Urban Rainforest
On the west side of the island of Manhattan in New Y0rk City，tree by tree，leaf by leaf， a 2，500 square foot sector of the Central African Republic's Dzanga Ndoki Rainforest has been transported to，or recreated at，the American Museum of Natural History's new hall of biodiversity.When the hall opens this May， visitors will visit one of the world's biggest and most accurate reproduction of one of nature's most threatened creations.
To bring the rainforest to New Y0rk.a team of nearly two dozen scientists—the largest collecting expedition the museum has ever organised for an exhibit — spent five weeks in the African rainforest collecting soil，plants，and leaves；recording and documenting species；studying trees；shooting videotape and still photos；and interviewing local people.“This area has been explored very little，” says Hoel Cracraft who estimates that the museum will eventually collect 150 to 180 mammals，more than 300 species of birds，hundreds of butterflies，and hundreds of thousands，if not 111illions，of organisms.The exhibition may even have produced a special prize - scientists suspect they have uncovered several new species.
To give the forest a sense of realness，the back wall of the exhibit is an enormous videoscreen，sounds will come out from hidden speakers.and plans even call for forest smells.Computer controls will vary the effects so that no two walkthroughs will ever be exactly the same.
After the team returned to New York.the forest was reproduced with the help of the computer Computer modelling programmes plotted distances and special relationships.Artists studied photos and brought what they saw to 1ife.Plaster trees were made.Recreated animals began to stand in the rainforest of the hall.Flying creatures will hang from the ceiling.The 1ight in the forest—one of the exhibit's cleverest re-creations—will seem real.Long tube 1ights will have the correct colour and temperature to produce a natural effect.The plants and animals exhibited throughout the hall exist naturally in a perfect balance—remove one.and the whole is imperfect if not endangered.The exhibit is proof to the hope that the world's rainforests will never exist solely as a carefully preserved artifact.

Credit Card Only Works When Spoken to
A credit card that will not work unless it hears its owner's voice could become an important Weapon in the fight against fraud.
The card requires users to give a spoken password that it recognizes using a built-in voice—recognition chip.The idea is to prevent thieves using a stolen card or fraudsters using someone else's credit card details to buy goods online.。
A prototype built by engineers at Beepcard in Santa Monica，California，represents the first attempt to pack a microphone，a loud speaker， a battery and a voice-recognition chip into a standard.sized credit card.
They are not quite there yet：the card is the length and width of an ordinary credit card，but it is still about three times as thick.Alan Sege，Beepcard's CEO，says the company now plans to use smaller chips to slim it down to normal thickness.
The voice card is based Oil an earlier Beepcard technology designed to prevent fraud in online transactions.This earlier card has no microphone.but has a built.in loudspeaker that it uses to “squawk” an acoustic ID signal via a computer's microphone to an online server.
By verifying that the signal matches the card details，the server can establish that the user is not simply keying in…a credit card number but actually has the card to hand.The ID code changes each time the card is used in a pre-ordered sequence that only the server knows.
This prevents fraudsters recording the beeps.noting the card details and then playing back the audible ID when they key in the details later.But this earlier technology cannot prevent fraudulent use of stolen cards.The new one can.
The new voice card also identifies itself by-its ID squawk、but it will not do this until it has verified the legitimate user's spoken password.Thieves will be unable to use the card because even if they knew the password they would have to be able to copy the owner's voice with a high degree of accuracy.
The challenge for Beepcard has been to develop voice—recognition and audio circuitry that can be powered by a mini battery embedded in a credit card.To maximize battery life，the electronics are only switched on when the card is being used.Pressing a button on the card's surface prompts it to utter “Say your password” in female voice.If the voice-recognition software proves that the password is authentic， it sends its ID squawk which the server then identifies，allowing the transaction to proceed.
