"The WHO, largely unchanged since its creation, is ill-equipped to deal with the disease threats that this new world creates...the recent Ebola outbreak is a case in point. Even the WHO's director-general, Margaret Chan, said her organisation was "overwhelmed" and admitted that a crisis on that ... Read More
Bacteria that feed on methane can control its concentration once it is released from the ocean floor. This can potentially stop the greenhouse gas from entering the atmosphere. But ocean currents can easily disturb dinner, according to new study in Nature Geoscience.
There is a large, and rel... Read More
