      This is a very current topic, and something I've been wondering about.
  • based on variations in the volume of different brain regions as well as based on how those regions communicate with one another across brain networks.
    • margogramiak
       
      That's interesting. I'm excited to hear about what those differences are.
  • ...7 more annotations...
  • They then compared the MRI data of participants who reported often feeling lonely with those who did not.
    • margogramiak
       
      Makes sense
  • Researchers found the default networks of lonely people were more strongly wired together and surprisingly, their grey matter volume in regions of the default network was greater.
    • margogramiak
       
      Why?
  • The fact the structure and function of this network is positively associated with loneliness may be because lonely people are more likely to use imagination, memories of the past or hopes for the future to overcome their social isolation.
    • margogramiak
       
      This makes sense, but it's always really sad to think about.
  • In lonely people, the structure of this fibre tract was better preserved.
    • margogramiak
       
      Again, why?
  • "In the absence of desired social experiences, lonely individuals may be biased towards internally-directed thoughts such as reminiscing or imagining social experiences.
    • margogramiak
       
      That makes sense. It also makes sense that it would affect the brain.
  • Loneliness is increasingly being recognized as a major health problem, and previous studies have shown older people who experience loneliness have a higher risk of cognitive decline and dementia.
    • margogramiak
       
      This is obviously a very current issue because of quarantine
  • the urgency of reducing loneliness in today's society,
    • margogramiak
       
      but how is that possible in a climate like this?

  • Electrodes implanted in these patients' brains help their surgeons precisely identify the seizure foci and also provide valuable information on the brain's inner workings, Lega says.
    • margogramiak
       
      Wow, that's pretty cool.
  • What the team found was exciting: Not only did they identify a robust population of time cells, but the firing of these cells predicted how well individuals were able to link words together in time (a phenomenon called temporal clustering). Finally, these cells appear to exhibit phase precession in humans, as predicted.
    • margogramiak
       
      That's super interesting. I can see why this would be helpful research
  • In addition, while rats are actively exploring an environment, place cells are further organized into "mini-sequences" that represent a virtual sweep of locations ahead of the rat. These radar-like sweeps happen roughly 8-10 times per second and are thought to be a brain mechanism for predicting immediately upcoming events or outcomes.
    • margogramiak
       
      Wow. I think how this article is putting super complex ideas into words that are easier to understand.
  • it was unclear how the hippocampus was able to produce such sequences.
    • margogramiak
       
      I'm sure there will be specific research on this eventually
  • hocolate milk
    • margogramiak
       
      why chocolate milk I wonder...
  • However, taking a closer look at the data, the researchers found something new: As the rats moved through these spaces, their neurons not only exhibited forward, predictive mini-sequences, but also backward, retrospective mini-sequences. The forward and backward sequences alternated with each other, each taking only a few dozen milliseconds to complete.
    • margogramiak
       
      How can information like his be applied to treating dementia though?
  • "In the past few decades, there's been an explosion in new findings about memory,"

    • margogramiak
       
      face transplant?
  • The transplant from an anonymous donor took place at Boston’s Brigham and Women’s Hospital in July.
    • margogramiak
       
      I know a little bit about these surgeries. They are revolutionary!
  • ...14 more annotations...
  • whose face was disfigured in an attack by her ex-husband,
    • margogramiak
       
      :(
  • More than 40 patients worldwide have received face transplants, including 16 in the United States. None of the American patients had lost their donor faces until Tarleton.
    • margogramiak
       
      So few people.
  • She really got lucky.”
    • margogramiak
       
      good for her. She deserved to be lucky.
  • rejected his donor face eight years after his first transplant underwent a second
    • margogramiak
       
      I don't know anything about this stuff, but that seems like a very delayed rejection.
  • She really wanted to try one more time,” said Pomahac, who led the 20-hour, second surgery. A team of around 45 clinicians removed the failing transplant and then prepared sensory nerves and blood vessels in the neck for the surgical connection. The face was then transplanted and Tarleton will gain sensory and motor function in the coming months.
    • margogramiak
       
      wow!
  • a much better tissue match.
    • margogramiak
       
      What constitutes a good match? Blood type? Skin tone? What are important factors?
  • “The pain I had is gone,” she said. “It’s a new chapter in my life. I’ve been waiting for almost a year. I’m really happy. It’s what I needed. I got a great match.”
    • margogramiak
       
      Awww I'm so happy for her!
  • “When you look at most organ transplants, there is a shelf life,” Gastman said. “We are getting to the point where these face transplantations are hitting against the maximum number of years someone can have one in.”
    • margogramiak
       
      The transplant surgeries are so new that they are now seeing how long they last.
  • Tarleton was burned on over 80% of her body and blinded in 2007 when her estranged husband, Herbert Rodgers, beat her with a baseball bat and doused her body with lye because he thought she was seeing another man.
    • margogramiak
       
      Oh my gosh. I'm glad she gets this new opportunity.
  • The first transplant transformed Tarleton’s life.
    • margogramiak
       
      I'm sure it did. So many people take "normal" appearances for granted.
  • don’t get stared at so easily.”
    • margogramiak
       
      I can't imagine having to think about that.
  • She was added back on when the state allowed elective surgeries to resume.
    • margogramiak
       
      Must be very recent!
  • But by last year, the face was failing. She began experiencing scarring, tightness and pain because of a loss of blood flow to her face. Black patches appeared on her face. Her eyelids contracted and her lips began disappearing, making it difficult to eat. She was mostly housebound and resumed taking strong pain medications.
    • margogramiak
       
      If they didn't do another transplant, what would another remedy be?
  • “It is strange. I am not going to lie,” she added. “I’ll have to get used to it. My sister will have to get used to it. It takes a while for my friends and family to get used to what I look like now.”
    • margogramiak
       
      I can't imagine my whole appearance changing on a dime.

How To Fight Deforestation In The Amazon From Your Couch | HuffPost - 0 views

  • If you’ve got as little as 30 seconds and a decent internet connection, you can help combat the deforestation of the Amazon. 
  • Some 15% of the Amazon, the world’s largest rainforest and a crucial carbon repository, has been cut or burned down. Around two-thirds of the Amazon lie within Brazil’s borders, where almost 157 square miles of forest were cleared in April alone. In addition to storing billions of tons of carbon, the Amazon is home to tens of millions of people and some 10% of the Earth’s biodiversity.
    • margogramiak
       
      all horrifying stats.
  • you just have to be a citizen that is concerned about the issue of deforestation,
    • margogramiak

    • margogramiak
       
      great!
  • to build an artificial intelligence model that can recognize signs of deforestation. That data can be used to alert governments and conservation organizations where intervention is needed and to inform policies that protect vital ecosystems. It may even one day predict where deforestation is likely to happen next.
    • margogramiak
       
      That sounds super cool, and definitely useful.
  • To monitor deforestation, conservation organizations need an eye in the sky.
    • margogramiak
       
      bird's eye view pictures of deforestation are always super impactful.
  • WRI’s Global Forest Watch online tracking system receives images of the world’s forests taken every few days by NASA satellites. A simple computer algorithm scans the images, flagging instances where before there were trees and now there are not. But slight disturbances, such as clouds, can trip up the computer, so experts are increasingly interested in using artificial intelligence.
    • margogramiak
       
      that's so cool.
  • Users simply select the squares in which they’ve spotted some indication of human impact: the tell-tale quilt of farm plots, a highway, a suspiciously straight edge of tree line. 
    • margogramiak
       
      I could do that!
  • Look at these nine blocks and make a judgment about each one. Does that satellite image look like a situation where human beings have transformed the landscape in some way?” Inman explained.
    • margogramiak
       
      seems simple enough
  • It’s not always easy; that’s the point. For example, a brown patch in the trees could be the result of burning to clear land for agriculture (earning a check mark for human impact), or it could be the result of a natural forest fire (no check mark). Keen users might be able to spot subtle signs of intervention the computer would miss, like the thin yellow line of a dirt road running through the clearing. 
    • margogramiak
       
      I was thinking about this issue... that's a hard problem to solve.
  • SAS’s website offers a handful of examples comparing natural forest features and manmade changes. 
    • margogramiak
       
      I guess that would be helpful. What happens if someone messes up though?
  • users have analyzed almost 41,000 images, covering an area of rainforest nearly the size of the state of Montana. Deforestation caused by human activity is evident in almost 2 in 5 photos.
    • margogramiak
       
      wow.
  • The researchers hope to use historical images of these new geographies to create a predictive model that could identify areas most at risk of future deforestation. If they can show that their AI model is successful, it could be useful for NGOs, governments and forest monitoring bodies, enabling them to carefully track forest changes and respond by sending park rangers and conservation teams to threatened areas. In the meantime, it’s a great educational tool for the citizen scientists who use the app
    • margogramiak
       
      But then what do they do with this data? How do they use it to make a difference?
  • Inman was surprised how willing people have been to spend their time clicking on abstract-looking pictures of the Amazon.
    • margogramiak
       
      I'm glad so many people want to help.
  • we have still had people from 80 different countries come onto the app and make literally hundreds of judgments that enabled us to resolve 40,000 images,
    • margogramiak
       
      I like how in a sense it makes all the users one big community because of their common goal of wanting to help the earth.
