Pig bones have been found in abundance at Philistine archaeological sites along Israel's southern coastal plane dating from the beginning of the Iron age around 1150 to 950 BCE.
Such failures can be life-limiting situations for a lot of materials Demkowicz says including materials used in aircraft oil wells and other critical industrial applications.

In the case of the Voyager 1 crossing the heliopause separates material created by the sun from material that surrounds the stars throughout the galaxy.
and where we're going in our journey through the galaxy. Additionally scientists now gain deeper insight into the dynamic nature of the interstellar winds
Observations of atmospheric carbon dioxide made by aircraft at altitudes between 3 and 6 kilometers (10000-20000 feet) show that seasonal carbon dioxide variations have changed substantially during the last 50 years.
The amplitude increased by roughly 50 percent across high latitude regions north of 45°N compared with previous aircraft observations from the late 1950s and early 1960s.
Taking advantage of the long-duration and high-altitude-profiling capabilities of the NSF Gulfstream V aircraft also known as HIAPER the HIPPO project was designed to take a'snapshot'of the global troposphere Earth's lowest atmospheric
In the study the scientists compared the recent aircraft data with aircraft data gathered from 1958 to 1961 using U s. Air force weather reconnaissance flights.
These aircraft measurements were done at the time Charles Keeling was beginning continuous carbon dioxide measurements at Mauna loa Hawaii.
While the Mauna loa measurements are recognized now widely as the Keeling Curve the early aircraft data were forgotten all but.
The aircraft repeatedly ascended and descended from a few hundred meters to roughly 12 kilometers (40000 feet) in the skies between the North pole and Antarctica.
The aircraft-based observations uniquely show the large area in northern high latitudes where carbon dioxide amplitude increased strongly since 1960.

#Dusty surprise around giant black holeeso's Very Large Telescope Interferometer has gathered the most detailed observations ever of the dust around the huge black hole at the centre of an active galaxy.
Over the last twenty years astronomers have found that almost all galaxies have a huge black hole at their centre.
But new observations of a nearby active galaxy called NGC 3783 harnessing the power of the Very Large Telescope Interferometer (VLTI) at ESO's Paranal Observatory in Chile 2 have given a team of astronomers a surprise.

Onboard the plane sophisticated instruments sniff the atmosphere for greenhouse gases. They include a very sensitive spectrometer that analyzes sunlight reflected from Earth's surface to measure atmospheric carbon dioxide methane and carbon monoxide.
Other instruments analyze air samples from outside the plane for the same chemicals. Aircraft navigation data and basic weather data are collected also.
Initial data are delivered to scientists within 12 hours. Air samples are shipped to the University of Colorado's Institute for Arctic
We are showing the power of using dependable low-cost prop planes to make frequent repeat measurements over time to look for changes from month to month and year to year.
Ground observations complement the aircraft data and are used to calibrate and validate them. The ground sites serve as anchor points for CARVE's flight tracks.

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.

the third pattern corresponded to a poleward shift of the westerlies toward the South pole with a weakening in the maximum strength of the jet;
--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.
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.

The chemicals which are produced from sources such as planes factories and automobiles are converted to ozone in the presence of sunlight
whereas airplanes make up only one percent. They also found that nitrogen dioxide contributes about two-thirds of the ozone greenhouse gas effect compared to carbon monoxide and non-methane hydrocarbons.
The researchers measured the amount of biomass currently covering the study areas using the Carnegie Airborne Observatory (CAO)--an aircraft loaded with state-of-the-art imaging systems (funded by the Andrew Mellon Foundation.

We can think of it in terms of being on an aeroplane. The Earth is the plane and the species are the bolts holding the machine together.

#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.
The technology could also supply a source of renewable jet fuel required by recent European union aviation emission regulations.
Commercialization will lead to the widespread use of proprietary Vertimass technology for low cost production of sustainable transportation fuels for aircraft and heavy and light duty vehicles from multiple sources of biomass on a large scale.
