Biophysics Definition and 154 Threads

I'm a final year (4th year) applied physics student studying in Ireland, and I've spoken with one of my professors about a possible PhD study. The study he offered me was to do with nanorods and their ability to kill/wave off bacteria, taking inspiration from the Lotus leaf. I've attached what...

Hello all! I'm a physics student, planning to apply for a biophysics PhD program once I finish my undergrad. My main topics of interest are neuroscience and microbial communities. Originally I was just in physics because I liked the approach, but statistical mechanics showed just how...

TL;DR Summary: Briefly i'm asking for guidance through self-studying biophysics. Hello everyone, i've almost finished my bsc in physics and i got intrigued by biophysics, although my university doesn't provide courses for the subject. I wanted to get a grasp of the subject by myself but...

Hi, I was wondering if a Magnetic Resonance (+contrast) can in some way modify the structure of artificial chordae used in heart surgery. My first answer would be "No". There ain't any medical article about that. Also (as far as i know) I don't think magnetic field can break chemical bond, so it...

Hello, I am currently working on an idea for a possible future masters or PhD in cellular biology, however my idea is currently just a passion project. For it to work, I would need to learn how to predict and make a specific protein to do a specific function, in this instance I need to use it to...

Hello, I am originally a medical doctor and now doing a PhD in neuroscience. I have no formal physics / math training beyond high school level but I self-studied single variable and multivariable calculus as well as differential equations from MIT's OCW website, did examples, exams etc. I also...

Hey y'all! I'm about to enter my second year of undergrad as a double major in Physics and Vocal Music. I am still exploring a lot of what physics has to offer, but I'm very intrigued by biophysics. I recently found a paper on the mechanics behind cell differentiation during embryonic...

Hello, I’m looking to apply for CSME/computational physics/biophysics PhDs in America starting in September 2024. I'm a bit scared about physics departments just because whilst I have mechanics, QM and Stat Mech I have never taken any atomic/electrodynamic classes. I would like to know if my...

I'm interested in biophysics but I don't know much biology or chemistry to begin with, yet I know a good bit of math and physics. What topics in biology and chemistry should I cover before reading a book on biophysics?

Hello everyone, I'm a undergrad student at the State University of Maringa, from Brazil. In three semesters I'll graduate with a bachelor degree. And I want to do a master in biophysics, probably in another country and I think that's it.

I was wondering if it is of any value for someone interested in physics/Biophysics grad school and a Biophysics career to be working in a biology lab? I'm an undergraduate physics major concentrating in biophysics in the US and I have an offer to work in a cancer biology lab. It's very much...

The structure of the cell membrane is depicted as being formed from a bilayer of phospholipids with their hydrophilic portions pointing outwards and their hydrophilic portions facing each other. But as I look at the histology of the epithelial layer of the epidermis or mucous membranes, I am...

From an excel file I can get the probability of each energy state Εi and I saw at Wikipedia that the probability of each energy is proportional with e^−Εi/KT, from this I find the energy of every micro state. Also from the formula which I found on a paper I can get a curve like the curve...

Are there areas of studies which could be characterized as an interface of biological physics and quantum physics? Does such an interface even exist?

What can you do with a masters degree in biophysics?

Hi. I'm a physician trying to understand the micromechanics of lung injury due to overdistension. The basic idea is that overstretching of the plasma membrane of the lung epithelial cell causes "stress failure" --> i.e. plasma membrane rupture --> cell death. The concepts of stress, strain, and...

Hello, I'm a college undergraduate sophomore interested in eventually getting a Ph.D. in biophysics or computational physics. I have the chance to take several graduate math classes in the next two years, and I was wondering which ones would be the most useful for me in the future. They are...

Hey y'all, I posted here a while back, but here goes. I'm looking for biophysics schools/labs with realistic assessments of how likely it is I'll get in. Also looking for forums to post to besides this one :) Summary: Senior undergraduate at UIUC, dual degree in Physics, CS + Math. 3.7 GPA...

Are there any ways particle physics can impact biology? Specifically, being able to use methods from theoretical physics to study biological systems (possible physiology related).

Hey all, So I'm about to be a senior at a US school, and likely want to do grad school. I'm posting here because my interests are really sort of disparate and don't really share a theme. I like dynamics, stat mech, doing stuff on computers, and doing stuff with my hands... Anyway, here's a...

Saltatory nerve conduction occurs because of myelination of nerve fibers. This is done by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system. From what I understand, it happens because depolarization of the membrane at an unmyelinated area of the...

I have problem understanding these techniques with reference to the question: a. PCR b. Southern blotting c. Reverse transcriptase PCR d.Western blotting My attempt: d. Western blotting is not the right method here because it doesn't detect DNA or RNA transcript. b. Southern blotting can be...

Hi, so some background. I am an undergrad just now finishing my second year in my biophysics degree. I wanted to go into biomedical engineering, I understand that this is an insanely competitive field. My GPA is embarrassingly low. There are some reasons behind it, but everyone has their reasons...

What math and physics is needed for biophysics research? Specifically having to do with medical applications. I am undergrad student interested in physics and medicine.

I saw the roadmap of my university of and there is no calculus for biophysics, as soon as there is no calculus for medicine, as for example there is in the US. My question is if there is calculus for biophysics in Europe and in the US. Adendum: there is only calculus in Brazil for medicine in...

Previously I made this post, and soon after realized how woefully unprepared I am to approach such a topic. As stated in the post, I think my best use of time would be to gain background knowledge on the topic before attempting a project, but now I think I've found a better focus as to what...

As I said before in a other thread (I don't remember if it was this section). To do a postgraduate in Theoritical Biophysics or in a astrobiology, I need to have a minor, or a major is enough?

Hi folks, My name is José Ricardo, I study at the Federal University of Rio de Janeiro (1st period). As the majority of the academics, always there is one who wants to follow a career. I'm doing major in Physics. I want to teach? Yes, I do. But I want to follow the research as well. I have...

A chord played on a piano is multiple different pitches, each at a different frequency, played simultaneously. The ear hears this as separate sounds. The cochlea of the ear is organized by tone (tonographic organization), from highest to lowest frequency. So a triad chord will stimulate three...

I am trying to compare an experiment on spinal changes due to zero-g in astronauts. Researchers simulated zero-g spinal elongation by suspending human subjects so that no part of their body touched the ground. This figure shows the % change in disc thickness for each subject compared to data...

I have spent the past few months incredibly conflicted. I just finished my freshman year of undergrad (at a 4-year American university) and I have discovered Biophysics, a field which I really want to pursue. However, I still love math and want to continue with my Applied Math major. I'm afraid...

Hi all, I am trying to learn more about this field. Whether you work or have worked in this area or not, I would like to know where Soft Matter is going in terms of theory and applications. Thanks, A.D. *I apologize in advance if there are already many threads specifically addressing this...

Hi everybody! So I got a Masters in physics (precisely - biophysics) 5 years ago. Then attempted to get a PhD, realized that research and academia don't feel right to me and quit. Now I'm 28. Despite the lack of the doctoral degree, working in the lab gave me many skills. Biomedical engineering...

Hello. I am a teacher about to wrap up his fifth year in May. I started at the very bottom, teaching at risk and worked my way up with the help of my former teachers. I now teach AP Physics 1 and IB Mathematics SL. The whole experience has left me jaded. I gave it my all: my personality, my...

Hello, Is anyone here familiar with teaching Biophysics or biology/life-science focused physics courses in a two-year institution? We have problem of low enrollment in the traditional physics course - i.e. both in algebra-based and calc. based physics courses! But we have very healthy...

Hi! I am starting my Master's in Applied Physics at the TU Delft next week and I have yet to decide a research track (i.e. specialization). I have narrowed my options down to bionanoscience and quantum nanoscience. Of these two, which would be better? Of course, 'better' is a vague term, so what...

There are two optically transparent tissues in the human body: the cornea and the lens. But how they achieve this transparency is different, and both in turn appear to achieve this differently than in other optically clear materials like glass. The transmission of light through glass or other...

Well I have a few questions, for the past few months and weeks, my parents have been constantly bugging me to be a doctor [I just became a senior, like today; I will be applying to college in a few months, so I need to be thinking about majors and stuff]. My problem is I don’t hate medicine, its...
