Topping tech headlines Tuesday was news that Google has added song lyrics to search results.


Users in the U.S. and Canada can now search for words to their favorite tunes without leaving Google's search results page. Type in "Stairway to Heaven lyrics," for example, and you'll be greeted with a verse from the song—about 120 to 150 words; the rest can be found via a link to Google Play, where you can buy a song with one click, or give it a listen (if it's already in your music library).


In other news, Mac users received Apple's first automated security update, which was released to defend against newly identified bugs that could allow hackers remote access. The flaws in OS X's network time protocol (NTP) were revealed last week. Apple has not been officially identified among the affected vendors, but Cupertino applied a "seamless" update, which the company said "doesn't even require a restart."


Meanwhile, the U.S. International Trade Commission (ITC) will investigate patent infringement claims made by Samsung against Nvidia and several other companies, including Android console maker Ouya. Samsung is claiming the manufacturers violated four of its patents related to graphics processing technology.
