From language to literature, from music to mathematics, a single protein appears central to the formation of the long-term memories needed to learn these and all other disciplines, according to a team of researchers led by scientists at the National Institute of Child Health and Human Development of the National Institutes of Health. Their findings appear in the October 15 issue of Science.
The protein is known as mBDNF, which stands for mature brain-derived neurotrophic factor. It appears to chemically alter neurons, boosting their ability to communicate with one another. "Most of what we accomplish as human beings depends on what we learn," said Duane Alexander, M.D., Director of the National Institute of Child Health and Human Development. "This discovery brings the possibility of studying this protein system in people with disorders of learning and memory and perhaps designing new medications that might help to compensate for these problems."
The study was conducted by NICHDs Petti Pang, Ph.D, and Bai Lu, Ph.D, along with their colleagues at NICHD, Weill Medical College of Cornell University in New York City, and The Chinese University of Hong Kong. Researchers recognize two broad categories of memory--short term memory, and long term memory. Short term memory refers to the transient memories that last from minutes to hours. Long term memory refers to the ability to remember things for more than a day--sometimes for many years.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
