The thin edge of the wedge: extremely high extinction risk in wedgefishes and giant guitarfishes
bioRxiv, 2019 The process of understanding the rapid global decline of sawfishes (Pristidae) has revealed great concern for their relatives, the wedgefishes (Rhinidae) and giant guitarfishes (Glaucostegidae), not least because all three families are targeted for their

Pleistocene preserve: a population growth problem of mammoth proportions
Evolution: Education and Outreach, 2019 A number of processes that involve large numbers are critical to civic scientific literacy, including many biological topics. Understanding the basic causes of such large-scale processes, such as population growth, speciation, and extinction, are key to ...

A Vertically‐Stacked Optoelectronic Sensor for Localized Hemodynamics Monitoring
Advanced Functional Materials, EarlyView.This work introduces a hemodynamics monitoring sensor that features vertically stacked microLEDs and a heterogeneously integrated photodetector. The vertically stacked microLEDs enable localized measurements, and by designing the interoptode distance according to the depth of the target region, this vertically stacked optoelectronic sensor is ...

The rise of the ruling reptiles and ecosystem recovery from the Permo-Triassic mass extinction
Proceedings of the Royal Society B: Biological Sciences, 2018 One of the key faunal transitions in Earth history occurred after the Permo-Triassic mass extinction (ca 252.2 Ma), when the previously obscure archosauromorphs (which include crocodylians, dinosaurs and birds) become the dominant terrestrial vertebrates.

Biologically based neural circuit modelling for the study of fear learning and extinction [PDF]
npj Science of Learning, 2016 AbstractThe neuronal systems that promote protective defensive behaviours have been studied extensively using Pavlovian conditioning. In this paradigm, an initially neutral-conditioned stimulus is paired with an aversive unconditioned stimulus leading the subjects to display behavioural signs of fear.

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose
Advanced Materials, EarlyView.Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Ecological Finitude as Ontological Finitude: Radical Hope in the Anthropocene [PDF]
, 2018 The proposal that the earth has entered a new epoch called “the Anthropocene” has touched a nerve . One unsettling part of having our ecological finitude thrust upon us with the term “Anthropocene” is that, as Nietzsche said of the death of God, we ...
