Ebola outbreak could be worse than thought

The worst outbreak of the deadly Ebola virus in history could actually be much worse than the official death toll reflects. Already, the World Health Organization says 887 people have died, but as CBS News' Debora Patta reports, a top doctor working at the heart of the outbreak in West Africa says many cases are going unreported.

On the front lines of Ebola

A Boston doctor is headed to the front lines of the Ebola epidemic in Sierra Leone, and she says it's like going to battle. She'll be providing expertise on controlling the spread of the disease and personally treating those suffering from it.

Mideast Violence

A cease-fire between Israel and Hamas meant to last at least three days and end nearly a month of fighting went into effect in the Gaza Strip Tuesday -- and appears to be holding.

An Israeli delegation will head to Egypt for three days of talks meant to work out a long-term truce.

US-Israel relations amid the violence

The relationship between the U.S. and Israel has been strained as the death toll has mounted in Gaza, and there is growing U.S. discomfort about how the weapons it provides are being used. There has been simmering tension between the two countries since the U.S. blamed Israel for the collapse of peace talks in April.

Emerging genocide?

Attacks in Syria and Iraq may be an emerging genocide. Islamic militants known as ISIS stormed more towns in northern Iraq and graphic videos show ISIS fighters executing Shiite men in mass graves.

Last chance challenge

Grassroots conservatives entered 2014 hoping establishment Senate Republicans seeking re-election would be vulnerable to primary challenges. But in every instance, they've failed - in some cases, miserably. So far, they've lost every one of their intra-party Senate challenges. This week's primaries offer the grassroots conservatives a last gasp at ousting some incumbents.

Boring bonds

When stocks are getting battered by volatility and uncertainty as they did last week, the right allocation to high quality bond funds are a key part of a balanced portfolio. The brilliance of boring, high-quality bonds shines at key times.

Road work ahead

Consumers may see a pluses for driverless cars, believing self-driving cars would lead to fewer crashes on the road and better gas mileage. Experts believe there is still a lot of work to do concerning system failures in the technology and how the vehicles would mix with conventional ones.

The danger of artificial intelligence

With artificial intelligence honed to the point that robotic cars may drive better than those with humans behind the wheel, and that a computer has been crowned a "Jeopardy" champion, are mere biological brains in danger of becoming obsolete? One leading scientific mind says we need to stop and think before this technology gets out of control.

Change in law linked to more unsafe drugs, study finds

A law designed to accelerate the FDA's drug approval process may have backfired when it comes to safety. A growing number of FDA-approved prescription drugs receive black-box warnings for potentially lethal side effects or are later withdrawn from the market because of safety concerns.

Rosetta space probe closes in on comet

After a 10-year odyssey highlighted by four velocity-boosting planetary flybys, two asteroid encounters and two-and-a-half years spent in electronic hibernation, Europe's $1.7 billion Rosetta spacecraft finally reaches its target Wednesday, matching orbits with an oddball comet and dropping a small lander to its surface later this fall.
