Land's Retinex theory is used to explain why we perceive the colour of the moon as white. The lightness values of coloured areas are computed and the energy at the particular area (moon) is compared with the surrounding area (space-vacuum).

Clinical Outcomes of Early Phenotype-Desirable Antimicrobial Therapy for Enterobacterales Bacteremia.
JAMA Netw Open
December 2024
School of Pharmacy, University of Maryland, Baltimore.
Importance: Initiating effective therapy early is associated with improved survival among patients hospitalized with gram-negative bloodstream infections; furthermore, providing early phenotype-desirable antimicrobial therapy (PDAT; defined as receipt of a β-lactam antibiotic with the narrowest spectrum of activity to effectively treat the pathogen's phenotype) is crucial for antimicrobial stewardship. However, the timing of targeted therapy among patients hospitalized with gram-negative bloodstream infections is not well understood.
Objective: To compare the clinical outcomes between patients who were hospitalized with Enterobacterales bloodstream infections receiving early vs delayed PDAT.
Nocturnal camouflage through background matching against moonlight.

Camouflage is often considered a daytime phenomenon based on light and shade. Nocturnal camouflage can also occur, but its mechanistic basis remains unclear. Here, we analyze the conditions for background matching (BM) of avian predators against the night sky.

The ability to regulate finger forces is critical for manipulating objects during everyday tasks but is impaired after damage to white matter tracts that transmit motor commands into the spinal cord. This study examines cortico-spinal connectivity required for force control by the digits after neurological injury. We report on a unique case of a stroke survivor who retained the ability to control finger forces at a level comparable to neurologically intact adults despite extensive loss of white matter volume and severely compromised transmission from cortical motor areas onto the final common pathway.

Article Synopsis
- The CMS experiment conducted a search for charge-parity violation in decays using proton-proton collision data from 2018, analyzing around 10 billion events with b hadrons decaying into charm hadrons.
- The flavor of the neutral D meson was determined through the charge of pions in the reconstructed decays, and an asymmetry measurement in the decays was reported, taking into account various uncertainties.
- This research marks the first asymmetry measurement by the CMS in the charm sector and the first to use a fully hadronic final state in such analyses.
Article Synopsis
- A new species of green pitviper named Trimeresurus cyanolabris sp. nov. has been identified in southern and central coastal Vietnam, based on both physical features and DNA analysis.
- This species is characterized by its small size (maximum 638 mm), distinct scale patterns, and unique coloration, including bright yellow eyes and blue shades on its throat and chin.
- The study highlights the phylogenetic separation of this species from similar ones, particularly T. rubeus, and emphasizes the ecological significance of its habitat in tropical forests, which is threatened by deforestation.
