Within 10 days of Miguel Diaz-Canel's big promotion to vice president of Cuba in February, he was already being tapped as a stand-in for reticent, 81-year-old President Raul Castro. It was Diaz-Canel, not Raul or Fidel Castro, who gave Cuba's first public condolences when the communist government lost its best friend and benefactor, Venezuelan President Hugo Chavez.
Try to put him in a box and he'll find his way out. Still working at nearly 85 years old, William Klein has gone rogue in at least four different fields: abstract painting, photography, filmmaking and commercial copy writing.
Klein now lives in Paris but I caught up with him in New York City — the place where he was born, but no longer has much affinity for. He's just here to promote a new book, William Klein ABC.
When I ask him what he thinks about the city, he says:
President Obama has announced an ambitious plan to explore the mysteries of the human brain.
In a speech Tuesday, Obama said he will ask Congress for $100 million in 2014 to "better understand how we think and how we learn and how we remember." Other goals include finding new treatments for Alzheimer's disease, epilepsy and traumatic brain injury.
Polio is on the verge of being eliminated. Last year there were just over 200 cases of polio, and they occurred in just two remote parts of the world — northern Nigeria and the rugged Afghan-Pakistan border region.
A new $5.5 billion plan being pushed by the World Health Organization strives to eliminate polio entirely, phase out vaccination campaigns and secure polio vaccine stockpiles in case the virus somehow manages to re-emerge.
If the effort is successful, polio would be just the second disease in human history, after smallpox, to be eliminated by medical science.
More than 1 million people are dying prematurely every year from air pollution in China, according to a new analysis.
"This is the highest toll in the world and it really reflects the very high levels of air pollution that exist in China today," says Robert O'Keefe of the Health Effects Institute in Boston, who presented the findings in Beijing this week.
