Heavy metals in your hibiscus: Infusion refusal

Date: May 15, 2013

Author: David Bradley

Inductively coupled plasma optical emission spectrometry (ICP-OES) and flame atomic absorption spectroscopy (FAAS) have been used to determine concentrations of metals in digests and infusions of Hibiscus sabdariffa (petals), Rosa canina (receptacles), Ginkgo biloba (leaves), Cymbopogon citratus (leaves), Aloe vera (leaves) and Panax ginseng (roots).

Shrinking the proton: Laser scan

Date: Feb 15, 2013

Author: David Bradley

An international research team has confirmed the surprisingly small radius of the proton using laser spectroscopy on muonic hydrogen. The new results fuel the debate as to whether the discrepancies observed can be explained by standard physics, for example an incomplete understanding of the systematic errors that are inherent to all measurements, or whether they are due to new physics, or a higher complexity than previously assumed for the structure of the proton.
