Islet Amyloid Polypeptide Modelled to Simulate Diabetes Co‐Oligomerized with β‐Amyloid 1‐42 Reproducing the Pathological Cascade of Alzheimer's Disease in Human Cerebral Organoids

Advanced Science, EarlyView.
Human islet amyloid polypeptide (hIAPP) was used to mimic T2DM, and Aβ42‐hIAPP co‐oligomers were delivered into the human mature cerebral organoids (COs), which reproduce typical AD pathology and significant neuronal death more closely resembling that of AD patients.

The return to water in ancestral Xenopus was accompanied by a novel mechanism for producing and shaping vocal signals

eLife, 2019
Listeners locate potential mates using species-specific vocal signals. As tetrapods transitioned from water to land, lungs replaced gills, allowing expiration to drive sound production. Some frogs then returned to water.

Developmental changes and novelties in ceratophryid frogs [PDF]

, 2016
The Neotropical frog genera Ceratophrys, Chacophrys and Lepidobatrachus form the monophyletic family Ceratophryidae. Although in- and out-group relationships are not fully resolved, the monophyly of the three genera is well supported by both ...

Hydrogen‐Bonding Networks Enabled by Trace Water for Morphological Design in Ternary Organic Solar Cells

Advanced Science, EarlyView.
Trace water transforms from an impurity to a design handle for ternary organic solar cells. During solvent evaporation, minimal amounts organize transient hydrogen‐bonding networks that steer component migration and set the morphology. The mechanism enables reproducible morphology locking and identifies a practical co‐solvent threshold near H2O:CF = 0 ...

Sexual dimorphism, fresh water dispersal range, and prey items of Marine toads (Rhinella marina) in Lennox Head, Australia [PDF]

, 2012
The invasive cane or marine toad (Rhinella marina) has spread across much of Australia since its initial introduction in 1935. Naturally found in Central and South America, R.

Selectivity Filter Dynamics Define Ion Conductance and Selectivity Differences in CNG and HCN Channels

Advanced Science, EarlyView.
Cyclic nucleotide‐gated (CNG) and hyperpolarization‐activated cyclic nucleotide‐gated (HCN) channels share substantial sequence and structural similarity but differ markedly in ion conductance and K+ selectivity. Microsecond‐scale atomistic MD simulations qualitatively reproduced the conductance differences observed in single‐channel recordings and ...

Habitat heterogeneity and anuran community of an agroecosystem in the Pantanal of Brazil

Phyllomedusa: Journal of Herpetology, 2014
The Pantanal of central Brazil has experienced considerable modifications as a result of growing land use. The association between anuran assemblage and the local habitat structure of an agroecosystem in central Brazil at the Pantanal is described. It is

Like a Fish out of Water: Temporary Habitat Switching Detected in Aquatic Tadpoles Resting Above the Water's Surface

Ecology and Evolution
Amphibian tadpoles are typically aquatic and constrained to freshwater throughout development. These circumstances change at metamorphosis, whereupon individuals may complete a partial or full habitat shift towards terrestriality and gain the capacity to

Crocker Range National Park, Sabah, as a refuge for Borneo’s montane herpetofauna [PDF]

, 2006
Crocker Range National Park in Sabah (East Malaysia), northern Borneo, is an exceptional area for herpetological diversity. Inventories of the Park are incomplete, but show high diversity, as well as regional endemicity shared with the adjacent and more ...
