"We’re eye doctors."
"What’s something about the eye that most people don’t realize?"
"The eye doesn’t see. The brain sees. The eye just transmits. So what we see isn’t only determined by what comes through the eyes. What we see is affected by our memories, our feelings, and by what we’ve seen before."
"I’d say 20 percent of the people sleeping at my shelter want to improve their condition, and become self-supporting. Another 30 percent are mentally unstable. And it seems the other 50 percent have just grown comfortable with being taken care of, and don’t have any plans beyond smoking or drinking. It’s this last 50 percent that make it so difficult for the 20 percent of us who really want to change our lives. But they actually motivate me. Because I never want to be like them."
I’d say he is 100% accurate.
Jesus was a radical, non-violent revolutionary who hung around with lepers, hookers and crooks; wasn’t American and never spoke English; was anti-wealth, anti-death penalty, anti-public prayer (M 6:5), but was never anti-gay; never mentioned abortion or birth control; never called the poor ‘lazy’; never justified torture; never fought for tax cuts for the wealthiest Nazarenes; never asked a leper for a co-pay; and was a long-haired, brown-skinned, homeless, community-organizing, anti-slut-shaming, Middle Eastern Jew.

Oral Fungal Fight
Oral candidiasis, usually called thrush, is a fungal infection of the mouth that often affects people with HIV. By cataloguing oral microbiomes in healthy people and HIV patients, scientists might have found a new way to tackle the problem. There was little difference in oral bacteria between the two groups, but clear disparities when it came to fungi. A fungal family called Candida was more abundant in HIV-infected individuals than healthy people, while another family, Pichia, was less plentiful in HIV patients than others. This suggested the two types of fungi might be engaged in battle. Sure enough, as the image shows, the tongues of mice treated with Pichia (right) hosted hardly any Candida (magenta flecks) compared with those of untreated mice (left). If scientists can work out exactly how Pichia inhibits its fungal foe, they could potentially develop new ways to manage oral thrush and other, more dangerous fungal infections.

What is it? Where is it? And… how did it get there?
Any person wondering “is that a cucumber?” does not appreciate the great utility of CT density. A cucumber is mainly water and so would appear grey on CT but this vegetable is black and so contains a lot of air. Can you think of a vegetable that is a similar shape to a cucumber but is a lot less dense? If you can then you have just learnt one answer to this quiz question. The next thing to learn is that this vegetable is best taken orally!
