A New Form of Synaptic Plasticity in Pain Pathways

Posted by in categories: biotech/medical, neuroscience

Nice.


Chronic pain is thought to involve the long-lasting strengthening of synapses, akin to what happens during the formation of new memories. This phenomenon, known as long-term potentiation (LTP), is triggered when neurons on both sides of a synapse are active at the same time. But now, Jürgen Sandkühler, Medical University of Vienna, Austria, and colleagues provide evidence that LTP in nociceptive circuits arises in a different way.

By simultaneously activating two types of glial cells―astrocytes and microglia―the researchers were able to produce LTP at synapses that connect peripheral C-fibers and lamina I neurons in the dorsal horn spinal cord. They also showed that with high-frequency stimulation of C-fibers, glial cells strengthen active and inactive synapses through their release of the NMDA receptor co-agonist D-serine and the cytokine tumor necrosis factor (TNF). Moreover, these molecules traveled to distant synapses, perhaps explaining why pain hypersensitivity can develop in areas surrounding or far away from an injury.

Scientists are Creating a New Diamond Predicted to be Harder Than a Jeweler’s Diamond

Posted by in categories: materials, nanotechnology

For all my Lab friends who utilize Spectrometers, drill bit fans as well as many of us QC fans. A new stronger syn. diamond being developed.


But you won’t find this diamond on any engagement rings — it will help cut through ultra-solid materials on mining sites.

Step aside, girls. Diamonds may now be a miner’s best friend, thanks to scientists from Australian National University (ANU).

Viewpoint: A New Era for the Ampere

Posted by in category: quantum physics

Improving Precision with Quantum — A new Precise Quantum Current Source developed to ensure calibrated currents meet the new redefined International System of Units.


A precision quantum current source has been designed to calibrate currents in terms of the soon-to-be-redefined International System of Units.

Metrologists are conservative by nature, knowing that the premature adoption of a new measurement standard could lead to confusion in both science and commerce. So it is a big deal that the International System of Units (SI) is poised to undergo its first major overhaul since its birth in 1960. Two years from now at the General Conference on Weights and Measures in Paris, officials will adopt a new SI in which every unit can be obtained from fixed values of several fundamental constants [1]. All eyes are on the kilogram, which will no longer be defined by the mass of a cylinder of platinum-iridium alloy that has been kept in a Parisian vault since it was fabricated in 1889. Somewhat overlooked, however, are advances in standards for electrical resistance and voltage, without which the new SI would not be possible.
