Damaging cyberattacks on a global scale continue to surface every day. Some nations are better prepared than others to deal with online threats from criminals, terrorists and rogue nations.

Data-mining experts from the University of Maryland and Virginia Tech recently co-authored a book that ranked the vulnerability of 44 nations to cyberattacks. Lead author V.S. Subrahmanian discussed this research on Wednesday, March 9 at a panel discussion hosted by the Foundation for Defense of Democracies in Washington, D.C.

The United States ranked 11th safest, while several Scandinavian countries (Denmark, Norway and Finland) ranked the safest. China, India, Russia, Saudi Arabia and South Korea ranked among the most vulnerable.

A substantial proportion of women in countries around the world do not stay in health facilities for long enough after giving birth, which could result in them receiving inadequate postnatal care, according to an analysis of survey results by the London School of Hygiene&Tropical Medicine, which compiled and analyzed information from databases and health surveys to look at the length of time women stay in health facilities after childbirth in 92 countries, and found wide variation.
