Researchers have discovered the first genetic component of a biochemical pathway in the brain that governs the indelible imprinting of fear-related experiences in memory.
The gene identified by researchers at the Howard Hughes Medical Institute at Columbia University encodes a protein that inhibits the action of the fear-learning circuitry in the brain. Understanding how this protein quells fear may lead to the design of new drugs to treat depression, panic and generalized anxiety disorders.
The findings were reported in the December 13, 2002 issue of the journal Cell, by a research team that included Howard Hughes Medical Institute (HHMI) investigators Eric Kandel at Columbia University and Catherine Dulac at Harvard University. Lead author of the paper was Gleb Shumyatsky, a postdoctoral fellow in Kandel’s laboratory at Columbia University. Other members of the research team are at the National Institutes of Health and Harvard Medical School.

Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
A research team from the Max Planck Institute for the Structure of Dynamics (MPSD) and the University of Oxford has managed to drive a prototypical antiferromagnet into a new magnetic state using terahertz frequency light. Their groundbreaking method produced an effect orders of magnitude larger than previously achieved, and on ultrafast time scales. The team’s work has just been published in Nature Physics.
Magnetic materials have been a mainstay in computing technology due to their ability to permanently store information in their magnetic state. Current...
