Cell biology: How cellular powerhouses call for help when under stress      (via sciencedaily.com)     Original source 

Originally, the powerhouses of higher cells, the mitochondria, were independent organisms. Researchers have investigated to what extent their metabolism has blended with that of their host cells in the course of evolution, using the example of a mitochondrial stress response. They have discovered that mitochondria send two different biochemical signals. These are processed together in the cell and trigger a support mechanism to restore cellular balance (homeostasis).

Researchers develop 'in vivo' RNA-based gene editing model for blood disorders      (via sciencedaily.com)     Original source 

In a step forward in the development of genetic medicines, researchers have developed a proof-of-concept model for delivering gene editing tools to treat blood disorders, allowing for the modification of diseased blood cells directly within the body. If translated into the clinic, this approach could expand access and reduce the cost of gene therapies for blood disorders, many of which currently require patients receive chemotherapy and a stem cell transplant.

Robotic glove that 'feels' lends a 'hand' to relearn playing piano after a stroke      (via sciencedaily.com)     Original source 

A new soft robotic glove is lending a 'hand' and providing hope to piano players who have suffered a disabling stroke or other neurotrauma. Combining flexible tactile sensors, soft actuators and AI, this robotic glove is the first to 'feel' the difference between correct and incorrect versions of the same song and to combine these features into a single hand exoskeleton. Unlike prior exoskeletons, this new technology provides precise force and guidance in recovering the fine finger movements required for piano playing and other complex tasks.

Acoustic waves may be able to control how particles sort themselves. While researchers have been able to separate particles based on their shape -- for example, bacteria from other cells -- for years, the ability to control their movement has remained a largely unsolved problem, until now. Using ultrasound technology and a nozzle, researchers have separated, controlled and ejected different particles based on their shape and various properties.

Wind farm noise exposure doesn't wake people up from their slumber more than road traffic noise      (via sciencedaily.com)     Original source 

Short exposure to wind farm and road traffic noise triggers a small increase in people waking from their slumber that can fragment their sleep patterns, according to new research. But importantly, the new study also shows that wind farm noise isn't more disruptive to sleep than road traffic, which was a little more disruptive at the loudest audio level but not at more common levels. Sleep researchers have studied the impact of exposure to wind farm noise during sleep in three new scientific publications to better understand its impact.
