Scientists can now synthesize mRNA in the lab and package it in lipid nanoparticles that deliver the synthetic mRNA to cells. This gives the cell the instructions to become its own pharmacy. (Unsplash+/Getty Images)

How nanomedicine gets inside your cells and treats you from the inside out

Nanomedicine prompts RNA to make protein-based drugs to treat diseases. Now we can fine-tune protein production by dialling it up or down, creating personalized medicine on an invisible scale.

RNA is key to the dark matter of the genome − scientists are sequencing it to illuminate human health and disease

Researchers are embarking on the RNA equivalent of the Human Genome Project, including sequencing all the chemical modifications that make cells unique.

Molecular ‘fossils’ offer microscopic clues to the origins of life – but they take care to interpret

A protein historian and evolutionary biochemist found that a protein sequence present across all known life didn’t form as researchers previously thought it did.

Found dead in the snow − how microbes can help pinpoint time of death for forensic investigations in frigid conditions

An accurate estimate of when someone died is a critical part of forensic investigations. In extremely cold conditions, molecular biology can provide critical information where the naked eye cannot.

Iron fuels immune cells – and it could make asthma worse

Asthma attacks can result from immune cells overreacting to a harmless allergen. Tamping down iron levels in certain immune cells can help control their activity.
