The Science Basement

Why study microbes in polluted environments?

It is estimated that every 2.6 seconds, a new chemical substance is isolated or synthesized, adding to nearly 200 million identified chemical substances in the world. While many of these are essential for society and not harmful to the environment, one effect of this proliferation of chemicals in our everyday lives has been the increase of polluted environments with multiple contaminants.

Poseidonia, greeks, non-greeks & religious cults: let’s talk archaeology!

Traditional historical and archaeological researchers have long thought that Ancient Greek colonies were ethnically and culturally exclusively Greek. In fact, they figured that Greek culture dominated over that of bordering nations and was immune to outside influences like neighboring non-Greek populations. But was that actually the case? The cult of goddess Hera in the Greek colony of Poseidonia, Southern Italy, offers a different perspective. Surprisingly, even religion, which is typically conservative as it defines its worshippers, showed signs of outside influence. This month Gianluca will share how he interprets offerings to the goddess Hera and excavation reports to piece together the potential dynamics of ancient Greek colonization, and to understand the role played by non-Greek populations in the life and development of “Greek” colonies.

The Earth’s Radiation Belts and their Space Weather Effects

Near-Earth space is full of high-energy particles that are trapped in the Earth’s magnetic field. These particles form the radiation belts and create an extremely hazardous environment that satellites must pass through. Understanding how radiation belt particles move, how they become energised and how these particles can be lost from the radiation belts is essential to protect satellites orbiting the Earth. In this talk, Harriet George will present an overview of the Earth’s radiation belts and its dangers.
