For example we're discussing what standards the aviation sector should recognize to meet their sustainability expectations.
She stressed that international harmonization is vital for the aviation industry because of looming compliance mandates for carbon reductions in Europe.
To land a plane in Europe U s. carriers will have to prove that they have reduced their carbon footprint below a certain level.
Although the requirement has been postponed until January 2014 the aviation sector is actively seeking ways to reduce greenhouse gas emissions through biofuels.
Nitrogen oxides are created pollutants by cars trucks aircrafts coal plants and other large scale sources. The work presents a dramatic new wrinkle in the arguments for reducing man-made pollutants worldwide said Surratt whose work was published this month in the Proceedings of the National Academy of Sciences.
which enabled the measurement of single brain cells during flight. The question of how animals orient themselves in space has been studied extensively
In other words their normal flight patterns are one-dimensional while the experiment required their flights to fill a three-dimensional space.
The solution was to be found in a previous study in Ulanovsky's group which tracked wild fruit bats using miniature GPS devices.
The researchers note that for those non-flying animals that essentially move in flat space the different axes might not be perceived at the same resolution.
To a large extent this is due to the development of innovative technology that allowed the first glimpse into the brain of a flying animal.

UAVSAR uses a technique called interferometry that sends microwave energy pulses from the sensor on the aircraft to the ground.
#Green pea galaxies could help astronomers understand early universethe rare Green pea galaxies discovered by the general public in 2007 could help confirm astronomers'understanding of reionization a pivotal stage in the evolution of the early universe
and forming the first galaxies. During this period the space between the galaxies changed from an opaque neutral fog to a transparent charged plasma as it is today.
Plasma is gas that's electrically charged. As for how this happened the prevailing theory holds that massive stars in the early galaxies produced an abundance of high-energy ultraviolet light that escaped into intergalactic space.
There the UV light interacted with the neutral hydrogen gas it met blasting electrons off the hydrogen atoms and leaving behind a plasma of negatively charged electrons and positively charged hydrogen ions.
when we looked at galaxies nearby the high-energy radiation doesn't appear to make it out.
There's been a push to find some galaxies that show signs of radiation escaping said Anne Jaskot a doctoral student in astronomy.
The Green peas are compact highly star-forming galaxies that are very similar to the early galaxies in the universe Jaskot said.
The researchers focused on six of the most intensely star-forming Green pea galaxies which are between one billion and five billion light years away.
and in this case they helped the astronomers understand the relationship between the stars and gas in these galaxies.
and Oey how much light the galaxies absorbed. Then to determine how much light was there to start with they ran models to estimate for example how old the galaxies are
and how many stars they contain. The galaxies the researchers determined produced more radiation than the researchers detected so they infer that some of it must have escaped.
An analogy might be if you have a tablecloth and you spill something on it. If you see the cloth has been stained all the way to the edges there's a good chance it also spilled onto the floor Jaskot said.
We're seeing that the galaxy is saturated with it and there's probably some extra that spilled off the edges.

and aviation and allows regulated sources to trade emission allowances. Advice commonly given to consumers includes reducing the number of flights taken replacing energy-hungry appliances and lightbulbs with energy efficient ones and eating less red meat.

because in contrast to electricity production and aviation emissions from agriculture are covered not by the EU ETS.
However additional emissions of flights are fully offset by the EU ETS even without buying the offsets offered by most airlines
--and also to contribute to research aimed at designing quieter aircraft engines. The physics of noisethe exhausts of high-performance aircraft at takeoff and landing are among the most powerful human-made sources of noise.
For ground crews even for those wearing the most advanced hearing protection available this creates an acoustically hazardous environment.
To the communities surrounding airports such noise is a major annoyance and a drag on property values.
Understandably engineers are keen to design new and better aircraft engines that are quieter than their predecessors.
New nozzle shapes for instance can reduce jet noise at its source resulting in quieter aircraft.
In addition to jet noise simulations Stanford researchers in the Predictive Science Academic Alliance Program (PSAAP) sponsored by the Department of energy are using the Charles code to investigate advanced-concept scramjet propulsion systems used in hypersonic flight
(with video)--flight at many times the speed of sound --and to simulate the turbulent flow over an entire airplane wing.

#Astronomers complete cosmic dust censusan international team of astronomers has completed a benchmark study of more than 300 galaxies producing the largest census of dust in the local Universe the Herschel Reference Survey.
Led by Dr Luca Cortese from Swinburne University of Technology in Melbourne Australia the team used the Herschel Space Observatory to observe galaxies at far-infrared
and physical properties in galaxies other than our own Milky way said Dr Cortese'Cosmic dust is heated by starlight to temperatures of only a few tens of degrees above absolute zero
and SPIRE data shows that the properties of grains vary from one galaxy to another--more than we originally expected.
As dust is heated by starlight we knew that the frequencies at which grains emit should be related to a galaxy's star formation activity.
However our results show that galaxies'chemical history plays an equally important role commented Dr Cortese.
It is particularly an issue for the most distant galaxies which have a star formation and chemical history significantly different to the one in our own Milky way.
The data obtained for the Herschel Reference Survey have been made publicly available to allow further studies of dust properties in nearby galaxies.
will help astronomers to further unveil the mystery of cosmic dust in galaxies in the years to come.
