The two United States aid workers who were the first patients ever to be treated for the Ebola virus at a hospital in the US have been released, capping a transcontinental medical drama that stirred public debate about whether citizens with the virus or exposed to the virus should have been allowed to return.
Scientists have created a new sponge-type material that absorbs carbon dioxide, which is believed to play a key role in global warming. The polymer – a large molecule used in plastics – is thought to have the potential to bridge the gap between the use of fossil fuels and new energy sources such as hydrogen, and could be integrated into power plant smokestacks in the future.

The World Health Organization reiterated its position that the risk of transmission of Ebola virus disease during air travel remains low. “Unlike infections such as influenza or tuberculosis, Ebola is not airborne,” says Dr Isabelle Nuttall, Director of WHO Global Capacity Alert and Response. “It can only be transmitted by direct contact with the body fluids of a person who is sick with the disease.”

A new study has found that every step counts – literally – towards reducing the risk of cardiovascular disease. Heart healthy exercise, moreover, need not be either time-consuming or tiring. Scientists at Iowa State University found that running for just seven minutes daily, even at slow speeds, could help reduce the risk of dying from heart disease by up to 50%.
In what is being viewed as one of the most important discoveries in the battle against cancer, a major review of trials and studies has revealed that long-term use of low-dose aspirin reduces the risk of developing major cancers and dying from them by around one-third.
