Red mitochondria in airway cells become coated with green SARS-COV-2 proteins after viral infection: Researchers discovered that the virus that causes COVID-19 damages lungs by attacking mitochondria.
COVID-19 causes lung injury and lowers oxygen levels in patients because the SARS-CoV-2 virus attacks cells’ mitochondria. This attack is a throwback to a primitive war between viruses and bacteria.

Alzheimer’s may not be primarily a disease of the brain. It may be a disorder of the immune system within the brain. Beta-amyloid may not be an abnormal protein, but part of the brain’s immune system.

The nomination of Judge Amy Coney Barrett has implications for how assisted reproductive technologies, which can prevent the transmission of disease from parents to child, are regulated.
Fluorescent human cells seen through a microscope.
Our cells may be small, but they are mighty. And they are made of lots of amazing stuff, from the DNA that tells your body how to grow, to mini skeletons that let cells move around.
Turkeys do a lot of standing and milling around, not a lot of flying.
Sit down to Thanksgiving dinner ready to amaze your companions with physiological facts about why different cuts of the turkey have different characteristics.
Australians can now have their say on the issues around mitochondrial donation.
Should Australia allow the creation of babies with DNA from more than two people? This reproductive technology could prevent babies being born with mitochondrial disease, so the simple answer is yes.
A study claims the first humans lived in a wetland around what is now northern Botswana.
It’s likely our species doesn’t actually have a single origin.
Terry Wahls before and after she changed her diet.
A doctor with MS who experimented with diet and other treatments has experienced a slowing of her decline – now she’s researching why it happened.
When it comes to reproduction, couple have more choices than ever before.
A ban on clinical trials involving gene editing rules out the controversial procedure done in China. But it also prevents procedures that could offer couples a chance for healthy children without genetic disorders.
We previously thought mitochondrial DNA could only be passed on by mothers.

Mathematical models can describe the many shapes of DNA, as well as cellular processes like DNA replication.
When a cell divides, mitochondria are randomly allotted to the resulting new cells.

The genes in our cells’ mitochondria are passed on in a different way than the vast majority of our DNA. New studies shed light on how the unique process isn’t derailed by mutations.
Rey (Daisy Ridley), in
Star Wars: The Last Jedi, ponders the light and dark sides of the Force.
Star Wars: The Last Jedi leaves many questions about the saga in a galaxy far, far away unanswered. Fortunately, biology may offer a insights on the Force, midi-chlorians, clones, and Rey’s lineage.
Is this how we got the sperm and the egg?
An ancient sexual conflict over mitochondrial inheritance may be responsible for the evolution of the two sexes as we know them.
Mitochondria live inside our cells but have a different genome. Here’s why.
To explain why we have a mitochondria, we have to go back about two billion years to a time when none of the complexity of life as we see it today existed.

It’s a landmark case but there are many unknowns.
Scientists thought they were closing in on one great new treatment but may have found another instead.
The annual ‘Living Landscapes’ procession is aimed at raising awareness of the Cedarberg’s KhoiSan cultural heritage.
Human population groups worldwide are highly homogeneous genetically. They are in fact 99.5% similar and their anatomical features vary in an uncorrelated fashion over the landscape.
