A novel technique that uses quantum light to measure temperature at the nanoscale

Posted by in categories: biotech/medical, nanotechnology

Being able to measure, and monitor, temperatures and temperature changes at miniscule scales—inside a cell or in micro and nano-electronic components—has the potential to impact many areas of research from disease detection to a major challenge of modern computation and communication technologies, how to measure scalability and performance in electronic components.

Scientists Have Finally Achieved Direct Counterfactual Quantum Communication

Posted by in categories: particle physics, quantum physics

Quantum communication is a strange beast, but one of the weirdest proposed forms of it is called counterfactual communication — a type of quantum communication where no particles travel between two recipients.

Theoretical physicists have long proposed that such a form of communication would be possible, but in 2017, for the first time, researchers were able to experimentally achieve it — transferring a black and white bitmap image from one location to another without sending any physical particles.

Multivascular networks and functional intravascular topologies within biocompatible hydrogels

Posted by in categories: biotech/medical, food, mathematics, space travel

In air-breathing vertebrates, the circulatory and pulmonary systems contain separate networks of channels that intertwine but do not intersect with each other. Recreating such structures within cell-compatible materials has been a major challenge; even a single vasculature system can be a burden to create. Grigoryan et al. show that natural and synthetic food dyes can be used as photoabsorbers that enable stereolithographic production of hydrogels containing intricate and functional vascular architectures. Using this approach, they demonstrate functional vascular topologies for studies of fluid mixers, valves, intervascular transport, nutrient delivery, and host engraftment.

Science, this issue p. 458

Solid organs transport fluids through distinct vascular networks that are biophysically and biochemically entangled, creating complex three-dimensional (3D) transport regimes that have remained difficult to produce and study. We establish intravascular and multivascular design freedoms with photopolymerizable hydrogels by using food dye additives as biocompatible yet potent photoabsorbers for projection stereolithography. We demonstrate monolithic transparent hydrogels, produced in minutes, comprising efficient intravascular 3D fluid mixers and functional bicuspid valves. We further elaborate entangled vascular networks from space-filling mathematical topologies and explore the oxygenation and flow of human red blood cells during tidal ventilation and distension of a proximate airway. In addition, we deploy structured biodegradable hydrogel carriers in a rodent model of chronic liver injury to highlight the potential translational utility of this materials innovation.

Man cracks his neck, ends up giving himself a stroke

Posted by in category: futurism

I’m not going to venture a guess as to what percentage of the population regularly cracks their necks, but I have to imagine it’s pretty high. A quick bend left and right is all it normally takes to produce the satisfying “pop,” and for most of us it seems like little more than a harmless habit.

Apparently that’s not the case, and the story of one 28-year-old Oklahoma man is a strong reminder that toying with one’s own spine can be a dangerous thing. A simple neck crack is all it took to turn Josh Hader’s life upside down, and he knew within moments that he had accidentally done some serious damage.
