Ancient Rain: Historic monsoons could help us respond to climate change

...chemistry of tiny (about the size of a sand grain) ocean-dwelling organisms called foraminifera. These organisms build their shells from calcium carbonate, soaking up the chemistry of the seawater surrounding them as they do this. The chemistry of the seawater that they lock into their shells can record the temperature of the seawater that they grew in and how fresh or...

...is of enormous importance in everyday life: almost everything that exists, and all that we see, make and eat is composed of molecules. The unravelling of molecular structure is a key activity of chemists. In these three video tracks, Dr Mike Bullivant looks briefly at three of the spectroscopic techniques that are used to determine the structure of chemical compounds -

Safer battery could spark investment in renewables

...chemistry student at Harvard, Michael Marshak, now assistant professor of chemistry at the University of Colorado, Boulder, and colleagues report in Science journal that, instead of costly and difficult-to-handle metals, they have tested naturally-occurring, carbon-based molecules called quinines for the negative electrolyte component of the battery. They had started...
