Greater Adria, a lost continent hiding in plain sight
Most of it was eaten by Earth's mantle, but scraped-off bits survive in the Alps and other mountain ranges.
- Following a 10-year survey, geologists discover a lost continent in the Mediterranean.
- 'Greater Adria' existed for 100 million years, and was probably "great for scuba diving".
- Most of it has been swallowed up by Earth's mantle, but bits of it survive.

Move over, Atlantis. Not all lost continents are myths; here's one whose existence has just been verified by science. Greater Adria broke off from North Africa 240 million years ago. About 120 million years later, it started sinking beneath Southern Europe. But bits of it remain, scattered across local mountain ranges.
It's the geological similarities in those mountains that had led scientists to hypothesize the presence of an ancient continent in the Mediterranean. But the region's geology is so complex that only recent advances in computing—and a 10-year survey by an international team of scientists—were able to produce a geo-historical outline of that former land mass. This is the very first map of the world's latest lost continent (1).
The 100-million-year history of Greater Adria starts nearly a quarter of a billion years ago. The world was a very different place back then. It was just recovering from the Permian-Triassic extinction, which came pretty close to wiping out all life on Earth. The planet was repopulated by the first mammals and dinosaurs.
All together now: the supercontinent of Pangaea (335-175 million years ago).

Oblivious that biological imperative, Earth's geology was on a course of its own: fragmentation. At that time, the planet's land masses had coagulated into a single supercontinent, Pangaea.
Around 240 million years ago, a Greenland-sized piece of continental plate broke off from what would become North Africa and started drifting north. Between 120 and 100 million years ago, the continent smashed into Southern Europe. Even though the speed of that collision was no more than 3 to 4 cm per year, it ended up shattering the 100-km thick crust.
Most of the continental plate was pushed under Southern Europe and swallowed up by Earth's mantle, a process known as subduction. Seismic waves can still detect the plate, now stuck at a depth of up to 1500 km.
But some of the sedimentary rocks on top were too light to sink, so they were scraped off and got crumpled up—the origin of various mountain chains across the Mediterranean region: the Apennines in Italy, parts of the Alps, and ranges in the Balkans, Greece and Turkey.
Death and birth
Flowing from present to deep past, this time-lapse reconstruction of the geological history of the Mediterranean shows the death and birth (in that order) of Greater Adria in unprecedented amounts of detail.
Some bits of Greater Adria survived both the shave-off into mountainhood and death by subduction. "The only remaining part of this continent is a strip that runs from Turin via the Adriatic Sea to the heel of Italy's boot," says Douwe van Hinsbergen, Professor of Global Tectonics and Paleogeography at Utrecht University, and the study's principal researcher. That's an area geologists call 'Adria', so the team, consisting of scientists from Utrecht, Oslo and Zürich, called the lost continent 'Greater Adria'.
What was the continent like? A shallow continental shelf in a tropical sea, where sediments were slowly turned into rock, Greater Adria possibly resembled Zealandia, a largely submerged continent with bits sticking out (i.e. New Zealand and New Caledonia), or perhaps the Florida Keys, an archipelago of non-volcanic islands. Either way, dotted with islands and archipelagos above the water, and lots of coral below, it was "probably good for scuba diving," Van Hinsbergen says.
It took scientists this long to produce the first map of Greater Adria not just because the Mediterranean is, in the words of Van Hinsbergen, "a geological mess (…) Everything is curved, broken and stacked. Compared to this, the Himalayas represent a rather simpler system." Greater Adria perished by subduction and scraping-off. The Himalayas emerged by the collision of two continents.

The region also has a complex geopolitical makeup, obliging the researchers to piece together evidence from 30 different countries, from Spain to Iran, "each with its own geological survey, own maps, own ideas about evolutionary history. Research often stops at national borders."
- First off, that its hypothesis was right: Geological similarities across the Mediterranean really did point to a lost continent, now found.
- Secondly, the reconstruction of Greater Adria has also taught geologists that subduction is the basic way in which mountain belts are formed.
- They've also learned a great deal about volcanism and earthquakes, and "(we) can even predict, to a certain extent, what a given area will look like in the far future," van Hinsbergen says.
- Finally, and practically, these insights will help scientists and surveyors to identify and locate ore deposits and other useful materials in mountain belts.

Can thinking about the past really help us create a better present and future?
- There are two types of counterfactual thinking: upward and downward.
- Both upward and downward counterfactual thinking can be positive impacts on your current outlook - however, upward counterfactual thinking has been linked with depression.
- While counterfactual thinking is a very normal and natural process, experts suggest the best course is to focus on the present and future and allow counterfactual thinking to act as a motivator when possible.

What are upward and downward counterfactual thinking?
Image by one line man on Shutterstock<p><strong>What is upward counterfactual thinking?</strong></p><p>Upward counterfactual thinking happens when we look at a scenario and ask ourselves "what if" in terms of how our life could have turned out better. </p><p>Examples of upward counterfactual thinking are: </p><ul><li><em>"I wish I had taken that other job instead of this one 10 years ago - my life would be so much better if I had." </em></li><li><em>"I wish I would have gotten the part in that high school play, maybe I could have gotten into a theatre school and became an actor…"</em> </li></ul><p>Both of these examples have the ideology that if you had made different choices, your life right now would be improved. </p><p><strong>What is downward counterfactual thinking?</strong></p><p>Downward counterfactual thinking is, naturally, the opposite of upward counterfactual thinking in that we think about how things could have been worse if other decisions had been made. </p><p>Examples of downward counterfactual thinking are: </p><ul><li><em>"I'm so thankful I studied secondary education in university instead of psychology like I had originally planned - I love teaching high school kids and I never would have gotten to do that…" </em></li><li><em>"I'm so happy I left David when I got the chance, I can't imagine still being in an unhappy marriage with someone who doesn't support me…"</em> </li></ul><p>In these examples, we see the idea that if you had made different choices your life would not be as good as it is right now. </p>

How do upward and downward counterfactual thinking impact your life?
Photo by Brasil Creativo on Shutterstock<p>While many people don't see the point in "what if" scenarios, various studies have found that downward counterfactual thinking can be more associated with psychological health compared with upward counterfactual thinking. Not only that, but research has also shown upward counterfactual thinking can be linked with current and future depression.</p> <p><strong>Downward counterfactual thinking tends to be more associated with psychological health </strong></p><p>According to a <a href="http://journal.sjdm.org/jdm06136.pdf" target="_blank">2000 study</a>, downward counterfactual thinking can be linked with better psychological health compared to upward counterfactual thinking. More importantly, in cases where downward counterfactual thinking did lead to negative feelings, those feelings acted as something of a motivator for people to take productive actions to better their current situation. </p> <p><strong>Upward counterfactual thinking tends to be more associated with depression </strong></p><p><a href="https://www.sciencedirect.com/science/article/abs/pii/S0272735816301714#:~:text=An%20upward%20counterfactual%20(as%20opposed,Markman%20and%20McMullen%2C%202003)." target="_blank">According to a 2017 study</a> that pooled a sample of over 13,000 respondents, thoughts about "better outcomes" and regret (upward counterfactual thinking) were associated with current and future depression. </p> <p><strong>Downward counterfactual thinking can actually improve your relationships and is more often engaged in by women than men.</strong></p><p>In a <a href="https://dspace.sunyconnect.suny.edu/bitstream/handle/1951/67589/Studer_Thesis.pdf?sequence=1&isAllowed=y" target="_blank">2016 research paper submitted</a> to the Department of Psychology at the State University of New York at New Paltz, downward counterfactual thinking in regards to romantic relationships was associated with relatively positive relationship outcomes. Interestingly, women were more likely than men to engage in downward counterfactual thinking about their romantic life. </p> <p><strong>Upward counterfactual thinking can have some benefits in certain scenarios. </strong></p><p>When we look back after a failed test and think "I wish I would have studied more" - this motivates us to study harder the next time a test comes up. In this way, upward counterfactual thinking (or the negative version of "what if") can actually benefit us. </p> <p><strong>This can be difficult, though, because much of the time upward counterfactual thinking is more associated with a pessimistic outlook that can be unmotivating. </strong></p> <p>Thinking in the past tense can be motivational (and even healthy) at times, but the best thing to do is look forward. </p><p>While counterfactual thinking as a whole can be used to motivate us to make better choices or appreciate where we are in life, <a href="https://www.psychologytoday.com/us/blog/darwins-subterranean-world/201809/the-psychology-what-if" target="_blank">this Psychology Today</a> article suggests that we should come up with ways to move on and focus on the present and the future instead of the past. Using counterfactual thinking as a motivational tool can be very helpful if we don't get stuck in the "what if" mindset that tends to pull us out of the present and back into the past, where things will always remain the same. </p>
Despite fact check campaigns, anti-vaccination influence is growing.
- Despite announcing plans to combat disinformation, anti-vax groups continue to gain influence on Facebook.
- An analysis of over 1,300 Facebook pages with 100 million followers shows that anti-vaccination agendas are having a profound impact.
- Only 50 percent of Americans are certain they'll receive an approved COVID-19 vaccine.

There's no way to tell, but that's the thing about Facebook: it doesn't have to be true. Willis's claim, which he made in conjunction with a fundraising effort for the film, has been shared 4.4k times. Convincing his fanbase that perhaps tens of thousands of doctors aren't on board will be a Herculean task. </p><p>Media Matters notes the official-sounding National Vaccine Information Center (NVIC), which, though sounding governmental, opposes every effort to vaccinate children. Beginning in February, the organization's website started publishing a "<a href="https://www.nvic.org/vaccines-and-diseases/Reports/covid-19.aspx" target="_blank">special report</a>" on COVID-19, laying the groundwork for vaccination disinformation. </p><p style="margin-left: 20px;">"The first three installments of the 'special report' adopt right-wing themes unrelated to vaccines, such as the claim that public health orders that promote social distancing result in a 'loss of civil liberties' and subject Americans to 'quarantine shaming.'
