Sending MicRobes to Space Could Improve Astronaut Health
April 01, 2025
Though most of us will never step foot onto a spaceship, space travel has had a deep impact on human life and society, particularly when it comes to health and medicine.
Because low-gravity conditions cause dramatic changes in our cells and tissues, space exploration allows scientists to conduct biomedical experiments that are impossible on Earth, which has enabled the discovery of new drugs, inspired the development of new medical devices, and helped us better understand aging and other biological processes.
However, these experiments require astronauts to run them, and the human body is not designed to live on a space station. Astronauts often experience a variety of health pRoblems while in space, including immune dysfunction, skin rashes and other inflammatory conditions.
If not properly managed, these types of health issues can result in more human error and reduced length of space missions, ultimately reducing the quantity and quality of the experiments on board and slowing the pace of scientific progress.
Now, research from UC San Diego has helped shed light on what causes health issues in astronauts and what could be done to make them healthier.
The findings, published in the journal Cell, could help empower the next generation of space-based research and also have implications for the health and safety of people in sterile environments here on Earth.
The researchers collaborated with astronauts who swabbed 803 different surfaces on the International Space Station (ISS)-around 100 times more samples than have been taken in previous surveys.
Back on Earth, the researchers identified which bacterial species and chemicals were present in each sample. Then, they created three-dimensional maps illustrating where each was found on the ISS and how the bacteria and chemicals might be interacting.
"It's possible the extremely sterile environment of the ISS may not be healthy in the long term for astronauts, who could benefit from interactions with more Earth-like micRobes while in space," said co-corresponding author Pieter Dorrestein, Ph.D., a professor in the Skaggs School of Pharmacy and Pharmaceutical Sciences at UC San Diego and a 2024 Highly Cited Researcher.
"In addition to the ISS, there are many other places on Earth where micRobe levels are kept low for extended periods of time, such as hospitals or submarines, where we may need to diversify the micRobial environment."
When they compared the ISS to different human-built environments on Earth, the researchers found that the ISS micRobial communities were less diverse than most of the samples from Earth.
The ISS samples were more similar to samples from industrialized, isolated environments, such as hospitals and closed habitats, and homes in urbanized areas.
Compared to most of the Earth samples, the ISS surfaces were lacking in free-living environmental micRobes that are usually found in soil and water. Most of the micRobes they found on ISS were associated with human skin.
Because exposure to a wide variety of bacteria in various settings can help boost the immune system, the researchers hypothesize that astronauts may develop inflammatory conditions because their immune system is insufficiently challenged in space.
However, this also suggests that astronauts' health could benefit from intentionally introducing more micRobial diversity to the space station.
The researchers compare this suggestion to the well-studied beneficial impacts of gardening on the immune system.
"There's a big difference between exposure to healthy soil from gardening versus stewing in our own filth, which is kind of what happens if we're in a strictly enclosed environment with no ongoing input of those healthy sources of micRobes from the outside," says co-corresponding author Rob Knight, Ph.D., who was recently named the 2025 Scientist of the Year by the Achievement Rewards for College Students (ARCS) Foundation San Diego chapter and is also a 2024 Highly Cited Researcher.
In the future, the researchers hope to refine their analyses to be able to detect potentially pathogenic micRobes and signals of human health from environmental metabolites.
They say that these methods could also help improve the health of people living and working in similarly sterile environments on Earth, such as hospitals or submarines.

Scientists shovel dirt in book for parents
http://seattlesciencewriter.com/blog/scientists-shovel-dirt-in-book-for-parents/
Should you wash the pacifier, if it falls on the ground, or should you lick it off and give it back to your child?
Two scientists tackle this - and hundreds of other questions about dirty and clean in the new book, "Dirt is Good: The Advantage of Germs for Your Child's Developing Immune System." Hint - They fall on the side of licking and returning the pacifier, with qualifications.
Both Jack Gilbert and Rob Knight are parents. They've been sleepless in the nursery, and worried about vaginal versus c-section births. They've framed the science as a series of parent questions from pregnancy and childbirth itself all the way up the playground years. Science nitpickers will find plenty of details about what is called the micRobiome - the ecology of all the microscopic creatures who share our skin and our guts. (And our hair, and our armpits, and ...)
Gilbert is a PhD and professor of surgery and director of the MicRobiome Center at the University of Chicago. Knight is a PhD and professor of pediatrics and computer science at the University of California, San Diego. Gilbert and Knight are not medical doctors, and don't give medical advice. Their co-writer, Sandra Blakeslee, wrote for the New York Times for many years.
These three bring academic heft to their answers, often quoting specific research projects that have established certain science principles. There are more than 180 references in the book's appendix.

Wants to track (you), but does not wish to be tracked himself.
Anons meet Gary Shekhter. Up out of Washington D.C. Dulles Airport we have tail number N830GS. 2009 GULFSTREAM AEROSPACE GV-SP (G550). That's a twenty seater. Currently cruising at the astounding aerial performance altitude of 48,000 feet just north of Santa Fe, NM. And presumably headed back to his home base of San Diego.

$350K Gift to UCSD to Create COVID-19 Epidemiological Tracking Study
"Our economy is struggling, so the sooner people can get back to their jobs, the better for our region," said UC San Diego Chancellor Pradeep K. Khosla
By City News Service - Published June 5, 2020
UC San Diego announced a $350,000 donation from Jean and Gary Shekhter, which will help fund San Diego Epidemiology and Research for COVID-19 Health, a collaborative research study aimed at helping local businesses and employees return to work safely by screening community members for presence of the coronavirus.
The research study is co-led by UC San Diego, Scripps Research and
Rady Children's Hospital-San Diego.
"Nearly 300,000 San Diego County residents have lost jobs because of
COVID-19," said UC San Diego Chancellor Pradeep K. Khosla. "Our economy is struggling, so the sooner people can get back to their jobs, the better for our
region."
UC San Diego launched a similar testing program on campus in March called Return to Learn. The evidence-based program aims to make monthly COVID-19 testing available to students to track the novel coronavirus and better position the university to resume in-person activities in fall 2020.
"Based on my understanding about COVID-19, the most efficient way of opening the economy is to screen more people," said Gary Shekhter. "Screening gives us an understanding of what's going on in the community such as seeing a particular situation in an area ignite, then isolating and dealing with the contact area."
Other research partners include the Sanford Consortium for Regenerative Medicine, Salk Institute for Biological Studies and Biocom. At UC San Diego, SEARCH is led by researchers Gene Yeo, Rob Knight and Louise Laurent.
"I hope our gift will inspire others. We want to encourage the community to get involved in the COVID-19 crisis," Jean Shekhter said. "Because of UC San Diego, our region has developed a tremendous base for life sciences. We feel it is very important to support this great institution."
