Sign language gloves, intended to help people with visual disabilities, turn fingerspelling into text on a smartphone or computer. But fingerspelling makes up only a small part of the American Sign La...
Carbon Feedback from Forest Soils will Accelerate Global Warming,26-Year Study Projects
Carbon Feedback Forest Soils Accelerate Global Warming 26-Year Study Projects
2017/10/25
After 26 years, the world’s longest-running experiment to discover how warming temperatures affect forest soils has revealed a surprising, cyclical response: Soil warming stimulates periods of abundan...
Tactile feedback adds ‘muscle sense’ to prosthetic hand
Tactile feedback adds muscle sense prosthetic hand
2017/7/21
Engineers working to add “muscle sense” to prosthetic limbs found that tactile feedback on the skin allowed blindfolded test subjects to more than double their ability to discern the size of objects g...
For the first time in humans,researchers use brain surface stimulation to provide ‘touch’ feedback to direct movement
humans researchers brain surface stimulation touch’ feedback direct movement

In the quest torestore movement to people with spinal cord injuries, researchers have focused on getting brain signals to disconnected nerves and muscles that no longer receive messages that would spu...
Negative feedback loops help maintain function of mutated proteins
Negative feedback loops maintain function mutated proteins
2016/7/4
Negative feedback is a universal control mechanism that lets a system’s output throttle its input. If an engine revs up, negative feedback tapers its power source. But if the engine slows down, it re-...
For decades, astrophysicists have encountered a puzzling contradiction: although many galactic-wind models—simulations of how matter is distributed in our universe—predict that the majority of the "no...
The c-MYC oncoprotein, the NAMPT enzyme, the SIRT1-inhibitor DBC1, and the SIRT1 deacetylase form a positive feedback loop
The c-MYC oncoprotein NAMPT enzyme SIRT1-inhibitor DBC1 SIRT1 deacetylase
2012/2/1
Silent information regulator 1 (SIRT1) represents an NAD+-dependent deacetylase that inhibits proapoptotic factors including p53. Here we determined whether SIRT1 is downstream of the prototypic c-MYC...
Carbon-cycle feedback smaller, but still positive（图）
Carbon-cycle global temperature the biosphere’s ability
2010/1/28
Researchers in Switzerland and Germany have analysed data stretching back over 1000 years to get the best estimate yet of how changes in global temperature affect the biosphere’s ability to soak up ca...
Low-level clouds are involved in a positive feedback mechanism that could exacerbate global warming — according to a study of cloud and temperature records from the north-eastern Pacific Ocean. Scient...
