Opinion | Democrats Appealing to the Heart? Yes, Please - The New York Times

It is a longstanding stereotype that, when it comes to political combat, Democrats aim for the electorate’s head while Republicans aim for its gut. The emotional route tends to be discussed in largely negative terms, with Republicans accused of fearmongering on issues ranging from gay marriage to crime to immigration. There is maybe no more glaring case study of this than the 2016 matchup between Hillary Clinton, with her reputation as an overachieving wonk incapable of connecting with voters, and Donald Trump, with his know-nothing, visceral demagogy. Candidate Trump had few policy ideas and may have known less about how government works than any nominee in the history of the Republic. But he was, and is, a master at connecting — albeit on a dark, primordial level.

But this trend goes beyond any specific contest. Reams have been written about how Democrats more often operate with an eye toward wooing voters with more rational, data-driven appeals. As Drew Westen, a professor of psychology at Emory University and the author of the 2005 book “The Political Brain,” has noted, “Democrats typically bombard voters with laundry lists of issues, facts, figures and policy positions, while Republicans offer them emotionally compelling appeals, whether to their values, principles or prejudices.” In that sense, there’s truth to the Republican attack line that Democrats are a bunch of know-it-all elitists who think they are so much smarter than “regular” Americans: Democratic politicians all too often convey the impression that, if only they could make the electorate understand the superiority of their policies, victory would follow.

Except that most voters don’t vote on policy specifics. Despite fancying themselves rational creatures, people are often more influenced by tribal identification or the personal appeal of a candidate.

Of course, this political stereotype, like all stereotypes, is an oversimplification — and one with notable exceptions. (Two words: Bill Clinton.) But it does suggest that Democrats could work a bit harder on their emotional savvy.

The history of the Tulsa race massacre that destroyed America’s wealthiest black neighborhood

1921, Tulsa had the wealthiest black neighborhood in the country. On Sundays, women wore satin dresses and diamonds, while men wore silk shirts and gold chains. In Greenwood, writes historian James S. Hirsch, “Teachers lived in brick homes furnished with Louis XIV dining room sets, fine china, and Steinway pianos.”
They called it Black Wall Street.
“They had done everything that they were supposed to do in terms of the American dream,” says Carol Anderson, Professor of African American Studies at Emory University. “You work hard, you save your money, you go to school, you buy property. And this is what they had done under horrific conditions.”
Greenwood was strictly segregated from the rest of the city, but still it flourished. It was home to black lawyers, business owners, and doctors — including Dr. A.C. Jackson, who was considered the most skilled black surgeon in America and had a net worth of $100,000.
Dr. Jackson was killed on the night of May 31st, 1921, along with hundreds of black Tulsans. Thirty-five blocks of Greenwood were razed that night. 1,256 homes and 191 businesses were destroyed. 10,000 black people were left homeless.
By morning, Black Wall Street had been reduced to rubble.

Stanford researchers ‘stunned’ by stem cell experiment that helped stroke patient walk

While the research involved only 18 patients and was designed primarily to look at the safety of such a procedure and not its effectiveness, it is creating significant buzz in the neuroscience community because the results appear to contradict a core belief about brain damage — that it is permanent and irreversible.

The results, published in the journal Stroke, could have implications for our understanding of an array of disorders including traumatic brain injury, spinal cord injury and Alzheimer’s if confirmed in larger-scale testing.

The work involved patients who had passed the critical six-month mark when recoveries generally plateau and there are rarely further improvements. [...]

The one-time therapy involved surgeons drilling a hole into the study participants’ skulls and injecting stem cells in several locations around the area damaged by the stroke. These stem cells were harvested from the bone marrow of adult donors. While the procedure sounds dramatic, it is considered relatively simple as far as brain surgery goes. The patients were conscious the whole time and went home the same day.

[...]

“Their recovery was not just a minimal recovery like someone who couldn’t move a thumb now being able to wiggle it. It was much more meaningful. One 71-year-old wheelchair-bound patient was walking again,” said [Gary] Steinberg [the study’s lead author and chair of neurosurgery at Stanford] who personally performed most of the surgeries.

[...]

Steinberg said that the study does not support the idea that the injected stem cells become neurons, as has been previously thought. Instead, it suggests that they seem to trigger some kind of biochemical process that enhances the brain’s ability to repair itself.

“A theory is that they turn the adult brain into the neonatal brain that recovers well,” he explained.

[...]

Nicholas Boulis, a neurosurgeon and researcher at Emory University, said the study appears to support the idea that there may be latent pathways in the brain that can be reactivated — a theory that has been “working its way to the surface” over the past few years.

Alors que le Conseil de sécurité de l’ONU se réunit ce 18 septembre pour étudier un projet de résolution afin d’éradiquer l’épidémie, sur le terrain, c’est le sauve-qui-peut. Le sang de ceux qui ont survécu à la maladie est l’objet d’un commerce.
