                        Voting for the Public Award of the REFRESH Food Waste Solution Contest is open 1-28 February 2017. Voting is open to all members of the public. The REFRESH Food Waste Solution Contest was launched in 2016 and received over fifty project submissions from across Europe. The aim of the contest is to recognize groundbreaking projects and ideas addressing food waste.

W e find it ironic that so much effort and so many resources are put into the exploration of outer space, at a time when humans are progressively using resources to depletion and when so little is known about the biological diversity of the earth. Why is there all this publicity about ancient life discovered on the planet Mars when there are regions of the Earth where life has yet to be explored? Life at the extremes of environmental conditions are to be found on the Earth. For example, studies of life atgreat depths in the oceans has hardly begun. Recently, an entire new kingdom of deep organisms, the Archaea, has been recognised; although discovered some decades ago, genetic analysis has shown them to be quite unlike any other kind of life (Earle, 1996). We have been concerned to read of proposals for using deep oceans for disposal of global  waste that is inert or rich in metals or even in organic compounds (but not industrial organic compounds). Quite rightly, some prop

To dd Dawson’s field equipment always includes ropes and ascenders, which he and his team use to climb hundreds of feet into the canopies of the world’s largest trees, California’s redwoods. It’s laborious work, but he’ll soon be getting a little help. From drones.
