Periacineta mexicana n. sp. (Ciliophora, Suctoria, Discophryida), Epizoic on Mexican Backswimmers of the Genus Buenoa (Insecta, Hemiptera, Notonectidae) [PDF]

open access: yes, 2010
A new species of suctorian in the genus Periacineta, epibiotic on aquatic bugs (Hemiptera, Heteroptera, Nepomorpha), is described on the basis of morphological characteristics of the cell body, lorica, tentacular placement, and stalk, and its 18S rRNA ...

Multi‐Dielectric Metasurfaces for Ultrabright, Tunable Structural Color and Reconfigurable Optical Filtering with Extraordinarily Large Color Span

open access: yesAdvanced Optical Materials, EarlyView.
Structural color generation is an emerging field for digital display and printing applications. This report presents a novel truncated‐cone design and the first use of GaP sandwiched between two layers of TiO2, demonstrating ultra‐bright, tunable colors with a record color gamut.

Decoding the Mechanism of Action of a Parasite TGFβ Antagonist Inspires the Creation of Cell‐Type‐Specific TGFβ Modulators

open access: yesAdvanced Science, EarlyView.
The mammalian TGFβ interacts with ubiquitously expressed TGFBR1 and TGFBR2, and current TGFβ‐targeting agents are non‐cell‐selective. The cooperative interaction of the modular parasite TGFβ antagonist with multiple host (co‐)receptors empowers the design of TGM chimeras and bispecific antibodies that activate or inhibit TGFβ signaling in a cell ...

Suppressed Auger Heating of Hot Carriers in Cu‐Doped Colloidal Quantum Wells

open access: yesAdvanced Science, EarlyView.
ABSTRACT Auger heating represents a major bottleneck for hot carrier (HC) relaxation in colloidal quantum wells (CQWs), delaying carrier accumulation in band‐edge states and diminishing performance in light‐emitting applications. To address this issue, we introduce copper doping in CdSe CQWs to create midgap states, which efficiently suppresses Auger ...

Genetic Risk and High Burden of Depression and Suicide in the Maya‐Mestizo Population of Yucatán, México

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Major depression and suicide are critical public health concerns, particularly in underrepresented populations with unique genetic and sociocultural contexts. The Maya‐mestizo population presents the highest suicide rates in the country but remains understudied in psychiatric genetics. This study evaluated the association between three genetic
