Snowball Fights In Art
"Snowball Fights in Art".
I especially liked some of the Asian artwork. And the photograph, "Photograph of Princeton students after a snowball fight between freshman and sophomores, 1893"

Memory Storage In Brains
"Where is Memory Information Stored in the Brain?"
Within the scientific research community, memory information in the brain is commonly believed to be stored in the synapse - a hypothesis famously attributed to psychologist Donald Hebb.
However, there is a growing minority who postulate that memory is stored inside the neuron at the molecular (RNA or DNA) level -- an alternative postulation known as the cell-intrinsic hypothesis, coined by psychologist Randy Gallistel. In this paper, we review a selection of key experimental evidence from both sides of the argument...

Tiny Camera
"Researchers shrink camera to the size of a salt grain". (Via G.F.)
While a traditional camera uses a series of curved glass or plastic lenses to bend light rays into focus, the new optical system relies on a technology called a metasurface, which can be produced much like a computer chip. Just half a millimeter wide, the metasurface is studded with 1.6 million cylindrical posts, each roughly the size of the human immunodeficiency virus (HIV).
Each post has a unique geometry, and functions like an optical antenna. Varying the design of each post is necessary to correctly shape the entire optical wavefront. With the help of machine learning-based algorithms, the posts’ interactions with light combine to produce the highest-quality images and widest field of view for a full-color metasurface camera developed to date.
