Covid -19 new hope from blood tests

Bbc World Service
About this episode

Research from New York examining the blood of people who have recovered from Covid – 19 shows the majority have produced antibodies against the disease, The researchers hope to soon be able to establish whether this confers long term immunity as with more common viral infections.

And Research in Berlin and London has identified biomarkers, minute signs of the disease which may help clinicians identify who is likely to develop severe symptoms and what kind of treatment they might need.

Mutations have been much in the headlines, these are a natural processes of evolution and not just in viruses, but the term is misunderstood, two studies focusing on different aspects shed some light on what mutation in SARS-CoV-2 really means.

Also What is the smallest particle of matter? How does radiation affect our bodies? And, how is particle physics useful in our everyday lives?

We take on particle physics questions from listeners all over the world. Marnie Chesterton and Anand Jagatia get help from particle physicists from the Large Hadron Collider at CERN and medical physicist Heather Williams.
