Driving takes its toll: Emissions database

Date: Apr 15, 2015

Author: David Bradley

Vehicles generate about 28 percent of carbon dioxide emissions from fossil fuels in the USA, a proportion that is rising in many urban areas. Now, researchers have created DARTE (Database of Road Transportation Emissions), a new US wide data inventory to allow more detailed emission studies to be carried out in the context of climate change and other pollution effects.

Carbon calculator: Natural and unnatural methane emissions

Date: Feb 15, 2015

Author: David Bradley

Measurements of the sporadic and perpetual methane emissions from natural gas facilities and processing plants reveals a huge variation in quantities entering the atmosphere across the United States, the implications for the atmospheric carbon burden are important. Moreover, the same pattern or worse might be reflected in data from other regions across the globe.

Journal Highlight: A study of long-term fMRI reproducibility using data-driven analysis methods

Date: Jan 19, 2015

Author: spectroscopyNOW

Long-term fMRI reproducibility has been investigated with a focus on the data analysis methods and the effects of a wavelet-domain Bayesian method and the Gaussian method for smoothing on the long-term reproducibility were assessed.

Epigenetics: Finding the right data signals

Date: Jan 15, 2015

Author:

Epigenetic signals help determine which genes are activated at a given time in a particular cell in the body. Now, researchers in Germany have used a  novel analytical method to enable them to systematically characterize the relevant epigenetic tags and so reveal how the system adapts to the loss of single epigenetic writer and eraser enzymes.
