"Sight"-restoring bionic eye proceeds along the path to human trials


There may be new hope for people with certain types of blindness, as an experimental sight-restoring device has been deemed safe for implantation. It still has to be tested on humans, though, and it will likely provide a fairly rudimentary form of vision.

Known as the Phoenix99 Bionic Eye, the prosthesis is currently being developed by scientists at Australia's University of Sydney and University of New South Wales. It's intended for use on patients with blindness caused by degenerative conditions such as retinitis pigmentosa, in which the retina is compromised but the optic nerve remains intact.

Plant extract could treat malaria when conventional drugs fail


For many years now, people in parts of Africa have used a tea made from the crushed leaves of a certain plant to treat malaria. Scientists recently identified the active ingredient, and believe that it could be used in alternative pharmaceutical treatments for the disease.

The plant in question is a member of the buttercup family – its scientific name is Ranunculus multifidus. When it gets injured and the insides of its cells get exposed to the air, it produces a compound known as anemonin. It is this chemical that was found to be effective against malaria.
