'Olivia R. Cooper' 'Arianna S. Long' 'Maximilien Franco' 'Sinclaire M. Manning'] JWST has revealed a ubiquitous population of "little red dots" (LRDs) at z >∼ 4, selected via their red rest-frame optical emission and compact morphologies. They are thought to be reddened by dust, whether in tori of active galactic…

We argue that a high pressure phase transition of relativistic matter to a state with negative energy density, which leads to the formation of horizonless, globally unitary black hole mimickers, can also give rise to the appearance of "little red dots". The energy source for the dots is the release of latent energy…

Cold, substellar objects such as brown dwarfs have long been recognized as contaminants in colorselected samples of active galactic nuclei (AGNs). In particular, their near- to mid-infrared colors (1–5 µm) can closely resemble the V-shaped (fλ) spectra of highly-reddened accreting supermassive black holes ("little red…

Recent observations by the James Webb Space Telescope (JWST) have revealed a previously hidden population of extremely bright and compact objects between redshifts of z ∼ 4 and z ∼ 10. Given their extreme red colouring in the observed frame these galaxies have been dubbed Little Red Dots (LRDs). The aim of this project…

Quantum dots (QDs), and carbon quantum dots (CDs) in particular, have received significant attention for their special characteristics. These particles, on the scale of several nanometers, are often produced using simple and green methods, with naturally occurring organic precursors. In addition to facile production…

Red dot basal cell carcinoma is a unique variant of basal cell carcinoma. Including the three patients described in this report, red dot basal cell carcinoma has only been described in seven individuals. This paper describes the features of two males and one female with red dot basal cell carcinoma and reviews the…

Carbon dots (C-dots) represent an emerging class of nontoxic nanoemitters that show excitation wavelength-dependent photoluminescence (PL) with high quantum yield (QY) and minimal photobleaching. The vast majority of studies focus on C-dots that exhibit the strongest PL emissions in the blue/green region of the…

Infantile hemangioma is a common benign vascular proliferation seen in the pediatric age group. Dermoscopy of hemangioma shows lacunae of variable sizes and dilated vessels against a red to reddish blue background . We report the dermoscopic evaluation of regression of infantile hemangioma on topical timolol. A 3-month…

Unilateral linear capillaritis (ULC) is a rare variant of pigmented purpuric dermatosis (PPD). It is characterized by unilateral, progressive, linear eruption of purpuric patches or macules. It is a benign condition and often resolves spontaneously. To the best of our knowledge, ULC dermoscopic features have only been…

Background Little is known about the dermoscopic evaluation of cutaneous adverse drug reactions (CADRs). Objectives To evaluate the dermoscopic patterns of CADRs and identify those associated with severe cutaneous adverse reactions to drugs (SCARDs). Patients and Methods Patients included in this study from May 2015 to…

Nesidiocoris tenuis is an important zoophytophagous mirid bug used as a biological control agent in agriculture, and breeding efforts based on genomic information aim to increase its utility. Visible eye-color mutants are useful genetic markers because they are easily distinguishable and are therefore widely used in…

Recent studies examine the behavioral capacities of rats and mice with and without visual input, and the neuronal mechanisms underlying such capacities. These animals are assumed to be functionally blind under red light, perhaps originating in the fact that they are dichromats who possess ultraviolet and green but not…

The Atlantic Canary (Serinus canaria) is the most common caged bird with extensive carotenoid plumage coloration. Domestic strains of canaries have been bred for a range of colors and patterns, making them a valuable model for studies of the genetic bases for feather pigmentation. However, no detailed account has been…
