versus producing oil. When algae are awake they grow; when they're asleep they produce oil.
Producing oil is part of the cells'survival strategy when it's under stress said Chia-Hong Tsai doctoral candidate with MSU's Department of energy Plant Research Laboratory
and Department of Plant Biology and co-author. They go into quiescence to conserve energy and nutrients.
But to convert them into truly viable biofuel producers we need them to grow and produce oil simultaneously.
The secret for making this happen was CHT7--the gatekeeper that cues cells to wake up
and is always active For biofuels this would remove a major hurdle and gives scientists a way to potentially produce high amounts of oil and biomass.
In terms of human medicine this discovery gives scientists a promising new model to study tumor suppression and growth.

The wavelengths that make Sagittarius A*visible are scattered by interstellar gas along the line of sight in the same way that light is scattered by fog On earth.
This will be important for future research on the gas near this black hole. This work is a good example of the synergy between different modern research infrastructures technologies and science ideas.

#Unique catalysts for hydrogen fuel cells synthesized in ordinary kitchen microwave oven Swedish and Chinese researchers show how a unique nano-alloy composed of palladium nano-islands embedded in tungsten nanoparticles creates a new type of catalysts for highly efficient oxygen reduction the most important reaction in hydrogen fuel cells.
Their results are published in the scientific journal Nature Communications. The world's rapidly growing demand for energy and the requirement of sustainable energy production calls for an urgent change in today's fossil fuel based energy system.
Research groups worldwide work intensively to develop novel advanced energy conversion and storage systems with high efficiency low cost and environmental compatibility.
Traditional fuel cells are limited however by the need of efficient catalysts to drive the chemical reactions involved in the fuel cell.
The anchoring keep the nanoparticles stable over long time by hindering them from fusing together in the fuel cell tests.
If we were not using argon as protective inert gas it would be fully possible to synthesize this advanced catalyst in my own kitchen!

The authors consider wind solar hydraulic nuclear coal and gas as potential energy sources. In their model the energy demand and availability are cast as random variables.
By a pipeline system fecal sludge of the hospital enters a two-stage unaerobic reactor where it is mixed with biowaste.
Bacteria decompose the mixture and produce among others the energy-rich gas of methane. It is used then for the gas stoves in the kitchen of the hospital.
In the region of Pucanganom we installed a system that processes toilet sewage of 15 families and the dung of their animals in three biogas facilities.
There the organic wastes are converted into biogas and fertilizer within a period of one month. Via a pipeline system the gas is passed directly on to the gas stoves of the neighboring houses.
The remaining sludge is dried and used as a fertilizer. At first we had to work hard to convince the population Fuchs says.

#Balancing birds and biofuels: Grasslands support more species than cornfields In Wisconsin bioenergy is for the birds.
These grassland fields can also produce ample biomass for renewable fuels. Monica Turner UW-Madison professor of zoology and study lead author Peter Blank a postdoctoral researcher in her lab hope the findings help drive decisions that benefit both birds
and biofuels too by providing information for land managers farmers conservationists and policy makers as the bioenergy industry ramps up particularly in Wisconsin and the central U s as bioenergy production demand increases we should pay attention to the ecological consequences says Turner.
According to Blank and Turner the study is one of the first to examine grassland fields already producing biomass for biofuels
While previous studies suggest corn is a more profitable biofuel crop than grasses and other types of vegetation the new findings indicate grassland fields may represent an acceptable tradeoff between creating biomass for bioenergy and providing habitat for grassland birds.

In addition, they asked the participants what kind of frying fat/oils they usually used at home, with the possible responses as follows:
Frying deteriorates oils through the processes of oxidation and hydrogenation, leading to an increase in the absorption of oil degradation products by the foods being fried,
and also a loss of unsaturated fatty acids such as linoleic and linolenic acids and an increase in the corresponding trans fatty acids such as trans-linoleic acids and trans-linolenic acids."
"Deterioration of oils during frying is more profound when the oils are reused, a practice more common away from home than at home.
This may partly explain why we observed a stronger association of GDM risk with fried foods consumed away from home than fried foods consumed at home."

and laser pioneer Frank Tittel and his group uses a thumbnail-sized quantum cascade laser (QCL) as well as tuning forks that cost no more than a dime to detect very small amounts of nitrous oxide and methane.
and found it capable of detecting trace amounts of methane, 13 parts per billion by volume (ppbv),
"Methane and nitrous oxide are both significant greenhouse gases emitted from human activities, "Tittel said.""Methane is emitted by natural sources, such as wetlands,
and human activities, such as leakage from natural gas systems and the raising of livestock.""Human activities such as agriculture, fossil fuel combustion, wastewater management and industrial processes are increasing the amount of nitrous oxide in the atmosphere.
The warming impact of methane and nitrous oxide is more than 20 and 300 times, respectively, greater compared to the most prevalent greenhouse gas, carbon dioxide over a 100-year period.
For these reasons, methane and nitrous oxide detection is crucial to environmental considerations.""The small QCL has only become available in recent years,
Tittel said, and is far better able to detect trace amounts of gas than lasers used in the past.
Previous versions of the QCL are just as effective, but far too bulky for mobile use.
What makes the technique possible is the small quartz tuning fork, which vibrates at a specific frequency when stimulated."
When light at a specific wavelength is absorbed by the gas of interest, localized heating of the molecules leads to a temperature

That signal is proportional to the gas concentration.""The unit can detect the presence of methane or nitrous oxide in as little as a second,
he said. To field test the device, the Rice team installed it on a mobile laboratory used during NASA's DISCOVER-AQ campaign, which analyzed pollution on the ground and from the air last September.
"This was a milestone for trace-gas sensing, "Ren said.""Now we're trying to minimize the size of the whole system."

#Leaked EU documents rank biofuel emissions higher than crude oil European union politics website Euractive has gotten its hands on official EU data reporting that many biofuel crops release more carbon dioxide than crude oil,
and approximate the emissions of the much-maligned oil mined from tar sands. The numbers were intended for release in the spring when the EU presents new proposals on biofuels,
and an official spokesperson refused to comment to Euractive. The European commission has defended long biofuels, despite dissent from Greenpeace and other environmental organizations.
Its current biofuel roadmap demands that at least 5. 75%of all energy sold on the market of any member country be biofuel
boosted to 10%by 2020. However, also in the biofuel directive is that biofuel production should be sustainable,
and the new numbers suggest that it is not. The leaked data present higher carbon costs for biofuels because, for the first time,
the analysts incorporated the effects of indirect land use change (ILUC). ILUC is the rise in emissions
when forests and wetlands are destroyed to clear land to grow biofuel crops. And with ILUC added to the mix, it looks like some top biofuel crops are worse for the environment, in terms of carbon emissions, than crude oil.
The EU's default value for measuring carbon efficiency for oil from tar sands is 107g CO2 equivalent per megajoule of fuel (CO2/mj.
Meanwhile, crude oil's efficiency value is 87. 5g CO2/mj. Here are the data (g CO2/mj) from the EU documents,
incorporating ILUC, for various biofuel crops, thanks to Euractive: Palm oil-105g Soybean-103g Rapeseed-95g Sunflower-86g Palm oil with methane capture-83g Wheat (process fuel not specified)- 64g Wheat (as process fuel natural gas used in CHP)- 47g
Corn (Maize)- 43g Sugar cane-36g Sugar beet-34g Wheat (straw as process fuel in CHP plants)- 35g 2g Ethanol (land-using)- 32g 2g Biodiesel (land-using)- 21g 2g Ethanol

and decide to take action on them, it's not clear what they should do.

The extraction of the hydrogen from the diesel fuel happens through autothermal reforming, a catalytic reaction in
which the diesel fuel is decomposed into hydrogen, steam, carbon dioxide, and carbon monoxide. The CO is converted then to CO2
It didn escape their notice that the extraction of hydrogen from the diesel fuel releases CO2 directly into the atmosphere. ctually all carbon in the diesel is converted to CO2,

Such advances might eventually make solar power cheaper than fossil fuels, even without Semprius technology. But silicon-based solar power is not yet there,
The U s. Energy Information Administration estimates that new solar power plants will produce power at just under 15 cents per kilowatt-hourar higher than the 6. 5 cents per kilowatt-hour for natural gas power.
Besides a small rise in the price of natural gas and slightly cheaper coal, the weather played the biggest role in in pushing up emissions,

The first customers will probably be oil gas and mining companies that use large generators to produce power in remote areas.
The generator could save those companies millions in fuel Scullin says. There aren t many levers these companies can pull to reduce costs that much he adds.
Even improved thermoelectric materials however are unlikely to reduce fuel consumption by more than 5 or 10 percent.
