In an effort to create a power source for future implantable technologies, a team of researchers developed an electric eel-inspired device that produced 110 volts from gels filled with water, called hydrogels. Their results show potential for a soft power source to draw on a biological system's chemical energy. Anirvan Guha will present the research during the 62nd Biophysical Society Annual Meeting, Feb. 17-21.

A research team led by the University of Georgia has discovered that manipulation of the same gene in poplar trees and switchgrass produced plants that grow better and are more efficiently converted to biofuels.
Today, the dome closes on the previous science chapters of the 4-meter Mayall Telescope in Arizona so that it can prepare for its new role in creating the largest 3-D map of the universe. This map could help to solve the mystery of dark energy, which is driving the accelerating expansion of the universe.
For the first time, scientists demonstrated a long-theorized nuclear effect called nuclear excitation by electron capture. This advance tests theoretical models that describe how nuclear and atomic realms interact and may also provide new insights into how star elements are created.
Searching for a power outlet may soon become a thing of the past. Instead, devices will receive electricity from a small metallic tab that, when attached to the body, is capable of generating electricity from bending a finger and other simple movements. That's the idea behind a collaborative research project led by University at Buffalo and Institute of Semiconductors (IoP) at Chinese Academy of Science (CAS).
Grover and GM colleagues Jian Gao, Venkatesh Gopalakrishnan, and Ramachandra Diwakar are using the Titan supercomputer at the Oak Ridge Leadership Computing Facility to improve combustion models for diesel passenger car engines with an ultimate goal of accelerating innovative engine designs while meeting strict emissions standards.
Nuclear physicists are using the nation's most powerful supercomputer, Titan, at the Oak Ridge Leadership Computing Facility (OLCF) to study particle interactions important to energy production in the Sun and stars and to propel the search for new physics discoveries. The research team using Titan, including principal investigator William Detmold of the Massachusetts Institute of Technology (MIT), is calculating proton-proton fusion--a process that powers the Sun and other stars in which two protons fuse to form a deuteron--and double beta decay, a rare process which occurs when an unstable nucleus decays by emitting two electrons with or without neutrinos (subatomic particles with near-zero mass).
