Weizmann Institute finding may lead to new treatments for psychological trauma
Is it possible to intentionally forget specific memories, without affecting other memories? Many would undoubtedly be happy to learn that unpleasant memories might be erased. This ability could be especially significant when it comes to the kind of traumatic memories that are debilitating to those experiencing them. It may well be that in the future, we will be able to wipe out, or at least dim, certain types of memories with controlled accuracy. A new fundamental rule governing the workings of the brain, recently discovered by a team of scientists in the Weizmann Institute of Science, headed by Prof. Yadin Dudai of the Neurobiology Department, constitutes a step towards reaching this goal.
Every memory that we acquire undergoes a "ripening" process (called consolidation) immediately after it is formed. In this process, it becomes impervious to outside stimulation or drugs that would obliterate it. Until recently, the accepted dogma was that for each separate item of memory, consolidation occurs just once, after which the time window that allows for "memory erasing" closes (usually about an hour or two after the memory is acquired).

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
