NSF grant funds research to study nature-based solutions for river restoration – Penn State News

Posted: January 18, 2020 at 10:11 am

UNIVERSITY PARK, Pa. As communities look to restore their waterways after centuries of human alteration, many are turning to nature for inspiration.

River restoration projects utilizing nature-based solutions, like the Big Spring Creek restoration project in Cumberland County, Pennsylvania, revitalize their ecosystems by reintroducing natural materials like wood and debris into their design. These materials over time often amass into complex, porous structures that offer many ecological benefits but are not well understood, according to Xiaofeng Liu, associate professor of civil engineering and co-hire of the Institute of Computational and Data Sciences at Penn State.

Thanks to a $297,791 grant from the National Science Foundation, Liu will examine the nature-based solution of engineered log jams to quantitively describe the flow and sediment dynamics around these systems.

Xiaofeng Liu, associate professor of civil engineering

These are expensive projects, but theres not too much of a scientific understanding of what really is going on, Liu said. How does the water move around the in-stream structures? How does it carry solute and sediment?

In contrast to restoration projects that use concrete and steel, water and sediment are able to flow through the pores in the nature-mimicking structure, creating unique turbulent flow patterns.

The porosity creates more complexity and richness in the flow features, Liu said. Water can go through them and around them. This complex flow field is important for the functionality and longevity of the structure.

As these flow patterns develop, sediment is transported and sometimes filtered by the wood and debris. This sediment movement around the log jam can also result in scour holes that can become habitats and shelters for fish, a desirable characteristic of nature-based solutions. However, Liu noted, these holes develop differently than they would around traditional impervious structures, such as bridge piers, and can have an effect on the longevity of the structure.

For engineers looking to install an engineered log jam, the lack of fundamental understanding of these complex flow patterns means relying on educated guess. Formulas that currently exist to predict scour hole size and depth do not account for porosity.

Its a lot of trial and error at this stage right now, Liu said.

Based on preliminary results, Liu developed his own formula using porosity as a parameter to help predict scour hole size for nature-based solutions. He will test this by developing a high-fidelity 3D model to simulate the flow and sediment dynamics in a river containing an engineered log jam.

Mathematically resolving all of the geometric details found in an engineered log jam requires a lot of computing power, so Liu will rely on the ICS-ACI, Penn States high-performance research cloud, to run the simulations.

The mathematical equations in the model are just the descriptions of the physical processes in this problem, Liu said. Flow carries the sediment and creates a hole. When holes are enlarged, water has more space to go. Our model describes this co-evolution with the presence of a complex restoration structure.

Liu will also run physical experiments in a 15-meter flume, an artificial water channel in the Penn State Hydraulics Laboratory, using scaled-down engineered log jam models. After each experiment, he will drain the flume and use a laser to scan the bed. The results of the flume experiments will then be cross-referenced with the computational model and with field measurements to validate results.

If Liu succeeds and is able to establish a fundamental understanding of the physical processes occurring around these structures, future research will then be able to link that to ecological processes, which should give scientists a better idea of how well these solutions are achieving their sustainability goals.

Thats the final goal, Liu said. Hopefully, with the introduction of nature-based solutions, nature can start to re-establish itself. When nature is working, you dont need too much human intervention.

How we deduced that our ancestors liked roast vegetables too – The Conversation Africa

Posted: at 10:11 am

Archaeological work at the Border Cave site has revealed the earliest evidence for cooked root vegetables. Border Cave lies between South Africa and eSwatini and has a remarkable record of human habitation.

Hot, roasted root vegetables are comfort food, and a plateful of carbohydrate is both satisfying and nutritious. Archaeologists have found that our ancestors thought so, too. A team working at the site has discovered and documented the remains of starchy underground plant stems (called rhizomes) cooked 170,000 years ago.

Border Caves roasted rhizomes were identified as Hypoxis angustifolia (yellow stars). This was done by comparing their shape and internal anatomy to those of modern rhizomes which today grow in countries along the eastern flank of Africa. The distribution extends much further too, for example into Yemen.

If, as seems likely, Hypoxis had a similar distribution in the past, it would have provided a secure staple food for people travelling within and out of Africa.

Our findings suggest that the food was transported to the cave and then cooked. The food could easily have been consumed directly in the field by the collectors, but our findings suggest this wasnt the case, adding extra information about social behaviour and sharing and a glimpse into ancient communal behaviour 170,000 years ago. Food was the focus for satisfying physical and social hunger.

Hypoxis angustifolia plants are gregarious so many can be harvested at once. Wooden digging sticks or sharpened bones may have been used to dig rhizomes from the ground.

The food was carried home to the cave, perhaps as a hide-wrapped parcel or a simple bunch tied with leaves.

Wood was also collected for the cooking fire that probably burned to small coals and hot ash before the rhizomes were added directly to the ashes for roasting. Some South Africans are familiar with this cooking technique: as children we made askoek (ash cakes) directly on coals and tapped them on rocks to dislodge the ash before garnishing our culinary treasures with apricot jam.

Some of the thumb-sized Border Cave rhizomes were lost in the ashes where they were burned and thus preserved for archaeologists. We know that they were burned while still fresh and green because the charred rhizomes have split surfaces. This was caused by shrinkage when moisture was rapidly expelled. Many starchy root vegetables can be eaten raw, but their nutritional content is much greater when cooked (the human gut can then access the glucose better and absorb much more of it).

Cooking made Hypoxis rhizomes easy to peel, and rendered them digestible by releasing glucose and breaking down the fibre. Such treatment was particularly important for the aged members of the group and small children that might otherwise have had difficulty chewing the rhizomes.

The Border Cave occupants were modern humans (Homo sapiens) with the same nutritional needs as people today. To enable our large brains to function we need to consume about 100g of carbohydrate per day. Hypoxis rhizomes may have fulfilled that need in the past.

We know, too, that Border Cave dwellers also ate meat because we have recovered the cooked bones of wild animals that were eaten in the cave. In Africa, game meat is lean, especially in the dry season when animals lose weight. Lean meat protein cannot be metabolised by humans in the absence of either carbohydrates or fat.

The addition of some carbohydrate to their diet would then have enabled early humans to process protein effectively. A balanced, healthy diet with a combination of cooked carbohydrate and protein the real palaeo-diet - increased human fitness and longevity.

We discovered the first of the rhizomes in 2016 while digging in Border Caves ashy sediments. The sediments date between 170,000 and 100,000 years ago.

In total, 55 whole charred rhizomes were recovered, all from the same species. We worked together in the field over a period of four years, collecting modern plants with rhizomes so that we could compare these with the Border Cave ones in order to identify them.

With a permit from local wildlife authorities, we surveyed the Lebombo Mountain hillside near the cave for interesting plants with appropriate rhizomes. When a plant could not immediately be identified it was planted in a vegetable garden to await flowering. When each plant was securely identified, its rhizome was charred, examined microscopically, and compared with Border Cave specimens.

Eventually patience was rewarded, and a combination of morphological and anatomical evidence showed that the Border Cave rhizome was a Hypoxis.

‘Passion, love’ – Nadal’s tips after defying injury to reach third decade on top – Yahoo News Australia

Posted: at 10:11 am

Rafael Nadal said passion and positivity had helped him reach an unprecedented third decade ranked world number one, after defying the ravages of injury and the critics who said his all-action game was too tough on his body.

Despite a steady stream of foot, knee, back, arm, hand and wrist injury setbacks, the 33-year-old has returned time and again to become the only player to top the rankings in three different decades.

"I can't say I have been lucky with injuries, because I have not," the Spaniard said on Saturday, when asked about his longevity in the game.

"But there is no secret, no? There is only about passion, about love for the game, and about being able to stay positive in the tough moments."

Nadal's physical, uncompromising approach is often contrasted with his great rival Roger Federer, who appears more effortless on court and -- after far fewer injuries -- is still going strong at 38.

But the fighting qualities that have taken Nadal to 19 Grand Slam titles on court have often been evident off it, as he was repeatedly able to recover from injury and return to the top.

"It's true that I went through some tough situations during all my career. But I was able to always, with probably the positive attitude and with the right people around -- they were the key -- I was able to find a way to keep going, no?" he said.

"It's difficult for me to imagine because for my style of game, as a lot of people said, my career should be little bit shorter. But here we are. Happy for that.

"Even for me is a big surprise to be where I am at my age."

Spain's Rafael Nadal said even he was surprised at his longevity in the game

Elon Musk is still thinking big with SpaceX’s Starship Mars-colonizing rocket. Really big. – Space.com

Posted: at 10:00 am

Surprise, surprise: Elon Musk is thinking big.

SpaceX's billionaire founder and CEO outlined some ambitious goals for the company's Starship Mars-colonization system during a flurry of Twitter posts on Thursday (Jan. 16).

The Starship architecture consists of a big spaceship called Starship, which Musk has said will be capable of carrying up to 100 people, and a giant rocket named Super Heavy. Both of these vehicles will be reusable; indeed, rapid and frequent reuse is key to Musk's overall vision, which involves cutting the cost of spaceflight enough to make Mars colonization and other bold exploration feats economically feasible.

Related: SpaceX's Starship and Super Heavy Rocket in Pictures

And "frequent reuse" is a bit of an understatement, it would seem. In one of Thursday's tweets, for example, Musk wrote that the eventual goal is to launch each Starship vehicle three times per day on average. Each Starship will be able to carry about 100 tons of payload to orbit, so, at that flight rate, every vehicle would loft about 100,000 tons annually, he explained.

And there won't be just one Starship far from it, if everything goes according to Musk's plan.

"Building 100 Starships/year gets to 1000 in 10 years or 100 megatons/year or maybe around 100k people per Earth-Mars orbital sync," Musk wrote in another Thursday tweet.

"Orbital sync" refers to an alignment of the two planets that's favorable for interplanetary travel, which comes along just once every 26 months. So, Musk envisions huge fleets of Starships departing during these windows.

"Loading the Mars fleet into Earth orbit, then 1000 ships depart over ~30 days every 26 months. Battlestar Galactica " he wrote in another tweet. (And Musk wants each Starship to keep flying for a while. In yet another tweet, he said SpaceX is aiming for an operational life of 20 to 30 years for each vehicle.)

Musk wants all of this activity to lead to the establishment of a sustainable settlement on the Red Planet. This goal making humanity a multiplanet species is close to the entrepreneur's heart. He has repeatedly stressed that it's why he founded SpaceX back in 2002, and why he has been amassing wealth for the past few decades.

Back in mid-2017, Musk said that the Starship architecture (which was then called the Interplanetary Transport System) could potentially allow a million-person city to rise on Mars within 50 to 100 years. He's still working toward such an ambitious timeline an even more ambitious one, in fact. On Thursday, one of Musk's Twitter followersasked, "So a million people [on Mars] by 2050?" The billionaire responded simply: "Yes."

Super Heavy won't make the trip to Mars, by the way; the huge rocket is needed just to get the Starship vehicle off Earth. The passenger spacecraft will be able to launch itself off the moon and Mars, both of which are much smaller than our planet and are therefore much easier to escape.

SpaceX is currently building its first Starship orbital vehicle, called the SN1, at the company's South Texas facilities. Also on Thursday, Musk tweeted a photo of technicians working on the SN1's nose cone and liquid-oxygen header tank.

Starship could get up and running soon. SpaceX representatives have said the first operational missions of the vehicle, which will likely loft communications satellites, could come as early as 2021. And there's already one crewed mission on Starship's manifest a round-the-moon voyage booked by Japanese billionaire Yusaku Maezawa, which is targeted for 2023.

Local student selected as semifinalist in competition to name Mars 2020 rover – KRDO

Posted: at 10:00 am

News

MONUMENT, Colo. -- A local high school student has been selected as a semifinalist in NASA's "Name the Rover" competition, which aims to find an official name for the Mars 2020 rover.

Kaitlyn Ketchell, a 10th grader at Palmer Ridge High School in Monument, is one of 155 students across the U.S. chosen as semifinalists in the essay contest.

Ketchell has proposed the name "Tenacity."

"Tenacity would be a fitting name for the rover, as Mars is a very barren planet, and yet we are determined to try and colonize it," Ketchell wrote in her essay submission. "Along with Curiosity, the two rovers could represent some of the best aspects of humanity, inspiring future generations to explore for explorations sake."

Her submission was selected as Colorado's winner in the high school category, according to a press release from Battelle, one of the organizations chosen to conduct the contest.

The currently unnamed rover will search for signs of past microbial life on Mars, characterize the planet's climate and geology, collect samples for future return to Earth, and pave the way for human exploration of the planet, according to the release. The Mars 2020 rover is targeted for aJuly 2020launch and is expected to touch down on Mars inFebruary 2021.

Heres what all the movies set in 2020 predicted this year would be like – Digital Trends

Posted: at 10:00 am

Life in the 2020s might be new to you and me, but its far from fresh territory for movies and TV. Once cast as a far-off future (or, at least, moderately far future) setting for speculative sci-fi movies, real-world calendars have finally caught up.

What did screenwriters think the world would be facing in the year 2020? Whats the science to accompany the fiction? Lets take a look:

In the movie: Directed by Scarface director Brian DePalma, Mission to Mars depicts an ill-fated mission to Mars, set in the year 2020. Needless to say, it doesnt go according to plan. Not for the astronauts in the story or, probably, for DePalma. At least commercially, his movies have largely failed to launch since this abortive voyage.

In real life: NASA will indeed launch another mission to Mars in 2020, although it wont have any people on board. Instead, the mission will seek signs of habitable past conditions on Mars, including microbial life. As far as the possibility of a crewed mission to Mars is concerned, our faith rests with Elon Musk who has been talking about just such a mission for years.

In the movie: By 2020, human boxers have been replaced by robots. Washed-up former boxer Hugh Jackman has been replaced as part of this automation wave. He teams up with his estranged son to build and train a kickass new fighting robot that can finally be the champion he never was. Imagine Rocky if it was made by the team at Boston Dynamics.

In real life: A growing number of people are concerned about the impact automation is going to have on the job market. Thats particularly true of physical jobs. There have been some impressive advances in robots that can emulate the movements of their human controllers, too.Unfortunately, the most concerted attempt to make fighting robots a real thing the company MegaBots collapsed in 2019. Its prototype battling bot, which cost $2.5 million to build, was auctioned off on eBay. Theres no evidence to suggest that it was bought by Hugh Jackman.

In the movie: The majority of Europe has been overtaken by an alien invasion force. A global military alliance called the United Defense Force (UDF) is created to fight the alien threat. It uses newly developed mech suits to give soldiers augmented fighting capabilities.

In real life: No alien forces arriving by comet, although Brexit has proven a bit disruptive in Europe. The mech suits were a good shout, though.Sarcos Robotics is one of several companies working to make augmented exosuits a reality.In 2020, it will ship the first alpha units of its Guardian XO powered exosuit to initial customers, including the U.S. military. These suits will enable wearers to carry out impressive feats of strength, such as lifting and manipulating 200-pound objects without breaking a sweat.

In the show: The Matt Smith-era Doctor and companions Amy Pond and Rory Wiliams land in Wales. A drilling operation is taking place, which winds up disturbing a civilization of reptile creatures called Silurians who live under the surface. As the former rulers of Earth, they decide they want their planet back. Hijinks ensue.

In real life: Theres plenty of digging into the Earths surface for a variety of reasons. No lizard master race as of yet. Still, theyve got the best part of twelve months to decide to show themselves if they want to prove this storyline accurate.

In the movie: What is it with writers assuming that 2020 would be the year in which the U.K. suffers the wrath of dormant creatures awakened during mining expeditions? In Reign of Fire, Christian Bale, Matthew McConaughey, and Gerard Butler cash checks as survivors of a dragon-related apocalypse. (Confusingly, the movie previews give the date as 2084, but the movie itself describes it as being 2020.) Dragons, it turns out, helped kill the dinosaurs. This is told to us through newspaper clippings.

In real life: Dragons arent wreaking havoc on humanity. Newspapers arent doing too well, either. Seeing as Reign of Fire is set in a post-apocalyptic world, theres not much to extrapolate here in terms of accurately predicting the future. It did, admittedly, nail how crucial Bale, McConaughey, and (to a slightly lesser extent) Butler would be to humanity, though.

In the movie: In the 2020 imagined in this 1965 Roger Corman cheapie (freely adapted from the Soviet science fiction movie Planeta Bur), Earth has colonized the Moon. Astronauts travel to Venus, discovering a prehistoric world full of dinosaurs, monstrous plants, and assorted dodgy special effects.

In real life: Half a century after humans landed on the Moon, we have yet to colonize Earths lunar satellite. We do, however, have another mission (or several) planned to land on it. And plans to use the Moon as a possible DNA data bank to keep a record of all civilization.The last NASA mission dedicated to Venus was the Magellan probe, launched in 1990. Over four years, it mapped 98% of the planets surface. Alas, no dinosaurs!

In the movie: Okay, I admit it: Akira isnt actually set in 2020. Its set in 2019, but Im including it here because of the reference to the lead-up to the 2020 Olympics. Impressively, the movie accurately predicted that Tokyo would be the site of that years Olympic Games. The stadium constructed for the event figures into the plot as a key location for Akiras climax.

In real life: Well, it got the Olympics bit impressively right. Fortunately, World War III hasnt broken out although not always for lack of trying. The futuristic aesthetic of modern Tokyo with its cyberpunk trappings and disaffected teens is pretty much spot-on.Disappointing lack of oversized stuffed toys and marauding motorcycle gangs, though.

Amos Is Enough Reason to Finally Watch The Expanse – The Ringer

Posted: at 10:00 am

I want you to imagine your personal favorite TV character delivering the line I havent felt fear since I was 5 years old. Don Draper saying it, Logan Roy saying it, John Luther saying it, Jim Hopper saying it. (Were probably talking about a dude here, given the lines wanton dudeliness, but sure, imagine, like, Villanelle or even Fleabag saying it.)

So: I havent felt fear since I was 5 years old. Howd that go for you? Not well, yes? Did your personal favorite TV character perhaps sound a wee bit unconvincing? Brotastic? Ridiculous? Embarrassed? Embarrassing? Who among us, even in these glorious streaming-era boom times, can invest those words with the precise deadpan-badass tone that will hint at tragedy without lapsing into disastrous unintentional comedy?

One among us. This guy.

Amos Burton is a character on The Expanse. Wait. Get back here. Yes, those of you who do not watch The Expanse (yet) likely know it as that hardcore science-fiction show, often reductively described as Game of Thrones in space, that at least three of your friends are furious with you for not watching. Its great, and youre missing out, and youre sick of being told youre missing out, and thats understandable. Please do not hold this against Amos.

Industry-wise, The Expanse is also known as the ultra-rare canceled series that irritating diehard fans actually saved. It premiered in late 2015 on Syfy, got decent ratings and oft-rapturous reviews, but found itself unjustly scrapped in 2018 after three seasons for convoluted business reasons. (Syfy made money only if you watched the show live, basically.) Enter Jeff Bezos, savior of the 23rd-century working (space)man, who soon personally announced that Amazon Prime had swooped in to rescue the show. He has his reasons.

Season 4 premiered, in full, on Amazon in mid-December. It rules. Youre still missing out. Partly this is due to its staggering scope, its rad space-torpedo special effects, its rich-text sociopolitical intrigue. But more importantly, its down to the very human (usually) and very relatable frailty (occasionally) of its characters. As with, sure, Game of Thrones, a fantastical extended universe is only as fantastic as the expertly drawn people (or whatever) moving through it. Heres a Season 2 scene when Amos basically punches a guy from Syfy straight to Amazon Prime.

Based on a nine-book series (described as a really kickass space opera by George R. R. Martin himself) by two writers working under the pen name James S.A. Corey, The Expanse is a dense, sprawling, wildly ambitious feat of galaxy-building so sprawling I am loathe to explain it in much detail, because Ill probably just fuck it up. So: In the 23rd century, conflict is inevitable between Earth (ravaged by climate change but still dominant), Mars (colonized by humans and increasingly militaristic), and Belters, those working-class and oft-downtrodden denizens of the asteroid belt connecting Mars and Earth to the outer planets. Also, a mysterious alien entity known as the protomolecule is a constant threat to either wipe out humanity or open an extra-mysterious Ring Door to new galaxies full of uninhabited worlds, or both.

So: A ragtag crew of charismatic do-gooders spanning Earth, Mars, and the Belt flies around on a spaceship called the Rocinante, getting into rad-space-torpedo-type adventures. Season 4 mostly involves one of those new galaxies, and an Earth vs. Belters proxy war with heavy settler-refugee overtones. The plot is fine; the plot is impressively complex. But at this point the whole point is to hang around with your old friends, be they Rocinante captain and reluctant-hero type Jim Holden (Steven Strait), or Belter ex-freedom-fighter Naomi Nagata (Dominique Tipper), or hotshot Martian pilot and quasi Texan Alex Kamal (Cas Anvar), or ferocious Earth politician Chrisjen Avasarala (Shohreh Aghdashloo), or idealistic Martian ex-soldier Bobbie Draper (Frankie Adams, and no, her character is not a Mad Men crossover attempt).

The Expanse, in short, has no shortage of Favorite Character materialsee also Cara Gee and David Strathairn (!!) as Belter leaders with splendidly intense accentsthough this season, while excellent overall, is tough on many longtime favorites, whether its Holden (too mopey) or Avasarala (forced to swear constantly to amuse the internet) or Draper (isolated in a subplot that is literally Mars kinda sucks now). Amos, by contrast, gets a way better deal this season, and makes the most of it. I love him very much, especially when hes scaring the bejesus out of everyone.

As played by Wes Chatham, an affable Georgia native and Hunger Games veteran whose young sons have amazing hair, Amos is an expert spaceship mechanic and laconic tough guy whose biceps are larger than many other characters heads. He is from Earth. Specifically, Baltimore. (There is something so exotic and soothing about the way anyone on this interstellar-warfare show says Baltimore.) He has, due to a mercifully vaguely described traumatic childhood, an inflexible moral code combined with a near-complete lack of empathy. (Hence the not feeling fear since he was 5 years old.) Hes working on it, and softening somewhat; he represents The Expanses most troubling and engrossing multiseason character arc, a hard-punching murder robot slowly learning to feel. He is ferociously loyal but hilariously awkward, homicidal but terrifyingly pragmatic about it.

Thats where the deadpan part of the badassness comes in. His love interest in Season 4, a fellow Earth-born soldier type named Chandra Wei (Jess Salgueiro), is technically on the opposing side of this seasons specific conflict, and threatens to shoot Amos if it ever comes to it, a threat he takes, as he takes most things, in disturbing stride.

That is the face everyone makes when talking to Amos. From the start he has capably filled both the Tough Guy role and, somehow, the Comic Relief role, his constant threats of violence so dispassionate they dont quite register as threats. Im not gonna lie to you: Either way this plays out, youre dead. In case I have to kill you, I just wanted to say thanks. That sort of thing. Youre not that guy, he counsels a mild-mannered botanist he befriends in Season 2, convincing him not to shoot the extremely evil guy hes about to shoot. The botanist shakily lowers his gun and walks off, his innocence intact. The extremely evil guy is relieved. And then, from Amos, the sorta-punch-line: I am that guy.

Which is hilarious, in a sci-fi-badass sort of way. Another great thing about The Expanse is that something legitimately exciting is always happening. Rather than your typical takes-six-episodes-to-get-going enterprise, the show leaps from tense standoff to tense standoff, and theres Amos always in the thick of it, gun trained on somebody and somebody elses gun trained on him, delivering the ridiculously hard-boiled dialogue such a situation demands. You got a clean shot, back of the headtake it if you need it. Imagine your personal favorite TV character saying that, even. Its not that Chatham ever winks, or quips, or mugs for the camera to rebuke you for taking this at all seriously. What makes him comic is that theres no real relief.

As myriad YouTube tributes have proved, you can frame Amos as an exclusively ultra-dark character, with grim hints of a child-sex-trafficking past neither the show nor the books have delved into long enough or deep enough to feel exploitative. (If Season 5 follows the books, well follow him back to Baltimore, where he will grapple with what Chatham has described as his characters mother-figure-plus-lover situation that he had. It can get a little weird.) There is something entirely inappropriate about Amos, as both a living human and a narrative device. One of his funniest early moments, in which he describes Naomi to Holden (who is Naomis boyfriend) as like a sister to me, concludes as follows:

Theres that look again. As The Expanse has deepened and widened, Amos has gotten his philosophical moments, his little speeches, from Everyone leaves unfinished businessthats what dying is to The way I see it, theres only three kinds of people in this world: bad ones, ones you follow, and ones you need to protect. That Chatham can dole out these nuggets of wisdom while holding a machine gun is extra impressive. But he was born to Kick Ass and Be Problematic. If this were the sort of show that inspired lots of hand-wringing think pieces, the dramatic conclusion of the Amos-Wei romance would inspire a whole bunch of them: Its ugly and squirmy and also, as always, furiously logical and moral, according to his uncomfortably vivid and distinct brand of morality. Here is our last look at Amos in Season 4.

Yikes. Perfect. What a monster. What a gent. Then he punches a guy (presumably, but come on) to death. It makes sense if you watch the show. Its the perfect Amos moment, really, if you watch the show. Hes going to keep on supplying those moments, in his inimitable awe-inspiring and mortifying way, until you finally agree to watch the show.

The Bezos, Musk and Branson billionaire space race is happening right now – Yahoo Finance Australia

Posted: at 10:00 am

With a presidential election, the Summer Olympic Games in Tokyo and yes, Ludwig van Beethovens 250th birthday celebration, 2020 promises to be a humdinger of a year.

But also happening in 2020if all systems are gowill be the beginning of regular U.S. space tourism flights, either by Richard Bransons Virgin Galactic (ticker: SPCE) or Jeff Bezos Blue Origin or both. Also possibly coming this year are tourist trips to the International Space Station (ISS) on a craft built by Elon Musks SpaceX. (Boeing has a spaceship too, but that company might be otherwise occupied.)

So apologies to Donald, the International Olympic Committee (IOC) and Ludwig van, but commercial space travel could end up being the biggest damn thing to happen this year. In fact, I think its the beginning of a real game-changer for humanity.

If youve been following the space biz, you know that the go year has been pushed back a number of times, but Ann Kim, aerospace banker and managing director of Silicon Valley Bank, is feeling it. These companies are close. They wanted to get humans into space in 2019, but were not as successful in delivering promises as originally thought. 2020 is a good year to see that inflection point.

It has been a long time coming. In fact these three companies are more or less of the same vintage. Bezos founded Blue Origin (named after Earth, the blue planet, as the place of origin), in 2000. SpaceX, which has colonizing Mars as its ultimate mission, was founded in 2002. And Branson started Virgin Galactic two years after that.

While you may snort at all this silly space stuff, its worth noting that three of the most successful entrepreneurs of our lifetimes have been working on space travel for a collective 54 years now. Remember, once upon a time folks laughed at online bookstores, electric cars and branded air travel too.

Yes, there is a bit of a space race going on, although this time its not Russia v. the U.S., its Branson v. Bezos, who are battlingin the suborbital space (pun intended), with Musk as a competitor longer term on more ambitious projects.

Some play down the competitive aspects of the business though. Its not a race at all, future Virgin Galactic passenger Namira Salim told Yahoo Finances The Final Round, we all say that in the industry. I think its safe to say there is room for all three. (Space is a big place, right?)

Its important to remember that intermittent space tourism has been around for a while. Between 2001 and 2009, seven space tourists traveled to the International Space Station on a Russian Soyuz spacecraft. Dennis Tito was the first, remember him? Also top Microsoft exec Charles Simonyi made the trip. And British singer Sarah Brightman signed up but later canceled. The trips were arranged by a U.S. company, Space Adventures, and cost, gulp, $20 million a pop. But the Russians terminated the program and despite talk of restarting it, havent. In any event the Soyuz trips were always one-offs, where Virgin Galactic and Blue Origin aim to be scheduled operations and the first steps to more extensive programs.

Virgin Galactic has been a moonshot of a stock over the past month, up over 60%. Some of that might have to do with CEO George Whitesides telling CNBC recently that demand for tickets keeps ticking up by a good chunk every month.The company says it has sold tickets to more than 600 customers at around $250,000 per person. It froze ticket sales after a crash in 2014 killed one of its pilots. Virgin Galactic now says it may reopen sales later this yearand raise prices.

Story continues

Yes, there is risk. This is not as safe as airline travel, says Jonathan McDowell, an astronomer and rocket expert at the Harvard-Smithsonian Center for Astrophysic. Suborbital flight, [what Virgin Galactic and Blue Origin are doing now] can be made very safe. It will just take a lot more flights and experience to make it so. Whether orbital flight will ever be that safe is more of an open question. Sir Richard says not to worry. Hell be going up as Virgin Galactics first test-space-tourist astronaut.

Branson took his company public by merging with Social Capital Hedosophia Holdings Corp, a special purpose acquisition company (SPAC), or blank-check company, founded by Chamath Palihapitiya, a former Facebook executive (who has since somewhat famously soured on his former employer.) Palihapitiya still owns 49% of Virgin Galactic.

Blue Originits motto is, Gradatim Ferociter, Latin for "Step by Step, Ferociously.hasnt pre-sold any tickets, but it too has indicated that the time is near to send passengers into space. The company just moved into a swank new 232,000-square-foot headquarters in Kent, Washingtonnear the Sea-Tac Airportto house many of its 2,500 employees. Geek Wire reports, Hundreds more are based elsewhere in the Kent area, south of Seattle, as well as at Blue Origins suborbital launch site in West Texas, the Florida rocket factory where Blue Origins New Glenn orbital-class rocket will be assembled, and at the site of its future BE-4 rocket engine factory in Alabama.

Bezos, who loved space as a child, is incredibly passionate about space and Blue Origin, so much so that I pulled these two quotes from this 2018 interview to give you an idea. (The whole piece makes for good reading, btw.)

I get increasing conviction with every passing year, that Blue Origin, the space company, is the most important work that Im doing. And so there is a whole plan for Blue Origin.

And:

The only way that I can see to deploy this much financial resource is by converting my Amazon winnings into space travel. That is basically it. Blue Origin is expensive enough to be able to use that fortune. I am liquidating about $1 billion a year of Amazon stock to fund Blue Origin. And I plan to continue to do that for a long time.

Serious!

Imagine if Blue Origin ends up being a bigger deal than Amazon? Could be.

SpaceX is a different beast, not surprisingly playing at an Elon Musk, super-ambitious, Tesla-like level. With its Falcon rockets and Dragon spacecraft, SpaceX was the first private company to go into orbit. Dragon has gone to the ISS 18 times. A Falcon has orbited around the sun. And working with NASA, SpaceX is reportedly set to launch its first crewed Crew Dragon next month. Tourism to the ISS is on the agenda.

Who will launch the first U.S. space flight for tourists?

I think that Virgin Galactic is the closest, says Kim. A lot of people are putting in their deposits. It seems to be the leader of the pack. Blue Origin is close behind. SpaceX has more longer term potential. I think all three can be very successful.

Where is this all going? Space tourism needs to be more than billionaires taking selfies in space, says Tess Hatch, who once worked at SpaceX and is now a vice president at Bessemer Venture Partners, which has invested in the space business. There needs to be business reasons to be in space. Hatch says space tourism and the space economy need to catalyze business models, and cites business opportunities such as zero gravity research and pharmaceutical testing.

As for Bezos, Branson and Musk, Hatch says, ...these people made their billions in totally different industries and are now turning to space. They will make billions if not trillions in space.

I must admit, I have mixed feelings about space being dominated by the likes of Bezos, Branson and Musk. On the one hand I cant help but admire what theyve done as entrepreneurs. I dont think theyre evil. And they are filling a breach voided by governments abdication of having a consistent, strategic space program. So sure, go for it guys!

On the other hand, I worry about the inevitable lack of consensus that accompanies each of these three efforts. How much thinking about pure science, medicine or even art will be brought to bear in space endeavors controlled by billionaires. I guess I dont blame them or fault them, none of that thinking is necessarily their purview or responsibility.

In a way its just another example of our economy and society being co-opted by the technocrat class. Amazon, Microsoft, Facebook, Teslathose companies are all name-checked in this article. Fifty years ago, yes there were private defense contractors involved in the process, but NASA and DOD were the drivers. The amount of technological innovation and products that came from NASA is stunning and too long to list here. Now the script has been flipped. Will these tech moguls be so free with their IP? Who knows. Maybe they will be even more collaborative about fostering and sharing research and scientific breakthroughs.

One things for sure, it looks like we are going to find out. Maybe starting this year. (Roll over Beethoven.)

Being copycats might be key to being human – The Conversation US

Posted: at 10:00 am

Chimpanzees, human beings closest animal relatives, share up to 98% of our genes. Their human-like hands and facial expressions can send uncanny shivers of self-recognition down the backs of zoo patrons.

Yet people and chimpanzees lead very different lives. Fewer than 300,000 wild chimpanzees live in a few forested corners of Africa today, while humans have colonized every corner of the globe, from the Arctic tundra to the Kalahari Desert. At more than 7 billion, humans population dwarfs that of nearly all other mammals despite our physical weaknesses.

What could account for our species incredible evolutionary successes?

One obvious answer is our big brains. It could be that our raw intelligence gave us an unprecedented ability to think outside the box, innovating solutions to gnarly problems as people migrated across the globe. Think of The Martian, where Matt Damon, trapped alone in a research station on Mars, heroically sciences his way out of certain death.

But a growing number of cognitive scientists and anthropologists are rejecting that explanation. These researchers think that, rather than making our living as innovators, human beings survive and thrive precisely because we dont think for ourselves. Instead, people cope with challenging climates and ecological contexts by carefully copying others especially those we respect. Instead of Homo sapiens, or man the knower, were really Homo imitans: man the imitator.

In a famous study, psychologists Victoria Horner and Andrew Whiten showed two groups of test subjects children and chimpanzees a mechanical box with a treat inside. In one condition, the box was opaque, while in the other it was transparent. The experimenters demonstrated how to open the box to retrieve a treat, but they also included the irrelevant step of tapping on the box with a stick.

Oddly, human children carefully copied all the steps to open the box, even when they could see that the stick had no practical effect. That is, they copied irrationally: Instead of doing only what was necessary to get their reward, children slavishly imitated every action theyd witnessed.

Of course, that study only included three- and four-year-olds. But additional research has showed that older children and adults are even more likely to mindlessly copy others actions, and young infants are less likely to over-imitate that is, to precisely copy even impractical actions.

By contrast, chimpanzees in Horner and Whitens study only over-imitated in the opaque condition. In the transparent condition where they saw that the stick was mechanically useless they ignored that step entirely, merely opening the box with their hands. Other research has since supported these findings.

When it comes to copying, chimpanzees are more rational than human children or adults.

Where does the seemingly irrational human preference for over-imitation come from? In his book The Secret of Our Success, anthropologist Joseph Henrich points out that people around the world rely on technologies that are often so complex that no one can learn them rationally. Instead, people must learn them step by step, trusting in the wisdom of more experienced elders and peers.

For example, the best way to master making a bow is by observing successful hunters doing it, with the assumption that everything they do is important. As an inexperienced learner, you cant yet judge which steps are actually relevant. So when your bands best hunter waxes his bowstring with two fingers or touches his ear before drawing the string, you copy him.

The human propensity for over-imitation thus makes possible what anthropologists call cumulative culture: the long-term development of skills and technologies over generations. No single person might understand all the practical reasons behind each step to making a bow or carving a canoe, much less transforming rare earth minerals into iPhones. But as long as people copy with high fidelity, the technology gets transmitted.

Ritual and religion are also domains in which people carry out actions that arent connected in a tangible way with practical outcomes. For example, a Catholic priest blesses wafers and wine for Communion by uttering a series of repetitive words and doing odd motions with his hands. One could be forgiven for wondering what on Earth these ritualistic acts have to do with eating bread, just as a chimpanzee cant see any connection between tapping a stick and opening a box.

But rituals have a hidden effect: They bond people to one another and demonstrate cultural affiliation. For an enlightening negative example, consider a student who refuses to stand for the Pledge of Allegiance. Her action clearly telegraphs her rejection of authorities right to tell her how to behave. And as anthropologist Roy Rappaport pointed out, ritual participation is binary: Either you say the pledge or you dont. This clarity makes it easily apparent who is or isnt committed to the group.

In a broader sense, then, over-imitation helps enable much of what comprises distinctively human culture, which turns out to be much more complicated than mechanical cause and effect.

At heart, human beings are not brave, self-reliant innovators, but careful if savvy conformists. We perform and imitate apparently impractical actions because doing so is the key to learning complex cultural skills, and because rituals create and sustain the cultural identities and solidarity we depend on for survival. Indeed, copying others is a powerful way to establish social rapport. For example, mimicking anothers body language can induce them to like and trust you more.

So the next time you hear someone arguing passionately that everyone should embrace nonconformity and avoid imitating others, you might chuckle a bit. Were not chimpanzees, after all.

Amazon plots Last Days series, updates Lord of the Rings, Wheel of Time, more – SYFY WIRE

Posted: at 10:00 am

Fantasy and science fiction will be a big part of Amazons plans for the coming year and beyond, with the streaming giant's studio heads serving up fresh news on brand-new projects, as well as updates to ones we already know about.

With SYFY WIRE in attendance, Amazon Studios head Jennifer Salke revealed at todays Television Critics Association press tour that a dark new science fiction series is in the works as part of an overall creative deal with Oscar-winning 12 Years a Slave director Steve McQueen.

Titled Last Days, the series is described by Amazon's official releaseas a gripping sci-fi thriller set in a future in which Earth is dying, AI is on the rise, and the worlds governments have secretly created a controversial plan to selectively colonize Mars. The show will follow one womans journey to explore the truth about where she came from, at the risk of losing everything she knows.

Via therelease, Amazon said Last Days is already in development from Lammas Park and See-Saw Films, with McQueen adding that hes thrilled about this new venture and partnership with Amazon. The idea of having a partner that will support and facilitate risk and change is more than exciting.

Turning its eyes toward the Shire, Amazon also offered a handful of updates on its hugely-anticipated, mega-budget series adaptation of Lord of The Rings, with Salke sharing onstage that development is moving along with table reads happening in New Zealand ahead of a production start slated to begin next month.

Amazon co-head of TV Vernon Sanders also shared a bevy of fresh new names wholl be rounding out the LOTR cast, including some you may not have heard of before: Owain Arthur, Nazanin Boniadi, Morfydd Clark,and Australian actor Tom Budge. The new additions joined previously-reported cast members Ema Horvath, Markella Kavenagh, Joseph Mawle, and Robert Aramayo as Beldor, one of the series still-mysterious lead characters.

Sanders also sharedthe studios enthusiasm with development progress on The Wheel of Time, the series adaptation of author Robert Jordans iconic fantasy series. We are well underway in production. We love what weve seen, he said at the press tour, teasing that more information is on the way for when the show will arrive. Big, world-building shows take time to craft. I have a quarter [of the year] Im thinking [of the series] dropping, but will have news later in the year.

Amazon also served upnews of an intriguing new project that sounds like it may share at least a little creative inspiration with a certain special agent who likes his martinis shaken; not stirred: Citadel, a truly global action-packed spy series, according toSalke's press tour remarks, from the Russo brothers AGBO Films and starring Quanticos Priyanka Chopra and Game of Thrones' Richard Madden.

Joe and Anthony Russo will serve as executive producers on Citadel, with Josh Appelbaum, Andr Nemec, Jeff Pinkner, and Scott Rosenbergof production company Midnight Radio serving as writers and executive producers. The multi-faceted event series will be headlined, according to Amazon's press release, with the mothership United States edition starring Chopra and Madden, and will also feature a constellation of additional, local-language editions originating in Mexico, as well as previously-announced versions in Italy and India.

Finally, it sounds as though Amazon is delighted in its new role as the home of The Expanse, with Sanders telling TCA membersthe studio is thrilled with the fourth season and quality of the work, and that its been especially cool to snag new viewers as the show has made the transition from its original network spot at SYFY. The thing that has thrilled us is how many new fans who have come in, said Sanders, adding, were just seeing episodes for Season 5.
