An anonymous reader writes A research team from the University of California, Riverside and Montclair State University, New Jersey, have found that the lack of teeth in all living birds can be traced back to a common ancestor who lived about 116 million years ago. From the article: "To solve this puzzle, the researchers used a recently created genome database that catalogues the genetic history of nearly all living bird orders--48 species in total. They were looking for two specific types of genes: one responsible for dentin, the substance that (mostly) makes up teeth, and another for the enamel that protects them. Upon finding these genes, researchers then located the mutations that deactivate them, and combed the fossil record to figure out when those mutations developed. They concluded that the loss of teeth and the development of the beak was a two-stage process, though the steps basically happened simultaneously. The paper states: 'In the first stage, tooth loss and partial beak development began on the anterior portion of both the upper and lower jaws. The second stage involved concurrent progression of tooth loss and beak development from the anterior portion of both jaws to the back of the rostrum.'"Read Replies (0)

The Associated Press, as carried by ABC News, reports that "An 11-judge panel of the 9th U.S. Circuit Court of Appeals in Pasadena will hear arguments Monday by Google, which owns YouTube, disputing the court's decision to remove Innocence of Muslims
from the popular video sharing service." At the heart of the earlier take-down order, which was the result of a 2-1 split from a 3-judge panel, is the assertion of copyright by actress Cindy Lee Garcia, who appeared in the film, but in a role considerably different from the one she thought she was playing.Google is supported in its appeal by an unusual alliance that includes filmmakers, Internet rivals such as Yahoo and prominent news media companies such as The New York Times that don't want the court to infringe on First Amendment rights. Garcia has support from the Screen Actors Guild and the American Federation of Musicians. If the court upholds the smaller panel's ruling, YouTube and other Internet companies could face takedown notices from others in minor video roles.Read Replies (0)

An anonymous reader send this link to a developing situation in Sydney, Australia, being reported on via live feed at the Guardian
, and covered by various other news outlets as well. According to CNN's coverage, "CNN affiliate Seven Network said that at least 13 people are being held at the Lindt Chocolate Cafe

From The New York Times' coverage
: The police have shut down parts of the city’s transport system, and closed off the mall area. They would not confirm how many people were being held hostage inside the cafe, nor whether those inside are armed.
Local media reports said that the airspace over Sydney had been closed and the famed Sydney Opera House evacuated. Television images showed heavily armed officers with their weapons trained on the cafe.Read Replies (0)

English-language site The Spain Report reports that Google's response to mandated payments for linking to and excerpting from Spanish news media sources — namely, shutting down Google News in Spain — doesn't sit well with Spanish Newspaper Publishers' Association
, whichissued a statement [Thursday] night saying that Google News was "not just the closure of another service given its dominant market position," recognising that Google's decision "will undoubtedly have a negative impact on citizens and Spanish businesses. Given the dominant position of Google (which in Spain controls almost all of the searches in the market and is an authentic gateway to the Internet), AEDE requires the intervention of Spanish and community authorities, and competition authorities, to effectively protect the rights of citizens and companies."
Irene Lanzaco, a spokeswoman for AEDE, told The Spain Report by telephone that "we're not asking Google to take a step backwards, we've always been open to negotiations with Google" but, she said: "Google has not taken a neutral stance. Of course they are free to close their business, but one thing is the closure of Google News and quite another the positioning in the general index."
Asked if the newspaper publishers' association had received any complaints from its members since Wednesday's announcement by Google, Mrs. Lanzaco refused to specify, but said: "Spanish publishers talk to AEDE constantly."Read Replies (0)
