Academic publishing is perhaps the greatest scam perpetrated on intelligent people

1) Write grants (unpaid)
2) Do research
3) Write papers
4) Peer review (unpaid)
5) PAY up to $12K to publish
6) Need publications to get grants (back to step 1)

Publishers: 38% profit margins

A simple guide to how mitochondria work. 4️⃣ primar jobs

Mitochondria are more than the “powerhouse of the cell.” They’re multitasking organelles that control energy, stress, genetics, and even cell survival. Here are the 4 primary jobs they do:

1️⃣ ATP Generation (Energy Production)

Mitochondria convert glucose, fats, and amino acids into acetyl-CoA, which enters the TCA cycle and electron transport chain (ETC).

The result: ATP, the energy currency for everything from nerve signals to muscle contractions.

🟢 Example: Every time you move or think, mitochondria are fueling the process.

2️⃣ ROS Balance - i.e., redox control

As mitochondria make ATP, they also generate reactive oxygen species (ROS) damaging byproducts.

Antioxidant enzymes (like catalase, SOD, glutathione peroxidase) keep ROS under control.

Too much ROS = oxidative stress → cell injury or death.

🟢 Example: Exercise trains mitochondria to better balance ROS, which is one reason it’s so protective.

3️⃣ mtDNA Maintenance (genetic stability)

Mitochondria have their own DNA (mtDNA), which encodes key ETC proteins.

Damage or mutations in mtDNA reduce energy output and contribute to diseases.

mtDNA mutations accumulate with age, linking mitochondria to neurodegeneration and aging.

🟢 Example: Mitochondrial DNA damage is a hallmark in Alzheimer’s and Parkinson’s disease.

4️⃣ Membrane Dynamics (fission & fusion)

Mitochondria constantly split (fission) and merge (fusion) to adapt to stress and demand.

This dynamic reshaping controls quality, removing damaged mitochondria (mitophagy) and keeping networks healthy.

🟢 Example: Impaired fission/fusion is seen in metabolic disorders and neurodegenerative disease.

Mitochondria don’t just make energy. They balance oxidative stress, protect genetic integrity, and constantly remodel themselves to keep cells alive. Supporting mitochondrial health means supporting the foundation of cellular life.

The Lipid Brain Atlas is out now! If you think lipids are boring and membranes are all
the same, prepare to be surprised. Led by Luca Fusar Bassini with Gioele La Manno's lab, we mapped membrane lipids in the mouse brain at high resolution.

Mi tía quedó ciega como a sus 30s y no tenía posibilidad de volver a ver hasta este año, casi 40 años después, que le dieron una chance con nuevos procedimientos. Confió en el proceso y luego de varias cirugías hoy me vió por primera vez 🥲🙏🏼🫶
