Common Vitamin May Reduce Buildup of Alzheimer's Proteins, Study Finds

New research has linked levels of vitamin D in midlife with toxic tangles of tau protein that accumulate in the brains of those with Alzheim

New research has linked levels of vitamin D in midlife with toxic tangles of tau protein that accumulate in the brains of those with Alzheimer's disease. A statistical analysis of blood samples and brain scans from 793 adults showed that the more vitamin D in someone's system in middle age, the lower the amount of tau protein tangles they tended to have years later. The finding comes from an international team of researchers, and while it doesn't prove direct cause and effect, it suggests an association that's worth looking at.

hey everyone! i know i’ve been gone for A While, but i just turned in a big scholarship application (cgrs-m for any other canadian researchers out there) so now seems like a good time for an update

earlier this year, i finished a very cool structural biology class that made me realize that - as neat as it is - i absolutely do not want to do that kind of research myself. since then, i started my master’s in a cell biology lab that works on lipids. i’m so excited about my project, but i also don’t want to say too much about it since it’s very specific and niche project, and i don’t really want my research to be associated with my tumblr account

all this has made me realize just how much i don’t know what i’m doing on here talking about protein structures. i have a couple friends who are doing projects focused on determining protein structures and even working with machine learning to make structural predictions, who would be immensely more qualified to talk about any of this. i don’t want to give the impression that i’m an expert where i am not and accidentally share incorrect or misleading information.

on the other hand, i am also discovering just how much of grad school involves not knowing what you’re doing. its been months and i’m very much still confused about so many things. i was recently talking to two people who just finished their PhDs and they both told me that they still feel that way. so, if you’re ever feeling lost and overwhelmed at any point in science, just know that you’re not alone! and to be honest, science would be so much less fun if it all made sense

so, i’ve decided to embrace not fully knowing what’s going on and come back to this blog to try and answer your questions and make some funky shapes!! no promises about how regularly i’ll post, but i plan to try and queue up a few peptonominations over the weekends that will come out throughout the week. in the meantime, enjoy this mess i made by accidentally pasting the nucleotide sequence of my gene of interest into alphafold instead of the amino acids:

thanks to everyone who stuck around for your patience <3

This plastic is made from milk and it vanishes in 13 weeks

Milk protein and clay team up to create a plastic-like film that vanishes in soil in just 13 weeks.

As concerns grow about the environmental and health impacts of plastic waste, scientists are accelerating efforts to develop safer, biodegradable alternatives. At Flinders University in South Australia, several research teams are working on new materials designed to reduce pollution from single use plastics. In a recent study published in Polymers, researchers created a thin, flexible film using calcium caseinate, a commercially available form of casein, the primary protein found in milk. They blended it with modified starch and bentonite nanoclay, then added glycerol and polyvinyl alcohol to improve durability and flexibility. The goal was to produce a material that performs like conventional plastic while being far more environmentally friendly.
