A schoolteacher in the midst of receiving a full pe'a, the traditional Samoan tattoo generally worn by males.
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.
Johan Jarnestad / The Royal Academy of Sciences
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.
Using the right metaphor in science is important.
We know about A, B and O - but there are hundreds of other blood groups.
Why do we have blood groups and how are they discovered?
Computers may play an important role in preparing us for the next viral outbreak – whether flu or Ebola.
UW Institute for Protein Design
This antivirus software protects health, not computers. Researchers are beginning to combat deadly infections using computer-generated antiviral proteins – a valuable tool to fight a future pandemic.
HIV plays hide and seek with the body’s immune system to evade detection. But we can learn from its tactics to make a range of vaccines against infectious diseases.
Researchers are learning how HIV hides from the immune system to develop a new generation of vaccines for seemingly unrelated diseases, like the flu.
Can some people's immune systems defeat Ebola virus before it has a chance to cause disease?
For viruses like dengue, being injected with the pathogen as in a vaccine can open the door to secondary infections.
Our immune system protects us but when it comes to some mosquito-borne disease, it can work against us. What are the implications for the development of a Zika virus vaccine?
Antibody attacking a bacterium.
Why it's important to fund blue-skies research.
Allergies are becoming more frequent in the western world.
Allergies are reactions caused by the immune system as it responds to environmental substances that are usually harmless. But we don't yet have a cure or the ability to prevent them from developing.
The immune system protects us from the constant onslaught of viruses, bacteria and other types of pathogens we encounter throughout life. But it can sometimes misbehave.
Isolating the antibodies.
Immunotherapy has joined anti-retroviral drug therapy as a means to combat HIV.
Primates - human and non-human - can be infected by Ebola.
As viruses go, Ebola is one that strikes particular fear. It’s infectious and four out of the five identified strains can cause severe hemorrhagic fever, which in later stages leads to bleeding from the…
Vampire bat venom could be the new ingredient in drugs to treat stroke and high blood pressure. A team of researchers have…
Microbubbles could be used as a less invasive method of detecting heart disease or a risk of stroke before they become serious…
A variant of a protein naturally used to manufacture the essential amino acid histidine has been designed and successfully…
