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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
