patchRelative Growth Rates Documented by UC Davis Scientists for Project MERCCURI

“Encouraging” for Long-Term Manned Spaceflight

Do microbes grow differently on the International Space Station than they do on Earth? Results from the growth of microbes collected by SciStarter’s community of citizen scientists in Project MERCCURI indicate that most behave similarly in both places.

“While this data is extremely preliminary, it is potentially encouraging for long-term manned spaceflight,” said Dr. David Coil, Project Scientist in the Microbiology Lab of Jonathan Eisen at the University of California at Davis. “With this part of Project MERCCURI we hoped to shed light on how microbes associated with the normal, human and built environment behaved in space. Our focus was not on microbes that cause disease, but the many beneficial and neutral microbes that surround us on a daily basis.”

SciStarter and the Science Cheerleaders organized a community of thousands of people across the country to participate in the citizen science portion of the project, gathering samples from built environments such as chairs, doors, railings… even the Liberty Bell. Then the “microbiology team” in the laboratory at UC Davis grew up and examined hundreds of microbes. The team selected 48 microbes, which, with approval from NASA, rode the SpaceX Falcon 9 to the Space Station for further research. Of those 48, only a handful grew at all differently in Space, and the difference was significant for only one: Bacillus safensis. This microbe was collected on a Mars Exploration Rover (before it was launched) at the NASA Jet Propulsion Laboratory in Southern California. It grew significantly better on the Space Station.

“We observed that the vast majority of the microbes we examined behaved the same on the Space Station as they do on Earth. In the few cases where we observed a microbe behaving differently in space than on Earth, we’d love to follow that up with further experiments,” said Dr. Coil.

In addition to comparing growth rates on Earth and the Space Station, UC Davis identified winners in three different categories for the “Microbial Playoffs” in space.

Best Huddle: the microbe that grew to the highest density, packing cells into the space allowed

  • Yuri’s Night, Los Angeles: Kocuria rhizophila was collected on a camera at a Yuri’s Night Party with Buzz Aldrin (the second person to walk on the moon).
  • San Antonio Spurs: Kocuria kristinae was collected on the court after a San Antonio Spurs game.
  • Discover Magazine: Micrococcus yunnanensis, collected from a dictionary at the offices of Discover Magazine.

Best Tipoff: the microbial competitor that took off growing like crazy from the start

  • Pop Warner Chittenango: Bacillus pumilus was collected on a Porta-Potty handle by Pop Warner Chittenango Bears cheerleaders.
  • Smithsonian Air & Space Museum: Pantoea eucrina was collected on the Mercury Orbitor at the Smithsonian Museum of Air and Space.
  • Pop Warner Saints: Bacillus horikoshii was collected on a football field by Pop Warner Saints cheerleaders from Port Reading, NJ.

Best Sprint: the microbe that grew the fastest during the sprinting portion of growth (technically known as the “exponential growth phase”)

  • Oakland Raiders: Bacillus aryabhatti was collected on a practice football field used by the Oakland Raiders.
  • Pop Warner Chittenango: Bacillus pumilus was collected on a Porta-Potty handle by Pop Warner Chittenango Bears cheerleaders.
  • Mars Exploration Rover (JPL): Paenibacillus elgii, collected from a Mars Exploration Rover before launch (2004) at the Jet Propulsion Laboratory (JPL- NASA, Pasadena, CA).

Find rankings of all 48 samples in these three growth categories on the Results page at the Space Microbes web site.

Other elements of Project MERCCURI are still in process. In addition to overseeing the microbial playoffs, astronauts also collected microbes on the Space Station and sent those back to Earth. The UC Davis team has analyzed the data from those and are preparing a scientific publication on the results. In addition, members of the public contributed 3,000 cell phone and shoe samples for an ongoing analysis of which microbes live where, and how that compares to the ISS.

“With this project, thousands of people contributed to research on the Space Station and at UC Davis, one of the leading microbiology research labs in the country,” said Darlene Cavalier, Founder of SciStarter and Science Cheerleader, which led the microbe collection effort. “Our goal is to spur even more people to get involved in significant science. Whether someone is a child or an adult, is interested in space or the ocean, in biology or chemistry, in the climate or computers – scientists are working on research and development that would benefit from more participation.” Learn about and sign up to help with more research projects at www.SciStarter.com .

Project MERCCURI is coordinated by Science Cheerleader (current and former NFL and NBA cheerleaders pursuing science and technology careers), SciStarter, and UC Davis, in conjunction with the Argonne National Laboratory. The Project is made possible by Space Florida, NanoRacks, and the Alfred P. Sloan Foundation.

Pollinating animals play a crucial role in our food production system, and they are essential in maintaining the health and vitality of many ecosystems.  Unfortunately, many pollinator species, such as bees and butterflies, have been declining recently.  In response to that decline, the national Pollinator Health Task Force, commissioned by the White House, recently released the Pollinator Health Strategy.

This is a guest post by Michael Bear Citizen Science Project Director at Ocean Sanctuaries.  In this post, he describes a citizen science led effort to catalog marine life living in and around the HMCS Yukon. In 2000, the Yukon was transformed into an artificial reef as part of San Diego’s  marine conservation effort.

 

In 2000, the City of San Diego in collaboration with the San Diego Oceans Foundation (SDOF), purchased, cleaned and sank a 366 foot-long Canadian warship called the HMCS Yukon to create an artificial reef, a task at which has been spectacularly successful. Sitting at the bottom of the San Diego coast, the Yukon attracts dozens of local marine life species and is becoming a revenue-generating attraction for tourist divers from around the world.

When this project started, both the SDOF and the local scientific community were curious to understand the effects of an artificial reef on local fish populations and surrounding marine life. A joint study was undertaken by SDOF and Dr. Ed Parnell of Scripps Institution of Oceanography and released in 2004.¹ Crucial to the study was data gathered by local citizen science divers to generate a baseline of marine life species on the ship.

This year, Ocean Sanctuaries, San Diego’s first citizen science oriented, ocean non-profit is conducting a follow up study to the pioneering work of Dr. Parnell and colleagues. Established in 2014, Ocean Sanctuaries encourages and supports citizen science projects which empower local divers to gather marine data under scientific mentorship and forward our understanding of the oceans. Ocean Sanctuaries currently has three active citizen science projects. ‘Sharks of California’ and the ‘Sevengill Shark ID Project’ are both shark related. The third project is the follow-up study on the Yukon called the Yukon Marine Life Survey.

The data gathered in this project will be mainly photographic. Local divers will photograph specific areas of the ship in quadrats and with transect lines and the data will to be compared with the same areas examined in the 2004 study.

The project plans to use a web-based application for wildlife data management called ‘Wildbook’ for cataloging observations made in the Yukon Marine Life Survey. ‘Wildbook’ was originally designed to identify whale sharks, but will be modified as a multi-species database for use with the Yukon Marine Life Survey.²

Referring to the original Yukon Marine Life Survey of 2004¹, Barbara Lloyd, Founder of Ocean Sanctuaries says, “The Yukon Artificial Reef Monitoring Project (ARMP) was a short-term baseline study of fish transects and photo quadrats. The ARMP project has been gathering data for about a decade now.  We at Ocean Sanctuaries strongly believe that a follow up study to the original baseline study can provide the research and fishing communities with valuable marine life data.  In addition, unlike the original study, we intend to use photographs to ensure verifiable encounter data.  We aim to create a large base of citizen scientists to take the photos and enter the data.  This crowd-sourced data will allow us to collaborate between citizens and researchers.”

The current Yukon Marine Life Survey will span at least five years. Once completed, the data will inform scientists of changes to the marine life on the ship enabling California coastal managers to evaluate the impact of artificial reefs on local marine species.  Take a video tour of the Yukon and learn more about the project at SciStarter.
