Breakthrough in Fly Brain Research Paves Way for Understanding Human Cognition

Scientists have achieved a monumental breakthrough by mapping the fly brain, revealing the position, shape, and connections of all its 130,000 cells and 50 million intricate connections. This research represents the most detailed analysis of an adult animal's brain to date and is being hailed as a "huge leap" in understanding human cognition.

The fly's brain, though tiny, supports a range of complex behaviors, including walking, hovering, and even producing mating songs. Dr. Gregory Jefferis, a leader in the research from the Medical Research Council's Laboratory of Molecular Biology in Cambridge, emphasizes that this mapping could illuminate the mechanisms behind thought processes in humans. He noted the lack of understanding about how brain cell networks facilitate our interactions with the world.

Despite humans having a million times more neurons than the fruit fly, the new wiring diagram, or connectome, will aid scientists in deciphering cognitive functions. Published in the journal Nature, the imagery showcases a stunningly complex structure that reveals how a small organ can perform powerful computational tasks.

Dr. Mala Murthy, co-leader of the project from Princeton University, stated that this connectome will be transformative for neuroscientists, allowing for a better understanding of healthy brain function and the potential to compare it with malfunctioning brains.

Dr. Lucia Prieto Godino from the Francis Crick Institute supports this view, highlighting that while simpler organisms like worms and maggots have had their connectomes mapped, the fly’s intricate wiring is a significant achievement. This success paves the way for mapping larger brains, potentially leading to a human connectome in the future.

The research team has successfully identified separate circuits for various functions, illustrating how movement-related circuits are positioned at the base of the brain, while those responsible for vision are located on the sides. The study not only identifies these circuits but also explains their connections, enhancing our understanding of neural processing.

Interestingly, researchers are already applying these circuit diagrams to understand why flies are so hard to catch. The wiring related to vision quickly processes incoming threats, sending signals to the fly's legs to jump away faster than conscious thought.

To create the wiring diagram, researchers used a technique involving slicing the fly brain into 7,000 incredibly thin pieces, photographing each slice, and digitally reconstructing the whole. They employed artificial intelligence to analyze neuron shapes and connections, correcting over three million errors manually.

Dr. Philipp Schlegel from the Medical Research Council highlights that this data serves as a comprehensive map of brain connectivity, akin to a detailed Google Maps for the neural networks. This combined information will facilitate countless discoveries in neuroscience in the coming years.

While a human connectome remains elusive due to the complexity of the human brain, researchers believe that advancements in technology may allow for such mapping in about three decades. The fly brain research marks a significant step toward unlocking the mysteries of human cognition and understanding our own minds better.

The study was conducted by the FlyWire Consortium, an international collaboration of scientists dedicated to advancing neuroscience.

what really fries me about people who use chatgpt on their homework in my classes is they get the wrong answer and then they text me and i tell them how to do it and they’re like “😱😱 how did you know how to do that ??” well maybe if you opened the slides instead of rushing to jerk off ai you would’ve realized that the professors tell you how to do what they want you to do 😭😭 you dumb fucks FKDKDNJSND LIKE ??

Julian and Keiko headcanons because Keiko gets sidelined so much and deserves the world and I wish we got to see them interact more

when they get stumped on their respective projects, they'll do late night work sessions together and bounce their research off each other to see if the other can help them figure out where the problem is. they'll do this in person when theyre both on the station, but also over call if one of them is away, and after the O'Briens move back to Earth

they edit each other's papers (Keiko marvels at Julian's ability to spell out complex chemical compounds with his eyes closed, and somehow use 'their' instead of 'there') (in his defense he wrote that bit at 4 in the morning after going 2 straight days without sleep) (she threatens to sedate him)

Julian sometimes brings back plants from planets they explore in the Gamma Quadrant and gives them to Keiko. sometimes he does it because the plant has medicinal properties and the two of them can do a joint research project, but most of the time he does it just to give her a nice gift

when Miles goes away for particularly dangerous missions, Julian will keep Keiko company and help keep her mind off of it. sometimes she has trouble sleeping because shes so worried, so he'll hang around and start rambling on about whatever he's currently working on until she falls asleep. he jokes he's boring her to sleep, but it actually means a lot to her

they have a weekly tea date. this is their prime gossip time. sometimes Jadzia is invited

when Keiko's mad at Miles she'll rant to Julian about it. Julian learned very quickly that this is not a time where advice is wanted, so he sits back and lets her get it all off her chest, because she really just wants someone to listen and let her blow off some steam

Julian makes a concentrated effort to learn more about plant husbandry and care after the incident where he accidentally killed some of Keiko's prized plants because he actually does feel very bad about it

Julian hovered over Keiko nearly as bad as Miles did when she was pregnant with Kirayoshi (and then he hovered over her even more after the pregnancy transfer, and he wouldnt tell anybody why, but Keiko knew it was because nearly losing her shook him up pretty bad)

when Julian gets outed for being augmented, Keiko goes to him and gives him the tightest, warmest hug he's ever gotten in his entire life

Julian gets invited to girls nights with Keiko and Molly (steady surgeon's hands make him the best one to paint nails) (he pretends to complain but he loves it)

anytime Julian has to go away for a scientific conference of any kind, if he gets to bring someone with him, his first choice is always Keiko

in short: theyre besties they told me so themselves <3

"and im gonna go buy party cups" awwww I do lowkey kind of feel bad for fabian this season like. obviously the more highly magical of the group have been favored while figuring out these god mysteries but. fabian's social maneuvering has been important too and his growth as a friend and his success on the owlbears. I don't think he's getting enough credit! especially with the election being so pivotal for the ritual!!! give him some praise!!!

We found a new antibiotic target in bacteria!!

It took almost 4 years, but the fruits of my postdoc research are finally here! In our paper (with me as the first author), just published in Nature Communications, we decipher a working mechanism of an antibiotic that targets the membrane of bacteria in an unprecedented way!

enhanced PDF: https://rdcu.be/dgj2d web version: https://lnkd.in/eRpxr4jg

And how does it work?

The antibiotic AMC-109 first self-assembles into stable aggregates with a cationic surface. These aggregates then specifically target bacteria cells and insert into their membrane.

You can see the process how we simulated it in a computer on the figure below. Grey-Blue is the antibiotic, Red-Yellow are lipids that together form a membrane.

@jmelcr did this awesome simulation work! You are an amazing scientist, jmelcr! I love you and it seems our collaboration did not ruin our marriage. Not yet, anyway 😄.

After insertion into the bacterial membrane, the antibiotic dissolves membrane nanodomains affecting membrane function without formation of any pores or holes in the membrane.

Below is the series of high-speed atomic force microscopy images that shows the process of dissolution of membrane nanodomains. Yellow are the membranes extracted from bacteria laying flat on a hard surface (black). The membranes contain nanodomains (bright yellow) that are important in living bacteria for its survival. Addition of antibiotic dissolves them.

More studies will follow that use this new target in bacteria giving us an advantage over untreatable superbugs. I will keep you posted. And... keep your fingers crossed. It's research after all, so we never know if and how well it's going to work.

here's the thing about DB Cooper

a lot of people think or thought he died during the initial heist

but there were NUMEROUS copy cat heists of people doing the same thing in the immediate aftermath and did jumps that were in similar or WORSE conditions but they ALL survived (and were caught)

so i need people to stop being amazing at this idea that DB Cooper survived that jump because it's not as incredible because so many fuckin amateurs did worse and also survive those same jumps

In September, a world-first human trial of a drug that can regenerate teeth will begin at Kyoto University Hospital. The drug has shown success in animals, growing new teeth with no significant side effects. Lead researcher Katsu Takahashi hopes the treatment will be available commercially by 2030.

The drug deactivates the USAG-1 protein, promoting tooth growth. The trial will first focus on adults with missing molars, then expand to children with congenital tooth deficiency and eventually to those with partial edentulism. If successful, the treatment could be available for all patients with missing teeth within six years.

(via World-first tooth-regrowing drug will be given to humans in September)
