A new heat­detecting camera can catch a liar(说谎的人)at least 75% of the time，according to a small scientific study out today.

“If more tests prove its ability，the lie­detector camera might one day be used by airports to catch terrorists(恐怖分子)before they get on an airplane”，says researcher James Levine of the Mayo Clinic.

But some people doubt whether the camera would ever be reliable enough to be used widely，or whether it could tell someone who plans to break the law.

Levine’s group reported their early findings in the journal Nature.

Levine and his colleagues asked 20 U．S.Army soldiers to help test the camera，which records the heat patterns when blood rushes to the human face.The researchers told eight of the soldiers in the study to kill a model man，rob it of 20 dollars，then lie about the “crime”．The remaining 12 people in the study knew nothing about the “crime”．

The researchers took all 20 people into a room.They asked them whether they had stolen 20 dollars and then recorded their answers with a standard polygraph test(标准测谎仪)and the new camera.

The camera caught six out of eight liars as they were lying-the same lie­detecting ability as the polygraph test.The camera also correctly identified 11 of the 12 people who were telling the truth-a slightly better rate than the polygraph.

“The study is so small that it can’t be used as proof of the camera’s ability to catch a thief or a liar”，Levine says.Still，he is hopeful that the camera is recording a flushing of the face that may occur when someone lies.

The flushing may not be caught by human eyes，but the camera shows a bright red­orange­yellow zone that represents blood rushing to the eyes.“When someone lies，you get a warming around the eyes，”he says.Levine speculates that people who lie are afraid of getting caught.That fear leads to an immediate response to run away.Blood goes to the eyes so that the liar can more easily find a way to escape.

Levine says it may take years before the camera would be ready for a test at a large

U．S.airport.

Alan Zelicoff，a senior scientist at the Center for National Security and Arms Control at the Sandia National Laboratories in Albuquerque，says that even if the camera works as well as it did in this study，it would mistakenly consider lots of people as liars.At a busy U．S.airport，those mistakes would mean a thousand passengers a day who would get pulled aside-a move that would probably mean lots of missed flights，he says.

APERSON 1.83 m in height would be thought tall in most company.But Chris Paul has to look up to nearly everyone in the NBA.

However，the 24­year­old is one of the best point guards(控球后卫)in the league(联盟)，despite the fact he’s shorter than most other players.He also won a gold medal while playing for the US team at the Beijing Olympics.Paul tells his story in his book，Long Shot：Never Too Small to Dream Big.

So what are the New Orleans Hornets star’s secrets to success?

Paul says we need to set goals(目标)．“Every year since I’ve been in the NBA I’ve set goals，”he said.“As a rookie(新秀)，it was to be Rookie of the Year，make the rookie All­Star game.Then be an All Star，be first­team NBA.I’ve done all that stuff.”

As he achieved each goal，he improved statistically(统计数据上地)-last season he averaged 22.8 points and 11 assists(助攻)．“Going into this season，my only goal is to win a championship，”he said.

The fact that Paul is a team player also explains his success.No one in the NBA improves his teammates，or is more interested in improving them，than Paul.He gets his teammates involved in the offense(进攻)，gets them shots，and lets them take the credit for winning.“This is a guy who could lead the team to score if he wanted to.That shows the contrast(对比)between him and a guy like Kobe Bryant.As Kobe’s teammate，you are a spectator(观众)．As Paul’s teammate，you become the show，” wrote Mike Moreau，a sports writer with the American magazine Hoopsworld.
