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...

Musk And Time

"Elon Musk Is TIME's 2021 Person of the Year"

I'm not an uncritical Elon Musk fanboy. 
But I am glad to see Time Magazine giving this year's recognition to someone whose primary claim to fame is what they've achieved in the private sphere, as opposed to how good or bad they've been as a political ruler over others.
From the article: 
He’s a player in robots and solar, cryptocurrency and climate, brain-computer implants to stave off the menace of artificial intelligence and underground tunnels to move people and freight at super speeds.

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.
