Forsyth Study Also Provides Insight to Possible Complications from Serotonin Blocking Drugs
Researchers at The Forsyth Institute have discovered that the transport mechanisms for serotonin — the chemical substance involved in transmitting signals between neurons, and which has a role in anxiety and mood disorders — play a key role in determining where organs are positioned in the body during embryonic development. Transporters bring serotonin into cells. The research team, led by Dr. Michael Levin, found that when the transport of serotonin into cells was blocked, normal development was disrupted in frog and chick embryos.
In particular, left-right asymmetry, the process through which cells “know” which side they are on as they form body organs such as the heart and liver, is controlled by serotonin transporters. Michael Levin, PhD., Associate Member of the Staff, conducted his research with substances commonly used to treat mood disorders in humans including the drug Prozac. These drugs address chemical imbalances in the brain by blocking serotonin’s removal from the space between neurons.

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...
