Pot in perfume: Marijuana active component detected

Date: Jan 15, 2017

Author: Steve Down

The principal psychoactive component of marijuana has been found in a commercial perfume by researchers in Austria, although its low concentration does not contravene European regulations.

Prickly pear: Statistical chemicals

Date: Jan 15, 2017

Author: David Bradley

Chemical statistics have been used in the analysis of extracts from two common species found on the Mediterranean, the prickly pear and the peacock's tail seaweed; the chemicals show promise in easing symptoms of Alzheimer's and Parkinson's disease.

Crystallising carbon capture: X-ray study

Date: Jan 15, 2017

Author: David Bradley

A simple, yet reliable, process for trapping carbon dioxide directly from the atmosphere involves the crystallisation of a guanidine sorbent. X-ray diffraction reveals the structural details.

Painting with gumtion: Accelerating art

Date: Jan 15, 2017

Author: David Bradley

J.W.M. Turner used gumtion to make his paintings dynamic. It wasn't simply that he was a dab hand with the brush, he literally used a mixture called gumtion comprising mastic resin with a lead acetate additive to make his oils flow more slicker and smoother across the canvas a spectroscopic study shows.

Moody students? Zinc deficiency could be to blame

Date: Jan 15, 2017

Author: David Bradley

Zinc deficiency has been suggested as one possible risk factor for the onset and progression of mood disorders. A study utilising flame atomic absorption spectrometry (FAAS) has been carried out to assess this hypothesis in adolescent female high school students.

Biomarkers of breast cancer

Date: Jan 12, 2017

Author: Ryan De Vooght-Johnson

The success of cancer treatment hinges on the stage at which the disease is detected, making biomarkers that flag up early signs of the disease an important goal for cancer research. Now a group of scientists from the Czech Republic has found a new set of biomarkers for breast cancer based on the levels of lipids expressed by cancer cells.

Mossy synthesis: Sieboldine

Date: Jan 6, 2017

Author: David Bradley

A new, shorter total synthesis of a complex and intriguing compound, the Lycopodium alkaloid, (+)-sieboldine A, has been carried out by researchers in Japan. Infrared and nuclear magnetic resonance spectroscopy and high-resolution mass spectrometry, as well as optical rotation measurements validated the procedure.
