Community-driven variations in snow algae color modulate snow albedo reduction. [PDF]
New PhytolSummary Snow algae blooms visibly alter snow color and surface energy balance, yet the biological basis of this variability remains unclear. We investigated how pigment composition and community structure shape the optical properties of snow algae blooms of distinct colors – red, orange, and green – co‐occurring within the same snowfield in Glacier ...

Pigment molecular composition reveals significant information for visual communication
Functional Ecology, Volume 36, Issue 11, Page 2756-2762, November 2022., 2022 Read the free Plain Language Summary for this article on the Journal blog. Abstract Melanins are the most common pigments in vertebrates and, as such, fufill multiple adaptive functions, including honest signalling. This is the case of male pied flycatchers Ficedula hypoleuca, whose dorsal plumage, composed of black and grey feathers pigmented by ...

Blackness and the God of the Oppressed
The Ecumenical Review, Volume 74, Issue 4, Page 576-588, October 2022., 2022 Abstract The state of blackness oscillates between two speculative positions: The first puts forward the irrelevance of race in the modern technological period, a view often coming from those who are colour blind and “optimistic” futurists. The second postulates the need to reaffirm the condition of blackness in a racist and capitalistic production ...

Patients with Retinitis Pigmentosa May Have a Higher Risk of Developing Open‐Angle Glaucoma
Journal of Ophthalmology, Volume 2022, Issue 1, 2022., 2022 Background. Retinitis pigmentosa (RP) is the most common retinal hereditary dystrophy, which can lead to blindness if it progresses. Similarly, open‐angle glaucoma (OAG) is a genetic disorder. The similarities in genetic variants and pathophysiology between RP and OAG have been reported.
