  • A Compass Works Differently in Space, Varying Widely From Planet to Planet
    www.discovermagazine.com
    Explorers have long trusted compasses to navigate Earths land and oceans, using our planets global magnetic field as their guide. But what happens when you take a compass beyond Earth into orbit, to the Moon, to other planets, or even beyond our solar system? Would it still point north, or would it aimlessly spin in the absence of a dominant magnetic field? The answer depends on where you are in the cosmos and what other magnetic fields are at play.On Earth, a compass needle aligns with our planets geomagnetic field, which is generated by the movement of molten iron in Earths outer core. This strong, bullet-shaped global magnetic field extends far beyond the surface of our planet. But as you venture farther and farther into space, the compass behavior can change. A Compass in Earth's OrbitEarths magnetic field, called the magnetosphere, bubbles out thousands of miles beyond Earths surface. But in low Earth orbit (LEO) where the International Space Station (ISS) circles the planet at an altitude of about 250 miles Earths magnetic field is nearly as strong as it is on the surface. That means a compass still works in orbit, aligning itself with Earth's magnetic north. (That is, provided there are no other strong magnets nearby.)However, coronal mass ejections (CMEs) and more powerful geomagnetic storms from the Sun can also interact with and disturb Earths magnetosphere, which can affect the direction a compass will point, especially the farther out you get. These fluctuations mean that although a compass in orbit would still roughly point north, it wouldnt be reliable enough for precise navigation. For example, even on Earths surface, navigation by compass is especially difficult during either of these magnetic storms because compass bearing can change by 10 degree or more during the course of a few hours, according to a NASA educator guide.Does a Compass Work on the Moon?The Moon, unlike Earth, no longer has a global magnetic field. This means a traditional compass will not work there. However, the Moon is not entirely devoid of magnetism. Certain lunar rocks have been found to have remanent magnetism meaning they were once exposed to a strong magnetic field billions of years ago and still produce weak, localized magnetic fields. Scientists do believe the Moon had a magnetic field billions of years ago that was roughly comparable in strength to Earths, generated by a now-extinct molten core dynamo. This ancient field likely even connected with Earths, according to NASA, creating a protective magnetosphere that shielded both bodies from solar wind and geomagnetic storms. But today, without a global magnetic field to guide it, a compass on the Moon would be useless.A Compass on Different PlanetsMagnetic fields vary widely across the solar system, which means a compass would behave differently on each planet:MercuryThis small, rocky planet has a weak but detectable global magnetic field, only about 1 percent the strength of Earths. A compass on Mercury could align with the field, but the needle's movements would be much more sluggish, and the direction it points could easily be influenced by the solar wind and the Suns powerful magnetic field.VenusVenus lacks an internally generated global magnetic field entirely. Therefore, a compass on the hellish planet would be as useless as one on the Moon. However, the compass may still act erratically if Venus has localized regions of magnetized crust, though evidence of this is still lacking. MarsAlthough Mars no longer has a global magnetic field, it did have one like Earths until about 3.5 billion years ago. And certain regions of Mars still contain remnants of that ancient global field embedded in the crust. A compass might react in some of these areas, but it wouldnt reliably function.JupiterThe gas and ice giants have intense magnetic fields, far stronger than Earths. A compass near Jupiter, for instance, would be overwhelmed by the planets complex and extremely powerful magnetosphere which is some 20,000 times the strength of Earths. Saturn Meanwhile, Saturns magnetic field is nearly perfectly aligned with its rotational axis, so a compass on the ringed planet might behave a bit more predictably. Uranus and NeptuneUranus and Neptune have magnetic fields that are both multipolar and tilted at extreme angles relative to their rotation, so a compass needle on either of these ice giants would act erratically and unpredictably. A Compass Outside the Solar SystemNear the heliopause the boundary where the Suns magnetic field gives way to the interstellar medium a compass would be primarily influenced by the magnetic fields of the Milky Way itself. However, these interstellar magnetic fields are extremely weak.In the Milky Ways galactic magnetic field, the force is so weak that a standard compass would be virtually useless. Although a traditional compass would essentially become dead weight between stars, galactic magnetic fields are still important because they help shape cosmic structures like nebulae and influence high-energy particles throughout the universe. Navigating the CosmosFor human and robotic explorers venturing beyond Earth, far more advanced navigation tools have replaced the simple compass. Whether its GPS, star trackers, or onboard magnetometers, space agencies have developed extremely reliable ways to traverse the cosmos. Still, imagining the behavior of a compass in environments far beyond Earth offers a fascinating glimpse into the invisible forces that shape our universe.Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.

  • Scientists finally figured out why tomatoes dont kill you
    www.popsci.com
    Tomatoes belong to the nightshade plant family, but genetic regulation keeps them safe to eat. Credit: Baac3nes / Getty ImagesShareThere was a time when tomatoes were a death sentenceat least, thats what many Europeans believed between the 16th and 18th centuries. And while they do belong to the nightshade plant family (Solanaceae), those poison apples werent really poisoning the aristocrats who ate them. Instead, its now understood that highly acidic tomatoes had a tendency to soak up the lead in pewter plates, resulting in fatal outcomes for many diners.But that doesnt change the fact that tomatoes, like their Solanaceae siblings, still produce toxic steroidal glycoalkaloids during their life cycles. So why is it fine to eat a BLT, but not the berries thought to have killed the Roman emperor Augustus? Researchers at Chinas Sichuan University recently got to the bottom of the chemical question. Their findings, as their Science AdvancesSteroidal glycoalkaloids evolved in Solanaceae plants to defend against pests. Ingesting a little too much of the molecule offers an unpleasantly bitter taste. In large enough quantities, steroidal glycoalkaloids can induce a range of far more serious symptoms including a burning sensation, nausea, cramps, slowed pulse and respiration, as well as stomach lesions and internal bleeding.But Solanaceae require seed propagation just like any other plant familyand thats often best achieved by animals eating their fruit, digesting the nutrients, and leaving the seeds behind in piles of natural fertilizer. So at some point in their maturation process, Solanaceae like tomatoes need to account for their poisonous steroidal glycoalkaloid levels. When and how that happened, however, has long remained a mystery.Researchers led by biologist Feng Bai have now identified the molecular systems responsible for this important tomato transition phase. To do this, they analyzed whole-genome bisulfite sequencing (WGBS) data and toyed with tomato genetics to block certain proteins.The results revealed that the same chemicals that cause tomatoes to ripen into redder, softer, and sweeter fruits also work to break down poisonous glycoalkaloids into the less toxic esculeoside A compound.

This process, known as demethylation, is vital in making tomatoes edible. When DML2 was blocked, however, tomato plants kept those same high levels of steroidal glycoalkaloids through fruit maturation.After comparing the genetic information with other similar plants, Bais team discovered tomatoes DML2-directed demethylation increased as humans learned to embrace and domesticate tomatoes over the past few centuries. But as tomatoes continue to grow larger, redder, and sweeter, they also exhibit increasingly lower levels of steroidal glycoalkaloid genes. This is how even green tomatoes can be fried and enjoyed, free from fear of death by those mythic poison apples.Whether or not you mind the pulpy insides of todays tomatoes, however, remains a matter of taste.

  • Why some chaos-seekers just want to watch the world burn
    www.sciencenews.org
    Since President Donald Trump took office a few weeks ago, the administrations frenetic activity, which has includedwithdrawing from global agreements and slashing slashing federal jobs and funding, has left many people reeling. Others, though, seem to be reveling in the chaos. According to political scientists, at least some of this chaos-seeking behavior may be intricately tied to peoples sense of losing their footing in society. And that sense, in turn, has ties to rising inequality and globalization.Chaos is a strategy that some people use to account for a perceived loss in status, says political scientist Kevin Arceneaux of the research university Sciences Po in Paris, France. Their reaction to that is to then start to create trouble, as a way to turn the cart on its head and try to reclaim their place.Most people prefer order, Arceneaux says. But about 15 percent of the U.S. population gravitates toward chaos, or a desire for a new beginning through the destruction of order and established structures, Arceneaux and his team reported in 2021 in Philosophical Transactions of the Royal Society B. The team reached that conclusion after developing a scale to measure peoples desire for chaos. Some 5,000 Americans rated their level of agreement with statements such as, I think society should be burned to the ground, I get a kick when natural disasters strike foreign countries and Sometimes I just feel like destroying beautiful things.Those highest in what Arceneaux calls chaos-seeking behavior 5 percent of the roughly 5,000 Americans surveyed seem keen to generate mayhem for mayhems sake without worrying about who gets hurt in the process, the team found. Meanwhile, roughly 10 percent of the people surveyed desire chaos but lack any ill intent, Arceneaux says. They just think society is too broken to be fixed. These folks want society to start over, but they dont want to hurt people, Arceneaux says.Science News spoke to Arceneaux to understand the role individual desires for chaos might be playing at this moment in U.S. and global history. This interview has been edited for length and clarity.SN: What prompted your team to start studying chaos?Arceneaux: It was probably early 2017. We had decided to start this research project to study misinformation. What was in the news at that time was that social media had been used for circulating a lot of false narratives. That really was the thing that we were interested in studying. And we conceptualized this concept [as] need for chaos.We started to dig into the academic literature on social marginalization [and] status seeking. The idea here is that there are some individuals who feel like theyre losing status. And this is a perception. These dont need to be people that are really destitute. They can actually be, in an absolute sense, well off. These individuals reaction to that perceived loss is to then try to create trouble.Then we developed the scale and we did a bunch of pilot studies. And then what we showed through a series of studies is that these individuals, clearly, their motivation for sharing misinformation is to just really stir up trouble, and they dont care if its true or not.Thankfully, its not a big group of people. At the same time, you dont need a big group of people to create chaos.SN: Youve analyzed how the need for chaos correlates with certain personality traits. According to your work, what characterizes chaos seekers?Arceneaux: There are two types of people that are high in chaos. A small group of people score highest on the scale. They want both society to burn to the ground and to destroy beautiful things. Theres another group thats a little bit bigger that we called rebuilders. They tended to say yes to burning institutions to the ground. But they dont want the malevolence. They dont get a kick out of natural disasters striking countries and things like that.Sponsor MessageChaos seekers seem to be driven by ego. They feel like theyre not being respected as much as they feel they should. But need for chaos is not a personality trait, where in every single context people are going to seek chaos. Instead, its something that psychologists call a character adaptation. These adaptations help people respond to a particular context. Right now, factors such as rising inequality and globalization are making life feel more precarious. So people high in darker personality traits might be responding by dialing up the chaos.Neither group [of chaos-seekers] is driven by a political ideology. In 2016 and in 2020, scoring high on the scale did not correlate with voting for Donald Trump. We have preliminary findings showing that people who scored high on the scale in 2024 were more likely to vote for Donald Trump. We dont know what changed.SN: Your research also suggests that chaos seekers skew white and male. Why do you think that is?Arceneaux: If you look at the Black individuals in our sample, theyre much more likely to be concerned about the group versus the individual than white individuals. Theres historically been much more emphasis on this notion of linked fate, that what happens to the group affects the individual.Among Black men and Black women and it looks like white women too if they feel like their group has lost, thats negatively correlated with need for chaos. And this seems to fit with what we know from the linked fate literature Youre a minority in a country where you feel like youre losing. Creating chaos isnt going to help you. It makes you a target.White men as a demographic show the strongest correlation between status loss and need for chaos. This fits with our theory. Its the personal status loss that motivates people. White men [more often] care that they individually are losing out.SN: Can this theory shed light on the current U.S. situation?Arceneaux: Theres no paper yet. But with [political scientist] Roy Truex, who is at Princeton [University], we did a study throughout the 2024 election.Starting in late July 2024, we surveyed 500 people across the United States every week up until Inauguration Day. Just before and after the election, I think we surveyed every day.We included the chaos scale on those surveys, questions to measure feelings of status loss and questions about peoples perception of their absolute status. We found people who feel like they are low in status are more likely to be high in need for chaos, which is consistent with the theory.Theres an old literature in social psychology around a concept called relative deprivation. It gets at this idea that when people think about how theyre doing, they think about it relative to other people. If youre my boss and you say, Im going to give you a 5 percent raise, that would be nice, right? But then if I find out that you gave my officemate a 10 percent raise, I feel like Im being screwed over. Thats classic relative deprivation. Whats interesting, though, is people who believe that they are high in status also score higher in need for chaos. Their concern seems to be losing that advantage.This is what happens when you have high levels of inequality. On the bottom, it creates a widespread sense of relative deprivation, of losing out But it also means that people at the very top can also become very worried about losing those things. Because the alternative to inequality is to share. Think about the arguments around DEI in the United States. People at the top might wonder: What does creating a more inclusive space mean for me?When I looked at this data, I thought, This is a really excellent explanation for why we have a marriage of two forces across the world. On the one hand, theres a group of people who do feel that the deck is stacked against them. And for them, starting over again or getting rid of the system as it is makes sense. But Elon Musk is the richest man in the world and Donald Trump is not poor. In Europe, a lot of the people who are leading the populist charge are not bad off either. One of the things thats possible is these folks recognize that theyve benefited and they want to keep that. Thats created strange bedfellows.SN:In your view, is there anything people can do to mitigate the chaos?Arceneaux: I think that we have to listen to some of these folks. Its easy to dismiss when people are saying, Look, Im getting screwed over, and say in response, You look like youre doing pretty good.A lot of people are asking: What are these liberal democratic institutions doing for me? What you get is a preference for a strong leader that will come in and clean things up. And we see that on the left and the right. In Venezuela, when Hugo Chavez came in, he was not on the right.I think we often think about this from the notion that theres nothing wrong with our democratic institutions. But I think we have to turn a little bit of attention to understanding why people are unhappy.

  • The butts of these blowfly larvae mimic termite faces
    www.sciencenews.org
    In the insect world, impostors could be hiding anywhere.When lifting a stone during an expedition in the Anti-Atlas Mountains in Morocco, researchers came across an unusual sight: three blowfly larvae living inside a termite nest.I immediately thought Wow, this is something cool, because Ive never seen anything like that, says entomologist Roger Vila of the Institute of Evolutionary Biology in Barcelona.Vila and colleagues brought the larvae and some termites to the lab, hoping to understand how the interlopers manage to get by unnoticed among harvester termites (Anacanthotermes ochraceus), which are known to kill intruders that enter their nests. The team examined the insects under the microscope, documented how the two species interacted and performed a number of experiments.The blowfly larvae bodies have evolved to closely resemble those of the termites, the researchers report February 10 in Current Biology. Inside the nest, termites recognize each other through touch, so having a termite-shaped body is crucial for larvae survival.On their rears, the larvae have features that resemble a termites antennae, eyes and other small structures, creating a false termite head. And tentacles around the body imitate termite antennae allowing the larvae to deceive termites coming from all sides.Scent also plays a role in the deception. In the dark underground, termites use chemical signals to recognize each other and each colony has a unique signature. If you throw there a termite from another colony, they kill it immediately, Vila says. The blowfly larvae, the researchers found, emit the exact scent that termites in the colony they exploit do.The larva also has tentacles around its body that mimic termite antennae, allowing the blowfly to trick termites it encounters at any side. R. VilaIt is unclear how blowfly larvae end up in the termite nest. The researchers speculate that adult blowflies lay their eggs around or inside of the nest, and that the termites adopt the impostors for unknown reasons. The larvae tend to stay in the most populated areas of the nest, the team says, so its possible that the termites might be feeding them. The blowflies belong to the Rhyncomya genus, but the exact species remains a mystery. A second expedition unearthed just two more larvae and no adults, which would help ID the species. That suggests it is exceptionally rare.Because other Rhyncomya species have larvae without mimicry, Vila says, this tells us that evolution can be very fast under some circumstances.
