wedish flame

This is called a Swedish flame. Make your cuts like you're cutting cake. Leave about 6 inches at the base. Throw some fuel oil in there (about a cap full). It burns up to two to three hours.

Atomically Thin Material Opens Door for Integrated Nanophotonic Circuits

A new combination of materials can efficiently guide electricity and light along the same tiny wire, a finding that could be a step towards building computer chips capable of transporting digital information at the speed of light.
Reporting today in The Optical Society's (OSA) high-impact journalOptica, optical and material scientists at the University of Rochester and Swiss Federal Institute of Technology in Zurich describe a basic model circuit consisting of a silver nanowire and a single-layer flake of molybendum disulfide (MoS2).
Using a laser to excite electromagnetic waves called plasmons at the surface of the wire, the researchers found that the MoS2 flake at the far end of the wire generated strong light emission. Going in the other direction, as the excited electrons relaxed, they were collected by the wire and converted back into plasmons, which emitted light of the same wavelength.
"We have found that there is pronounced nanoscale light-matter interaction between plasmons and atomically thin material that can be exploited for nanophotonic integrated circuits," said Nick Vamivakas, assistant professor of quantum optics and quantum physics at the University of Rochester and senior author of the paper.

Scientist Name, Map our Galactic Supercluster

University of Hawaii at Manoa astronomer R. Brent Tully, who recently shared the 2014 Gruber Cosmology Prize and the 2014 Victor Ambartsumian International Prize, has led an international team of astronomers in defining the contours of the immense supercluster of galaxies containing our own Milky Way. They have named the supercluster “Laniakea,” meaning “immense heaven” in Hawaiian. The paper explaining this work is the cover story of the September 4 issue of the prestigious journal Nature.
Galaxies are not distributed randomly throughout the universe. Instead, they are found in groups, like our own Local Group, that contain dozens of galaxies, and in massive clusters containing hundreds of galaxies, all interconnected in a web of filaments in which galaxies are strung like pearls. Where these filaments intersect, we find huge structures, called “superclusters.” These structures are interconnected, but they have poorly defined boundaries.

1) First Insert the Pen Drive atleast having an memory of 1GB ,( Preferably 4GB) in the Given USB port of the Computer

2) Wait for the Pen Drive Detection and see whether it is detected or not

3) After detection of Pen Drive, you should do the following things Carefully

4) Now go to My Computer and right click it, then go to the Properties

5) Now go to Advanced and then to the Performance settings

6) Now again Advanced, and go to Change

7) In the Change, select the pen drive which u inserted

Then click on the Custom size and " check the value of space available "

9) Please Enter the Same in the Initial and Maximum Columns also

10) Now your Pen drive space is used for the System Virtual Memory , Just Restart and enjoy the Faster and Furious PC —

Bacterial meningitis

Brain surrounded by pus (the yellow-greyish coat around the brain, under the dura lifted by the forceps), the result of bacterial meningitis. A brain autopsy demonstrating signs of meningitis. The forceps (center) are retracting the dura mater (white). Underneath the dura mater are the leptomeninges, which appear to be edematous and have multiple small hemorrhagic foci(red).

Disc of Destiny:

Disc of Destiny: New optical techniques could preserve data for millennia.

Messages are stored as two types of alterations in the way quartz glass refracts light. The combination of the two allows for data-storage densities as high as 360 terabytes per disc, or more than 7000 times today’s 50-gigabyte double-layer Blu-ray capacity.

Meet the Triquad!

As cool as quadrotors are, in most cases they're simply not as good as helicopters. So researchers came up with a "Y4" configuration that aims to take all the good bits of helicopters and make them as simple as quadrotors. Keep in mind that this is still a quadrotor: it just had things shifted around a little bit.

Flexible Battery Made From Nanotubes

Samsung may be releasing a semi-flexible phone, but researchers have developed a flexible battery made from carbon nanotubes. It's aimed at powering future flexible devices. Using standard electrochemical processes, carbon nanotube-enabled flexible battery can be made to any size.

NEC debutes adorable companion robot

The new robot, Papero Petit, stands 24 centimeters (9.4 inches) tall and weighs 1.3 kg (2.8 lbs)—about half the size of earlier models. It combines multiple sensors (cameras, ultrasonic range finders, temperature sensor, and microphones) to detect people and look in their direction even in complete darkness. The robot can recognize faces and has between 80 to 90 percent success rate at speech recognition.
