Christian Maugee — PhD Candidate, University Of Florida — From Patient To Genetics Research Pioneer

From patient to genetics research pioneer — christian maugee — phd candidate, university of florida.

Christian Maugee is a PhD Candidate at the University of Florida, in Genetics and Genomics (http://www.vulpelab.net/graduate-and-undergrad-students.html where his research explores how gene expression differs in the hearts of individuals with Friedrich’s Ataxia (FA), a rare, progressive neurodegenerative disease. His work could lead to new insights into the cardiac complications that can be associated with FA and how to potential treat them better.

Christian’s dissertation work is focused on identifying gene modulators of the transcriptional phenotype of FA in human induced pluripotent stem cells differentiated into cardiomyocytes (hPSC-CMs). He accomplishes this through use of a novel method: Perturb-seq — a CRISPR screen coupled with single cell RNA sequencing (scRNA-seq) readout.

Christian is driven by much more than academic curiosity, as he brings a unique and deeply human perspective to his work as someone living with FA. He doesn’t just study the challenges faced by those with disabilities; he lives them. His work is not only informed by data and theory, but by resilience, authenticity, and a commitment to making research more inclusive and impactful.

In the lab, Christian loves mentoring, and outside of the lab he loves fundraising and raising awareness for FA, mainly through FARA (https://www.curefa.org/) and MDA (https://www.mda.org/disease/friedreic…).

MRI age clocks reveal how each organ ages differently and predict who develops disease or lives longer

Researchers developed seven MRI-based biological age clocks across major organs using UK Biobank imaging, linking each to proteins, metabolites, genetics, disease risks, mortality, and cognitive decline. These organ-specific age gaps reveal how uneven aging shapes vulnerability to conditions such as diabetes, hypertension, and dementia, opening new paths for precision prevention and clinical trial stratification

A logical calculus of the ideas immanent in nervous activity

Because of the “all-or-none” character of nervous activity, neural events and the relations among them can be treated by means of propositional logic. It is found that the behavior of every net can be described in these terms, with the addition of more complicated logical means for nets containing circles; and that for any logical expression satisfying certain conditions, one can find a net behaving in the fashion it describes. It is shown that many particular choices among possible neurophysiological assumptions are equivalent, in the sense that for every net behaving under one assumption, there exists another net which behaves under the other and gives the same results, although perhaps not in the same time. Various applications of the calculus are discussed.

Cryosphere Chat ft. Emil Kendziorra — Tales from Biostasis 2025, Our Near Death Experiences

The gang catches up with Emil Kendziorra after the Biostasis 2025 conference at the European Biostasis Foundation. Watch it on YouTube here. Topics covered include:

• How to get a Tomorrow Bio ambulance in your hometown.
• Tomorrow Bio’s plan to collect brain samples to check ultra-structure preservation in its cryonics patients — and how it will respond to what it finds.
• What’s new and what’s next for Tomorrow Bio.
• Our near death experiences.

A Tiny Peptide Can Freeze Parkinson’s Proteins Before They Turn Toxic

As Parkinson’s disease progresses, harmful protein clumps build up in the brain, blocking communications between neurons and killing them off – but what if we could prevent these clusters from forming?

Researchers led by a team from the University of Bath in the UK have achieved just that in a basic worm model of Parkinson’s. They engineered a peptide, a small amino acid chain, to essentially keep a protein called alpha-synuclein locked in its healthy shape. This prevented the misfolding that leads to clumps.

The potential treatment checks several important boxes: it’s durable, and it can survive inside cells without causing any toxic side effects.
