Soft Sensors Map Skin Mechanics

Slashdot - Sun, 05/24/2015 - 9:33am
MTorrice writes: An international research team has built electronic, flexible patches that can measure the mechanical properties of skin and other biological tissue. The sensors consist of nanoribbons of a piezoelectric material, lead zirconate titanate, which deforms when jolted with electrical energy and, conversely, produces electricity when it's deformed. The researchers mapped the skin elasticity of dozens of patients in the clinic, building up quantitative data on healthy and damaged tissue. The information could help doctors better assess conditions such as dermatitis and skin cancer. The team believes that similar sensors could be implanted inside the body to monitor blood vessels and other soft tissue for damage or dysfunction.

Universe's Dark Ages May Not Be Invisible After All

Slashdot - Sun, 05/24/2015 - 8:27am
StartsWithABang writes: The Universe had two periods where light was abundant, separated by the cosmic dark ages. The first came at the moment of the hot Big Bang, as the Universe was flooded with (among the matter, antimatter and everything else imaginable) a sea of high-energy photons, including a large amount of visible light. As the Universe expanded and cooled, eventually the cosmic microwave background was emitted, leaving behind the barely visible, cooling photons. It took between 50 and 100 million years for the first stars to turn on, so in between these two epochs of the Universe being flooded with light, we had the dark ages. Yet the dark ages may not be totally invisible, as the forbidden spin-flip-transition of hydrogen may illuminate this time period after all.

Nerve Cells Made From Blood Cells

Slashdot - Sun, 05/24/2015 - 5:31am
BarbaraHudson writes: CBC reports that Canadian scientists are turning blood into nerve cells. They do so by manipulating stem cells that have been taken from a patient's blood, eventually switching them into neural stem cells (abstract). These can then give rise to multiple different nerve cells suitable for use in the rest of the body. Team leader Mick Bhatia said, "We can actually take a patient's blood sample, as routinely performed in a doctor's office, and with it we can produce one million sensory neurons. We can also make central nervous system cells." They're working on turning the neural stem cells into motor neurons for treatment of diseases like Parkinson's and Alzheimer's.
