Lada has removable root modules in which astronauts are able to grow several generations of crops before the modules'nutrients are used up.
At that point the astronauts send the modules back to Earth for analysis. Biologists On earth examine the modules to see
if any harmful microbes have grown on them. They also check the modules and the plants'leaves for contaminants
which may come from the space station's environment. These are the same types of tests we routinely conduct on the food grown On earth Bugbee says.

or diesel vehicles researchers at the Georgia Institute of technology are offering some advice: comparisons of the energy consumption greenhouse gas emissions and total cost of ownership for the medium-duty vehicles.
The advantages of electric versus diesel depend largely on how the trucks will be used--the frequency of stops
In city driving with frequent stops the electric trucks clearly outperform diesel vehicles. On average in the United states electric urban delivery trucks use about 30 percent less total energy
and the regenerative braking systems in electrical vehicles help provide better efficiency. However electric delivery trucks lose their advantage in suburban routes that involve fewer stops and higher average speed.
Electric vehicles have limited a daily range and top speed and without a lot of stops lose their regenerative braking advantage.
Electric vehicles can cost more than their diesel counterparts under certain conditions particularly if high-cost charging systems are used
The relative benefits of the electric vehicles the researchers found depend on vehicle efficiency associated with drive cycle diesel fuel price travel demand electric drive battery replacement
The research team took into account the sources of electricity used to charge the electric vehicles in evaluating greenhouse gas emissions.
Electricity produced from hydroelectric sources--more common in the northwest United states--dramatically reduced total greenhouse gas emissions for electric vehicles operated there.
Vehicles operated in states heavily dependent on coal for producing electricity showed higher emissions. In every state in the U s. electric trucks provided some reduction in greenhouse gas emissions with urban routes providing the most advantage.
or more compared to diesel vehicles. Wild cards in the study included the future costs of both diesel fuel
Battery price reductions down the road could have a large effect on the cost-competitiveness of electric trucks
because vehicles in these applications tend to travel the same routes each day spend significant amounts of time in stop
The two trucks had approximately the same gross vehicle weight curb weight and payload. The comparison controlled for improvements in diesel efficiency between 2006 and 2011.
The researchers were surprised to find that the electric truck had cost advantages over the diesel vehicle under some conditions.
They had expected that costs would always be higher for the electric vehicle especially since the purchase price of the electric truck studied was higher than the diesel truck
which the total cost of operating an electric vehicle is less than operating a diesel vehicle noted Marilyn Brown another co-author and a professor in Georgia Tech's School of Public Policy.
Our expectation was that the electric vehicle would provide environmental benefits but at a cost.
Depending on what happens with vehicle and fuel costs the advantages could swing even farther in the direction of electric vehicles.
The relative benefit of electric trucks over diesel counterparts could be much more significant than one might expect said Lee.

#Serengeti road divides biologists: Will a road across the northern tier of Serengeti National park ruin it?
Serengeti National park in Tanzania may be the most iconic national park in the world. Here lions leopards elephants hippos and giraffes wander free.
and Travel to address this the Tanzania government now plans to build a gravel road across 50 km of the northern part of the park to link the country's coast to Lake victoria
International outcry Plans for the road have raised an international outcry. The fear is that the road
which bisects the wildebeest migration route near the Kenyan border will bring an end to the annual migrations
The proposed road could lead to the collapse of the largest remaining migratory system On earth the scientists wrote led by Andrew Dobson from Princeton university.
and there is a need for new roads. A broader perspective Røskaft is co-coordinator of a partnership between the Tanzania Wildlife Research Institute
and NTNU that is studying the region where the road will be built. The studies provide a snapshot of the area before road construction
and will be continued after the road is built. That gives scientists the ability to detect possible problems before they get out of control Røskaft says.
Road construction clearly will have impacts adds Røskaft but it is important to see the road from a broader perspective.
In some ways he says argument over the road distracts scientists and policymakers from far more serious threats.
Here road building ranks far lower as a threat than issues such as climate change poverty high population densities
The existing road system is also problematic Røskaft says. It bisects the wilde beest calving areas
and traffic in the park has tripled over recent years with 120000 vehicles entering the park in 2011 alone.
Fully 85 per cent of these are tourist vehicles. Thus he says the new road might take some of the pressure off the roads that cross calving areas.

Similar to the chloroplasts in green plants that carry out photosynthesis our artificial photosynthetic system is composed of two semiconductor light absorbers an interfacial layer for charge transport
and produce charge-carriers to drive separate water reduction and oxidation half-reactions. In natural photosynthesis the energy of absorbed sunlight produces energized charge-carriers that execute chemical reactions in separate regions of the chloroplast Yang says.
We've integrated our nanowire nanoscale heterostructure into a functional system that mimics the integration in chloroplasts
When sunlight is absorbed by pigment molecules in a chloroplast an energized electron is generated that moves from molecule to molecule through a transport chain until ultimately it drives the conversion of carbon dioxide into carbohydrate sugars.
This electron transport chain is called A z-scheme because the pattern of movement resembles the letter Z on its side.
The majority charge carriers from both semiconductors recombine at the ohmic contact completing the relay of the Z-scheme similar to that of natural photosynthesis. Under simulated sunlight this integrated nanowire-based artificial photosynthesis system
This is important because it provides the earliest archaeological evidence of this type of resource transport behavior in the human lineage.

and fuel demandsnew discoveries of the way plants transport important substances across their biological membranes to resist toxic metals
That's the conclusion of 12 leading plant biologists from around the world whose laboratories recently discovered important properties of plant transport proteins that collectively could have a profound impact on global agriculture.
These membrane transporters are a class of specialized proteins that plants use to take up nutrients from the soil transport sugar
One of Schroeder's research advances led to the discovery of a sodium transporter that plays a key role in protecting plants from salt stress
and her colleagues have utilized now this type of sodium transporter in breeding research to engineer wheat plants that are more tolerant to salt in the soil boosting wheat yields by a whopping 25 percent in field trials.
Other recent transport protein developments described by the biologists have been shown to increase the storage of iron
The scientists also discovered transporters in plants and symbiotic soil fungi that allow crops to acquire phosphate--an element essential for plant growth
The biologists said crops could be made more efficient in using water through discoveries in plant transport proteins that regulate the stomatal pores in the epidermis of leaves where plants lose more than 90 percent of their water through transpiration.
A recent discovery of protein transporters that move sugar throughout the plant has been used to develop rice plants that confer pest resistance to crops the biologists said providing a novel way to simplify the engineering of crops with high yields and pest resistance
or new transporters to make them work harder on existing agricultural land said Dale Sanders director of the John Innes Centre in the U k
These recent developments in understanding the biology of plant transporters are leading to improved varieties less susceptible to adverse environments and for improving human health.
