Pollution levels in Beijing, China have reached record levels this week.
The government has issued a rare "orange" warning, telling people to stay indoors.
Experts say major pollution sources are the millions of cars in Beijing, the coal burned for fuel, and lack of regulation on factories.
The environmental group Greenpeace said more than 8,000 people in four Chinese cities died prematurely last year because of air pollution.
Meteorologists say a change in wind direction Wednesday will help the problem.
An Ohio hospital has created something it hopes will give more patients access to health care -- a portable doctor's office.
The 8 x 5 box called the Healthspot can be moved to different locations and features a screen where patients can Skype with a doctor.
It also has a built-in blood pressure machine and thermometer.
Patients who have tested the Healthspot stations say they're convenient because patients can use them around their schedule.
The first one officially opens in Cleveland in February.
