Octopus genome holds clues to uncanny intelligence

Nature reports: Researchers want to understand how the cephalopods, a class of free-floating molluscs, produced a creature that is clever enough to navigate highly complex mazes and open jars filled with tasty crabs.

Surprisingly, the octopus genome turned out to be almost as large as a human’s and to contain a greater number of protein-coding genes — some 33,000, compared with fewer than 25,000 in Homo sapiens.

This excess results mostly from the expansion of a few specific gene families, [neurobiologist Clifton] Ragsdale says. One of the most remarkable gene groups is the protocadherins, which regulate the development of neurons and the short-range interactions between them. The octopus has 168 of these genes — more than twice as many as mammals. This resonates with the creature’s unusually large brain and the organ’s even-stranger anatomy. Of the octopus’s half a billion neurons — six times the number in a mouse — two-thirds spill out from its head through its arms, without the involvement of long-range fibres such as those in vertebrate spinal cords. The independent computing power of the arms, which can execute cognitive tasks even when dismembered, have made octopuses an object of study for neurobiologists such as Hochner and for roboticists who are collaborating on the development of soft, flexible robots.

A gene family that is involved in development, the zinc-finger transcription factors, is also highly expanded in octopuses. At around 1,800 genes, it is the second-largest gene family to be discovered in an animal, after the elephant’s 2,000 olfactory-receptor genes. [Continue reading…]

The coddling of the American mind

Greg Lukianoff and Jonathan Haidt write: Something strange is happening at America’s colleges and universities. A movement is arising, undirected and driven largely by students, to scrub campuses clean of words, ideas, and subjects that might cause discomfort or give offense. Last December, Jeannie Suk wrote in an online article for The New Yorker about law students asking her fellow professors at Harvard not to teach rape law — or, in one case, even use the word violate (as in “that violates the law”) lest it cause students distress. In February, Laura Kipnis, a professor at Northwestern University, wrote an essay in The Chronicle of Higher Education describing a new campus politics of sexual paranoia — and was then subjected to a long investigation after students who were offended by the article and by a tweet she’d sent filed Title IX complaints against her. In June, a professor protecting himself with a pseudonym wrote an essay for Vox describing how gingerly he now has to teach. “I’m a Liberal Professor, and My Liberal Students Terrify Me,” the headline said. A number of popular comedians, including Chris Rock, have stopped performing on college campuses (see Caitlin Flanagan’s article in this month’s issue). Jerry Seinfeld and Bill Maher have publicly condemned the oversensitivity of college students, saying too many of them can’t take a joke.

Two terms have risen quickly from obscurity into common campus parlance. Microaggressions are small actions or word choices that seem on their face to have no malicious intent but that are thought of as a kind of violence nonetheless. For example, by some campus guidelines, it is a microaggression to ask an Asian American or Latino American “Where were you born?,” because this implies that he or she is not a real American. Trigger warnings are alerts that professors are expected to issue if something in a course might cause a strong emotional response. For example, some students have called for warnings that Chinua Achebe’s Things Fall Apart describes racial violence and that F. Scott Fitzgerald’s The Great Gatsby portrays misogyny and physical abuse, so that students who have been previously victimized by racism or domestic violence can choose to avoid these works, which they believe might “trigger” a recurrence of past trauma.

Some recent campus actions border on the surreal. In April, at Brandeis University, the Asian American student association sought to raise awareness of microaggressions against Asians through an installation on the steps of an academic hall. The installation gave examples of microaggressions such as “Aren’t you supposed to be good at math?” and “I’m colorblind! I don’t see race.” But a backlash arose among other Asian American students, who felt that the display itself was a microaggression. The association removed the installation, and its president wrote an e-mail to the entire student body apologizing to anyone who was “triggered or hurt by the content of the microaggressions.” [Continue reading…]

Your gut bacteria don’t like junk food – even if you do

By Tim Spector, King’s College London

When Morgan Spurlock famously spent a month eating large portions of McDonalds for the purposes of his documentary Supersize Me, he gained weight, damaged his liver and claimed to have suffered addictive withdrawal symptoms. This was popularly attributed to the toxic mix of carbs and fat plus the added chemicals and preservatives in junk foods. But could there be another explanation?

We may have forgotten others who really don’t enjoy fast food. These are the poor creatures that live in the dark in our guts. These are the hundred trillion microbes that outnumber our total human cells ten to one and digest our food, provide many vitamins and nutrients and keep us healthy. Until recently we have viewed them as harmful – but those (like salmonella) are a tiny minority and most are essential for us.

Studies in lab mice have shown that when fed an intensive high fat diet their microbes change dramatically and for the worse. This can be partly prevented by using probiotics; but there are obvious differences between us and lab mice, as well as our natural microbes.

Defeating ISIS in Syria is essential to prevent catastrophe

Frederic C Hof writes: Islamic State (Isis) is the catastrophic consequence of political illegitimacy in Iraq and Syria. In Iraq, the prime minister, Nouri al-Maliki, created a governance vacuum. With the unflagging support of Iran, he disenfranchised and alienated Sunni Arabs through narrow, partisan and utterly sectarian policies. In Syria the vacuum’s creator is Bashar al-Assad – with the enthusiastic backing of Iran, he pursues a political survival strategy of collective punishment, featuring mass homicide focused on civilians. Legitimate governance in both places may be a long way off. But keeping Isis from sinking roots in Syria is an urgent priority, which, if unmet, will enable this criminal band to sustain its combat operations in Iraq from a secure rear area where it will also menace Turkey and Jordan.

Political legitimacy – a condition in which the citizenry agrees on the rules of the political game – is a tall order for the two countries in question. Can Iraq survive as a state, even as a confederation? Is there a future for Syria within borders drawn during the colonial era? Surely a stable, peaceful and confederated Iraq is not right around the corner. And for Syria, reconstruction, reform, and reconciliation may be generational undertakings.

No doubt the process of overcoming the conditions that made large swaths of Iraq and Syria safe for Isis will be a long one. The hardships associated with this process will be borne in large measure by Syrians and Iraqis. Yet to admit that the struggle for political legitimacy will be extended is not to say that the battle against Isis must be a multi-year engagement. Indeed, in Syria it must not be, as this deadly combination of al-Qaida and Saddam Hussein loyalists seeks to establish itself in a country where it has no natural constituency. [Continue reading…]

New diplomacy seen on U.S.-Russian efforts to end Syrian civil war

The New York Times reports: With President Bashar al-Assad of Syria facing battlefield setbacks, diplomats from Russia, the United States and several Middle Eastern powers are engaged in a burst of diplomatic activity, trying to head off a deeper collapse of the country that could further strengthen the militant group Islamic State.

Russia, Mr. Assad’s most powerful backer, has built new ties with Saudi Arabia, a fervent opponent, and even brokered a meeting between high-ranking Saudi and Syrian intelligence officials. On Tuesday, the Saudi foreign minister, Adel al-Jubeir, met with the Russian foreign minister, Sergey V. Lavrov, in Moscow, wrangling over the fate of Mr. Assad.

Unusual meetings have come in quick succession. Last week, the top Russian, American and Saudi envoys held their first three-way meeting on Syria; Russian officials briefed Syria’s foreign minister, Walid al-Moallem. He then met officials in Oman, whose ties to both Saudi Arabia and Iran raised the prospect of talks between those archrivals. Russia stopped blocking an international inquiry into who has used chemical weapons in Syria, a longstanding American priority. [Continue reading…]

Dozens of retired generals, admirals back Iran nuclear deal

The Washington Post reports: Three dozen retired generals and admirals released an open letter Tuesday supporting the Iran nuclear deal and urging Congress to do the same.

Calling the agreement “the most effective means currently available to prevent Iran from obtaining nuclear weapons,” the letter said that gaining international support for military action against Iran, should that ever become necessary, “would only be possible if we have first given the diplomatic path a chance.”

The release came as Secretary of State John F. Kerry said U.S. allies were “going to look at us and laugh” if the United States were to abandon the deal and then ask them to back a more aggressive posture against Iran. [Continue reading…]

Head of group opposing Iran accord quits post, saying he backs deal

The New York Times reports: When the bipartisan advocacy group United Against Nuclear Iran decided last week to mobilize opposition against the nuclear deal with Tehran, Gary Samore knew he could no longer serve as its president.

The reason: After long study, Mr. Samore, a former nuclear adviser to President Obama, had concluded that the accord was in the United States’ interest.

“I think President Obama’s strategy succeeded,” said Mr. Samore, who left his post on Monday. “He has created economic leverage and traded it away for Iranian nuclear concessions.”

As soon as Mr. Samore left, the group announced a new standard-bearer with a decidedly different message: Joseph I. Lieberman, the former senator from Connecticut and the new chairman of the group. [Continue reading…]

Ordinary Iranians unafraid to criticize their own government

Larry Cohler-Esses (from The Forward), “the first journalist from a Jewish, pro-Israel (if not always pro-Israel government) publication to be granted a journalist’s visa since the 1979 Revolution,” writes: Ordinary Iranians with whom I spoke have no interest at all in attacking Israel; their concern is with their own sense of isolation and economic struggle. Official government statistics estimate the unemployment in Iran at around 10%. But unofficial sources estimate it as twice that — and this in a context in which only 36% of the population participates in the workforce. An estimated 150,000 Iranians with college educations leave the country yearly.

But among ordinary Iranians the sense that something is now opening up in the country is pervasive. It began with the election of the reformist presidential candidate Rouhani in 2012, long before the recently negotiated nuclear agreement introduced the prospect of crippling sanctions being lifted. And the impact of this mood on people’s willingness to speak out is clear.

In Iran today, freedom of the press remains a dream. But freedom of tongue has been set loose. I was repeatedly struck by the willingness of Iranians to offer sharp, even withering criticisms of their government on the record, sometimes even happy to be filmed doing so.

“The people of Iran want in some way to show the world that what’s going on in the last years is not the will of the Iranian people but of the Iranian government,” Nader Qaderi told me as I filmed him with my phone outside his butcher shop in North Tehran’s Tajrish Market. A small crowd looked on as we talked. “We have no hostility against Israel,” he stressed.

Asked about prospects for the international nuclear agreement, which is coming under angry fire in Iran no less than in the United States, Qaderi told me: “I think it will be implemented. But there will be no improvement for the Iranian people. Our main concern now is freedom! I think what we need most of all now is political intelligence. People have no clear idea of what they want. This is the real struggle.” [Continue reading…]

Iran deal furor reveals a split among Jewish Americans

Lisa Goldman reports: The frenzied lobbying in Washington over the international deal to limit Iran’s nuclear program has drawn attention to two unprecedented ruptures — both of which potentially have significant long-term consequences for Israel’s place in U.S. domestic politics.

For decades, unconditional support for Israel had been a point of unshakable bipartisan consensus inside the Beltway, even as bipartisanship on most other issues became a distant memory. A majority of Jewish voters continue to choose the Democrats; deep-pocketed Jewish donors remain vital to the electoral prospects of candidates from both parties, but partisan distinctions meant little when it came to Israel. And the pro-Israel lobbying establishment, first and foremost the America Israel Public Affairs Committee (AIPAC) has always worked hard to span the aisle on Capitol Hill, while political leaders from both parties routinely pay tribute to the lobbying group at its annual convention.

The Iran nuclear deal has thrown that consensus into crisis, leaving Jewish Americans divided between a Democratic-voting majority that polls show support the Iran deal (in numbers proportionally larger than the wider U.S. population) and a conservative minority that includes some very powerful donors, and supports the GOP-led opposition to the deal. And AIPAC’s leading role in campaigning against the deal has prompted President Barack Obama to publicly challenge the group in a manner unprecedented for a U.S. leader over the past two decades.

Images of Iranian parking lot reveal evidence of cars, parked

Bloomberg reports: An Iranian parking lot labeled as a site of “intense concern” by an influential Washington research group hasn’t shown any signs of change for at least five years, according to satellite imagery and analysts.

The Institute for Science and International Security, or ISIS, said in an Aug. 7 research note that Iran’s decision to park 20 vehicles at the Parchin military complex facility was provocative. However, according to 36 satellite images spanning five years, there has always been an average of about 20 automobiles parked at the site since concern over the Parchin complex grew in 2011.

“The ‘parking lot of death’ has been imaged dozens of times and there are clear patterns of passenger cars parked there,” said Robert Kelley, an intelligence analyst and former U.S. nuclear-weapons scientist. “There have been no indicators of a change in Iranian activities of any significance — no earth moving or sanitization whatsoever.”

With debate flaring in Washington over the July 14 agreement between Iran and world powers, some analysts and politicians say activities at Parchin underline the risks of entering into a deal with the Islamic Republic. In a statement on Saturday, Iran said analysts had confused normal roadwork with malicious intentions at the 50 square-kilometer (31 square-mile) complex.

“Parchin is an active site and movement is inevitable,” Paul Ingram, executive director of the British American Security Information Council, said in an e-mailed reply to questions. “Attempting an impossible cleanup in full view of satellites and just before Congressional votes would be stretching conspiracy theories beyond breaking point.” [Continue reading…]

Inside the secret U.S.-Iran diplomacy that sealed nuke deal

Laura Rozen reports: When Hassan Rouhani was elected Iran’s president in June 2013 on a campaign platform of engaging with the West to reach a nuclear deal and improve Iran’s economy, he apparently didn’t know that Iran and the United States had already opened a secret diplomatic channel and held bilateral talks in Oman on the nuclear issue in March 2013.

“The first time I informed Rouhani of the secret negotiations with the United States was after his election to office,” former Iranian Foreign Minister Ali Akbar Salehi said in an interview Aug. 4 with Iran Daily, adding that the incoming president and former Iranian nuclear negotiator was shocked when Salehi briefed him on the consultations ahead of his inauguration: “Rouhani was in disbelief.”

That is among the revelations that have emerged from interviews with senior Iranian and US officials in the wake of reaching of a final Iran nuclear accord by Iran and six world powers on July 14. The final deal — formally called the Joint Comprehensive Plan of Action — is currently under a 60-day review by the US Congress. Israeli Prime Minister Benjamin Netanyahu and some pro-Israel lobby groups are pressing members of Congress to kill the deal by voting next month on a resolution of disapproval that seeks to block President Barack Obama from providing the US sanctions relief promised in the accord in exchange for significant steps Iran agreed to take to limit its nuclear program. Obama has vowed to veto any such resolution, and Democrats currently believe they have enough support to sustain his veto, if required. [Continue reading…]

Iraqi political reforms risk further marginalization of Sunnis

The New York Times reports: Iraq’s Parliament unanimously passed measures on Tuesday that are meant to transform the country’s corrupt political system. Yet by eliminating several high-level positions and doing away with sectarian quotas in political appointments, the measures risk further alienating the country’s Sunni minority while the government is struggling to defeat the Sunni militants of the Islamic State.

The measures, put forward on Sunday by Prime Minister Haider al-Abadi, are wide-ranging. They promise to save money and fight corruption by cutting expensive perks for officials. Most notably, they eliminate three deputy prime minister posts and three vice presidencies, including the one held by former Prime Minister Nuri Kamal al-Maliki, who was a rival of Mr. Abadi.

The passage of the measures was never really in doubt. They were backed by the country’s leading Shiite cleric, Grand Ayatollah Ali al-Sistani, who holds great sway over the country’s Shiite majority. And a sense of public grievance at the current system has been swelling in the streets, culminating in widespread protests. [Continue reading…]

Discover a society with no absolutes, populated by the ultimate empiricists — people happy without God

Daniel Everett summarizes the lesson for linguistics from his research of the Pirahã people and their language:

The lesson is that language is not something mysterious that is outside the bounds of natural selection, or just popped into being through some mutated gene. But that language is a human invention to solve a human problem. Other creatures can’t use it for the same reason they can’t use a shovel: it was invented by humans, for humans and its success is judged by humans.

Jewish terrorism targeting Palestinians is nothing new

The Daily Beast reports: Raphael Morris, a 20-year-old religious settler from the outpost of Ahiya, has for years engaged in a “holy war,” he tells The Daily Beast. He’s battling to rid Israel of its non-Jewish elements and expand the settlement enterprise in Judea and Samaria—the biblical term for the land on the West Bank of the Jordan River that once belonged to the ancient kingdom of Israel.

Six years ago, Morris arrived at a nearby outpost with 10 other teenagers and learned to work the vineyard, build houses, and “in a number of instances” created a line of defense against the surrounding Palestinian villages. “The Arabs knew not to mess with us,” he says.

This area of the West Bank is home to dozens of outposts initiated in defiance of the Israeli government by mainly Orthodox teenagers and young families known as “hilltop youth.” But these communities are also breeding a zealous culture of Jewish militancy that has led to intensifying attacks on Palestinian towns.

Ahiya is only a short distance from the village of Duma, where on July 31 Jewish extremists firebombed two Arab homes in the dead of night.

One of the houses was empty, but in the other four members of the same family were sleeping in one bedroom. Eighteen-month-old Ali Saad Dawabshah was immediately burned to death, and his father, Saad Dawabshah, succumbed two weeks later to the third-degree burns that covered more than 80 percent of his body. The mother, Reham, and her four-year-old son, Ahmad, remain in critical condition in an Israeli hospital and few family members expect them to survive.

On the walls of the house the arsonists left graffiti reading “Revenge!” and “Long Live the Messiah” next to a Star of David.

The brutal attacks have shocked Israel, prompting nation-wide “soul searching” as Prime Minister Benjamin Netanyahu and other Israeli politicians condemn the act as “Jewish terror.” But such incidents are neither so new nor so isolated as these denunciations would make them seem.

Republican hopefuls reap $62m in support from donors with fossil fuel ties

The Guardian reports: Republican presidential candidates have banked millions of dollars in donations from a small number of mega-rich individuals and corporations with close ties to the fossil fuel industries that stand to lose the most from the fight against climate change.

Eight out of the 17 GOP figures currently jostling for their party’s presidential nomination have between them attracted a bonanza of at least $62m so far this year from sources either directly involved in polluting industries or with close financial ties to them. Three Republican contenders stand out as recipients of this fossil fuel largesse: the Republican climate change denier-in-chief, Ted Cruz; the party establishment favorite Jeb Bush; and the former governor of Texas, Rick Perry.

The funds have come from just 17 billionaires or businesses that have pumped enormous sums – in one case $15m for a single candidate – into the support groups or Super Pacs that work alongside the official campaigns yet are free to attract unlimited contributions. The $62m forms a substantial chunk of almost $400m that has been given to presidential contenders from both main parties in 2015, raising questions about the leverage that fossil fuel interests might seek to exert over the next occupant of the White House at a critical time for the battle against climate change.

Not just the editorial page — WSJ reporting on climate change also skewed

Media Matters reports: When it comes to covering climate change, it’s not just The Wall Street Journal’s editorial section that is problematic in the Rupert Murdoch era — a new study shows the paper’s newsroom has misinformed readers on the issue, too.

A new joint study from researchers at Rutgers University, the University of Michigan, and the University of Oslo appearing in the journal Public Understanding of Science (PUS) found major differences between the climate change reporting of The Wall Street Journal and other major U.S. newspapers. The July 30 study, titled “Polarizing news? Representations of threat and efficacy in leading US newspapers’ coverage of climate change,” examined non-opinion-based climate change articles in The Journal, The New York Times, USA Today, and The Washington Post from 2006 to 2011.

The study found some disturbing trends in The Wall Street Journal’s news reporting on climate change, including that the Journal was less likely than the other newspapers to discuss the threats or impacts of climate change and more likely to frame climate action as ineffective or even harmful. The authors of the study concluded that, given the Journal’s conservative readership, the negative nature of its climate reporting “could exacerbate ideological polarization on climate change.” [Continue reading…]

For years, American trophy hunters have been flocking to Iran

BBC News reports: The furore over the killing by a US dentist of Cecil the lion in Zimbabwe has thrown a spotlight on trophy hunting – but while Africa is commonly associated with the sport, American enthusiasts are finding another popular hunting destination – the Islamic Republic of Iran.

Every year, Iran’s Environment Protection Agency issues about 500 licences to foreign visitors to hunt rare and protected breeds.

Many of these hunters come from the US, despite the absence of diplomatic relations and a state of tension between the two countries for the past 35 years.

They have been heading there since the US Treasury Department’s Office of Foreign Assets Control (Ofac) made it legal for US agencies to book hunting tours to Iran more than a decade ago. [Continue reading…]
