The word "vacuum" may conjure the image of empty space. Maybe you think of a region far outside the solar system without planets, debris, gas clouds or light. According to quantum theory, however, a vacuum is never truly empty. Quantum mechanics extends the Heisenberg uncertainty
The word "vacuum" may conjure the image of empty space. Maybe you think of a region far outside the solar system without planets, debris, gas clouds or light. According to quantum theory, however, a vacuum is never truly empty.
Quantum mechanics extends the Heisenberg uncertainty principle—which states that we cannot measure the position and the velocity of an object exactly at the same time—to a vacuum. The result is that a vacuum can never be still.

A protein that regulates mRNA decoding can itself be regulated with implications for understanding cancer
Decoding of messenger RNA (mRNA) occurs during translation, the vital cellular process that builds proteins. Errors in this process are known to lead to cancer growth. Scientists at St. Jude Children's Research Hospital identified how one factor involved in mRNA decoding can be a

Waves alter Antarctic polynyas by breaking up surrounding sea ice
Polynyas are one of Antarctica's great counterintuitive features: recurring areas of open water surrounded by vast expanses of sea ice. These unusual environments are hot spots for sea-ice production, ocean–atmosphere exchange and biological productivity. They are commonly mainta
