The turtle has been in no rush to give up the secret of its shell — but after two centuries of close study, scientists are filling in the story of a structure unique in the history of life.
New research led by Tyler Lyson of Yale University and the Smithsonian Institution pushes back the origins of the turtle shell by about 40 million years, linking it to Eunotosaurus, a 260-million-year-old fossil reptile from South Africa. The work strengthens the fossil record and bolsters an existing theory about shell development while providing new details about its precise evolutionary pathway.(more…)
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…)
“WaterWatchers,” a new mobile app, harnesses the power of crowdsourcing
Johannesburg, South Africa – 22 Mar 2013: IBM marks World Water Day with the launch of a crowdsoucing project to help capture, share and analyze information about the water distribution system in South Africa. The project, called “WaterWatchers,” is driven by a new mobile phone application and SMS capability that will enable South African citizens to report water leaks, faulty water pipes and general conditions of water canals. Every update will provide vital data points to an aggregated “WaterWatchers” report to create a single view of the issues challenging South Africa’s water distribution system.
The free app, which is currently available for Android and available for download at www.ibmwaterwatchers.co.za, and the SMS capability* together provide an easy way for anyone to collect and report issues on local waterways and pipes to a centralized portal. After taking a photo and answering three simple questions about the particular water canal or pipe, the data is uploaded in real-time to a central database. After 30 days, the data will be analyzed and aggregated into a meaningful “leak hot spot” map for South Africa. (more…)
Washington, D.C.— It has long been believed that male lions are dependent on females when it comes to hunting. But new evidence suggests that male lions are, in fact, very successful hunters in their own right. A new report from a team including Carnegie’s Scott Loarie and Greg Asner shows that male lions use dense savanna vegetation for ambush-style hunting in Africa. Their work is published in Animal Behavior. Female lions have long been observed to rely on cooperative strategies to hunt their prey. While some studies demonstrated that male lions are as capable at hunting as females, the males are less likely to cooperate, so there were still questions as to how the males manage to hunt successfully. The possibility that male lions used vegetation for ambushing prey was considered, but it was difficult to study given the logistics and dangers of making observations of lions in densely vegetated portions of the African savanna.

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…)
Award-winning journalist, activist, and author Charlayne Hunter-Gault told a packed audience at Yale that lessons learned from the civil rights movement still have relevance for current and future generations.
Hunter-Gault delivered a lecture titled “Social Justice, Equity, and Public Health” during a Branford College master’s tea on Feb. 5. (more…)
New York is a hub. This city has served as a focal point for so many things American, from fashion to publishing to bagels and so much more. Now the “city that never sleeps” is becoming a hub for cruise travel. You can now cruise around the world, right from New York.
Here are four major destinations that you can discover on a cruise from New York.
Europe – Set sail for a European adventure on a transatlantic cruise. This sailing has old world charm, as you cross the ocean like many immigrants did generations ago, to experience the new world and embark upon a new life. You can trace back your ancestor’s routes and see the precious places they came from. (more…)
Elizabeth Bradley started her career on the faculty at Yale in 1996 and currently serves in a variety of roles at the University, including professor of public health, faculty director for the Global Health Initiative and the Global Health Leadership Institute, and master of Branford College.
Her research focuses on strengthening health systems and has contributed important findings about organizational change and quality of care within the hospital, nursing home, and hospice settings. She has been involved with several international projects including research in China, Ethiopia, Liberia, South Africa, and the United Kingdom.
Bradley spoke recently about her work on campus and around the world, and the many other items on her “to-do” list. (more…)
