[Q]: We're not bluffing, the Obama administration told Afghanistan on Tuesday in announcing for the first time it has started planning for the possible withdrawal of all U.S. troops by the end of the year if no security agreement is signed. Statements by the White House and Defense Secretary Chuck Hagel showed President Barack Obama's impatience with Afghanistan President Hamid Karzai's refusal to sign the agreement that would keep several thousand American troops in the country after combat operations conclude this year. In a phone call with Karzai on Tuesday to discuss upcoming elections for a new Afghan leader, Obama made clear that time was running out to properly plan for keeping any U.S. forces in the country beyond 2014, the White House said.President Obama calls Afghan leader to discuss security agreementObama orders planning for bringing home all U.S. troops at the end of 2014Afghan President Karzai refuses to sign a deal to keep some troops thereThe White House says an agreement could happen after Karzai leaves office in April

[Q]: Under the Federal Government's recently announced budget, changes to the way women are screened for cervical cancer could spell the end of pap smears in Australia and a decrease in diagnosis. Under the previous healthcare system, women between 25 and 74 were encouraged to undergo an often-dreaded pap smear every two years - but under the new budget, a HPV screening test is set to replace it and would only be required every five years.
