Fwd: biocircuits

'Researchers have made great progress in recent years in the design and creation of biological circuits -- systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such elements are combined. Scientists have now come up with a way of greatly reducing that unpredictability, introducing a device that could ultimately allow such circuits to behave nearly as predictably as their electronic counterparts.'

Fwd: cool

'Physicists have developed a new cooling technique for mechanical quantum systems. Using an ultracold atomic gas, the vibrations of a membrane were cooled down to less than 1 degree above absolute zero. This technique may enable novel studies of quantum physics and precision measurement devices.'

Fwd: Rosetta


'The probe that landed on the surface of a comet has discovered organic molecules, the most rudimentary building blocks of life, according to the German agency involved in the mission.

 

An instrument aboard the Philae lander detected the molecules after "sniffing" the comet's atmosphere. An organic compound is one whose molecules contain the carbon atom, the basis of life on earth.

 

Scientists are analyzing the data to see whether the organic compounds detected by Philae are simple ones—such as methane and methanol—or a more complex species such as amino acids, the building blocks for proteins. A drill on Philae also obtained some material from the comet's hard surface, but data about organic molecules from that experiment have yet to be fully analyzed.'

Fwd: Science

'Engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for applications such as sensors for environmental and medical monitoring.'

'Physicists have engineered a spiral laser beam and used it to create a whirlpool of hybrid light-matter particles called polaritons, hybrid particles that have properties of both matter and light and could link electronics with photonics.'

'Engineers have successfully printed complex electronic circuits using a common t-shirt printer. The electronic circuits are printed using unique materials in layers on top of everyday flexible materials such as plastic, aluminum foil and even paper. Resistors, transistors and capacitors, the key components of a complex electronic circuit, are printed using non-toxic organic materials like silver nanoparticles, carbon and plastics.'

Re: Fusion


... This is extraordinary good news.  It means that the multi billion dollar French experimental reactor could be obsolete before it even starts.

Fwd: Binary starts


'Ghez, who studies thousands of stars in the neighbourhood of the supermassive black hole, said G2 appears to be just one of an emerging class of stars near the black hole that are created because the black hole's powerful gravity drives binary stars to merge into one.

 

Ghez also noted that, in our galaxy, massive stars primarily come in pairs. '
