Researchers present a test that determines the amount of neutralizing antibodies within a short period of time.

Microglia keep the Toxoplasma gondii parasite in check in the brain. Microglia release an immune molecule that recruit immune cells from the blood to control the parasite.

Activating p38gamma, a naturally protective enzyme in the brain, may help to prevent the development of Alzheimer's disease symptoms. Researchers showed the naturally protective effects of p38gamma could be harnessed to ...

Laughing and smiling more might help to buffer against the effects of stress, researchers report.

Some male anglerfish fuse to the much larger females to mate - they can do so because they don't recognise their partner's tissue as foreign material that should be attacked

Large solar flares can put astronauts' health at risk and damage satellites, but we haven't had an early warning system for them - until now

A spacecraft is only as strong as its power source, which is why when NASA was designing its Perseverance Mars rover, the agency turned to radioactive plutonium.

Alzheimer's risk factors could be apparent as early as our teenage years, researchers reports. The risk factors disproportionately affect African Americans and include heart health problems, high cholesterol, diabetes, a...

When elephant seals go on long dives, they can reach thousands of metres below the ocean's surface - and the lice they carry with them can withstand the intense pressure there
