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 […]

Researchers at Duke University recorded how long whales stay underwater during dives and made an impressive discovery. Some Cuvier’s beaked whales were capable of exceptionally long dives. While most dives were less than 78 minutes long, one animal performed a dive that lasted more than 3 hours! Interestingly, the recovery times from the dives did not appear to have a clear relationship with the dive duration. Researchers think these animals […]
Bats produce sounds to navigate their surroundings in a process called echolocation. The problem is that sound does not travel very well through air. To overcome this barrier, bats produce very high-intensity sounds. In fact, some bats can even produce sounds that are around 137 decibels sound pressure level (dB SPL), which is near the range that can cause hearing damage in people. Just like people, bats call at higher […]
