- There is a lot we can learn from the saliva in our mouths and the air in our homes.
- There are at-home DIY tests for just about everything, but not all of them are as accurate as they claim.
- From revealing the breed of your dog to testing your home for harmful gases, these kits are worth the money.
We've all heard the ads and seen the commercials. If you want to know where your great grandparents are from or if your beagle has a little golden retriever in him, there is a kit for that and it can be on your doorstep in 2 business days. The market for do-it-yourself medical kits is projected to reach $340 million by 2022, and with that comes more companies overselling themselves and their product as cheap alternatives to real science. Not all at-home test kits are bad, but some are more worth it than others.
Scientists and experts warn that consumers should proceed with caution when it comes to offering up their DNA and personal information. Adding your spit (or your dog's slobber) to a tube and blindly sending it to a PO Box across the country is not a small thing, which is why the reputation of those offering the services and reviews by independent parties are important. For the DIY kets on this list, we looked at recommendations from trusted sources, as well as online customer reviews to see which products delivered on their promises and which should be avoided. From radon testers to ancestry and health reports, here are 7 ways to discover more important information about your life.
Finally learn your dog's breed and if it is at risk of certain genetic diseases.
Dying to know what breed your adorable companion really is? This easy and affordable test can help! While scientists warn that the science of pet DNA tests is not yet perfect, the Embark Dog Breed + Health has a few things working in its favor. First and foremost, it was developed through a partnership with Cornell University College of Veterinary Medicine (one of the top veterinary colleges in the United States) and geneticist Spencer Wells. The doggie saliva swab test screens for 250 breeds and tests for over 170 genetic diseases, though a trusted doctor should be consulted before any treatment begins. Rescue moms and puppy pops reviewing the product on Amazon reported receiving their results in 2-7 weeks, but the wait is worth it.
If you suspect your home is hiding lead, this kit will help you know for sure.
According to the EPA, the older the house the more likely it is to contain lead-based paint. The U.S. government banned the use of lead-containing paint in 1978, but there are millions of homes that are still filled with the potentially hazardous material. Since 2008, only three lead test kits have been recognized by the agency's Lead Renovation, Repair and Painting (RRP) rule. 3M's Lead Check is listed as Amazon's Choice for such kits, and the reviews support the pick. The disposable swabs can be used on any surface. There are 8 in this pack, which should be enough to test every room in an average home. If lead is detected, the swabs turn pink in as little as 30 seconds, alerting the user that future steps need to be taken to ensure the safety of his/her family.
This popular ancestry and wellness test provides over 150 personalized reports.
Combining the company's ancestry service with health predisposition reports, this package deal is a bargain for the price. With only a swab of saliva, buyers can learn where their family hails from across 1500+ regions included in 23andMe's databases. The kit includes over 150 personalized genetic reports on variables such as traits, ancestry, wellness, and carrier status for numerous diseases, disorders, and deficiencies. 23andMe is the first direct-to-consumer DNA company to be granted FDA approval for tests associated with cancer risks, which has done a lot for their reputation in recent months.
Easily test your drinking water for bacteria, pesticides, and other contaminants.
According to a multi-test comparison conducted in 2012 by Good Housekeeping and the Water Sciences Laboratory at the University of Nebraska-Lincoln, the PurTest Water Analysis kit most accurately detected the things it said it would on the label. Using vials and test strips, the kit does not involve sending samples to a lab for analysis and does not have additional fees added onto the retail price. Everything you need to test up to 19 samples is right in the package, including a handbook and results sheet.
Radon is dangerous and it's important that your home be tested for it.
The second leading cause of lung cancer in the United States, radon is a naturally occurring radioactive gas that you do not want around your family and pets. Recommended by Consumer Reports as a great option for longer-term, more accurate testing, the Accustar Alpha Track Test Kit AT 100 is very easy to use. Once opened, the device is exposed to the air you want to test for between 3 months and a full year. It is then returned to Accustar's lab using a prepaid shipping label, and all you have to do is wait a few weeks for the very important results to arrive.
Take the guesswork out of identifying harmful mold and mycotoxins.
If you're concerned that a substance in your home may be mold but aren't ready to hire a professional inspector, this highly rated DIY Mold Test Kit may be the best solution. The product contains tape lift samples for surface testing as well as an inspection booklet so that at-home consumers know where and what to look for. The samples are shipped to a lab and once they are analyzed, the consumer receives an email with the findings. Lab fees are included in the buying price in every state except Texas, where an additional $24 fee is applied.
Bitten by a tick? Determine the tick's lyme disease status without a hospital or vet visit.
What do hikers, pet owners, hunters, and gardeners all have in common? A shared enemy: the deer tick. Finding one of those tiny bloodsuckers after a day outdoors can be scary. This kit allows for DNA-based screening to see if the culprit is a carrier of the disease Lyme borreliosis. Testing is provided by the Northeast Wildlife DNA Laboratory at East Stroudsburg University, with 99.9 percent accurate results delivered within three days of the lab receiving your samples.

‘Designer baby’ book trilogy explores the moral dilemmas humans may soon create
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.
18 January, 2021
Surprising Science
- 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.

<p>Imagine it's 2045. You start hearing rumors from your well-heeled friends about a mysterious corporation based on an undisclosed island that's offering an unprecedented service: the ability to genetically design your baby.</p><p>The baby will have some of your genetics, and some genetics from a sperm or egg donor, selected by you. But the rest of your child's genetic profile will be engineered by science. These changes will make it impossible for your child to develop genetic diseases. They'll also allow you to customize your child for dozens of traits, including intelligence level, emotional disposition, sexual orientation, height, skin tone, hair color, and eye color, to name a few. </p><p>This raises unsettling philosophical questions for some customers. "When does my child stop being my child?" they ask the corporate representatives. These wary customers are reminded of how risky it is to reproduce the old-fashioned way. The Better Genetics Corporation's motto sums it up: "Only God plays dice—humans don't have to."</p><p>This is the world described in a new science-fiction series by Eugene Clark titled <a href="http://bigth.ink/38VhJn3" target="_blank" rel="noopener noreferrer">"Genetic Pressure"</a>, which explores the moral and scientific implications of a future in which designer babies are becoming a major industry. The first book begins with the story of Rachel, a renowned horse breeder who befriends a billionaire client, and soon gets the funding to visit the tropical island on which the Better Genetics Corporation is headquartered. </p><p>There, corporate executives walk her through the process of designing a baby—an experience that feels like an uncanny mix between visiting a doctor and designing a luxury car. The series is told from multiple perspectives, serving as a deep dive into a complex moral web that today's scientists may already be weaving.</p>
<blockquote>[T]he introduction of designer babies would create a labyrinth of philosophical dilemmas that society is only beginning to explore. </blockquote>
<p>Case in point: In 2018, Chinese scientist He Jiankui announced that he had helped create the world's first genetically engineered babies. Using the gene-editing tool CRISPR on embryos, He Jiankui modified a gene called <a href="https://ghr.nlm.nih.gov/gene/CCR5" target="_blank">CCR5</a>, which enables HIV to enter and infect immune system cells. His goal was to engineer children that were immune to the virus.</p><p>It's unclear whether he succeeded. But what's certain is that the experiment shocked the international scientific community, which generally agreed that it's unethical to conduct gene-editing procedures on humans, given that scientists don't yet fully understand the consequences.</p><p>"This experiment is monstrous," Julian Savulescu, a professor of practical ethics at the University of Oxford, told <a href="https://www.theguardian.com/science/2018/nov/26/worlds-first-gene-edited-babies-created-in-china-claims-scientist" target="_blank"><em>The Guardian</em></a>. "The embryos were healthy. No known diseases. Gene editing itself is experimental and is still associated with off-target mutations, capable of causing genetic problems early and later in life, including the development of cancer."</p><p>Importantly, He Jiankui wasn't treating a disease, but rather genetically engineering babies to prevent the future contraction of a virus. These kinds of changes are heritable, meaning the experiment could have major downstream effects on future generations. So, too, would a designer-baby industry, even if scientists can do it safely.</p><p>With major implications on inequality, discrimination, sexuality, and our conceptions of life, the introduction of designer babies would create a labyrinth of philosophical dilemmas that society is only beginning to explore. </p>
<a href="http://bigth.ink/38VhJn3" ><img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTI2MTEzNi9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0NDcxMzY4M30.5fwCPH_6sQ0RF19aAH4FQFue9HFJykzdEc0Xka1TY04/img.jpg?width=980" id="affdd" class="rm-shortcode" data-rm-shortcode-id="76374e8775bd9441a338cf513bb1fa55" data-rm-shortcode-name="rebelmouse-image" data-width="924" data-height="520" /></a>
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>

There are 5 eras in the universe's lifecycle. Right now, we're in the second era.
Astronomers find these five chapters to be a handy way of conceiving the universe's incredibly long lifespan.

Surprising Science
- We're in the middle, or thereabouts, of the universe's Stelliferous era.
- If you think there's a lot going on out there now, the first era's drama makes things these days look pretty calm.
- Scientists attempt to understand the past and present by bringing together the last couple of centuries' major schools of thought.
<ul class="ee-ul"></ul>
<p>If you're fortunate enough to get yourself beneath a clear sky in a dark place on a moonless night, a gorgeous space-scape of stars waits. If you have binoculars and point them upward, you're treated to a mind-bogglingly dense backdrop of countless specks of light absolutely everywhere, stacked atop each other, burrowing outward and backward through space and time. Such is the universe of the cosmological era in which we live. It's called the Stelliferous era, and there are four others.</p>
The 5 eras of the universe
<p>There are many ways to consider and discuss the past, present, and future of the universe, but one in particular has caught the fancy of many astronomers. First published in 1999 in their book <a href="https://amzn.to/2wFQLiL" target="_blank"><em>The Five Ages of the Universe: Inside the Physics of Eternity</em></a>, <a href="https://en.wikipedia.org/wiki/Fred_Adams" target="_blank">Fred Adams</a> and <a href="https://en.wikipedia.org/wiki/Gregory_P._Laughlin" target="_blank">Gregory Laughlin</a> divided the universe's life story into five eras:</p><ul><li>Primordial era</li><li>Stellferous era</li><li>Degenerate era</li><li>Black Hole Era</li><li>Dark era</li></ul><p>The book was last updated according to current scientific understandings in 2013.</p><p>It's worth noting that not everyone is a subscriber to the book's structure. Popular astrophysics writer <a href="https://www.forbes.com/sites/ethansiegel/#30921c93683e" target="_blank">Ethan C. Siegel</a>, for example, published an article on <a href="https://www.forbes.com/sites/startswithabang/2019/07/26/we-have-already-entered-the-sixth-and-final-era-of-our-universe/#7072d52d4e5d" target="_blank"><em>Medium</em></a> last June called "We Have Already Entered The Sixth And Final Era Of Our Universe." Nonetheless, many astronomers find the quintet a useful way of discuss such an extraordinarily vast amount of time.</p>The Primordial era
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTEyMi9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyNjEzMjY1OX0.PRpvAoa99qwsDNprDme9tBWDim6mS7Mjx6IwF60fSN8/img.jpg?width=980" id="db4eb" class="rm-shortcode" data-rm-shortcode-id="0e568b0cc12ed624bb8d7e5ff45882bd" data-rm-shortcode-name="rebelmouse-image" data-width="1440" data-height="1049" />Image source: Sagittarius Production/Shutterstock
<p> This is where the universe begins, though what came before it and where it came from are certainly still up for discussion. It begins at the Big Bang about 13.8 billion years ago. </p><p> For the first little, and we mean <em>very</em> little, bit of time, spacetime and the laws of physics are thought not yet to have existed. That weird, unknowable interval is the <a href="https://www.universeadventure.org/eras/era1-plankepoch.htm" target="_blank">Planck Epoch</a> that lasted for 10<sup>-44</sup> seconds, or 10 million of a trillion of a trillion of a trillionth of a second. Much of what we currently believe about the Planck Epoch eras is theoretical, based largely on a hybrid of general-relativity and quantum theories called quantum gravity. And it's all subject to revision. </p><p> That having been said, within a second after the Big Bang finished Big Banging, inflation began, a sudden ballooning of the universe into 100 trillion trillion times its original size. </p><p> Within minutes, the plasma began cooling, and subatomic particles began to form and stick together. In the 20 minutes after the Big Bang, atoms started forming in the super-hot, fusion-fired universe. Cooling proceeded apace, leaving us with a universe containing mostly 75% hydrogen and 25% helium, similar to that we see in the Sun today. Electrons gobbled up photons, leaving the universe opaque. </p><p> About 380,000 years after the Big Bang, the universe had cooled enough that the first stable atoms capable of surviving began forming. With electrons thus occupied in atoms, photons were released as the background glow that astronomers detect today as cosmic background radiation. </p><p> Inflation is believed to have happened due to the remarkable overall consistency astronomers measure in cosmic background radiation. Astronomer <a href="https://www.youtube.com/watch?v=IGCVTSQw7WU" target="_blank">Phil Plait</a> suggests that inflation was like pulling on a bedsheet, suddenly pulling the universe's energy smooth. The smaller irregularities that survived eventually enlarged, pooling in denser areas of energy that served as seeds for star formation—their gravity pulled in dark matter and matter that eventually coalesced into the first stars. </p>The Stelliferous era
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTEzNy9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxMjA0OTcwMn0.GVCCFbBSsPdA1kciHivFfWlegOfKfXUfEtFKEF3otQg/img.jpg?width=980" id="bc650" class="rm-shortcode" data-rm-shortcode-id="c8f86bf160ecdea6b330f818447393cd" data-rm-shortcode-name="rebelmouse-image" data-width="481" data-height="720" />Image source: Casey Horner/unsplash
<p>The era we know, the age of stars, in which most matter existing in the universe takes the form of stars and galaxies during this active period. </p><p>A star is formed when a gas pocket becomes denser and denser until it, and matter nearby, collapse in on itself, producing enough heat to trigger nuclear fusion in its core, the source of most of the universe's energy now. The first stars were immense, eventually exploding as supernovas, forming many more, smaller stars. These coalesced, thanks to gravity, into galaxies.</p><p>One axiom of the Stelliferous era is that the bigger the star, the more quickly it burns through its energy, and then dies, typically in just a couple of million years. Smaller stars that consume energy more slowly stay active longer. In any event, stars — and galaxies — are coming and going all the time in this era, burning out and colliding.</p><p>Scientists predict that our Milky Way galaxy, for example, will crash into and combine with the neighboring Andromeda galaxy in about 4 billion years to form a new one astronomers are calling the Milkomeda galaxy.</p><p>Our solar system may actually survive that merger, amazingly, but don't get too complacent. About a billion years later, the Sun will start running out of hydrogen and begin enlarging into its red giant phase, eventually subsuming Earth and its companions, before shrining down to a white dwarf star.</p>The Degenerate era
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTE1MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxNTk3NDQyN30.gy4__ALBQrdbdm-byW5gQoaGNvFTuxP5KLYxEMBImNc/img.jpg?width=980" id="77f72" class="rm-shortcode" data-rm-shortcode-id="08bb56ea9fde2cee02d63ed472d79ca3" data-rm-shortcode-name="rebelmouse-image" data-width="1440" data-height="810" />Image source: Diego Barucco/Shutterstock/Big Think
<p>Next up is the Degenerate era, which will begin about 1 quintillion years after the Big Bang, and last until 1 duodecillion after it. This is the period during which the remains of stars we see today will dominate the universe. Were we to look up — we'll assuredly be outta here long before then — we'd see a much darker sky with just a handful of dim pinpoints of light remaining: <a href="https://earthsky.org/space/evaporating-giant-exoplanet-white-dwarf-star" target="_blank">white dwarfs</a>, <a href="https://earthsky.org/space/new-observations-where-stars-end-and-brown-dwarfs-begin" target="_blank">brown dwarfs</a>, and <a href="https://earthsky.org/astronomy-essentials/definition-what-is-a-neutron-star" target="_blank">neutron stars</a>. These"degenerate stars" are much cooler and less light-emitting than what we see up there now. Occasionally, star corpses will pair off into orbital death spirals that result in a brief flash of energy as they collide, and their combined mass may become low-wattage stars that will last for a little while in cosmic-timescale terms. But mostly the skies will be be bereft of light in the visible spectrum.</p><p>During this era, small brown dwarfs will wind up holding most of the available hydrogen, and black holes will grow and grow and grow, fed on stellar remains. With so little hydrogen around for the formation of new stars, the universe will grow duller and duller, colder and colder.</p><p>And then the protons, having been around since the beginning of the universe will start dying off, dissolving matter, leaving behind a universe of subatomic particles, unclaimed radiation…and black holes.</p>The Black Hole era
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTE2MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYzMjE0OTQ2MX0.ifwOQJgU0uItiSRg9z8IxFD9jmfXlfrw6Jc1y-22FuQ/img.jpg?width=980" id="103ea" class="rm-shortcode" data-rm-shortcode-id="f0e6a71dacf95ee780dd7a1eadde288d" data-rm-shortcode-name="rebelmouse-image" data-width="1400" data-height="787" />Image source: Vadim Sadovski/Shutterstock/Big Think
<p> For a considerable length of time, black holes will dominate the universe, pulling in what mass and energy still remain. </p><p> Eventually, though, black holes evaporate, albeit super-slowly, leaking small bits of their contents as they do. Plait estimates that a small black hole 50 times the mass of the sun would take about 10<sup>68</sup> years to dissipate. A massive one? A 1 followed by 92 zeros. </p><p> When a black hole finally drips to its last drop, a small pop of light occurs letting out some of the only remaining energy in the universe. At that point, at 10<sup>92</sup>, the universe will be pretty much history, containing only low-energy, very weak subatomic particles and photons. </p>The Dark Era
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTE5NC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0Mzg5OTEyMH0.AwiPRGJlGIcQjjSoRLi6V3g5klRYtxQJIpHFgZdZkuo/img.jpg?width=980" id="60c77" class="rm-shortcode" data-rm-shortcode-id="7a857fb7f0d85cf4a248dbb3350a6e1c" data-rm-shortcode-name="rebelmouse-image" data-width="1440" data-height="810" />Image source: Big Think
<p>We can sum this up pretty easily. Lights out. Forever.</p><p>Tonight, if it's clear, maybe you want to step outside, take a nice deep breath, and look up, grateful that we are where we are, and <em>when</em> we are, in spite of all the day's hardships. We've got a serious amount of temporal elbow room here, far more than we need, so not to worry, and those stars aren't going anywhere for a long, long time.</p>

Surprising Science
- Astronomers from Harvard and Smithsonian find a very rare "hot Jupiter" exoplanet without clouds or haze.
- Such planets were formed differently from others and offer unique research opportunities.
- Only one other such exoplanet was found previously.
<p><span style="background-color: initial;">Astronomers detected a first of its kind hot Jupiter-like planet without clouds or haze. Such p</span><span style="background-color: initial;">lanets are very rare, with only one exoplanet with a clear atmosphere previously found – that one classified as a "hot Saturn".</span></p><p>The "hot Jupiter" exoplanet WASP-62b is 75 light years away from Earth, coming in at about half the mass of our Jupiter. It completes a rotation around its sun in only 4.5 days (compared to 12 years for Jupiter). That closeness to the star makes the planet extremely hot. </p><p>The discovery was made by astronomers at the Center for Astrophysics | Harvard & Smithsonian. The gas giant was actually first located in 2012 using the Wide Angle Search for Planets (WASP) South survey. But the unique state of its atmosphere has only been understood now. </p>
<p>Munazza Alam, a graduate student from the Center for Astrophysics who led the study, was working on her thesis that involved exoplanet characterization when she zeroed in on the atmosphere of WASP-62b.</p><p>She used the Hubble Space Telescope for data and observations that were made via <em>spectroscopy</em>, a method of detecting chemical elements by studying electromagnetic radiation. In particular, Alam focused how WASP-62b looked as it came in front of its host star on three occasions. Observing visible light in such instances can show the existence of sodium and potassium in the atmosphere of the planet. The scientist could see no potassium but a complete fingerprint of sodium's presence. This led her team to conclude that the exoplanet's atmosphere lacked clouds or haze, which would have hidden the sodium's clear signature.</p>

<blockquote>"I'll admit that at first I wasn't too excited about this planet," Alam said in a <a href="https://www.cfa.harvard.edu/news/2021-01" target="_blank">press release</a>. "But once I started to take a look at the data, I got excited." Seeing the sodium was "the smoking gun evidence that we are seeing a clear atmosphere," she added.</blockquote><p>Finding such a planet is very unlikely since <a href="https://iopscience.iop.org/article/10.3847/2515-5172/aafc63" target="_blank">astronomers estimate</a> under 7% of exoplanets have clear atmospheres. Studying them can help us understand why they were formed in a way that is different from most planets, according to Alam. Without clouds and haze getting in the way, it is also easier to study the chemical makeup of such a planet.</p><p>Jupiter itself has a complex and chaotic cloud structure, formed at different altitudes:</p>

Surprising Science
- Scientists in Taiwan find the lair of giant predator worms that inhabited the seafloor 20 million years ago.
- The worm is possibly related to the modern bobbit worm (Eunice aphroditois).
- The creatures can reach several meters in length and famously ambush their pray.
<p>If you happened to be traversing the seafloor of Eurasia about 20 million years ago, you'd likely come across giant predator worms as long as several meters, claims new research. Scientists discovered that super-long worms may have taken over the ancient seafloor, based on their reconstructions of large burrows found at the bottom of the sea in northeast Taiwan.</p><p>The samples studied came from as far back as the Miocene epoch of 23 million to 5.3 million years ago. The research team used 319 specimens found in the sandstone of Yehliu Geopark, an area outside New Taipei City in Taiwan, to reconstruct a trace fossil dubbed <em>Pennichnus formosae.</em> Trace fossils are geological features such as burrows that can be used to make educated inferences about how ancient creatures behaved. The fossil uncovered by the researchers is comprised of an L-shaped burrow about 2 meters in length but only 2-3 centimeters in diameter. The scientists concluded that this fossil was probably left by gigantic sea worms, possibly the ancestors of the <em>bobbit worm</em> (Eunice aphroditois), which is still around today.</p>
<p><span style="background-color: initial;">The way a bobbit worm catches its food is by first hiding in a long burrow in the seafloor, then lunging up to catch its "</span><span style="background-color: initial;">unsuspecting prey with a snap of their powerful jaws," as the study authors <a href="https://www.nature.com/articles/s41598-020-79311-0" target="_blank">write</a>. The researchers believe the structure they found was created when the ancient worm retreated into the seafloor with its prey, still alive and struggling.</span></p><p>Ludvig Löwemark, a National Taiwan University paleontologist and the study's co-author, explained in an <a href="https://www.wired.com/story/is-this-a-fossilized-lair-of-the-dreaded-bobbit-worm/" target="_blank">interview</a> with Wired that the fossil they found shows invertebrates like the ancient worms were eating vertebrates. </p><p style="margin-left: 20px;">"Typically, what we find in the sedimentary record is animals that are moving through the sediment," said <a href="https://www.wired.com/story/is-this-a-fossilized-lair-of-the-dreaded-bobbit-worm/" target="_blank">Löwemark</a>. "But this is a record of a much more active behavior. The worms were actually hiding in the sediment, jumping out, catching their prey, and then dragging this prey down into the sediment."</p>

<p>What's also remarkable about the study is that studying ancient worms is generally an extremely difficult task. One big problem – they would have had bodies composed mainly of soft tissue, which is hard to preserve. The trace fossil discovered by the scientists is likely the first known fossil made by an ambushing predator of this kind.</p><p>If you're wondering, the bobbit worm's unusual name comes from a sordid episode of American culture, referencing the story of<a href="https://www.nytimes.com/2019/01/30/arts/television/lorena-bobbitt-documentary-jordan-peele.html" target="_blank"> John and Lorena Bobbitt</a>, who cut off her husband's penis after years of abuse.</p><p>Check out the study published in the journal <a href="https://www.nature.com/articles/s41598-020-79311-0" target="_blank" rel="noopener noreferrer">Scientific Reports.</a></p>
