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.

Measuring multiple reactions on a single electrode with extraordinary sensitivity
A reaction on a single electrode can tell scientists a remarkable amount about the chemical nature and number of analytes involved. The challenge comes when they want to distinguish many reactions on the same electrode. After more than a decade of trying to overcome that limitati

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
