In the News: Biodiversity in Beer and Nut-cracking Monkeys
A powerful DNA tool holds the answers to crop population genetic variations, and archaeologists discover tools that monkeys used to get their nut fix. That and more in our science news roundup.
- As we shared last week in our video, high-throughput sequencing is a powerful tool available to scientists. This team used it to identify small genetic differences in plant crop populations: Exploring Genetic Diversity in Plants Using High-Throughput Sequencing Techniques, Current Genomics (August 2016)
- We've talked about beer made with wild yeast - here's an assessment of how many barley varieties are actually utilized by the industry. You know the number is low when there is a brewery putting Genebank accession numbers on its labels: The biodiversity of beer, Agricultural Biodiversity Weblog (5 July 2016)
- Ocean ice and sediment cores reveal a new connection between ocean circulation and climate patterns during the last ice age: Ocean circulation implicated in past abrupt climate changes, Science Daily (30 June 2016)
- Humans aren’t the only ones with a history of using tools. Primate archaeologists have found evidence of 700-year-old tools used by capuchin monkeys to crack open nuts: Monkeys used stone tools 700 years ago, BBC News (12 July 2016)
- If you study cancer, you probably were excited to hear about a new initiative to double the world’s number of cancer cell lines available to researchers (to 1,000!): Global Initiative Seeks 1,000 New Cancer Models, Scientific American (11 July 2016)

The Greatest Hits

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.

The Dawn of Birds

Around 65 million years ago, one of the largest mass extinction events in Earth’s history occurred. An estimated 75 percent of all species went extinct, from non-avian dinosaurs to types of mollusks, plankton, insects, and plants. With extinction, however, came the chance for animals like birds to diversify and expand into empty ecological niches in a process called adaptive radiation. Although the Cretaceous-Paleogene extinction event (K-Pg) may have enabled the rapid evolution of new species of birds, research published last Friday in the journal Science Advances suggests that birds have a much longer and more complicated history than previously thought.

Bones of Coral Reefs

In the middle of the Pacific Ocean, just off the small island of Kiritimati, corals are dying off at an astonishing rate. The small atoll, also called Christmas Island, suffers from high water temperatures caused by the current El Niño that have reached 4℃ above normal. Although these temperatures might be nice for a beachgoer, they do not bode well for the survival of the atoll’s extensive coral reefs.

Change in the Delta

After years of working at the Northwest Fishery Science Center as a project manager, focusing her work on salmon, Carmella Vizza felt she needed a change.
“I decided it was time for me to go back to grad school to be more involved in conducting my own research,” Vizza said.

The Edge of Extinction

With only 26 to 28 individuals left in the forests of southwest China, Hainan gibbons are the rarest primates on Earth. Habitat destruction and poaching have placed this species (Nomascus hainanus) on the cusp of extinction. Ongoing conservation efforts work to protect China’s endangered biodiversity, but tracking species decline is especially difficult. Extinction often occurs over centuries, and the extent of how humans affect animals is difficult to determine without a baseline of past population numbers. A recent study published in the Proceedings of the Royal Society B examined a novel resource in the fight to protect biodiversity and shed light on the decline of gibbon populations over time.
