These photographs actually demonstrate some incredible synthetic biology in action. The researchers created and customized a system of 18 genes, broken into four parts: A light sensing gene to determine what color the bacteria should make, a “circuit” to process the signals, and a “resource allocator” which connects the circuits to the “actuator” that actually produces the pigment. The researchers created each of these pieces on their own and combined them together, according to the research published today in Nature Chemical Biology.
In his own later account (1946), Pauli describes how building upon Bohr’s ideas and drawing inspiration from others’ work, he proposed the idea that only two electrons (with opposite spins) should be allowed in any one quantum state. He called this ‘two-valuedness’ – a somewhat inelegant translation of the German zweideutigkeit (Pauli, 1925). The consequence was that once a pair of electrons occupies a low energy quantum state (orbitals), any subsequent electrons would have to enter higher energy quantum states, also restricted to pairs at each level.
Nurses with a greater range in their vocabulary have greater chances of communicating correctly than those who do not. In the operating room or on the floor, nurses need to be able to communicate effectively and having a robust vocabulary is a key part of being able to do that. As you prepare for the Vocabulary section of the HESI exam, be sure to study common vocabulary test words from both the real world and the medical field. The Vocabulary section of the test should take about 50 minutes and is part of the broader English English section asks a total of 55 questions, 50 of which actually count towards your score.
