Mystery of the 100 'Missing Brains' Is Solved
Officials have found 100 brains that disappeared from a facility at the University of Texas in Austin in the 1990s.
It turns out the brains were at the University of Texas in San Antonio, Timothy Schallert, a professor of neuroscience and psychology at the Austin school, said Wednesday.
"They have the brains," he told the Los Angeles Times. "They read a media report of the missing brains and they called to say: 'We got those brains!'"
"I know the brains will be treated very well there," Schallert added.
In the 1990s, officials discovered that about half of 200 brains stored at the Austin school were missing. Most of the brains were from patients at a state mental hospital and were used for research.
The missing brains attracted widespread media attention this week after publication of a book called "Malformed: Forgotten Brains of the Texas State Mental Hospital."
"I didn't think this would get this much interest in the media," Schallert told the Times. "But thanks to media reports, we now know what happened."
Monitoring Ends for NYC Health Workers Exposed to Ebola Patient
Tuesday marked the end of the monitoring period for the last of the New York City health care workers exposed to a doctor with Ebola.
Dr. Craig Spencer spent nearly three weeks at Bellevue Hospital Center and was cared for by 114 doctors, nurses, paramedics and other health workers during that time. All of those workers were monitored for signs of the deadly virus for 21 days after their last contact with Spencer, The New York Times reported.
Spencer arrived at Bellevue on Oct. 23 after volunteering with Doctors Without Borders in Guinea. He was kept in isolation and received plasma from an Ebola survivor, an experimental drug and fluid maintenance.
After being found free of Ebola, Spencer returned to his Manhattan apartment on Nov. 11. He has been the only person treated for Ebola in New York City.
However, city health officials continue to monitor travelers for three weeks after they arrive from Ebola-affected countries in West Africa. As of Tuesday, 222 people were being monitored, The Times reported.
NBC's Dr. Nancy Snyderman Apologizes for Breaking Ebola Quarantine
The chief medical editor of NBC News has apologized for violating her voluntary Ebola self-quarantine.
Dr. Nancy Snyderman expressed her regrets during an interview on NBC's "Today" show on Wednesday.
"I'm very sorry for not only scaring my community and the country, but adding to the confusion of terms that I think came as fast and furious as the news about Ebola did," Snyderman said in her first appearance since she broke her self-imposed 21-day quarantine.
Snyderman traveled to Liberia in October to report on the Ebola outbreak. A photojournalist working with her team contracted the deadly virus, and Snyderman agreed to the voluntary self-isolation before she returned to the United States.
But after returning home, Snyderman and her crew were seen getting takeout food from a New Jersey restaurant, which led state officials to make her quarantine mandatory.
"I wear two hats -- I have my doctor hat and I have my journalist hat, and when the science and the messaging sometimes collide, and you leave the optics, in this case a hot zone and come back to the United States, good people can make mistakes," Snyderman said.
"I stepped outside the boundaries of what I promised to do and what the public expected of me, and for that I'm sorry," she added.
