As the violence unfolded between Russia and Georgia during the past week, hackers waged war on another front: the Internet.

The Georgian government accused Russia of engaging in cyberwarfare by disabling many government Web sites, making it difficult to inform citizens quickly of important updates. Russia said that it was not involved and that its own media and official Web sites had suffered similar attacks. Although a cease-fire has been ordered, major Georgian servers are still down, hindering communication in the country.

If you want to delay the consequence of aging, you’d better start running on daily basis according to a new study published in the August 11 issue of the journal Archives of Internal Medicine.

It has long been known that physical exercise improves our life, helping us maintaining a healthy heart and body. Previous research has also shown that exercise improves thinking and memory in people with normal brain activity. How is that possible? Well, the researchers believe that exercise increases blood flow to the brain, delivering oxygen and nutrients to brain cells, and elevates growth hormones. That’s exactly the reason for which exercising is recommended even in the case of people with Alzheimer’s.

Impeaching Musharraf

Pakistan's Parliament convened this week to initiate impeachment proceedings against President Pervez Musharraf. The same day, radical Islamists staged a rally in support of the move and a purported al Qaeda tape also surfaced, praising the idea. That shows what's at stake here: Pakistan's very existence, and its future as a moderate, democratic state.

This is a treacherous crossroads for Pakistan and for its main ally in the war on terror, the U.S. For all his missteps, President Musharraf has understood that fighting religious extremism is as crucial to Pakistan's sovereignty as it is to the free world's. Under his eight-year rule, he netted al Qaeda operatives, supported the breakup of the A.Q. Khan proliferation network, made peace with India, and committed blood and treasure to crack down on the Taliban in Pakistan's border regimes.

Aides to Republican Sen. John McCain were scrambling last Thursday morning even as his plane was descending into Des Moines. Russia had escalated its aggression in the bordering Republic of Georgia, they told reporters, and McCain wanted to seize the moment.

On the ground in Iowa, advance men raced to erect a podium on the tarmac, just feet from McCain's plane. The Republican nominee strode to the microphone for the first of several blistering statements condemning Russia's moves, delivering his comments well before President Bush spoke publicly about the incident.

The presidential campaign strategies these days are clear. For the Democrats, it's time to stop the bickering and rally round Barack Obama, who dominates the Democratic National Committee's Web site.

On the Republican National Committee site, it's all Obama, all the time, boosting the campaign's "celebrity" theme, which appears to be gaining some traction. Recent polls showed that the public is tiring of hearing about the once-new-and-fresh young Democratic candidate. At the same time, the GOP is pounding Obama as just Hollywood, an empty suit, no experience, and who is he anyway?

Sen. John McCain's top foreign policy adviser prepped his boss for an April 17 phone call with the president of Georgia and then helped the presumptive Republican presidential nominee prepare a strong statement of support for the fledgling republic.

The day of the call, a lobbying firm partly owned by the adviser, Randy Scheunemann, signed a $200,000 contract to continue providing strategic advice to the Georgian government in Washington.

BEIJING, Aug. 12 -- The pig-tailed girl in a red dress who sang "Ode to the Motherland" during Friday's Opening Ceremony for the Olympics was fit for the event, but apparently her voice was not.

A Chinese government official acknowledged Tuesday that the girl was actually lip-syncing at Beijing's "Bird's Nest" Stadium; the real singer's face was deemed "not suitable."

Traffic backed up at the Chesapeake Bay Bridge again this morning as authorities continued investigating a Sunday wreck that claimed the life of a truck driver whose tractor-trailer rig plunged through the side of the eastbound span and into the water.

The right lane of the bridge's eastbound span remained closed on Monday, although officials opened one of the three westbound lanes to traffic headed for the Eastern Shore.

It's been a wild week for Apple and its famous iPhone, as they got caught between a $1,000 application, rumors that Apple “takes care” of our iPhones even if we don't necessarily want them to and several apps being taken down from the App Store without explanation.

The result was: disoriented customers, disappointed developers and a lot of questions and theories about a “kill switch” that acts as a secret big red button that Apple might push anytime they find something they don't like on your iPhone.
