Song Lyrics Now Available in Google Search Results
Google has added song lyrics to the ever increasing amount of information you can obtain using the search engine. Users will have easy access to the words of all of their favorite songs by simply typing the name of the song and the word lyrics after it. The full lyrics of the song won't be displayed and Google is encouraging users to continue to Google Play to get the full song and the addition of the lyrics is possibly a method of increasing traffic to and use of its music service. The new search results don't currently support all songs and lyrics websites shouldn't have to worry too much yet about being overtaken by Google.

New Model for Liquid Electrolytes
Without question, lithium-ion batteries are among the most important discoveries made in recent history, as they have enabled so much technology to go mobile. Like the devices they power, they must advance to keep up with our demands, but this is more easily said than done. Researchers at Berkeley Lab though have recently analyzed the electrolyte used in these batteries, and made an unexpected discovery.
The liquid electrolyte within lithium-ion batteries contains lithium-ions (hence the name) and how they move from one electrode to the other is very important. Part of this process involves the local structure of the ions, and many believe it is tetrahedral. Now the Berkeley researchers have put this to the test with the first X-ray absorption spectroscopy study on the liquid electrolyte. It has not been possible to test the model previously, but the researchers were able to do so by firing the electrolyte through a microjet system, into a vacuum chamber, and through an X-ray beam.
The results indicate that the ions do not have the predicted structure, which means the models being used to improve lithium-ion batteries may need some updating. As most work on improving the batteries focuses on other elements, better understanding of the liquid electrolyte could open up new possibilities.

World's Thinnest Image Sensor Developed
Cameras are just about everywhere today, in part because we can make them small enough to fit in many of our devices. Researchers at Rice University however have pushed things to a new level by creating an atomically thin CCD. The new device uses a 2D metal chalcogenide to create the sensor just a couple nanometers thick.
Thin films of metal chalcogenides have been investigated for some time, especially molybdenum disulfide for its light-detecting properties. The Rice researchers investigated copper indium selenide (CIS) as it shows even greater promise. Electrons dissipate more slowly in it, making it more efficient at detecting light. In fact it is 10 times more efficient than the best the researchers have seen before. To that end they built a prototype, three-pixel CCD that is just nine atoms thick, which is about two nanometers.
Traditional CCDs are rigid and much thicker, but a thin-film CCD, like a CIS-based sensor, would be obviously smaller, but also flexible and transparent, opening up possibilities for it. One of these possibilities would be bio-imaging devices and sensors that are curved to match the lens being used, offering real-time correction of aberrations.
