Vandal Science News - September 2020

Dear Friends of the College of Science, 

Welcome to fall semester. U of I students are back, although campus looks and feels different this semester. Students are masked; faculty are teaching in masks or face shields; and fewer students are in our classes each time they meet. We’ve even co-opted the Pitman Center ballrooms for some larger enrollment classes to provide adequate social distancing.

College of Science department chairs and faculty worked overtime this summer to prepare for fall semester instruction. It was a difficult landscape to navigate since information on COVID-19 and best practices changed frequently. Faculty in the college banded together to share strategies for teaching online or in a HyFlex mode (meaning some students are in the classroom while others are interacting online). Getting ready for the semester was a heavy lift and I am immensely grateful to all our department chairs, faculty and staff for pulling everything together. We are ready to deliver another great semester in the college and provide our students the education they want and deserve!

For more details on the university’s fall semester plans and communications from President Green, please visit the university’s COVID-19 webpage.

Beyond face masks and social distancing, the college also has a different look. As you may have noticed, some of our departments had been working as teams over the past several years on academic and research initiatives, often sharing staff efforts, and sometimes sharing a department chair. As part of our annual program prioritization process, the State Board of Education approved several department mergers. We’re excited to have Professor Hirotachi Abo serving as chair of the newly formed Department of Mathematics and Statistical Science. We’re currently working on the selection process for the chair of the new Department of Geography and Geological Sciences. The new departments will continue to offer all degree and certificate options that the individual units offered, and our students will continue to have access to the courses they need. Through these consolidations, the units will maximize the benefits of interdisciplinary collaboration and innovation in both research and teaching. We will share additional information on these mergers in follow-up communications.

College of Science success in research continues to grow. Science faculty were incredibly successful this summer in bringing in new grants and publishing their research. College COVID-19 research efforts continue to expand as Ben Ridenhour (Mathematics and Statistical Science) spearheads efforts to model coronavirus infections for the state of Idaho. Faculty in Biological Sciences are working on coronavirus treatment strategies, and one of those groups is highlighted in this month’s features. We also highlight Ashley Farre (Ph.D. student in Biological Sciences), who received a prestigious graduate fellowship from the National Institutes of Health.

While the university faces many challenges this year due to the pandemic, I remain optimistic that the college and university will emerge stronger than ever. Our faculty are creative and hardworking, and our students are here because they want the in-person college experience that includes regular interactions with faculty, staff and peers. It is our land grant mission to serve and educate the people of Idaho, and we will continue to do so by innovating and looking forward.

Go Vandals!

Publications

  • Tim Bartholomaus (Assistant Professor, Department of Geography and Geological Sciences) co-authored a paper In Polar Biology entitled “Rolling stones gather moss: movement and longevity of moss balls on an Alaskan glacier,” that attracted national attention and was featured on National Public Radio.
  • Jeff Hicke (Professor, Department of Geography and Geological Sciences) co-authored a paper in Forest Ecology and Management entitled “Characterizing Recent Bark Beetle-caused Tree Mortality in the Western United States from Aerial Surveys.”
  • Sebastian Stoian (Assistant Professor, Department of Chemistry) recently published four articles with members of his research group. The first is in Dalton Transactions. The second paper was published in Chemical Communications and describes a new molecule that changes its color and its magnetic properties in solution as a function of temperature. These molecules have the potential to function as sensors and as molecular switches.
  • Alex Roseborough (B.S. Chemistry 2020), a former undergraduate researcher in the Stoian lab (Department of Chemistry), published a first-author paper with Dr. Stoian in Polyhedron . Alex recently joined the chemistry Ph.D. program at Oregon State University. Alex also is a co-author on the fourth paper from the Stoian lab that was published recently in Inorg. Chem.
  • Matthew Hedman (Associate Professor, Department of Physics) co-authored a paper in The Astronomical Society of the Pacific entitled “Forecasting Rates of Volcanic Activity on Terrestrial Exoplanets and Implications for Cryovolcanic Activity on Extrasolar Ocean Worlds.”
  • Tristan Amaral (M.S. Geology 2019) and Tim Bartholomaus (Assistant Professor, Department of Geography and Geological Sciences), published an article in JGR Earth Surface in which they tested six methods to predict iceberg calving on 50 of Greenland’s glaciers that terminate in the sea. To reduce uncertainty in coastal flooding during the coming years, they identified the best way to include iceberg calving in simulations of future glacier and ice sheet loss.
  • Grant Harley (Assistant Professor, Department of Geography and Geological Sciences) uses tree rings to reconstruct past climates. One study of the Oregon/Washington Blue Mountains found wildfires burned entire landscapes — even riparian zones — during droughts over the past 400 years. A second study of the Oregon/Washington Cascades found the local 2014-16 “snow drought” was unique over the past 500 years and declines in snowpack since about 1970 were most likely attributed to increased air temperatures linked to human-caused climate change.
  • An international team of conservation geneticists including Paul Hohenlohe (Associate Professor, Biological Sciences) and Fish and Wildlife Sciences’s Lisette Waits recently published in Biological Conservation. They suggest three targets to help preserve the genetic component of biological diversity under the international Convention on Biological Diversity. Genetic diversity, which is decreasing, allows for adaptation, ensures species resilience under climate change and contributes to supporting human society and the life support systems of the biosphere.
  • Scott Nuismer and Jim Bull (Professors, Department of Biological Sciences) want to use “self-disseminating” vaccines to suppress viruses that jump from animals to humans. With self-disseminating vaccines, a small portion of the population can be inoculated with the vaccine, which will then pass from host to host. In Nature Ecology and Evolution, the researchers lay out a road map for overcoming the challenges for using these vaccines including identifying high-risk emerging pathogens, vaccine design and minimizing the risk of unintended consequences.
  • Undergraduate researchers Lance Fredericks and Cooper Roslund working with Paul Rowley (Assistant Professor, Department of Biological Sciences), Mark Lee and Angela Crabtree (research technicians in Biological Science) recently co-authored a paper in PLoS One entitled “The design and implementation of restraint devices for the injection of pathogenic microorganisms into Galleria mellonella.

Puzzler

Suppose I start writing the numbers from 1 on up one after another, as follows:

12345678910111213141516171819202122232425262728293031323334...

If I had an infinite amount of time and patience (I in fact have neither!) I could keep this string of digits going forever.

There are two parts to this month's puzzle:

  1. What is the two-millionth digit in this string of numbers?

  2. What six-digit number am I writing when I write the two-millionth digit?

Solution to May 2020 puzzler:

This was a pretty tough one -- it's tempting to get into all kinds of messy calculations. The way to keep things simple is to choose the right variables. Let's let PN, and D be the number of pennies, nickels, or dimes that Tom has over and above the numbers that Rachel has. (Then, since Tom has more of each of these kinds of coins, we know that PN, and D must all be positive integers.) Since Rachel has 4 more quarters, but Tom has 32 more coins total, we must have

P + N + D = 36 .

But also, since they each have the same amount of money, the value of Tom's extra coins must be the same as Rachel's extra 4 quarters. In other words:

P + 5N + 10D = 100 .

A little experimentation shows that the only two solutions to these two equations are

P = 20, N = 16, D = 0

and

P = 25, N = 7, D = 4

The first one, however, is not allowable, since D must be positive. (Tom has more dimes!) So, the second solution must be the right one, so Tom has 7 more nickels. Since Rachel has 23 nickels, Tom must have 30 nickels.

Correct Solvers:

1st correct solution: Alex Blumenfeld, NMR Lab Manager, U of I Chemistry

2nd correct solution: Alice Buerkle, B.S. Botany 1987

Others:

  • Greg Stenback, B.S. Geological Engineering 1985, M.S. Statistics 1987
  • Marianne Milander, Student (Animal and Veterinary Science, Microbiology)
