Drones deliver green transportation option

Feb. 13, 2018 -  
By getting your next package delivered by drone, you could be saving energy, but only if companies deploy drones sensibly. New research by Lawrence Livermore National Laboratory ( LLNL ), Carnegie Mellon University , SRI International and the University of Colorado at Boulder shows that drone-based...

Protein that prevents further cartilage damage

Feb. 12, 2018 -  
There may be a protein in the body that hinders cartilage degradation in patients with a torn anterior cruciate ligament (ACL). Lawrence Livermore National Laboratory ( LLNL ) scientists performed in vivo experiments on animal models of post traumatic osteoarthritis and found that sclerostin (a...

Hayward fault earthquake simulations increase fidelity of ground motions

Feb. 8, 2018 -  
In the next 30 years, there is a one-in-three chance that the Hayward fault will rupture with a 6.7 magnitude or higher earthquake, according to the U nited States Geologic Survey (USGS). Such an earthquake will cause widespread damage to structures, transportation and utilities, as well as...

First experimental evidence for superionic ice

Feb. 5, 2018 -  
Among the many discoveries on matter at high pressure that garnered him the Nobel Prize in 1946, scientist Percy Bridgman discovered five different crystalline forms of water ice, ushering in more than 100 years of research into how ice behaves under extreme conditions. One of the most intriguing...

Researchers characterize membrane behavior

Feb. 2, 2018 -  
An article authored by a team of Lawrence Livermore National Laboratory ( LLNL ) scientists has characterized how different cell membranes behave. “Different membranes in different parts of the body have different barrier strengths that are required for drugs to penetrate them to reach the organ,”...

Scientists discover ideal material for smart windows that convert sunlight to electricity

Jan. 30, 2018 -  
Imagine a smart window that becomes transparent when it is dark or cool but darkens when the sun is bright, converting that sunlight into electricity. Typical smart windows absorb or reflect sunlight without actually converting the solar energy into a useful form. However, the new photovoltaic...

Lab earns DOE grant for collaboration to improve growth, efficiency of biofuel-producing algae

Jan. 29, 2018 -  
The Department of Energy has awarded Lawrence Livermore National Laboratory ( LLNL ) a three-year, $1.5 million grant to improve the growth and efficiency of biofuel-producing algae through the alteration of their microbiomes. The work, which is led at LLNL by Xavier Mayali and Ty Samo in the...

Alan Hidy's global travels lead to a CAMS career

Jan. 22, 2018 -  
The bookcase in Alan Hidy’s office is loaded with carefully labeled bags of rocks -- some the size of a fist, others pulverized into dust. The granite in these bags is destined for isotope ratio measurement at Lawrence Livermore National Laboratory's Center for Accelerator Mass Spectrometry ( CAMS...

Looking to the sun to create hydrogen fuel

Jan. 17, 2018 -  
When Lawrence Livermore scientist Tadashi Ogitsu leased a hydrogen fuel-cell car in 2017, he knew that his daily commute would change forever. There are no greenhouse gases that come out of the tailpipe, just a bit of water vapor. The market for hydrogen cars is growing. According to a recent...

Meteorites reveal story of Martian climate

Jan. 9, 2018 -  
Liquid water is not stable on Mars’ surface because the planet’s atmosphere is too thin and temperatures are too cold. However, at one time Mars hosted a warm and wet surface environment that may have been conducive to life. A significant unanswered question in planetary science is when Mars...
