Artificial neural networks on acid

red-tree-small-long-unsmoothed

Quartz reports: American sci-fi novelist Philip K. Dick once famously asked, Do Androids Dream of Electric Sheep? While he was on the right track, the answer appears to be, no, they don’t. They dream of dog-headed knights atop horses, of camel-birds and pig-snails, and of Dali-esque mutated landscapes.

Google’s image recognition software, which can detect, analyze, and even auto-caption images, uses artificial neural networks to simulate the human brain. In a process they’re calling “inceptionism,” Google engineers sought out to see what these artificial networks “dream” of — what, if anything, do they see in a nondescript image of clouds, for instance? What does a fake brain that’s trained to detect images of dogs see when it’s shown a picture of a knight?

Google trains the software by feeding it millions of images, eventually teaching it to recognize specific objects within a picture. When it’s fed an image, it is asked to emphasize the object in the image that it recognizes. The network is made up of layers — the higher the layer, the more precise the interpretation. Eventually, in the final output layer, the network makes a “decision” as to what’s in the image.

But the networks aren’t restricted to only identifying images. Their training allows them to generate images as well. [Continue reading…]

Pope Francis on the dehumanizing effect of social media and information overload

[W]hen media and the digital world become omnipresent, their influence can stop people from learning how to live wisely, to think deeply and to love generously. In this context, the great sages of the past run the risk of going unheard amid the noise and distractions of an information overload. Efforts need to be made to help these media become sources of new cultural progress for humanity and not a threat to our deepest riches. True wisdom, as the fruit of self-examination, dialogue and generous encounter between persons, is not acquired by a mere accumulation of data which eventually leads to overload and confusion, a sort of mental pollution. Real relationships with others, with all the challenges they entail, now tend to be replaced by a type of internet communication which enables us to choose or eliminate relationships at whim, thus giving rise to a new type of contrived emotion which has more to do with devices and displays than with other people and with nature. Today’s media do enable us to communicate and to share our knowledge and affections. Yet at times they also shield us from direct contact with the pain, the fears and the joys of others and the complexity of their personal experiences. For this reason, we should be concerned that, alongside the exciting possibilities offered by these media, a deep and melancholic dissatisfaction with interpersonal relations, or a harmful sense of isolation, can also arise.

Factory farm nation

Food & Water Watch recently published its report Factory Farm Nation based on an analysis of U.S. Department of Agriculture (USDA) Census of Agriculture data from 1997, 2002, 2007 and 2012 for beef cattle, hogs, dairy cattle, broiler meat chickens and egg-laying operations. These are the report’s key findings:

  • The total number of livestock on the largest factory farms rose by 20 percent between 2002 and 2012. The number of livestock units on factory farms increased from 23.7 million in 2002 to 28.5 million in 2012. “Livestock units” is a way to measure different kinds of animals on the same scale based on their weight — one beef cattle is the equivalent of approximately two-thirds of a dairy cow, eight hogs or four hundred chickens.
  • These factory-farmed livestock produced 369 million tons of manure in 2012, about 13 times as much as the sewage produced by the entire U.S. population. This 13.8 billion cubic feet of manure is enough to fill the Dallas Cowboys stadium 133 times. Unlike sewage produced in cities, manure on factory farms does not undergo any wastewater treatment.
  • The number of dairy cows on factory farms doubled, and the average-sized dairy factory farm increased by half, between 1997 and 2012. The number of dairy cows on factory farms rose 120.9 percent in 2012, the equivalent of adding 550 factory-farmed dairy cows every day for 15 years. The average size of dairy factory farms grew by half (49.1 percent) from 1,114 cows in 1997 to 1,661 in 2012. In nine states — Kansas, Oklahoma, New Mexico, Arizona, Idaho, Texas, Indiana, Missouri and Nevada — the average size was more than 2,000 cows in 2012.
  • The number of beef cattle on feedlots rose 5 percent from 2002 to 2012. Feedlot size grew even as the 2012 drought reduced total cattle numbers. The number of beef cattle on operations with at least 500 head grew from 11.6 million in 2002 to 12.1 million in 2012 — adding about 157 beef cattle every day for 10 years. Texas, Nebraska and Kansas all had more than 2 million beef cattle on feedlots in 2012. The 2012 drought reduced the total number of beef cattle on feedlots nationwide, but the average feedlot size increased by 12.7 percent over five years, from 3,800 in 2007 to more than 4,300 in 2012.
  • The number of hogs on factory farms increased by more than one-third, and the average farm size swelled nearly 70 percent from 1997 to 2012. The number of hogs on factory farms grew by 37.1 percent — from 46.1 million in 1997 to 63.2 million 2012 — the equivalent of adding 3,100 hogs to factory farms every day for the past 15 years. The average size of a hog factory farm increased 68.4 percent, from 3,600 hogs in 1997 to nearly 6,100 in 2012.
  • The number of broiler chickens on factory farms rose nearly 80 percent from 1997 to 2012, to more than 1 billion. The number of broiler chickens raised on factory farms rose 79.9 percent from 583.3 million in 1997 to 1.05 billion in 2012 — about three birds for every person in the United States. The growth in industrial broiler production added 85,000 chickens to factory farms every day over the past 15 years. The average size of U.S. broiler chicken operations rose by 5.9 percent, from 157,000 in 1997 to 166,000 birds in 2012. The average size in California and Nebraska exceeded 500,000 birds in 2012.
  • The number of egg-laying hens on factory farms increased by nearly one quarter from 1997 to 2012, to 269 million. The number of egg-producing layer hens increased 24.8 percent from 215.7 million in 1997 to 269.3 million in 2012. Nearly half (49.3 percent) of the egg-laying hens in 2012 were in the top-five-egg producing states: Iowa, Ohio, Indiana, California and Texas. The average size of egg operations has grown by 74.2 percent over 15 years, rising from 399,000 in 1997 to more than 695,000 in 2012.

How water, paradoxically, creates the land we walk on

Julia Rosen writes: It’s no secret that water shapes the world around us. Rivers etch great canyons into the Earth’s surface, while glaciers reorganize the topography of entire mountain ranges. But water’s influence on the landscape runs much deeper than this: Water explains why we have land in the first place.

You might think of land as the bits of crust that just happen to jut up above sea level, but that’s mostly not the case. Earth’s continents rise above the seas in part because they are actually made of different stuff than the seafloor. Oceanic crust consists of dense, black basalt, which rides low in the mantle — like a wet log in a river — and eventually sinks back into Earth’s interior. But continental crust floats like a cork, thanks to one special rock: granite. If we didn’t have granite to lift the continents up, a vast ocean would cover our entire planet, with barely any land to speak of.

Gritty, gray granite and its rocky relatives dominate the continents. It forms the sheer walls of Yosemite Valley and the chiseled faces of Mount Rushmore (and also gleams from many a kitchen counter and shower stall). If you don’t see granite at the surface, you can bet it’s hiding just a few kilometers below your feet, unless you’re cruising over the middle of the ocean in a boat or plane. But what’s special about granite is that it’s relatively buoyant, for a rock—and that to make it, you need water. [Continue reading…]

The art of attention: John Berger at 88

Philip Maughan writes: In 1967, while working with the Swiss photographer Jean Mohr on A Fortunate Man, a book about a country GP serving a deprived community in the Forest of Dean, Gloucestershire, John Berger began to reconsider what the role of a writer should be. “He does more than treat [his patients] when they are ill,” Berger wrote of John Sassall, a man whose proximity to suffering and poverty deeply affected him (he later committed suicide). The rural doctor assumes a democratic function, in Berger’s eyes, one he describes in consciously literary terms. “He is the objective witness of their lives,” he says. “The clerk of their records.”

The next five years marked a transition in Berger’s life. By 1972, when the groundbreaking art series Ways of Seeing aired on BBC television, Berger had been living on the Continent for over a decade. He won the Booker Prize for his novel G. the same year, announcing to an astonished audience at the black-tie ceremony in London that he would divide his prize money between the Black Panther Party (he denounced Booker McConnell’s historic links with plantations and indentured labour in the Caribbean) and the funding of his next project with Mohr, A Seventh Man, recording the experiences of migrant workers across Europe.

This is the point at which, for some in England, Berger became a more distant figure. He moved from Switzerland to a remote village in the French Alps two years later. “He thinks and feels what the community incoherently knows,” Berger wrote of Sassall, the “fortunate man”. After time spent working on A Seventh Man, those words were just as applicable to the writer himself. It was Berger who had become a “clerk”, collecting stories from the voiceless and dispossessed – peasants, migrants, even animals – a self-effacing role he would continue to occupy for the next 43 years.

The life and work of John Berger represents a challenge. How best to describe the output of a writer whose bibliography, according to Wikipedia, contains ten “novels”, four “plays”, three collections of “poetry” and 33 books labelled “other”?

“A kind of vicarious autobiography and a history of our time as refracted through the prism of art,” is how the writer Geoff Dyer introduced a selection of Berger’s non-fiction in 2001, though the category doesn’t quite fit. “To separate fact and ­imagination, event and feeling, protagonist and narrator, is to stay on dry land and never put to sea,” Berger wrote in 1991 in a manifesto (of sorts) inspired by James Joyce’s Ulysses, a book he first read, in French, at the age of 14.

Everything we thought we knew about the genome is turning out to be wrong

Claire Ainsworth writes: Ask me what a genome is, and I, like many science writers, might mutter about it being the genetic blueprint of a living creature. But then I’ll confess that “blueprint” is a lousy metaphor since it implies that the genome is two-dimensional, prescriptive and unresponsive.

Now two new books about the genome show the limitation of that metaphor for something so intricate, complex, multilayered and dynamic. Both underscore the risks of taking metaphors too literally, not just in undermining popular understanding of science, but also in trammelling scientific enquiry. They are for anyone interested in how new discoveries and controversies will transform our understanding of biology and of ourselves.

John Parrington is an associate professor in molecular and cellular pharmacology at the University of Oxford. In The Deeper Genome, he provides an elegant, accessible account of the profound and unexpected complexities of the human genome, and shows how many ideas developed in the 20th century are being overturned.

Take DNA. It’s no simple linear code, but an intricately wound, 3D structure that coils and uncoils as its genes are read and spliced in myriad ways. Forget genes as discrete, protein-coding “beads on a string”: only a tiny fraction of the genome codes for proteins, and anyway, no one knows exactly what a gene is any more.[Continue reading…]

Why technocracy won’t save the world

Benjamin Cohen writes: In a 2014 New Yorker profile of twenty-five year old entrepreneur Rob Rhinehart, Lizzie Widdicombe explained the millenial’s motives for inventing a new caloric infusion named for the 1973 film. Rhinehart thought that “food was an inefficient way of getting what he needed to survive.” He “began to resent the fact that he had to eat at all.” It was becoming too problematic for him to invest the effort in food shopping, preparation, or even, apparently, consumption. For the lifehacker, these were the wrong kind of disruptive. Widdicombe resisted editorializing on the shocking arrogance of the view that food was a hindrance to life. But I won’t. When a Bay Area twenty-something understands food as an obstacle to daily life, that person conceives of the environment as a constraint on rather than the basis of living. The dream of efficiency and the view that food is but a calorie delivery vehicle is all too familiar as resting on assumptions of a technocratic worldview.

I question whether anything is best pursued by technocratic means, let alone environmentalism; the political character of technocracy is ethically tenuous for the governance of people, not to mention nature. Technocratic thinking is based on logic of dehumanized values. It’s pinned to strictly technical criteria measured by disembodied quantitative metrics — efficiency, speed, yield, productivity, for example. Anything non-technical is not of significance: if it can’t be stated as a technical problem then it isn’t a problem at all. Values beyond that of a thin and narrow register — consider empowerment, dignity, justice, fulfillment, nourishment, honor, harmony — have no place in such a discussion because they’re too difficult to shoehorn into technical metrics. As for environmental virtues, good luck. Biodiversity, environmental knowledge, or the organic tenets of sustainable ecosystems find little space in technocratic pursuits. [Continue reading…]

How technology is damaging our brains

The New York Times reports: When one of the most important e-mail messages of his life landed in his in-box a few years ago, Kord Campbell overlooked it.

Not just for a day or two, but 12 days. He finally saw it while sifting through old messages: a big company wanted to buy his Internet start-up.

“I stood up from my desk and said, ‘Oh my God, oh my God, oh my God,’ ” Mr. Campbell said. “It’s kind of hard to miss an e-mail like that, but I did.”

The message had slipped by him amid an electronic flood: two computer screens alive with e-mail, instant messages, online chats, a Web browser and the computer code he was writing.

While he managed to salvage the $1.3 million deal after apologizing to his suitor, Mr. Campbell continues to struggle with the effects of the deluge of data. Even after he unplugs, he craves the stimulation he gets from his electronic gadgets. He forgets things like dinner plans, and he has trouble focusing on his family.

His wife, Brenda, complains, “It seems like he can no longer be fully in the moment.”

This is your brain on computers.

Scientists say juggling e-mail, phone calls and other incoming information can change how people think and behave. They say our ability to focus is being undermined by bursts of information.

These play to a primitive impulse to respond to immediate opportunities and threats. The stimulation provokes excitement — a dopamine squirt — that researchers say can be addictive. In its absence, people feel bored.

The resulting distractions can have deadly consequences, as when cellphone-wielding drivers and train engineers cause wrecks. And for millions of people like Mr. Campbell, these urges can inflict nicks and cuts on creativity and deep thought, interrupting work and family life.

While many people say multitasking makes them more productive, research shows otherwise. Heavy multitaskers actually have more trouble focusing and shutting out irrelevant information, scientists say, and they experience more stress.

And scientists are discovering that even after the multitasking ends, fractured thinking and lack of focus persist. In other words, this is also your brain off computers. [Continue reading…]

DNA deciphers roots of modern Europeans

Carl Zimmer writes: For centuries, archaeologists have reconstructed the early history of Europe by digging up ancient settlements and examining the items that their inhabitants left behind. More recently, researchers have been scrutinizing something even more revealing than pots, chariots and swords: DNA.

On Wednesday in the journal Nature, two teams of scientists — one based at the University of Copenhagen and one based at Harvard University — presented the largest studies to date of ancient European DNA, extracted from 170 skeletons found in countries from Spain to Russia. Both studies indicate that today’s Europeans descend from three groups who moved into Europe at different stages of history.

The first were hunter-gatherers who arrived some 45,000 years ago in Europe. Then came farmers who arrived from the Near East about 8,000 years ago.

Finally, a group of nomadic sheepherders from western Russia called the Yamnaya arrived about 4,500 years ago. The authors of the new studies also suggest that the Yamnaya language may have given rise to many of the languages spoken in Europe today. [Continue reading…]

Even atheists intuitively believe in a creator

sunflower

Tom Jacobs writes: Since the discoveries of Darwin, evidence has gradually mounted refuting the notion that the natural world is the product of a deity or other outside designer. Yet this idea remains firmly lodged in the human brain.

Just how firmly is the subject of newly published research, which finds even self-proclaimed atheists instinctively think of natural phenomena as being purposefully created.

The findings “suggest that there is a deeply rooted natural tendency to view nature as designed,” writes a research team led by Elisa Järnfelt of Newman University. They also provide evidence that, in the researchers’ words, “religious non-belief is cognitively effortful.” [Continue reading…]
