Astronomers find new planet

LOS ANGELES — A new planet was discovered orbiting a sun-like star 41 light years away, making it the first known planetary quintet outside our solar system, astronomers said
Tuesday.
The newfound planet joins four others circling the nearby star 55 Cancri in the constellation Cancer. Although it resides in the star's so-called
Ranked fourth from 55 Cancri, the latest planet is about 45 times the mass of earth and has an orbit of 260 days. It was detected after nearly

Still, scientists have not ruled out finding an Earth-like planet within the system as technology improves.

tem were discovered between 1996 and 2004. The innermost planet is believed to resemble Neptune, while the most distant is thought to be lupiter-like.
Scientists have detected about 250 exoplanets, or planets orbiting a star other than the sun. The
55 Cancri star holds the record for number of confirmed planets. Only one other star is known to have four planets, while several others have three or less.
"We can now say there are stars like the sun that have many worlds around them," said planetary scientist Jonathan Lunine of the University of Arizona, Tucson, who had no role in the discovery.
The research will appear in a future issue of the Astrophysical Journal. It was funded by NASA, the National Science Foundation and the University of California.
The latest discovery shows that our solar system is not unique, scientists said.
"When you look up into the night sky and see the twinkling lights of stars, you can imagine with certainty that they have their own complement of planets," said astronomer Geoff Marcy of the University of California, Berkeley, who was part of the research.
Social site tips advertisers
FACEBOOK

NEW YORK — The online hangout Facebook said Tuesday it planned to help companies target their advertisements on the site based on what its users and their friends bought and did on the Internet.
As Web companies look to boost advertising revenue by offering to target ads to their users' hobbies, interests and behavior, Facebook's move could change the tone of the site and revive privacy complaints it faced last year.
Facebook Chief Executive Mark Zuckerberg, who founded the company three years ago, said marketers must respond to the changing nature of communication, driven in part by social-networking sites like his.
Facebook will now allow companies to build profile pages similar to the ones millions of users around the world now maintain. Companies also can now embed coding that Facebook calls Beacon on outside sites such as eBay Inc,
"Pushing your message out to people is no longer good enough," Zuckerberg told about 200 advertising-industry executives. "You have to get your message out to the conversations."
enabling a Facebook user who lists an item for auction, for example, to generate alert messages for their Facebook friends, who may then check out the item next time they log on.
Users can now send alerts to friends about their reviews of restaurants, what band they enjoyed and what books or DVDs they bought online. And advertisers can have their pitches appear next to those alert
the best way to profit from the trove of personal data their users put on profile pages.

"People influence people," Zuckerberg said. "Nothing influences a person more than a recommendation from a trusted friend."
The new program also enables advertisers to fine-tune their audiences — having their pitches appear only to women under 30 who attended New York University and work at Goldman Sachs, for instance.
Self-service tools let advertisers immediately see how many users they will reach as they change their criteria. Social-networking sites like Facebook and News Corp's MySpace have been trying to find
categories and more advertisers.
Privacy advocates say the key to user acceptance will be how Facebook notifies it, users and what controls it offers them.
Zuckerberg offered few details in the speech, but said no personally identifiable information would be shared with advertisers.
Facebook has long prided itself on privacy, but the site relaxed eligibility requirements and started letting nonusers search for members' personal profile pages at Facebook and through search engines like Google. A feature allowing users to more easily track changes their friends made backfired when many users denounced it as stalking and threatened protests and boycotts. Facebook had to quickly apologize and let users turn off the feature.

Men use cookies after drug burn

Madison County prosecutors on Monday charged Rosario James, 23, and Jordan Sallis, 20, each with two counts of aggravated kidnaping and one count of robbery and aggravated battery.
EDWARDSVILLE, Ill. — Two students in at Southern Illinois University in this St. Louis suburb kidnapped, paddled and burned a young man with freshly baked cookies after a drug deal went bad, prosecutors said.
Both were jailed Tuesday on $150,000 apiece.
Sheriff's Capt. Brad Wells said that Friday night, three men went
to James' house to buy marijuana, but two of them grabbed the drugs and fled, leaving the third behind. The suspects held that man, who is in his late teens, and told him he needed to find $400 for the drugs, Wells said.
The suspect bets the man with a wooden paddle, burned his neck and shoulders with cookies immediately after taking them from the oven, shaved off some of his hair and poured urine over him from a soda bottle. Wells said.
"It was just sheer torture," Wells said.
Hours later, Wells said, the victim managed to escape and call police after the suspects drove him
The victim sustained severe bruising but was not hospitalized.
to a house in trying to get money for the drugs.
Both suspects were arrested Saturday morning.
There was no evidence that James or Sallis had been using drugs before or during the alleged torture, Wells said Tuesday.
"Basically they ripped them off of their drugs, and they took exception to that." Wells said.
There was no record that James or Sallis had obtained an attorney as of Tuesday, a Madison County court clerk said.
