Inborn error testing: Immunodeficiency disease added to newborn screening program

Date: Nov 1, 2013

Author: Steve Down

Italian researchers have succeeded in incorporating a test for the inborn error ADA-SCID into a routine newborn screening program for inherited metabolic disorders, saving much time providing earlier diagnosis of this fatal disease.

Self-powered ionisation: Kelvin spray ion source

Date: Oct 17, 2013

Author: Steve Down

A new type of dual-spray ion source for soft ionisation based on the Kelvin water dropper produces positive and negative ions simultaneously and does not require a power supply.

Moondust mystery: LADEE mission into the lunar atmosphere

Date: Oct 2, 2013

Author: Steve Down

NASA has launched a mission to the Moon to study the very thin atmosphere that exists there as well as the composition of moondust which might be responsible for the atmospheric glow reported by the Apollo astronauts.

Watching paint dry: Proton transfer mass spectrometry for indoor studies

Date: Sep 16, 2013

Author: Steve Down

The value of proton transfer reaction mass spectrometry for following the emission of volatile organic compounds in indoor spaces has been demonstrated by several examples, including laser printer discharges and paint drying.

Journal Highlight: Condensed-phase laser ionization time-of-flight mass spectrometry of highly energetic nitro-aromatic compounds

Date: Sep 9, 2013

Author: spectroscopyNOW

Explosive nitro-aromatic compounds have been studied by laser ionization TOFMS to understand their mass spectra when directly ionized in the condensed phase in the absence of matrix.

The decline in bees: Are pesticide surfactants to blame?

Date: Sep 2, 2013

Author: Steve Down

High levels of the trisiloxane components of pesticides have been measured in beeswax and pollen from beehives, suggesting that their effects on the health of bees should be examined in detail due to the global decline in honey bees.

Signs of ageing: Metabolite linked to rate of ageing

Date: Aug 15, 2013

Author: Steve Down

A panel of human metabolites that correlate with age has been identified from a study on thousands of twins, leading to the possibility of a blood test that can predict which people are likely to age rapidly.

Surgical mass spec: Intelligent knife finds tumour margins in real time

Date: Aug 1, 2013

Author: Steve Down

A new surgical device known as the iKnife will help surgeons to remove every part of a tumour by analysing the smoke emitted during electrosurgery in real time using an online mass spectrometer.
