A study by New York University researchers reveals a new function for the nerve cells that regulate circadian rhythms of behavior in fruit flies.
The nerve cells, called pacemaker neurons, contain a molecular clock that controls a 24-hour circadian rhythm in activity similar to the rhythms in sleep/wake cycles found in humans and many other organisms. It was previously known that pacemaker neurons receive visual signals to reset their molecular clocks, but scientists did not have any evidence that they transmitted information to their target cells, as most other neurons do.
The current study shows that pacemaker neurons do in fact transmit signals and are required for a rapid behavior, according to the paper, published in the January 20th issue of Neuron. The study was conducted by Esteban O. Mazzoni, a graduate student in NYUs Biology Department, Biology Professor Claude Desplan, and Assistant Biology Professor Justin Blau. The finding suggests it may be possible to identify genes that can be used to treat problems such as sleep disorders and jet lag.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
