Seeing as how the Big Beautiful Bill just passed, here's are some websites that offer discounts on medications:
- GoodRx
- SingleCare
- Pharmacy Checker
- WellRx - this one compares prices across different pharmacies
Stay safe, everyone. Things are about to get much, much worse in the US.
so I haven't started work yet but i could really use some help. i got denied health insurance from the state and im currently waiting for ebt/snap benefits approval but idk i think im gonna get denied. and i recently got my Georgia license and had to pay like $34 and i still have these monthly fees from my bank account maintenance fees of like $12/$16 and my credit card monthly fees of like $40-$60 (which i don't use the cards anymore but trying to pay them off). so life just sucks right now and i could really use some help cause i have no income idk when my job start date is. so anything helps! even reblogs!

we should start making zines about cool research papers

August 16
My classes started last week and I'm very excited to be back. I'm taking a class about Autobiographical Documentaries and I think I've said this so many times already but it's one of my favorite genres to study. I just find it fascinating.
This week we watched the mockumentary David Holzman's diary (1967), directed by Jim McBride, and it's such a genius and absurd film. Next week, we'll be watching Ed Pincus' Diaries (1982) and I'm like hell yeah, bring those 4 hour films because this is the only way I'll ever watch them lmao.

A remote control for neurons
A novel material for controlling human neuron cells could deepen our understanding of cell interactions and enable new therapies in medicine.
A team led by researchers at Carnegie Mellon University has created a new technology that enhances scientists’ ability to communicate with neural cells using light. Tzahi Cohen-Karni, associate professor of biomedical engineering and materials science and engineering, led a team that synthesized three-dimensional fuzzy graphene on a nanowire template to create a superior material for photothermally stimulating cells. NW-templated three-dimensional (3D) fuzzy graphene (NT-3DFG) enables remote optical stimulation without need for genetic modification and uses orders of magnitude less energy than available materials, preventing cellular stress.
Graphene is abundant, cheap, and biocompatible. Cohen-Karni’s lab has been working with graphene for several years, developing a technique of synthesizing the material in 3D topologies that he’s labeled “fuzzy” graphene. By growing two-dimensional (2D) graphene flakes out-of-plane on a silicon nanowire structure, they’re able to create a 3D structure with broadband optical absorption and unparalleled photothermal efficiency.
These properties make it ideal for cellular electrophysiology modulation using light through the optocapacitive effect. The optocapacitive effect alters the cell membrane capacitance due to rapidly applied light pulses. NT-3DFG can be readily made in suspension, allowing the study of cell signaling within and between both 2D cell systems and 3D, like human cell-based organoids.

Systems like these are not only crucial to understanding how cells signal and interact with each other, but also hold great potential for the development of new, therapeutic interventions. Exploration into these opportunities, however, has been limited by the risk of cellular stress that existing optical remote-control technologies present. The use of NT-3DFG eliminates this risk by using significantly less energy, on a scale of 1-2 orders of magnitude less. Its biocompatible surface is easy to modify chemically, making it versatile for use with different cell types and environments. Using NT-3DFG, photothermal stimulation treatments could be developed for motor recruitment to induce muscle activation or could direct tissue development in an organoid system.

“This is an outstanding collaborative work of experts from multiple fields, including neuroscience through Pitt and UChicago, and photonics and materials science through UNC and CMU,” said Cohen-Karni. “The developed technology will allow us to interact with either engineered tissues or with nerve or muscle tissue in vivo. This will allow us to control and affect tissue functionality using light remotely with high precision and low needed energies.”
Additional contributions to the project were made by Maysam Chamanzar, assistant professor of electrical and computer engineering. His team’s core expertise in photonics and neurotechnologies assisted in developing the much-needed tools to allow both the characterization of the unique hybrid-nanomaterials, and in stimulating the cells while optically recording their activity.

“The broadband absorption of these 3D nanomaterials enabled us to use light at wavelengths that can penetrate deep into the tissue to remotely excite nerve cells. This method can be used in a whole gamut of applications, from designing non-invasive therapeutics to basic scientific studies,” said Chamanzar.
The team’s findings are significant both for our understanding of cell interactions and the development of therapies that harness the potential of the human body’s own cells. Nanostructures created using NT-3DFG may have a major impact on the future of human biology and medicine.

First post of the year, but these are old pictures I meant to upload but never got to. Spent two weeks in quarantine after coming back from DC for Christmas break. Ontario is in lockdown and I really miss the pool and the gym!!!
// Back to Kingston - Sam Kaiser //
reading classmates linkedin and hurting my own feelings, haha!

some essay plans :" they take so long to do ugh
210123// 15/100 days of productivity
today’s work & my wall rn (when did it get so cluttered??). didn’t feel the most productive today, but still managed to do the things from my to-do list
wrote the chapter i planned recently (3k words whooo)
studied korean
duolingo & drops
worked on the research report presentation
23rd January - Polar bear or penguin?
polar bear! they just seem…cuter?? but penguins are absolutely supreme animals too!
today’s focus: 6h
listening to: key, forever yours
I laugh every time I see this
