Recent Insights Into Alzheimer's Disease: Advances in Pathophysiology and Therapeutic Strategies
Brain Health, EarlyView.ABSTRACT Alzheimer's disease (AD) is a complex neurodegenerative disorder driven by interplay among amyloid‐β (Aβ) plaques, tau neurofibrillary tangles, inflammation and comorbid pathologies. Recent advances in biomarkers and therapeutic approvals have reshaped our understanding of its pathophysiology and treatment landscape.

Biological Reviews, EarlyView.ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

Quantifying the dynamic wing morphing of hovering hummingbird [PDF]
Royal Society Open Science, 2017 Animal wings are lightweight and flexible; hence, during flapping flight their shapes change. It has been known that such dynamic wing morphing reduces aerodynamic cost in insects, but the consequences in vertebrate flyers, particularly birds, are not ...

Sentience in cephalopod molluscs: an updated assessment
Biological Reviews, EarlyView.ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

Hovering hummingbird wing aerodynamics during the annual cycle. I. Complete wing [PDF]
Royal Society Open Science, 2017 The diverse hummingbird family (Trochilidae) has unique adaptations for nectarivory, among which is the ability to sustain hover-feeding. As hummingbirds mainly feed while hovering, it is crucial to maintain this ability throughout the annual cycle ...

Biological Reviews, EarlyView.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales
Nordic Journal of Botany, EarlyView.Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...
