Some of the greatest destruction to Italy's artistic heritage has been in Amatrice, voted one of its most beautiful towns
Art experts fear numerous historic Italian buildings and their contents were damaged in Wednesday's earthquake, across a region where almost every hilltop town and village has beautiful churches and monuments.
The Dutch classicist David Rijser, an expert on the culture of Abruzzo, said there had been damage to the central region's many churches, funeral monuments and museums. “It has been a true drama, there is a lot that has been lost,” he told Dutch radio.

Continue reading...In the 1960s, British architectural critic Reyner Banham declared his love for the city that his fellow intellectuals hated. What Banham wrote about Los Angeles redefined how the world perceived it but what would he think of LA today?
“Now I know subjective opinions can vary,” the journalist Adam Raphael wrote in the Guardian in 1968, “but personally I reckon LA as the noisiest, the smelliest, the most uncomfortable and most uncivilised major city in the United States. In short, a stinking sewer ...”
Three years later, Raphael's words appeared in print again as an epigraph of Reyner Banham's Los Angeles: The Architecture of Four Ecologies the most exuberantly pro-Los Angeles book ever written. Ever since publication, it has shown up on lists of great books about modern cities even those drawn up by people who consider Los Angeles anything but a great American city.
Los Angeles offers radical alternatives to almost every urban concept in unquestioned currency.

Astronomers using European Southern Observatory (ESO) telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us -- and it may also be the closest possible abode for life outside the Solar System.
Just over four light-years from the Solar System lies a red dwarf star that has been named Proxima Centauri as it is the closest star to Earth apart from the Sun. This cool star in the constellation of Centaurus is too faint to be seen with the unaided eye and lies near to the much brighter pair of stars known as Alpha Centauri AB.
During the first half of 2016 Proxima Centauri was regularly observed with the HARPS spectrograph on the ESO 3.6-metre telescope at La Silla in Chile and simultaneously monitored by other telescopes around the world. This was the Pale Red Dot campaign, in which a team of astronomers led by Guillem Anglada-Escudé, from Queen Mary University of London, was looking for the tiny back and forth wobble of the star that would be caused by the gravitational pull of a possible orbiting planet.
As this was a topic with very wide public interest, the progress of the campaign between mid-January and April 2016 was shared publicly as it happened on the Pale Red Dot website and via social media. The reports were accompanied by numerous outreach articles written by specialists around the world.
Guillem Anglada-Escudé explains the background to this unique search: "The first hints of a possible planet were spotted back in 2013, but the detection was not convincing. Since then we have worked hard to get further observations off the ground with help from ESO and others. The recent Pale Red Dot campaign has been about two years in the planning."
The Pale Red Dot data, when combined with earlier observations made at ESO observatories and elsewhere, revealed the clear signal of a truly exciting result. At times Proxima Centauri is approaching Earth at about 5 kilometres per hour -- normal human walking pace -- and at times receding at the same speed. This regular pattern of changing radial velocities repeats with a period of 11.2 days. Careful analysis of the resulting tiny Doppler shifts showed that they indicated the presence of a planet with a mass at least 1.3 times that of the Earth, orbiting about 7 million kilometres from Proxima Centauri -- only 5% of the Earth-Sun distance.
Guillem Anglada-Escudé comments on the excitement of the last few months: "I kept checking the consistency of the signal every single day during the 60 nights of the Pale Red Dot campaign. The first 10 were promising, the first 20 were consistent with expectations, and at 30 days the result was pretty much definitive, so we started drafting the paper!"
Red dwarfs like Proxima Centauri are active stars and can vary in ways that would mimic the presence of a planet. To exclude this possibility the team also monitored the changing brightness of the star very carefully during the campaign using the ASH2 telescope at the San Pedro de Atacama Celestial Explorations Observatory in Chile and the Las Cumbres Observatory telescope network. Radial velocity data taken when the star was flaring were excluded from the final analysis.
Although Proxima b orbits much closer to its star than Mercury does to the Sun in the Solar System, the star itself is far fainter than the Sun. As a result Proxima b lies well within the habitable zone around the star and has an estimated surface temperature that would allow the presence of liquid water. Despite the temperate orbit of Proxima b, the conditions on the surface may be strongly affected by the ultraviolet and X-ray flares from the star -- far more intense than the Earth experiences from the Sun [4].
Two separate papers discuss the habitability of Proxima b and its climate. They find that the existence of liquid water on the planet today cannot be ruled out and, in such case, it may be present over the surface of the planet only in the sunniest regions, either in an area in the hemisphere of the planet facing the star (synchronous rotation) or in a tropical belt (3:2 resonance rotation). Proxima b's rotation, the strong radiation from its star and the formation history of the planet makes its climate quite different from that of the Earth, and it is unlikely that Proxima b has seasons.
This discovery will be the beginning of extensive further observations, both with current instruments and with the next generation of giant telescopes such as the European Extremely Large Telescope (E-ELT). Proxima b will be a prime target for the hunt for evidence of life elsewhere in the Universe. Indeed, the Alpha Centauri system is also the target of humankind's first attempt to travel to another star system, the StarShot project.
Guillem Anglada-Escudé concludes: "Many exoplanets have been found and many more will be found, but searching for the closest potential Earth-analogue and succeeding has been the experience of a lifetime for all of us. Many people's stories and efforts have converged on this discovery. The result is also a tribute to all of them. The search for life on Proxima b comes next..."

The Chinese government has unveiled plans to build a permanently manned radar station on the moon to monitor Earth. The project was launched earlier this year and received funding from the National Natural Science Foundation of China. The proposed facility, which may include quarters for astronauts and a powerful radar antenna array at least 50 meters high, could monitor wider areas of our planet than existing satellites, according to scientists involved in the study.
The base, which would be used for scientific research and defense monitoring, could also produce more powerful and clearer images of earth as the high-frequency microwaves emitted by the radar station could not only penetrate cloud, but also the earth's surface, allowing it to monitor areas on land, under the sea and underground.
Leading space scientists in China have joined the radar station project. The team held a two-day brainstorming session at the Fragrant Hill Hotel in Beijing last month. Those taking part included Yan Jun, the director of the National Astronomical Observatories; Professor Lin Yangting, a planetary researcher whose team discovered evidence of coal-like carbon in an asteroid; and senior scientists from China's unmanned lunar exploration missions. The team leader is Professor Guo Huadong, a top radar technology expert at the Chinese Academy of Sciences.
Guo initially proposed the moon-based radar station in a research paper in the journal Science China Earth Sciences three years ago, suggesting that the moon had numerous advantages over satellites or a space station as an earth observation platform, including stability and the unlimited durability of any complex on the lunar surface.
The data collected by lunar radar would help with a wide range of scientific research issues such as monitoring extreme weather conditions, global earthquake activity, agricultural production and the collapse of the polar ice caps, he wrote.
To generate high intensity radio beams that could reach earth, the radar station would need an enormous amount of power so a solar or nuclear power plant would have to be built, Guo said in the paper.
The radar would generate at least 1.4 gigabytes of data each second, a volume far exceeding the bandwidth of current long-distance space communications technology, but this would not be a problem if the station was manned by astronauts who could process the information on site, he added.
Guo gave no precise estimate on costs for the project, but cautioned it would be “very expensive”. He did not respond to requests for comment.
Many researchers interviewed by the South China Morning Post, however, expressed scepticism about the scheme, arguing it was a waste of money, time and human resources. “It's a lunatic idea,” said one mainland space scientist informed of the project, but not directly involved. The cost of building such as a large scale facility on the moon would be “higher than filling the sky with a constellation of spy satellites”, which could “do the same job at only a fraction of the cost”, said the scientist, who declined to be named due to the sensitivity of the issue.
“Either the radar has to be extremely powerful, or the antenna extremely large, otherwise it won't be able to pick up the radio waves bouncing back from the Earth,” said Professor Zhou Yiguo, a radar technology researcher at the Chinese Academy of Sciences. “It is an important subject of research, but whether its advantage over satellite constellations can adjust the high cost and risk will need careful evaluation.”
The lunar radar project comes as China shows signs of wanting to play a leading role in a renewed race to the moon, according to some space experts.
The design of a giant rocket the same size as the Saturn V in the US Apollo missions will be completed by 2020 to pave way for large scale activities in space including a “manned moon landing”, according to a scientific and technological innovation plan announced by the central government earlier this month.
China's scientific authorities appear optimistic about the prospects for the lunar radar base, despite the concerns voiced by some experts.

Neurons that fire together wire together, say scientists at Columbia University, suggesting that the three-pound computer in our heads may be more malleable than we think. Their findings suggest that groups of activated neurons may form the basic building blocks of learning and memory.
“I always thought the brain was mostly hard-wired,” said the study's senior author, Dr. Rafael Yuste, who is co-director of the Kavli Institute for Brain Science (KIBS). “But then I saw the results and said ‘Holy moly, this whole thing is plastic.' We're dealing with a plastic computer that's constantly learning and changing.”
The neuroscientists demonstrated that a set of neurons trained to fire in unison could be reactivated as much as a day later if just one neuron in the network was stimulated.
The researchers were able to control and observe the brain of a living mouse using the optogenetic tools that have revolutionized neuroscience in the last decade. They injected the mouse with a virus containing light-sensitive proteins engineered to reach specific brain cells. Once inside a cell, the proteins allowed researchers to remotely activate the neuron with light, as if switching on a TV.

The mouse was allowed to run freely on a treadmill while its head was held still under a microscope. With one laser, the researchers beamed light through its skull to stimulate a small group of cells in the visual cortex. With a second laser, they recorded rising levels of calcium in each neuron as it fired, thus imaging the activity of individual cells.
Before optogenetics, scientists had to open the skull and implant electrodes into living tissue to stimulate neurons with electricity and measure their response. Even a mouse brain of 100 million neurons, nearly a thousandth the size of ours, was too dense to get a close look at groups of neurons.
In the above video, neurons repeatedly stimulated with light are trained to work together. They can be reactivated as a group if just one neuron is stimulated as much as a day later. The experiments are detailed in a new study in the journal Science.(Credit: Yuste Lab/Columbia University)
Optogenetics allowed researchers to get inside the brain non-invasively and control it far more precisely. In the last decade, researchers have restored sight and hearing to blind and deaf mice, and turned normal mice aggressive, all by manipulating specific brain regions.
The breakthrough that allowed researchers to reprogram a cluster of cells in the brain is the culmination of more than a decade of work. With tissue samples from the mouse visual cortex, Yuste and his colleagues showed in a 2003 study in Nature that neurons coordinated their firing in small networks called neural ensembles. A year later, they demonstrated that the ensembles fired off in sequential patterns through time.
As techniques for controlling and observing cells in living animals improved, they learned that these neural ensembles are active even without stimulation. They used this information to develop mathematical algorithms for finding neural ensembles in the visual cortex. They were then able to show, as they had in the tissue samples earlier, that neural ensembles in living animals also fire one after the other in sequential patterns.
The current study in Science shows that these networks can be artificially implanted and replayed, says Yuste, much as the scent of a tea-soaked madeleine takes novelist Marcel Proust back to his memories of childhood.
Pairing two-photon stimulation technology with two-photon calcium imaging allowed the researchers to document how individual cells responded to light stimulation. Though previous studies have targeted and recorded individual cells none have demonstrated that a bundle of neurons could be fired off together to imprint what they call a “neuronal microcircuit” in a live animal's brain.
“If you told me a year ago we could stimulate 20 neurons in a mouse brain of 100 million neurons and alter their behavior, I'd say no way,” said Yuste, who is also a member of the Data Science Institute. “It's like reconfiguring three grains of sand at the beach.”
The researchers think that the network of activated neurons they artificially created may have implanted an image completely unfamiliar to the mouse. They are now developing a behavioral study to try and prove this.
“We think that these methods to read and write activity into the living brain will have a major impact in neuroscience and medicine,” said the study's lead author, Luis Carrillo-Reid, a postdoctoral researcher at Columbia.

The European Service Module that will power NASA's Orion spacecraft to the Moon and beyond is taking shape in the assembly hall at Airbus Defence and Space, Bremen, Germany. The spacecraft module will provide propulsion, electricity, water, oxygen and nitrogen and thermal control.
Seen here is the primary structure that provides rigidity to the European Service Module much like the chassis of a car. It absorbs the vibrations and energy from launch while a secondary structure protects the module from micrometeoroids and space debris.
Assembly of the thousands of components needed to build the advanced spacecraft started on 19 May with the arrival of the primary structure that was shipped from Turin, Italy, by Thales Alenia Space. In 2018 this structure will be an element of the European Service Module that will be launched into space, as part of the Orion spacecraft, on its first mission to fly more than 64 000 km beyond the Moon and back.
In the background is a poster of ESA's Automated Transfer Vehicle (ATV) that was also assembled in this hall in Bremen.

Find out just how abundant water is in the Cosmos, when cosmochemist Natalie Starkey hosts StarTalk All-Stars for the first time. She's joined by co-host Chuck Nice and planetary scientist Lindy Elkins-Tanton. Get the scoop on new evidence that suggests most of Earth's water didn't come from comets, but rather from the same rocky material that built up our planet. Explore whether a planet is “born wet” or not, and how the formation of a celestial body determines what kind of water it has.
Is the water ice on comets salty, fresh, or just “dirty” with minerals and “gloopy” from complex organic hydrocarbons? Would comets and asteroids be more useful providing water for Earth, or as fueling stations for space exploration, providing hydrogen for fuel, oxygen for breathing and water for drinking?
Natalie and Lindy look at the status of water here on Earth, from pollution, to scarcity, to the lack of regulations protecting our aquifers. And of course, no discussion about space water would be complete without pondering the possibility of life, whether in the ancient subsurface oceans of Jupiter's moon Europa and Saturn's moon Enceladus (below), or on one of the 600 million Earth-like exoplanets scattered throughout the universe. Lindy also shares the story of when she first “made” water in a lab by burning hydrogen, and you'll hear why, for humans, there's no man-made alternative to water.

The discovery of a rocky planet in the habitable zone around our sun's nearest star is just the beginning of decades of intense research and exploration
Has life gained a foothold on a planet that orbits our nearest star? The question, a variation on one of the greatest mysteries humans have pondered, is now front and centre in astronomers' minds. The short answer, of course, is nobody knows. But over the coming months, years and decades, scientists will throw every instrument and clever technique they have at Proxima b, an Earth-sized planet warmed by a small, cool star in Centaurus, to find out.

Continue reading...The newly discovered exoplanet Proxima b could hold the answer to the perennial question: is there life elsewhere in the universe?
Nature could hardly have been kinder to us. The discovery of a potentially habitable planet on our astronomical doorstep is nothing short of astronomers' wildest dreams coming true.
In a world where discoveries seem to be coming thick and fast (think water on Mars, gravitational waves, Higgs boson) it is vitally important that we now focus our efforts on learning all we can about this tantalising world because of its potential to tell us something about life elsewhere in the universe.

WPP has released its interim results, revealing signs of cautious optimism for its businesses, which have generally stood up well since Britain voted to leave the EU.
This has partly been put down to the falling value of the pound. In its analysis of current trading, WPP says that there was strong trading in the UK in July, which may be a reflection of a “post-Brexit vote recovery, driven by a weaker pound sterling.”
July has been a positive month across all WPP regions and sectors with like-for-like revenue and net sales up 4.6% and 1.9% respectively.
The main results give a view of the financial performance of the group for the six months preceding 30 June 2016.
As a group WPP has posted pre-tax profits of £690 million, which is up 15.8%. Meanwhile constant currency revenue a measure which eliminates the effect of exchange rate fluctuations is up 8.9% and like-for-like revenue is up 4.3%.
In the UK “pre-Brexit vote uncertainties” were cited as a reason for a slow-down in growth, which stood at 3.5% in the second quarter, but 4.7% in the second quarter of this year.
Internationally, branding and identity, which is grouped together with healthcare and specialist communications, showed like-for-like net sales growth of 3.7% in the second quarter, compared with 5.2% in the first quarter.
However, the branding and identity, direct, digital and interactive groups margins were “up strongly” and it was the healthcare and specialist communications businesses which had put pressure on the sector.
UK-based WPP design consultancies include Brand Union, Coley Porter Bell, Fitch, Landor and The Partners.

DesignStudio has unveiled a new visual identity for Future Finance, which looks to reconcile serious subjects such as student loans, with an attention grabbing new look.
It needed to appeal to wide range of student customers, including undergraduates, medical students, lawyers and MBA graduates.
The redesign, which includes a different logo and website, centres on “the individual paths we all take to realise our potential”, according to DesignStudio.
The consultancy has used a series of joined-up, distinctive shapes, intended to be a connector between the customer and their future self.
Alongside the kit of Perspex shapes, an “optimistic”, bright colour palette has been used throughout to “side-step the cold, functional world of finance to speak directly to students and their potential,” says the consultancy.
Speaking about the rebrand, DesignStudio's executive creative director, James Hurst, says: “The opportunity that Future Finance offers its customers is extraordinary.”
“Capturing that ambition and impact on real lives means being brave and being bold. This is an identity that signals a brand both connected to you and your connection to a more enriching future.”

You know what I would love to see two brands swapping employees for a month. I spent years working on internal brand campaigns and looking at the business from the inside. Instead of an external facing brand collaboration, I would like to see an internal one.
Think the Gucci folk swapping with VOLVO Group's staff, or Nike's people swapping with HSBC's brand team. I am true believer that their people are part of their brand, so this could be a fantastic experience to see just how true they are to it.
The result could be a great PR story and the ideas may spawn new collaboration as well. Anyone wanna give it a go? I'll facilitate.
I'd have to opt for two very disparate entities in Southeastern trains and Amazon. One delivers packages smoothly and efficiently across the globe in such an effortless manner that it's difficult to remember a time before they existed.
The other tries desperately to deliver passengers from one destination to another across a comparatively small network but fails dismally, if the comments of their human cargo are anything to go by.
I can't think of another service industry that has its own Facebook page, I Hate Southeastern trains (note the capital H in Hate, incidentally), dedicated to its general incompetence.
I know there will be many mitigating factors in why they provide such a poor service such as investment in the business, and no doubt union power. However, in a fanciful world wouldn't those commuters view their carriages in a totally new light if they were emblazoned with the Amazon logo? I'm sure it would bring a smile to their faces too.
Recognising an affinity with another brand or spotting a niche, technology or craft that would complement each other brings a whole new level of brand experience and recognition to the customer.
Nike and Liberty have done it so well and I'm eagerly awaiting the outcome of the IKEA and Tom Dixon collaboration.
But rather than a visual or tech collaboration, I'm interested in how charities and brands can collaborate for the better. Viewed favourably by many but controversially in some communities, it could be interesting to encourage an organisation such as Airbnb with the ethos of Belong Anywhere to collaborate with Shelter, the charity campaigning for a home for everyone.
Could there be an Airbnb community shelter in highly populated city communities, a contribution from Airbnb, working with Shelter to help people to really “Belong Anywhere”?

So I'd love to see the billion-pound bounder that ties WHSmith up with a smart brand to help save its desperately awful stores.
Could Google save them? It organises the entire internet and makes it useful — perhaps it could reorganise the endless upset of 2kg bars of chocolate being attached to your morning newspaper purchase?

A Russian graphic designer named Mike Levchenko is doing his part to mend the icy relationship between his country and the West — or at least Western capitalism — by reimagining a half-dozen global brands as if they were from the Soviet Union.
Levchenko took the logos of McDonald's, Nikon, Samsung, Dior, Apple, Chanel, and Mercedes-Benz, and gave them a Cyrillic spin. Apple's is boxy, but with an unmistakable leaf growing from the first letter. Dior's is cursive and feminine. Mercedes gets a couple spear points to suggest speed. Levchenko also paired each logo with an advertisement, most of which appear modeled on Soviet era ads from the 1950s and ‘60s.
First designed by monks in Bulgaria in the ninth century (shout-out to The Verge's...
Mozilla, the open web pioneer, is staying true to its collaborative and open roots by performing a brand redesign right out in public. The company has published its shortlist of new logo proposals, which it will now consider, refine, and whittle down to create its next brand identity. Among them is the above, seemingly abstract, structure that actually spells out Mozilla's name in its multicolored isometric shapes.
There's another quirky design that incorporates various colors and shapes to spell out "Mozilla":
And then there are few more staid and predictable variants:
The unifying feature of all of the redesign concepts is that they're carefully thought through. And even where you might say their...
The proprietors of Fortaleza Tours have a fragile truce within the "red zone" of Panama City. In the eyes of Panamanian law, once you make it to a gang list, there's no way off. But Fortaleza wants to change that. Not long ago, their tour guides may have been the ones to rob foreigners wandering through the area. Now, former gang members give tourists a behind-the-scenes look at their past gangland life, and all financial transactions with the tourists are voluntary. This documentary by MEL Films, Gang Tours of Panama, shows how violence is waning, the hospitality sector is moving in, and a relatively new feeling of safety has returned to the historic center of Panama City.

The handsome black-and-white ruffed lemur is, along with the red ruffed lemur, the largest member of the Lemuridae family. This species inhabits lowland to mid-altitude rain forests in eastern Madagascar.
Listed as Critically Endangered as the species is suspected to have undergone a population decline of ≥80% over a period of 21 years (three generations), primarily due to observed and inferred continuing decline in area, extent and quality of habitat from slash-and-burn agriculture, logging and mining, in addition to exploitation through unsustainable hunting pressure.
These causes have not ceased, and will to a large extent not be easily reversible.

The city of Karlsruhe, Germany was planned with a palace tower at its center, surrounded by 32 radiating streets. Because the design resembled the ribs of a folding fan, the city is sometimes called the “fan city” or “Fächerstadt.“ Additionally, this city's urban plan gave rise to the geometry concept of “Karlsruhe Metric” which refers to a measure of distance that assumes travel is only possible along radial streets and along circular avenues around the center.

Central Italy was struck by a powerful, shallow, 6.2-magnitude earthquake at 3:36 am local time, devastating several mountain villages, and resulting in at least 73 deaths so far. Buildings in towns close to the epicenter collapsed on top of each other, falling into the streets, trapping hundreds in enormous piles of rubble. The death toll is still expected to rise as rescue teams reach some of the more remote villages in the region.

James Weddell Scientist of the Day
James Weddell, a British sealer and ship's captain, was born Aug. 24, 1787.
Note: This is a follow-up to my previous piece, "Understanding Trump." Please read that piece first.)
The Responsible Reporter's Problem
Responsible reporters in the media normally transcribe political speeches so that they can accurately report them. But Donald Trump's discourse style has stumped a number of reporters. Dan Libit, CNBC's excellent analyst is one of them. Libit writes:
His unscripted speaking style, with its spasmodic, self-interrupting sentence structure, has increasingly come to overwhelm the human brains and tape recorders attempting to quote him.
Trump is, simply put, a transcriptionist's worst nightmare: severely unintelligible, and yet, incredibly important to understand.
Given how dramatically recent polls have turned on his controversial public utterances, it is not hyperbolic to say that the very fate of the nation, indeed human civilization, appears destined to come down to one man's application of the English language -- and the public's comprehension of it. It has turned the rote job of transcribing into a high-stakes calling.
...
Trump's crimes against clarity are multifarious: He often speaks in long, run-on sentences, with frequent asides. He pauses after subordinate clauses. He frequently quotes people saying things that aren't actual quotes. And he repeats words and phrases, sometimes with slight variations, in the same sentence.
Some in the media (Washington Post, Salon, Slate, Think Progress, etc.) have called Trump's speeches "word salad." Some commentators have even attributed his language use to "early Alzheimer's," citing "erratic behavior" and "little regards for social conventions." I don't believe it.
I have been repeatedly asked in media interviews about such use of language by Trump. So far as I can tell, he is simply using effective discourse mechanisms to communicate what his wants to communicate to his audience. I have found that he is very careful and very strategic in his use of language. The only way I know to show this is to function as a linguist and cognitive scientist and go through details.
Let's start with sentence fragments. It is common and natural in New York discourse for friends to finish one another's sentences. And throughout the country, if you don't actually say the rest of a friend's sentence out loud, there is nevertheless a point at which you can finish it in your head. When this happens in cooperative discourse, it can show empathy and intimacy with a friend, that you know the context of the narrative, and that you understand and accept your friend's framing of the situation so well that you can even finish what they have started to say. Of course, you can be bored with, or antagonistic to, someone and be able to finish their sentences with anything but a feeling of empathy and intimacy. But Trump prefers to talk to a friendly crowd.
Trump often starts a sentence and leaves off where his followers can finish in their minds what he has started to say. That is, they commonly feel empathy and intimacy, an acceptance of what is being said, and good feeling toward the speaker. This is an unconscious, automatic reaction, especially when words are flying by quickly. It is a means for Trump to connect with his audience.
The Second Amendment Incident
Here is the classic case, the Second Amendment Incident. The thing to be aware of is that his words are carefully chosen. They go by quickly when people hear them. But they are processed unconsciously first by neural circuitry -- and neurons operate on a thousandth-of-a-second time scale. Your neural circuitry has plenty of time to engage in complex forms of understanding, based on what you already know.
Trump begins by saying, "Hillary wants to abolish, essentially abolish the Second Amendment." He first just says "abolish," and then hedges by adding "essentially abolish." But having said "abolish" twice, he has gotten across the message that she wants to, and is able to, change the Constitution in that way.
Now, at the time the Second Amendment was written, the "arms" in "bear arms" were long rifles that fired one bullet at a time. The "well-regulated militia" was a local group, like a contemporary National Guard unit, regulated by a local government with military command structure. They were protecting American freedoms against the British.
The Second Amendment has been reinterpreted by contemporary ultra-conservatives as the right of individual citizens to bear contemporary arms (e.g., AK-47's), either to protect their families against invaders or to change a government by armed rebellion if that government threatens what they see as their freedoms. The term "Second Amendment" activates the contemporary usage by ultra-conservatives. It is a dog-whistle term, understood in that way by many conservatives.
Now, no president or Supreme Court could literally abolish any constitutional amendment alone. But a Supreme Court could judge that that certain laws concerning gun ownership could be unconstitutional. That is what Trump meant by "essentially abolish."
Thus, the election of Hillary Clinton threatens the contemporary advocates of the 'Second Amendment.'
Trump goes on:
"By the way, and if she gets to pick [loud boos] -- if she gets to pick her judges, nothing you can do, folks. Although the Second Amendment people, maybe there is, I don't know."
Here are the details.
"By the way," marks a parallel utterance, one that does not linearly follow from what was just said, but that has information relevant to what was just said.
"And" here marks information that follows from what was just said.
"If she gets to pick ..." When said the first time, it was followed immediately by loud boos. The audience could finish the if-clause for themselves, since the word "pick" in context could only be about Hillary picking liberal judges. Trump goes on making this explicit, "if she gets to pick her judges..."
"Gets to" is important. The metaphor here with "to" is that Achieving a Purpose Is Reaching a Destination" with the object of "to" marking the pick. The "get" in "get to" is from a related metaphor, namely, that Achieving a Purpose Is Getting a Desired Object. In both Purpose metaphors, the Achievement of the Purpose can be stopped by an opponent. The "if," indicates that the achievement of the purpose is still uncertain, which raises the question of whether it can be stopped.
"Her judges" indicates that the judges are not your judges, from which it follows that they will not rule the way you want them to, namely, for keeping your guns. The if-clause thus has a consequence: unless Hillary is prevented from becoming president, "her judges" will change the laws to take away your guns and your Constitutional right to bear arms. This would be a governmental infringement on your freedom, which would justify the armed intervention of ultra-conservatives, what Sharon Angle in Nevada has called the "Second Amendment solution." In short, a lot is entailed -- in little time on a human timescale, but with lots of time on a neural timescale.
Having set this up, Trump follows the if-clause with "Nothing you can do, folks." This is a shortened version in everyday colloquial English of "There will be nothing you can do, folks." That is, if you let Hillary take office, you will be so weak that you will be unable to stop her. The "folks," suggests that he and the audience members are socially part of the same social group -- as opposed to a distant billionaire with his own agenda.
Immediately after "nothing you can do," Trump goes on: "Although the Second Amendment people, maybe there is.
"Although" is a word used to contrast one possible course of events with an opposite possibility. Trump has just presented a possible course of events that is threatening to ultra-conservative Second Amendment advocates. "Although the Second Amendment people" calls up the alternative for those who would act violently to protect their Second Amendment right.
"Maybe" brings up a suggestion. "Maybe there is" suggests that there is something the "Second Amendment People" can do to prevent Hillary from taking office and appointing liberal judges who would take away what they see as their Constitutional rights.
"I don't know" is intended to remove Trump from any blame. But it acts unconsciously in the opposite way. It is like the title of the book I wrote, "Don't Think of an Elephant." The way the brain works is that negating a frame activates the frame. The relevant frame for "Second Amendment people" is use of arms to protect their rights against a government threatening to take away their rights. This is about the right to shoot, not about the right to vote. Second Amendment conservative discourse is about shooting, not about voting.
The point here is that Trump's use of language is anything but "word salad." His words and his use of grammar are carefully chosen, and put together artfully, automatically, and quickly.
Trump never overtly used the word "assassinate." He says he was just suggesting that advocates of the Second Amendment vote, and was being sarcastic. A sarcastic invocation to vote would sound very different. A sarcastic invocation to vote might be, "The American way to change things is to vote. But maybe you care so much about shooting, you won't be able to organize to vote."
He didn't say anything like that. And he chose his words very, very carefully.
Believe Me! Some People Say...
People in the media have asked me about Trump's use of "Believe me!" and "Many people say" followed by a statement that is not true, but that he wants he audience to believe. Why does he use such expressions and how do they work in discourse? To understand this, one needs to look at the concept of lying. Most people will say that a lie is a false statement. But a study by linguists Linda Coleman and Paul Kay pointed out more than 30 years ago that the situation is more complex.
If a statement happens to be false, but you sincerely believe that it is true, you are not lying in stating it. Lying involves a hierarchy of conditions defining worse and worse lies. Here is the hierarchy:
1. You don't believe it.
2. You are trying to deceive.
3. You are trying to gain advantage for yourself.
4.You are trying to harm.
As you add conditions in the hierarchy, the lies get worse and worse.
Though this is the usual hierarchy for lies, there are variations: A white lie is one that is harmless. A social lie is one where deceit is general helpful, as in, "Aunt Susie, that was such a delicious Jello mold that you made." Other variations include exaggeration, flattery, kidding, joking, etc.
Lying is a form of uncooperative discourse. But most discourse is cooperative, and there are rules governing it that the philosopher Paul Grice called "maxims" in his Harvard Lectures in 1967. Grice observed that uncooperative discourse is created when the maxims are violated. Grice's maxims were extended in the 1970's by Eve Sweetser in a paper on lying.
Sweetser postulated a Maxim of Helpfulness:
In Cooperative Discourse, people intend to help one another.
She then observed that there were two models used in helpful communication.
Though this model does not hold for all situations (e.g., kidding), they are models that are used by virtually everyone unconsciously all day every day. If I tell my wife that I saw my cousin this morning, there is no reason to deceive, so I believe it (Ordinary Communication). And since I know my cousin well, if I believe I saw him, then I did see him (Justified Belief). Such principles are part of our unconsciously functioning neural systems. They work automatically, unless they become conscious and we can attend to them and control them.
Trump uses these communication models that are in your brain. When he says "Believe me!" he is using the principle of Justified Belief, suggesting that he has the requisite experience for his belief to be true. When those in Trump's audience hear "Believe me!", they will mostly understand it automatically and, unconsciously and via Justified Belief, will take it to be true.
When Trump says, "Many people say that ..." both principles are unconsciously activated. If many people say it, they are unlikely to all or mostly be deceiving, which means they believe it, and by Justified Belief, it is taken to be true.
You have to be on your toes, listening carefully and ready to disbelieve Trump, to avoid the use of these ordinary cognitive mechanisms in your brain that Trump uses for his purposes.
Is He "On Topic?"
Political reporters are used to hearing speeches with significant sections on a single policy issue. Trump often goes from policy to policy to policy in a single sentence. Is he going off topic?
So far as I can discern, he always on topic, but you have to understand what his topic is. As I observed in my Understanding Trump paper, Trump is deeply, personally committed to his version of Strict Father Morality. He wants it to dominate the country and the world, and he wants to be the ultimate authority in this authoritarian model of the family that is applied in conservative politics in virtually every issue area.
Every particular issue, from building the wall, to using our nukes, to getting rid of inheritance taxes (on those making $10.9 million or more), to eliminating the minimum wage -- every issue is an instance of his version of Strict Father Morality over all areas of life, with him as ultimately in charge.
As he shifts from particular issue to particular issue, each of them activates his version of Strict Father Morality and strengthens it in the brains of his audience. So far as I can tell, he is always on topic -- where this is the topic.
Always Selling
For five decades, Trump has been using all these techniques of selling and trying to make deals to his advantage. It seems to have become second nature for him to use these devices. And he uses them carefully and well. He is a talented charlatan. Keeping you off balance is part of his game. As is appealing to ordinary thought mechanisms in the people he is addressing.
It is vital that the media, and ordinary voters, learn to recognize his techniques. When the media fails to grasp what he is doing, it gives him an advantage. Every time someone in the media claims his discourse is "word salad, " it helps Trump by hiding what he is really doing.
"Regret" or Excuse
One day after the above was written, Trump made a well-publicized statement of "regret."
"Sometimes, in the heat of debate and speaking on a multitude of issues, you don't choose the right words or you say the wrong thing.
I have done that.
And believe it or not, I regret it.
And I do regret it, particularly where it may have caused personal pain.
Too much is at stake for us to be consumed with these issues. ..."
He did not give any specifics.
What we have just seen is that he chooses his words VERY carefully. And he has done that here.
He starts out with "sometimes," which suggests that it is a rare occurrence on no particular occasions -- a relatively rare accident. He continues with a general, inescapable fact about being a presidential candidate, namely, that he is always "in the heat of debate and speaking on a multitude of issues." The words "heat" and "multitude" suggest that normal attention to details like word choice cannot operate in presidential campaign. In short, it is nothing that he could possibly be responsible for, and is a rare occurrence anyway.
Then he uses the word "you." This shifts perspective from him to "you," a member of the audience. You too, if you were running for president, would naturally be in such uncontrollable situations all the time, when "you don't choose the right words or you say the wrong thing." It's just a matter of choosing "the right words." This means that he had the right ideas, but under natural, and inevitable attentional stress, an unavoidable mistake happens and could happen to you: "you" have the right ideas, but mess up on the "right words."
He then admits to "sometimes" making an unavoidable, natural mistake, not in choosing the right ideas, but in word choice and, putting yourself in his shoes, "you say the wrong thing" -- that is, you are thinking the right thing, but you just say it wrong -- "sometimes."
His admission is straightforward -- "I have done that" -- as if he had just admitted to something immoral, but which he has carefully described as anything but immoral.
"And believe it or not, I regret it." What he is communicating with "believe it or not," is that you, in the audience, may not believe that I am a sensitive soul, but I really am, as shown by my statement of regret. He then emphasizes his statement of personal sensitivity: "And I do regret it, particularly where it may have caused personal pain." Note the "may have caused." No admission that he definitely DID "cause personal pain." And no specifics given. After all, they don't have to be given, because it is natural, unavoidable, accidental, and so rare as to not matter. He states this: "Too much is at stake for us to be consumed with these issues." In short, it's a trivial matter to be ignored -- because it is a natural, unavoidable, accidental mistake, only in the words not the thoughts, and is so rare as to be unimportant. All that in five well-crafted sentences!
Note how carefully he has chosen his words. And what is the intended effect? He should be excused because inaccurate word choice is so natural that it will inevitably occur again, and he should not be criticized when the stress of the campaign leads inevitably to mistakes in trivial word choice.

A Bosnian pine living in the highlands of Greece has been shown to be more than 1,075 years, making it the oldest known living tree in Europe. The tree's advanced age was determined by counting its annual rings. Because of its venerable age and where it was found, the scientists dubbed the ancient pine "Adonis," after the Greek god of beauty and desire. The tree lives in a barren alpine landscape at the upper limit of tree line, along with about a dozen other aging members of its species, Pinus heldreichii.

A team of staff, interns and volunteers from my NGO WildlifeDirect put on an ambitious three-day programme of discovery, play and learning for the children.

They met wild animals in the wilderness of Samburu, and talked to rangers and scientists involved in wildlife conservation.

We are not going to build machines any time soon that have feelings like we have feelings: that's consciousness. Robots won't be falling in love with each other (which doesn't mean we are incapable of falling in love with robots). But we have already built machines vast data-processing networks that can know our feelings better than we know them ourselves: that's intelligence. Google the search engine, not the company doesn't have beliefs and desires of its own. It doesn't care what we search for and it won't feel hurt by our behaviour. But it can process our behaviour to know what we want before we know it ourselves. That fact has the potential to change what it means to be human.
Yuval Noah Harari's previous book, the global bestseller Sapiens, laid out the last 75,000 years of human history to remind us that there is nothing special or essential about who we are. We are an accident. Homo sapiens is just one possible way of being human, an evolutionary contingency like every other creature on the planet. That book ended with the thought that the story of homo sapiens could be coming to an end. We are at the height of our power but we may also have reached its limit. Homo Deus makes good on this thought to explain how our unparalleled ability to control the world around us is turning us into something new.
