Due to these constraints, most of Africa's population is anticipated to have their first experience with the internet through the mobile channel, says Frost Sullivan (http://www.ict.frost.com) industry analyst Lindsey Mc Donald. This is however about to change when the first undersea cable lands in June this year. And this is only the first of many.

CAPE TOWN, South Africa, May 4 /PRNewswire/ --

A majority of African countries is currently experiencing acute power shortages. This is leading to rolling blackouts and load shedding.

Only 23 per cent of the region has access to electricity. The major problem is the lack of adequate electricity generation capacities and insufficient electricity grids.

African governments have however embarked on substantial investment towards building additional new electricity supply capacities, says Frost Sullivan energy industry analyst Moses Duma. Approximately 80,000MW of new electricity generation capacity is expected to come online by 2030.

OSLO, May 4 /PRNewswire/ --

ODS-Petrodata has recently revised its MSS Cost Index for field development projects based on a worsening outlook for the global economy, commodity prices and contractor margins.

Global field development and pipeline construction investment, not including drilling, is expected to decline by 15 percent in 2009 relative to 2008, primarily linked to a reduction in project costs. The drop in underlying activity will be a more modest 2.0 percent, linked to investments in major ongoing field development projects.

NASA's Fermi Gamma-ray Space Telescope, launched June 2008, has certainly started its career with a (big) bang, discovering a new class of pulsars and watching flaring jets in galaxies billions of light-years away.

Now it's going after another cosmic mystery; high-energy particles in cosmic rays.

The Model 3231 reduces the cost of installation, configuration, monitoring and control with password-protected local and remote management options that enable the device to work with any existing network management policy.

The description of compounds and interactions between atoms is one of the basic objectives of chemistry. Admittedly, chemical bonding models, which describe these properties very well, already exist. However, any deviation from the normal factors may lead to improving the models further. Chemists with Professor Thomas M. Klapötke at Ludwig-Maximilians-Universität (LMU) München have now analyzed a molecule, which has an extremely short bond length.

Increased social stress in childhood and young adulthood has a direct link to later increased dating violence, and that young social stress is impacted by things like unemployment and economic worries, according to Murray Straus, professor of sociology and co-director of the University of New Hampshire Family Research Laboratory.  The research, based on a 32-nation study,  was presented at the conference on “War, Terrorism, and Social Stress: Impacts on Crime and the Criminal Justice System” at the Institute of Criminology, The Hebrew University, Jerusalem, Monday, May 4, 2009.

He studied 14,252 university students from 68 universities in 32 nations in an International Dating Violence Study.

'Drought-proofing' Australia's urban regions by installing large domestic water tanks may enable the dengue mosquito Aedes aegypti to regain its foothold across the country and expand its range of possible infections, according to a new study published in PLoS Neglected Tropical Diseases. 

Dr Nigel Beebe and colleagues from the University of Queensland, CSIRO Entomology, the Australian Army Malaria Institute, and the Communicable Diseases Branch of Queensland Health, Brisbane, challenge the common assumption that climate change will drive the spread of this mosquito. 

An international team of scientists has determined the structure of the chlorophyll molecules in green bacteria that are responsible for harvesting light energy. The team's results one day could be used to build artificial photosynthetic systems, such as those that convert solar energy to electrical energy.
