Speaking of space…’Mighty Mice’ stay mighty muscular in space

While we are on the topic of research conducted by astronauts on the International Space Station (ISS), Space X’s 19th resupply mission to the ISS included studies that might help prevent muscle loss in astronauts as well as humans on Earth. While exercise programs have been developed for astronauts, these programs may not be as useful for long-distance space travel – such as a trip to Mars. This is where […]

A mother’s diet can have a lasting impact on offspring

A new study published in Physiological Reports provides evidence that a mother’s diet during pregnancy could have lasting impacts on her offspring’s bone development and later risk of osteoporosis. Osteoporosis is characterized by a loss of trabecular (spongy) bone leading to increased risk for developing bone fractures.  The researchers discovered this relationship while studying female microswine that were consuming a diet containing only 1% protein late in their pregnancy and for […]

Hypoxia and anoxia and reoxygenation, Oh my!

There are many examples of animals that can naturally tolerate hypoxic and anoxic conditions without exhibiting pathologies associated with reoxygenation. Here are a few examples from this year’s conference: Dr. Anthony Signore (University of Nebraska) spoke about how some hypoxia tolerant animals can use carbon monoxide, you know that gas we think of as poisonous, to improve oxygen binding to hemoglobin in hypoxic conditions. Well known for their ability to […]
