themselves facing downward to eat.

Dotson, a retired aerospace engineer, met Pisano through his professor at Nova Southeastern, and the two formed Reef Fortify Inc. to further develop and market the patent-pending Coral Fort. The first batch of cages were priced at $12 each, but Pisano and Dotson believe that could change as production scales up.

Early prototypes of the cage made from phade’s standard drinking straws were able to protect the coral for about two months before dissolving in the ocean, but that wasn’t quite long enough to outlast the interest of parrot fish. When Pisano and Dotson reached out to phade for help, the company assured them that it could make virtually any custom shape from its biodegradable PHA material.

“But it’s turning out that the boba straws, straight out of the box, work just fine,” Dotson said.

Boba straws are wider and thicker than normal drinking straws. They’re used for a tea-based drink that includes tapioca balls at the bottom of the cup. For Pisano and Dotson, that extra thickness means the straws last just long enough to protect the growing coral before harmlessly disappearing.

Reef Fortify is hoping to work with reef restoration projects all over the world. The Coral Forts already already being used by researchers at Nova Southeastern and the University of Miami, as well as Hawaii’s Division of Aquatic Resources.

Rich Karp, a coral researcher at the University of Miami, said they’ve been using the Coral Forts for about a month. He pointed out that doing any work underwater takes a great deal of time and effort, so having a protective cage that dissolves when it’s no longer needed basically cuts their work in half.

“Simply caging corals and then removing the cages later, that’s two times the amount of work, two times the amount of bottom time,” Karp said. “And it’s not really scalable.”

Experts say coral reefs are a significant part of the oceanic ecosystem. They occupy less than 1% of the ocean worldwide but provide food and shelter to nearly 25 percent of sea life. Coral reefs also help to protect humans and their homes along the coastline from storm surges during hurricanes.
