Each month, we highlight a different research topic on the International Space Station. In August, our focus is biological research. Learning how spaceflight affects living organisms will help us understand potential health risks related to humans on long duration missions, including our journey to Mars.
Cells, microbes, animals and plants are affected by microgravity, and studying the processes involved in adaptation to spaceflight increases our fundamental understanding of biological processes on Earth. Results on Earth from biological research in space include the development of new medications, improved agriculture, advancements in tissue engineering and regeneration, and more.
Take a look at a few of the biological research experiments performed on space station:
Biomolecule Sequencer
Living organisms contain DNA, and sequencing DNA is a powerful way to understand how they respond to changing environments. The Biomolecule Sequencer experiment hopes to demonstrate (for the first time) that DNA sequencing is feasible in an orbiting spacecraft. Why? A space-based DNA sequencer could identify microbes, diagnose diseases and understand crew member health, and potentially help detect DNA- based life elsewhere in the solar system.
Ant-stronauts
Yes, ant-stronauts…as in ants in space. These types of studies provide insights into how ants answer collective search problems. Watching how the colony adapts as a unit in the quest for resources in extreme environments, like space, provides data that can be used to build algorithms with varied applications. Understanding how ants search in different conditions could have applications for robotics.
TAGES
The TAGES experiment (Transgenic Arabidopsis Gene Expression System) looks to see how microgravity impacts the growth of plant roots. Fluorescent markers placed on the plant’s genes allow scientists to study root development of Arabidopsis (a cress plant) grown on the space station. Evidence shows that directional light in microgravity skews root growth to the right, rather than straight down from the light source. Root growth patters on station mimic that of plants grown at at 45% degree angle on Earth. Space flight appears to slow the rate of the plant’s early growth as well.
Heart Cells
Spaceflight can cause a suite of negative health effects, which become more problematic as crew members stay in orbit for long periods of time. Effects of Microgravity on Stem Cell-Derived Cardiomycytes (Heart Cells) studies the human heart, specifically how heart muscle tissue contracts, grows and changes in microgravity. Understanding how heart muscle cells change in space improves efforts for studying disease, screening drugs and conducting cell replacement therapy for future space missions.
Medaka Fish
Chew on these results…Jaw bones of Japanese Medaka fish in microgravity show decreased mineral density and increased volume of osteoclasts, cells that break down bone tissue. Results from this study improve our understanding of the mechanisms behind bone density and organ tissue changes in space.
These experiments, and many others, emphasize the importance of biological research on the space station. Understanding the potential health effects for crew members in microgravity will help us develop preventatives and countermeasures.

Perched at the rivers edge, this Pampiano Residence by Studio B consists of an addition to the existing house as well as a detached garage with a dwelling unit above. The new architecture reinterprets the existing house and marries the project as ‘a whole’ through its use of materials, patterns and massing.

Dolce Far Niente in Dance Sport
It wasn’t that long ago, when I set up a new training schedule for my partner and I: a plan with all the goals, the training sessions and the topics we wanted to improve. To be honest, I was proud of what I created, because it was so thought through along with a lot of things finally falling into place. Well, at least these were my thoughts – until I brought the plan for discussion to a private lesson with our coach…
I am so glad that I had a professional eye to look over this! When he saw the schedule, he nodded and then said: “Good work so far, but there is one crucial thing missing.” It was like a wakeup call when he told me: “I see everything in this plan, except for the time when you do nothing at all”. That was it! I totally forgot to plan the time for regeneration: one of the key components when it comes to successful training.
In a (dance)-society that is (mostly) driven by the words higher, faster, stronger, we all tend to forget that we only get better in the time we leave our bodies to regenerate. This doesn’t mean of course that we will get better by doing nothing at all. It’s all about doing nothing AFTER we have been working hard. For instance, if we want to make our muscles more powerful, they first have to be exhausted and then they need time to rebuild to an even stronger version. But also our brain needs downtime to process new information. If we learn something new, it’s first saved in the short-term memory and then by processing the information, it will probably be stored in the long-term memory. And as we all know, in sleep our brain consolidates memories best.
Active work demands for active recovery from the physical and mental demands, in order to improve what we are doing. This goes for nearly all aspects in life and also perfectly for dancing. What do I mean by “active recovery”? Here is a quick and personal list:

Low Impact Activities
It’s always great to go on a short, easy 15-minute-walk. You can also do a really low impact Yoga session or stretch a little bit. Everything that makes you feel calm, relaxed and refueled. But don’t overdo it! Really give your body a rest!

Nutrition
Of course and as always, what you put into your body is crucial. A balanced nutrition is key to your healthy body as well as active recovery. Try to really control the amounts and also the quality of food you are taking in, and your exhausted muscles will thank you. Not to mention, your concentration on the next lesson will be so much better. One really important tip to keep in mind is, that starving your body (in case you are trying to lose weight or you’ve been telling yourself that “you don’t have time to eat”) is not good for your recovery at all. It will stress your system even more and will not let your body improve.

Sleep
According to the National Sleep Foundation, Serena Williams, a really successful tennis player, enjoys to go to bed at 7pm in order to get enough sleep. I am not telling you, that this would also work for you, but it is worth giving a thought. I used her example to really emphasize on how important sleeping is, even more for people who are physically active. It doesn’t matter if you consider yourself as a serious athlete/artist, or if you are just in it for fun, but getting the right amount of sleep is decisive to your performance and also to your improvement. Adults between the age 18 and 64 need between 6 and 11 hours, while 7-9 hours of sleep are recommended. I understand that this is a lot of time, but, in my opinion, sleeping is not enough of a priority anymore. Find yourself a sleeping schedule and also keep it on the weekends. Turn off electronics, find your ideal light, sound and temperatures in your bedroom and give your system a chance to reboot.

Let go of the “Coulda Woulda Shoulda”
If you now come to the conclusion that some downtime for yourself is what you need, you also have to let go of all the Rumba Walks you could have practiced in that time. Really! Focus on relaxing, recovering and refueling your energy! And, stop overthinking all the things you could’ve, should’ve or would’ve been able to do then. Just enjoy the famous Dolce Far Niente. And, afterwards – Dance on, even better than before!
