Fossil-hunting expeditions to Tanzania, Zambia and Antarctica provide new insights
Predecessors to dinosaurs missed the race to fill habitats emptied when nine out of 10 species disappeared during Earth’s largest mass extinction 252 million years ago.
Or did they?
That thinking was based on fossil records from sites in South Africa and southwest Russia.
It turns out, however, that scientists may have been looking in the wrong places. (more…)
South African scientists to develop rugged microservers to handle the harsh desert conditions, explore new computer architectures and develop advanced algorithms for radio astronomy imaging
Pretoria, South Africa – 11 Mar 2013: Square Kilometer Array (SKA) South Africa, a business unit of the country’s National Research Foundation is joining ASTRON, the Netherlands Institute for Radio Astronomy, and IBM in a four-year collaboration to research extremely fast, but low-power exascale computer systems aimed at developing advanced technologies for handling the massive amount of data that will be produced by the SKA, which is one of the most ambitious science projects ever undertaken.
The SKA is an international effort to build the world’s largest and most sensitive radio telescope, which is to be located in Southern Africa and Australia to help better understand the history of the universe. The project constitutes the ultimate Big Data challenge, and scientists must produce major advances in computing to deal with it. The impact of those advances will be felt far beyond the SKA project—helping to usher in a new era of computing, which IBM calls the era of cognitive systems. (more…)
Microbe-eating flies from at least three different locations around the world recently have evolved into herbivores, feeding on some of the most toxic plants on Earth. Fly detectives and UA evolutionary biologists Noah Whiteman and Richard Lapoint are trying to find out what genetic pathways led the flies to such a major change of lifestyle.
For millennia, they buzzed through the woods, contentedly munching yeasts off the surfaces of leaves, bracken and rotting duff on the forest floor. But now, flies in the family Drosophilidae, whose disparate members dwell in areas all across the planet, have evolved into all-out vegetarians with a wicked diet of plants that are deadly to most other organisms.
What, University of Arizona scientists would like to know, has caused these flies, yeast-feeders for nearly 80 million years, to independently go cold turkey with respect to their formerly meaty diets? (more…)
Financial, healthcare, government and electronics clients tap IBM SmartCloud Enterprise+; IBM SmartCloud for SAP Applications now available globally
ARMONK, N.Y. – 29 Jan 2013: IBM today announced global availability for its cloud service on five continents—plus a new center opening in Spain—based on its industry-leading sourcing business to host SAP® applications and other core operations. Now clients can turn to cloud computing for enterprise applications while reducing the overall cost of IT and at the same time, expanding online access and investing in innovative analytics, social business and mobile computing.
Many organizations are eager to leverage the economic advantages of cloud computing to run their critical applications on the cloud. These applications require deep technical expertise, around-the-clock customer service, tight security and ongoing maintenance – features typically found in IT sourcing arrangements but not in the “one-size-fits-all” model of self-service clouds.

WASHINGTON — On average, Americans die sooner and experience higher rates of disease and injury than people in other high-income countries, says a new report from the National Research Council and Institute of Medicine.
The report finds that this health disadvantage exists at all ages from birth to age 75 and that even advantaged Americans—those who have health insurance, college educations, higher incomes and healthy behaviors—appear to be sicker than their peers in other rich nations. (more…)
Passion for sport is unrivalled in its energy and dedication and so it’s no wonder that people are so keen to travel the world to see their favourite athletes and teams play abroad. These tours offer a unique opportunity to follow your sport and see some great global destinations at the same time.
Travelling abroad to follow your favourite sport is a unique and highly rewarding experience, allowing you to experience a different country, engage with their culture and discover the wonders of how other peoples and nations watch and enjoy sports. Organised tours are often the best way to get involved with international sport as they do an excellent job of combining all the necessary aspects without any hassle for your tickets to all the most important sporting events, accommodation and transport to make getting there very easy and scheduled free time to allow you to explore the surroundings of your destination.(more…)
Antidepressants are the most widely used treatment for people with moderate to severe depression.
However, up to two thirds of people with depression don’t respond fully to this type of treatment. New findings have shown cognitive behavioural therapy (CBT), provided in addition to usual care, can reduce symptoms of depression and help improve patients’ quality of life.
This is the first large-scale trial to test the effectiveness of CBT – a type of talking psychotherapy- given in addition to usual care that includes antidepressants. The National Institute for Health Research Health Technology Assessment (NIHR HTA)-funded CoBalT study aimed to determine the best ‘next step’ treatment for people whose depression had not responded to medication alone.

Researchers have discovered what may be the earliest dinosaur, a creature the size of a Labrador retriever, but with a five foot-long tail, that walked the Earth about 10 million years before more familiar dinosaurs like the small, swift-footed Eoraptor and Herrerasaurus.
The findings mean that the dinosaur lineage appeared 10 million to 15 million years earlier than fossils previously showed, originating in the Middle Triassic rather than in the Late Triassic period. (more…)
