Marquez Floats Ideas about Underwater Data Centers in IEEE Spectrum
In a discussion about Microsoft’s Project Natick, where the computing giant is examining the viability of underwater data centers, Andres Marquez, a research scientist and Advanced Architectures Team Leader in the Advanced Computing, Mathematics, and Data Division’s High Performance Computing group, spoke to IEEE Spectrum about how these undersea facilities could “play an important role in meeting the world’s growing demand for Internet services.” He also touched on how the salty ocean presents other problems when it comes to protecting data servers over time.
Phil Rasch Selected for Eos Editorial Advisory Board
Congratulations to Dr. Philip
Rasch, atmospheric scientist and Lab fellow at Pacific Northwest National
Laboratory. Rasch was selected to serve as a member of the Eos Editorial
Advisory Board representing the American Geophysical Union's (AGU) Global Environmental Change focus group and

Kravitz Provides Geoengineering Insight for Slate
When the e-zine Slate
needed expertise to explain geoengineering and climate modeling for a recent
article, they turned to Dr.

Long-Lived Traveling Particles to be Tracked
by the human eye are plentiful microscopic particles, small but mighty
polycyclic aromatic hydrocarbons, or PAHs, constantly emitted into the air from
a variety of combustion sources. Power plants, forest and brush fires,
wood-burning fireplaces, and even the backyard barbeque launch a soupy swell of
chemicals into the atmosphere, all bundled into aerosol particles. These trace aerosol
components are highly toxic and are believed to increase human risk for cancer.
They enter the atmosphere, but how do they get there? And where do they go?
The Dark Side of Cold Clouds
Those airy, wispy cirrus clouds you're contemplating could
be concealing a dirty secret. High in the atmosphere, these icy clouds can take
on traveling soot, expelled from diesel trucks, ship boilers, forest fires, and
fireplaces. What eventually drops from the cloud's sooty load may affect the
destiny of snow-capped peaks and frozen glaciers in the Arctic.
Ruby Leung Appointed ACME's Chief Climate Scientist
Dr. L. Ruby Leung, an internationally renowned atmospheric scientist
specializing in climate modeling and the water cycle, and Laboratory Fellow at
Pacific Northwest National Laboratory, has been selected by the Department
of Energy to lead the Accelerated Climate Modeling for Energy
(ACME) project as Chief Climate
Scientist. In this role, Leung will help guide the science behind one of DOE’s most
important areas of research: transforming the Nation’s ability to predict
climate change and its impacts.

Microbes Take Their Vitaminsfor the Good of Science

Captured by the Game
Results: While the notion of “players,” “actions,” and “payoffs” may seem more suited to Las Vegas gaming tables, game theory as a mathematical tool has steadily grown in cyber defense applications. In ongoing and progressive work being conducted under PNNL’s Asymmetric Resilient Cybersecurity initiative, scientists have taken on the challenge of addressing the sources and types of uncertainty that can arise in realizing a resilient cyber system. Already, their work on quantifying uncertainties in cyber attacker payoffs within randomly determined security games has been recognized with an IEEE Best Paper award. Meanwhile, their latest publication presents a probabilistic modeling framework for representing and propagating uncertainties in cyber attacker payoffs with the added goal of increasing awareness among researchers about this problem domain.
Invited Review Highlights Mass Spec Imaging Developments, Applications
Two powerhouses in the analytical sciences
world, mass spectrometry and microscopic imaging, have been combined to make an
even more impactful capability: mass spectrometry imaging (MSI). This technique
allows scientists to locate and identify hundreds of molecules in complex
samples without using a labeling compound. Applications include understanding
microbial communication and microbial-plant interactions, localization of drugs
in tissues for clinical and forensics research, and mapping biomolecules in
tissues for understanding health and disease.
