Savannah elephants have declined by at least 60% over the last half-century.

“Africa’s elephants play key roles in ecosystems, economies and in our collective imagination all over the world,”

The report did include some good news. Anti-poaching programs in some regions of Gabon and the Republic of the Congo have helped forest elephant numbers stabilize.

The pandering can be insidious, too. The Perot Museum of Nature and Science in Dallas, which treats visitors to a virtual ride down a hydraulic fracturing well, recently made headlines for avoiding explicit references to climate change. Other museums omit scientific information on evolution. “We don’t need people to come in here and reject us,”

Even the best natural history museums have been obliged to reduce their scientific staff in the face of government cutbacks and the decline in donations following the 2008 economic crash. They still have their collections, and their public still comes through the door. But they no longer employ enough scientists to interpret those collections adequately for visitors or the world at large. Hence the journal Nature last year characterized natural history collections as “the endangered dead.”

these collections are less about the past than about our world and how it is changing. Sediment cores like the ones at the Illinois State Museum, for instance, may not sound terribly important, but the pollen in them reveals how past climates changed, what species lived and died as a result, and thus how our own future may be rapidly unfolding.

Natural history museums are so focused on the future that they have for centuries routinely preserved such specimens to answer questions they didn’t yet know how to ask, requiring methodologies that had not yet been invented, to make discoveries that would have been, for the original collectors, inconceivable.

THE people who first put gigantic mammoth and mastodon specimens in museums, for instance, did so mainly out of dumb wonderment. But those specimens soon led to the stunning 18th-century recognition that parts of God’s creation could become extinct. The heretical idea of extinction then became an essential preamble to Darwin, whose understanding of evolution by natural selection depended in turn on the detailed study of barnacle specimens collected and preserved over long periods and for no particular reason. Today, those same specimens continue to answer new questions with the help of genome sequencing, CT scans, stable isotope analysis and other technologies.

These museums also play a critical role in protecting what’s left of the natural world, in part because they often combine biological and botanical knowledge with broad anthropological experience.

“You have no nationality. You are scientists. You speak for nature.” Just since 1999, according to the Field Museum, inventories by its curators and their collaborators have been a key factor in the protection of 26.6 million acres of wilderness, mainly in the headwaters of the Amazon.

It may be optimistic to say that natural history museums have saved the world. It may even be too late for that. But they provide one other critical service that can save us, and our sense of wonder: Almost everybody in this country — even children in Denver who have never been to the Rocky Mountains, or people in San Francisco who have never walked on a Pacific Ocean beach — goes to a natural history museum at some point in his life, and these visits influence us in deep and unpredictable ways.

we dimly begin to understand the passage of time and cultures, and how our own species fits amid millions of others. We start to understand the strangeness and splendor of the only planet where we will ever have the great pleasure of living.

Even by the middle of the 19th Century, only 10% of adults knew how to write, and there are only about 140 scripts in use today. 

“Endangered alphabets and scripts just haven’t been brought to people’s attention in the same way as languages,”

By their very artificiality, alphabets arguably say more about a culture than mere language. That starts with the characters themselves

Writing can tell us about a culture in other ways, too. Because they live in the thick forests of the Philippines, users of Hanunuo have traditionally inscribed messages into bows of bamboo. Different fonts depend on the way that scribes wield the knife.

Not that scripts are simply a means of communication. Some burrow right into the values of the people who use them, and not just because they often record sacred prayers or ancient remedies.

Some alphabet devotees are taking these lessons so seriously that they invent whole new scripts.

One of the most spectacular examples comes from a pair of Guinean brothers, Abdoulaye and Ibrahima Barry. Tired of squashing their native Fulani tongue into the French (Latin) or Arabic alphabets, neither of which could accurately represent the range of Fulani sounds, they developed something better.

The result was Adlam, named after the first four letters of the alphabet. 

Just as the loss of a species decreases the richness of an ecosystem, the addition of new animals could achieve the opposite effect.

National Geographic Society hosted a larger conference to debate the scientific and ethical questions raised by the prospect of “de-extinction.

“De-extinction went from concept to potential reality right before our eyes,

less scientific, if more persuasive, argument was advanced by the ethicist Hank Greely and the law professor Jacob Sherkow, both of Stanford. De-extinction should be pursued, they argued in a paper published in Science, because it would be really

“This may be the biggest attraction and possibly the biggest benefit of de-extinction. It would surely be very cool to see a living woolly mammoth.”

They will replace chunks of band-tailed-pigeon DNA with synthesized chunks of passenger-pigeon DNA, until the cell’s genome matches their working passenger-pigeon genome.

Scientists predict that changes made by human beings to the composition of the atmosphere could kill off a quarter of the planet’s mammal species, a fifth of its reptiles and a sixth of its birds by 2050

This cloning method, called somatic cell nuclear transfer, can be used only on species for which we have cellular material.

There is a shortcut. The genome of a closely related species will have a high proportion of identical DNA, so it can serve as a blueprint, or “scaffold.”

By comparing the fragments of passenger-pigeon DNA with the genomes of similar species, researchers can assemble an approximation of an actual passenger-pigeon genome.

As with any translation, there may be errors of grammar, clumsy phrases and perhaps a few missing passages, but the book will be legible. It should, at least, tell a good story.

the genome will have to be inscribed into a living cell.

“We’ve framed it in terms of conservation,”

MAGE (Multiplex Automated Genome Engineering). MAGE is nicknamed the “evolution machine” because it can introduce the equivalent of millions of years of genetic mutations within minutes

Developmental and behavioral biologists would take over, just in time to answer some difficult questions. Chicks imitate their parents’ behavior. How do you raise a passenger pigeon without parents of its own species? And how do you train band-tailed pigeons to nurture the strange spawn that emerge from their eggs; chicks that, to them, might seem monstrous: an avian Rosemary’s Baby?

For endangered species with tiny populations, scientists would introduce genetic diversity to offset inbreeding.

They will try to alter the birds’ diets, migration habits and environment. The behavior of each subsequent generation will more closely resemble that of their genetic cousins.

For species threatened by contagion, an effort would be made to fortify their DNA with genes that make them disease-resistant

The scientific term for this type of genetic intervention is “facilitated adaptation.”

This optimistic, soft-focus fantasy of de-extinction, while thrilling to Ben Novak, is disturbing to many conservation biologists, who consider it a threat to their entire discipline and even to the environmental movement.

The first question posed by conservationists addresses the logic of bringing back an animal whose native habitat has disappeared. Why go through all the trouble just to have the animal go extinct all over again?

There is also anxiety about disease

“If you recreate a species genetically and release it, and that genotype is based on a bird from a 100-year-old environment, you probably will increase risk.”

“There’s always this fear that somehow, if we do it, we’re going to accidentally make something horrible, because only nature can really do it right. But nature is totally random. Nature makes monsters. Nature makes threats. Many of the things that are most threatening to us are a product of nature. Revive & Restore is not going to tip the balance in any way.”

De-extinction also poses a rhetorical threat to conservation biologists. The specter of extinction has been the conservation movement’s most powerful argument. What if extinction begins to be seen as a temporary inconvenience?

De-extinction suggests that we can technofix our way out of environmental issues generally, and that’s very, very bad.

How will we decide which species to resurrect?

Philip Seddon recently published a 10-point checklist to determine the suitability of any species for revival, taking into account causes of its extinction, possible threats it might face upon resurrection and man’s ability to destroy the species “in the event of unacceptable ecological or socioeconomic impacts.”

But the most visceral argument against de-extinction is animal cruelty.

“Is it fair to do this to these animals?” Shapiro asked. “Is ‘because we feel guilty’ a good-enough reason?” Stewart Brand made a utilitarian counterargument: “We’re going to go through some suffering, because you try a lot of times, and you get ones that don’t take. On the other hand, if you can bring bucardos back, then how many would get to live that would not have gotten to live?”

In “How to Permit Your Mammoth,” published in The Stanford Environmental Law Journal, Norman F. Carlin asks whether revived species should be protected by the Endangered Species Act or regulated as a genetically modified organism.

He concludes that revived species, “as products of human ingenuity,” should be eligible for patenting.

The term “de-extinction” is misleading. Passenger pigeons will not rise from the grave

Our understanding of the passenger pigeon’s behavior derives entirely from historical accounts.

There is no authoritative definition of “species.” The most widely accepted definition describes a group of organisms that can procreate with one another and produce fertile offspring, but there are many exceptions.

Theseus’ ship, therefore, “became a standing example among the philosophers . . . one side holding that the ship remained the same, and the other contending that it was not the same.”

What is coming will go well beyond the resurrection of extinct species. For millenniums, we have customized our environment, our vegetables and our animals, through breeding, fertilization and pollination. Synthetic biology offers far more sophisticated tools. The creation of novel organisms, like new animals, plants and bacteria, will transform human medicine, agriculture, energy production and much else.

More than two decades ago, a study of 295 skulls in museums found “enormous differences” between the two types of elephants, he said. In life, forest elephants have smaller bodies, rounder ears and straighter tusks than savanna elephants.

Elephants being killed for their ivory tusks isn’t a new problem, and neither is the habitat loss they face.

Savanna elephants are “thriving,”

“At the moment we are getting to the minds of the people,” Dr. Okita said. “But we need to get to the hearts.”

The average savanna elephant mother gives birth at 25 years; forest elephant moms are 31 on average. Because the earliest surveys researchers could find were from the 1960s and 1970s, they could peer back only two generations for savanna elephants, and a single generation for forest elephants.

“The forest elephants, in most cases, have been largely ignored,” he said. Grouping the two elephants together probably masked just how bad things were for the forest elephant, he said.

that domestication probably began around 20,000 years ago.

much more diverse genetically than modern dogs.

All European dogs appear to have descended from one group of ancient European dogs, and the great modern diversity of dog shapes and sizes indicates an emphasis by breeders on certain very powerful genes.

Modern wolves, however, do show the incorporation of some dog DNA.

The extraordinarily rich amount of information gathered from the 27 genomes provided many new perspectives on dog domestication and their association with humans.

even while they were sometimes breeding with wolves, no new wolf DNA entered their genomes.

Pigs can be a little wild but “if you’re a dog and you’ve got a little bit of wolf in you, that’s not a good thing and those things get knocked on the head very quickly or run away or disappear but they don’t get integrated into the dog population.”

But then there was the sudden loss of diversity in dogs starting around 4,000 years ago.

The exact where and when of dog domestication remain unclear, and will never be pinned down to the kind of moment in time that dog owners like to imagine, but, in terms of a period of time and geographic area, Dr. Larson said, “We’re getting closer.”

Clive Wynne, a psychologist specializing in dog behavior, contends that what makes your furry friend special is not its intellect but its ability to bond with you. And not just with you. The dog’s ability to bond across species — with sheep, goats, even (horrors!) cats

Thirteen species of salmon and steelhead trout are considered threatened or endangered in the Northwest’s Columbia basin region

The fish are a keystone food source for other species, and an endangered population of orcas may be starving for lack of enough wild salmon to eat. Many scientists favor removing dams on some rivers to save the orcas and the fish. But the idea faces resistance from government agencies that manage the rivers.

A video of salmon traveling through a long tube went viral in 2019. You probably watched it. But the Whooshh cannon — its actual name — is a serious tool that conservationists are testing not only to help fish migrate, but to contain invasive carp that foul North American waterways.

A New and Improved Table could come in handy: As more superheavy elements are discovered, their behaviors could challenge the integrity of Mendeleev’s memorable chart.

Is this all sounding rather familiar now? Does it remind you of something?

it quickly became clear that the GamerGate movement was a mess – an undefined mission to Make Video Games Great Again via undecided means.

fter all, the culture war that began in games now has a senior representative in The White House. As a founder member and former executive chair of Brietbart News, Steve Bannon had a hand in creating media monster Milo Yiannopoulos, who built his fame and Twitter following by supporting and cheerleading Gamergate. This hashtag was the canary in the coalmine, and we ignored it.

Gamergate was an online movement that effectively began because a man wanted to punish his ex girlfriend. Its most notable achievement was harassing a large number of progressive figures - mostly women – to the point where they felt unsafe or considered leaving the industry

The similarities between Gamergate and the far-right online movement, the “alt-right”, are huge, startling and in no way a coincidence

These figures gave Gamergate a new sense of direction – generalising the rhetoric: this was now a wider war between “Social Justice Warriors” (SJWs) and everyday, normal, decent people. Games were simply the tip of the iceberg – progressive values, went the argument, were destroying everything

In 2016, new wave conservative media outlets like Breitbart have gained trust with their audience by painting traditional news sources as snooty and aloof. In 2014, video game YouTube stars, seeking to appear in touch with online gaming communities, unscrupulously proclaimed that traditional old-media sources were corrupt. Everything we’re seeing now, had its precedent two years ago.

With 2014’s Gamergate, Breitbart seized the opportunity to harness the pre-existing ignorance and anger among disaffected young white dudes. With Trump’s movement in 2016, the outlet was effectively running his campaign: Steve Bannon took leave of his role at the company in August 2016 when he was hired as chief executive of Trump’s presidential campaign

young men converted via 2014’s Gamergate, are being more widely courted now. By leveraging distrust and resentment towards women, minorities and progressives, many of Gamergate’s most prominent voices – characters like Mike Cernovich, Adam Baldwin, and Milo Yiannopoulos – drew power and influence from its chaos

no one in the movement was willing to be associated with the abuse being carried out in its name. Prominent supporters on Twitter, in subreddits and on forums like 8Chan, developed a range of pernicious rhetorical devices and defences to distance themselves from threats to women and minorities in the industry: the targets were lying or exaggerating, they were too precious; a language of dismissal and belittlement was formed against them. Safe spaces, snowflakes, unicorns, cry bullies. Even when abuse was proven, the usual response was that people on their side were being abused too. These techniques, forged in Gamergate, have become the standard toolset of far-right voices online

The majority of people who voted for Trump will never take responsibility for his racist, totalitarian policies, but they’ll provide useful cover and legitimacy for those who demand the very worst from the President Elect. Trump himself may have disavowed the “alt-right”, but his rhetoric has led to them feeling legitimised. As with Gamergate, the press risks being manipulated into a position where it has to tread a respectful middle ground that doesn’t really exist.

Using 4chan (and then the more sympathetic offshoot 8Chan) to plan their subversions and attacks made Gamergate a terribly sloppy operation, leaving a trail of evidence that made it quite clear the whole thing was purposefully, plainly nasty. But the video game industry didn’t have the spine to react, and allowed the movement to coagulate – forming a mass of spiteful disappointment that Breitbart was only more than happy to coddle

Historically, that seems to be Breitbart’s trick - strongly represent a single issue in order to earn trust, and then gradually indoctrinate to suit wider purposes. With Gamergate, they purposefully went fishing for anti-feminists. 2016’s batch of fresh converts – the white extremists – came from enticing conspiracy theories about the global neoliberal elite secretly controlling the world.

The greatest strength of Gamergate, though, was that it actually appeared to represent many left-leaning ideals: stamping out corruption in the press, pushing for better ethical practices, battling for openness.

There are similarities here with many who support Trump because of his promises to put an end to broken neo-liberalism, to “drain the swamp” of establishment corruption. Many left-leaning supporters of Gamergate sought to intellectualise their alignment with the hashtag, adopting familiar and acceptable labels of dissent – identifying as libertarian, egalitarian, humanist.

At best they unknowingly facilitated abuse, defending their own freedom of expression while those who actually needed support were threatened and attacked.

Genuine discussions over criticism, identity and censorship were paralysed and waylaid by Twitter voices obsessed with rhetorical fallacies and pedantic debating practices. While the core of these movements make people’s lives hell, the outer shell – knowingly or otherwise – protect abusers by insisting that the real problem is that you don’t want to talk, or won’t provide the ever-shifting evidence they politely require.

In 2017, the tactics used to discredit progressive game critics and developers will be used to discredit Trump and Bannon’s critics. There will be gaslighting, there will be attempts to make victims look as though they are losing their grip on reality, to the point that they gradually even start to believe it. The “post-truth” reality is not simply an accident – it is a concerted assault on the rational psyche.

The strangest aspect of Gamergate is that it consistently didn’t make any sense: people chose to align with it, and yet refused responsibility. It was constantly demanded that we debate the issues, but explanations and facts were treated with scorn. Attempts to find common ground saw the specifics of the demands being shifted: we want you to listen to us; we want you to change your ways; we want you to close your publication down. This movement that ostensibly wanted to protect free speech from cry bully SJWs simultaneously did what it could to endanger sites it disagreed with, encouraging advertisers to abandon support for media outlets that published stories critical of the hashtag. The petulance of that movement is disturbingly echoed in Trump’s own Twitter feed.

Looking back, Gamergate really only made sense in one way: as an exemplar of what Umberto Eco called “eternal fascism”, a form of extremism he believed could flourish at any point in, in any place – a fascism that would extol traditional values, rally against diversity and cultural critics, believe in the value of action above thought and encourage a distrust of intellectuals or experts – a fascism built on frustration and machismo. The requirement of this formless fascism would – above all else – be to remain in an endless state of conflict, a fight against a foe who must always be portrayed as impossibly strong and laughably weak

2016 has presented us with a world in which our reality is being wilfully manipulated. Fake news, divisive algorithms, misleading social media campaigns.

The same voices moved into other geek communities, especially comics, where Marvel and DC were criticised for progressive storylines and decisions. They moved into science fiction with the controversy over the Hugo awards. They moved into cinema with the revolting kickback against the all-female Ghostbusters reboot.

Perhaps the true lesson of Gamergate was that the media is culturally unequipped to deal with the forces actively driving these online movements. The situation was horrifying enough two years ago, it is many times more dangerous now.

This corruption map of France seems to be a local initiative. Similar maps of other countries would make for equally compelling reading. Except of course the corruption maps of Somalia, South Sudan and North Korea – they would be totally blank.

Numerous environmental statutes mandate that government agencies consider “the best available science” when making decisions. And agencies routinely consult with scientific experts to fullfill such mandates.

Such provisions work reasonably well when science offers clear and simple, black-and-white answers. But when there is uncertainty, is the expectation of scientific objectivity realistic?

To gain insight into what role bias may play in listing decisions, we surveyed a group of grizzly bear researchers. We found that experts’ judgments were associated with a number of factors outside the “best commercial and scientific data,” including their professional affiliations and social norms. Furthermore, we found that while there is no consensus in the scientific community regarding the threats to grizzly bears, the majority of scientists support continued listing.

some said they are already witnessing deficiencies in young peoples’ abilities to focus their attention, be patient and think deeply. Some experts expressed concerns that trends are leading to a future in which most people become shallow consumers of information, endangering society."

Many of the respondents in this survey predict that Gen AO will exhibit a thirst for instant gratification and quick fixes and a lack of patience and deep-thinking ability due to what one referred to as “fast-twitch wiring.”

“The replacement of memorization by analysis will be the biggest boon to society since the coming of mass literacy in the late 19th to early 20th century.” — Paul Jones, University of North Carolina-Chapel Hill

“Teens find distraction while working, distraction while driving, distraction while talking to the neighbours. Parents and teachers will have to invest major time and efforts into solving this issue – silence zones, time-out zones, meditation classes without mobile, lessons in ignoring people.”

“Society is becoming conditioned into dependence on technology in ways that, if that technology suddenly disappears or breaks down, will render people functionally useless. What does that mean for individual and social resiliency?

“Short attention spans resulting from quick interactions will be detrimental to focusing on the harder problems and we will probably see a stagnation in many areas: technology, even social venues such as literature. The people who will strive and lead the charge will be the ones able to disconnect themselves to focus.”

“The underlying issue is that they will become dependent on the Internet in order to solve problems and conduct their personal, professional, and civic lives. Thus centralized powers that can control access to the Internet will be able to significantly control future generations. It will be much as in Orwell's 1984, where control was achieved by using language to shape and limit thought, so future regimes may use control of access to the Internet to shape and limit thought.”

“Increasingly, teens and young adults rely on the first bit of information they find on a topic, assuming that they have found the ‘right’ answer, rather than using context and vetting/questioning the sources of information to gain a holistic view of a topic.”

“Parents and kids will spend less time developing meaningful and bonded relationships in deference to the pursuit and processing of more and more segmented information competing for space in their heads, slowly changing their connection to humanity.”

“It’s simply not possible to discuss, let alone form societal consensus around major problems without lengthy, messy conversations about those problems. A generation that expects to spend 140 or fewer characters on a topic and rejects nuance is incapable of tackling these problems.”

Last year, researchers at Stanford University drew headlines with the results of a functional magnetic resonance imaging (or fMRI) experiment showing that different regions of the brain were activated when subjects switched from reading Jane Austen’s “Mansfield Park” for pleasure to reading it analytically

And this fall, a study out of the New School for Social Research showed that readers of literary fiction scored higher on tests of empathy than readers of commercial fiction, a finding greeted with satisfied told-you-sos from many readers and writers alike.

In overdeveloping the capacity to show how texts, institutions or people fail to accomplish what they set out to do, we may be depriving students of the chance to learn as much as possible from what they study.

As debunkers, they contribute to a cultural climate that has little tolerance for finding or making meaning — a culture whose intellectuals and cultural commentators get “liked” by showing that somebody else just can’t be believed.

Liberal education in America has long been characterized by the intertwining of two traditions: of critical inquiry in pursuit of truth and exuberant performance in pursuit of excellence. In the last half-century, though, emphasis on inquiry has become dominant, and it has often been reduced to the ability to expose error and undermine belief.

fetishizing disbelief as a sign of intelligence has contributed to depleting our cultural resources. Creative work, in whatever field, depends upon commitment, the energy of participation and the ability to become absorbed in works of literature, art and science. That type of absorption is becoming an endangered species of cultural life, as our nonstop, increasingly fractured technological existence wears down our receptive capacities.

Liberal learning depends on absorption in compelling work. It is a way to open ourselves to the various forms of life in which we might actively participate. When we learn to read or look or listen intensively, we are, at least temporarily, overcoming our own blindness by trying to understand an experience from another’s point of view.

we are learning to activate potential, and often to instigate new possibilities.

Liberal education must not limit itself to critical thinking and problem solving; it must also foster openness, participation and opportunity. It should be designed to take us beyond the campus to a life of ongoing, pragmatic learning that finds inspiration in unexpected sources, and increases our capacity to understand and contribute to the world

"We believe the tools we are developing will exponentially increase the involvement of the Indigenous people whose languages are threatened, without the need for difficult-to-attain levels of computer literacy,"

Until now endangered aboriginal languages were recorded in the presence of a linguist and selected native speakers with recording equipment

indigenous people whose languages are threatened can record and upload languages at their own pace and at times which suit them, he says, without requiring the presence of a specialist holding a microphone

"The ability provided by the tools we are developing to easily create, record and share language, images, and video, at the same time as building sustainable databases for future use, involves and empowers speakers of indigenous languages in a way which has not been possible before."

“I’ve been a programmer for 13 years, and I’ve always been one of the only women and queer people in the room. I’ve been harassed, I’ve had people make suggestive comments to me, I’ve had people basically dismiss my expertise. I’ve gotten rape and death threats just for speaking out about this stuff.”

“We see these stories, ‘Why aren’t there more women in computer science and engineering?’ and there’s all these complicated answers like, ‘School advisers don’t have them take math and physics,’ and it’s probably true,” said Lauren Weinstein, a man who has spent his four-decade career in tech working mostly with other men, and is currently a consultant for Google.“But I think there’s probably a simpler reason,” he said, “which is these guys are just jerks, and women know it.”

once programming gained prestige, women were pushed out. Over the decades, the share of women in computing has continued to decline. In 2012, just 18 percent of computer-science college graduates were women, down from 37 percent in 1985, according to the National Center for Women & Information Technology.

Some 1.2 million computing jobs will be available in 2022, yet United States universities are producing only 39 percent of the graduates needed to fill them, the N.C.W.I.T. estimates.

Twenty percent of software developers are women, according to the Labor Department, and fewer than 6 percent of engineers are black or Hispanic. Comparatively, 56 percent of people in business and financial-operations jobs are women, as are 36 percent of physicians and surgeons and one-third of lawyers.

an engineer at Pinterest has collected data from people at 133 start-ups and found that an average of 12 percent of the engineers are women.

“It makes a hostile environment for me,” she said. “But I don’t want to raise my hand and call negative attention toward myself, and become the woman who is the problem — ‘that woman.’ In start-up culture they protect their own tribe, so by putting my hand up, I’m saying I’m an ‘other,’ I shouldn’t be there, so for me that’s an economic threat.”

“Many women have come to me and said they basically have had to hide on the Net now,” said Mr. Weinstein, who works on issues of identity and anonymity online. “They use male names, they don’t put their real photos up, because they are immediately targeted and harassed.”

“It’s a boys’ club, and you have to try to get into it, and they’re trying as hard as they can to prove you can’t,” said Ephrat Bitton, the director of algorithms at FutureAdvisor, an online investment start-up that she says has a better culture because almost half the engineers are women.

Writing code is a high-pressure job with little room for error, as are many jobs. But coding can be stressful in a different way, women interviewed for this article said, because code reviews — peer reviews to spot mistakes in software — can quickly devolve.

“Code reviews are brutal — ‘Mine is better than yours, I see flaws in yours’ — and they should be, for the creation of good software,” said Ellen Ullman, a software engineer and author. “I think when you add a drop of women into it, it just exacerbates the problem, because here’s a kind of foreigner.”

But some women argue that these kinds of initiatives are unhelpful.“My general issue with the coverage of women in tech is that women in the technology press are talked about in the context of being women, and men are talked about in the context of being in technology,” said a technical woman who would speak only on condition of anonymity because she did not want to be part of an article about women in tech.

There is indeed a deep and well-established kinship between science and the left, one that reaches to the earliest days of modern science and politics and has grown stronger with time. Even though they go astray in caricaturing conservatives as anti-science Luddites, American liberals and progressives are not mistaken to think of themselves as the party of science. They do, however, tend to focus on only a few elements and consequences of that connection, and to look past some deep and complicated problems in the much-valued relationship. The profound ties that bind science and the left can teach us a great deal about both.

It is not unfair to suggest that the right emerged in response to the left, as the anti-traditional theory and practice of the French Revolution provoked a powerful reaction in defense of a political order built to suit human nature and tested and tried through generations of practice and reform.

The left, however, did not emerge in response to the right. It emerged in response to a new set of ideas and intellectual possibilities that burst onto the European scene in the seventeenth and eighteenth centuries—ideas and possibilities that we now think of as modern scientific thought.

Both as action and as knowledge, then, science has been a source of inspiration for progressives and for liberals, and its advancement has been one of their great causes. That does not mean that science captures all there is to know about the left. Far from it. The left has always had a deeply romantic and even anti-rationalist side too, reaching back almost as far as its scientism. But in its basic view of knowledge, power, nature, and man, the left owes much to science. And in the causes it chooses to advance in our time, it often looks to scientific thought and practice for guidance. In its most essential disagreements with the right—in particular, about tradition—the vision defended by the left is also a vision of scientific progress.

Not all environmentalism indulges in such anti-humanism, to be sure. But in all of its forms, the environmentalist ethic calls for a science of beholding nature, not of mastering it. Far from viewing nature as the oppressor, this new vision sees nature as a precious, vulnerable, and almost benevolent passive environment, held in careful balance, and under siege by human action and human power. This view of nature calls for human restraint and humility—and for diminished expectations of human power and potential.The environmental movement is, in this sense, not a natural fit for the progressive and forward-looking mentality of the left. Indeed, in many important respects environmentalism is deeply conservative. It takes no great feat of logic to show that conservation is conservative, of course, but the conservatism of the environmental movement runs far deeper than that. The movement seeks to preserve a given balance which we did not create, are not capable of fully understanding, and should not delude ourselves into imagining we can much improve—in other words, its attitude toward nature is much like the attitude of conservatism toward society.

Moreover, contemporary environmentalism is deeply moralistic. It speaks of duties and responsibilities, of curbing arrogance and vice.

But whatever the reason, environmentalism, and with it a worldview deeply at odds with that behind the scientific enterprise, has come to play a pivotal role in the thinking of the left.

The American left seeks to be both the party of science and the party of equality. But in the coming years, as the biotechnology revolution progresses, it will increasingly be forced to confront the powerful tension between these two aspirations.

To choose well, the American left will need first to understand that a choice is even needed at all—that this tension exists between the ideals of progressives, and the ideology of science.

The answer, as ever, is moderation. The American left, like the American right, must understand science as a human endeavor with ethical purposes and practical limits, one which must be kept within certain boundaries by a self-governing people. In failing to observe and to enforce those boundaries, the left threatens its own greatest assets, and exacerbates tensions at the foundations of American political life. To make the most of the benefits scientific advancement can bring us, we must be alert to the risks it may pose. That awareness is endangered by the closing of the gap between science and the left—and the danger is greatest for the left itself.

• The threatening power of the time—Nazi Germany then, the Islamists' Iran now—is a force of unalloyed evil whose very existence threatens decent life everywhere.

• That emerging power cannot be reasoned or bargained with but must ultimately be stopped and broken

• "Compromisers" are in fact appeasers who are deluding themselves about these realities

• The appeasers' blindness endangers people all around the world but poses an especially intolerable threat to Jews

• As a result of all these factors, no deal with such an implacable enemy is preferable to an inevitably flawed and Munich-like false-hope deal.

Also, and crucially, it means that the most obvious criticism of the speech—what's Netanyahu's plan for getting Iran to agree?—is irrelevant. What was the Allies' "plan" for getting Hitler to agree? The plan was to destroy his regime.

If, on the other hand, you think that the contrasts with 1938 are more striking than the similarities, you see things differently. As a brief reminder of the contrasts: the Germany of 1938 was much richer and more powerful than the Iran of today. Germany was rapidly expansionist; Iran, despite its terrorist work through proxies, has not been. The Nazi leaders had engulfed the world in war less than a decade after taking power. Iran's leaders, oppressive and destructive, have not shown similar suicidal recklessness. European Jews of 1938 were stateless, unarmed, and vulnerable. Modern Israel is a powerful, nuclear-armed force. Moreover, the world after the first wartime use of nuclear weapons, of course by the United States, is different from the world before that point.

Here's what I understand the more clearly after these past few weeks' drama over Prime Minister Netanyahu's speech. These differences in historic model are deep and powerful, and people with one model in mind are not going to convince people with the other mental picture.

It’s true there are “extremists on both sides,” but as this Wonk Blog post showed, the percentage of non-centrist Republicans skyrocketed from under 10 percent in the Ford years (less than Democrats) to almost 90 percent today, while the Democratic percentage has stayed basically flat [chart].

What’s more, in the last session (2013-2014), the data shows that 147 House Republicans — more than half the caucus — were more ideologically extreme than the most extreme Democrat in the House. There is simply no comparison between the two partie

But it’s a fact that “balanced” journalism has to ignore. To admit that the political world isn’t balanced would shake their whole belief system to its core. And yet, the shaking seems to have begun

The GOP’s strategic logic is simple and straightforward: If the media is going to split the difference between what Democrats and Republicans say, then if Republicans simply double their demands, suddenly the media, embracing the “sensible center,” will now articulate the old GOP position as the “sensible center,” the “common sense” place to be

Their stubborn adherence to a false balance narrative has, ironically, become an integral part of the GOP’s relentless rightward push. By talking about “government dysfunction” instead of “Republican obstruction,” the media actively helps the most extreme anti-government Republicans thwart any efforts at competent governance and it helps promote their “government is horrible” worldview

There was once a penalty for becoming too politically extreme: one’s actions would be characterized as unrealistic, destructive, heedless of past experience, etc. Sometimes this was justified, sometimes not (as with the Civil Rights movement). But right or wrong, this media practice inhibited radical movements in either direction.

For quite some time now, however, conservative Republicans have realized that by moving right and attacking the media for any criticism, they can turn the media into a tacit ally, forcing them to treat preposterous claims as serious ideas, or even proven facts

Norm’s response underscores the reality of asymmetric polarization, which the mainstream media and most good government groups have avoided discussing — at great costs to the country

Thus, when they were planning to force a government shutdown, a key part of their strategy was spinning the media with a preposterous argument that it was the Democrats who were shutting down the government, even though, as the New York Times reported, the shutdown plan traced back to a meeting early in President Obama’s second term, led by former Attorney General Edwin R. Meese.

What’s more, once the media plays along, it’s a trick that can be used over and over again. One can keep moving farther and farther right indefinitely, pulling the “objective” media along for the ride, every step of the way. (Conservatives even developed an operational model to describe the process, known as the “Overton Window,” explained by a conservative activist here.)

The basis for all this is a cultural illusion that the “nonpartisan” media is somehow objective, philosophically in tune with science.

historically, this is far from true. Up until the late 19th century, American journalism was quite partisan, serving substantial “niche” audiences, sustained by subscriptions.

hen advertising exploded as a revenue source in the early 20th century, a new journalistic model emerged, trying to appeal across parties, while taking care not to anger large advertisers. The broader story is well told by Paul Starr in “The Creation of the Media

Jeremy Iggers incorporates this history into his account of how journalism ethics confuses the purposes of journalism in “Good News, Bad News: Journalism Ethics and the Public Interest.”

Such is the basis for the media’s claims of “objectivity.” Starr’s history explains the forces leading to why this happened.

the blogosphere’s origins were not just Usenet, email lists and the like, they were also the underground press tracing back to IF Stone’s Weekly and George Seldes’ In Fact; the black press, both commercial and movement-based; political journals of the left and right; and so on

These underappreciated traditions provide largely untapped examples of how to do quality political journalism outside of the artificial construct in which false balance is rooted. They point the way forward for us, beyond our current state of asymmetrical dysfunction.

Kimberley Ann Perkins O'Connor, who captured part of the incident on her phone, told CNN she overheard the boy joking to his mother about going into the water. Then, suddenly, there he was, being dragged by Harambe.

Some suggested the boy's parents should be held criminally responsible for the incident. An online petition seeking "Justice for Harambe" earned more than 100,000 signatures in less than 48 hours.

"We had a very difficult situation and we made a difficult call at the end. I'm not here to point fingers about fault," he said.

"We live in the real world, we make real decisions. People and kids can climb over barriers. We work hard to make sure this zoo is safe. People can climb over barriers, that's what happened."

Western lowland gorillas are critically endangered in the wild, numbering fewer than 175,000, according to the zoo. An additional 765 gorillas dwell in zoos worldwide.

Harambe was put down, a decision that left many wondering if the zoo was too quick to shoot.

Although it was the first incident of its kind at Cincinnati Zoo's Gorilla World exhibit since it opened in 1978, similar cases have occurred with very different outcomes.

The footage shows Jambo, a male gorilla, approaching the boy as if to check on him, extending a hand to stroke his back. When Merritt comes to, wailing, Jambo, seemingly startled by the cries, sets off in a different direction. Zookeepers immediately move in to save the boy.

This time, a female gorilla named Binti Jua picked up the unconscious boy, while carrying her own infant on her back, and guarded him from other gorillas.

not always the gentle giants the world saw in these two cases -- the animal advocacy group People for the Ethical Treatment of Animals said the larger concept of zoos is the root of the problem.

Maynard said the zoo plans to reopen the exhibit to the public after a thorough assessment.
