The cloning of a Dr. Hwang

By JOHN SCHWARTZ

Published: January 28, 2006

 

Dr. Hwang's new troubles were presaged earlier this week when Dr. Schatten, the senior co-author of the Science article, wrote to the journal asking that his name be withdrawn from the article and urging Dr. Hwang and the other co-authors to retract it. Dr. Schatten wrote that he had "substantial doubts about the paper's accuracy" and had heard that some of the experiments had been fabricated.

Although the new disclosures are being presented as a blow to Korean science, they can also be seen as a triumph for a cadre of well-trained young Koreans for whom it became almost a pastime to turn up one flaw after another in his work. All or almost all the criticisms that eventually brought him down were first posted on Web sites used by young Korean scientists, although vigorous reporting by MBC television and the online newspaper Pressian also played a leading role.

The young scientists were more skeptical of Dr. Hwang than was Dr. Schatten, who agreed to be senior co-author on Dr. Hwang's article this June in Science, even though all the experiments had been done in Seoul. The referees and editors at Science accepted the Schatten-Hwang article without spotting the problems that later came to light, although they did ask for extra tests that may have contributed to the denouement.

The debacle is particularly surprising to the many American scientists who visited Dr. Hwang's lab at the Seoul National University and were impressed by the dedication of his 65 colleagues, the specialization of his lab into separate units for each aspect of cloning, and the technical skill of those who worked the micromanipulators used to suck the nucleus out of human cells.

In what might resemble a horrifying moment in a science fiction film, astronauts aboard the International Space Station will toss an empty spacesuit overboard next week.

The Russian suit will carry three batteries and a ham radio transmitter and antenna. Amateur radio operators on Earth will be able to listen to its transmissions over several days until the batteries fail.

The space station has long had a bond with earthbound amateur radio operators, and there is a ham rig on the station to communicate with them. The idea of turning a suit into a satellite came from the Russians, NASA officials said.

In a few weeks, the orbit of the suit (designated SuitSat-1) will decay, and the suit will burn up as it falls into the atmosphere. Kwatsi Alibaruho, a NASA flight director who spoke yesterday at a news conference in Houston, said, "No part of the suit is expected to survive re-entry."

The suit will be released during a spacewalk on Feb. 3 in which the astronauts, William S. McArthur Jr. of the United States and Col. Valery I. Tokarev of the Russian Air Force, will also repair a moving platform that carries the station's robot arm.

In December, a safety device designed to cut snagged cables cut one of two control lines to the platform; NASA is studying why the accident occurred. The spacewalkers will install a bolt that will keep the second line from being cut until a more complete repair can be carried out.

"It's very important that we repair this," said Kirk Shireman, the deputy space station program manager.

Anyone with a ham radio or police scanner that picks up the FM frequency 145.990 MHz can listen to the spacesuit's transmissions. NASA has put a computer program online at http://science.nasa.gov/RealTime/JPass/25/JPass.asp to help people figure out when the suit will be traveling overhead.

The suit will be unpressurized, but the astronauts have stuffed it full of discarded clothing so that it should retain a somewhat human shape. Sensors will monitor the suit's temperature and battery power, which will be transmitted along with a message in five languages.

The message (which is not "heeeeeellllllppp!") will include an image and secret words for student listeners to decipher.
