HANOVER, N.H. — Dartmouth’s Neukom Institute is proud to announce the winners of the 2020 Neukom Institute Literary Arts Awards for speculative fiction:

2020 Neukom Institute Literary Arts Award for Speculative Fiction (Debut)

Cadwell Turnbull, The Lesson (Blackstone Publishing, 2019)

2020 Neukom Institute Literary Arts Award for Speculative Fiction (Open)

Ted Chiang, Exhalation (Knopf, 2019)

“Speculative fiction has always challenged and enlarged our ideas of what the world can be,” said Dan Rockmore, director of the Neukom Institute for Computational Science at Dartmouth. “This year’s winners continue this important tradition and recognize two wondrous and wonderful additions to this vibrant genre.”

In recognition of the relevance of speculative fiction to our time and the vast amount of high quality work being written, the Neukom Awards has also awarded special recognition to We Set the Dark on Fire, by Tehlor Kay Mejia (Katherine Tegen Books, 2019) in the debut category, and The Archive of Alternate Endings, by Lindsey Drager (Dzanc Books, 2019) in the open category.

The book awards were judged by Nebula Award-winner Sam J. Miller, author of The Art of Starving, Blackfish City, Destroy All Monsters and The Blade Between.

Complex Books for Complex Times

The debut winner, The Lesson, by Cadwell Turnbull, tells the story of the tense relationship between residents of the U.S. Virgin Islands and aliens parked over the island group on a multiyear research mission. The book provides a spec-fic twist to the complexities of colonialism, and of interactions between people.

“Few science fiction storylines are more overused than tales of alien first contact and invasion, which makes Cadwell Turnbull’s achievement in The Lesson all the more astonishing,” said Miller. “He’s managed to make it fresh and alive and painfully relevant for a moment where our histories of colonization and exploitation are poised to teach us all some terrible lessons, and we should all be paying attention. It’s the kind of debut that makes me so excited for the future of speculative fiction.”

The open category winner, Exhalation, by Ted Chiang, is a collection of nine stories that address subjects including time travel, alien life and artificial intelligence. In the book, Chiang’s second collection of stories, the author creates devices such as a digital memory and a digital pet to explore the many imaginative alleyways of the spec-fic genre.

“Ted Chiang is simply the greatest living science fiction writer, and each new story of his is cause for celebration. It’s been 17 years since his last collection, and Exhalation is exactly the kind of brain-exploding, superhuman, profoundly human work we need right now. Far and away the best speculative book of the year, and probably the decade. Ted’s stories rewrite the rules of the world and widen the scope of our dreams, and we are all in his debt,” said Miller.

Turnbull and Chiang will participate in an online award event later this month to discuss their works and the speculative fiction genre. Miller and Rockmore will also participate.

In addition to appearing on the panel, the two top award winners will each receive a $5,000 honorarium.

The awards program serves as part of the Neukom Institute’s mission to explore the possibilities of computational science, including the ways in which computational ideas impact society.

Sex differences in COVID-19 outcomes

In a study of more than 10,600 adult patients hospitalized with COVID-19, women had significantly lower odds than men of in-hospital mortality. They also had fewer admissions to the intensive care unit and less need for mechanical ventilation. Women also had significantly lower odds of major adverse events, including acute cardiac injury, acute kidney injury, and venous thromboembolism, according to an article in the peer-reviewed Journal of Women’s Health. Click here to read the article now.

“This comprehensive analysis is the largest study to date that directly assesses the impact of sex on COVID-19 outcomes,” stated Rachel-Maria Brown, MD, Zucker School of Medicine at Hofstra/Northwell, and coauthors. “Our study strongly demonstrates female sex to be associated with lower odds of in-hospital outcomes, major adverse effects and all-cause mortality as compared to male sex after controlling for confounding variables.” The authors propose some of the protective factors that may contribute to these findings.

In the accompanying editorial entitled “Lessons Learned from COVID-19 Sex Disparities,” Annabelle Santos Volgman, MD, Rush University Medical Center, and coauthors, suggest various mechanisms by which female sex may confer a protective advantage against COVID-19 infection. One advantage may be the extra X chromosome, which carries multiple genes responsible for innate and adaptive immunity.

Volgman and coauthors emphasize that “although women have less mortality risk with COVID-19, we need to exercise caution not to send a message to deliver subpar care to women with COVID-19 or decrease measures to prevent their infection. Our evolving knowledge should not reduce attention paid to women admitted for COVID-19.”

UTHSC awarded $1.5 million HRSA grant for sexual assault nurse examiner training

Memphis, Tenn. (June 16, 2021) – The University of Tennessee Health Science Center’s College of Nursing has received a three-year, $1.5 million grant from the Department of Health and Human Services Health Resources and Services Administration (HRSA) to fund a much-needed expansion of Sexual Assault Nurse Examiner (SANE) training and certification in West Tennessee.

SANE programs are designed to train nurses to address survivors’ needs and provide trauma-informed care. The 21 counties of West Tennessee have only five certified SANE nurses, four of whom practice in Shelby County. But the Tennessee Bureau of Investigation received nearly 1,600 reports of sexual assault in West Tennessee in 2019, indicating a significant shortage of nurses certified to meet the need for this care.

Andrea Sebastian, DNP, PNP, SANE-P, an assistant professor in the UTHSC College of Nursing, has worked as a child abuse nurse practitioner for the last seven years at Le Bonheur Children’s Hospital and will serve as project manager of the SANE Training and Education through Partnerships for Underserved Populations (STEP UP) grant.

“During this time, I have recognized the importance of SANE nurses in our community. Currently, we do not have enough SANE nurses in West Tennessee to provide exams and resources to victims,” Dr. Sebastian said. “With this grant, we will be able to increase access to these invaluable resources and help victims of sexual assault in our community.”

The UTHSC team will work with West Tennessee Healthcare, the Shelby County Crime Victims and Rape Crisis Center, and the Whiteville Family Medical Clinic on the project. The team’s goal is to transform the nursing workforce by increasing the supply, distribution, and retention of certified SANEs and improving access to timely, expert care for all sexual assault survivors in West Tennessee.

Assistant Professor Christie Manasco, PhD, RN, is one of the co-investigators on the grant. “The funding from this grant will significantly help us close the gaps to equitable SANE care in West Tennessee. The efforts supported by these funds will help us to reduce inequalities and disparities and promote better outcomes for survivors,” she said.

Beginning in July, the STEP UP grant team will launch a plan to recruit up to 61 registered nurses or advanced practice registered nurses (APRNs) from the West Tennessee counties, with a focus on the rural and underserved areas. The grant will pay for participants to earn certifications through community or academic programs for adult and pediatric patients, known as SANE-A® and SANE-P®.

The grant team will also work with regional stakeholders to develop and implement a regional Sexual Assault Response and Resource Team (SARRT) that will assess the needs for sexual assault services in the area, reduce barriers to SANE training, and coordinate SANE clinical training opportunities. Grant funding also will be used to develop and provide resources for SANE self-care, peer mentoring, continuing education, and recertification.

Dr. Sebastian will be supported on this grant by co-investigators including Dr. Manasco, Assistant Professor Lisa Beasley, DNP, APRN, NP-C, RN; Assistant Professor Sally Humphrey, DNP, ARN, CPNP-PC; and Assistant Professor Diana Dedmon, DNP, FNP-BC, director of Clinical Affairs. College of Nursing Dean Wendy Likes, PhD, DNSc, APRN-Bc, FAANP, will serve as women’s health adviser on the grant, and the program coordinator for the Doctor of Nursing Practice DNP program, Trimika Bowdre, PhD, MPH, will be the evaluation adviser.

“The College of Nursing is very grateful for the funding to support this important work of providing appropriate care to this very vulnerable group of people,” Dr. Likes said. “The need for this in West Tennessee is beyond question. I personally look forward to working with this team in the College of Nursing and our community partners to provide this vital service to our communities.”

Pioneering chemistry approach could lead to more robust soft electronics

Published

RESEARCH TRIANGLE PARK, N.C. — A new approach to studying conjugated polymers made it possible for an Army-funded research team to measure, for the first time, the individual molecules’ mechanical and kinetic properties during polymerization reaction. The insights gained could lead to more flexible and robust soft electronic materials, such as health monitors and soft robotics.

Conjugated polymers are essentially clusters of molecules strung along a backbone that can conduct electrons and absorb light. This makes them a perfect fit for creating soft optoelectronics, such as wearable electronic devices; however, as flexible as they are, these polymers are difficult to study in bulk because they aggregate and fall out from solution.

“Conjugated polymers are a fascinating class of materials due to their inherent optical and electronic properties which are dictated by their polymer structure,” said Dr. Dawanne Poree, program manager, U.S. Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory. “These materials are highly relevant to a number of applications of interest to Army and DoD including portable electronics, wearable devices, sensors, and optical communication systems. To date, unfortunately, it has been difficult to develop conjugated polymers for targeted applications due to a lack of viable tools to study and correlate their structure-property relationships.”

With Army funding, researchers at Cornell University employed an approach they pioneered on other synthetic polymers, called magnetic tweezers, that allowed them to stretch and twist individual molecules of the conjugated polymer polyacetylene. The research was published in the journal Chem.

“Through the use of novel single-molecule manipulation and imaging approaches, this work provided the first observations of single-chain behaviors in conjugated polymers which lays the foundation for the rational design and processing of these materials to enable widespread application,” Poree said.

Previous efforts to address the solubility of conjugated polymers have often relied upon chemical derivatization, in which the structures are modified with functional groups of atoms. However, that approach can affect the polymer’s innate properties.

“The conjugated polymer is really a prototype,” said Dr. Peng Chen, the Peter J.W. Debye professor of chemistry and chemical biology at Cornell. “You always modify it to tailor it for applications. We are hoping everything we measured – the fundamental properties of synthesis kinetics, the mechanical property – become benchmark numbers for people to think about other polymers of the same category.”

In 2017, Chen’s group was the first to use the magnetic tweezers measurement technique to study living polymerization, visualizing it at the single-molecule level. The technique had already been used in the biophysics field for studying DNA and proteins, but no one had successfully extended it to the realm of synthetic polymers.

The process works by affixing one end of a polymer strand to a glass coverslip and the other end to a tiny magnetic particle. The researchers then use a magnetic field to manipulate the conjugated polymer, stretching or twisting it, and measuring the response of a single polymer chain that grows.

The amounts are so small, they stay soluble in solution, the way bulk amounts normally would not.

The team measured how long chains of conjugated polymers, which consist of hundreds of thousands of monomer units, grow in real time. They discovered these polymers add a new monomer per second, a much faster growth than their nonconjugated analogs.

“We found that while growing in real time, this polymer forms conformational entanglements,” Chen said. “All polymers we have studied form conformational entanglements, but for this conjugated polymer this conformational entanglement is looser, allowing it to grow faster.”

By pulling and stretching individual conjugated polymers, so-called force extension measurements, the researchers were able to assess their rigidity and better understand how they can bend in different directions while remaining conjugated and retaining electron conductivity.

They also discovered the polymers displayed diverse mechanical behaviors from one individual chain to the next-behaviors that had been predicted by theory but never observed experimentally.

The findings highlight both the uniqueness of conjugated polymers for a range of applications as well as the strength of using a single-molecule manipulation and imaging technique on synthetic materials.

“Now we have a new way to study how these conjugated polymers are made chemically and what is the fundamental mechanical property of this type of material,” Chen said. “We can study how these fundamental properties change when you start tailoring them for application purposes. Maybe you can make it more mechanically flexible and make the polymer longer, or adjust the synthesis condition to either synthesize the polymer in a faster or slower way.”
