The Cone Nebula
Friday, August 30, 2013: The Cone Nebula (NGC 2264) consists of a glowing cloud of ionized gas excited by the surrounding hot, massive young blue stars. Strong winds of particles blow from these stars, shaping the residual gas left from a spent star formation region, creating these structures with striking appearances.
"The Hubble Space Telescope has captured what scienitsts are describing as a "cosmic caterpillar" nearly 6 trillion miles long slinking through deepspace.
The celestial critter in the new Hubble telescope photo is actually a cloud of gas stretching one light-year (10 trillion kilometers) across, scientists say. This cloud is in the process of collapsing down under its own gravity to give birth to a star — but it’s a race against time, because the established bright stars in its vicinity are fighting this process.”
"Scientists from Conservation International have discovered a new species of shark living in the waters of Indonesia. Unlike other sharks, however, this species has an unusual way of getting around; it walks.
This ambulating aquatic creature uses its fins to gently glide across the sea floor on its belly as it searches for food and a place to rest. The newly discovered shark, called the epaulette shark (Hemiscyllium halmahera), is one of nine walking sharks found all over the world.”
"Raul Rabadan and collaborators are analyzing more than 60,000 viral sequences, searching for specific factors that make some viruses able to easily infect people. But the genome sequences in these databases can be of mixed quality, so researchers first had to come up with a way to glean only the most accurate and useful information, identifying likely sequencing errors or sources of contamination. “Some are sequences not correctly annotated, some are low-quality or incomplete, so we use only the ones we trust,” said Rabadan. “We have our own algorithms for trimming down to what we trust.” Without cleaning and curating the data, the signals picked up by machine learning algorithms could be associated with “weird stuff instead of biologically interesting things,” he said.”
A study of whooping cranes has shed new light on how much of a bird’s migration route is learnt, and how much is innate in its genetics.
"Scientists found that learning from older, more experienced birds was a crucial factor in the migratory habits of this long-lived, social species.
The US-German team of researchers also found that the cranes’ migratory performance improved over time.”
“Two University of Washington researchers say they have demonstrated that one man’s thoughts can control another man’s movements. First, they placed electronic probes against their heads. Then one man looked at a computer game on a screen and thought about what move he wanted to make. Sure enough, the other man, who was across campus with no view of the screen, almost instantaneously moved his right index finger to make that move. He said it had the sensation of a nervous tic.”
"Curiosity used its onboard camera, equipped with a telephoto lens, to capture Phobos’ passage past the sun. The image was captured on Aug. 17, which marked, according to NASA, the 369th sol, Martian solar day, of Curiosity’s mission on Mars."
"The mission is called Chang’e-3, and the official Chinese media is now reporting that it has completed its planning and construction phases. By the end of this year (if all goes well), the unmanned Chang’e-3 spacecraft will land a robotic rover on the Moon."
"The canyon - which is 800km long and up to 800m deep - was carved out by a great river more than four million years ago, before the ice arrived.
It was discovered by accident as scientists researching climate change mapped Greenland’s bedrock by radar.”
A new type of battery has been developed which its creators say could revolutionise the way we power consumer electronics and vehicles.
The University of Illinois team says its use of 3D-electrodes allows it to build “microbatteries” that are many times smaller than commercially available options, or the same size and many times more powerful.
It adds they can be recharged 1,000 times faster than competing tech.
However, safety issues still remain.
A new patent application from Google augments the company’s Glass head-mounted computer with a laser projector, which can be used to project an interface on any nearby surface, including the user’s own hand.
