3-D View of DNA

January 20, 2023

Photographer: Greg Parker

Summary Author: Greg Parker

Featured above is a 3-D view ( stereograph) of 2 and a half turns of
the DNA molecule. I put together this 3-D model from a
Cochranes of Oxford kit, and Dr. Brian May created the
stereograph – in mid-December of 2022. A DNA molecule consists of two
long polynucleotide strands or chains made up of four types of
nucleotide subunits. Each such molecule contains the biological
information responsible for making every species unique.

You can view the stereograph by:
1. Using the Cross-Eyed method
2. Using 3D prism glasses
3. Using B rian May’s OWL Stereoscope

High Tatras Halo Display

Summary Authors: Viktor Belicak; Jim Foster
Featured above is a panorama of an attention-getting halo display I
captured from the village of Zdiar in the very eastern part of the High
Tatras Mountains of Slovakia. It was taken just after sunrise on
December 18, 2022. The morning air was bitter cold -- temperature about
0 degrees F (-18 C). Sunlight shining through ice crystals
suspended in the air, within 100 m or so of the surface, created this
atmospheric wonder.

Easily visible here are the 22-degree halo, parhelia (sundogs)
and upper tangent arc (at top of 22-degree halo). Other arcs were
visible as the Sun rose higher. Displays such as this can on occasion
be observed at ski resorts when snow making equipment is used
to augment the natural snowpack. However, high winds lifting ice
crystals from the surface into the air or crystals free-falling
through the lower atmosphere may also result in these displays.

Photo details: Panorama made of 6 photos; ISO 100; 18mm; f 8; 1/400
second exposure.
