Frost flowers and sea-salt aerosols over seasonal sea-ice areas in northwestern Greenland during winter–spring

open access: yes, 2016
. Sea salts and halogens in aerosols, frost flowers, and brine play an important role in atmospheric chemistry in polar regions. Simultaneous sampling and observations of frost flowers, brine, and aerosol particles were conducted around Siorapaluk in ...

Acer platanoides 'Schwedleri': 'Schwedleri' Norway Maple

open access: yesEDIS, 2003
This cultivar of Norway Maple has a height of 40 to 50 feet but can grow taller when shaded on the sides. Branches droop toward the ground as the tree grows older forming an oval crown branching to the ground if unpruned.

How is the invasive gorse Ulex europaeus pollinated during winter? A lesson from its native range [PDF]

open access: yes, 2018
Many examples of plant-insect interactions have shown that selection from herbivores can act on flowering and fruiting phenology. In Ulex europaeus (Fabaceae), escaping seed predation resulted in extended, but variable flowering periods, with some plants

High‐Resolution and Real‐Time In Situ Generation of Cellular Spheroids by Laser‐Assisted Bioprinting for Guided Microvascularization

open access: yesAdvanced Functional Materials, EarlyView.
Micro‐injection laser‐assisted bioprinting enables ultrafast and precise patterning of small endothelial cell spheroids by injecting a highly concentrated single‐cell suspension into GelMA/ColMA hydrogels. In co‐culture with fibroblasts, controlled pre‐vasculogenic network formation is obtained at microscale resolution.

Frost and flowers: Predicting the effects of climate change on spring frost damage using a large pollen count dataset [PDF]

open access: yes, 2010
Background/Question/Methods Climate change is resulting in warmer average temperatures in much of North America, leading to earlier flowering dates for most tree genera.

Parallel 3D Bioprinting on SLIPS‐Microarrays

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces the first truly parallel 3D bioprinting method, enabling both the simultaneous fabrication of hundreds of cell laden hydrogel 3D structures and their HTS in individual liquid compartments. By integrating Digital Light Processing (DLP) stereolithography with functional micropatterns, the platform decouples printing time from array ...

Effects of season of fire on bee‐flower interaction diversity in a fire‐maintained pine savanna

open access: yesEcology and Evolution, 2023
Whereas the Coastal Plain of the southeastern United States historically experienced fire primarily during the mid‐summer lightning season, managers today typically apply prescribed fire during the late winter or early spring months.

Growing azaleas and rhododendrons (2012) [PDF]

open access: yes, 2012
Azaleas and rhododendrons are shrubs for all seasons. In winter some stand out with large evergreen leaves. In spring the flowers are showy; throughout the summer and fall the leaves add a pleasing, deep green color to the garden.

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

open access: yesAdvanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.
