Most researchers hope they will be the one to discover the next big breakthrough advance for society, like finding a cure for cancer or climate change. But groundbreaking ideas usually mean taking risks in innovation, which calls for scientists and engineers who aren’t afraid to dream big.

That’s exactly what the American Institute of Chemical Engineers (AIChE) is looking for when it awards the Langer Prize for Innovation and Entrepreneurial Excellence to researchers pursuing “blue sky” ideas, like UD’s own Aditya Kunjapur.

Kunjapur, an assistant professor in the Department of Chemical and Biomolecular Engineering, has been awarded the 2021 AIChE Langer Prize to help transition bacteria-based technology that his lab has developed toward the marketplace. He marks only the third recipient of this grant, which is awarded to original ideas that have a real promise of providing valuable contributions to society.

“There are a lot of things that I like about what AIChE has done by creating this particular award. One of those is that they are recognizing that entrepreneurship is really important,” Kunjapur said. “This is true in general for science, but even more so in the current environment where academic discoveries and inventions related to biotechnology need to be translated to help make a difference in people’s lives.”

Kunjapur’s work has focused on engineering bacteria to perform a wide array of functions, from producing fuels and chemicals to treating or preventing disease. In his lab, which was launched at UD only three years ago, he is focusing on creating and harnessing new chemical building blocks using genetically engineered bacteria. In the case of the project supported by the Langer Prize, Kunjapur’s Lab is exploring whether bacteria can produce amino acids that will elicit a stronger immune response, which could lead to applications in vaccines or as immunotherapies.

“What we’re doing is trying to put something onto those proteins that says, ‘Hey, look at me!’ to the immune system,” Kunjapur said. “Our community of synthetic biologists has gotten so good at changing the genetics of a microbe. You’d think — especially during a global pandemic — that we might have a lot of tools that would be relevant. In fact, we do. And my colleagues have done a lot of great work in this area.”

With antibiotic resistance on the rise, having better vaccine candidates to battle troublesome bacteria would decrease our reliance on finding new antibiotics. Now, he’s exploring whether synthetic biology tools can lead to the design of a vaccine that could work against bacteria for which there currently are no vaccines.

“This project so far is the work of one really outstanding graduate student,” Kunjapur said, giving credit to Neil Butler, a chemical engineering graduate student. “It’s been his initiative from day one, and his work played a huge role in earning this prize.”

It can be challenging to fund “blue sky” ideas because those out-of-the-box ideas are also often a higher risk to explore. That’s why it’s notable that the $75,000 stipend connected to the award is completely unrestricted. Kunjapur said Langer Prize funding will allow his lab to further explore commercialization of their discoveries, contract out more research, accelerate the technology and continue conversations with companies to learn about their needs.

“This funding will allow us to begin to perform higher-risk, more expensive experiments that are normally difficult to fit in the budget of a new lab,” Butler said. “I’m excited to push these directions forward.”

That success in the lab, as well as support from the Langer Prize, has allowed Kunjapur’s group to seek a new entrepreneurial postdoctoral fellow with experience in protein engineering, next-generation sequencing and immunology to start in mid-2022. Interested applicants should reach out to Kunjapur directly before Friday, Dec. 31.

The Kunjapur Lab has been working on this project since its inception, and has also received research funding from the National Science Foundation. More recent NSF support came from Horn Entrepreneurship’s NSF I-Corps Sites Program for commercial translation of their work. Through that program, Butler participated in training and conducted interviews with customers and companies that could find value in their synthetic biology-based technology.

“Using synthetic biology, we believe bacteria can synthesize proteins that are better targets for the immune system,” Butler said. “Innovative alternatives to traditional vaccination methods should be pursued.”

The Langer Prize itself, like Kunjapur’s lab at UD, is relatively new. Named after Robert S. Langer, one of 12 Institute professors at the Massachusetts Institute of Technology, the prize is awarded to entrepreneurial researchers aiming to address challenges in a variety of industries. The award, first granted in 2019, comes with unrestricted seed funding “to tackle high-risk, high-impact challenges with the potential of achieving game-changing innovations.”

Kunjapur, who finished his postdoctoral work at Harvard Medical School in 2018, is only the third honoree of the Langer Prize, which is intended for early-career researchers demonstrating entrepreneurial excellence in innovations. He joined the UD faculty in 2018, and since then has been named an Emerging Leaders in Biosecurity Initiative Fellow (in 2019) and to the “35 Under 35” class of the American Institute of Chemical Engineers (in 2020).

Langer and Kunjapur have more in common than just this award. Kunjapur was a student in MIT’s chemical engineering department and could have pursued working for him in the esteemed Langer Lab, he said.

“At the time, I just didn’t think of myself as being that interested in drug delivery or biomedical research,” Kunjapur said as he recalled a talk by Langer that he attended as a first-year grad student. Listening to Langer’s story of his own professional journey helped Kunjapur realize that working in a well-established field like the oil and gas industry would mean that success would revolve around truly incremental changes — like making a process just 0.00001% better. Inspired by Langer’s decision to turn down the oil and gas industry for uncharted waters, Kunjapur found himself on his own innovative journey. 

Now, small scientific ventures chasing “blue sky” ideas like those being explored in Kunjapur’s lab are on the front lines of societal leaps and bounds in the face of a global pandemic. Start-up technologies with academic roots have been instrumental to the success of the Moderna and Pfizer vaccines for COVID-19.

“It’s important to just try things that are a little outside of the box or higher risk,” Kunjapur said. “Even though we have this kind of aging infrastructure for scientific funding, society is still capable of doing things on a remarkable scale and pace. It’s just incredible what progress in biotechnology has been achieved in the last three years.”

Low Iron Levels In Blood Could Trigger Long COVID: Study

People with inadequate iron levels in their blood due to a COVID-19 infection could be at greater risk of long COVID.

A new study indicates that problems with iron levels in the bloodstream likely trigger chronic inflammation and other conditions associated with the post-COVID phenomenon. The findings, published on March 1 in Nature Immunology, could offer new ways to treat or prevent the condition.

Long COVID Patients Have Low Iron Levels

Researchers at the University of Cambridge pinpointed low iron as a potential link to long-COVID symptoms thanks to a study they initiated shortly after the start of the pandemic. They recruited people who tested positive for the virus to provide blood samples for analysis over a year, which allowed the researchers to look for post-infection changes in the blood. The researchers looked at 214 samples and found that 45 percent of patients reported symptoms of long COVID that lasted between three and 10 months.

In analyzing the blood samples, the research team noticed that people experiencing long COVID had low iron levels, contributing to anemia and low red blood cell production, just two weeks after they were diagnosed with COVID-19. This was true for patients regardless of age, sex, or the initial severity of their infection.

According to one of the study co-authors, the removal of iron from the bloodstream is a natural process and defense mechanism of the body.

But it can jeopardize a person’s recovery.

When the body has an infection, it responds by removing iron from the bloodstream. This protects us from potentially lethal bacteria that capture the iron in the bloodstream and grow rapidly. It’s an evolutionary response that redistributes iron in the body, and the blood plasma becomes an iron desert,” University of Oxford professor Hal Drakesmith said in a press release. “However, if this goes on for a long time, there is less iron for red blood cells, so oxygen is transported less efficiently affecting metabolism and energy production, and for white blood cells, which need iron to work properly. The protective mechanism ends up becoming a problem.”

The research team believes that consistently low iron levels could explain why individuals with long COVID continue to experience fatigue and difficulty exercising. As such, the researchers suggested iron supplementation to help regulate and prevent the often debilitating symptoms associated with long COVID.

It isn’t necessarily the case that individuals don’t have enough iron in their body, it’s just that it’s trapped in the wrong place,” Aimee Hanson, a postdoctoral researcher at the University of Cambridge who worked on the study, said in the press release. “What we need is a way to remobilize the iron and pull it back into the bloodstream, where it becomes more useful to the red blood cells.”

The research team pointed out that iron supplementation isn’t always straightforward. Achieving the right level of iron varies from person to person. Too much iron can cause stomach issues, ranging from constipation, nausea, and abdominal pain to gastritis and gastric lesions.

1 in 5 Still Affected by Long COVID

COVID-19 has affected nearly 40 percent of Americans, with one in five of those still suffering from symptoms of long COVID, according to the U.S. Centers for Disease Control and Prevention (CDC). Long COVID is marked by health issues that continue at least four weeks after an individual was initially diagnosed with COVID-19. Symptoms can last for days, weeks, months, or years and may include fatigue, cough or chest pain, headache, brain fog, depression or anxiety, digestive issues, and joint or muscle pain.

February Employment Situation

The establishment data from the BLS showed a 275,000 increase in payroll employment for February, outpacing the 230,000 average over the previous 12 months. The payroll data for January and December were revised down by a total of 167,000. The private sector added 223,000 new jobs, the largest gain since May of last year.

Temporary help services employment continues a steep decline after a sharp post-pandemic rise.

Average hours of work increased from 34.2 to 34.3. The increase, along with the 223,000 private employment increase led to a hefty increase in total hours of 5.6% at an annualized rate, also the largest increase since May of last year.

The establishment report, once again, beat “expectations;” the WSJ survey of economists was 198,000. Other than the downward revisions, mentioned above, another bit of negative news was a smallish increase in wage growth, from $34.52 to $34.57.

The household survey shows that the labor force increased 150,000, a drop in employment of 184,000 and an increase in the number of unemployed persons of 334,000. The labor force participation rate held steady at 62.5, the employment to population ratio decreased from 60.2 to 60.1 and the unemployment rate increased from 3.66 to 3.86. Remember that the unemployment rate is the number of unemployed relative to the labor force (the number employed plus the number unemployed). Consequently, the unemployment rate can go up if the number of unemployed rises holding fixed the labor force, or if the labor force shrinks holding the number unemployed unchanged. An increase in the unemployment rate is not necessarily a bad thing: it may reflect a strong labor market drawing “marginally attached” individuals from outside the labor force. Indeed, there was a 96,000 decline in those workers.

Earlier in the week, the BLS announced JOLTS (Job Openings and Labor Turnover Survey) data for January. There isn’t much to report here as the job openings changed little at 8.9 million, the number of hires and total separations were little changed at 5.7 million and 5.3 million, respectively.

As has been the case for the last couple of years, the number of job openings remains higher than the number of unemployed persons.

Also earlier in the week the BLS announced that productivity increased 3.2% in the 4th quarter with output rising 3.5% and hours of work rising 0.3%.

The bottom line is that the labor market continues its surprisingly (to some) strong performance, once again proving stronger than many had expected. This strength makes it difficult to justify any interest rate cuts soon, particularly given the recent inflation spike.

Spread & Containment

Another beloved brewery files Chapter 11 bankruptcy

The beer industry has been devastated by covid, changing tastes, and maybe fallout from the Bud Light scandal.

Published

on

Before the covid pandemic, craft beer was having a moment. Most cities had multiple breweries and taprooms with some having so many that people put together the brewery version of a pub crawl.

It was a period where beer snobbery ruled the day and it was not uncommon to hear bar patrons discuss the makeup of the beer the beer they were drinking. This boom period always seemed destined for failure, or at least a retraction as many markets seemed to have more craft breweries than they could support.

The pandemic, however, hastened that downfall. Many of these local and regional craft breweries counted on in-person sales to drive their business. 

And while many had local and regional distribution, selling through a third party comes with much lower margins. Direct sales drove their business and the pandemic forced many breweries to shut down their taprooms during the period where social distancing rules were in effect.

During those months the breweries still had rent and employees to pay while little money was coming in. That led to a number of popular beermakers including San Francisco's nationally-known Anchor Brewing as well as many regional favorites including Chicago’s Metropolitan Brewing, New Jersey’s Flying Fish, Denver’s Joyride Brewing, Tampa’s Zydeco Brew Werks, and Cleveland’s Terrestrial Brewing filing bankruptcy.

Some of these brands hope to survive, but others, including Anchor Brewing, fell into Chapter 7 liquidation. Now, another domino has fallen as a popular regional brewery has filed for Chapter 11 bankruptcy protection.

Overall beer sales have fallen.

Covid is not the only reason for brewery bankruptcies

While covid deserves some of the blame for brewery failures, it's not the only reason why so many have filed for bankruptcy protection. Overall beer sales have fallen driven by younger people embracing non-alcoholic cocktails, and the rise in popularity of non-beer alcoholic offerings,

Beer sales have fallen to their lowest levels since 1999 and some industry analysts

"Sales declined by more than 5% in the first nine months of the year, dragged down not only by the backlash and boycotts against Anheuser-Busch-owned Bud Light but the changing habits of younger drinkers," according to data from Beer Marketer’s Insights published by the New York Post.

Bud Light parent Anheuser Busch InBev (BUD) faced massive boycotts after it partnered with transgender social media influencer Dylan Mulvaney. It was a very small partnership but it led to a right-wing backlash spurred on by Kid Rock, who posted a video on social media where he chastised the company before shooting up cases of Bud Light with an automatic weapon.

Another brewery files Chapter 11 bankruptcy

Gizmo Brew Works, which does business under the name Roth Brewing Company LLC, filed for Chapter 11 bankruptcy protection on March 8. In its filing, the company checked the box that indicates that its debts are less than $7.5 million and it chooses to proceed under Subchapter V of Chapter 11. 

"Both small business and subchapter V cases are treated differently than a traditional chapter 11 case primarily due to accelerated deadlines and the speed with which the plan is confirmed," USCourts.gov explained. 

Roth Brewing/Gizmo Brew Works shared that it has 50-99 creditors and assets $100,000 and $500,000. The filing noted that the company does expect to have funds available for unsecured creditors. 

The popular brewery operates three taprooms and sells its beer to go at those locations.

"Join us at Gizmo Brew Works Craft Brewery and Taprooms located in Raleigh, Durham, and Chapel Hill, North Carolina. Find us for entertainment, live music, food trucks, beer specials, and most importantly, great-tasting craft beer by Gizmo Brew Works," the company shared on its website.

The company estimates that it has between $1 and $10 million in liabilities (a broad range as the bankruptcy form does not provide a space to be more specific).

Gizmo Brew Works/Roth Brewing did not share a reorganization or funding plan in its bankruptcy filing. An email request for comment sent through the company's contact page was not immediately returned.
