Human Evolution: Welcome to the Friend Zone Now. Powered by – Now. Powered by Northrop Grumman.

When did humans learn to be friendly? Its an important question. While big brains helped humans outlast evolutionary competitors, such as the Neanderthals, smarts werent enough to secure our primacy at scale. By trading aggression for cooperation, early hominid groups were able to develop tactics that allowed them to both survive and thrive. But what prompted the formation of friendly frameworks in human evolution, and how did this friend zone help us zero in on beneficial human behavior?

According to Popular Science, friendliness and cooperation are the cornerstones of successful human evolution. Put simply, the friendliest were most fit for survival.

Heres why: While the popular interpretation of Darwins concept is to imagine fitness as describing the biggest, strongest and most aggressive individuals, survival of the fittest only refers to survival itself, both in the moment and by creating viable offspring. While aggression might offer greater access to food and mates, its also inherently stressful and dangerous. Aggressive humans could be injured or killed and, without the help of others, faced weakened immune systems from the stress of continually protecting their primary status. By working together, humans were able to accomplish more with less risk and theres now evidence to suggest that we self-domesticated our facial features over time by selecting mates that were more amicable than aggressive.

And while some of our earliest expressions, such as disgust or fear, were driven by optical needs disgust caused a narrowing of the eyes to improve focus while fear did the opposite to improve field of vision more intricate displays of cooperation or comfort were developed to help nurture the good side of our nature and encourage human beings to work in concert rather than in conflict.

The fundamental functions of friendliness start with facial expressions. Consider one of our most common cooperative markers: the smile. As Scientific American notes, many primate species consider bared teeth an aggressive gesture, especially if lips are curled and teeth are apart. Meanwhile, when lips are relaxed and teeth are together, submission is the likely supposition.

For humans, smiles likely started as a way to showcase mutual submission a willingness to work together and evolved into the ubiquitous expression we use today. Worth noting? Not all smiles are genuine. While babies naturally smile in response to pleasurable stimuli, adults can deliberately obfuscate true intentions by smiling to gain initial trust rather than taking any direct cooperative action.

So, when did humans learn to be friendly? In a BBC interview, anthropologist Chris Stringer of the Natural History Museum in London noted, As the last surviving species of humans on the planet, it is tempting to assume our modern faces sit at the tip of our evolutionary branch. This theory was originally supported by a supposedly common ancestor Homo heidelbergensis that lived 500,000 years ago and had a face midway between that of modern humans and those of Neanderthals. But a more recent discovery in Spain found a new species of hominin, called Homo antecessor, that lived more than 850,000 years ago and displayed facial construction much closer to that of modern humans. While theres no absolute certainty here, it seems that common human facial features may have existed far earlier than originally thought.

How does the world end? Not with a bang, but with a friend request.

Humans arent just interested in person-to-person friendliness. We also want to mimic the same function in robots. According to Brian Scassellati, professor of computer science, cognitive science and mechanical engineering and director of Yale Universitys Social Robotics Lab, Robots that engage with people are absolutely the future. Theres no question thats where robotics is moving. From caring contraptions that help children learn to winning workers that positively interact with other staff, mankind is committed to moving friendship forward even if it means hard-coding it into human analogues.

This speaks to the evolutionary impact of friendliness: the drive to cooperate rather than compete to advance the species as a whole. While individualism remains a sought-after quality for personal advancement, humans cant deny the power of positive interactions in large groups, even if those groups are partially artificial. In fact, theres a case to be made here that the robot revolution is our next evolutionary step. Sure, having super-strength or telekinetic powers would be fantastic, but these arent realistic outcomes. Humankinds greatest strength the development and deployment of new technologies offers the opportunity to make minds in our ideal image, friendship and all.

Small groups of early humans did well with aggressive leaders and insular behavior. But as big brains became the evolutionary exemplar, cooperation replaced conflict as the fittest function for ongoing survival. Faces formed the front lines of friendliness, fueling our drive for self-domestication that made working together even when we dont see eye-to-eye better than staying apart.

Nobody is apathetic this year: CT turnout at 50 percent by noon

Secretary of the State Denise Merrill said in a noontime news conference in West Hartford that turnout is already 50 percent, about equal to the states voting in the 2016 presidential race.

Twenty five percent are absentee ballots and the rest are people who crowded the states nearly 800 polling places since the predawn.

She said that the more than 2.3 million registered voters is a couple hundred thousand more than usual, and its the largest pool of electors the state has had heading into an election.

There are quite a few people here to vote, she said outside the Charter Oak International Academy. We are hearing all across the state a really, really large turnout.

So clearly people are voting and voting in big numbers. We have had very few problems that have been reported to us. I think its wonderful. I can throw away all those speeches I used to make about the apathy of voters because nobody is apathetic this year thats for sure.

Merrill said that the only problems that have been reported were a few power outages caused by the high winds that were quickly restored. In New London there was a problem with some voters getting the wrong ballots for their state House of Representative districts, and local officials were contacting voters to give them a chance to vote for the correct candidates.

I think these were absentee ballots that went out and there were two districts that got mixed up for a group of voters, but we can rectify, so were going to allow them to vote for all the offices except for the one thats in question, she said. And that would be two different state rep districts, and they are working right now on calling them all, finding out who they are and allowing them to vote on just that office, but their vote will count for everything else.

Asked to describe the turnout, she said: This is one of these deals where you have to figure out what human behavior is going to be. I think a lot of people asked for absentee ballots thinking, Well, Ill keep them and decide at the last minute if I want to go in person, because we did allow them that option. So it just shows, I guess, when you give people options, you dont know exactly which one they are going to take.

CORRECTION: A previous version of this story incorrectly stated 75 percent of voters in Connecticut had voted by noon, including the 25 percent who cast absentee ballot. The actual turnout was 50 percent, including the absentees.

University of Texas: Weather does not play significant role in COVID-19 spread – WWLP.com

CHICOPEE, Mass. (WWLP) Its something thats been studied since the beginning of the coronavirus pandemic: how the virus spreads inwarm, humid weather comparedto cold, dry conditions. There was a hope cases in the summer would plummet as the virus itself transmits more easily in cold and dry conditions,but cases continued to increase.

Now, a University of Texas at Austin study confirms that its human behavior, rather than the weather, thats overwhelmingly affecting the spread of COVID-19.

They studied counties, states, countries, and world regions.

At the county scale, the weathers relative importance was less than 3 percent.

This is in contrast to the top contributing factors to COVID-19 growth: taking trips and spending time away from home, as well as population and urban density.

Author Ted Scott invites readers to witness ‘The Making of a Master’ – GlobeNewswire

ROCKHAMPTON, Australia, Nov. 04, 2020 (GLOBE NEWSWIRE) -- A unique blend of timeless wisdom set in the entertaining context of an adventure story, The Making of a Master (published by Balboa Press AU) by Ted Scott narrates the moral and spiritual development of a young man who has to endure hardship and privation on the way to gaining wisdom and insight.

Qiang is a peasant farmers son and in his early years, he receives instruction from two Buddhist masters who come to him in different guises where he learns the basic tenets and practices of Buddhism. A great drought forces Qiangs parents to flee the farm with him and his young sister. On their journey Qiangs father, Chao, commits suicide, which leaves Qiang to guide his family. Fortunately the family is adopted by a regional governor, Ruan Xiu, on the basis that Qiang must serve the governor. The governor, a rather austere man aided by Buddhist adepts, sets Qiang a series of trials, which he finally completes to earn his own place as a master and the title Takygulpa Rinpoche.

The Making of a Master is a parable demonstrating in an accessible way what are essentially timeless truths. The book contains important philosophical content embedded in an action story revolving around well-developed characters.

When asked what he wants readers to take away from the story, Scott says, A clearer understanding of how to attain personal serenity and fulfilment.

Benson Show Gentle Rant: ‘How’d Things Ever Get This Crazy?’ – wkfr.com

The actual lyric is "She wonders how it ever got this crazy". It's a line from an old Eagles song (Lyin' Eyes). Maybe you thought it, too. You look around you and it's hard not to think "this is nuts."

There's also another gleaming platitude: "Those who don't pay attention to history are doomed to repeat it." I think of that a lot, too. The comforting thing about history is having the knowledge that it's been crazy like this plenty of times before in our past. Dirty elections are as old as this earth. It's the other stuff that's scary. Yes, we'll finally get it right eventually but that path is long and difficult. And what's even more troubling is we never seem to learn.

It doesn't matter whether it's the lessons taught in school about respect, or loving your fellow human - lessons taught in Sunday School, or even something as basic as The Golden Rule, it just seems like the system broken down. It's as if all the rules about decent human behavior went away. Between the pandemic and the election, suddenly it's been open season on friends, neighbors, strangers, anyone who doesn't think exactly like we do.

I could tell you what I think are some of the problems, but I'm not sure I'm right, and I'm even more sure I don't want the push back from everyone who thinks I'm wrong.

I'm old enough to remember the turbulent times of the late 1960's and early '70's. Everybody preached peace, love and brotherhood, getting along. Looking back, it's obvious those were nothing but empty words. It simply fooled some of us into thinking that things would get better. But we don't treat each other better. We are more polarized, more angry, more everything than ever before. And coupled with that, is that "I'm smarter than you" attitude that permeates.

Many people talk about the days after 9-11 when for a few short weeks we were all Americans, united. That was another mirage.

The point of all this wasn't to be depressing, even though it sure does sound like it. It's just the end of a long, depressing election season, coupled with a virus that is making a return appearance, maybe even more deadly than the first time.

I hope you can still hug and kiss your loved ones, that you are healthy and at least somewhat prosperous, and that you can enjoy your favorite bevy with friends who you like and who like you back, even if you don't agree on things. (I'm very lucky to be able to say yes to that.).

And Dear God, please save us from ourselves.

Election infection | News, Sports, Jobs – Lock Haven Express

Anyone who spends any amount of time online, and on social media in particular, cannot help but become bombarded by news stories, opinion posts, expert video breakdowns of whats really happening all around us.

So much of this shared virtual space seems dedicated to breaking down and reconstructing the political structure, to shared and re-shared monologues on the state of the nation, long chains of opinions and facts blurred together and passed again and again throughout the information network, facsimiles of facsimiles of facsimiles

I am reminded in all of this of a famous quote, one I found online, by president Abraham Lincoln: Dont believe everything you read on the internet.

Misinformation tactics, fake news on social media, political propaganda networks bent on pressuring the publics vision of reality consistently enough that they cant help but start conforming: these are not new subjects.

Get people to start using your words, and they will start sharing your vision, a strategy as old as political cynicism.

We probably dont need this reminder.

We certainly dont need to be told that social media is bursting with dubious content.

And yet

As has been variously reported and consistently suffered anecdotally, online misinformation spikes during election seasons.

Both internationally and domestically, bad faith actors fill the various media ecosystems with deceptive, self-serving informational junk food.

The kinds of stories and reports that push on the pleasure centers of our brain, exploiting our worst instincts and clogging the bloodstream of our democracy.

When given the option to consume easy media narratives that prove us right and them wrong and that taste like sweet retribution and savory political comeuppance, we often cant help ourselves; or rather, we dont know any better than to say no.

Online media literacy is the kind of skill that has only existed for several decades and has been widely important for even fewer.

The phrase fake news entered the public discourse sometime during the previous presidential election cycle, but instead of keying us into a heightened awareness of the way we consume media, it largely did the opposite, giving us permission to reject information we dont like as fake in favor of information we do.

Social media platforms like Facebook, meanwhile, have been designed specifically to cater to these impulses.

To a large extent, its not anyones fault that the majority of the population doesnt have this newly necessary skill of digital media literacy.

How could we?

Not that media literacy (i.e. the ability to evaluate the context and trustworthiness of things like news stories and published opinions) is something weve never cared about.

But the scale of the issue online takes proportions and evolves at rates that are difficult to fathom.

You cant blame someone for never being taught to swim, but in a world quickly filling with water, we will survive or perish depending on our ability to learn.

And thats just it, isnt it?

The existential threat of it all. This is an issue that affects the stability of our democracy, of our global ecosystem.

But perhaps most tangibly important, it threatens our local community.

One thing everyone can probably agree on is that the divisions between us and our neighbors are higher, more personal, more spiteful.

We feel like were all out to get each other, and we often are. Those political gotchas on Facebook, the pit in our stomach when someone we care about signals support for the other side, these small moments have the ability to consume entire days at a time.

We can turn away from the issue entirely, get off the social media grid, go offline.

This feels like an increasingly appealing solution, something Facebook has recently mimed with its decision to ban all political advertising on the platform up through the presidential election.

But this seems unlikely to be effective as a widespread solution. Its hard to change the course of history by appealing to the past.

The other option, then, is widespread learning.

Schools across the country have increasingly focused on these kinds of skills, and I can say from my own experience teaching college composition courses, digital media literacy has taken a central role.

Recent studies have indicated that younger age groups are less likely to share false or misleading news stories.

But in a world verging on ecological collapse, we ought to worry whether this improvement is happening quickly enough.

What else can be done to address this issue?

One helpful shortcut Ive found is to turn inward rather than outward, that is, to acknowledge the three proverbial fingers pointed back at us whenever we point out the shortcomings of others. In practice, this means recognizing when a political news story makes us feel good.

Its always a good literacy practice to learn to be especially skeptical of the ideas we most agree with.

This is how misinformation thrives and spreads, packaged and presented as exactly what we want to hear.

Were naturally less skeptical of things we agree with because, well, we already know were right.

And because we know were right, we tend not to worry if we might be wrong.

Instead of immediately sharing that news story, that monologue from the expert, repeating the opinion we heard on our favorite talk radio show, we might want to reflect on this reflex and realize just how little thought we put into the matter.

It usually isnt all that much.

We come to see how much more were focused on winning the argument than getting to the truth or resolving the issue at hand.

We realize the world is a bit more complicated than wed like it to be, and though that can be scary and paralyzing, we ought to know and try better.

It goes without saying that, though digital media literacy is an issue within contemporary politics, it is not a political issue.

This is a human behavior issue, and as we are all human, this is an issue we all face.

It is wrapped up in instincts we cannot eliminate but can at least monitor and keep in check.

Personal awareness of our media habits might seem like a small solution in the face of such large, existential problems, but its one of the few ways to make a direct and individual impact.

On its own, it probably isnt enough, but its something.

Amplifire Secures Patent for Analytics Regarding the Confidence of Learners – BioSpace

BOULDER, Colo., Nov. 2, 2020 /PRNewswire/ -- Amplifire, an eLearning company, announced today the award of an additional patent by the United States Patent Office. Amplifire holds patents issued in the US, EU, Australia, Canada, Japan, South Korea, and other countries and jurisdictions worldwide. The new patent is titled Display and Report Generation Platform for Testing Results.

"Our customers view knowledge as a strategic way to compete."

The new patent, US Patent No. 10,803,765, is directed to aspects of Amplifire's learning platform, which includes unique Answer Key and Reporting Dashboard features. The Answer Key allows learners to signify both their confidence and answer choice in one click, which fosters greater metacognition. The Reporting Dashboard builds visual analytics displaying a learner's misinformation, uncertainty, and struggle in bar charts and heatmaps. Search and sorting features allow managers or instructors to see their organization's knowledge at any scale, from individual to team to division, and across the enterprise.

Confidence measures shown in the reporting dashboard are essential because confidence is the precursor to human behavior. It appears as internal thoughts such as, "I've got this," or, "I haven't a clue what to do." The Amplifire dashboard reports and sorts using the confidence a learner displayed when they answered questions in the assessment phase of learning and subsequent refreshers. The most dangerous form of confidence occurs when a learner is sure but incorrect, referred to as confidently held misinformation, driving them towards a mistake.

The ability to see how confidence is bound to knowledge gives learning officers, administrators, and instructors a window into the risk of future mistakes in their workforce. Visualizing human fallibilities such as misinformation, uncertainty, and struggle lends unprecedented guidance to managers and instructors. For the first time, they can see the people who improve in the platform, where pockets of risk lie, and who needs at-the-elbow help.

Amplifire CEO, Bob Burgin, noted, "We are proud that the US Patent Office noticed our reporting dashboard's unique features and awarded our efforts with a patent. Amplifire's product development team regularly thinks up new ways to help people overcome the knowledge problems inherent in the human condition. Our customers view knowledge as a way to compete. They understand it's strategically in their interest to help their people reach new levels of performance."

About AmplifireWith over 2.4 billion learner interactions, Amplifire (www.amplifire.com) is the leading adaptive learning platform built from discoveries in brain science that help learners master information faster, retain knowledge longer, and perform their jobs better. It detects and corrects the knowledge gaps and misinformation that exist in the minds of all humans so they can better attain their real potential. Healthcare, education, and Fortune 500 companies use Amplifire's patented learning algorithms, analytics, and diagnostics to drive exceptional outcomes with a significant return on their investment.

The future of grizzlies comes down to the choices we make – Explore Big Sky

By Todd Wilkinson EBS Environmental Columnist

The confirmed sighting in October of a grizzly in the lower reaches of Bear Canyon just southeast of Bozeman is yet another reminder of how close the big bruins are now living near peoplein this case within the exurban outskirts of the fastest-growing micropolitan city in America.

Not only is that considered extraordinary for Westerners entering the third decade of this new millennium, but such a happening was believed unthinkable 45 years ago when the Greater Yellowstone population of grizzlies was given federal protection as a threatened species under the Endangered Species Act.

For decades, the only grizzlies that came close to busy four-lane Interstate 90 connecting Bozeman with Livingston over Bozeman Pass were captive bears residing at a roadside zoo.

But in mid-October, bow hunter Dash Rodman was sitting in a tree when he saw what he believed to be a grizzly strolling beneath his perch high above the ground along the riparian corridor of Bear Creek.Later, Bear Canyon resident Renee Thill posted a short video of the bruin by Rodman and a photo of a paw print in the snow.

Called to investigate, Kevin Frey, a longtime bear management specialist with Montana Fish, Wildlife and Parks, paid a visit to Bear Canyon on Sunday Oct. 18, finding a strand of ursid hair on a fence but no tracks in the mud. Still, upon reviewing Rodmans film, he said,Yes, definitely a grizzly; it looked to be a subadult. The thing is that if the archery hunter hadnt been there when the bear passed through, the world probably would never have known the bear had come down the creek corridor and then probably went back up into the mountains.

While not surprising to Frey, the sighting created a sensation of speculation on social media. Bear Canyon is a drainage with a road that dead ends and along the way are homes and two busy trailheads leading across state lands and the Custer-Gallatin National Forest. Indeed, this place-name lives up to its moniker.

Seeing a grizzly only a few miles, as the crow flies, from Bozemans Main Street is a big deal even for old-timers. But Frey says grizzlies, in fact, have been wandering the northern front face of the Gallatin Range where it meets the Gallatin Valley for a few years and most people are unaware.

Many bruin navigations have largely happened without incident because the grizzlies have done a good job of avoiding people, Frey says, though he is concerned that close and potentially dangerous encounters could occur as more outdoor recreationists pour into the Gallatins, venturing off established trails and increasing the likelihood of bumping into a bear.

As far as bears go, I call it a waltz, Frey said. They are dancing in a forest full of obstacles and people sometimes behaving like chickens with their heads cut off. The bears are doing their best to avoid us. They are not seeking trouble, Frey says, noting that its human behavior that will determine if bears have a future there.

Frey is amazed at how growth in the human population of Bozeman and greater Gallatin Valley is quickly affecting (negatively) how wildlife are using landscapes and how they mightor might notmove through them in the future.

Frey says theres no doubt in his mind that the Greater Yellowstone grizzly population is healthy and has met criteria that determines whether it is biologically recovered. He believes the population can be delisted.

From a population that dipped to around 130 grizzlies or fewer in this entire massive ecosystem, equal in size to New England, and with bears mostly clustered 50 years ago only in Yellowstone Park, the regional population today is more than 700. Recovery has happened only because humans changed their lethal behavior and made habitat protection a priority.

While indeed bears are showing up in places where they havent been in a century or more, theyre paradoxically facing shrinking and more fragmented habitat from more development and rises in recreation users, he said.

Bear Canyon represents kind of a microcosm for pondering the challenges of human-wildlife coexistence in Greater Yellowstone, he notes, and thinking about what wildnessis. Lots of weedy, highly adaptable species, such as white-tailed deer, coyotes and maybe half-tamed elk and moose can navigate the wildland-urban interface, but having grizzlies is a test of human smarts and responsibility.

Given the inundation of COVID-19 refugees and transplants occurring in Bozeman, as expressed in a recentWashington Poststory, its clear that many in the drove, drawn to what they perceive to be paradise, have little wherewithal when it comes to coexisting with a rare caliber of wildness far beyond anything they had previously known.

Irrational fear about bears and other carnivores like mountain lions is what historically led to a lack of human tolerance for those species and eventually left them rubbed out of the landscape. Can they learn to be bear wise? Will even local Bozemanians and residents of Big Sky realize the miracle that it is to have grizzlies present in the citys public lands backyard? Time will tell, Frey says.

Todd Wilkinson is the founder of Bozeman-basedMountain Journal and is a correspondent for National Geographic. Hes also the author ofthe book Grizzlies of Pilgrim Creek, featuring photography by Thomas D. Mangelsen,about famous Jackson Hole grizzly bear 399.

Immune cells are responding to Covid six months after infection, study finds – CNBC

A medical professional applies a nasal swab during testing at the Orange County Health Services Covid-19 drive-thru site at Barnett Park in Orlando, Fla., Thursday, October 29, 2020.

Cellular, or "T-cell," immunity against Covid-19 is likely to be present within most adults six months after primary infection, a new study said.

Research by the U.K. Coronavirus Immunology Consortium (UK-CIC), Public Health England and Manchester University NHS Foundation Trust has found "robust T-cell responses" to the coronavirus six months after infection.

T-cells are a part of our immune system that attack cells which have been infected with a virus or other kind of pathogen and they help other antibody-producing cells in the immune system. Scientists have been investigating T-cell responses to the coronavirus to see how lasting any immune response might be in individuals who have caught, and recovered from, Covid-19.

This latest study looked at 100 individuals who had tested positive for the coronavirus in March and April of 2020 but had not been hospitalized with the virus. All 100 individuals had experienced either mild or moderate symptoms or were asymptomatic (56 versus 44 people), the study noted.

Serum samples were collected monthly to measure antibody levels, and blood samples were taken after six months to assess the cellular (T-cell) response to the virus.

A range of analyses were carried out to assess different aspects of the T-cell response including the magnitude of response and the response to different proteins from the virus, the study noted.

"T-cell responses were present in all individuals at six months after SARS-CoV-2 infection," it said, indicating "that a robust cellular memory against the virus persists for at least six months."

The study found, however, that "the size of T-cell response differed between individuals, being considerably (50%) higher in people who had experienced symptomatic disease at the time of infection six months previously." The study has not yet been published in a medical journal or peer-reviewed.

The findings could improve our understanding of how immunity to the coronavirus works, as well as informing future vaccine strategies, the study authored by Dr. Shamez Ladhani, a consultant epidemiologist at Public Health England noted.

"Cellular immunity is a complex but potentially very significant piece of the Covid-19 puzzle, and it's important that more research be done in this area. However, early results show that T-cell responses may outlast the initial antibody response, which could have a significant impact on Covid vaccine development and immunity research."

The study notes that further research is now needed to assess whether this immune response is maintained over the longer term and to better understand how the strength of the cellular immune response corresponds to the likelihood of reinfection.

Professor Paul Moss, the U.K. Coronavirus Immunology Consortium lead from the University of Birmingham, said that further work was needed to find out if people who were symptomatic with Covid-19 were safer from future reinfection.

"Interestingly, we found that cellular immunity is stronger at this time point in those people who had symptomatic infection compared with asymptomatic cases. We now need more research to find out if symptomatic individuals are better protected against reinfection in the future."
