Showing results for "Mars" in Biological Sciences

It seems likely that scientists will someday discover how life can emerge on habitable planets like the early Earth and Mars. In Origin of Life: What Everyone Needs to Know, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections.

Beyond images of emaciated polar bears and drought-cracked lakes, there remains a major part of climate change's impact that the media has neglected: how our health will suffer from higher temperatures and extreme weather. From spiraling rates of asthma and allergies and spikes in heatstroke-related deaths to swarms of invasive insects carrying diseases like dengue or West Nile and increases in heart and lung disease and cancer, the effect of rising temperatures on human health will be far-reaching, and is more imminent than we think.

Hersenen fossiliseren niet waardoor het lastig is om de evolutie van het brein te onderzoeken. Maar door de hersenen van verschillende nog levende dieren te vergelijken, is het mogelijk te begrijpen welke uitdagingen de voorouders van die dieren hadden en hoe hun gedrag en hersenen zich daaraan hebben aangepast. Neurowetenschapper Rogier Mars onderzoekt in zijn hoorcollege de ontwikkeling en werking van het brein aan de hand van het eet- en leefgedrag van dieren als de zakpijp, de eekhoorn en de wolf, diverse primaten, zoals de lemuur en chimpansee, en natuurlijk de mens zelf.
