6 reasons dogs truly are man’s best friend
Research suggests dog ownership may improve heart health, decrease depression, and even help you live longer.
- Dogs have been man's best friend for at least the past 15,000 years.
- Science now shows that this symbiotic relationship has been as beneficial for humans as their canine companions.
- Benefits of dog ownership include familial ties, a reduce risk of schizophrenia, and improved cardiovascular health.
Under cover of darkness, a pack of ancient wolves slowly stalk the camps of our nomadic ancestors. But they are not on the prowl. These timid, congenial Canidaes have discovered they can scavenge human kills and midden piles for more reward, and far less risk, than the hunt.
Over successive generations, their offspring grow more docile and more dependent on their human benefactors. In time humans adopt these four-legged moochers, taking them into their service with the tacit agreement of better food and companionship. And so, the human-dog relationship was born.
That's one possibility at least. All that's generally agreed upon is that dogs became man's best friend as early as 15,000 years ago — though some fossil evidence suggests domestication as far back as 30,000 years. As science writer James Gorman points out, this means we loved our tail-wagging besties before inventing agriculture, language, or permanent homes and even before we domesticated cows, goats, and, of course, cats.
"As we became friends with them, they became friends with us, and we have a dependency that's charming," Bill Nye, science guy and lover of all good dogs, told us in a 2015 interview. "It's enriched both the dog lives and the human lives."
For humans, the perks of the dog-human relationship run much deeper than games of fetch or a handy excuse to go for a nice, long walk.
Dogs see us as family
Dogs see their people as family, and the feeling seems to be mutual.
It's not our imaginations or a poetic attempt to explain behavior through personification. Dogs do view their people as family.
Cognition scientists at Emory University placed dogs in an MRI machine and scanned their brains while presenting them with different odors. Some aromas were of food. Others were from other dogs. And some were from the dogs' human companions. The dogs' brains' reward centers lit up most when presented with the human scents, showing they prioritized human relationships.
These results bolstered other research that shows dogs act similarly to human sounds and that they are the only non-primates to run toward humans for protection and comfort.
Dogs reduce the risk of schizophrenia

Dogs may be able to curb the risk of some mental diseases. That's the conclusion of research published in the peer-reviewed journal PLoS ONE, which found a link between dog ownership and a reduced risk of schizophrenia.
The researchers looked at 1,371 men and women across the socioeconomic spectrum. Roughly 400 participants suffered from schizophrenia, another 400 from bipolar disorder, and about 600 were controls. After a survey in which the participants were asked about pets, the researchers compared ownership with rates of mental illness.
They discovered that dog ownership before the age of 13 correlated with a 25 percent reduced risk of schizophrenia. Participants who owned dogs in the first years of life showed the largest protective effect.
"There are several plausible explanations for this possible 'protective' effect from contact with dogs," lead author Robert Yolken said in a statement. "Perhaps something in the canine microbiome that gets passed to humans and bolsters the immune system against or subdues a genetic predisposition to schizophrenia."
Sorry, ailurophiles. Cats did not show a similar link between ownership and a reduced risk of mental diseases.
Dogs are your heart's best friend, too
Regular walks with your dog is great exercise and boosts cardiovascular health.
The health benefits aren't just in the mind. Preliminary research published in Mayo Clinic Proceedings: Innovations, Quality & Outcomes suggests that pet ownership boosts heart health, especially if that pet is a dog.
Researchers evaluated roughly 1,800 participants using the American Heart Association's Life's Simple 7, seven life factors that people can improve to help achieve cardiovascular well-being. They then compared the health of pet owners with those who did not own pets and found a correlation between dog ownership and heart health. The researchers associated this salubrious effect with increased engagement and physical activity.
"In general, people who owned any pet were more likely to report more physical activity, better diet and blood sugar at an ideal level," Andrea Maugeri, a researcher with the International Clinical Research Center at St. Anne's University Hospital in Brno, said in a statement. "The greatest benefits from having a pet were for those who owned a dog, independent of their age, sex and education level."
Follow-up evaluations are scheduled until 2030.
Dogs make life better (and longer)

Better heart health means a better chance to live longer. That's according to a recent study and meta-analysis published in Circulation: Cardiovascular Quality and Outcomes.
The research found that dog owners who survived a heart attack were at a 33 percent reduced risk of early death compared to non-dog survivors. The same held true for stroke survivors (27 percent). Better still, dog ownership correlated with a 24 percent reduced risk of all-cause mortality, likely explained by an increase in physical activity and a decrease in depression and loneliness.
A study published in Scientific Reports corroborates a canine's life-giving, heart-healthy impact. The researchers reviewed the national registries for more than 3.4 million Swedes with no cardiovascular disease before 2001. Looking at the association between dog ownership and cardiovascular health, they found that single dog owners had a lowered risk of death, either due to cardiovascular disease (11 percent) or other causes (33 percent).
In a statement, lead junior author Mwenya Mubanga noted, "A very interesting finding in our study was that dog ownership was especially prominent as a protective factor in persons living alone, which is a group reported previously to be at higher risk of cardiovascular disease and death than those living in a multi-person household. Perhaps a dog may stand in as an important family member in the single households."
Dogs teach us ways to learn
Put simply, dogs are better at ignoring bad advice than their human peers. Research out of Yale University's Canine Cognition Center tasked dogs with retrieving treats from a puzzle. The researchers presented the steps to solve the puzzle but included many extraneous steps in the demonstration. When it was the dogs' turn, they nimbly skipped the unnecessary steps, thereby showing their ability to filter information effectively.
How did human children perform? Not so great. The children settled on pure imitation, regardless of whether a step proved useful in solving the puzzle.
"This tells us something really important about how humans learn relative to other animals," Big Think author Arpan Bhattacharyya wrote on the study. "We're really trusting of the information that we get from other individuals – even more trusting than dogs are.
"And what this means is we have to be really careful about the kinds of information we present ourselves with. We're not going to have the right filter for bad information, so we should stick to looking at information that's going to be positive, information that's going to be good."
Dogs teach us about ourselves
Dogs really do resemble their owners.
Dogs resemble their owners in more ways than floppy jowls or a perky gait. Dogs mirror their owners' personalities, and owners can use this information to better understand themselves.
Research published in the Journal of Research in Personality surveyed more than 1,600 dog owners, representing about 50 different breeds. They found that dog owners shaped their dogs' personalities. Extroverted owners rated their dogs as more active and playful, while the owners of more fearful dogs tended to exhibit more negative emotions. Similarly, more agreeable owners were guardians of less aggressive pets.
"We expected the dogs' personalities to be fairly stable because they don't have wild lifestyle changes humans do, but they actually change a lot. We uncovered similarities to their owners, the optimal time for training and even a time in their lives that they can get more aggressive toward other animals," lead author William Chopik said in a release.
Another study in Scientific Reports showed similar findings regarding stress. The researchers took hair and fur samples from owners and their dogs to measure both for the stress hormone cortisol. They found a correlation in long-term stress between the two.
More than simply good dogs
These are six ways that science has discovered dogs aid their interspecies partner. As genetic research advances, dogs may prove they are man's best friends in unforeseen ways. Scientists studying the canine genome have found a number of canine disorders that closely resemble those found in humans, including some cancers. Further study may provide a wealth of information that could help us solve our own genetic mysteries.

Emotional intelligence is a skill sought by many employers. Here's how to raise yours.
- Daniel Goleman's 1995 book Emotional Intelligence catapulted the term into widespread use in the business world.
- One study found that EQ (emotional intelligence) is the top predictor of performance and accounts for 58% of success across all job types.
- EQ has been found to increase annual pay by around $29,000 and be present in 90% of top performers.
Researchers hope the technology will further our understanding of the brain, but lawmakers may not be ready for the ethical challenges.
- Researchers at the Yale School of Medicine successfully restored some functions to pig brains that had been dead for hours.
- They hope the technology will advance our understanding of the brain, potentially developing new treatments for debilitating diseases and disorders.
- The research raises many ethical questions and puts to the test our current understanding of death.
What's dead may never die, it seems<p>The researchers did not hail from House Greyjoy — "What is dead may never die" — but came largely from the Yale School of Medicine. They connected 32 pig brains to a system called Brain<em>Ex</em>. Brain<em>Ex </em>is an artificial perfusion system — that is, a system that takes over the functions normally regulated by the organ. The pigs had been killed four hours earlier at a U.S. Department of Agriculture slaughterhouse; their brains completely removed from the skulls.</p><p>Brain<em>Ex</em> pumped an experiment solution into the brain that essentially mimic blood flow. It brought oxygen and nutrients to the tissues, giving brain cells the resources to begin many normal functions. The cells began consuming and metabolizing sugars. The brains' immune systems kicked in. Neuron samples could carry an electrical signal. Some brain cells even responded to drugs.</p><p>The researchers have managed to keep some brains alive for up to 36 hours, and currently do not know if Brain<em>Ex</em> can have sustained the brains longer. "It is conceivable we are just preventing the inevitable, and the brain won't be able to recover," said Nenad Sestan, Yale neuroscientist and the lead researcher.</p><p>As a control, other brains received either a fake solution or no solution at all. None revived brain activity and deteriorated as normal.</p><p>The researchers hope the technology can enhance our ability to study the brain and its cellular functions. One of the main avenues of such studies would be brain disorders and diseases. This could point the way to developing new of treatments for the likes of brain injuries, Alzheimer's, Huntington's, and neurodegenerative conditions.</p><p>"This is an extraordinary and very promising breakthrough for neuroscience. It immediately offers a much better model for studying the human brain, which is extraordinarily important, given the vast amount of human suffering from diseases of the mind [and] brain," Nita Farahany, the bioethicists at the Duke University School of Law who wrote the study's commentary, told <em><a href="https://www.nationalgeographic.com/science/2019/04/pig-brains-partially-revived-what-it-means-for-medicine-death-ethics/" target="_blank">National Geographic</a>.</em></p>
An ethical gray matter<p>Before anyone gets an <em>Island of Dr. Moreau</em> vibe, it's worth noting that the brains did not approach neural activity anywhere near consciousness.</p><p>The Brain<em>Ex</em> solution contained chemicals that prevented neurons from firing. To be extra cautious, the researchers also monitored the brains for any such activity and were prepared to administer an anesthetic should they have seen signs of consciousness. </p><p>Even so, the research signals a massive debate to come regarding medical ethics and our definition of death. </p><p>Most countries define death, clinically speaking, as the irreversible loss of brain or circulatory function. This definition was already at odds with some folk- and value-centric understandings, but where do we go if it becomes possible to reverse clinical death with artificial perfusion?</p><p>"This is wild," Jonathan Moreno, a bioethicist at the University of Pennsylvania, told <a href="https://www.nytimes.com/2019/04/17/science/brain-dead-pigs.html" target="_blank">the <em>New York Times</em></a>. "If ever there was an issue that merited big public deliberation on the ethics of science and medicine, this is one."</p><p>One possible consequence involves organ donations. Some European countries require emergency responders to use a process that preserves organs when they cannot resuscitate a person. They continue to pump blood throughout the body, but use a "thoracic aortic occlusion balloon" to prevent that blood from reaching the brain.</p><p>The system is already controversial because it raises concerns about what caused the patient's death. But what happens when brain death becomes readily reversible? Stuart Younger, a bioethicist at Case Western Reserve University, <a href="https://www.nature.com/articles/d41586-019-01216-4#ref-CR2" target="_blank">told <em>Nature</em></a> that if Brain<em>Ex</em> were to become widely available, it could shrink the pool of eligible donors.</p><p>"There's a potential conflict here between the interests of potential donors — who might not even be donors — and people who are waiting for organs," he said.</p><p>It will be a while before such experiments go anywhere near human subjects. A more immediate ethical question relates to how such experiments harm animal subjects.</p><p>Ethical review boards evaluate research protocols and can reject any that causes undue pain, suffering, or distress. Since dead animals feel no pain, suffer no trauma, they are typically approved as subjects. But how do such boards make a judgement regarding the suffering of a "cellularly active" brain? <a href="https://bigthink.com/philip-perry/after-death-youre-aware-that-youve-died-scientists-claim" target="_blank">The distress of a partially alive brain</a>? </p><p>The dilemma is unprecedented.</p>
Setting new boundaries<p>Another science fiction story that comes to mind when discussing this story is, of course, <em>Frankenstein</em>. As Farahany told <em>National Geographic</em>: "It is definitely has [sic] a good science-fiction element to it, and it is restoring cellular function where we previously thought impossible. But to have <em>Frankenstein</em>, you need some degree of consciousness, some 'there' there. [The researchers] did not recover any form of consciousness in this study, and it is still unclear if we ever could. But we are one step closer to that possibility."</p><p>She's right. The researchers undertook their research for the betterment of humanity, and we may one day reap some unimaginable medical benefits from it. The ethical questions, however, remain as unsettling as the stories they remind us of.</p>
Sharing QAnon disinformation is harming the children devotees purport to help.
- The conspiracy theory, QAnon, is doing more harm than good in the battle to end child trafficking.
- Foster youth expert, Regan Williams, says there are 25-29k missing children every year, not 800k, as marketed by QAnon.
- Real ways to help abused children include donating to nonprofits, taking educational workshops, and becoming a foster parent.
Real ways you can help stop child trafficking<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="21fc2dc85391501eec28c4bf46d7db15"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/AXL0q9jNZGU?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>Williams is the founder and CEO of <a href="http://www.seenandheard.org/" target="_blank">Seen and Heard</a>, a Los Angeles-based nonprofit that helps foster youth develop character through the performing arts. She's been involved with foster youth for years; I <a href="https://bigthink.com/politics-current-affairs/child-sex-trafficking" target="_self">wrote about her work</a> in child trafficking just over a year ago. Tragically, since that time, the situation for these children has only gotten worse, in large part because of QAnon.</p><p>Williams says child trafficking is an easy cause to rally people together. Fear is also a powerful unifying force, one that QAnon believers are already primed for via the news they consume. Almost every parent cares about their children, making them the ideal target to solidify groups. </p><p>The real problem, she says, is that the youth she works with are falling for these conspiracy theories. Trauma is a particularly powerful tool for indoctrination. If you're a teenager that's been abducted or abused, your trust level is already extremely low. Then you read about a global cabal of powerful men (and a few women) secretly abusing children, and the narrative seems ready-made for your personal history.</p><p>When Williams tried to "lovingly and kindly correct" the youth she was working with after learning about the Wayfair conspiracy, the girls' response was, "well, who owns the media?" </p><p style="margin-left: 20px;">"She goes from this small little thing to a QAnon talking point. I've been thinking about why she would believe such a preposterous idea—and there are others; it's not just one student, and they're in in deep. I think that when something horrific happens to you as a child, it's a lot easier to distance yourself from the immediate reality that it was an uncle or a parent or a sibling that hurt you. By detaching from that immediate person, they project it onto Bill Gates or Chrissy Teigen. Then it's not so personal, it's global." </p>

Photo by Joe Raedle/Getty Images<p>As Williams mentions, there are over 30,000 kids in foster care in the Los Angeles area alone. It's easy to fall through the cracks. The systems in place aren't perfect; they're certainly underfunded. When you're in a system trying to support you yet isn't capable of doing so, viewing the world as imperfect, and even harmful, becomes the lens through which you see reality. Again, this makes for a perfect indoctrination tool.</p><p>One popular QAnon talking point is that 800,000 children are missing. As Williams says, child trafficking experts "don't buy this for a minute." The number makes for a good meme but a poor representation of the problem. </p><p>To source better data, Williams turns to the <a href="https://www.missingkids.org/" target="_blank">National Center for Missing and Exploited Children</a> (NCMEC) and the <a href="https://www.fbi.gov/services/cjis/ncic" target="_blank" rel="noopener noreferrer dofollow">National Crime Information Center</a> (NCIC). An important factor when reading data: if a teacher <em>and</em> a caregiver report a missing child to NCIC, that counts as two children, not one, which accounts for some of the fluctuations in numbers. In total, between 25,000 and 29,000 kids go missing every year. Importantly, 94 percent of those children are recovered within four to six weeks. </p><p style="margin-left: 20px;">"They're not documenting the recovery rate. It's not like these numbers are perpetually hanging out there. So this 800,000 number is just ludicrous." </p><p>Williams compares what's going on to Black Lives Matter. Blacking out your Instagram profile picture is performative. It signals that you actually care, which is great, but if you're not supporting Black-owned businesses, for example, there are no teeth to your activism. </p><p>Of course, blacking out your profile doesn't cause the real-world harm the QAnon virus does. Sharing misinformation is ultimately harmful to the children in need of help. Williams offers the resources below—ranging from donations to nonprofits to educational trainings to becoming a foster parent—for people that actually want to do something to help victims of sexual and physical abuse. They might not make a great Twitter meme, but in the actual world, this support makes all the difference. </p><p><strong>To report abuse/neglect, call the child abuse hotline: 800.540.4000 (LA county) / 800.422.4453 (National)</strong></p><ul><li>Support anti-trafficking organizations by donating to <a rel="noopener noreferrer dofollow" href="http://savinginnocence.org/" target="_blank">Saving Innocence</a>, which runs the continuum of care from rescue to recovery, <a href="http://gozoe.org/" target="_blank" rel="noopener noreferrer dofollow">Zoe</a>, a reputable faith-based organization, and <a rel="noopener noreferrer dofollow" href="https://withtwowings.org/" target="_blank">Two Wings</a>, which helps to rehabilitate female survivors</li><li><a rel="noopener noreferrer dofollow" href="http://www.nolabrantleyspeaks.org/" target="_blank">Nola Brantley</a> offers in-person and online trainings to help combat the commercial sexual exploitation of children</li><li><a rel="noopener noreferrer dofollow" href="http://instagram.com/imrebeccabender" target="_blank">Rebecca Bender</a> is a trafficking survivor that runs "Myth Busters," which combats conspiracy theory disinformation</li><li>The <a href="https://www.instagram.com/missingkids/" target="_blank" rel="noopener noreferrer dofollow">National Center</a> of Missing and Exploited Children</li><li>Operation <a href="https://www.instagram.com/ourrescue/" target="_blank" rel="noopener noreferrer dofollow">Underground Railroad </a></li><li><a href="https://www.instagram.com/defendinnocence/" target="_blank" rel="noopener noreferrer dofollow">Defend Innocence</a> offers tips for parents and caregivers to keep kids safe</li></ul><p><span></span>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.

A 71% wet Mars would have two major land masses and one giant 'Medimartian Sea.'
- Sci-fi visions of Mars have changed over time, in step with humanity's own obsessions.
- Once the source of alien invaders, the Red Planet is now deemed ripe for terraforming.
- Here's an extreme example: Mars with exactly as much surface water as Earth.

Mars – and Martians – were a staple of 1930s pulp science fiction.

First serialised in 1936 as "Planet Plane" and set in the then distant future of 1981, the fourth novel by sci-fi legend John Wyndham (writing as John Benyon) could have been remembered mainly for its charming retro-futurism, if it weren't so blatantly, offhandedly misogynistic. </p><p>Fortunately, each era's sci-fi says more about itself than about the future. That also goes for how we see Mars. 'Classic' Martians, like the ones in H.G. Wells' "War of the Worlds," are creatures from a dying planet, using their superior firepower to invade Earth and escape their doom. That trope reflected 19th- and 20th-century fears about mechanized total warfare, which hung like a sword of Damocles over otherwise increasingly placid lifestyles. </p><p>Closer inspection of the Red Planet has revealed the absence of green men; and now <em>we're </em>the dying planet – pardon my Swedish.

Bhattarai, reproduced with kind permission; modified with MaptoGlobe<p>Mars's eastern continent is centered not on a plateau, but on a depression that on today's 'dry' Mars is called Hellas Planitia, one of the largest impact craters in the Solar system. On the 'wet' Mars of this map, the crater is the central and largest part of a sea that is surrounded by land, a Martian version of the Mediterranean Sea. Perhaps one day this Medimartian Sea will be the Mare Nostrum of a new civilization. </p><p>To the northeast of the circular semi-continent is a large island that on 'our' Mars is Elysium Mons, a volcano that is the planet's third-tallest mountain (14.1 km, 46,000 ft).</p><p>The map is the work of Aaditya Raj Bhattarai, a civil engineering student at Tribhuvan University in Kathmandu (Nepal). Talking to <a href="https://www.inverse.com/innovation/mars-with-water-map" target="_blank" rel="dofollow">Inverse</a>, he said he hoped his map could help further the Martian plans of Elon Musk and SpaceX: "This is part of my side project where I calculate the volume of water required to make life on Mars sustainable and the sources required for those water volumes from comets that will come nearby Mars in the next 100 years."<br></p><p><br></p><p><strong></strong><em>Images by Mr Bhattarai reproduced with kind permission.
