An atypical gross form of climatic droplet keratopathy (CDK) occurring in the cornea of 24 eyes of 17 leprosy patients is described. The CDKs were situated in the lower outer quadrant of the cornea and were not associated with trauma, scars or vascularization. All patients, except one, belonged to the lepromatous group. Fifteen of the 24 eyes with this form of CDK had impaired corneal sensation. We suggest that this form of CDK is a distinctive condition found among lepromatous leprosy patients with possible infection and involvement of the corneal nerves.

Plastid-localized plastoglobules (PGs) are monolayer lipid droplets typically associated with the outer envelope of thylakoid membranes in chloroplasts. The size and number of PGs can vary significantly in response to different environmental stimuli. Since the early 21st century, a variety of proteins attached to the surface of PGs have been identified and experimentally characterized using advanced biotechnological techniques, revealing their biological functions.

In both nature and industry, aerosol droplets contain complex mixtures of solutes, which in many cases include multiple inorganic components. Understanding the drying kinetics of these droplets and the impact on resultant particle morphology is essential for a variety of applications including improving inhalable drugs, mitigating disease transmission, and developing more accurate climate models. However, the previous literature has only focused on the relationship between drying kinetics and particle morphology for aerosol droplets containing a single nonvolatile component.

Ice accretion caused by freezing rain or snowstorms is a common phenomenon in cold climates that seriously threatens the safety and reliability of telecommunication lines and other overhead networks. Various anti-icing strategies have been demonstrated through surface engineering to delay ice formation. However, existing anti-icing surfaces still encounter several challenges; for example, surfaces are prone to ice-pinning formation due to the impact of supercooled droplets, which leads to a loss of anti-icing effectiveness.

The caribou ( sspp.) is a keystone wildlife species in northern ecosystems that plays a central role in the culture, spirituality and food security of Indigenous People. The Arctic is currently experiencing an unprecedented rate of climate change, including warming temperatures and altered patterns of precipitation.
