Self-Built Protein Coatings Could Improve Biomedical Devices
Fouling is a natural phenomenon that describes the tendency of proteins in water to adhere to nearby surfaces. It’s what causes unwanted deposits of protein to form during some food production or on biomedical implants, causing them to fail. Using her expertise in developing bio-inspired materials for use in human health, R. Helen Zha, an assistant professor of chemical and biological engineering will harness this process found in nature to develop a versatile and accessible approach for modifying solid surfaces. With the support of a more than $592,000 National Science Foundation Faculty Early Career Development (CAREER) grant, Zha will use silk fibroin — a protein that naturally assembles itself — to grow a nanoscale film on the surface of an object. This approach only requires a beaker, water, salt, and the protein, which Zha said makes it biocompatible, safe, ecofriendly, and accessible beyond the walls of a lab. Zha has demonstrated that this approach can work and, in some cases, even increase the therapeutic benefits of an implant. In research published in ACS Biomaterials Science & Engineering, Zha collaborated with Ryan Gilbert, a professor of biomedical engineering at Rensselaer, to modify the surface of a fibrous scaffold that was developed by Gilbert’s lab in order to encourage the growth of neurites at the site of nerve damage. The importance of this research could expand beyond the protein Zha and her lab are working with. This approach, she explained, could be applied to any number of proteins and macromolecules.
Wastewater Hazards in Southwest Florida Spark Environmental Concerns Across the State and Beyond
Over the last week hundreds of millions of gallons of wastewater have spewed from a former fertilizer plant in Piney Point, Florida, which was abandoned in 2001 and taken over in 2006 by the Florida Department of Environmental Protection. The location is adjacent to Tampa Bay, a 400-square-mile body of water that separates Tampa, Clearwater and St. Petersburg and is full of fish, crabs, seagrass, dolphins, manatees and seabirds of every kind. The state plans to close Piney Point, scientists are trying to forecast what comes next and environmentalists fear algal blooms and fish kills (also known as fish die-offs). “There are hundreds if not thousands of these waste storage ponds in the United States and each one is a ticking time bomb,” says Villanova University’s Metin Duran, PhD, an expert on the biological processes of environmental engineering, including public health microbiology and biological processes for waste management. “The last major disaster was in December 2008, when a 40-acre pond used by Tennessee Valley Authority for the coal-burning Kingston Fossil Plant collapsed. The aftermath included damage to the area’s ecosystem and lawsuits.” Regulations regarding waste storage ponds are at the state level, and they aren’t very strict, says Dr. Duran. “Though there are strict design and groundwater monitoring requirements to ensure waste does not cause groundwater pollution, these waste impoundments are prone to have issues under extreme weather events, such as heavy rains. With the increased frequency of such events recently, there is a risk that more of such may fail.” Dr. Duran adds that it can be difficult to predict short- and long-term effects of the Florida case, but the reported low-level radioactive contamination could cause major damage to aquatic life and properties—and that phosphorous and nitrogen would cause eutrophication in Tampa Bay as well.
As President Biden Lays Out Infrastructure Plan, Experts Available to Discuss Proposals
As President Joe Biden lays out his plan for improving the nation's infrastructure, experts from Rensselaer Polytechnic Institute are available to discuss the ways in which proposed projects could affect shipping and delivery of goods, congestion in cities, and emissions in the environment, among other topics. José Holguín-Veras, the director of the Center for Infrastructure, Transportation, and the Environment at Rensselaer, and Cara Wang, an associate professor of civil and environmental engineering at Rensselaer, are leading experts in the role of infrastructure on freight and transportation systems, and the environmental impacts of both. Their research focuses on improving transportation and freight systems in order to increase efficiency, reduce traffic congestion and, in turn, reduce vehicle emissions. Holguín-Veras and Wang can also discuss what their research has uncovered that could guide policy makers as new projects are planned.
Solar geoengineering - it’s a topic that has caused an ethical lightening storm in the science community. The concept is complex. Should the world take on the crisis of climate change by attempting to artificially attempting to cool the earth? It’s an idea that has the National Academies of Sciences, Engineering and Medicine seeking a billion dollars in the next five years to investigate the theory. It’s a topic that is somewhat controversial, and journalists are looking to leading experts from across America for expert insight, opinion and perspective. Prakash Kashwan, a political scientist at the University of Connecticut, said he felt the report could have better emphasized the seriousness of some concerns over others. Uncertainties about the impacts of solar geoengineering on global weather patterns have the potential to affect some regions of the world more severely than others, he pointed out. Some experts have raised concerns about potential effects of geoengineering on monsoon rainfall in parts of Asia and Africa, he said. More than 2 billion people around the world rely on these rainfall patterns to support their water and agricultural needs. These kinds of issues should be given special weight, Kashwan suggested. "Some uncertainties are much more highly consequential for the global society, and especially for the poor and vulnerable," he told E&E News. Kashwan also reiterated concerns about potential political effects. While the report makes clear that geoengineering is not a substitute for climate mitigation, he suggests that this doesn't necessarily prevent policymakers from using it in that way. "The problem is the extent to which researchers are really helpless in deciding how research is used in the political system," he said. "That part has yet to be fully appreciated." Kashwan suggests that more dialogue might be warranted before funding a national research program, with greater input from both the international community and political experts who can weigh in on the ways that geoengineering research might affect political decisions. March 26, Scientific American It's a captivating idea – but it could have political, social and ethical consequences. Dr. Kashwan has also been interviewed by The New York Times. If you are a journalist looking to learn more about solar geoengineering, its possibilities and the reasons some scientists are worried – then let us help with your coverage.

Power Grid Expert Weighs in on Texas Outages And How to Build a Better System
Having run countless simulations and experiments aimed at building a more resilient power grid, Luigi Vanfretti is well acquainted with the weaknesses in the nation’s current system. This expertise was recently featured in a report about the factors that caused massive, ongoing power outages in Texas. Frozen well heads, gas pipes, and other factors contributed to a “perfect storm” of conditions, Vanfretti said. Some politicians and pundits have floated the notion that the catastrophe was primarily due to frozen wind turbines, but according to Vanfretti, an associate professor of electrical, computer, and systems engineering at Rensselaer Polytechnic Institute, the problem is far more complex. Additionally, the electrical grid in Texas is unique in that it has limited connections to neighboring states, which means there are limitations to how much assistance it can receive during a crisis. “It’s about the ability to route the power,” Vanfretti recently told the Times Union. Vanfretti is an expert in power grid modeling, simulation, stability, and control. His research focuses on creating a smarter, cleaner, more reliable power grid that is capable of integrating renewable energy. Within his Analysis Laboratory for Synchrophasor and Electrical Energy Technology (ALSET) Lab, Vanfretti and his team model the power grid and run simulations in order to develop, test, and improve smart inverters, software, and hardware that will be needed to create the smart grid of the future. You can watch him discuss his research here. Vanfretti is available to speak about what contributed to the devastating outages in Texas, as well as the changes and research necessary to create a more resilient power system.
Big Data Offers New Insights Into Biological Components of Autism Spectrum Disorder
In recently published research, blood sample analysis showed that mothers of children with autism spectrum disorder (ASD) had several significantly different metabolite levels two to five years after they gave birth when compared to mothers of typically developing children. The research team behind this finding was Juergen Hahn, the head of the Department of Biomedical Engineering at Rensselaer Polytechnic Institute, a pioneer in the use of big data to investigate biological components of ASD. Hahn is available to discuss the findings of his recent research, as well as his overall approach to studying autism. Previously, Hahn discovered patterns with certain metabolites in the blood of children with autism that can be used to successfully predict diagnosis. He has since successfully applied his big data approach to evaluating potential ASD treatments. For the recent paper, which Hahn co-authored, his team analyzed blood samples from 30 mothers whose young children had been diagnosed with ASD and 29 mothers of typically developing children. They found differences in several metabolite levels between the two groups of mothers. While the samples analyzed were taken two to five years after pregnancy, these research findings raise the question of whether or not the differences in metabolites may have been present during pregnancy as well. In addition to his specific findings, Hahn is available to discuss the use of big data in improving society's understanding of the biological mechanisms at work in ASD.
Japan Society Presents When Practice Becomes Form: Carpentry Tools from Japan
Installation view at the Takenaka Carpentry Tools Museum, Kobe, Japan. On the occasion of the 50th anniversary of Japan Society’s landmark building, the institution is pleased to present the new exhibition, When Practice Becomes Form: Carpentry Tools from Japan. The exhibition celebrates the spirit of architecture and craftsmanship through Japanese woodworking tools as well as architectural patterns and various models. The site-specific installation, conceived by the esteemed contemporary architect Sou Fujimoto in collaboration with Brooklyn-based Popular Architecture, reinterprets major themes from the exhibition and is in dialogue with the gallery’s spaces, highlighting an enduring connection between traditional Japanese wooden construction and modern architecture. Featuring hand tools and joinery techniques that have been used for hundreds of years to build Japan’s wooden architectural masterpieces (from temples and shrines to teahouses and bridges), the exhibition unpacks how the intangible qualities of craftsmanship, such as consummate experience, knowledge, and the honed skills of master carpenters, have been transformed into significant forms of architecture. A diverse array of tools—planes, chisels, saws—have played an important role in the development of architecture in Japan’s history, and this philosophy extends to Japan’s cultural heritage today. Integral to the process of making by master carpenters (tōryo) is their extensive knowledge of the local environment and of wood as a material. Using natural resources and learning from their predecessors’ practices, they construct buildings using a refined methodology. Their philosophy of sustainability—for example, joinery can be restored or repaired as needed by future craftspeople—has been handed down over generations. Themes emerging from the exhibition have been interpreted by the internationally acclaimed architect Sou Fujimoto. His firm, Sou Fujimoto Architects, is based in Paris and Tokyo, and has been selected as site design producer for the 2025 World Exposition in Osaka, Japan. Fujimoto has designed the Serpentine Gallery pavilion in London (2013) among other internationally recognized projects. For this exhibition, Fujimoto has worked with Popular Architecture to explore the coexistence of nature and architecture. “Japan Society has been a home of cultural exchange, and a meeting place of past and present. In this exhibition, traditional Japanese craftsmanship is revealed in a new light by the design of contemporary architect Sou Fujimoto, and it becomes a precious educational opportunity to learn from this history,” says Yukie Kamiya, Japan Society Gallery Director. The building of Japan Society’s headquarters, designed by the architect Junzo Yoshimura (1908–1997), a major figure in 20th century Japanese architecture, opened to the public in 1971, becoming New York City’s first permanent structure designed by a Japanese citizen. It will commemorate its 50th anniversary in 2021. The building resides on land donated by John D. Rockefeller 3rd (1906–1978), former President and Chairman of Japan Society, who sought to revitalize the organization’s activities after World War II. Rockefeller 3rd and Yoshimura first met in Japan in 1951, and their friendship for over two decades resulted in Japan Society’s current building in Manhattan. Since its opening, the building has continued to serve as the central platform for the interexchange of ideas, knowledge, and innovation between the U.S. and Japan within a global context. In 2011, the building was designated landmark status by the New York City Landmarks Preservation Commission. When Practice Becomes Form: Carpentry Tools from Japan explores the connections between techniques, tools, and forms from traditional practices in Japanese carpentry and contemporary design perspectives. Paying homage to Japan Society’s building, where the arts and cultures of Japan and the United States intersect, this exhibition delves into the artistry and craftsmanship of architectural practice. Complementing the exhibition is a series of related public programs, including lectures, a hands-on workshop, and gallery tours. A digital publication illustrated and designed by Nathan Antolik further expands upon the exhibition. This exhibition is organized by Japan Society in collaboration with Takenaka Carpentry Tools Museum, Japan. The exhibition design is by Sou Fujimoto, in collaboration with Popular Architecture as local architect. About Sou Fujimoto Born in Hokkaido in 1971, Sou Fujimoto graduated from the Department of Architecture, Faculty of Engineering at Tokyo University and established Sou Fujimoto Architects in 2000. He has won several international competitions, including his recent 1st prize for the 2014 International Competition for the Second Folly of Montpellier, France ("L'Arbre Blanc"). In 2019, he was selected as the master architect for the Tsuda University Kodaira Campus Master Plan development. Among his notable projects are the annual summer pavilion for the Serpentine Gallery in London (2013)—the youngest architect to receive the commission; House NA in Tokyo (2012); Musashino Art University Museum & Library (2010); and House N (2008). In 2012, he was part of the Japanese team that won a Golden Lion award for Best National Participation at the Venice Architecture Biennale for their design of alternative housing concepts for homes destroyed by the 2011 tsunami. Most recently, he was selected as site producer for the 2025 World Exposition in Osaka, Japan.

How the Biden Administration Can Help Save the Planet
With the inauguration of Joseph R. Biden as the 46th president of the United States came a slew of executive orders—and perhaps most notably America's reentry into the Paris Climate Accord. After the Obama administration joined the largest global cooperative agreement to limit the emission of dangerously climate-altering greenhouse gasses in 2015, the U.S. withdrew in 2017 under former president Donald Trump. Villanova University biology professor Samantha Chapman, PhD, studies how "blue carbon" solutions, like the restoration of wetlands, can contribute to slowing the harmful impact of climate change on the planet. Recently, Dr. Chapman broke down the top three things the Biden administration must do to save the planet, since we are, as she puts it, "close to some scary tipping points." #1: Pressure Brazil’s President Bolsonaro to stop the devastation of the Amazon. "The Amazon Rainforest regulates our global climate. It is imperative that through diplomacy and aid, we incentivize developing countries to preserve their intact lands and biodiversity. We can't do this without helping local communities incentivize the people living in these places to save these lands. Road building in forests is a huge cause of our planet's downward slope." #2: Invest in restoration of natural ecosystems. "We must invest resources into coastal wetlands and forests, here and abroad. USAID could be partially retooled in partnership with the United Stated Geological Survey (USGS), which already does this. These natural ecosystems will serve as natural climate solutions and be harbors for threatened species and nice places for humans to recreate. We must restore the opportunity for nature to re-invoke the necessary feedbacks that make the ecosystems work. Sometimes this involves complicated engineering, sometimes it is simpler and means giving nature space to restore. We're trying both." #3: Find ways to make people feel connected to land and nature—and value it. "This is a vague one and not one that I'm sure any administration can do. The pandemic has given me hope on this—I see so many more people out hiking, fishing, walking, and hanging out in parks. When time comes for voting on taxes, people have to remember that these state parks and preserves and even neighborhood parks cost money to staff and preserve. The U.S. has incredible land and nature and yet, in my experience, Americans value and understand it less than other countries. Some of that has to do with our frontier history. We can learn from Native Americans. Appointing Representative Deb Haaland as the secretary of the interior is one good step the Biden administration has taken in this direction." Dr. Chapman emphasizes that despite the uphill battle ahead, she remains hopeful. "Left to heal and helped to heal, the ecosystem processes that sustain our lives and those of the other amazing organisms on our planet can be restored," she notes. "Good things are happening. They just need to happen at a much larger scale."
On January 06, America watched with shock as a mob of protesters stormed the gates in Washington, D.C. and invaded the Capitol buildings. For hours, the rioters looted and occupied America’s halls of power and though some were apprehended, many found a way to get out and get back home avoiding arrest. However, media coverage was substantial and some of the protesters were even bold enough to be caught posing for social media. Slowly, authorities are tracking them down, and Dr. Derek Riley, an expert at Milwaukee School of Engineering (MSOE) in the areas of computer science and deep learning, has been explaining how artificial intelligence (AI) technology that’s taught at MSOE is capable of enabling law enforcement's efforts to identify individuals from pictures. "With these AI systems, we’ll show it example photos and we’ll say, 'OK, this is a nose, this is an ear, this is Billy, this is Susie,'" Riley said. "And over lots and lots of examples and a kind of understanding if they guess right or wrong, the algorithm actually tunes itself to get better and better at recognizing certain things." Dr. Riley says this takes huge amounts of data and often needs a supercomputer—like MSOE's "Rosie"— to process it. To get a computer or software to recognize a specific person takes more fine-tuning, Riley says. He says your smartphone may already do this. "If you have a fingerprint scan or facial recognition to open up your phone, that’s exactly what’s happening," Riley said. "So, they’ve already trained a really large model to do all the basic recognition, and then you provide a device with a fingerprint scanning or pictures of your face at the end to be able to fine-tune that model to recognize exactly who you are." Riley says this technology isn't foolproof—he says human intelligence is needed at every step. He added we might be contributing to the data sources some of the technology needs by posting our pictures to social media. "Folks are uploading their own images constantly and that often is the source of the data that is used to train these really, really large systems," Riley said. January 14 – WTMJ, Ch. 4, NBC News The concept of facial recognition and the use of this technology in law enforcement (and several other applications) is an emerging topic – and if you are a reporter looking to cover this topic or speak with an expert, then let us help. Dr. Derek Riley is an expert in big data, artificial intelligence, computer modeling and simulation, and mobile computing/programming. He’s available to speak with media about facial recognition technology and its many uses. Simply click on his icon now to arrange an interview today.
