rssVenom variability: Genetic influences in the pit viper
Date: Oct 16, 2013
Author: Steve Down
The venom proteomes of young jararaca pit vipers that were raised under the same living conditions differ from each other from a very early age, suggesting that the variations are genetically inherited.

Inevitable Nobel: In theory
Date: Oct 15, 2013
Author: David Bradley
The 2013 Nobel Prize for chemistry was awarded jointly to Martin Karplus of the University of Strasbourg, France and Harvard University, Cambridge, Massachusetts, Michael Levitt of Stanford University School of Medicine, Stanford and Arieh Warshel of the University of Southern California, Los Angeles, California, USA for the development of multiscale models for complex chemical systems.

New NMR cancer model: Tracking progress
Date: Oct 15, 2013
Author: David Bradley
A new modelling technique for real-time tracking of metabolic reactions in tumours has been developed by UK researchers. The system based on a simplified computer model of nuclear magnetic resonance spectra could allow oncologists to assess how well their prescribed treatment, whether chemotherapy, radiotherapy or an immunological treatment is progressing without surgical intervention nor the need for regular biopsies.

Rock and a hard place: X-ray tomography digs deep
Date: Oct 15, 2013
Author: David Bradley
X-ray tomography carried out on simulated rock and metal samples could get deep beneath the surface in helping Stanford scientists to understand the way in which iron percolates into the Earth's mantle and how droplets of iron merge under such conditions to form interconnected networks of material.

Laser fluorescence: It's a gas
Date: Oct 15, 2013
Author: David Bradley
Using what they refer to as off-the-shelf, US researchers have developed a laser fluorescence spectroscopic technique to measure how and when nanocrystals adsorb and release hydrogen or other gases. The new investigative approach could be useful in research into lower-cost catalytic converters for vehicle exhausts, the future development of fuel cell technologies and improved gas sensors for industrial and anti-terrorism applications.

Journal Highlight: Near-IR spectroscopy and partial least squares-class modeling for metabolomics fingerprinting discrimination of intervention breakfasts ingested by obese individuals
Date: Oct 14, 2013
Author: spectroscopyNOW
Near-IR spectroscopy has been used in nutritional metabolomics to assess the intake of intervention breakfasts prepared with deep-fried vegetable oils and the resulting urinary patterns were analysed by partial least squares-class modelling.

Journal Highlight: Determination of elemental composition of Lake Baikal sponges by wavelength dispersive X-ray fluorescence spectrometry
Date: Oct 7, 2013
Author: spectroscopyNOW
Wavelength-dispersive X-ray fluorescence spectrometry was used to measure the concentrations of 19 elements in three types of sponges collected from Lake Baikal.

Journal Highlight: Spatial variability in sulphur isotope values of archaeological and modern cod (Gadus morhua)
Date: Oct 7, 2013
Author: spectroscopyNOW
This study presents the first sulphur isotope data of modern and archaeological cod bone collagen for studies of human diet and isotope-based studies of fish trading.

Journal Highlight: Advances in fluorescence diagnosis to track footprints of cancer progression in vivo
Date: Oct 7, 2013
Author: spectroscopyNOW
A broad overview is provided of fluorescence techniques for in vivo cancer diagnosis and therapy monitoring in preclinical models, as well as clinical translation.

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.
