Here is what I am reading today:

“Chief Technology Officer for the company, Sharon Presnell explained to those at the conference that Organovo’s 3D printing process involves printing out two different types of liver cells—hepatocytes and stellates—along with the linings of blood cells. The result is tissue that the company claims looks, feels and in many ways, behaves just like real human liver tissue. They say it can produce albumin, cholesterol and cytochrome P450s (enzymes that metabolize drugs)—and because of that is much better suited for testing new drugs. She added that the new 3D printing process marks another step towards the creation of full-size human livers for implanting in people to replace those that have failed, and even went so far as to predict that such technology will come to pass in her lifetime. “

“Mice with mutations in these genes show similar kidney disease to humans. In this recent collaborative study with groups at University College London and the University of Cambridge, Professor Sharpe and his team identified specific facial and dental abnormalities in PKD2 mutant mice. These features develop after birth and correlate with the function of PKD2 as a mechanoreceptor, and thus influence the structure of the face by influencing jaw strength and other features. To the naked eye, patients with ADPKD are not known to have any characteristic facial or dental features. To test whether there was any relationship in humans with these mutations, 3D facial shape analysis—using techniques developed by Professor Peter Hammond’s lab at UCL’s Institute of Child Health—was carried out on a small group of patients (11 female, 8 male, mean age 48 years).”

“Lead researcher Mark Wexler describes some of the challenges he and his colleagues – Andrew Glennerster, Patrick Cavanagh, Hiroyuki Ito, and Takeharu Seno – encountered in conducting their study. “We had the idea that these illusory jumps are related to dmax, the supposed upper speed limit on the steps that leads to motion perception, varies between individuals, and must be measured using random textures,” Wexler tells Medical Xpress. “For displacements below dmax you’re supposed to see the motion more or less correctly,” he explains, “while for displacement above dmax you’re just supposed to see noise – and the latter also turns out to be false.””

“”If a kid doesn’t interact in the right way because of a social deficit, that could be a communication difficulty, but you wouldn’t really say that their linguistic ability in a computational sense was hurt,” says Kenneth Wexler, a professor of brain and cognitive sciences at MIT. Wexler, a psychologist and linguist who has previously developed comprehensive models of how children learn language as part of normal development, has spent the past few years studying autistic children, in hopes of creating a framework to help pinpoint the source of their communication difficulties.”

““Many hallucinations are accompanied by a feeling of astonishment,” Sacks says. Although most of us don’t feel like we have much direct control over even our everyday process of creativity, we can still usually tell the difference between imagining something – a musical composition or a narrative arc – and witnessing a performance of it. Hallucinations blur that boundary.”

“”It may be particularly useful to start both at the same time,” said Abby King, PhD, lead author of the study and a professor of health research and policy and of medicine. “If you need to start with one, consider starting with physical activity first.” The few published studies on how to introduce more than one shift in healthy habits report conflicting findings—and few have looked at exercise and dietary change together. In examining the issue, the researchers also wanted to study people who specifically complained that the demands of their schedules didn’t give them enough time to make healthy dietary and exercise choices. The reasoning was that if successful programs could be developed for these time-strapped individuals, they would likely work for others, as well.”
