Interactions of Interaural Time and Level Differences in Spatial Hearing with Cochlear Implants
Advanced Science, EarlyView.Differences in timing (ΔT) are weighted heavily compared to differences in loudness (ΔL) in binaural hearing with cochlear implants. Abstract Normally hearing humans can localize sound sources quite accurately, with minimum audible angles as small as 1°. To achieve this, these auditory pathways combine information from multiple acoustic cues, including

Parallel evolution of KCNQ4 in echolocating bats. [PDF]
PLoS ONE, 2011 High-frequency hearing is required for echolocating bats to locate, range and identify objects, yet little is known about its molecular basis. The discovery of a high-frequency hearing-related gene, KCNQ4, provides an opportunity to address this question.

Long-term and persistent vocal plasticity in adult bats. [PDF]
, 2019 Bats exhibit a diverse and complex vocabulary of social communication calls some of which are believed to be learned during development. This ability to produce learned, species-specific vocalizations - a rare trait in the animal kingdom - requires a ...

Advanced Science, EarlyView.Particulate matter ≤2.5 µm (PM2.5) elevates risks of neurological and chronic metabolic diseases, but the underlying mechanisms linking PM2.5‐induced central nervous system (CNS) injury to metabolic dysfunction remain unclear. Hypothalamic pro‐opiomelanocortin‐expressing (POMC+) neurons regulate systemic metabolic homeostasis, and tripartite motif ...

Recurrent evolution of extreme longevity in bats
Biology Letters, 2019 Bats live longer than similar-sized mammals, but the number of lineages that have independently evolved extreme longevity has not previously been determined.

Advanced Science, EarlyView.Exclusive breastfeeding establishes a thermogenic memory in brown adipose tissue by activating the HIF1AN/AMPK/α‐ketoglutarate axis via milk‐derived extracellular vesicles enriched in miR‐125a‐5p. This programming preserves metabolic health, while αKG supplementation restores BAT function under mixed feeding, offering strategies to mitigate the ...

Florida's Bats: Velvety Free-Tailed Bat
EDIS, 2016 The velvety free-tailed bat is found nowhere in the United States but extreme south Florida. These bats emerge from their roosts earlier than most other bats, often shortly before sunset. This 2-page fact sheet explains how to differentiate velvety free-

Immune System Modulation and Viral Persistence in Bats: Understanding Viral Spillover
Viruses, 2019 Bats harbor a myriad of viruses and some of these viruses may have spilled over to other species including humans. Spillover events are rare and several factors must align to create the “perfect storm” that would ultimately lead to a spillover.

Advanced Science, EarlyView.Aged HSF1 muscle‐specific knockout mice show deteriorated muscle atrophy and metabolic dysfunction, while active HSF1 overexpression improves muscle function via activating SIRT3 to deacetylate both PGC1α1 and PGC1α4, which boosts mitochondrial function and muscle hypertrophy in a fiber‐type specific manner, and induces FNDC5/Irisin for tissue ...
