Laser‐Microscribed Glass Enables Surface‐Microfluidics‐Facilitated, Affordable, Rapid Cancer Diagnosis

open access: yesAdvanced Functional Materials, Volume 36, Issue 24, 23 March 2026.
A transparent, laser‐microscribed glass platform enables cancer diagnosis within 1 h—much faster than histology, which takes days, and free from the chemical or contrast risks of MRI or CT scans. The antibody‐functionalized rough glass surface captures viable cancer cells directly from suspension, allowing instant optical readout and offering a rapid ...

Roughing It: Topography and Surface Chemistry of Hierarchical Diamond Coatings Modulate Protein and Cellular Interactions

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 10, 13 March 2026.
Hierarchically structured diamond coatings are synthesized using a bottom‐up approach to control surface topography across multiple length scales. This study demonstrates how topography and chemistry jointly modulate protein adsorption and cellular behavior, revealing design principles for next‐generation biomaterials that enhance early cell attachment,

Survival and Biofilm Formation of Pseudomonas Putida Under Glucose Starvation on Model Sand Surfaces

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 1, January–February 2026.
P. putida retains viability in sand columns for an extended period of at least 80 days under carbon‐deprivation P. putida increased protein production on their surfaces, enhancing biofilm integrity and adhesion to sand surfaces compared to fed biofilms.

CARACTERISTICAS ESTRATIGRAFICAS Y MORFODINAMICAS DE LA FRANJA LITORAL CARIBE COLOMBIANA(SECTOR BARRANQUILLA (BOCAS DE CENIZA) - FLECHA DE GALERAZAMBA)

open access: yesBulletin of Marine and Coastal Research, 2016
The geologic (stratigraphic) and morphodynamic characteristics throughout 76 km of the coastal profile of the Colombian Caribbean, including those between Barranquilla (Bocas de Ceniza) and the spit of Galerazamba are described. The sections of the coast that have been affected by erosive events and those with sedimentary accretion are described.

Parasites Are Paramount: Vertical Trophic Positions of Parasitic Catfishes in a Tropical River Food Web

open access: yesEcology of Freshwater Fish, Volume 34, Issue 4, October 2025.
ABSTRACT The Neotropical catfish family Trichomycteridae contains parasitic fishes that include scale and mucus feeders (subfamily Stegophilinae) and blood feeders (i.e., ‘candirus’, subfamily Vandelliinae). The influence of parasitic catfishes on food web dynamics is unknown.
