Loitering in the Atmosphere: Wildfire Aerosols Linger Longer Than Expected

Light-absorbing brown carbon aerosols emitted by wildfires remain longer in the atmosphere than expected, which could have implications for climate predictions.

Rising 2,225 meters (7,300 ft.) into the air on an island in the Azores archipelago, Pico Mountain Observatory is an ideal place to study aerosols—particles or liquids suspended in gases—that have traveled great distances in the troposphere.

The troposphere is the portion of the atmosphere from the ground to about 10 kilometers in the air. Nearly all of the atmosphere’s water vapor and aerosol exist in the troposphere, and this is also where weather occurs. The Pico Observatory rises above the first layer of clouds in the troposphere, known as the atmospheric marine boundary layer. At that boundary the temperature drops rapidly, and relatively high humidity decreases as cooling air forces water to condense into cloud droplets.

October is ADHD Awareness Month

Attention-Deficit/Hyperactivity Disorder (ADHD) affects children, adolescents and adults in the United States. The mission of ADHD Awareness Month is to educate the public by disseminating reliable information based on the evidence of science and peer-reviewed research.

Did you know?

  • Millions of people in the United States are affected by ADHD
  • Nearly 9 percent of children ages 3-17 have been diagnosed with ADHD
  • About 4.5 percent of adults have been diagnosed with the disorder

ADHD is one of the most prevalent and misunderstood conditions in the world. Its core symptoms include problems with attention, impulsivity and hyperactivity.

This year’s theme is “Setting the Record Straight.” Armed with recent information about ADHD and research-supported practices, life can be better for those with ADHD.

Consider these facts—individuals with ADHD:

  • Experience more challenges in school, at work and in social relationships
  • Have higher rates of emergency room visits and automobile accidents and are at greater risk for substance abuse

ADHD is a neurodevelopmental disorder that affects millions of Americans regardless of age, gender, ethnicity or socioeconomic status. Recognized widely by medical organizations as varied as the National Institutes of Health (NIH), the Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP), ADHD causes significant impairment throughout the daily lives of those affected by it. The good news is that when children, teens and adults are diagnosed and receive treatment, they can lead fulfilling lives.

Visit the ADHD Awareness Month coalition’s website to learn more about this real and serious health condition. The website has a wealth of information to help affected individuals and their families cope with the daily challenges of life.

Drosophilids of the Midwest and Northeast – Reception for the Publication of a New Open Access Book

When John Jaenike (University of Rochester) visited Thomas Werner (Bio Sci) as part of a faculty-mentoring grant, the seed was planted for a unique species identification guide. This has now grown into "Drosophilids of the Midwest and Northeast" hosted at Michigan Tech and published as an open educational resource on Digital Commons at Michigan Tech.

Werner became interested in the question “What is life?” as a four-year-old child in his parent’s garden in what was then East Germany. Jaenike has been interested in all aspects of natural history for as long as he can remember. In 2012, Jaenike visited Michigan Tech to give a talk on fruit fly parasitism and on an adventure collecting local drosophilids from mushroom traps, Werner, amazed at the breadth of Jaenike's knowledge, asked Jaenike to teach him everything he knew about wild fruit flies. And so was born the idea to develop this book.

Join the authors, at a reception celebrating the launch of their book on Digital Commons at Michigan Tech, and the upcoming release of version two, from 10 to 11:30 a.m. Wednesday, Oct. 10 in the East Reading Room of the library. Light refreshments will be served.

Today is #AskAnArchivist Day

Today, archivists around the country will take to Twitter to respond to questions tweeted with the hashtag #AskAnArchivist.

Free WW1CC Film Screening Tomorrow

The Modern Languages Program will host a screening of the François Ozon’s 2016 film "Frantz" at 7 p.m. tomorrow (Oct. 4) in Walker 134. The screening is free and open to the public.

Film synopsis: In 1919 Quedlinburg, Germany, a young woman named Anna is still mourning the death of her fiance, Frantz Hoffmeister, in the Great War while living with his devastated parents. One day, a mysterious Frenchman, Adrien Rivoire, comes to town both to pay his respects to Frantz's grave and to contact that soldier's parents. Adrian explains that he knew Frantz and gradually he wins Anna and the Hoffmeisters' hearts as he tries to connect with them. But the truth of his motives unveils no easy answers to their complex personal conflicts with each other and the dead man linking them (from IMDB pro).

The screening is part of World War I in the Copper Country (WW1CC), an extensive program of events and exhibits commemorating the WWI Armistice. Partners include Michigan Technological University, the Carnegie Museum of the Keweenaw and Finlandia University. WW1CC is made possible in part by a grant from the Michigan Humanities Council, an affiliate of the National Endowment for the Humanities.

Two Lectures by Renowned Crystallographer

World-renowned crystallographer Luca Bindi from the University of Florence will present two lectures during the week of Oct. 7. The first is a general lecture open to everyone that recounts the remarkable story of the discovery of natural quasicrystals, "Impossible Crystals Fallen from the Sky." This talk will take place at 4 p.m. Oct. 9 in M&M building, room U115. His second talk will be a more technical research seminar titled, "From the Invalidity of the Law of Rational Indices to the Concept of Superspace: A Crystallographic Excursion in the Modulated World of Minerals," which will take place at 1 p.m. Oct.11 in Fisher 138.

Bindi earned his PhD in Mineralogy and Petrology from the University of Florence and Perugia. In 2014 he earned habilitation and the rank of full professor of Mineralogy and Crystallography, also at the University of Florence, where he continues to teach and conduct research, particularly in the area of complex crystal structures. From 2006 to 2011 he also served as Main Curator of the Division of Mineralogy of the Natural History Museum of the University of Florence (NHMUF). The mineral lucabindiite was named in his honor in 2011. Among his numerous prizes and awards is the 2018 the Aspen Prize, which was awarded to Bindi and colleague Paul Steinhardt for the discovery of natural quasicrystals.

Bindi's visit is sponsored by the Department of Chemistry, the Department of Geological and Mining Engineering and Sciences, the Department of Materials Science and Engineering, the Earth, Planetary and Space Sciences Institute (EPSSI), the A. E. Seaman Mineral Museum and the Department of Physics.

Biological Sciences Seminar - Jacob Jaszczak and Rebecca Garrett Jaszczak

Biological Sciences presents double seminar speakers from 3 to 4 p.m. tomorrow (Oct. 4) in EERC 229.

Jacob Jaszczak is a postdoctoral scholar, Howard Hughes Medical Institute, University of California, San Francisco. He will present "Behavior in the periphery: development of a sensory switch in the Drosophila peripheral nervous system."

Dysfunction of the peripheral nervous system (PNS) profoundly impacts conditions across diverse life stages, such as the tactile-sensitivity of autism spectrum disorders in children (Orefice et al., 2016) or the hot-flashes during perimenopause in adults (Archer et al., 2011).

Rebecca Garrett Jaszczak, PhD candidate, biomedical science graduate program, University of California, San Francisco. She will present "Heterogeneity among migrating primordial germ cells revealed by single cell RNA sequencing."

Primordial germ cells (PGCs) are precursors to sperm and egg cells. Most mammalian PGCs are specified in the epiblast —far from their eventual tissue niche of the gonad—and must undergo an arduous migration to the forming embryonic gonads. However, not every PGC is a successful migrant. Previous studies indicate that mouse PGCs exhibit heterogeneous responses to migration cues, suggesting that observed variation in migration behavior of PGCs could arise intrinsically.

Teaching at Tech Luncheon Workshop - Faster Feedback: Escape the Grading Grind with Student Peer Review

Buried in grading? While students can’t grade each other, one possible way to reduce your grading load is to separate formative feedback from grading. When provided with the right resources, there’s evidence that students can provide excellent feedback and simultaneously deepen their own learning too.

This “peer review” technique isn’t just limited to papers and reports but can be used for homework of virtually all types. In this luncheon workshop from noon to 1 p.m. on Tuesday, Oct. 16, we’ll explore when peer review can work well, when it should be avoided, and how to optimize learning. Lunch will be available for those who register by Friday, Oct. 12.


Environmental Engineering Graduate Seminar

The next Environmental Engineering Graduate Seminar will be held at 3 p.m. Monday (Oct. 8) in GLRC 202. Carolyn Medin will present "Prevention and Mitigation of Hollow Fiber Membrane Fouling in Direct Contact Membrane Distillation Applications."

Medin received a bachelor’s degree in biology with a minor in environmental engineering from New Mexico Tech in 2016, and a master’s degree in environmental engineering from New Mexico Tech in 2018. She is currently pursuing a doctorate in environmental engineering from Michigan Tech.

Distinguished Ecologist Lecture Tomorrow

The next event in the Distinguished Ecologist Lecture Series will take place from 12:30 to 1:30 p.m. tomorrow (Oct. 4) in U.J. Noblet Forestry Building, room G002.

Janet Silbernagel will present "Landscape assessments and modeling for waterbird conservation in China." Silbernagel is a professor of landscape architecture, Department of Planning and Landscape Architecture at the University of Wisconsin-Madison. 

Those wishing to meet with Silbernagel during her two-day visit (Oct. 4-5) are asked to contact Audrey Mayer (SFRES).

ICC Distinguished Lecture Series

The next ICC Distinguished Lecture take place at 3 p.m. Friday (Oct. 5) in Dow 642. Chung-Kuan Cheng will present "The Life of SPICE as a Transient Circuit Simulator."

Simulation Program with Integrated Circuit Emphasis (SPICE) is one of the most successful academic products. The software package and its derivatives have become the bread and butter of circuit designers. After 47 years, the core of its transient simulation algorithms remains the dominant approach to produce the gold standard for the characterization of the circuit behavior. Cheng will discuss the history of the SPICE development, the theory, the efforts of various ingenious methods, the future directions and what he has learned from these endeavors. 

Cheng is now with the University of California-San Diego as a distinguished professor at the CSE Department and an adjunct professor at the ECE Department.

Chemistry Seminar

Paul Goetsch (Bio Sci) will present "Genomes to Genes to Proteins: Using CRISPR/Cas9 to illuminate how cells maintain identity," at 3 p.m. Friday (Oct. 5) in Chem Sci 101.

Goetsch's research focuses on assessing how the highly conserved DREAM transcriptional repressor complex maintains the germ vs. soma cell fate decision. Loss of the Caenorhabditis elegans DREAM complex results in misexpression of germline genes in somatic cells, a phenomenon called a “soma-to-germline transition” that is commonly observed in cancer cells. He has developed a functional genomics pipeline that integrates new CRISPR/Cas9 genome editing tools, high-throughput sequencing analysis, genetics, biochemistry and cell biology to elucidate the events that occur when somatic cells lose their identity.
