    Researchers characterize membrane behavior

    February 2, 2018

    An article authored by a team of LLNL scientists has characterized how different cell membranes behave. One of the team’s images from their work made the cover of the leading journal of quantitative biology.

    Superconductive Coatings May Float NIF Targets

    February 1, 2018

    Magnetic levitation is now, and it’s here. It’s been done with trains and even frogs; now it’s being attempted with tiny NIF fusion fuel capsules. The concept behind an ambitious NIF target fabrication program is to levitate inertial confinement fusion (ICF) capsules inside hohlraums, harnessing the physics of superconducting levitation.

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

    January 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 windows would convert the sunlight on bright days into energy that provides more functional integration with buildings, automobiles, information displays and potentially many other technologies.

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

    January 29, 2018

    DOE has awarded 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, will be done in collaboration with the San Francisco startup General Automation Lab Technologies.

    Looking to the sun to create hydrogen fuel

    January 17, 2018

    When Lawrence Livermore scientist Tadashi Ogitsu leased a hydrogen fuel-cell car, 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.

    Meteorites reveal story of Martian climate

    January 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 underwent this dramatic change in climate conditions.

    2017 Research Slam a hit

    September 14, 2017

    Intended to improve the communications skills of early career scientists, the Slam was open to all Livermore postdocs during the 2017 calendar year. Each presentation was allowed a maximum of three slides, and points were deducted from the score of any presentation that went over three minutes. The competition encouraged its participants to explain their science in simple language.
