Astronomy: The quiet one

Astronomy and Astrophysics Quiet Sun Coronal Heating: Statistical Model

To describe statistical properties of solar coro-nal heating by microflares, nanoflares, and even smaller events, we consider a cellular automata model subject to uniform small scale driving and dissipation. The model consists of two elements, the magnetic field source supposed to be associated with the small scale hydrodynamic turbulence convected from the photosphere and local dis-sipation of...

Quiet Down Now: How Excitatory Neurons Inhibit One Another

Draped atop the brain like a wrinkled gray blanket, the cortex is responsible for much of what we perceive, think, and do. It is a couple of square feet in area and only a few millimeters thick, but its millions of neurons form trillions of synaptic connections, making it, hands down, the most complex piece of neural real estate on the planet. Its macroscopic convolutions can only hint at the c...

The quiet revolution

Sixty years have passed since Avery, MacLeod and McCarty published their landmark paper revealing DNA as the genetic material, writes Heather Dawes.

Ageism: the quiet epidemic.

Quantifying the quiet epidemic

During the late 20 century numerical rating scales became central to the diagnosis of dementia and helped transform attitudes about its causes and prevalence. Concentrating largely on the development and use of the Blessed Dementia Scale, I argue that rating scales served professional ends during the 1960s and 1970s. They helped old age psychiatrists establish jurisdiction over conditions such ...
