- Pink salmon — too much of a good thing? | Geophysical Institute
Pink salmon born in hatcheries, where professionals harvest eggs from wild salmon and rear them in captivity before releasing them in the ocean, have doubled in numbers since 1990 Russians have pink salmon hatcheries that increase numbers in the North Pacific and Bering Sea Alaskans run hatcheries in Valdez and other places in Prince William
- Creating Pink Sterling Silver: Chemistry and Heat Treatment Explained
The discussion centers on methods to create a pink hue in sterling silver, exploring both chemical adjustments to the alloy and potential heat treatment techniques Participants consider the implications of alloy composition and surface treatments in achieving the desired coloration One participant inquires about altering the chemistry of sterling silver, which is typically 92 5% silver and 7

- Understanding FTIR Peaks of PO4 Compounds • Physics Forums
The discussion focuses on the interpretation of FTIR (Fourier Transform Infrared Spectroscopy) peaks for PO4 (phosphate) compounds It establishes that multiple peaks at different wavelengths arise from various vibrational modes of the molecule, including stretching and bending vibrations Specifically, the modes v1, v3, and v4 correspond to distinct types of molecular vibrations, such as
- Why Does the Pink Color in a Titration Fade Over Time?
The discussion revolves around the fading of the pink color produced by phenolphthalein during a titration over time Participants explore various chemical processes and factors that may contribute to this phenomenon, including equilibrium shifts, hydrolysis, and the absorption of carbon dioxide
- Exploration into the Physics of Rainbows
The simplest explanation of rainbow physics is based on internal reflections in the near-spherical shape of a raindrop
- Why does a Walrus Blush? | Geophysical Institute
The skin of walruses becomes pallid when it is exposed to cold air or water and changes to pink when exposed to warmer ambient temperatures This color change may indicate that the circulatory output to the skin is altered to control their total body heat loss
- Ice Worms | Geophysical Institute
Ice worms eat airborne pollen grains, fern spores and the red algae that lives in snow and sometimes colors it pink Unable to exist at temperatures much below freezing, ice worms must remain in temperate glaciers
