Free Waters Corporation Webinar:Dried Blood Spot Bioanalysis: Addressing the Sensitivity Challenge
Dried blood spots (DBS) have been used for many years in neonatal testing using either a heel or finger prick onto a piece of paper which is then dried and shipped for analysis. This approach has now been applied to the field of bioanalysis in preclinical, toxicokinetic, and clinical studies. DBS has several benefits.

Magnetic resonance (MR) spectroscopy may in the future be able both to pinpoint the precise location of prostate cancer and to determine the tumour's aggressiveness, information that could help guide treatment planning. In Science Translational Medicine (doi: 10.1126/scitranslmed.3000513), Massachusetts General Hospital (MGH) researchers report how spectroscopic analysis of the biochemical makeup of prostate glands accurately identified the location of tissue confirmed to be malignant by conventional pathology.

Children as young as five months old will follow the gaze of an adult towards an object and engage in joint attention, according to research at Birkbeck, University of London, funded by the Wellcome Trust and the Medical Research Council. The findings, published in Biology Letters (doi: 10.1098/rsbl.2009.1069), suggest that the human brain develops this important social skill surprisingly early in infancy.

Researchers at the University of St Andrews have developed a powerful technique that could allow earlier cancer detection. In a joint venture between the Schools of Physics & Astronomy and the Bute Medical School, the St Andrews researchers have advanced new technology that relies on Raman spectroscopy.
The European Commission has cleared, under the EU Merger Regulation, the proposed acquisition of Varian Inc. by Agilent Technologies Inc., both US companies, by way of purchase of shares. The decision is conditional upon the divestment of Agilent's entire micro/portable gas chromatography instrument business and Varian's entire laboratory gas chromatography, triple quadrupole gas chromatography-mass spectrometry and inductively coupled plasma-mass spectrometry instrument businesses. In view of the remedies proposed, the Commission has concluded that the operation would not significantly impede effective competition in the European Economic Area (EEA) or any substantial part of it.
The winners of the 2010 Pittcon Awards include a good number of spectroscopists, and names that will be familiar to readers.
Trace gas spectroscopic detection has drawn much interest in recent years, as it both allows a better understanding of the molecular spectra of weak overtone transitions and in situ non-intrusive sensing of compounds at low concentration. However, recording a broadband spectrum within a very short measurement time and with high sensitivity remains a challenge. Now, scientists at the Max Planck Institute of Quantum Optics have recorded ultrasensitive absorption broadband spectra within tens of microseconds by combining cavity enhancement and frequency comb spectroscopy.
