The Moon and water!

NASA reveals that there is a significant amount of water on the Moon.

In a rather awful pun, NASA published update on the LCROSS Mission starts with the words, “The argument that the moon is a dry, desolate place no longer holds water.

Anyway, the significance of the update is enormous.  As the NASA release goes on to say,

Scientists have long speculated about the source of vast quantities of hydrogen that have been observed at the lunar poles. The LCROSS findings are shedding new light on the question of water, which could be more widespread and in greater quantity than previously suspected.

Permanently shadowed regions could hold a key to the history and evolution of the solar system, much as an ice core sample taken on Earth reveals ancient data. In addition, water, and other compounds represent potential resources that could sustain future lunar exploration.

The BBC also reports the NASA data but, I am bound to say, in a rather more reader-friendly format.

Reflecting on insider trading

Time to Reassess Insider Trading Rules?

On the face of it, prohibiting insider trading seems to be fair and reasonable.

US insider trading laws, refined over time in court on a case-by-case basis, define “trading on the basis of inside InsiderTradinginformation” as any time a person trades while aware of material nonpublic information (US Securities and Exchange Commissions Rule 10b5-1, which also creates an affirmative defense for pre-planned trades.) SEC regulation FD (“Fair Disclosure”) also requires that if a company intentionally discloses material non-public information to one person, it must simultaneously disclose that information to the public at large; in an unintentional disclosure, the company must make a public disclosure “promptly.” Lastly, the Williams Act gives the SEC regulatory authority over insider trading in takeovers and tender offers.
