Berkeley Lab Startup Wants to Know How Damaged Your DNA Is

Exogen can check the DNA health not only of an individual but that of an entire region, thus answering questions on the impact of environmental events.

Currently if a scientist or doctor wanted to measure the level of a person’s DNA damage, they would have to look at some cells in a fluorescent microscope and manually count the number of DNA breaks. This kind of counting is labor-intensive, time-consuming, and a highly subjective process. Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Sylvain Costes, who has spent over a decade studying the effects of low-dose radiation on cellular processes, came up with a way to automate the job using a proprietary algorithm and a machine to scan specimens and objectively score the damaged DNA.

Potential for Storing Meltwater Important for Calculating Sea-Level Rise

Researchers at the University of Utah have discovered a new aquifer in the Greenland Ice Sheet that holds liquid water all year long in the otherwise perpetually frozen winter landscape. The aquifer is extensive, covering 27,000 square miles.

The reservoir is known as a “perennial firn aquifer” because water persists within the firn – layers of snow and ice that don’t melt for at least one season. Researchers believe it figures significantly in understanding the contribution of snowmelt and ice melt to rising sea levels. (more…)

A Living Desert Underground

In the perpetual darkness of a limestone cave, UA researchers have discovered a surprisingly diverse ecosystem of microbes eking out a living from not much more than drip water, rock and air. The discovery not only expands our understanding of how microbes manage to colonize every niche on the planet but also could lead to applications ranging from environmental cleanup solutions to drug development.

Hidden underneath the hilly grasslands studded with ocotillos and mesquite trees in southeastern Arizona lies a world shrouded in perpetual darkness: Kartchner Caverns, a limestone cave system renowned for its untouched cave formations, sculpted over millennia by groundwater dissolving the bedrock and carving out underground rooms, and passages that attract tourists from all over the world.

USGS Releases First Assessment of Shale Gas Resources in the Utica Shale: 38 trillion cubic feet

The Utica Shale contains about 38 trillion cubic feet of undiscovered, technically recoverable natural gas (at the mean estimate) according to the first assessment of this continuous (unconventional) natural gas accumulation by the U. S. Geological Survey. The Utica Shale has a mean of 940 million barrels of unconventional oil resources and a mean of 208 million barrels of unconventional natural gas liquids.

The Utica Shale lies beneath the Marcellus Shale, and both are part of the Appalachian Basin, which is the longest-producing petroleum province in the United States. The Marcellus Shale, at 84 TCF of natural gas, is the largest unconventional gas basin USGS has assessed. This is followed closely by the Greater Green River Basin in southwestern Wyoming, which has 84 TCF of undiscovered natural gas, of which 82 TCF is continuous (tight gas). (more…)

‘Fingerprinting’ Method Tracks Mercury Emissions from Coal-Fired Power Plant

ANN ARBOR, Mich.— For the first time, the chemical “fingerprints” of the element mercury have been used by University of Michigan researchers to directly link environmental pollution to a specific coal-burning power plant.

The primary source of mercury pollution in the atmosphere is coal combustion. The U-M mercury-fingerprinting technique – which has been under development for a decade – provides a tool that will enable researchers to identify specific sources of mercury pollution and determine how much of it is being deposited locally.

Berkeley Lab to Build Cost Model for Fuel Cells

*A $2-million award from DOE will help bring down the cost of next-generation fuel cells.*

Fuel cells seem like an ideal energy source—they’re clean, efficient, silent and don’t require transmission lines. The hitch? They can be costly. Now scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) hope to change that equation by building a sophisticated cost model that will take into account the total cost of ownership.

With a $2-million grant from the U.S. Department of Energy, a team of scientists led by Eric Masanet will perform a detailed assessment of fuel cell design and manufacturing that takes into account both intrinsic and external benefits. The aim is to quantify not only traditional manufacturing costs but also benefits that may previously have been overlooked and may ultimately bring down the cost of fuel cells. (more…)

USGS Releases New Assessment of Gas Resources in the Marcellus Shale, Appalachian Basin

The Marcellus Shale contains about 84 trillion cubic feet of undiscovered, technically recoverable natural gas and 3.4 billion barrels of undiscovered, technically recoverable natural gas liquids according to a new assessment by the U. S. Geological Survey (USGS).

These gas estimates are significantly more than the last USGS assessment of the Marcellus Shale in the Appalachian Basin in 2002, which estimated a mean of about 2 trillion cubic feet of gas (TCF) and 0.01 billion barrels of natural gas liquids. (more…)
