SAN FRANCISCO, March 23, 2010 — Scientists today described development of a new method to determine the age of ancient mummies, old artwork, and other relics without causing damage to these treasures of global cultural heritage.
Reporting at the 239th National Meeting of the American Chemical Society (ACS), they said it could allow scientific analysis of hundreds of artifacts that until now were off limits because museums and private collectors did not want the objects damaged.
Conventional carbon dating estimates the age of an artifact based on its content of carbon-14 (C-14), a naturally occurring, radioactive form of carbon.
THIS SCORECARD WAS LAST UPDATED IN SEPTEMBER 2007 AND IS NO LONGER BEING UPDATED. Note: This list contains companies that have disclosed government probes, misdated options, restatements and/or executive departures as of Septmeber 2007.In prior posts, I have discussed how conflicts of interest in management-led buyouts can give rise to litigation (refer here), and I have examined the ways the recent credit market turmoil is not only undermining leveraged buyouts but also engendering lawsuits (refer here).I have also extensively reviewed options backdating litigation (most recently here).In 2006, the Securities and Exchange Commission (SEC) notified ACS that they were conducting an informal investigation into certain stock option grants made by the company from October 1998 through March 2005.
This was due to the improper and unethical practice of back-dating stock options to specific low points in the stock value.
In February 2010, following its acquisition by Xerox, ACS was replaced by Urban Outfitters on the Standard & Poor 500 Index.
