Scientists at the John Innes Centre (JIC), Norwich, UK, today report a breakthrough in understanding how plant cells control the direction of their growth. The report, in the international scientific journal Nature, describes a gene (called SCN1) which controls the activity of an enzyme that is critical to cell growth. The researchers have found that SCN1 keeps cell growth in check.
“This is an exciting discovery because the direction of cell growth is very important in determining the shape of plant cells and this controls the overall shape and structure of the plant”, says Professor Liam Dolan (project leader at JIC). “We already know about some of the processes involved in cell growth but this is a new insight into how they are localised so that cells can be made to grow in a particular direction”.
The researchers made their discovery from studies on root hair formation on roots of the model plant Thale Cress (Arabidopsis thaliana). Root hairs are important to the plant as they dramatically increase the surface area of the roots, providing a large surface through which water and minerals can be absorbed.

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.

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...
