Other techniques have different strengths and limitations: muscle biopsy gives access to a wider range of metabolites, but time-series measurements during exercise are very challenging, especially in clinical studies. So too are direct arteriovenous cannulation studies of muscle transmembrane fluxes (e....

For one thing, boat motors stress these animals out, so when they see a boatload of researchers headed their way, armed with biopsy darts, they're like "oh no, it's time to dip!" — days and many thousands of dollars can be wasted chasing a pod of whales. And the alternative, ...

Personalised vaccines to attack cancer cells By taking a biopsy of a patient's tumour and using this unique genetic information from their own tumour in combination with AI, scientists can design invidualised vaccines to activate the patient's immune cells to better recognize cancer cells, attack...
