The mysterious disease that killed 14 people in Uganda since the beginning of July 2012 has finally been identified as the Ebola virus. The Ministry of Health (MoH) of Uganda and a World Health Organisation (WHO) representative reported the news after laboratory confirmation was done by the Uganda Virus Research Institute in Entebbe. A total of 20 total cases have been confirmed in Kibaale district, in the western part of Uganda, nine of which have occurred in a single household. Ebola virus causes haemorrhagic fever and internal bleeding; it is highly infectious as well as contagious.
The MoH coordinates a national task force and is cooperating with stakeholders, WHO and the Center for Disease Control and Prevention (CDC) in order to control the outbreak. Kibaale hospital has established a temporary isolation ward for suspected, probable and confirmed cases, with the collaboration of Médecins Sans Frontières (MSF).
At the moment, WHO does not recommend that any travel or trade restrictions are applied to Uganda.

Discovered a New Carbon-Carbon Chemical Bond
A group of researchers from Hokkaido University has provided the first experimental evidence of the existence of a new type of chemical bond: the single-electron covalent bond, theorized by Linus Pauling in 1931 but never verified until now. Using derivatives of hexaarylethane (HPE), the scientists were able to stabilize this unusual bond between two carbon atoms and study it with spectroscopic techniques and X-ray diffraction. This discovery opens new perspectives in understanding bond chemistry and could lead to the development of new materials with innovative applications.

After nearly a year of review, on September 25, a study was published in Nature that has sparked a lot of discussion, especially among chemists. A group of researchers from Hokkaido University synthesized a molecule that experimentally demonstrated the existence of a new type of chemical bond, something that does not happen very often.
