Fairy Circles in the Outback

Whimsically classified as fairy circles, these strange hexagonal patches of land never over-lap and can only truly be appreciated with an aerial view. Resembling the same pattern as honeycomb, they can be found in the millions along a 1,800km (more than 1,000 miles) long area of South Africa extending from Angola south toward the Northwestern Cape province. Most of them, however, are located in the Namib desert. Individually they appear as rings of tall grass enclosing barren centers of red earth, which can measure between 2m (7ft) and 20m (65ft) in diameter.

Wires and supercapacitors constructed inside living plants

In November 2015, the research group presented results showing that they had caused roses to absorb a conducting polymer solution. Conducting hydrogel formed in the rose’s stem in the form of wires. With an electrode at each end and a gate in the middle, a fully functional transistor was created. The results were recently presented in Science Advances.

One member of the group, Assistant Professor Roger Gabrielsson, has now developed a material specially designed for this application. The material polymerizes inside the rose without any external trigger. The innate fluid that flows inside the rose contributes to create long, conducting threads, not only in the stem but also throughout the plant, out into the leaves and petals.

Wait, explain to me this mechanic where you have to give up your Palestinian ID if you want to go to Palestine?

It’s a really complex system and I cannot explain it all in one post, but I will try to summarize it. 

Every Palestinian residing in the Palestinian Territories has an ID that’s issued by Israel via the PNA

And you need the ID to get a passport, open a bank account, get married, own property, have the right to live there, have the right to enter/exit the part of the Palestinian Territories you’re living in, etc. 

And there are three type of IDs issued to Palestinians living in the Palestinian Territories, one for Palestinian residents in Gaza (like mine), one for the West Bank, and one for Palestinians in East Jerusalem. (the one for East Jerusalem is issued by Israel directly)

They slightly differ from each other, so for example, since I’m from Gaza and I carry an I.D. from Gaza, I can’t enter/live in the West Bank or East Jerusalem, though these areas are considered a Palestinian territory. 

And if a Palestinian from the West Bank someway how managed to visit Gaza and went back home to the West Bank, they will face consequences. (I’m not sure what are the consequences, but I heard there are consequences)  

And if I remember correctly, a Palestinian with an East Jerusalem I.D. cannot marry a Palestinian with a West Bank or Gaza I.D. and if they do, they won’t be able to grant their spouse a permit to live in Jerusalem. 

And if a Palestinian with an East Jerusalem I.D. lives outside Jerusalem for about 7 years their I.D. will be revoked, making them lose their right to live their even if they were born there and their family lived there for centuries.

So basically it’s not the PNA or Hamas that decides who’s a resident of Gaza and who’s not. It’s Israel that decides that, though Israel claims it ~completely separated itself~ from Gaza. Same goes for the West Bank and East Jerusalem.

Sexism in Bronze Age China left signs of malnourishment etched on women's skeletons

Upheaval in farming methods in the Bronze Age Eastern Zhou Dynasty meant that life took a major turn for the worse for women’s social status and health, a new study has find. Neolithic China during the Yangshao period (5000-2900 BCE) wasn’t such a bad time for women, at least compared with men.

In agricultural communities along the Yellow River, women could eat the same amounts of animal products and were, roughly speaking, equally well-nourished.

But by the time of the Eastern Zhou Dynasty (771-221 BCE), all that had changed. Women had less access to valuable high-protein animal products, and their skeletons have revealed marked stress and increasing height disparities with men, reflecting malnourishment, according to a paper published in the journal PNAS.

That's why it's called the 'Ramallah bubble'? I had no idea, I've always heard the term and never actually questioned it. I'm Palestinian and I wasn't even aware of that. I've never really been over there except when I was a baby but wow. Thanks for the insight

It’s also called the bubble because it’s where the PNA is headquartered and rules, the PNA likes to think it has full autonomy, and sovereignty but that fantasy ‘bursts’ whenever the IDF raids the city or blocks roads surrounding it

Here’s what sleep deprivation is doing to your body

Not getting enough sleep? Just one week of sleeping fewer than six hours per night can lead to serious health issues, including the modification of over 700 genes, reports the Huffington Post on a study published in PNAS last year. Other symptoms of chronic sleep deprivation include everything from bloodshot eyes to quadrupled stroke risk. This infographic fromHuffington Post’s Alissa Scheller explains.

Hello! Totally irrelevant to the context of your blog, but I came across your most recent nail post on my dash and read that you were a psychiatric nurse. I'm interested in the nursing field (I'm a male) and was wondering if you could please give me a little insight on what being a psychiatric nurse is like? How is it different from being a bedside nurse in say, med-surg or ICU? What drew you into psychiatry? Hopefully I'm not bothering you too much with these questions!

When I was in nursing school, about 90% of the students could not wait for the psych clinical rotation to be over (some actively hated it, others were just uncomfortable or indifferent).  But 10% totally loved it, and I was one of those.

It’s not completely unrelated to other areas of nursing— I’m still assessing patients, implementing physician orders, charting like crazy, passing meds, and arguing with other members of the treatment team.  And I do deal with medical problems as they come up (feels like every week I’m examining someone’s hand for possible fracture after they punched a wall).

But it’s also very different from other types of nursing.  One of my major responsibilities is to manage the therapeutic milieu, which is a fancy way of saying that I make sure the hospital setting is as helpful to our patients as it can be.  Are there enough structured activities? Do the kids feel safe?  Is the unit too noisy or chaotic feeling? Who is fighting with who?  Who’s trying to fuck who?  Who needs new shoes, or a notebook, or a special type of shampoo? 

This also involves overseeing our PNAs (psychiatric nursing assistants), and making sure that our whole direct-care team is being consistent and therapeutic in how we interact with patients.  Are we setting the right limits, are we giving enough encouragement, are we maintaining healthy boundaries, do our patients feel heard?  It’s not unlike parenting— we’re teaching the kids we work with all kinds of unspoken things, and we need to make sure we’re modeling the right kind of behavior.  Interpersonal skills are important in all kinds of nursing, but it’s really the bread and butter of psych nursing.

I also do a lot of crisis management.  Maybe two kids are threatening to kill each other and I need to find a way to diffuse the situation.  Maybe someone is feeling suicidal and I need to talk them through that and make sure they don’t have opportunities to act on their urges.  Maybe someone has stripped their clothes off and is trying to break the windows with a chair.  There are not necessarily rules for dealing with the situations that come up, which is different from other areas of nursing. On the one hand this allows for a lot of creativity and independence, and makes my work life feel like an adventure.  On the other hand, sometimes I feel totally lost and have no fucking clue what to do or say.

It’s a meaningful job, but also profoundly sad at times.  It’s an exciting job, but also a draining and sometimes dangerous one.  I know it’s not for everyone, but personally I love it.
