Multidrug-resistant fungal infections are an emerging global health threat. Figuring out how fungi evade treatments offers new avenues to counter resistance.
Cells move their genetic material from one place to another in the form of RNA.

Making sure RNA molecules are in the right place at the right time in a cell is critical to development and normal function. Researchers are figuring out exactly how they get to where they need to go.
Maybe the first life on Earth was part of an ‘RNA world.’

Fossil evidence of how the earliest life on Earth came to be is hard to come by. But scientists have come up with a few theories based on the microbes, viruses and prions existing today.
Exercising regularly, and spending time outdoors can improve your health.

Cancer cells are ‘cheaters’ that do not cooperate with the rest of the body. Certain microbes in your diet can either protect against or promote tumor formation by influencing cell cooperation.
The lung-on-a-chip can mimic both the physical and mechanical qualities of a human lung.

Counterintuitively, cells move faster in thicker fluids. New research on breast cancer cells explains why, and reveals the role that fluid viscosity plays in metastasis.
Cryo-electron tomography shows what molecules look like in high-resolution – in this case, the virus that causes COVID-19.

Many microscopy techniques have won Nobel Prizes over the years. Advancements like cryo-ET that allow scientists to see the individual atoms of cells can reveal their biological functions.
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.

Cell membranes are a basic structure common to most living organisms – but they can be hijacked.
The proteasome is a cellular machine that chews up misfolded and unwanted proteins, and can promote cell death, making it an interesting target for cancer treatment.

Faulty cellular waste management machinery can lead to cancer and neurodegenerative diseases, but researchers are also targeting this machinery to treat these diseases.

Pioneered by the Human Cell Atlas consortium, our understanding of the human body is about to be transformed – and with it, the way we treat and prevent disease
It is possible to grow cells from a skin sample in a Petri dish and transform them into neurons in about a month.

Healing is a complicated process. As people age, higher rates of disease and the fact that old cells lose the ability to divide slow this process down.
