From Soil Microbe to Super-Efficient Biofuel Factory?

Berkeley Lab-led team explores a way to create biofuels, minus the photosynthesis

Is there a new path to biofuels hiding in a handful of dirt? Lawrence Berkeley National Laboratory (Berkeley Lab) biologist Steve Singer leads a group that wants to find out. They’re exploring whether a common soil bacterium can be engineered to produce liquid transportation fuels much more efficiently than the ways in which advanced biofuels are made today.

The scientists are working with a bacterium called Ralstonia eutropha. It naturally uses hydrogen as an energy source to convert CO2 into various organic compounds. (more…)

Did Bone Ease Acid for Early Land Crawlers?

In a new paper in the Proceedings of the Royal Society B, scientists propose that the bony structures in the skin of many early four-legged creatures might have been there to relieve acid buildup in bodily fluids. Analysis of their anatomy suggests that as they ventured out of water, the animals would have had trouble getting rid of enough CO2 to prevent acid buildup.

PROVIDENCE, R.I. [Brown University] — Here’s an anatomical packing list for making that historic trip from water to land circa 370 million years ago: Lungs? Check. Legs? Check. Patches of highly vascular bone in the skin? In a new paper, scientists propose why many of the earliest four-legged creatures that dared breathe on land carried bony skin features. (more…)

IBM and ZSE Create Virtual Green Highway for Electric Vehicles

*E-Mobility Project Identifies EV Charging Station Options between Two Cities*

Armonk, NY and Slovakia – 09 Apr 2012: IBM today announced it has teamed with Západoslovenská energetika, a.s. (ZSE), the largest distributor and supplier of electricity in Slovakia, on a smart energy “feasibility” study that will help prepare the capital city Bratislava for electric vehicles (EVs).

Using e-mobility technology, the study will help identify the possibilities of connecting two neighboring metropolitan areas – Bratislava, Slovakia and Vienna, Austria with a “green” highway. This highway will interconnect the two cities with a network of public charging stations for electric vehicles. (more…)

Thawing Permafrost 50 Million Years Ago Led To Warm Global Events, Says New Study

A new study led by the University of Massachusetts Amherst and involving the University of Colorado Boulder proposes a simple new mechanism to explain the source of carbon that fed a series of extreme warming events on Earth about 50 million years ago called the Paleocene-Eocene Thermal Maximum, or PETM, as well as a sequence of similar, smaller warming events afterward.

“The standard hypothesis has been that the source of carbon was in the ocean in the form of frozen methane gas in ocean-floor sediments,” said lead study author Rob DeConto of the University of Massachusetts Amherst. “We are instead ascribing the carbon source to the continents in polar latitudes where permafrost can store massive amounts of carbon that can be released as CO2 when the permafrost thaws.” (more…)

UCLA Engineering Researchers Use Electricity to Generate Alternative Fuel

Imagine being able to use electricity to power your car — even if it’s not an electric vehicle. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have for the first time demonstrated a method for converting carbon dioxide into liquid fuel isobutanol using electricity.

Today, electrical energy generated by various methods is still difficult to store efficiently. Chemical batteries, hydraulic pumping and water splitting suffer from low energy-density storage or incompatibility with current transportation infrastructure. (more…)

U of T Engineering Professor Develops Microfluidic Chips for Bitumen Gas Analysis

*Device could save time and money for oil/gas industry*

Mechanical engineering professor David Sinton and his research team have developed a process to analyze the behaviour of bitumen in reservoirs using a microfluidic chip, a tool commonly associated with the field of medical diagnostics. The process may reduce the cost and time of analyzing bitumen-gas interaction in heavy oil and bitumen reservoirs.

Sinton and post-doctoral researcher Hossein Fadaei are using the chips to examine the way highly pressurized carbon dioxide (CO2) behaves when injected into bitumen, which is a type of petroleum. The new method, reported in the journal Energy & Fuels, could streamline the way fossil energy companies measure how gases move within heavier oils like bitumen. (more…)

From Cancer Research to Energy Storage, Berkeley Lab Scientist Takes on Big Challenges

*Rizia Bardhan, a postdoc at the Molecular Foundry, selected to Forbes’ ’30 under 30′ list*

On a typical day, Rizia Bardhan walks through the doors of Lawrence Berkeley National Laboratory’s Molecular Foundry and immerses herself in the tricky business of tweaking optical spectroscopy equipment to study phase transitions in metal hydrides.

It’s fair to say that what she does is difficult to grasp. Why she does it is easy: “I want to help solve big problems. That’s why I’m here,” she says. (more…)

Long-Term Carbon Storage in Ganges Basin May Portend Global Warming Worsening

Woods Hole Oceanographic Institution (WHOI) scientists have found that carbon is stored in the soils and sediments of the Ganges-Brahmaputra basin for a surprisingly long time, making it likely that global warming could destabilize the pool of carbon there and in similar places on Earth, potentially increasing the rate of CO2 release into the atmosphere.

The study, published in the current online edition of Nature Geoscience, examined the radiocarbon content of river sediments collected from the Ganges-Brahmaputra system draining the Himalayas. The basin, the scientists say, “represents one of the largest sources of terrestrial biospheric carbon to the ocean.” (more…)
