If you've ever had a flight connect at DFW airport, you may have seen this mural, depicting my beloved Caddo Lake, created by Dallas artist Arthello Beck Jr.
Beck was the first African-American to own & operate an art gallery in Texas & launched careers for many Texas artists.
He grew up in Oak Cliff in Dallas, received no formal training beyond art class at Lincoln High School. He worked as a postal worker, a driver for Dallas MHRC, but always he was at the Dallas Public Library, looking at art.
He had a speech impediment, so art was his language.
His art depicts life growing up in Jim Crow Texas (he was born in 1941), through segregation, and he believed in grassroots and Black liberation.
He opened his gallery in 1973, mostly with his own paintings, but featuring other Black artists from the area.
He owned the gallery for more than 30 years, and created an entire culture of Black art in Oak Cliff.
I'm not an art critic, but I think his paintings and sketches have a simplicity of emotion, and capture moments of time quite well.
He and I lived in the same spaces, saw the same images, but in his art, I can see a perspective that I probably couldn't access otherwise.
That's the power of art, I suppose.
A memorial was put up near where his art studio was located, depicting some of his favorite works. The Dallas Museum of Art displayed some of his paintings as part of the Grant Hill collection 2004-2005.
Some lovely quotes from friends:
"He used his art to bring about a higher level of consciousness in the community, for he understood the purpose of art was to tell the truth."
Look, nobody likes hearing it, but #DaveGrohl was a full-blown AIDS denialist & has never apologized for or acknowledged his support for a movement that caused hundreds of thousands of deaths worldwide. medium.com/the-monthly/th…
Yes he was young and idealistic, but it's the absolute silence on the subject in the years since.
He watched the last member of the Alive and Well With AIDS denialist organization die, and a few months later, quietly removed all references to them from the Foo Fighters webpage.
They did concerts, benefits for anti-vax and AIDS denialist groups. They gave contributions. They appeared in propaganda films, telling people not to take life-saving medicine prescribed by their doctor.
You may know:
~8% of human genome is made up of HERVs (human endogenous retroviruses).
They've thrown their lot in with us: we preserve them in our genome & they protect us from other viruses.
Viruses on 'Team Human'.
Pet Viruses.
HERV sequences & products shape & are shaped by our immune systems.
Our cells sometimes recognize them as internal viral invaders & express gene products related to viral immunity, the interferon pathways. This can lead to autoimmunity OR control of excessive immune activity.
A particular one, HERV-K(HML10) landed in the Major Histocompatibility Region (MHR) and is responsible for some human variation in tissue donation compatibility.
Let's talk about why mammalian red blood cells (erythrocytes) don't have nuclei.
~85% of all your cells are erythrocytes, 20-30 trillion of them in an adult.
You produce >2 million every second & they represent half of all your blood volume. So why don't they have any DNA?
We can talk about the ways that erythrocytes are optimized for transporting hemoglobin(Hb)-bound oxygen throughout our tissues:
No nuclei means no metabolism or cell machinery, so an RBC becomes just a small, flexible bag of Hb, which means they can travel down even the tiniest of blood vessels, and deliver oxygen payloads into the interstitial spaces.
Roman god 'Liber', god of the vine & male fertility, was later merged with Bacchus. He was son of Ceres, brother/consort to Libera.
Liber pater ('Free Father') was patron god of plebians, patron of male virility & boys becoming men.
A Liberalia was a festival of the cult of Liber Pater & it was celebrated when boys took manly toga virilis w phallic symbols & "a giant penis on a trolley".
Liberalia celebrated drinking, free speech & overthrow of political structures, making cult dangerous to establishment.
The point is that Liber Pater was in favor of the poor & powerless getting drunk & overthrowing leaders. He was a god of anarchy & plebian values.
In late Republic, Cicero was careful to say that "Liber was not identical to Bacchus": rebellion & equality, not chaos.
