From Spark To Flame

From LED displays to solar cells to handheld devices, nanocrystals have the potential to revolutionize electronic devices. The tiny crystals have diameters 1,000 times smaller than the width of a human hair, providing them with unique electronic properties that can improve devices and potentially shrink technologies down to the nanoscale. However, it can be challenging to efficiently arrange nanocrystals into the exact patterns necessary for such devices.

For simple, nanocrystal films, fabrication isn’t too difficult. Much like paint brushed onto a wall, the tiny crystals can be coated, sprayed or even printed to make uniform and useful films – but there is a limit to their complexity. Now, Dimitri Talapin’s lab at the University of Chicago has developed a method of herding nanocrystals into precise patterns, called direct optical lithography of functional inorganic nanomaterials (DOLFIN).

My boss pointed out the security concern, but she wasn’t taken seriously, so she took matters into her own hands. 

She bought a ticket and  pretended to be a guest. She entered through the main entrance with a huge drill clearly visible on her belt, went straight to the documents and opened the case with the drill. (While  wearing gloves,) she removed the documents, put them in a folder, reattached the glass, and walked out the main exit.  Literally no one even questioned her.

 She immediately went around to the back of the museum, entered using the staff entrance and went straight to her boss’s office.  She dropped the folder on his desk and said “I just stole these in 15 minutes“

“Ballet embraces the soft, ethereal and majestic side to women, and yet we often don’t see the media portray black women in this light. My project aims to reveal that women of color possess these qualities. We too are capable of portraying the princess, fairy and swan.”

 —Aesha Ash

Aesha Ash’s prestigious career has included world class roles. Yet she’s now on to a different mission, with three big goals. She wishes to see ballet become more diverse. She hopes to inspire youth from rough areas to pursue their dreams. And she wants to show the world that tough environments can’t hold back talented people, especially those with ambition.

Aesha performed professionally for 13 years. She attended the legendary School of American Ballet; joined the New York City Ballet at age 18; and has danced solo and principal roles for companies like the Béjart Ballet in Lausanne, Switzerland, and the Alonzo King Lines Ballet in San Francisco. Now she’s focused on The Swan Dreams Project, in which she uses imagery to tackle stereotypes placed on black women. Aesha commissions photographers to snap her as a ballerina in her hometown of rugged Rochester, New York, and in Richmond, California, and then donates proceeds from photo sales to organizations helping advance inner city youth. She also donates images to organizations for their fundraisers and to people seeking more positive imagery for their children or groups.

The dancer points out that black women have always existed in ballet, yet few become principals, the highest tier of dancers. When Misty Copeland became the first black female principal with the prestigious American Ballet Theatre last summer, Aesha found the milestone a moment to celebrate, yet sad and troubling that in 2016, we’re still celebrating a first. She hopes The Swan Dreams project will give more dancers — and youths in general — the chance to be celebrated for their own talents.

Rochester has one of America’s highest crime rates. But Aesha hits the streets to prove that her hometown is more than violence and gangs. That’s where her Swan Dreams Project comes in. “My community saw that out of our environment came a ballerina, not just negativity — a little black girl from inner city Rochester actually went on to become a professional ballet dancer in a top-tiered company,” Aesha said in a one-on-one interview for this report. “Youth followed me on the street saying, ‘This is what we need. This lifts us up.’”

The Researcher Who Helped Spark the Gay Rights Movement

45 years ago the American Psychiatric Association (APA) took homosexuality off the list of mental disorders. At that time, being gay was considered an illness that required psychiatric treatment.

It took decades of activism to change this — and also the work of groundbreaking researchers like UCLA psychologist Evelyn Hooker. 

Her research debunked the belief that homosexuality was a mental illness, ultimately leading to its removal from the APA’s handbook of disorders in 1973. 

I am an ER nurse and this is the best description of this event that I have ever heard. 

 FEMALE HEART ATTACKS 

 I was aware that female heart attacks are different, but this is description is so incredibly visceral that I feel like I have an entire new understanding of what it feels like to be living the symptoms on the inside. Women rarely have the same dramatic symptoms that men have… you know, the sudden stabbing pain in the chest, the cold sweat, grabbing the chest & dropping to the floor the we see in movies. Here is the story of one woman’s experience with a heart attack: 

 "I had a heart attack at about 10:30 PM with NO prior exertion, NO prior emotional trauma that one would suspect might have brought it on. I was sitting all snugly & warm on a cold evening, with my purring cat in my lap, reading an interesting story my friend had sent me, and actually thinking, ‘A-A-h, this is the life, all cozy and warm in my soft, cushy Lazy Boy with my feet propped up. A moment later, I felt that awful sensation of indigestion, when you’ve been in a hurry and grabbed a bite of sandwich and washed it down with a dash of water, and that hurried bite seems to feel like you’ve swallowed a golf ball going down the esophagus in slow motion and it is most uncomfortable. You realize you shouldn’t have gulped it down so fast and needed to chew it more thoroughly and this time drink a glass of water to hasten its progress down to the stomach. This was my initial sensation–the only trouble was that I hadn’t taken a bite of anything since about 5:00 p.m. 

After it seemed to subside, the next sensation was like little squeezing motions that seemed to be racing up my SPINE (hind-sight, it was probably my aorta spasms), gaining speed as they continued racing up and under my sternum (breast bone, where one presses rhythmically when administering CPR). This fascinating process continued on into my throat and branched out into both jaws. ‘AHA!! NOW I stopped puzzling about what was happening – we all have read and/or heard about pain in the jaws being one of the signals of an MI happening, haven’t we? I said aloud to myself and the cat, Dear God, I think I’m having a heart attack! I lowered the foot rest dumping the cat from my lap, started to take a step and fell on the floor instead. I thought to myself, If this is a heart attack, I shouldn’t be walking into the next room where the phone is or anywhere else… but, on the other hand, if I don’t, nobody will know that I need help, and if I wait any longer I may not be able to get up in a moment. 

I pulled myself up with the arms of the chair, walked slowly into the next room and dialed the Paramedics… I told her I thought I was having a heart attack due to the pressure building under the sternum and radiating into my jaws. I didn’t feel hysterical or afraid, just stating the facts. She said she was sending the Paramedics over immediately, asked if the front door was near to me, and if so, to un-bolt the door and then lie down on the floor where they could see me when they came in. I unlocked the door and then laid down on the floor as instructed and lost consciousness, as I don’t remember the medics coming in, their examination, lifting me onto a gurney or getting me into their ambulance, or hearing the call they made to St. Jude ER on the way, but I did briefly awaken when we arrived and saw that the radiologist was already there in his surgical blues and cap, helping the medics pull my stretcher out of the ambulance. He was bending over me asking questions (probably something like ‘Have you taken any medications?’) but I couldn’t make my mind interpret what he was saying, or form an answer, and nodded off again, not waking up until the Cardiologist and partner had already threaded the teeny angiogram balloon up my femoral artery into the aorta and into my heart where they installed 2 side by side stints to hold open my right coronary artery. 

I know it sounds like all my thinking and actions at home must have taken at least 20-30 minutes before calling the paramedics, but actually it took perhaps 4-5 minutes before the call, and both the fire station and St Jude are only minutes away from my home, and my Cardiologist was already to go to the OR in his scrubs and get going on restarting my heart (which had stopped somewhere between my arrival and the procedure) and installing the stents. Why have I written all of this to you with so much detail? Because I want all of you who are so important in my life to know what I learned first hand. 

1. Be aware that something very different is happening in your body, not the usual men’s symptoms but inexplicable things happening (until my sternum and jaws got into the act). It is said that many more women than men die of their first (and last) MI because they didn’t know they were having one and commonly mistake it as indigestion, take some Maalox or other anti-heartburn preparation and go to bed, hoping they’ll feel better in the morning when they wake up… which doesn’t happen. My female friends, your symptoms might not be exactly like mine, so I advise you to call the Paramedics if ANYTHING is unpleasantly happening that you’ve not felt before. It is better to have a ‘false alarm’ visitation than to risk your life guessing what it might be! 2. Note that I said ‘Call the Paramedics.’ And if you can take an aspirin. Ladies, TIME IS OF THE ESSENCE! Do NOT try to drive yourself to the ER - you are a hazard to others on the road. Do NOT have your panicked husband who will be speeding and looking anxiously at what’s happening with you instead of the road. Do NOT call your doctor – he doesn’t know where you live and if it’s at night you won’t reach him anyway, and if it’s daytime, his assistants (or answering service) will tell you to call the Paramedics. He doesn’t carry the equipment in his car that you need to be saved! The Paramedics do, principally OXYGEN that you need ASAP. Your Dr. will be notified later. 3. Don’t assume it couldn’t be a heart attack because you have a normal cholesterol count. Research has discovered that a cholesterol elevated reading is rarely the cause of an MI (unless it’s unbelievably high and/or accompanied by high blood pressure). MIs are usually caused by long-term stress and inflammation in the body, which dumps all sorts of deadly hormones into your system to sludge things up in there. Pain in the jaw can wake you from a sound sleep. Let’s be careful and be aware. The more we know the better chance we could survive to tell the tale.“

Now that’s how you ally. That’s putting it on the line and showing solidarity. That’s how you use your white privilege for good.

Tolkien wrote The Hobbit like waaaay before he even dreamed up the idea for Lord of the Rings, so when he DID dream up LotR, he had a whole bunch of stuff that didn’t make sense. Like plotholes galore

Like for example in the first version Gollum was a pretty nice dude who lost the riddle contest graciously and gave Bilbo the ring as a legit present and was very helpful and it was super nice and polite and absolutely nobody tried to eat anyone because this is a story for kids and that’s very rude

But that doesn’t work with LotR, so Tolkien went back and re-released an updated version of The Hobbit with all the lore changes and stuff to fix everything that didn’t work

This is the version we know and love today

BUT rather than pretend the early version never existed, Tolkien went and worked the retcon into the lore

If you pay attention in Fellowship, there’s a bit where Gandalf is telling Frodo about the ring and he mentions how Bilbo wasn’t entirely honest about the manner in which it was found

To us modern readers, this doesn’t make a ton of sense, so mostly we just breeze by it–but actually that line is referencing the first version of The Hobbit

The pre-retcon version of the Hobbit is canonically Bilbo’s original book. The original version with Nice Gollum is canonically a lie Bilbo told to legitimize his claim to the ring and absolve him of the guilt he feels for his rather shady behavior

Then the post-retcon version is an in-universe edited edition someone went and released later to straighten out Bilbo’s lies

So it’s 100% plausible that the in-universe editor who fixed up Bilbo’s Red Book and translated it from whatever language Hobbits speak was a human who knew about Christmas Trees and tossed the detail in to make human readers feel more at home, because that’s the kind of thing that sometimes happens when you have a translator editor person dressing up a story for an audience that doesn’t know the exact cultural context in which the original story was written

Tolkien was a medieval scholar and medieval stories are rife with that sort of thing, so like… yeah
