Harlequin Frogs Losing Toxic Defense, Facing Extinction Amid Conservation Challenges

Harlequin frogs, facing severe decline and extinction, are losing their toxic skin defense in captivity due to the absence of natural rainforest bacteria. This vulnerability, compounded by chytrid fungus, challenges reintroduction efforts. Scientists from UC Berkeley and PARC are researching toxin restoration and implementing a 20-year conservation plan.

Airborne Cyanobacterial Toxins Identified in Southwest Florida, Linked to Neurodegenerative Risks

Scientists from Brain Chemistry Labs, in partnership with Calusa Waterkeeper, have identified airborne cyanobacterial neurotoxins, specifically 2,4-DAB, in Southwest Florida. This finding follows previous research linking the toxin to Alzheimer's in beached dolphins and suggests chronic human exposure, posing risks for neurodegenerative diseases like ALS.

Stern warning: one man’s mission to clear the rotting boats poisoning Cornwall’s creeks

Unwanted vessels left to decay release fibreglass shards into the water, harming marine life. Steve Green – with his trusty van Cecil – is determined to clean things upSteve Green, a boat engineer from Cornwall, was pulled over by the police just before Christmas. He was driving a decrepit-looking VW campervan and towing an even more dilapidated yacht up to Truro. He hadn’t broken any laws, but he admits that Cecil the campervan, which runs on donated chip oil from local pubs and has a crane and a winch on the front, “wasn’t quite what VW intended”.Green (and Cecil) are on a mission to rid the beautiful hidden creeks of Cornwall’s Helford and Fal rivers of 166 abandoned fibreglass yachts, which are leaking plastic and toxins into the predominantly marine waters. Marine biologists have likened the thousands of shards of fibreglass they have found embedded in the flesh of sea-creatures in areas with wrecks such as these to asbestos, a substance known to have a noxious effect on humans.Green uses a detachable crane system at the front of his van to move around bags of plastic after they have been weighed. Cecil is upholstered in recycled denim Continue reading...
