Basic research challenges China's monopoly on rare earth elements

Materials that are essential for the transition to a sustainable society are currently being extracted using methods that are far from sustainable or environment-friendly. Magnets based on REE are manufactured in China, which has very different legislation to Sweden, for example. "It's a geopolitical problem," says Martin Sahlberg, Professor of Materials Chemistry at Uppsala University. "In the last year with the trade war and the U.S. tariffs, we've seen that China halted exports of rare earth elements. We can also mention Trump's move on Greenland and the Ukraine–United States Mineral Resources Agreement as other examples of geopolitical conflicts." You need toxic chemicals to purify and isolate rare earth elements from rare earth minerals, and radioactive elements are often found in the same places. "It's rather a dirty business today," says Sahlberg.

Covid-19 Alters Gray Matter Volume in the Brain

Covid-19 patients who receive oxygen therapy or experience fever show reduced gray matter volume in the frontal-temporal network of the brain, according to a new study led by researchers at Georgia State University and the Georgia Institute of Technology.

The study found lower gray matter volume in this brain region was associated with a higher level of disability among Covid-19 patients, even six months after hospital discharge.

Gray matter is vital for processing information in the brain and gray matter abnormality may affect how well neurons function and communicate. The study, published in Neurobiology of Stress, indicates gray matter in the frontal network could represent a core region for brain involvement in Covid-19, even beyond damage related to clinical manifestations of the disease, such as stroke.

The researchers, who are affiliated with the Center for Translational Research in Neuroimaging and Data Science (TReNDS), analyzed computed tomography scans in 120 neurological patients, including 58 with acute Covid-19 and 62 without Covid-19, matched for age, gender and disease. The work was done jointly with Enrico Premi and his colleagues at the University of Brescia in Italy, who provided the data for the study. They used source-based morphometry analysis, which boosts the statistical power for studies with a moderate sample size.

“Science has shown that the brain’s structure affects its function, and abnormal brain imaging has emerged as a major feature of Covid-19,” said Kuaikuai Duan, the study’s first author, a graduate research assistant at TReNDS and Ph.D. student in Georgia Tech’s School of Electrical and Computer Engineering. “Previous studies have examined how the brain is affected by Covid-19 using a univariate approach, but ours is the first to use a multivariate, data-driven approach to link these changes to specific Covid-19 characteristics (for example fever and lack of oxygen) and outcome (disability level).”

The analysis showed patients with higher levels of disability had lower gray matter volume in the superior, medial and middle frontal gyri at discharge and six months later, even when controlling for cerebrovascular diseases. Gray matter volume in this region was also significantly reduced in patients receiving oxygen therapy compared to patients not receiving oxygen therapy. Patients with fever had a significant reduction in gray matter volume in the inferior and middle temporal gyri and the fusiform gyrus compared to patients without fever. The results suggest Covid-19 may affect the frontal-temporal network through fever or lack of oxygen.

Reduced gray matter in the superior, medial and middle frontal gyri was also present in patients with agitation compared to patients without agitation. This implies that gray matter changes in the frontal region of the brain may underlie the mood disturbances commonly exhibited by Covid-19 patients.

“Neurological complications are increasingly documented for patients with Covid-19,” said Vince Calhoun, senior author of the study and director of TReNDS. Calhoun is Distinguished University Professor of Psychology at Georgia State and holds appointments in the School of Electrical and Computer Engineering at Georgia Tech and in neurology and psychiatry at Emory University. “A reduction of gray matter has also been shown to be present in other mood disorders such as schizophrenia and is likely related to the way that gray matter influences neuron function.”

The study’s findings demonstrate changes to the frontal-temporal network could be used as a biomarker to determine the likely prognosis of Covid-19 or evaluate treatment options for the disease. Next, the researchers hope to replicate the study on a larger sample size that includes many types of brain scans and different populations of Covid-19 patients.

Hace unos dias vi una serie de gifs de Marie Kondo explicando que a la hora de ordenar nuestra ropa debemos elegir la que nos produce felicidad, y para no sentirnos mal por la ropa que queremos botar, agradecer el tiempo que estuvo esa prenda estuvo con nosotros y dejarla ir..

Esto me llamo la atención y luego en Netflix descubri que habia una serie de ella, donde va a casas de personas y las ayuda a organizar. Me gusto su método y quise compartir algunos de sus consejos con ustedes. Quien sabe. Siempre se aprende algo 😉

My mum taught me to fold clothes this way! She used to work in clothing retail when she was young and apparently it’s a way to minimise unwanted creases on the front of your clothes.

Cudjo Lewis, the last surviving captive of the last slave ship to bring Africans to the U.S.

https://www.history.com/news/zora-neale-hurston-barracoon-slave-clotilda-survivor?utm_campaign=Echobox&utm_medium=Social&utm_source=Twitter#link_time=1525373347

It’s so significant too that this narrative was collected by Zora Neale Hurston, one of the greatest authors and anthropologists of her time. She was shunned by the “gatekeepers” of both of these professions, largely because of her Blackness, her womanhood, and her uncompromising commitment to honoring and showcasing both in her works. She died penniless and alone in a state-run institution in 1960. All of her works had gone out of publication by then. It took more than a decade before she was rediscovered. A young author by the name of Alice Walker had come across her work and was deeply inspired by it. “In 1973, after an exhaustive search, Walker came across Hurston’s unmarked grave in Ft. Pierce, Fla. She purchased a headstone for Hurston’s tomb and had it inscribed “A Genius of the South.“”

It is through Zora Neale Hurston’s pioneering sacrifice, and the acceptance of that inheritance by Alice Walker that we have found this missing piece of our history. Without the courageous and unfailing work of Black women, we wouldn’t have Cudjo Lewis’s story. We are slowly regaining a narrative that’s been hidden from us, one that continues to be lied about. Trust Black women to lead the way.

@japanese-randomstuff @japanese-langblr @glotpoly @atejapan @japaneseblr @learnjp @aringoaday @ilostmyheartintokyo @nodoyodobenkyou @playwithletters

…and on a final note, some tips:

Be consistent. From my experience, Japanese is a language that if not studied constantly, can be easily forgotten

Use separate notebooks/folders for grammar and vocabulary. You will thank me for this one later.

If you want your kanji/katakana/hiragana/whatever it is that you are writing to look neat, follow the stroke order ! ! !

Quizlet is your best friend when it comes to remembering vocabulary

Hope this helped someone!! Also if you have any questions/need some advice on where to begin, please don’t hesitate to hmu @sttudy

How I Use OneNote for University

Hey, all! I thought I’d share how I use OneNote, for any students who might want to use it for school organization. I have used this since the beginning of my university career and have found a method that works for me, after nearly three years.

I provide templates for what I use as .one files that can be imported into OneNote, and you’re free to use & modify them however you wish.

Semester Calendar Template: Download

Customized Syllabus Template: Download

Cornell Outline Template: Download + Outline inspired by How to Use Cornell Cornell Note-Taking Method on OneNote by @strive-for-da-best

As a student with learning disabilities, I found that using a computer, rather than writing everything out, is the best method for me to learn. I type up notes in class so as to not worry about keeping up with a professor, handwriting, or neatness. OneNote is my favourite note-taking application for this, because it’s essentially an upgraded version of Word that’s free and syncs automatically across devices. When my computer crashed, I was still able to access my notes online.

OneNote isn’t all typing. You can use it on a tablet or use a drawing tablet, in my case, to handwrite notes for a more natural feel. A very efficient way of taking notes is to import the lectures slides in OneNote and to write directly on them. I found that very useful in math-heavy courses, such as statistics and chemistry. The equation tool, while nifty, isn’t efficient.

By no means whatsoever is this the only way to use OneNote! In fact, I’d recommend you find a way that works for you, because while this may be highly organized, it takes a bit of set-up time and is tailored specifically to my needs. You can use my example as inspiration, but play around with it! The beauty of OneNote is that it can be used in a variety of different ways.

Tsitsi Masiyiwa. A true hero.

rashemibabe

I was about to say wtf is her NAME! I wish they’d stopped doing that and also what country of Origin!

seals-need-love-to-live

ALSO her husband’s business went under when they were married, they were completely penniless together, and then they built that business up and he made millions TOGETHER. She didn’t just marry some millionaire. Y'all have no trouble talking about Melinda Gates (using her name, not saying she’s just some woman who married a millionaire) but can’t do it with Tisitsi?

Tsitsi has a doctorate. She sits on the boards of PATH and END Fund, and is a founding member of the African Philanthropy Forum. She’s pretty incredible.

twodotsknowwhy

She’s from Zimbabwe, not “Africa.” We don’t call Melinda Gates “North American”
