Immunity to COVID-19 may be complicated. Here are the promises and pitfalls of antibody tests.
'Nanobodies' produced by the llama immune system can neutralise the virus that causes COVID-19.
Rapid blood tests for coronavirus could fill a large gap in knowledge.

Expanding coronavirus testing is one of the most important tasks public health officials are tackling right now. But questions over accuracy of the two main types of tests have rightly caused concern.
The science is far from certain, but it appears at least a proportion of people who have had COVID-19 will be protected from another infection – at least initially.
Even if you’re feeling fine, you might be infected by the SARS-CoV-2 virus that causes COVID-19.

Your body can be infected and fight off SARS-CoV-2 without your ever noticing.
Testing blood provides answers about who has been infected.

After your body fights off an infection, antibodies remain in your blood. Two researchers explain how tests identify these antibodies and what the data can be used for.
Antibodies capturing a virus.
Using antibodies to trap the virus could create near-instant pregnancy test-style kits.

Before a vaccine is available to teach your immune system to ward off the coronavirus, maybe you can directly use molecules that have already fought it in other people.
Evidence from a new study could help scientists develop drugs to neutralise the 'allergic antibodies' that cause anaphylaxis.
The science of making reagents, the chemicals needed for the COVID-19 finger-prick test.
A test that detects antibodies against the coronavirus behind COVID-19 would reveal those people who have already encountered the virus - and therefore who might be ok to resume normal life.
New rapid testers could look a bit like a pregnancy test.
Scientists are working hard to develop reliable tests that can detect anti-virus antibodies from past infection.
Tens of millions of people worldwide suffer from migraines, according to the World Health Organization.
Many migraine headaches are triggered by certain foods. Recently, a lot of attention has focused on gluten. An expert explains how a piece of bread can cause pain in your head.

An anthropologist works in American Samoa, taking advantage of the island's longstanding tattoo culture to tease out the effects tattoos have on the body's immune function.
Are you exhausted? Your immune cells might be too.
The cornerstone of our adaptive immune system is the ability to remember the various infections we have encountered. Quite literally, if it doesn’t kill you, it makes your immune system stronger.
More than a year after a groundbreaking liver transplant doctors still can’t say if the recipient is HIV-positive or not.
A liver transplant from an HIV-positive living donor to an HIV-negative recipient is possible, but there are still gaps in our knowledge.
Scientists are now using evolution to create designer proteins for therapies and industrial processes.

Nature doesn't always make the things we need so three Nobel Prize winners figured out how to fast-track evolution in the lab to create medicines, biofuels and industrial chemicals for modern life.
Getting rid of this scourge is nothing to be sneezed at.
