'Human-on-a-chip' could replace animal testing

June 2, 2016- 
Development of new prescription drugs and antidotes to toxins currently relies extensively on animal testing in the early stages of development, which is not only expensive and time consuming, it can give scientists inaccurate data about how humans will respond to such agents. But what if researchers could predict the impacts of potentially harmful chemicals, viruses or drugs on human beings...

Team IDs gene involved with fracture healing

June 1, 2016- 
New identification of a gene involved in the fracture healing process could lead to the development of new therapeutic treatments for difficult-to-heal injuries.Fracture healing involves communication between bone, muscle, vasculature and the thin membrane covering the outer surface of bones (periosteum) during the fracture repair. The periosteum contains stem cells that migrate to the...

Researchers reveal new electron ring formations

Aug. 11, 2015- 
Laser wakefield acceleration, a process where electron acceleration is driven by high-powered lasers, is well-known for being able to produce high-energy beams of electrons in tabletop-scale distances. However, in recent experiments, a team of scientists from Lawrence Livermore National Laboratory (LLNL) and the University of California, Los Angeles (UCLA) revealed new, never-before-seen...

New experimental and theoretical research could help make more efficient windows

July 27, 2015- 
By tightly integrating experimental and theoretical techniques, a Lawrence Livermore National Laboratory team has provided fundamentally new insights into the specific factors that determine the absorption characteristics of copper complexes. The results demonstrate that conventional interpretations based on "ligand field theory" -- a staple concept in inorganic chemistry -- are insufficient...

Soil organic matter vulnerable to climate change

March 31, 2015- 
Soil organic matter, long thought to be a semi-permanent storehouse for ancient carbon, may be much more vulnerable to climate change than previously thought.Plants direct between 40 percent and 60 percent of photosynthetically fixed carbon to their roots and much of this carbon is secreted and then taken up by root-associated soil microorganisms. Elevated carbon dioxide (CO2) concentrations...

New research could lead to more efficient electrical energy storage

March 4, 2015- 
Lawrence Livermore researchers have identified electrical charge-induced changes in the structure and bonding of graphitic carbon electrodes that may one day affect the way energy is stored.The research could lead to an improvement in the capacity and efficiency of electrical energy storage systems, such as batteries and supercapacitors, needed to meet the burgeoning demands of consumer...
