  • It's probably fair to say that just about everyone's brains this year have been dominated by this pandemic.
  • But other science stories did happen in 2020, including amazing discoveries about everything from dinosaurs to parasites.
  • We didn't get a chance to cover all of them, but now they're getting their chance to shine.
  • So here are three unbelievably cool stories you might have missed.
  • First, back in April, researchers settled a major argument about dinosaurs.
  • For a while, scientists had figured that pretty much all species of non-avian dinosaur were terrestrial — they could venture out into water every now and again, but they mainly stuck to dry land.
  • The major exception to this, however, is Spinosaurus aegypticus, often known as Spinosaurus for short.
  • Based on features like its long, narrow jaws and croc-like teeth, we thought it was at least semi-aquatic — maybe hunting along the rivers in northern Africa — although that idea was definitely met with some pushback.
  • Now, though, there seems to be strong evidence that it wasn't just prowling around rivers — it may have been a proper aquatic beast.
  • The key evidence was published on April 29th, and it comes from tail bones discovered in Morocco in 2018.
  • We don't have a ton of fossils of Spinosaurus, because they were accidentally destroyed in World War II, so this was a major find.
  • Researchers used the fossils to make a digital reconstruction of the whole animal, and they found that its tail would have looked a bit like a newt or crocodile's tail — long, flat, upright, and strong.
  • What's more, scientists also made and tested a robotic model of this tail, and found it could probably produce enough force to let the animal swim.
  • If this is confirmed, it would end a years-long argument, and really expand our picture of where dinosaurs lived and what they were capable of.
  • Next is a story about other swimming giants, also from April, and it involves a clever solution to a tricky puzzle.
  • In the spring, scientists figured out that we can use nuclear residue from Cold War tests to figure out how old whale sharks are.
  • Whale sharks are the largest living species of shark, and we want to understand and protect them, but that's easier said than done.
  • Like, one thing we'd love to know is their life history — things like how long they live and how fast they grow.
  • But there was a conundrum — researchers couldn't agree how to measure their age.
  • There are growth bands on their vertebrae, like tree rings, but studies were conflicted about if one ring equals one year, or just six months.
  • Well, turns out the secret to figuring it out was nuclear weapons tests, back in the 1950s and 60s.
  • Scientists realized those tests would have increased global atmospheric levels of a rare form — or isotope — of carbon, called carbon-14, and it would have been picked up and incorporated into the shark's bones.
  • So the scientists got vertebrae from two of the oldest deceased specimens available and compared the isotope levels in their vertebrae's bands to ocean water samples from years ago.
  • By looking at the bands and the amount of carbon-14 in each, they were able to figure out what year different bands were put down.
  • And with those landmarks in place, they finally put the original question to rest and concluded that each band equals one year.
  • Using this new knowledge, the scientists were also able to conclude that whale sharks grow more slowly and live longer than we'd generally assumed — something that could help us better understand these ocean giants and how their populations are doing.
  • Finally, in May, news broke about one of our most notorious diseases, one that's been plaguing us long before COVID-19 — malaria.
  • One of the signature signs of malaria is regular recurring fevers.
  • These happen because the malaria parasites enter and breed inside red blood cells, then burst out in a synchronized wave of new parasites and waste materials.
  • For the parasites, it's possibly a way to evade the immune system.
  • But for humans, all those waste materials trigger a fever.
  • But what's interesting is that, depending on the exact species of parasite, these waves can happen like clockwork.
  • Like, some species that infect humans trigger fevers every two days, others every three.
  • For a long time, we've thought that the parasites may be using the host's circadian rhythm to time things — basically, our daily internal clocks.
  • But in May, we got published evidence that the parasites use their own biological clock instead.
  • To figure this out, scientists bred mice to have different circadian rhythms, some normal, some longer, and some non-existent.
  • Then they infected the mice with the parasites, and they found the parasite cycle would kind of adjust to match their host, but not perfectly.
  • Also, the parasite cycle existed even in mice without consistent circadian clocks.
  • This all suggests that the parasites have their own clock, though it's kept in sync by cues from the host's body.
  • That helps the individual parasites sync up with each other.
  • The scientists even identified genes that might be behind this.
  • Now, there isn't a huge conclusion about how to treat malaria here — at least, not yet.
  • But it's completely possible that this hidden interaction is something we could tweak and exploit to our benefit to put another deadly disease to rest.
  • So 2020 has been quite a year, but in the science world, there's a lot to celebrate.
  • Some scientists have been tackling this pandemic, including studying the virus and potential treatments and vaccines.
  • Meanwhile, researchers like these have been pouring time and energy into conservation, natural history, and other diseases.
  • And in both cases, our understanding of the world is that much better for it.
