<jats:p>Pinched by shrinking budgets, institutions of higher education, state legislatures, and boards of regents are reevaluating the terms of tenure, which has come under fierce attack in recent years. While a few institutions have abolished their tenure systems, most are tightening it up to ensure greater accountability. On many campuses, tenure is become harder to get and--with new systems of posttenure review--a little easier to lose.

<jats:p>To hear some critics tell it, tenure has gone the way of the one-room schoolhouse. But a closer look at Evergreen State College in Olympia, Washington, which often is cited as having spurned tenure, suggests that reports of the system's demise are premature.</jats:p>

<jats:p>Scientists who review grant proposals for the National Science Foundation (NSF) soon will be asked to judge them according to just two criteria: scientific quality and impact on society. The new approach, adopted last week by the National Science Board, eliminates separate criteria relating to the applicant's track record and the effect of the project on the nation's scientific infrastructure.</jats:p>

<jats:p>The National Cancer Institute (NCI) recommended last week that women in their forties should get mammograms every 1 to 2 years.

Now a third, far less expensive, idea has come to the fore--reviving a mothballed reactor at the Pacific Northwest National Laboratory in Washington state. </jats:p>
