Five Environmental Consequences of Australia’s Fires

Environmental consequences of nuclear war

groups made valuable contributions to elaborating the consequences of nuclear warfare.1 Paul Crutzen and John Birks proposed that massive fires and smoke emissions in the lower atmosphere after a global nuclear exchange would create severe short-term environmental aftereffects. Extending their work, two of us (Toon and Turco) and colleagues discovered “nuclear winter,” which posited that worldw...

Neural consequences of environmental enrichment.

Neuronal plasticity is a central theme of modern neurobiology, from cellular and molecular mechanisms of synapse formation in Drosophila to behavioural recovery from strokes in elderly humans. Although the methods used to measure plastic responses differ, the stimuli required to elicit plasticity are thought to be activity-dependent. In this article, we focus on the neuronal changes that occur ...

Sorting Out the Environmental Consequences

Biometeorological consequences of environmental controls: overview.

We have studied the genetic alterations acquired during selection of a cloned human leukaemic cell line (CEM/VP-1) that is 15-fold more resistant to the anticancer topoisomerase Il-inhibitor etoposide than parental CCRF-CEM cells. CEM/VP-1 cells exhibit an 'atypical MDR' phenotype: cross resistance to other topo II inhibitors (but not Vinca alkaloids) and expression of a drug-resistant topo II ...

Overview: biological consequences of environmental control.

A retrospective analysis of 108 cases of primary germ cell tumours of testis seen over a 6 year period at Institute Rotary Cancer Hospital of All India Institute of Medical Sciences, New Delhi is presented. There were 45 (42%) cases of seminoma and 63 (48%) of non-seminomatous germ cell tumours (NSGCT). The median age at presentation was 35 and 30 years respectively. Almost half (56) patients p...
