Scientists propose an enhanced new model of the source of a mysterious barrier to fusion known as the 'density limit'

Researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed a detailed model of the source of a puzzling limitation on fusion reactions. The findings, published this month in Physics of Plasmas, complete and confirm previous PPPL research and could lead to steps to overcome the barrier if the model proves consistent with experimental data. "We used to have correlation," said physicist David Gates, first author of the paper. "Now we believe we have causation."

The discovery of the molecule Si-C-Si in space

The space between stars is not empty—it contains a vast reservoir of diffuse material with about 5-10% of the total mass of our Milky Way galaxy. Most of the material is gas, but about 1% of this mass (quite a lot in astronomical terms) takes the form of tiny dust grains made predominantly of silicates (sand is also silicates), although grains can also be composed of carbon and other elements. The dust grains contain a large fraction of many important elements in the universe like silicon, carbon, and iron. They also play several crucially important roles. They are essential to the chemistry that takes place in the interstellar medium by providing gas molecules with a surface on which to react with other molecules. They absorb ultraviolet and optical light, re-emitting the energy as infrared light, and thus they both constrain what astronomers can see and control much of the energy balance in the interstellar medium. Not least, ! in the early stages of a star's evolution the dust can coagulate into large clumps—the first step towards forming planets.

Unexpectedly little black-hole monsters rapidly suck up surrounding matter

Using the Subaru Telescope, researchers at the Special Astrophysical Observatory in Russia and Kyoto University in Japan have found evidence that enigmatic objects in nearby galaxies - called ultra-luminous X-ray sources (ULXs) - exhibit strong outflows that are created as matter falls onto their black holes at unexpectedly high rates. The strong outflows suggest that the black holes in these ULXs must be much smaller than expected. Curiously, these objects appear to be "cousins" of SS 433, one of the most exotic objects in our own Milky Way Galaxy. The team's observations help shed light on the nature of ULXs, and impact our understanding of how supermassive black holes in galactic centers are formed and how matter rapidly falls onto those black holes.

Wind effect following team car can help time trial rider win Tour prologue

Will next Saturday's Tour de France prologue in Utrecht get the winner it deserves? New aerodynamic research at Eindhoven University of Technology (TU/e) shows that riders in a time trial can save vital seconds by riding closer to the following team car. Over a short distance like the prologue of the Tour de France, that can save as much as 6 seconds: enough to make the difference between winning and losing. On longer time trials and events like world championships, the effect can even add up to tens of seconds. Which is why aerodynamics professor Bert Blocken is advising the international cycling union UCI to change the rules and increase the minimum gap between riders and their team cars. "The present rules could lead to unfair advantage."

Team develops new method for rapid authentication of edible oils and screening of gutter oils

The Food Safety and Technology Research Centre under the Department of Applied Biology and Chemical Technology of The Hong Kong Polytechnic University (PolyU) has developed a new method for rapid authentication of edible oils and screening of gutter oils. Authentication of edible oils has been a long-term issue in food safety, and becomes particularly important with the emergence and widespread use of gutter oils in recent years. However, the conventional analytical approach for edible oils is not only labor intensive and time consuming, but also fails to provide a versatile solution for screening of gutter oils. By setting up a simple analytical protocol and a spectral library of edible oils, the new approach is able to determine the authenticity of a labeled edible oil sample and hence screened gutter oils within five minutes.

Study seeks connections between sleep and memory consolidation in the cortex

(Medical Xpress)—Neurologists have known that an intrinsic connection exists between the consolidation of memory and neural activity during sleep. Indeed, over the course of the last century, researchers have increasingly characterized sleep as a brain state optimizing memory consolidation; an earlier emphasis on rapid-eye-movement (REM) sleep has shifted in recent years toward the function of slow-wave sleep (SWS) as an active brain state—for instance, involving the transfer of long-term fear memory from the hippocampus into cortical structures.

New family of small RNAs boosts cell proliferation in cancer

Since their discovery in the 1950s, transfer RNAs (tRNAs) have been best known for their role in helping the cell make proteins from messenger RNA templates. However, recent studies have led to a previously-unsuspected concept that tRNAs are not always the end product; namely, they further serve as a source of small RNAs. Now researchers have discovered a new species of tRNA-derived small RNAs that are produced only in hormonally-driven breast and prostate cancers, and which contribute to cell proliferation. The results will be published online the week of June 29th in the Proceedings of the National Academy of Sciences (PNAS).
