Chlorophyll Sees Red Among the first facts students learn about the natural world is that plants owe their green color to the pigment chlorophyll. There have actually been a handful of slightly different chlorophyll variants uncovered over the years, and Chen et al.

The Art of Persistence, 2019
A gravitational model for the red shift of absorption lines is given which shows that a receding stellar source is not required. It correctly predicts that the luminosity of a star is inversely proportional to the square of the observed red shift.

Aggregation-induced red shift in N,S-doped chiral carbon dot emissions for moisture sensing
New Journal of Chemistry, 2019Herein, we report aggregation induced red shifted emissions in N,S-doped chiral carbon dots for moisture sensing in common organic solvents and commercial products.

Blooms of microalgal red tides and macroalgae (e.g., green and golden tides caused by Ulva and Sargassum) have caused widespread problems around China in recent years, but there is uncertainty around what triggers these blooms and how they interact. Here,

Acid‐Triggered Aggregation of Carbon Dots Shifted Their Emission to Give Unexpected Deep‐Red Lasing
Advanced Functional Materials, 2023It is challenging to realize ultra‐pH‐responsive fluorescent carbon dots (CDs), especially reversibly adjustable multichromatic emission covering a broad wavelength range including deep‐red lasing.

The Five-Day Retirement Sam Farber lived for 70 years in the Midwest. Once he had tried to retire to Florida, but the retirement lasted for only five days. He got home just in time for the first big snowstorm of the winter. Perhaps it was the lifelong habit of working at his furniture business that brought him back, but even when he returned he was ...

Il Nuovo Cimento B Series 11, 1971
The usual expression for the gravitational red-shiftz is calculated exactly in both the standard and isotropic forms of the Schwarzschild metric. The differing results are found to be meaningless and metric dependent until they are put in terms of quantities directly observable from Earth.

Solar Physics, 1971
The Freundlich red shift of wavelengths in the solar spectrum is discussed. Born's approach on the photon-photon interaction is used in conjunction with Melvin's recalculation of Freundlich's universal constant in order to derive the cross-section for scattering in the solar atmosphere. The new cross-section appears to be 〈σ⊙〉 = 1.58 × 10−18 cm2, which
