Nature-deficit disorder: What kids lose by not experiencing the outdoors enough
Research explains the positive impact and health benefits of children spending more time in nature.

Time spent in nature is beneficial for children's mental and physical health, research says.
- "Nature-deficit disorder" is the term coined by author Richard Louv, to help put a name to the ever-growing problems associated with children spending less time in nature.
- Research has provided evidence that prove Richard Louv's theories on the importance of nature to the human body and mind. This research proves a link between time spent in nature and improvements in areas such as motivation, problem-solving and self-esteem.
- There are many simple, actionable ways parents and educators of young children can incorporate nature back into the lives of children both in school and at home, such as starting outdoor playgroups or reintegrating nature into the school curriculum.
"Passion is lifted from the earth itself by the muddy hands of the young; it travels along grass-stained sleeves to the heart." - Richard Louv, Last Child in the Woods
The term "Nature-Deficit Disorder" was coined by Richard Louv, not to serve as a medical diagnosis, but to give meaning to a significant problem in modern society - the human costs of alienating ourselves from nature. There is an ever-growing gap between human beings and nature due to open green space being urbanized and large advancements in technology.
Since the term was coined in Louv's 2005 publication "Last Child in the Woods: Saving Our Children from Nature-Deficit Disorder", it has been used as a rallying point for a movement called the New Nature Movement that strives to reconnect children to nature and educate people on the health benefits nature can have on the human mind and body.

Many intriguing studies on this topic provide profound insight into what children are missing by not experiencing enough nature.
To summarize, a lack of vitamin D, increased symptoms of mental health conditions such as ADHD and a lack of motivation among children who spend less time in nature are among the key concerns of researchers who support Richard Louv's theory.
An important 2008 study by Susanna Huh and Catherine Gordon has suggested a strong link between the decline in outdoor activities and the dramatic rise in vitamin D deficiency. Vitamin D, which our bodies produce as a response to sun exposure, is essential for maintaining healthy bones and teeth and can also protect against diseases such as type 1 diabetes.
According to Louv: "Time in nature is not leisure time; it's an essential investment in our children's health (and also, by the way, in our own)."
Researchers have gathered evidence that proves exposure to nature is important to the physical and mental health of children
The American Institutes for Research (AIR) conducted another study in 2005 that focused on 255 sixth-grade students from elementary schools across California. These students attended three outdoor education programs between the months of September and November.
The study evaluated the children across eight different constructs: self-esteem, cooperation, conflict resolution, leadership, relationship with peers, problem-solving ability, motivation to learn and overall behavior in class.
The children were split into two camps: One group of students did the outdoor schooling sessions first, and the other group was used as a baseline and would do the same outdoor schooling sessions after the first program had finished.
Ten weeks after the first study concluded, the positive change in the children was very obviously noted in the post-experiment surveys, with the children who attended the outdoor schooling sessions first showing large improvements in the area of conflict resolution.
The remaining group of children who had not yet completed the outdoor schooling sessions scored significantly lower across 7 of the 8 constructs that were being measured.
The teachers of the children were also asked to submit surveys (separate from the surveys done by the researchers) about the children before and after the experiment. According to the before and after remarks of the teachers, the children who attended outdoor schooling in the first camp showed significant positive gains in the areas of self-esteem, problem-solving, motivation to learn, and behavior in class.
Along with these findings, it was also discovered that the students who attended the outdoor training sessions raised their grades in the science department by up to 27% (according to the pre-survey and post-survey answers). This increase in grades was maintained for up to 10 weeks following the program.
Another study, this time conducted in northeastern China in 2013, further supports the importance of nature in children's lives. This time, the study focused on the association between green-spaces that surrounded schools and the mental health condition of attention-deficit/hyperactivity disorder (ADHD).
Data for this particular study came from measuring the green spaces around the schools and two reports given at different times from the parents regarding potential ADHD symptoms in their children.
This data was collected over a span of 10 months and showed results from seven different cities. The study included almost 60,000 children between the ages of 2 and 17, from 94 schools around the country.
The results of this study showed that the levels of green-ness were linked to the incidence of ADHD behavior/symptoms in the children. Greater greenness levels around the school were significantly linked with lower odds of ADHD symptoms present in the children of that school.
How parents (and educators) can easily and affordably reconnect children with nature
There are many easy and affordable ways you can incorporate nature back into your child's life.

The urbanization of society and advances in technology (among other things) have made nature less accessible to our children. However, Richard Louv (and the researchers who have supported his theories) aren't just proving there is a problem - they are also providing communities ways to leap into action.
Parents who are looking for actionable ways to involve nature in their children's lives can do more than just let their children play outside an hour extra a day. Parents can push to become more involved in movements that place importance on nature-learning for kids, such as the Leave No Child Inside movement that has sprung up all over the United States and Canada.
Simple things such as starting an outdoor club with other parents who are interested in maintaining the connection between human beings and nature can be extremely beneficial. In Omaha, for example, a parent-lead association was created by 5 families that offer hands-on, nature-based play activities for children.
If you're an educator, one of the best things you can do to stop the ever-growing gap between our children and nature is to educate yourselves on the cognitive (and other) health benefits of allowing children to have more interactions in nature. Then share that knowledge with not just your students, but other educators as well.
The Children & Nature Network site is one of the best resources for re-integrating nature back into the lives of our children, offering links to many different research papers that give you information on the benefits of unstructured outdoor play to whole curriculums that can be based on outdoor learning."What would our lives be like if our days and nights were as immersed in nature as they are in technology?"

‘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.
- 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>Massive 'Darth Vader' isopod found lurking in the Indian Ocean
The father of all giant sea bugs was recently discovered off the coast of Java.
A close up of Bathynomus raksasa
- A new species of isopod with a resemblance to a certain Sith lord was just discovered.
- It is the first known giant isopod from the Indian Ocean.
- The finding extends the list of giant isopods even further.
The ocean depths are home to many creatures that some consider to be unnatural.

<p>According to<a href="https://www.livescience.com/supergiant-isopod-newfound-species.html" target="_blank" rel="dofollow"> LiveScience</a>, the Bathynomus genus is sometimes referred to as "Darth Vader of the Seas" because the crustaceans are shaped like the character's menacing helmet. Deemed Bathynomus raksasa ("raksasa" meaning "giant" in Indonesian), this cockroach-like creature can grow to over 30 cm (12 inches). It is one of several known species of giant ocean-going isopod. Like the other members of its order, it has compound eyes, seven body segments, two pairs of antennae, and four sets of <a href="https://www.livescience.com/supergiant-isopod-newfound-species.html" target="_blank" rel="noopener noreferrer dofollow">jaws</a>.</p><p>The incredible size of this species is likely a result of deep-sea gigantism.

A new study explains how a chaotic region just outside a black hole's event horizon might provide a virtually endless supply of energy.
- In 1969, the physicist Roger Penrose first proposed a way in which it might be possible to extract energy from a black hole.
- A new study builds upon similar ideas to describe how chaotic magnetic activity in the ergosphere of a black hole may produce vast amounts of energy, which could potentially be harvested.
- The findings suggest that, in the very distant future, it may be possible for a civilization to survive by harnessing the energy of a black hole rather than a star.
The ergosphere
<p>The ergosphere is a region just outside a black hole's event horizon, the boundary of a black hole beyond which nothing, not even light, can escape. But light and matter just outside the event horizon, in the ergosphere, would also be affected by the immense gravity of the black hole. Objects in this zone would spin in the same direction as the black hole at incredibly fast speeds, similar to objects floating around the center of a whirlpool.</p><p>The Penrose process states, in simple terms, that an object could enter the ergosphere and break into two pieces. One piece would head toward the event horizon, swallowed by the black hole. But if the other piece managed to escape the ergosphere, it could emerge with more energy than it entered with.</p><p>The movie "Interstellar" provides an example of the Penrose process. Facing a fuel shortage on a deep-space mission, the crew makes a last-ditch effort to return home by entering the ergosphere of a blackhole, ditching part of their spacecraft, and "slingshotting" away from the black hole with vast amounts of energy.</p><p>In a recent study published in the American Physical Society's <a href="https://journals.aps.org/prd/abstract/10.1103/PhysRevD.103.023014" target="_blank" style="">Physical Review D</a><em>, </em>physicists Luca Comisso and Felipe A. Asenjo used similar ideas to describe another way energy could be extracted from a black hole. The idea centers on the magnetic fields of black holes.</p><p style="margin-left: 20px;">"Black holes are commonly surrounded by a hot 'soup' of plasma particles that carry a magnetic field," Comisso, a research scientist at Columbia University and lead study author, told <a href="https://news.columbia.edu/energy-particles-magnetic-fields-black-holes" target="_blank" rel="noopener noreferrer">Columbia News</a>.</p>Ergosphere representation
<p>In the ergosphere of a rotating black hole, magnetic field lines are constantly breaking and reconnecting at fast speeds. The researchers theorized that when these lines reconnect, plasma particles shoot out in two different directions. One flow of particles shoots off against the direction of the spinning black hole, eventually getting "swallowed" by the black hole. But the other flow shoots in the same direction as the spin, potentially gaining enough velocity to escape the black hole's gravitational pull.</p><p>The researchers proposed that this occurs because the breaking and reconnecting of magnetic field lines can generate negative-energy particles. If the negative-energy particles get "swallowed" by the black hole, the positive particles would theoretically be exponentially accelerated.</p><p style="margin-left: 20px;">"Our theory shows that when magnetic field lines disconnect and reconnect, in just the right way, they can accelerate plasma particles to negative energies and large amounts of black hole energy can be extracted," Comisso said. "It is like a person could lose weight by eating candy with negative calories."</p>Black hole
Event Horizon Telescope Collaboration
<p>While there might not be immediate applications for the theory, it could help scientists better understand and observe black holes. On an abstract level, the findings may expand the limits of what scientists imagine is possible in deep space.</p><p style="margin-left: 20px;">"Thousands or millions of years from now, humanity might be able to survive around a black hole without harnessing energy from stars," Comisso said. "It is essentially a technological problem. If we look at the physics, there is nothing that prevents it."</p>A psychiatric diagnosis can be more than an unkind ‘label’
A popular and longstanding wave of thought in psychology and psychotherapy is that diagnosis is not relevant for practitioners in those fields.
