Nature Outlook: Extracellular RNA
RNA — the molecule best known for its part in translating genetic code into protein-making instructions — is finding a new role in medicine. Key to this is that microRNA, once thought to exist only in cells, has been shown to travel outside cells to tissues all over the body through the blood, under the protection of ‘extracellular vesicles’...
Inside the stem-cell pharmaceutical factory
Vesicles secreted by stem cells might give clinicians a safer and simpler alternative to cell therapy, but researchers are still grappling with how best to prepare and study these tiny particles...
Could tracking RNA in body fluids reveal disease?
Tests that detect extracellular RNA to spot cancer, heart disease and other conditions are in development
Handheld Ultrasound Devices Are Speeding Diagnosis of COVID-19
Doctors can triage and monitor patients faster—and sometimes more accurately—with the aid of the pocket-size machines
New Design Helps N95 Mask Wearers Breathe Easier
