Stem cell discovery could transform the treatment of type 1 diabetes. Bill Condie reports.

Scientists have for the first time created insulin-producing cells in the laboratory, a discovery that could transform the way we treat diabetes.
Taking their cue from salamander regeneration, a team led by the University of New South Wales says that a stem cell therapy capable of regenerating any human tissue damaged by injury, disease, or aging could be available within a few years, thanks to an innovative new technique.
While stem cells have worked wonders in medicinal research, showing signs of curing everything from spinal cord injuries to blindness, they’ve always had their shortcomings. But one study is promising a new “game changing” technique for stem cells.

Imagine shirts that act as antennas for smartphones or tablets, workout clothes that monitor fitness level or even a flexible fabric cap that senses activity in the brain!
All this will soon be possible as the researchers working on wearable electronics have been able to embroider circuits into fabric with super precision — a key step toward the design of clothes that gather, store or transmit digital information.
“A revolution is happening in the textile industry. We believe that functional textiles are an enabling technology for communications and sensing and one day, even for medical applications like imaging and health monitoring,” said lead researcher John Volakis from Ohio State University.
The discomfort and stigma of loose or missing teeth could be a thing of the past as Griffith University researchers pioneer the use of 3D bioprinting to replace missing teeth and bone.
The three-year study, which has been granted a National Health and Medical Research Council Grant of $650,000, is being undertaken by periodontist Professor Saso Ivanovski from Griffith’s Menzies Health Institute Queensland.
As part of an Australian first, Professor Ivanovski and his team are using the latest 3D bioprinting to produce new, totally ‘bespoke,’ tissue engineered bone and gum that can be implanted into a patient’s jawbone.
So after 40 years of prescribing low fat diets & demonising cholesterol, the largest & longest clinical experiment ever (40 years, 9,000 patients, randomly assigned diets) shows that “Patients who lowered their cholesterol, presumably because of the special diet, actually suffered MORE heart-related deaths than those who did not.”
In other words, if you’ve been cutting on steaks, butter etc. for 4 years or more, you may have INCREASED your mortality rate from heart disease by %8.
Oops?

A fuller accounting of the results of a massive government-funded experiment on fatty foods challenges the conventional advice about what is healthy, and what is not.
Hmm… That would explain Alzheimer disease — It’d be like some sort of unabashedly evil version of a smart phone data caps!
Or not.

NEW YORK — Is the universe just an enormous, fantastically complex simulation? If so, how could we find out, and what would that knowledge mean for humanity?
These were the big questions that a group of scientists, as well as one philosopher, tackled on April 5 during the 17th annual Isaac Asimov Debate here at the American Museum of Natural History. The event honors Asimov, the visionary science-fiction writer, by inviting experts in diverse fields to discuss pressing questions on the scientific frontiers.
Neil deGrasse Tyson, director of the museum’s Hayden Planetarium and host of this year’s event, invited five intellectuals to the stage to share their unique perspectives on the problem: Zohreh Davoudi, a nuclear physicist at the Massachusetts Institute of Technology (MIT); Max Tegmark, a cosmologist at MIT whose recent book probes the universe as mathematics; James Gates, a physicist at the University of Maryland who discovered strange, error-correcting codes deep in the equations of supersymmetry; Lisa Randall, a physicist at Harvard University who thinks the simulation question is more or less irrelevant; and David Chalmers, a philosopher at New York University who regularly questions the reality that conscious minds perceive.

Now, we’re beginning to see some of the ways that virtual reality will impact modern medicine with a company by the name of Medical Realities leading the way.
Co-founded by Dr. Shafi Ahmed, Medical Realities is a medical training firm that specializes in virtual reality, augmented reality and serious games using consumer-level devices like the Oculus Rift. In just a few days, he and his team of medical professionals will be livestreaming the removal of a tumor from the colon of a man in his 70s.
