Groundbreaking research led by the U.S. Department of Energy Joint Genome Institute (DOE JGI) demonstrates for the first time that the signatures of the genes alone in terrestrial and aquatic samples can accurately diagnose the health of the sampled environments. This study, published in the April 22nd edition of the journal Science positions large-scale genome sequencing to accelerate advances in environmental sciences akin to the contributions DNA sequencing has made to biomedical sciences.
"These DNA sequence fingerprints can be used to provide highly accurate assessments of the vitality of extremely diverse environments," said Dr. Raymond L. Orbach, Director of the DOE Office of Science, which supported the research. "These fingerprints can be used to reveal environments under stress as well as signal progress in remediating contaminated environments. This may well develop environmental ecology into a fully quantitative science."
Dubbed Environmental Genomic Tags, or EGTs, these indicators capture a DNA profile of a particular niche and reflect the presence and levels of nutrients, pollutants, and other environmental features.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
