Man trumps dog: Earlier assumption about BPA exposure confirmed

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

Coating the mouth with BPA-containing food, like soup, does not lead to higher than expected levels of BPA in blood, a new study in Toxicology and Applied Pharmacology shows. The study authors conclude that oral exposure does not create a risk for high exposures of BPA, also known as bisphenol A.

How ionic: Scaffolding is in charge of calcium carbonate crystals

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

Nature packs away carbon in chalk, shells and rocks made by marine organisms that crystallize calcium carbonate. Now, research suggests that the soft, organic scaffolds in which such crystals form guide crystallization by soaking up the calcium like an 'ion sponge,' according to new work in Nature Materials. Understanding the process better may help researchers develop advanced materials for energy and environmental uses, such as for removing carbon dioxide from the atmosphere.

MSL's Radiochemistry Annex: It's getting hot in there

DOE/Environmental Molecular Sciences Laboratory

Researchers from Washington University in St. Louis, Washington State University and Savannah River National Laboratory are among the principal investigators seeking innovative solutions to environmental and energy production challenges in subsurface science. They are also among the scientists who submitted applications to the Special Science Call for Proposals to use EMSL's Radiochemical Annex. Learn more about three research projects using the Annex's resources.

Lengthening the life of high capacity silicon electrodes in rechargeable lithium batteries

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

A new study will help researchers create longer-lasting, higher-capacity lithium rechargeable batteries, which are commonly used in consumer electronics. In a study published in the journal ACS Nano, researchers showed how a coating that makes high capacity silicon electrodes more durable could lead to a replacement for lower-capacity graphite electrodes.

Synthetic fish measures wild ride through dams

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

A synthetic fish is helping existing hydroelectric dams and new, smaller hydro facilities become more fish-friendly. The latest version of the Sensor Fish -- a small tubular device filled with sensors that analyze the physical stresses fish experience -- measures more forces, costs about 80 percent less and can be used in more hydro structures than its predecessor, according to a paper published in the journal Review of Scientific Instruments.

Are my muscular dystrophy drugs working?

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

People with muscular dystrophy could one day assess the effectiveness of their medication with the help of a smartphone-linked device, a new study in mice suggests. The study used a new method to process ultrasound imaging information that could lead to hand-held instruments that provide fast, convenient medical information.

A global natural gas boom alone won't slow climate change

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

A new analysis of global energy use, economics and the climate shows that expanding the current bounty of inexpensive natural gas alone would not slow the growth of global greenhouse gas emissions worldwide, according to a study appearing today in Nature.
