By Stratiev, Dicho Dinkov, Rosen; Kirilov, Kiril; Petkov, Krasimir An investigation of 28 crude samples from Russia, FSU countries, the Middle East, North Africa, and Bulgaria showed that the crude true boiling point (TBP), or ASTM D-86 distillation, density, and sulfur content, along with the Riazi's property distribution model and known correlations, can determine the physical and chemical properties of each 1% narrow cut of the crude. The samples have densities (d^sub 4^^sup 20^) of...

Hydrocarbons "“ molecules critical to life "“ are being generated by the simple interaction of seawater with the rocks under the Lost City hydrothermal vent field in the mid-Atlantic Ocean. Being able to produce building blocks of life makes Lost City-like vents even stronger contenders as places where life might have originated on Earth, according to Giora Proskurowski and Deborah Kelley, two authors of a paper in the Feb. 1 Science. Researchers have ruled out carbon from the...

Saturn's moon Titan is notorious for its shroud of organic haze. Recent experiments suggest that early Earth may have been covered by a similar haze. The discovery could shed light on how life spread around the globe. NASA - Saturn's giant moon Titan is enveloped by a thick layer of organic haze. Although Titan's haze layer is unique in the present-day solar system, a recent experiment by researchers at the University of Colorado at Boulder suggests that, billions of years ago, Earth was also...

Scientists knew Saturn's giant moon Titan would be interesting, perhaps containing organic compounds that are the building blocks of life. But the discovery of methane lakes and a "methanosphere" raises a question: is a frozen moon orbiting a giant gas planet Earth's closest analog in the solar system? NASA - Saturn's moon Titan seems to have little in common with Earth. At just 93 Kelvin, the giant moon is beyond ice cold, and its atmosphere is dominated by methane rather than nitrogen and...

SWRI -- Saturn's moon Titan has long been a place of interest to astrobiologists, primarily because of its apparent similarities to the early Earth at the time life first started. A thick atmosphere composed primarily of nitrogen and abundant organic molecules (the ingredients of life as we know it) are among the important similarities between these two otherwise dissimilar planetary bodies. Scientists have considered it very unlikely that Titan hosts life today, primarily because it is so...

On Earth, methane is mostly produced by life. The recent detection of methane on Mars therefore has led to much speculation about the possibility for life on the Red Planet. The strategies that may resolve this issue are revealed in the final part of this series on martian methane. Astrobiology Magazine -- Are microbes making the methane that's been found on Mars, or does the hydrocarbon gas come from geological processes? It's the question that everybody wants to answer, but nobody can....

A burst of high-frequency sound waves is enough to turn a range of oily liquid mixtures to jelly. Because the reaction is reversible, it could be used to remotely control the viscosity of liquid shock absorbers in cars or of lubricants in robotic joints, or to temporarily solidify fuels and paints so they don't leak during transport. Engineers may one day even use the technology to make building dampers that absorb energy from external forces, prolonging a structure's life and preventing a...

UPI -- During its closest flyby of Titan on April 16, NASA's Cassini spacecraft detected some surprisingly complex organic molecules floating in its upper atmosphere. Specifically, the spacecraft's mass spectrometer picked up the presence of a variety of hydrocarbons, including ethane and even octane. The giant moon Titan orbits Saturn some 800 million miles away from the sun. It is so cold -- hundreds of degrees below zero, both Fahrenheit and Celsius -- it might harbor dark seas of liquid...

JPL -- During its closest flyby of Saturn's moon Titan on April 16, the Cassini spacecraft came within 1,027 kilometers (638 miles) of the moon's surface and found that the outer layer of the thick, hazy atmosphere is brimming with complex hydrocarbons. Scientists believe that Titan's atmosphere may be a laboratory for studying the organic chemistry that preceded life and provided the building blocks for life on Earth.  The role of the upper atmosphere in this organic "factory" of...
