How a 3D Printer Helped a Child Breathe Again

When Kaiba Gionfriddo was born, his parents never expected to have to look on, helpless, as his windpipe collapsed daily and stopped him from breathing. They were desperate—so when a team of researchers suggested that a 3D printer could help, they leapt at the chance. Read more…

Georgia Tech and Udacity Partner for Online M.S. in Computer Science

Georgia Tech and Udacity — the online courseware project led by Sebastian Thrun — have announced a plan to offer an accredited M.S. Computer Science program online. The two organizations are also working with AT&T. This is the first time a major university has made an actual degree available solely through the MOOC format. Getting a degree in this manner is going to be much cheaper than a traditional degree: “… students also will pay a fraction of the cost of traditional on-campus master’s programs; total tuition for the program is initially expected to be below $7,000.” U.S. Secretary of Education Arne Duncan said, “Massive open online courses (MOOCs) have quickly become one of the most significant catalysts of innovation in higher education. As parents know all too well, America urgently needs new ideas about how to make higher education accessible and affordable. This new collaboration between Georgia Tech, AT&T and Udacity, and the application of the MOOC concept to advanced-degree programs, will further the national debate — pushing from conversations about technology to new models of instruction and new linkages between higher education and employers.” Georgia Tech is looking at the big picture: “At present, around 160,000 master’s degrees are bestowed in the United States every year in computer science and related subject disciplines; the worldwide market is almost certainly much larger, perhaps even an order of magnitude larger.” Read more of this story at Slashdot.

This wild illusion causes you to see an object in three different ways

There are so many optical illusions that feature an object or picture that can be seen in two different ways. But have you ever seen an illusion that can be interpreted in three different ways? Read more…

How an Aussie University Creates the World’s Best Hackers

bennyboy64 writes “An Australian university appears to be excelling at cultivating some of Australia’s best computer hackers. Following the University of NSW’s students recently placing first, second and third in a hacking war game (the first place winners also won first place last year), The Sydney Morning Herald reports on what exactly about the NSW institution is breeding some of Australia’s best hackers. It finds that a lecturer and mentor to the students with controversial views on responsible disclosure appears to the be the reason for their success.” Read more of this story at Slashdot.

MIT To End Open-Network Policy In Response To Recent Attacks

An anonymous reader writes “MIT announced that despite a long history of running an open network (so that any student can run a server on any port, without any questions asked), it will now end this policy due to recent denial-of-service attacks and gunman hoax. From a letter sent by Executive Vice President and Treasurer Israel Ruiz: ‘I am deeply and personally committed to safeguarding our community, protecting our campus and securing our systems. Together with our colleagues dedicated to campus safety and security, with the support of senior academic leadership and in collaboration with the campus community, we are deploying all necessary resources to this effort. It will require the dedication of all of us to promote safety awareness, complete necessary emergency training, and adhere to reinforced cyber security guidelines. IS&T staff members are working with information technology (IT) leadership and partners across campus in making the changes described above. We continue to explore all opportunities to further strengthen our preparedness, and will communicate additional information as these plans evolve.'” Read more of this story at Slashdot.

New Catalyst Allows Cheaper Hydrogen Production

First time accepted submitter CanadianRealist writes “Electrolysis of water to produce hydrogen is very inefficient without the use of a catalyst. Unfortunately catalysts are currently made of crystals containing rare, expensive toxic metals such as ruthenium and iridium. Two chemists from the University of Calgary have invented a process to make a catalyst using relatively non-toxic metal compounds such as iron oxide, for 1/1000 the cost of currently used catalysts. It is suggested this would make it more feasible to use electrolysis of water to create hydrogen as a method of storing energy from variable green power sources such as wind and solar.” Read more of this story at Slashdot.

A Quarter of Sun-Like Stars Host Earth-Size Worlds

astroengine writes “Although there appears to be a mysterious dearth of exoplanets smaller than Earth, astronomers using data from NASA’s Kepler space telescope have estimated that nearly a quarter of all sun-like stars in our galaxy play host to worlds 1-3 times the size of our planet. These astonishing results were discussed by Geoff Marcy, professor of astronomy at the University of California, Berkeley, during a talk the W. M. Keck Observatory 20th Anniversary Science Meeting on Thursday. ’23 percent of sun-like stars have a planet within (1-2.8 Earth radii) just within Mercury’s orbit,’ said Marcy. ‘I’ll say that again, because that number really surprised me: 23 percent of sun-like stars have a nearly-Earth-sized planet orbiting in tight orbits within 0.25 AU of the host stars.'” Read more of this story at Slashdot.
