In the 1970s four spacecraft began their one-way trips out of our Solar System. As the first human-built objects to ever venture into interstellar space, NASA chose to place plaques on Pioneer 10 and 11 and golden records ...

Ancient oral biome points to overall health

When a baby puts something from the floor in their mouth, we panic, but the mouth already contains thousands of bacteria. Now a team of researchers is looking at archaeological remains for an example of how Japanese oral ...

New imaging technology could help predict heart attacks

Researchers have developed a new intravascular imaging technique that could one day be used to detect coronary plaques that are likely to lead to a heart attack. Heart attacks are often triggered when an unstable plaque ruptures ...

Extracting information from ancient teeth

There's a surprising amount of information stored in the hardened plaque, or calculus, between teeth. And if that calculus belongs to the remains of a person who lived in ancient times, the information could reveal new insights ...

How damaging proteins form

Alzheimer's disease and Parkinson's disease are both examples of amyloid diseases, where malfunctioning proteins accumulate to form fibrils and larger aggregates called amyloid plaques. In the journal Biophysical Chemistry ...

Decreased iron levels in seawater make mussels loosen their grip
