Stem Cells Overcome Damage in Other Cells by Exporting Mitochondria

Anurag Agrawal and his research team at the CSIR-Institute of Genomics and Integrative
Biology in India have just identified a protein called Miro1 that encourages the transfer of
mitochondria to lung cells from mesenchymal stem cells. They found out about the proteins
power by testing the levels of therapeutic effectiveness with and without Miro1. The presence of
Miro1 is definitely correlated to an increase in the transfer of mitochondria to the lung cells.
When mitochondria are transferred back to the lungs like this, the EMBO Journal states, it can
help to rejuvenate damaged cells. This is important, because the mitochondria can help repair
tissue damage and inflammation that may be linked to asthma. They say that not only do the
mitochondria have these short term benefits, but they may help in the long run, too. It is
possible that the mesenchymal stem cells can even be shaped to make more efficient therapies
for lung disease.
I think this article is very interesting. It is awesome to know that through the basic science
processes of experimenting, we can learn more about how our bodies work. This impacts my
life, because this research team has possibly found a way to further therapeutically help those
with lung disease. With many people affected by lung disease, we should be grateful for the
work that this team has done. This relates to the subjects we have discussed, because it
directly relates to the cell cycle. When the mitochondria are sent back to the lung cells, the cells
are rejuvenated. This spark of life starts the growth and repair process toward having healthier
cells. We should care about this information, because it is the little findings like this that can
spark something new. If we can find even more proteins like Miro1 that help to revive the cellgrowth and repair, we might be able to cure lung disease forever. All it takes is one discovery
like this to spark this revolution.
Mathematical Study of Photosynthesis Clears the Path to Developing New Super Crops

Scientists like Dr. Iain Johnston from the Imperial College London and plant biologist Ben
Williams from the University of Cambridge have now identified the methods by which some
plants have developed extremely efficient photosynthesis systems. Only about 3% of all plants
use this type of advanced photosynthesis, but it makes them over 50% more efficient. When we
trace the evolutionary history back, we learn that both maize and sugar cane have these
capabilities, even though they evolved independently from one another and are not related.
Using math, we now know that these plants can take in more carbon dioxide from the

atmosphere, retain more water, and grow quicker. When all of these are put together, we result
in a plant that can improve the efficiency of photosynthesis.
This article made me think about all of the plants that we have in our world and how they used
to be different. Back before humans were here, the plants that we know today may not have
even existed, or been so primitive that we would not recognize them. This article is eye openingand helps you keep it in perspective. This impacts my life, because many food companies are
working to produce more efficient plants with bigger and more abundant crops. A good portion
of the food I eat may be food that has been a result of genetically modified crop systems. This
relates to the subjects we discussed, because it relates directly to photosynthesis. The reason
these plants are so efficient is because of the factors that go into the photosynthesis equation:
carbon dioxide, water, etc. We should care about this, because whether we like it or not, we will
always try to be more efficient. In trying to feed the ever-growing world, being able to grow
more food faster will (and already is) a high priority.
