Naked mole rats are becoming more popular in research laboratories, The rodents have surprised scientists with their ability to live up to 30 years and their potential to offer insights into human health.
Lists of the world's ugliest animals sometimes include the naked mole rat. But scientists who have just analyzed its entire genetic code say this bizarre little creature has an inner beauty — unique traits that could aid research on cancer and aging.

In recent months, local residents say Islamists have attacked and damaged this shrine in Sheikh Zuweid in northern Sinai. Egyptian and Western officials have raised concerns about Islamist groups springing up in North Sinai, but the locals say they wield no power here.

Ayman al-Zawahiri (shown here in a still image posted online by al-Qaida in July) replaced Osama bin Laden at the top of al-Qaida's leadership. Some argue that eliminating a few key leaders would significantly weaken the group; others say the more dangerous threat — from al-Qaida affiliates — would be unaffected by changes in the group's core leadership.
A debate is raging in the intelligence community about what it means to defeat al-Qaida. Because America's efforts to capture or kill al-Qaida's key members have been so effective, some officials say the core group — al-Qaida's founders and longtime members hiding out in Pakistan — is near collapse.
One camp, which includes members of the Obama administration, says al-Qaida's core group is three to five members away from collapse. Others, however, say with al-Qaida affiliates gathering strength, any victory over the core will be a hollow one.
