New York City’s late summer/early fall 2000 mosquito spraying session, designed as an effort to minimize the spread of West Nile virus, did not increase the number of people seeking emergency care for asthma-related problems, according to a study published today in the August issue of the peer-reviewed journal Environmental Health Perspectives (EHP). The study found no correlation between the application of sumithrin—a pyrethroid pesticide—in the 162 residential zip codes sprayed between July and September 2000 and asthma-related symptom cases presenting at the city’s 11 public hospital emergency departments.
Researchers evaluated rates of emergency department visits over a 14-month period. The study also incorporated air quality data, including daily measures of ozone, air particulates, and temperature, which can cause fluctuations in the number of people seeking treatment for asthma. .All zip codes in New York City were included in the study, except those in Staten Island, which lacks a public hospital.
The number of visits was similar in the 3-day periods before and after spraying. The researchers also looked specifically at incidents in children under 15 years and for aggravation of chronic obstructive pulmonary disease. No correlation to spraying was found in either group.

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...
