ScienceActuallyOctopuses have three hearts: two just to pump blood through the gills and one more to circulate it to the organs. The circulating heart stops beating while an octopus swims, as swimming puts a lot of pressure on their bodies, making it harder for their hearts to pump blood.<a href="https://sfba.social/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#science</a> <a href="https://sfba.social/tags/sciencefacts" class="mention hashtag" rel="nofollow noopener" target="_blank">#sciencefacts</a> <a href="https://sfba.social/tags/octopus" class="mention hashtag" rel="nofollow noopener" target="_blank">#octopus</a> <a href="https://sfba.social/tags/octopuses" class="mention hashtag" rel="nofollow noopener" target="_blank">#octopuses</a> <a href="https://sfba.social/tags/heart" class="mention hashtag" rel="nofollow noopener" target="_blank">#heart</a> <a href="https://sfba.social/tags/swimming" class="mention hashtag" rel="nofollow noopener" target="_blank">#swimming</a> <a href="https://sfba.social/tags/swimmingisexhausting" class="mention hashtag" rel="nofollow noopener" target="_blank">#swimmingisexhausting</a>

ScienceActuallyLake Vostok, a subglacial lake buried under 2.5 miles (4 km) of Antarctic ice, has been completely cut off from sunlight, the atmosphere, and the rest of Earth for millions of years - and is teeming with life. Scientists drilled down and found thousands of microscopic organisms, including bacteria, fungi, and even signs of complex life.<a href="https://sfba.social/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#science</a> <a href="https://sfba.social/tags/sciencefacts" class="mention hashtag" rel="nofollow noopener" target="_blank">#sciencefacts</a> <a href="https://sfba.social/tags/lakevostok" class="mention hashtag" rel="nofollow noopener" target="_blank">#lakevostok</a> <a href="https://sfba.social/tags/subglaciallake" class="mention hashtag" rel="nofollow noopener" target="_blank">#subglaciallake</a> <a href="https://sfba.social/tags/life" class="mention hashtag" rel="nofollow noopener" target="_blank">#life</a> <a href="https://sfba.social/tags/antarctica" class="mention hashtag" rel="nofollow noopener" target="_blank">#antarctica</a>

ScienceActuallyOn September 3, 2002, astronomers discovered an asteroid with an unusual orbit around Earth. Further analysis of its trajectory and spectrographic evidence—specifically, the presence of titanium dioxide used in Apollo missions—revealed that it was actually the third stage of the Apollo 12 rocket, launched in 1969.<a href="https://sfba.social/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#science</a> <a href="https://sfba.social/tags/sciencefacts" class="mention hashtag" rel="nofollow noopener" target="_blank">#sciencefacts</a> <a href="https://sfba.social/tags/asteroid" class="mention hashtag" rel="nofollow noopener" target="_blank">#asteroid</a> <a href="https://sfba.social/tags/J002E3" class="mention hashtag" rel="nofollow noopener" target="_blank">#J002E3</a> <a href="https://sfba.social/tags/apollo12" class="mention hashtag" rel="nofollow noopener" target="_blank">#apollo12</a> <a href="https://sfba.social/tags/thirdstage" class="mention hashtag" rel="nofollow noopener" target="_blank">#thirdstage</a> <a href="https://sfba.social/tags/rocketstage" class="mention hashtag" rel="nofollow noopener" target="_blank">#rocketstage</a>

ScienceActuallyA humorous concept among the scientific community, often referred to as 'The Pizza Radius' or the 'Thermonuclear Culinary Zone,' suggests that for every nuclear explosion, there exists a precise mathematical distance where the heat flux would be just right to perfectly cook a frozen pizza.<a href="https://sfba.social/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#science</a> <a href="https://sfba.social/tags/sciencefacts" class="mention hashtag" rel="nofollow noopener" target="_blank">#sciencefacts</a> <a href="https://sfba.social/tags/pizza" class="mention hashtag" rel="nofollow noopener" target="_blank">#pizza</a> <a href="https://sfba.social/tags/frozenpizza" class="mention hashtag" rel="nofollow noopener" target="_blank">#frozenpizza</a> <a href="https://sfba.social/tags/nuclearexplosion" class="mention hashtag" rel="nofollow noopener" target="_blank">#nuclearexplosion</a> <a href="https://sfba.social/tags/pizzaradius" class="mention hashtag" rel="nofollow noopener" target="_blank">#pizzaradius</a> <a href="https://sfba.social/tags/thermonuclearculinaryzone" class="mention hashtag" rel="nofollow noopener" target="_blank">#thermonuclearculinaryzone</a>

ScienceActuallySperm whales have two nostrils, but unlike most animals, they are asymmetrically positioned. The left nostril is visible on the outside and forms the single blowhole used for breathing. The right nostril is hidden inside the whale’s massive head and is actually part of its complex echolocation system.Thanks for sharing, The Guernsey Scientist !<a href="https://sfba.social/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#science</a> <a href="https://sfba.social/tags/sciencefacts" class="mention hashtag" rel="nofollow noopener" target="_blank">#sciencefacts</a> <a href="https://sfba.social/tags/spermwhale" class="mention hashtag" rel="nofollow noopener" target="_blank">#spermwhale</a> <a href="https://sfba.social/tags/spermwhales" class="mention hashtag" rel="nofollow noopener" target="_blank">#spermwhales</a> <a href="https://sfba.social/tags/nostril" class="mention hashtag" rel="nofollow noopener" target="_blank">#nostril</a> <a href="https://sfba.social/tags/echolocation" class="mention hashtag" rel="nofollow noopener" target="_blank">#echolocation</a>

ScienceActuallyIn 2011, a vial of Scotch whisky distilled by Ardbeg was sent to the International Space Station (ISS) to study how microgravity affects the whisky's maturation process.

ScienceActuallySperm whales cuddle. These deeply social animals frequently swim close together, rubbing their bodies against one another. This tactile behavior is a form of bonding and likely provides comfort, much like a cuddle would for humans.Thanks for sharing, The Guernsey Scientist !<a href="https://sfba.social/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#science</a> <a href="https://sfba.social/tags/sciencefacts" class="mention hashtag" rel="nofollow noopener" target="_blank">#sciencefacts</a> <a href="https://sfba.social/tags/spermwhales" class="mention hashtag" rel="nofollow noopener" target="_blank">#spermwhales</a> <a href="https://sfba.social/tags/cuddle" class="mention hashtag" rel="nofollow noopener" target="_blank">#cuddle</a>
