Time alone (chosen or not) can be a chance to hit the reset button
In order to gain more from spending time alone, it is important to be open to the benefits that solitude can bring.
Solitude has become a topic of fascination in modern Western societies because we believe it is a lost art – often craved, yet so seldom found.
It might seem as if we ought to walk away from society completely to find peaceful moments for ourselves. Yet there is a quote I really like from the book Solitude: In Pursuit of a Singular Life in a Crowded World (2017) by the Canadian journalist Michael Harris:
I don't want to run away from the world – I want to rediscover myself within it. I want to know what happens if we again take doses of solitude from inside our crowded days, along our crowded streets.
Steadily, slowly, research interest in solitude has been increasing. Note, solitude – time alone – is not synonymous with loneliness, which is a subjective sense of unwanted social isolation that's known to be harmful to mental and physical health. In contrast, in recent years, many observational studies have documented a correlation between greater wellbeing and a healthy motivation for solitude – that is, seeing solitude as something enjoyable and valuable. But, by itself, this doesn't prove that seeking solitude is beneficial. In science, to make such a causal statement, we'd need to isolate 'solitude' as the only variable, while holding other alternative explanations constant. That's a difficult challenge. In daily life, we spend time alone while also doing other things, such as working, grocery shopping, commuting, taking a walk, learning a hobby or reading a book. Arguably, with so many variations in the ways that people spend time alone, it is difficult to make a definitive statement that it is solitude per se that enhances our wellbeing.
By conducting experimental studies – in which volunteers spent time in controlled conditions in solitude or with others – a team of researchers, led by the clinical psychologist Netta Weinstein, now at the University of Reading, and me, overcame the shortcomings of the correlational research, shedding light on what solitude is really good for.
In one series of studies, we looked at how people's emotions changed after spending time alone. We measured positive emotions associated with high arousal, such as excitement and energisation, and positive emotions that are low in arousal, such as calmness and relaxation; we also measured high-arousal negative emotions, such as anger and anxiety, and low-arousal negative emotions, such as loneliness and sadness. By covering both poles of what psychologists call 'affective valence' (positive vs negative) and 'affective arousal' (high vs low), we demonstrated that time spent alone offers a unique opportunity for 'arousal regulation' – that is, both positive and negative forms of high arousal drop lower when we spend time alone. We called this the 'deactivation effect'.
While the deactivation effect was consistent across all the solitude and alone conditions that we devised, changes in low-arousal positive and negative affects depended on how motivated a person was to spend time alone. If volunteers embraced and enjoyed solitude for its benefits, they tended to experience an increase in positive low-arousal emotions – ie, to feel more relaxed and calm afterward – but if people didn't value spending time alone, they were more likely to experience an increase in negative low-arousal emotions – ie, to feel sad and lonely.
This means that, in order to gain more from spending time alone, it is important to be open to the benefits that solitude can bring. For many people now experiencing restrictions on their movements and their social lives, it will be a lonely time; for some of us, it might be a chance to try experiencing the benefits of unexpected solitude. While it might not improve our life as a whole, it can make momentary bouts of negative emotions more bearable.
If we can benefit from the deactivation effect (that is, lowering our levels of arousal) simply by spending time alone, does it matter whether we go on social media, during that time, or do something else? I get asked that question often. The evidence we've gathered suggests that browsing on your phone doesn't cancel out the deactivation effect. However, it takes away a different benefit of spending that time alone without an occupying activity: the opportunity for self-reflection.
In our studies, we define self-reflection as the act of attending to one's thoughts and feelings. In two experiments, we found that those who were in complete solitude, without a secondary activity, self-reflected more than those who read alone. Those who were alone, browsing on social media, were the least reflective. In fact, if you are someone who tends to be self-reflective, our research showed that time alone is most enjoyable if you allow yourself to sit in solitude rather than reading or using your phone.
Of course, this is not a new insight. It has been widely suggested in popular books and philosophical texts that time spent alone is good for self-reflection. Yet, not all self-reflection during time spent alone is qualitatively the same: it can be insightful or ruminative. In our current experiments, when Weinstein and I ask participants to describe a time when they were alone and felt inauthentic or 'not true' to themselves, this is characterised by the ruminative variety of self-reflection, filled with negative thoughts and regrets from which they couldn't get away.
When self-reflection turns sour and rumination takes over, mindful practices might be an effective strategy for some people to calm their repetitive negative thoughts. However, this suggestion should be taken with caution as mindfulness doesn't work for everyone and might be best practised in moderation. So, alternatively, it might not be a bad idea to break the solitude and reach out to a trusted friend, even if by a phone call or message. If you have a choice, it's never advisable to remain in solitude when it's no longer fruitful, particularly if you feel that rumination and worry are causing you distress.
Time alone is an opportunity for us to hit the reset button, to calm our high-arousal emotions. During the time we spend alone, we also have the option to seek complete solitude, to drop our daily activities and find a space to attend to our thoughts and emotions. Yet, if daily solitude is a lost art, as Harris suggests, how do we find the motivation to harvest it?
The answer depends on the individual but, surprisingly, not so much on whether you are an introvert or an extravert. Instead, our research shows that a healthy motivation for spending time alone is linked to a personality characteristic called 'dispositional autonomy', which describes people's capacity to regulate their daily experiences at will. Essentially, this means that embracing solitude is more about having the ability to self-regulate your emotions than about how introverted you happen to be.
People with an autonomous personality feel that they have chosen to do what they're doing, instead of seeing themselves as pawns at the mercy of the external environment. Having this approach to life is also about taking interest in every bit of your experience, trying out new experiences and exploring how you feel about them. Indeed, when we created a manipulation in the lab where some people were forced into experiencing solitude (thus reducing their sense of autonomy) and others were invited to take interest in it and try it out (fostering their autonomy), those who were forced into solitude saw less value in experiencing it and, in turn, derived less enjoyment from it.
It is important to note that all the volunteers tested in these studies were university students in the United States. Thus, these findings from 2017-19 tell us about the daily experiences with solitude of young adults in societies that offer easy access to many entertainment options and flexible working hours. In a culture fuelled by fast-paced lifestyles and convenient technologies, we are easily pulled by our devices and our obsession with productivity. When we are alone, we find ourselves working, and when we have a free moment, we want to catch up with what other people are doing by picking up our phones. This can be true even when people are in lockdown and unable to socialise in person. Such a mindset, in which we actively seek to avoid solitude, only increases the chance that we'll find the experience unpleasant when it arises. Conversely, by seizing the opportunity for relaxation and reflection afforded by moments (or even stretches) of solitude in our busy lives, we can reap the benefits. Time when we are unexpectedly alone can be difficult but, at least for some of us, it can also be a blessing in disguise.

Inventions with revolutionary potential made by a mysterious aerospace engineer for the U.S. Navy come to light.
- U.S. Navy holds patents for enigmatic inventions by aerospace engineer Dr. Salvatore Pais.
- Pais came up with technology that can "engineer" reality, devising an ultrafast craft, a fusion reactor, and more.
- While mostly theoretical at this point, the inventions could transform energy, space, and military sectors.
The U.S. Navy controls patents for some futuristic and outlandish technologies, some of which, dubbed "the UFO patents," came to light recently. Of particular note are inventions by the somewhat mysterious Dr. Salvatore Cezar Pais, whose tech claims to be able to "engineer reality." His slate of highly-ambitious, borderline sci-fi designs meant for use by the U.S. government range from gravitational wave generators and compact fusion reactors to next-gen hybrid aerospace-underwater crafts with revolutionary propulsion systems, and beyond.
Of course, the existence of patents does not mean these technologies have actually been created, but there is evidence that some demonstrations of operability have been successfully carried out. As investigated and reported by The War Zone, a possible reason why some of the patents may have been taken on by the Navy is that the Chinese military may also be developing similar advanced gadgets.
Among Dr. Pais's patents are designs, approved in 2018, for an aerospace-underwater craft of incredible speed and maneuverability. This cone-shaped vehicle can potentially fly just as well anywhere it may be, whether air, water or space, without leaving any heat signatures. It can achieve this by creating a quantum vacuum around itself with a very dense polarized energy field. This vacuum would allow it to repel any molecule the craft comes in contact with, no matter the medium. Manipulating "quantum field fluctuations in the local vacuum energy state," would help reduce the craft's inertia. The polarized vacuum would dramatically decrease any elemental resistance and lead to "extreme speeds," claims the paper.
Not only that, if the vacuum-creating technology can be engineered, we'd also be able to "engineer the fabric of our reality at the most fundamental level," states the patent. This would lead to major advancements in aerospace propulsion and generating power. Not to mention other reality-changing outcomes that come to mind.
Among Pais's other patents are inventions that stem from similar thinking, outlining pieces of technology necessary to make his creations come to fruition. His paper presented in 2019, titled "Room Temperature Superconducting System for Use on a Hybrid Aerospace Undersea Craft," proposes a system that can achieve superconductivity at room temperatures. This would become "a highly disruptive technology, capable of a total paradigm change in Science and Technology," conveys Pais.

Another invention devised by Pais is an electromagnetic field generator that could generate "an impenetrable defensive shield to sea and land as well as space-based military and civilian assets." This shield could protect from threats like anti-ship ballistic missiles, cruise missiles that evade radar, coronal mass ejections, military satellites, and even asteroids.
Dr. Pais's ideas center around the phenomenon he dubbed "The Pais Effect". He referred to it in his writings as the "controlled motion of electrically charged matter (from solid to plasma) via accelerated spin and/or accelerated vibration under rapid (yet smooth) acceleration-deceleration-acceleration transients." In less jargon-heavy terms, Pais claims to have figured out how to spin electromagnetic fields in order to contain a fusion reaction – an accomplishment that would lead to a tremendous change in power consumption and an abundance of energy.
According to his bio in a recently published paper on a new Plasma Compression Fusion Device, which could transform energy production, Dr. Pais is a mechanical and aerospace engineer working at the Naval Air Warfare Center Aircraft Division (NAWCAD), which is headquartered in Patuxent River, Maryland. Holding a Ph.D. from Case Western Reserve University in Cleveland, Ohio, Pais was a NASA Research Fellow and worked with Northrop Grumman Aerospace Systems. His current Department of Defense work involves his "advanced knowledge of theory, analysis, and modern experimental and computational methods in aerodynamics, along with an understanding of air-vehicle and missile design, especially in the domain of hypersonic power plant and vehicle design." He also has expert knowledge of electrooptics, emerging quantum technologies (laser power generation in particular), high-energy electromagnetic field generation, and the "breakthrough field of room temperature superconductivity, as related to advanced field propulsion."
Suffice it to say, with such a list of research credentials that would make Nikola Tesla proud, Dr. Pais seems well-positioned to carry out groundbreaking work.

The patents won't necessarily lead to these technologies ever seeing the light of day. The research has its share of detractors and nonbelievers among other scientists, who think the amount of energy required for the fields described by Pais and his ideas on electromagnetic propulsions are well beyond the scope of current tech and are nearly impossible. Yet investigators at The War Zone found comments from Navy officials that indicate the inventions are being looked at seriously enough, and some tests are taking place.

Gain-of-function mutation research may help predict the next pandemic — or, critics argue, cause one.
This article was originally published on our sister site, Freethink.
"I was intrigued," says Ron Fouchier, in his rich, Dutch-accented English, "in how little things could kill large animals and humans."
It's late evening in Rotterdam as darkness slowly drapes our Skype conversation.
This fascination led the silver-haired virologist to venture into controversial gain-of-function mutation research — work by scientists that adds abilities to pathogens, including experiments that focus on SARS and MERS, the coronavirus cousins of the COVID-19 agent.
If we are to avoid another influenza pandemic, we will need to understand the kinds of flu viruses that could cause it. Gain-of-function mutation research can help us with that, says Fouchier, by telling us what kind of mutations might allow a virus to jump across species or evolve into more virulent strains. It could help us prepare and, in doing so, save lives.
Many of his scientific peers, however, disagree; they say his experiments are not worth the risks they pose to society.
A virus and a firestorm
The Dutch virologist, based at Erasmus Medical Center in Rotterdam, caused a firestorm of controversy about a decade ago, when he and Yoshihiro Kawaoka at the University of Wisconsin-Madison announced that they had successfully mutated H5N1, a strain of bird flu, to pass through the air between ferrets, in two separate experiments. Ferrets are considered the best flu models because their respiratory systems react to the flu much like humans.
The mutations that gave the virus its ability to be airborne transmissible are gain-of-function (GOF) mutations. GOF research is when scientists purposefully cause mutations that give viruses new abilities in an attempt to better understand the pathogen. In Fouchier's experiments, they wanted to see if it could be made airborne transmissible so that they could catch potentially dangerous strains early and develop new treatments and vaccines ahead of time.
The problem is: their mutated H5N1 could also cause a pandemic if it ever left the lab. In Science magazine, Fouchier himself called it "probably one of the most dangerous viruses you can make."
Just three special traits

For H5N1, Fouchier identified five mutations that could cause three special traits needed to trigger an avian flu to become airborne in mammals. Those traits are (1) the ability to attach to cells of the throat and nose, (2) the ability to survive the colder temperatures found in those places, and (3) the ability to survive in adverse environments.
A minimum of three mutations may be all that's needed for a virus in the wild to make the leap through the air in mammals. If it does, it could spread. Fast.
Fouchier calculates the odds of this happening to be fairly low, for any given virus. Each mutation has the potential to cripple the virus on its own. They need to be perfectly aligned for the flu to jump. But these mutations can — and do — happen.
"In 2013, a new virus popped up in China," says Fouchier. "H7N9."
H7N9 is another kind of avian flu, like H5N1. The CDC considers it the most likely flu strain to cause a pandemic. In the human outbreaks that occurred between 2013 and 2015, it killed a staggering 39% of known cases; if H7N9 were to have all five of the gain-of-function mutations Fouchier had identified in his work with H5N1, it could make COVID-19 look like a kitten in comparison.
H7N9 had three of those mutations in 2013.
Gain-of-function mutation: creating our fears to (possibly) prevent them
Flu viruses are basically eight pieces of RNA wrapped up in a ball. To create the gain-of-function mutations, the research used a DNA template for each piece, called a plasmid. Making a single mutation in the plasmid is easy, Fouchier says, and it's commonly done in genetics labs.
If you insert all eight plasmids into a mammalian cell, they hijack the cell's machinery to create flu virus RNA.
"Now you can start to assemble a new virus particle in that cell," Fouchier says.
One infected cell is enough to grow many new virus particles — from one to a thousand to a million; viruses are replication machines. And because they mutate so readily during their replication, the new viruses have to be checked to make sure it only has the mutations the lab caused.
The virus then goes into the ferrets, passing through them to generate new viruses until, on the 10th generation, it infected ferrets through the air. By analyzing the virus's genes in each generation, they can figure out what exact five mutations lead to H5N1 bird flu being airborne between ferrets.
And, potentially, people.
"This work should never have been done"
The potential for the modified H5N1 strain to cause a human pandemic if it ever slipped out of containment has sparked sharp criticism and no shortage of controversy. Rutgers molecular biologist Richard Ebright summed up the far end of the opposition when he told Science that the research "should never have been done."
"When I first heard about the experiments that make highly pathogenic avian influenza transmissible," says Philip Dormitzer, vice president and chief scientific officer of viral vaccines at Pfizer, "I was interested in the science but concerned about the risks of both the viruses themselves and of the consequences of the reaction to the experiments."
In 2014, in response to researchers' fears and some lab incidents, the federal government imposed a moratorium on all GOF research, freezing the work.
Some scientists believe gain-of-function mutation experiments could be extremely valuable in understanding the potential risks we face from wild influenza strains, but only if they are done right. Dormitzer says that a careful and thoughtful examination of the issue could lead to processes that make gain-of-function mutation research with viruses safer.
But in the meantime, the moratorium stifled some research into influenzas — and coronaviruses.
The National Academy of Science whipped up some new guidelines, and in December of 2017, the call went out: GOF studies could apply to be funded again. A panel formed by Health and Human Services (HHS) would review applications and make the decision of which studies to fund.
As of right now, only Kawaoka and Fouchier's studies have been approved, getting the green light last winter. They are resuming where they left off.
Pandora's locks: how to contain gain-of-function flu
Here's the thing: the work is indeed potentially dangerous. But there are layers upon layers of safety measures at both Fouchier's and Kawaoka's labs.
"You really need to think about it like an onion," says Rebecca Moritz of the University of Wisconsin-Madison. Moritz is the select agent responsible for Kawaoka's lab. Her job is to ensure that all safety standards are met and that protocols are created and drilled; basically, she's there to prevent viruses from escaping. And this virus has some extra-special considerations.
The specific H5N1 strain Kawaoka's lab uses is on a list called the Federal Select Agent Program. Pathogens on this list need to meet special safety considerations. The GOF experiments have even more stringent guidelines because the research is deemed "dual-use research of concern."
There was debate over whether Fouchier and Kawaoka's work should even be published.
"Dual-use research of concern is legitimate research that could potentially be used for nefarious purposes," Moritz says. At one time, there was debate over whether Fouchier and Kawaoka's work should even be published.
While the insights they found would help scientists, they could also be used to create bioweapons. The papers had to pass through a review by the U.S. National Science Board for Biosecurity, but they were eventually published.
Intentional biowarfare and terrorism aside, the gain-of-function mutation flu must be contained even from accidents. At Wisconsin, that begins with the building itself. The labs are specially designed to be able to contain pathogens (BSL-3 agricultural, for you Inside Baseball types).
They are essentially an airtight cement bunker, negatively pressurized so that air will only flow into the lab in case of any breach — keeping the viruses pushed in. And all air in and out of the lap passes through multiple HEPA filters.
Inside the lab, researchers wear special protective equipment, including respirators. Anyone coming or going into the lab must go through an intricate dance involving stripping and putting on various articles of clothing and passing through showers and decontamination.
And the most dangerous parts of the experiment are performed inside primary containment. For example, a biocontainment cabinet, which acts like an extra high-security box, inside the already highly-secure lab (kind of like the radiation glove box Homer Simpson is working in during the opening credits).
"Many people behind the institution are working to make sure this research can be done safely and securely." — REBECCA MORITZ
The Federal Select Agent program can come and inspect you at any time with no warning, Moritz says. At the bare minimum, the whole thing gets shaken down every three years.
There are numerous potential dangers — a vial of virus gets dropped; a needle prick; a ferret bite — but Moritz is confident that the safety measures and guidelines will prevent any catastrophe.
"The institution and many people behind the institution are working to make sure this research can be done safely and securely," Moritz says.
No human harm has come of the work yet, but the potential for it is real.
"Nature will continue to do this"
They were dead on the beaches.
In the spring of 2014, another type of bird flu, H10N7, swept through the harbor seal population of northern Europe. Starting in Sweden, the virus moved south and west, across Denmark, Germany, and the Netherlands. It is estimated that 10% of the entire seal population was killed.
The virus's evolution could be tracked through time and space, Fouchier says, as it progressed down the coast. Natural selection pushed through gain-of-function mutations in the seals, similarly to how H5N1 evolved to better jump between ferrets in his lab — his lab which, at the time, was shuttered.
"We did our work in the lab," Fouchier says, with a high level of safety and security. "But the same thing was happening on the beach here in the Netherlands. And so you can tell me to stop doing this research, but nature will continue to do this day in, day out."
Critics argue that the knowledge gained from the experiments is either non-existent or not worth the risk; Fouchier argues that GOF experiments are the only way to learn crucial information on what makes a flu virus a pandemic candidate.
"If these three traits could be caused by hundreds of combinations of five mutations, then that increases the risk of these things happening in nature immensely," Fouchier says.
"With something as crucial as flu, we need to investigate everything that we can," Fouchier says, hoping to find "a new Achilles' heel of the flu that we can use to stop the impact of it."
From "mutilated males" to "wandering wombs," dodgy science affects how we view the female body still today.
- The history of medicine and biology often has been embarrassingly wrong when it comes to female anatomy and was surprisingly resistant to progress.
- Aristotle and the ancient Greeks are much to blame for the mistaken notion of women as cold, passive, and little more than a "mutilated man."
- Thanks to this dubious science, and the likes of Sigmund Freud, we live today with a legacy that judges women according to antiquated biology and psychology.
The story of medicine has not been particularly kind to women. Not only was little anatomical or scientific research done on women or on women-specific issues, doctors often treated them differently.
Even today, women are up to ten times more likely to have their symptoms explained away as being psychological or psychosomatic than men. Worryingly, women are 50 percent more likely to be misdiagnosed after a heart attack, and drugs designed for "everyone" are actually much less effective (for pain) or too effective (for sleeping) in women.
Are these differences real or imagined? And what can the history of female medicine teach us about where we are today?
A mutilated male
Aristotle is rightly considered one of the greatest minds of all time and is recognized as the founding father of many disciplines, including biology. He was one of the most rigorous and comprehensive scientists and field researchers the world had known. He categorized a large number of species based on a wide range of traits, such as movement, longevity, and sensory capacity. His views on women, then, stemmed from what he thought of as good, proper study. The problem is that he got pretty much all of it wrong.
According to Aristotle, during pregnancy, it was the man who, alone, contributed the all-important "form" of a fetus (that is, its defining nature and personality), whereas the woman provided only the matter (that is, the environment and sustenance to grow the fetus, which was provided by the menstrual blood).
From this, Aristotle extrapolated all sorts of dubious conclusions. He ventured that the man was superior, active, and dominant, and the woman inferior, passive, and submissive. As such, the woman's role was to nurture children, run a household, and be silent and obedient — political and cultural manifestations of dodgy biology. If women did not provide a child's form and nature, how important could they really be?
Given this passivity, Aristotle argued that the woman must be associated with other passive things, like being cold and slow. The man, being dynamic and energetic, must be hot and fast. From this, Aristotle concluded that any defects or problems in childbirth can only be due to the sluggishness of the female womb. Even the positive biological aspects of being female, such as greater longevity, were put down to this cold rigidity — a lack of metabolism and spirit. Most notorious of all, since Aristotle believed that female children were themselves the result of an incomplete and underdeveloped gestation, women were simply "mutilated males" whose mothers' cold wombs had overpowered the warm, vital, male sperm.
Aristotle can still be counted as a great mind, but when it came to women, his ideas have not aged well in just how far they negatively influenced what came after. Given that his works were seen as the authority well into the 16th century, he left quite the pernicious legacy.
A wandering womb
But, how much can we really blame Aristotle? Without the aid of modern scientific equipment, physicians and biologists were left to guess about female anatomy. Unfortunately, the damage was done, and Aristotle's ideas of a troublesome uterus became so mainstream that they led to one of the more bizarre ideas in medical history: the wandering womb.
The "wandering womb" is the idea that the womb is actually some kind of roaming parasite in the body, possibly even a separate organism. According to this theory, after a woman menstruates, her womb becomes hot and dry and so becomes extra mobile. It is transformed into a voracious hunter. The womb will dart from organ to organ, seeking to steal its moisture and other vital fluids. This parasitic behavior caused all sorts of (female only) illnesses.
If a woman had asthma, the womb was leeching the lungs. Stomach aches, it was in the gut. And if it attacked the heart (which the ancients thought was the source of our thoughts), then it would cause all manner of mental health issues. In fact, the Greek word for womb is "hystera," and so when we call someone (often a woman) hysterical, we are saying that their womb is causing mischief.
The "solutions" or "remedies" for a wandering womb were as strange as the theory. Since the womb was supposed to be attracted to sweet smells, placing flowers or perfumes around the vagina would "lure" it down. On the flip side, if you smoked noxious substances or ate disgusting foods, it would "repel" the womb away. By using all manner of smells, you could make the womb move wherever you wanted.
The oddest "remedy" — and most male-centric of all — is that, since the wandering womb was said to be caused by heat and dryness, a good solution would be male semen, which was thought of as cooling and wet. And so, the ancient and highly inaccurate myth was born that sex could cure a woman of her "hysteria."
A lingering problem
We live today with the legacy of this kind of thinking. Freud was much taken with the idea of "hysteria," and although he did accept that men could be subject to it as well, he believed it was overwhelmingly a female problem caused by female biology. The woman, for Freud, is mostly defined by her "sexual function." What Freud calls "normal femininity" (the preferred and best outcome) is defined by passivity. A woman's ideal development is one which moves from being active and "phallic" to passive and vaginal.
Nowadays, Freud and Aristotle's legacy lies in just how easily women are defined by their sexuality. Given that men and women, both, are equally dependent on their biology, it is curious how much more often women are reduced to theirs. The idea that women are more emotional or slaves to their hormones than men is still a depressingly familiar trope. It is an idea that goes back to the Greeks.
If we think biology is important to who we are (as it most certainly is), we ought to make sure that the biology is as good and accurate as it can be.
