LAGUNA HILLS, California, USA -- Researchers at MetroLaser, Inc., have developed a new design for a digital streak camera that captures full-color images of projectiles traveling up to 3350 m/s, which is 10 times the speed of sound. This system was designed to replace the outdated film-based streak cameras that are still in use at high-speed test tracks.

Research at the University of Sheffield, published in the latest issue of Water Science and Technology: Water Supply, points the way to more sophisticated and targeted methods of ensuring our drinking water remains safe to drink, while still reducing the need for chemical treatments and identifying potential hazards more quickly.
In a large population of Medicare beneficiaries with heart failure who underwent implantation of a cardiac resynchronization therapy defibrillator, patients who had the cardiac characteristics of left bundle-branch block and longer QRS duration had the lowest risks of death and all-cause, cardiovascular, and heart failure readmission, according to a study in the August 14 issue of JAMA.
Women are less likely to take part in corporate crime and fraud even though more women now work in corporations and serve at higher levels of those organizations, according to a team of sociologists.
The researchers examined a database of recent corporate frauds and found that women typically were not part of the conspiracy. When women did play a role, it was rarely a significant one.
Congregation size has an impact on how people view the reasons for racial inequality in America, according to a new study by researchers at Baylor University and the University of Southern California.
Those who attend very large congregations do not tend to attribute social divisions between blacks and whites to discrimination or lack of quality education, but to something other than structural failings in society, said Ryon J. Cobb, a postdoctoral research associate at USC's Roybal Institute on Aging.

A survey, run by Strathclyde academics on behalf of the Scottish Beekeepers' Association, indicated 31.3 per cent of managed honey bee colonies in Scotland failed to survive last winter – almost double the previous year's loss rate of 15.9 per cent.
Dr Alison Gray and Magnus Peterson, of Strathclyde's Department of Mathematics and Statistics, warn the figures ought to be of major concern because bees play a pivotal role in crop pollination, agricultural yields and, therefore, food supply and prices.

A new study shows that the incidence of ischemic stroke -- the most common type of stroke caused by a clot in the blood vessels of the brain -- among non-Hispanic Whites and Mexican Americans over age 60 has declined over the past decade.
NEW YORK CITY — The decline and disappearance of stable, unionized full-time jobs with health insurance and pensions for people who lack a college degree has had profound effects on working-class Americans who now are less likely to get married, stay married, and have their children within marriage than those with college degrees, a new University of Virginia and Harvard University study has found.
The research, "Intimate Inequalities: Love and Work in a Post-Industrial Landscape," will be presented at the 108th Annual Meeting of the American Sociological Association.
COLUMBUS, Ohio -- Growing up with siblings may provide some protection against divorce as an adult, a new nationwide study reveals.
And the more siblings, the better: Each additional sibling a person has (up to about seven) reduces the likelihood of divorce by 2 percent.
The practical difference between having no siblings and having one or two isn't that much in terms of divorce, said Doug Downey, co-author of the study and professor of sociology at The Ohio State University.
