assumption

The origin of magnetic fields in galaxies is still a mystery to astronomers. Popular theories suggest continual strengthening over billions of years.

New research, however, contradicts this assumption and reveals that young galaxies also have strong magnetic fields.

Chondritic meteorites have a similar chemical composition to the sun and are therefore reliable witnesses as to what the solar nebula, from which the planets formed, was composed of.

This can be used to deduce what the Earth consists of chemically. However, researchers have now discovered that strictly speaking this fundamental geological assumption is not true.

Psychologists find evidence that it's not. People act in their own best interests, according to traditional views of how and why we make the decisions that we do.

However, psychologists have recently found evidence that this assumption is not necessarily true. In fact, most of us will act in the best interest of our team -- often at our own expense.

Most people assume that women voters will automatically support female candidates with their votes, a phenomenon known as "gender affinity effect." Is that an accurate assumption?

And does political party affiliation impact the effect?
