Quirks of the human mind and how we process information might explain the uncanny appearances of thylacines.

The Tasmanian tiger is still extinct. Reports of its enduring survival are greatly exaggerated.
Known officially to science as a thylacine, the large marsupial predators, which looked more like wild dogs than tigers and ranged across Tasmania and the Australia mainland, were declared extinct in 1936. But on Feb. 23, Neil Waters, president of the Thylacine Awareness Group of Australia, promised conclusive photographic proof of a surviving thylacine. The four photos, he claimed, showed a family of thylacines, including a juvenile, moving through dense brush. The announcement kicked off a flurry of excitement among wildlife a

Newly published research has revealed a close link between proteins associated with Alzheimer’s disease and age-related sight loss. The findings could open the way to new treatments for patients with deteriorating vision and through this study, the scientists believe they could reduce the need for using animals in future research into blinding conditions.
Amyloid beta (Ab) proteins are the primary driver of Alzheimer’s disease but also begin to collect in the retina as people get older. Donor eyes from patients who suffered from age-related macular degeneration (AMD), the most common cause of blindness amongst adults in the UK, have been shown to contain high levels of Ab in their retinas.
