    Sat - Would you rather get away with lying every time or always know that someone is lying?

    I tend not to lie much, even white lies to spare someone’s feelings. I’ll tell the truth, but I do think there’s a way to tell the truth without it being mean or harsh! I’d rather know when someone is lying, though I can see why this might not be the brilliant skill it seems to be….

    Sun -  Would you rather read minds or accurately predict future?

    Predicting the future. If I want to know what someone is thinking, I’ll ask them, and I don’t want to accidentally stumble across something i’m not meant to see in someone else’s head. Predicting the future would be nice to be able to better prepare for things, but I do enjoy a slight sense of mystery in my life! 

    I ended this week with a surprisingly fast run (and a surprisingly painful side stitch) and doing more physchem. I’ve made a dent in this module, and I really hope I continue this productivity towards exams! 🌻

    I only have two more finals to go!!! (ft. Snufkin on my laptop) 

    This are the most challenging weeks for me because I feel the irresistible urge to be lazy or do other things because I’m almost completely on summer vacations. However, I’m trying as hard as I can to keep reviewing everyday. 

    I’ve also been having the incredible impulse to write a part of my oldest oc’s story and I actually kind of started it, but I don’t want to dive onto it just yet because it’s one way to distract me from actually studying. Anyway, I’ll probably come back to it after my finals are over on Thursday.

  • Over the last year I’ve worked as a peer mentor helping freshman navigate into the college realm. This was my on-campus job that one of our freshman programs offers to upperclassmen to continue being a part of the program after their first year. I absolutely loved it and highly recommend mentoring for anyone who loves to help like I do (also extroverts, man y’all would love mentoring!).

    I would love to be able to continue mentoring this summer as I have the time to do so and know that there’s plenty of y’all out there that will start university in the fall under some really different circumstances! I’d love to be here as a friend and a mentor to help you through the process a little easier! My DMs are open for anyone who would like to start mentoring beginning mid-June through DMs and later through Skype or Zoom if you would like!

    Here’s some things about me!

    • I’m a second-year university student.
    • I study human physiology (similar to human biology but more in-depth anatomy & physiology topics).
    • I am a pre-Physician Assisting (pre-PA) student.
    • I originally came into university as a biology pre-med major.
    • I have now taken too many lab classes, so I can tell you what lab research consists of!
    • If everything goes according to plan, I will be studying abroad in Australia next February. :D
    • I go to a fairly large, fairly popular school on the West Coast!

    I’m super passionate about helping others, and I hope that I can help you during this time! Maybe if this goes alright I’ll wrangle up some studyblr friends to mentor those who aren’t STEM majors aha!

    Happy studying!

  • Its all cz of bonding in chemistry (in life as well)

    Basics of chemistry is bonding….
    So, why do the reactions occur as they occur? Can you mix just hydrogen and oxygen in a gas chamber and get the water that you drink?
    Whatever around us we see all things are made up of small molecules…which in turn includes atoms, their shape, their bonding , their nature weather it is accepting or donor…etc etc..
    In short there is a chemistry behind everything out there…and in basic of all that there is a big word - BONDING
    here are basic bondings of chemistry…
    without this bondings chemistry can not be imagine…these are the heart of chemistry and every chemist…

    same is applicable in real life also…

    when your basic bonding, understanding, needs of each other are clear..you can have whole world in your palm…but if it is lacking of bonding, communication, sharing, understanding than don’t think that will go more…
    definatelly you have to have your basics clear than only you can have relation as well as chemistry (🤔🤔🤔) in your hand….

    Fri - Would you rather speak all languages or be able to speak to all animals?

    Speak all languages, I love learning languages but I’m very bad at it and I don’t enjoy being bad at speaking them! After my exams i’m going to try and learn some Italian though! 🌻

  • “Oh, non mi vergogno di questa dipendenza, di questa, se vuole, folle, sciocca passione. No, io non ho ancora mai amato; ora soltanto capisco che cosa significa. Finora, nella mia vita, tutto era stato solo prologo, solo attesa, solo passatempo, solo tempo sciupato, fino a quando ho conosciuto lei, fino a quando l'ho amata, veramente e profondamente amata. Mi si è detto, se non proprio in faccia, quanto meno dietro, che non faccio che guastare, che pasticciare la maggior parte delle cose. Può darsi, ma non avevo ancora trovato ciò in cui posso mostrarmi maestro. Vorrei vedere chi fosse capace di superarmi nell'arte di amare. Certo, è un'arte miseranda, ricca di sofferenze e di lacrime; però me la sento così naturale, così mia, che ben difficilmente vi rinuncerò.”

    J. W. Goethe, “Le affinità elettive”, 1809.

    Cosmic Rays as the Source of Life’s Handedness

    By Susanna Kohler

    You might expect living cells to be composed of a random soup of materials — but look closely and you’ll find they’re built from molecules with distinct orientation preferences.

    How did life’s preferred “handedness” arise?

    Living Single-Handedly

    Billions of years ago, perhaps on the barely solidified crust of young Earth, life somehow arose from non-living matter.

    Today, we still haven’t solved the puzzle of how this transition from non-living to living occurred — but nature has left behind some helpful clues, including the intriguing geometry of life’s building blocks.

    Many organic molecules come in two forms: left-handed and right-handed versions that are mirror images of each other.

    Just as you can’t put a left-handed glove onto your right hand, the mirror images of these chiral molecules are distinct and cannot be superimposed.

    But while the pre-biological soup of material on early Earth contained both left-handed and right-handed forms of chiral molecules, living organisms are homochiral: they’re built almost exclusively from left-handed amino acids and right-handed sugars and nucleotides, which preferentially construct right-handed DNA and RNA.

    A Cosmic Influence

    What determined the handedness of Earth’s life?

    Was it a random initial disequilibrium — perhaps an overabundance of right-handed nucleotides trapped in a prebiotic nursery — that was then copied to all subsequent life?

    Or might the bias only have arisen later, driven by an outside source?

    In a new study, scientists Noemie Globus (New York University and Flatiron Institute) and Roger Blandford (Stanford University and KIPAC) explore how cosmic rays may have shaped the evolution of early life forms.

    Mutating for Survival

    Cosmic rays are highly energetic, charged particles that careen in from space and slam into the Earth’s atmosphere, producing a cascade of secondary particles that can reach the planet’s surface.

    Irradiation from cosmic-ray cascades is thought to drive gene mutation in DNA — an exploratory process that is critical for evolution.

    Many successive gene mutations in the earliest stages of life likely allowed proto-life forms to adapt to their environment, increasing their complexity and their chances of survival.

    Intriguingly, the physical force that governs cosmic-ray cascades naturally introduces a preferential handedness in the secondary particles that reach the planet’s surface.

    Could this handedness somehow have introduced homochirality for life forms?

    Pick a Hand

    Globus and Blandford propose a model in which prebiotic chemistry produced both of the mirror versions of DNA and RNA.

    As these proto-lifeforms worked to self-replicate and evolve, cosmic rays rained down, introducing minor mutations.

    The handedness of the cosmic rays caused a slight difference in the mutation rate of the two different chiral forms, giving a tiny edge to the right-handed DNA.

    Over many generations of self-replication, this small chiral bias eventually resulted in early life dominated by a single handedness.

    Can we test this model? We might find supporting evidence from laboratory experiments that simulate the influence of cosmic-ray irradiation on bacteria mutation rates.

    And, of course, we can hope that we’ll one day explore life’s building blocks in samples from asteroids and other planets, further pinpointing what led to life as we know it.

    CENTRE IMAGE….This generic amino acid exists in both a left-handed and a right-handed form: all the same things are attached in the same order, but the two forms are mirror images and cannot be superimposed. If both forms exist, why is life built from only left-handed amino acids?

    LOWER IMAGE….In this schematic, the authors illustrate how the decay of a cosmic ray proton produces a shower of spin-polarized particles. When these particles reach the Earth’s surface, they affect right-handed and left-handed molecules differently, imparting a chirality bias. [Adapted from Globus & Blandford 2020]
