Editor’s Note: After two years of exciting and engaging work, staff writer Adele Crane will be leaving Scientific Collections International for graduate school in Arizona. Out of 214 posts garnering more than 34,500 views, Adele chose some of her favorite articles.

From a small natural history museum in Pennsylvania to a seed-bank built to survive doomsday scenarios, collections reside all around the world in many forms. My work over the past two years with Scientific Collections International (SciColl) has been to chip away at only a fraction of the specimens and samples out there, exploring a slew of topics from microbes in your backyard to moon rocks - and on rare cases, even both!

When we initially started the blog, we wanted to connect collections to disease research and response. Articles on cross-disciplinary and novel approaches to outbreaks would lead up to SciColl’s very first workshop on Emerging Infectious Diseases. The workshop was indeed timely, coinciding with the Ebola epidemic in Africa, and it highlighted the need to make this type of active outreach ongoing, instead of sporadic.

Perhaps as a preface to the type of work I will pursue in graduate school, my favorite articles were a fantastic education on how to bridge unique specimens with historic and current disease research. To break down the broad topic of “emerging infectious diseases,” we focused on smaller case studies of known and relatively unknown pathogens that affect millions around the world:

• Disease Collections and How They Can Save the World: In 1976, a broken vial of blood transported in luggage from the Democratic Republic of the Congo found its way to the young Belgian scientist, Peter Piot. The blood carried one of the most feared pathogens in current disease research. 

• C. Miguel Pinto, the Disease Detective: A conversation with C. Miguel Pinto in our very own museum explored the cross-section of disease research and classic taxonomy, in which basic evolutionary principles are tested.

Over the course of the blog, we looked beyond case studies and current research challenges. How can ancient specimens inform future problems? There are many examples where collections were used to further important research in areas like environmental change and food security.

When we take a step back, the larger impacts of educating the next generation of scientists or bringing countries together to protect biodiversity are extraordinarily important. After working with SciColl, I am grateful to have gained that perspective and I hope to hear many more of these stories in years to come:

• Microbes and Middle Schools: Citizen science has the ability to reach both students and researchers in powerful ways. Collections that not only support invasive species studies but engage middle schoolers in science are a cornerstone of ongoing work at the North Carolina Museum of Natural Sciences. 

• Seeds for the End of the World: Seed banks preserve both biological diversity and cultural heritage. Banks around the world, from Peru to Norway, are working to provide a future for agriculture and historical practices. 

• Smart Collecting: A New Collecting Culture: What began as a short discussion in our Emerging Infectious Disease workshop turned into a larger conversation about a “collecting culture” that could be improved for museums and biobanks alike.

Save the Date: Food Security Symposium

We are excited to announce the symposium “Stressors and Drivers of Food Security: Evidence from Scientific Collections,” which will bring together researchers and experts on scientific collections across disciplines to address issues regarding food security. This symposium will be held September 19 to 21 at the National Agriculture Library in Beltsville, Md., and will be hosted by the U.S. Department of Agriculture and Scientific Collections International.

A critically important source of funding for collections in the United States has been reinstated. Though the program is still under evaluation, this money will go towards the preservation of specimens and infrastructure. This week in the news, we read about this program, as well as research projects underway around the world that depend on collections to further understand human disease, migration, and agriculture.

Brave New World

In a laboratory, just outside downtown Portland, Mowgli Holmes and his team at Phylos Bioscience are embarking on a brave new world.

“We’re creating the first genetically defined collection that has ever been,” he said. “... We know less about it than any other crop.”

That crop Holmes is referring to is cannabis, and that collection he and his team of genetic researchers have been working on the past couple of years is an extensive genomic dataset. Holmes and his group will expand upon the "draft" genomics work previously done.

A Brief History Camels (And Humans)

For the past 3,000 years, single-humped camels, known as dromedaries (Camelus dromedarius), have provided an important source of food and transport to desert communities. The origin of the domesticated dromedary, however, remains relatively unknown. A recent article published in the journal Proceedings of the National Academy of Sciences, reveals some clues as to where and when humans started to depend upon these animals.

Seeds of Scientific Progress

Editor’s Note: Our Food Security Symposium has been postponed until September 2016. Please email us at scicoll@si.edu with any questions or join our mailing-list for routine updates on the new symposium. 

Around 1800, the world's population reached one billion people. In less than 50 years from today, that number is projected to reach 9.7 billion people. Although this rapid increase in population size can largely  be attributed to health, sanitation, and farming innovations in the 20th century, it has roots in the Industrial Revolution.

Millet’s Long History

Recent research suggests that common millet (Panicum miliaceum) - often used as birdseed today - may have bridged the gap between nomadic hunter-gatherer cultures and agrarian societies in Neolithic Eurasia, holding possible lessons for current food security challenges.

Wild Plants and the Future of Crops

According to a recent study in the journal Nature Plants, around 95 percent of wild relatives of agricultural crops are insufficiently safeguarded in gene banks around the world. These crop wild relatives (CWR) are closely related to domesticated plants and have become increasingly important in efforts to protect crops against threats like drought, pests, and disease.

Last week, 25 specimens of fungi collected by the famed botanist and inventor George Washington Carver were discovered in the Wisconsin State Herbarium at the University of Wisconsin-Madison. Born into slavery around 1864, Carver became one of the most prominent African-American scientists and is now well known for his research with peanuts, sweet potatoes, and soybeans.

Ice Cores and the Ancient Man

In 2003, paleoclimatologist William Ruddiman at the University of Virginia hypothesized that early humans significantly altered the climate by burning large areas of forests to clear land for farming and grazing. The greenhouse gases released into the atmosphere - mainly carbon dioxide and methane - halted a natural cooling cycle and possibly prevented another ice age.

In the News: The Blue Rose

Earlier this year, the International Center for Agricultural Research in the Dry Areas (ICARDA) made a request to withdraw seeds from the Svalbard Global Seed Vault, which holds more than 850,000 samples from every country in the world. This request is the first of its kind for the “Doomsday Vault” that holds duplicate seed samples for national and international gene banks. The Syrian civil war forced ICARDA to move its headquarters from Aleppo, Syria, to Beirut, Lebanon, in 2012, and researchers managed to save 80 percent of the seed samples by sending them into storage at Svalbard.

Although such a withdrawal will allow ICARDA to regenerate these precious samples, it reveals the vulnerability of collections to war or even natural disasters. The year of 2015 marked a specific effort by individuals and organizations around the world to protect and sustain scientific collections, from those housed in natural history museums to frozen specimens in gene banks. We identified major trends that have affected both how collections are viewed in science and policy, as well as how they can be protected for generations to come. Read to learn more about what happened in the collections world this year, and what you should watch out for in 2016.

With 158 articles published and more than a year underway, Collections in the News has sought to raise awareness about ongoing research done with scientific collections. This year brought visitors from 95 countries to our blog who read about a disease detective at the National Museum of Natural History, stopped for their Monday morning coffee break each week, and had the chance to learn how microbes and mammoth bones teach us more about our world.

Some blog highlights for 2015 include article series on international efforts that work to protect the planet’s soils and address climate change problems. We also participated in GIF week with Deep Sea News and celebrated Thanksgiving with maize scientists. Read more below about these article series!

In the News: Return to the Wild Crops

As families around the United States begin their Thanksgiving feast, they should be particularly grateful for the pumpkin. According to a study published last week in the journal Proceedings of the National Academy of Science, this beloved squash survived extinction only through domestication by humans thousands of years ago.

Ancient DNA and a History of Human Migration

Around 60,000 to 100,000 years ago, modern humans migrated out of Africa and proceeded to populate every corner of the world. Although ancient DNA analyses have added complexity to the routes of human migration, from Neolithic farmers to early hunter-gatherers in Europe, the birthplace of humanity has remained elusive. Among other challenges, regional hot temperatures that quickly degrade genetic material barred ancient African remains from such studies. However, in research published last week in the journal Science, a skeleton found in a remote cave in Ethiopia produced Africa’s first ancient human genome.
