Researchers study the mechanisms of skin aging
The aging process is most apparent on the skin. In the newly opened SKINMAGINE (Multimodal Imaging of Aging and Senescence of the Skin) Christian Doppler Laboratory, dermatologists from MedUni Vienna have joined forces with biotechnologists from the University of Natural Resources and Applied Life Sciences Vienna and chemists from Vienna University of Technology, as well as the company Chanel, to study the interaction of metabolism, cellular communication and cellular quality control in skin aging accelerated by environmental stress.
Skin aging does not happen in isolation but in interaction with the environment and changing processes in the body as a whole. It is accelerated by the urban exposome , the combined impact of factors such as environmental pollution and sunlight. Normal skin aging and skin aging accelerated by the urban lifestyle affect lipid, protein and glucose metabolism, the capacity for regeneration and communicatio
When not busy trying to murder humans in
The Matrix, the AI program known as Agent Smith took time to pontificate on our nature as a species. You canât really consider us mammals, he reckoned, because mammals form an equilibrium with their environment. By contrast, humans move to an area and multiply âuntil every natural resource is consumed,â making us more like a kind of virus. âHuman beings are a disease,â he concluded, âa cancer of this planet. You are a plague.â
I think, though, that it would be more accurate to describe humanity as a kind of biofilm, a bacterium or fungus thatâs grown as a blanket across the planet, hoovering up its resources. We plop down great cities of concrete and connect them with vast networks of highways. We level forests for timber to build homes. We turn natural materials like sand into cement and glass, and oil into asphalt, and iron into steel. In this reengineering of Earth, weâve imperiled countless
Neglected or overlooked local food crops could well be making a comeback into markets in Africa thanks to the work of a consortium of scientists.
‘Orphan’ crops, which include a range of neglected or overlooked plants producing fruits, vegetables, legumes, grains and roots, are often very nutritious and can suit current agricultural systems. They also have extensive, although reducing, genetic diversity. As their name suggests, orphan crops have mostly rarely been researched. However, scientists, governments and agricultural development agencies have been re-thinking the importance of orphan crops because of the risk of growing only nutritionally limited and resource-intensive crops, as most of the world does now.
