Question: How do parasites alter the course of evolution?\r\n
Carl Zimmer: Well parasites are a huge menace to any free living organism. For one there are just a whole bunch of them. There are a lot more of those parasites than there are of us, so perhaps four, five, six, seven parasites for every free living species. That’s one estimate I’ve seen, although I bet there is a lot more and so these things, these parasites they’re trying to use us and other hosts to make more copies of themselves. That’s what they do and in the process we can get pretty sick or die, so any kind of mutation that might give us a little bit of resistance, might be able to let us evade these parasites, is going to be incredibly valuable. It’s going to be strongly favored by natural selection. And so you can see the effect of parasites in lots of different ways. I mean you can just go through the genome, the human genome and see that, the fingerprints of parasites there. They’re all over the place. They have shaped genes that make our immune system better, able to recognize certain kinds of parasites for example. They have… In some parts of the world they have made people resistant to malaria by making their blood cells harder for the malaria parasite to invade and on the other hand we have also kind of reached kind of an uneasy kind of a detente with some parasites as well. If you go to a jungle and look at the people who live there and this can be in the jungles of Venezuela or in Central Africa or what have you, places far from medical care, people are loaded with parasites, particularly intestinal worms, but it generally doesn’t harm their health all that much and what is also interesting is that people in these parts of the world also don’t have a lot of allergies whereas if you were to go to a city in Venezuela for example you would find people who have very few of these parasites, but have lots of allergies and other kind of autoimmune disorders. So there is a theory that over the past century we have rid ourselves of a lot of these nasty parasites. I mean nobody wants hookworm, but the problem is that our immune systems had evolved to be in a kind of a balance with these parasites, so they would sort of hold them in check, but they would not attack them too severely and it appears that our immune systems have to learn to find this balance, but if we live a life that is in a sense to clean we can’t… our bodies don’t learn that balance and so we get thrown off and we might attack some meaningless thing like a piece of cat dander or a piece of mold and we totally overreact because our immune systems haven’t been trained to basically calm down. So parasites have affected us on all sorts of different levels.\r\n
Question: How can parasites affect brain chemistry?\r\n
Carl Zimmer: Now if you are a parasite very often you don’t just want to make your host sick. You actually have other things in mind. So for example, there is a fungus that lives inside of ants that’s called Cordyceps. Now the fungus has to get from one ant to the next and what it does is it is going to shower its spores down on healthy ants. Well what that means is it’s got to get up above those ants, so how does it do that? What it does is it infects an ant, so a spore gets into an ant and it sort of burrows its way in and it starts to branch out inside of the ant and if you cut these poor ants open they’re like… after awhile they’re just pure fungus inside, but they’re still alive and they look pretty normal. They’re going around their business, but eventually when the fungus is ready they get a signal and they get this urge to climb upwards and what they do is they climb up plants, typically trees or small bushes and they’ll go about two feet up and then they’ll find a leaf and they will go and they will perch on the underside the leaf, usually amazingly enough facing north by northwest. These ants they’re heeding this call that’s coming from within them to do this very specific thing and the reason they’re doing that is because it’s good for the fungus. So what it does is it puts the fungus up in the air above other ants and now the fungus can get ready to spread. What it does is it produces a stalk that pops out of the ant’s head. So this poor ant has this giant spike that grows up out of its head that’s covered in spores. The fungus meanwhile is spreading out of the ant’s legs and abdomen and is attaching itself to the leaf, so the ant is now being cemented to the leaf and the fungus is also hardening the exoskeleton of the ant in a sense. It’s making this very durable case, this shelter, kind of a house where it can live and where it can survive and by being on the underside of that leaf it’s protected from rain and it’s protected from intense sunlight. It’s in this perfect place for being a parasitic fungus and now the spores from the ant coming out of that spike can shower down on the ants below and infect them and make them suffer that same horrible fate.\r\n
Now that is just one example. I know dozens. There are probably hundreds of examples that scientists have documented of parasites manipulating the behavior of their host. Sometimes it’s going from one host to another in the same species. There are a lot of cases where what the parasite wants to do is get from one species to another species. So for example, there is a parasite called toxoplasma. It’s very common in birds and rats and so on. Lots of mammals can carry it, but they are not the host where toxoplasma can really reproduce or produce the next generation of toxoplasma. That host, what is called a final host is cats, so you’ve got toxoplasma in something like a rat for example and in order for it to complete its lifecycle it has got to get into a cat and rats are very good at not getting into cats. I mean that’s sort of what they’re on earth for, to avoid getting eaten by cats. They have an incredibly sensitive sense of smell and if they get the faintest whiff of cat odor they get very anxious and they look around. They take evasive action. They don’t want to get eaten. What is really remarkable about a rat infected with toxoplasma is that it looks totally normal except that it is no longer afraid of the smell of a cat. In fact, sometimes when toxoplasma gets into rats they actually seem to get a little curious. They say what is this, this looks interesting, I’m going to investigate this and so it appears that the toxoplasma is very precisely manipulating the rat brain, maybe by secreting certain kinds of chemicals to affect its whole network for processing fear and other kinds of emotions and so it may be making it an easier target for cats.\r\n
What makes this really intriguing is that about a quarter of all people on earth are infected with toxoplasma. We get it from lots of different places. So for example, the soil is actually a place where you can pick it up if a cat has left its droppings in the area. This is why pregnant women are not supposed to handle kitty litter because kitty litter may be loaded with toxoplasma. Now if you get infected with toxoplasma generally it’s not a big deal because what happens is you may feel a little fever, but then after awhile you recover and you’re fine. What has happened is that the toxoplasma has formed little cysts in your brain, thousands and thousands and thousands of cysts in your brain and it’s just hiding there. It’s just hanging out. It’s still alive. In fact, every now and then they might break out, but your immune system can sense that they’ve broken out and they attack them again and they go back into their cysts, so there is this balance that we strike. The reason that pregnant women aren’t supposed to handle kitty litter is because if the toxoplasma gets into their babies that’s when the trouble starts because the babies don’t have a mature immune system yet, so there is nothing there to keep toxoplasma in check and so it will replicate like crazy. It can cause brain damage. It’s not a good thing. So there we are, a billion people maybe, maybe two billion people with toxoplasma in their brains and we know that it can affect mammal brains and the fact is that a rat brain and a human brain aren’t all that different. In the really basic ways they’re quite similar. So is it possible that the toxoplasma is affecting people? It’s possible. The evidence is really… I’d say it’s pretty sketchy at this point, but it’s evidence that can’t be just dismissed out of hand. So for example, people with toxoplasma have been reported to get into more traffic accidents. So does this mean that they’re being more reckless, that they’re not being as anxious as a normal human or rat might be? I don’t know the answer to that, but the fact remains that we have these mind altering parasites in our brains and so I think we ought to figure out what they’re doing.\r\n
Question: How was the parasite that causes sleeping sickness almost eradicated, and what can still be done about it?\r\n
Carl Zimmer: There are lots of diseases in the tropics that we fortunately don’t have to contend with in places like the United States and we should consider ourselves fortunate because some of them are really horrendous. A particularly horrendous one is called Sleeping Sickness. Sleeping Sickness is caused by a single celled organism called a trypanosome and it looks like a little fluke or a kind of a flatworm under a microscope, but it’s obviously much tinier than that. They are carried inside certain kinds of flies in Africa and these flies will bite people and they will inject these parasites, the trypanosomes into these humans who then start to get sick and they develop something called Sleeping Sickness, which you know not surprisingly makes you very tired and rundown. The real problem is that unless you treat it, it is quite fatal and so it’s a serious problem in… particularly in the belt just below the Sahara. Now a hundred years ago it was quite a serious problem, much more serious than it is today, but it’s been gradually eradicated from a lot of places where it was a big problem. It was eradicated through good public health, through treating people and through trying to attack the populations of the flies to basically break the cycle of transmission and it has worked in a lot of places. And this is a story that has been replicated with a number of parasites, with for example, a parasite that causes something called River Blindness. It’s a worm that actually like gets into your system and can get into your eye and inflames your eye and scars it until you’re blind. That is being very nicely eradicated and other diseases as well. Sleeping Sickness was getting close to that kind of eradication or at least being really driven down to very tiny levels, but unfortunately the war in Sudan has given it a new lease on life and so there have been in the past ten or twenty years new flare-ups of Sleeping Sickness and so it’s a real testament to the devastation that war can have. It isn’t just people being killed by bullets. It’s also people being killed by parasites as well.

How would the ability to genetically customize children change society? Sci-fi author Eugene Clark explores the future on our horizon in Volume I of the "Genetic Pressure" series.
- A new sci-fi book series called "Genetic Pressure" explores the scientific and moral implications of a world with a burgeoning designer baby industry.
- It's currently illegal to implant genetically edited human embryos in most nations, but designer babies may someday become widespread.
- While gene-editing technology could help humans eliminate genetic diseases, some in the scientific community fear it may also usher in a new era of eugenics.
Tribalism and discrimination<p>One question the "Genetic Pressure" series explores: What would tribalism and discrimination look like in a world with designer babies? As designer babies grow up, they could be noticeably different from other people, potentially being smarter, more attractive and healthier. This could breed resentment between the groups—as it does in the series.</p><p>"[Designer babies] slowly find that 'everyone else,' and even their own parents, becomes less and less tolerable," author Eugene Clark told Big Think. "Meanwhile, everyone else slowly feels threatened by the designer babies."</p><p>For example, one character in the series who was born a designer baby faces discrimination and harassment from "normal people"—they call her "soulless" and say she was "made in a factory," a "consumer product." </p><p>Would such divisions emerge in the real world? The answer may depend on who's able to afford designer baby services. If it's only the ultra-wealthy, then it's easy to imagine how being a designer baby could be seen by society as a kind of hyper-privilege, which designer babies would have to reckon with. </p><p>Even if people from all socioeconomic backgrounds can someday afford designer babies, people born designer babies may struggle with tough existential questions: Can they ever take full credit for things they achieve, or were they born with an unfair advantage? To what extent should they spend their lives helping the less fortunate? </p>
Sexuality dilemmas<p>Sexuality presents another set of thorny questions. If a designer baby industry someday allows people to optimize humans for attractiveness, designer babies could grow up to find themselves surrounded by ultra-attractive people. That may not sound like a big problem.</p><p>But consider that, if designer babies someday become the standard way to have children, there'd necessarily be a years-long gap in which only some people are having designer babies. Meanwhile, the rest of society would be having children the old-fashioned way. So, in terms of attractiveness, society could see increasingly apparent disparities in physical appearances between the two groups. "Normal people" could begin to seem increasingly ugly.</p><p>But ultra-attractive people who were born designer babies could face problems, too. One could be the loss of body image. </p><p>When designer babies grow up in the "Genetic Pressure" series, men look like all the other men, and women look like all the other women. This homogeneity of physical appearance occurs because parents of designer babies start following trends, all choosing similar traits for their children: tall, athletic build, olive skin, etc. </p><p>Sure, facial traits remain relatively unique, but everyone's more or less equally attractive. And this causes strange changes to sexual preferences.</p><p>"In a society of sexual equals, they start looking for other differentiators," he said, noting that violet-colored eyes become a rare trait that genetically engineered humans find especially attractive in the series.</p><p>But what about sexual relationships between genetically engineered humans and "normal" people? In the "Genetic Pressure" series, many "normal" people want to have kids with (or at least have sex with) genetically engineered humans. But a minority of engineered humans oppose breeding with "normal" people, and this leads to an ideology that considers engineered humans to be racially supreme. </p>
Regulating designer babies<p>On a policy level, there are many open questions about how governments might legislate a world with designer babies. But it's not totally new territory, considering the West's dark history of eugenics experiments.</p><p>In the 20th century, the U.S. conducted multiple eugenics programs, including immigration restrictions based on genetic inferiority and forced sterilizations. In 1927, for example, the Supreme Court ruled that forcibly sterilizing the mentally handicapped didn't violate the Constitution. Supreme Court Justice Oliver Wendall Holmes wrote, "… three generations of imbeciles are enough." </p><p>After the Holocaust, eugenics programs became increasingly taboo and regulated in the U.S. (though some states continued forced sterilizations <a href="https://www.uvm.edu/~lkaelber/eugenics/" target="_blank">into the 1970s</a>). In recent years, some policymakers and scientists have expressed concerns about how gene-editing technologies could reanimate the eugenics nightmares of the 20th century. </p><p>Currently, the U.S. doesn't explicitly ban human germline genetic editing on the federal level, but a combination of laws effectively render it <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">illegal to implant a genetically modified embryo</a>. Part of the reason is that scientists still aren't sure of the unintended consequences of new gene-editing technologies. </p><p>But there are also concerns that these technologies could usher in a new era of eugenics. After all, the function of a designer baby industry, like the one in the "Genetic Pressure" series, wouldn't necessarily be limited to eliminating genetic diseases; it could also work to increase the occurrence of "desirable" traits. </p><p>If the industry did that, it'd effectively signal that the <em>opposites of those traits are undesirable. </em>As the International Bioethics Committee <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">wrote</a>, this would "jeopardize the inherent and therefore equal dignity of all human beings and renew eugenics, disguised as the fulfillment of the wish for a better, improved life."</p><p><em>"Genetic Pressure Volume I: Baby Steps"</em><em> by Eugene Clark is <a href="http://bigth.ink/38VhJn3" target="_blank">available now.</a></em></p>
The newly discovered galaxies are 62x bigger than the Milky Way.
- Two recently discovered radio galaxies are among the largest objects in the cosmos.
- The discovery implies that radio galaxies are more common than previously thought.
- The discovery was made while creating a radio map of the sky with a small part of a new radio array.
An extremely active galaxy<p> <br> </p><p>Radio galaxies are galaxies with extremely active central regions, known as nuclei, which shine incredibly brightly in some part of the electromagnetic spectrum. They are known for emitting large jets of ionized matter into intergalactic space at speeds approaching that of light. They are related to quasars and blazars. It is thought that supermassive black holes are the energy source that make these galaxies shine so brightly. </p><p>What makes these two galaxies (known as MGTC J095959.63+024608.6 and MGTC J100016.84+015133.0) so interesting is their size. Only 831 similar, "giant radio galaxies" are known to exist. As study co-author Dr. Matthew Prescott explains, these are particularly large even for <a href="https://www.forbes.com/sites/jamiecartereurope/2021/01/18/we-just-found-two-mysterious-galaxies-62-times-bigger-than-our-milky-way-say-scientists/?sh=76edf29c2892" target="_blank" rel="noopener noreferrer">giants</a>:</p><p>"These two galaxies are special because they are amongst the largest giants known, and in the top 10 percent of all giant radio galaxies. They are more than two mega-parsecs across, which is around 6.5 million light-years or about 62 times the size of the Milky Way. Yet they are fainter than others of the same size."</p><p>The smaller of the two is just over two megaparsecs across, roughly six and a half million light-years. The larger is almost another half megaparsec larger than <a href="http://www.sci-news.com/astronomy/giant-radio-galaxies-09266.html" target="_blank">that</a>. <br></p><p>Exactly how these things get to be so massive remains a mystery. Some have proposed that they are ejecting matter into unusually empty space, allowing for the jet to expand further, though some evidence contradicts this. The most commonly suggested idea is that they are simply much, much older than the previously observed radio galaxies, allowing more time for expansion to occur.</p>
How does this change our understanding of the universe?<p> While exciting and impressive on their own, the findings also suggest that there are very many more of these giant galaxies than previously supposed. If you were going off the previous estimates for how typical these galaxies are, then the odds of finding these two would be 1 in 2.7×10<sup>6. </sup>This suggests that there must be more, given that the alternative is that the scientists were impossibly lucky. </p><p> In the study, the researchers also apply this reasoning to smaller versions of these galaxies, saying:</p><p> "While our analysis has considered only enormous (>2 Mpc) objects, if radio galaxies must grow to reach this size, then we may expect to similarly uncover in our data previously undetected GRGs with smaller sizes."</p><p> Exactly how common radio galaxies and turn out to be remains to be seen. Still, it will undoubtedly be an exciting time for radio astronomy as new telescopes are turned skywards to search for them.</p>

Daydreaming can be a pleasant pastime, but people who suffer from maladaptive daydreamers are trapped by their fantasies.

One maladaptive dreamer spent hours a day dreaming he was a powerful man who could solve the world's problems.
(Photo: Pixabay)<p>Daydreaming is an indulgence of the mind and imagination, one provided courtesy of the <a href="https://www.sciencedirect.com/topics/neuroscience/default-mode-network#:~:text=The%20default%20mode%20network%20(DMN,and%20Exercise%20Psychology%20Research%2C%202016" target="_blank">default mode network</a>, a network of interacting brain regions that is active even when the conscious mind is not. But like so many of life's indulgences—wine, steak dinners, video games, and even <a href="https://www.healthline.com/health-news/why-too-much-exercise-can-be-bad-042514" target="_blank">exercise</a>—too much daydreaming can be harmful to our well-being. When daydreaming crosses that threshold, it can be considered maladaptive.</p><p>This disorder was first identified by <a href="https://haifa.academia.edu/EliSomer" target="_blank">Eli Somer</a>, a professor of clinical psychology at the University of Haifa, School of Social Work, in <a href="https://link.springer.com/article/10.1023/A:1020597026919" target="_blank" rel="noopener noreferrer">a 2002 paper</a>. That paper looked to six patients in a trauma center whose daydreaming habits replaced human interactions or interfered with their standard life functions, such as going to school or holding down a job. </p><p>Since then, other case studies have looked at <a href="https://www.healthline.com/health/mental-health/maladaptive-daydreaming#:~:text=Maladaptive%20daydreaming%20is%20a%20psychiatric,life%20events%20trigger%20day%20dreams." target="_blank" rel="noopener noreferrer">maladaptive daydreamers</a> and compiled a list of potential symptoms. These include vivid, richly-detailed daydreams; abnormally long daydreaming sessions; daydreams triggered by real-life events; daydreaming sessions that interrupt sleep; and repetitive motions or whisperings while daydreaming. On average, one study reported, maladaptive daydreamers spend <a href="https://bigthink.com/bps-research-digest/people-with-maladaptive-daydreaming-spend-an-average-of-four-hours-a-day-lost-in-their-imagination" target="_self">four hours a day</a> housed in their imaginations.</p><p>"This is not like rehearsing a conversation that you might have with a boss," <a href="https://www.cnn.com/2016/12/30/health/maladaptive-daydreaming-feature/index.html" target="_blank" rel="noopener noreferrer">Somer told CNN</a>. "This is fanciful, weaving of stories. It produces an intense sense of presence."</p><p>While such symptoms are common, though not comprehensive or guaranteed, how maladaptive daydreams manifest are naturally individual to the dreamers. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6426361/" target="_blank" rel="noopener noreferrer">In one case study</a>, researchers analyzed the diary of a man codenamed "Peter." Peter described investing as many as 14 hours a day online. The news and images he happened upon would trigger related fantasies. For example, he may envision himself as a multimillionaire genius who could prevent bad news from occurring or self-insert himself into the power fantasies of superhero movies or police procedurals for hours at a time.</p><p>"When I felt this pain as a child, I started imagining how things could be different. I created stories which never happened. To suppress that pain I would hug my pillow or quilt, thinking I was being comforted by someone else," Peter wrote.</p><p>In an interview with CNN, Cordellia Rose described her maladaptive daydreaming like a drug and noted that her daydreams developed into intricate storylines that could last for years. These stories proved so distracted that she was unable to complete everyday tasks such as driving lessons.</p><p>"You get hooked on it, because it can be like an action movie in your head that's so gripping that you cannot turn off," Rose told CNN. "This [condition] needs to be public, because these are people suffering, and badly."</p><p>To be clear, maladaptive dreaming is not a <a href="https://www.webmd.com/schizophrenia/guide/what-is-psychosis#1" target="_blank" rel="noopener noreferrer">psychotic disorder</a> like schizophrenia. Daydreamers such as Peter and Rose are aware that their fantasies are as unreal as they may be unrealistic. Because of this, many maladaptive dreamers understand the difficulties they face and the real-life losses they have endured for the sake of their fantasies. </p>
More research needed<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="6fdb8ca5dcc87c58b441d9c7cd766f35"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/vI7b4_-MA8g?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>Researchers don't have a <a href="https://www.medicalnewstoday.com/articles/319400" target="_blank" rel="noopener noreferrer">standard diagnosis or treatment for maladaptive daydreaming</a> because they aren't yet sure it's a unique psychological condition. Maladaptive daydreaming has not been included in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition—blessedly abbreviated as the DMS-5—the definitive book on mental disorders. To date, there isn't enough evidence to determine if maladaptive daydreaming is a separate condition or a manifestation of an already listed disorder.</p><p>Somer has developed a <a href="https://www.sciencedirect.com/science/article/abs/pii/S1053810015300611" target="_blank" rel="noopener noreferrer">14-point scale</a> to help people determine whether they are experiencing maladaptive-daydreaming symptoms, but the results only indicate whether an individual should seek help. They provide no formal diagnosis.</p><p>Also, maladaptive daydreaming is often expressed alongside other conditions, such as anxiety disorders, <a href="https://www.psychiatryadvisor.com/home/topics/anxiety/ptsd-trauma-and-stressor-related/high-prevalence-of-maladaptive-daydreaming-among-patients-with-dissociative-disorders/" target="_blank" rel="noopener noreferrer">dissociative disorders</a>, attention deficit disorders, and obsessive-compulsive disorders. And the researchers of Peter's case study noticed a striking similarity between his condition and those with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3164585/" target="_blank" rel="noopener noreferrer">behavioral addition response</a>—including analogous responses with preoccupation, mood modification, tolerance, and withdrawal. It may be that maladaptive daydreaming is an expression of these, or other, disorders.</p><p>It's worth noting that similar empirical hurdles exist for other well-known, though not formalized, disorders. Orthorexia, sex addiction, misophonia, internet addiction, and parental alienation syndrome are all <a href="https://www.verywellmind.com/whats-missing-from-the-dsm-4145344#:~:text=This%20diagnosis%20covered%20patients%20who,%22%20or%20%22unspecified%20disorder.%22" target="_blank" rel="noopener noreferrer">likewise absent from the DSM-5</a>. For maladaptive daydreaming and these other conditions, it's simply a case of more evidence and research needed before a determination can be made.</p>
A growing understanding of maladaptive daydreaming<p>The question of labeling is a tricky one—not only from a medical point-of-view but also a prosocial one. Some people find having a recognized condition validating; they feel it promotes social acceptance and makes seeking treatment easier. Others find such labels stigmatizing and restricting.</p><p>But the question of how to label something is an academic one. It isn't to say that the experience doesn't exist. It does, and whether maladaptive daydreaming ultimately enters the DSM-5 or not, awareness is growing. <a href="https://daydreamresearch.wixsite.com/md-research/links" target="_blank">Online communities</a> now exist to give support and spread awareness. And regardless of a condition's presence in the medical literature, if symptoms disrupt work, school, or social lives, help should be sought.</p><p>Thanks to the efforts of psychologists and the community, maladaptive daydreaming, unlike Thurber's literary creation, is no longer "inscrutable to the last." And those who suffer it are no longer relegated to a firing-squad of their own mind but can find they help the need.</p>

Psychologists point to specific reasons that make it hard for us to admit our wrongdoing.
