4:44 p.m. ET: It's unlikely that singer Sheryl Crow's meningioma - a tumor that occurs outside of the brain - triggered her memory loss, a doctor said today.
Dr. Michael Schulder, vice chairman of the department of neurosurgery at the Cushing Neuroscience Institute in New York, told ABC News today that Crow's commonly used treatment plan - a series of MRI scans to follow the tumor's growth - "suggests that it's not a very large tumor."
"The kind of symptoms she's describing [memory loss] that came and went. … It seems unlikely they are the result of tumors unless she had a small seizure" that she was unaware of, Schulder said.
3:15 p.m. ET: TONIGHT: "Nightline" investigates the Air France Flight 447 crash.
The Airbus A330 has one of the most sophisticated automated piloting systems in the airline industry, but the 2009 crash of Air France Flight 447 has some experts saying that the pilots weren't adequately trained to handle the plane in an emergency situation, and that the plane's stall alarm system may have added to the crew's confusion and contributed to the disaster.
The crash, which killed all 228 passengers and crew on board, is considered one of the worst - and most mysterious - aviation disasters in modern history. One theory for what caused that Airbus A330 to go down is that the two co-pilots, led by 58-year-old Captain Marc Dubois, were not properly trained and depended too heavily on the plane's autopilot system. That system disconnected at high-altitude when a speed sensor, called a pitot tube, froze over, sending inconsistent readings to the plane's computers.
2:04 p.m. ET: Death by volcano?
Super-volcanoes have probably caused more extinctions than asteroids. But until now it has been thought that these giant volcanoes took thousands of years to form - and would remain trapped beneath the earth's crust for thousands more years - before having much effect on the planet.
But new research indicates catastrophic eruptions, possibly thousands of times more powerful than the 1980 eruption of Mount St. Helens, may happen only a few hundred years after the super-volcanoes form. In other words, they may have a very "short fuse," according to researchers at Vanderbilt University.

9:35 a.m. ET: ABC's Jim Avila reports on a new government report obtained exclusively by ABC News.
An investigation by the Department of Health and Human Services' Office of the Inspector General (HHS OIG) found that many providers of immunizations meant for low-income children don't store the vaccines at proper temperatures, potentially rendering them ineffective and placing children at risk for contracting serious diseases.
