New technique paves the way for instant 3D-printed biological tissues

By - September 17, 2012 1 Picture
3D printing technologies have come a long way since their earliest incarnations as rapid product prototype makers. It's now shaping up as the next disruptive technology and in medical science, 3D printing has huge potential. The latest advance comes from University of California, San Diego Nanoengineering Professor Shaochen Chen, whose group has demonstrated the ability to print three-dimensional blood vessels in seconds. If the technique proves scalable, it could revolutionize regenerative medicine. Read More

New PET scanner halves radiation dose and fits inside an MR scanner

By - August 23, 2012 1 Picture
So you’re unlucky enough to be hit with the real C-word: cancer. That sucks. But what can be worse is that many current medical scanning techniques come with large levels of radiation. The current practice of combining PET (Positron emission tomography) and CT (computerized tomography) scans produces good images, but the cost is high: a dose of radiation ten times the background amount the average human gets in a year. And that’s just one scan. Many cancer patients have to endure multiple scans. A new PET scanner from physicists at the University of Oslo (UiO) cuts the radiation dose in half and is also small enough to fit inside an MR scanner. Although it was developed for animals, the researchers say it could be easily adapted for human clinical examinations. Read More

The science of cute

By - August 15, 2012 1 Picture
Why do small helpless things – babies, kittens, puppies, pandas in baby form – turn even the most cynical human into a helpless wreck? Why don’t we have the same reaction to a baby lizard or fish or bird? What, in short, is this cuteness thing all about? It turns out that the science of cute is far more interesting than you’d think.
