Overcoming depression, fast


IN THE climate change discourse, the role of trees and forests has largely been seen as carbon stocks and carbon sinks. Now scientists are beginning to study a more fundamenta­l correlatio­n—the direct effects that trees and forests have on climate through rainfall and cooling. Trees help retain water on the ground and produce cooling moisture, which, in turn, have a positive impact on food security and climate change adaptation. Scientists say the direct relevance of trees in protecting and intensifyi­ng the hydrologic cycle, associated cooling and the sharing of atmospheri­c moisture is beyond reasonable doubt. Scientists believe that emerging research must deeply explore the widening impact of trees on climate.

six of us suffer from depression at some point in our lifetime. In an attempt to find faster-acting antidepres­sant medication­s, researcher­s have found that inhibiting an enzyme called Glyoxalase 1 (GLO1) relieves depression faster than existing medicines. When they tested their research on mice, they found that those inhibiting the GLO1 enzyme reduced depression-like symptoms in five days, whereas it took 14 days for Prozac to have the same effect. The medicines are yet to be tested on humans.
