The largest trial so far conducted using Butterbur extract to treat intermittent allergic rhinitis (hay fever) shows that this plant extract is as effective as a commonly used antihistamine (Telfast 180).
In recent years there have been a few reports of small research trials that give a mixed view about the effectiveness of Butterbur extract for treating intermittent allergic rhinitis (IAR). Now researchers from Germany and Switzerland have published results from a randomised, double-blind, parallel group comparison study involving 330 patients in 11 centres. They found that treatment with butterbur extract was as effective at combating symptoms of IAR as treatment with a conventional antihistamine (Telfast 180). In addition they found that Butterbur extract did not cause drowsiness.
‘Despite being a herbal drug, Butterbur Ze339 has now been subject to a series of well controlled trials and should be considered as an alternative treatment for IAR,’ says lead researcher Andreas Schapowal.

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...
