Toward a unified understanding of people’s aversion to nature: biophobia

Frontiers in Ecology and the Environment, EarlyView.
Human–nature relationships are often framed positively, but research rarely addresses biophobia, the aversion to nature. However, negative relationships with nature are likely to become more widespread following societal and environmental changes, with serious implications for public health and conservation efforts.

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Neuroactive venom compounds obtained from Phlogiellus bundokalbo as potential leads for neurodegenerative diseases: insights on their acetylcholinesterase and beta-secretase inhibitory activities in vitro

Journal of Venomous Animals and Toxins including Tropical Diseases, 2021
Background Spider venom is a rich cocktail of neuroactive compounds designed to prey capture and defense against predators that act on neuronal membrane proteins, in particular, acetylcholinesterases (AChE) that regulate synaptic transmission through ...

Diversification of a single ancestral gene into a successful toxin superfamily in highly venomous Australian funnel-web spiders [PDF]

, 2014
Background: Spiders have evolved pharmacologically complex venoms that serve to rapidly subdue prey and deter predators. The major toxic factors in most spider venoms are small, disulfide-rich peptides.
