Tandem means having two in a row. and mass spectrometry is a method used to analyze samples to look at chemical makeup by looking at charge-to-mass signatures of individual atoms in a sample. Putting two mass spectrometers in a row increases the sensitivity of this method so that ions that are close in mass can be told apart. A great analogy and explanation can be found in this Youtube video.

Samuel Pierpont Langley (1834-1906) was an American astronomer, physicist and inventor. His research on solar and lunar radiation greatly influenced Arrhenius.

Arrhenius used data from Langley's 1890 publication "The Temperature of the Moon" as the basis for his model.

Joseph Fourier (1768-1830) was a French scientist and mathematician who studied heat transfer. He theorized that Earth's atmosphere could act as a thermal insulator by absorbing heat (radiation) emitted by Earth's surface.

Arvid Hogbom (1857-1940), a Swedish geologist, was a colleague of Arrhenius, a professor at Stockholm University and a member of the Physical Society.

De Marchi seems to refer to the ability of the atmosphere to let through all wavelengths of radiation. He probably focused on the ability of water vapor in clouds to reflect incoming solar radiation, reducing how much solar energy reaches Earth's surface.

When Arrhenius discusses transparency in relation to his model, he focuses on the ability of water vapor to absorb infrared radiation and re-emit it back toward Earth's surface.

Luigi De Marchi was an Italian meteorologist. The work quoted here is from his prize-winning essay for a competition on the causes of the Ice Age.

A measure of the shape of an ellipse, how far it is flattened from a circular shape. An orbit with low eccentricity is almost circular, whereas an orbit with high eccentricity is highly elliptical.

Items 3, 5 and 9 in De Marchi's list make up the Milankovitch Cycles, which affect how much energy Earth receives from the Sun and how that energy is distributed over the globe.

Also called "precession", this refers to the orientation of Earth's rotational axis relative to its position in its orbit around the Sun.

Items 3, 5 and 9 in De Marchi's list make up the Milankovitch Cycles, which affect how much energy Earth receives from the Sun and how that energy is distributed over the globe.

Protoplasmic astrocytes are a subset of astrocytes that are located in the gray matter (which consists mostly of cell bodies) in the brain. They have many complex processes that can contact blood vessels and neurons.

Unbiased clustering is a statistical approach to make sense of large sets of data. It allows scientists to group together ("cluster") genes that are similar to one another.

Synaptic signaling refers to how neurons communicate with one another.

A projection called an axon from the pre-synaptic neuron touches or "synapses on" the dendritic projections of the post-synaptic neuron. Chemicals called neurotransmitters are released from the pre-synaptic neuron and mediate responses in the post-synaptic neuron.

The transcriptome refers to the total set of RNA transcribed from DNA.

In single-nucleus RNA sequencing, the nucleus (which contains DNA and nascently transcribed RNA) is isolated from a single cell. The isolated RNA undergoes RNA-sequencing, in which the RNA is broken up into fragments. Using a database, these fragments are then aligned to specific transcripts.

The neocortex is the part of the brain that in humans is associated with higher level functions such as cognition and language.
