The Next Generation Of Remote Control Flyers May Be Robo-Bats With Metal Muscles
Tiny flying machines can be used for everything from indoor surveillance to exploring collapsed buildings, but simply making smaller versions of planes and helicopters doesn"t work very well. Instead, researchers at North Carolina State University are mimicking nature"s small flyers - and developing robotic bats that offer increased maneuverability and performance.

Oklahoma Antiabortion Lawmakers Try To Revive Vetoed Bill To Ban Stem Cell Research
Antiabortion lawmakers in Oklahoma on Wednesday attempted to revive vetoed legislation that would have banned embryonic stem cell research in the state by adding the ban to an unrelated bill (HB 1114) that would prohibit human cloning, the AP/CNBC.com reports. House members on Wednesday also added a prohibition on human cloning to that measure. According to Tony Lauinger, chair of Oklahomans for Life, the measure is "narrower" than the vetoed bill and would "ban reproductive cloning, as well as the creation of human embryos for the purpose of harvesting their stem cells."Gov. Brad Henry (D) had vetoed the measure that would have banned stem cell research three weeks ago. The veto subsequently was overwridden by the House and sustained by the Senate. The House on Wednesday also voted 88-6 to approve a measure (HB 1595) that would ban gender selection for genetically modified embryos and ban sex-selective abortions. The measure also would require physicians who perform abortions to report abortion-related information to the state Department of Health. In addition, the bill would require the department to publish annual abortion reports on its Web site and conduct periodic inspections of abortion clinics (AP/CNBC.com, 5/14).

Employee Involvement Programs Key To Workplace Diversity

A new study by a University of Arizona professor shows employee involvement programs that executives adopt to increase efficiency also end up improving their record on diversity. The study was published in a recent issue of the American Journal of Sociology. According to researcher Alexandra Kalev, UA assistant professor of sociology, women and minorities are more successful and have better career opportunities when their companies offer self-directed work teams and cross-training programs. The new finding, Kalev said, "means that companies can increase both quality and diversity at the same time, with the same programs." "Most women and minorities are stuck in low-visibility jobs with little opportunity for proving themselves and for advancement. When companies put in place cross-functional work teams and cross-training programs, these women and minorities suddenly have more opportunities to demonstrate their skills and smarts," Kalev said. Kalev, who has studied diversity programs extensively, analyzed 20 years of data on more than 800 companies and was able to isolate the effects of self-directed work teams and cross training programs on women"s and minorities" access to management. Other data reviewed include an extensive phone survey with managers in these companies and reports on workforce demographics that are sent each year to Washington. Kalev said more than 40 percent of American mid-sized and large employers have already adopted self-directed work teams and cross-training programs. Cross-functional teams are project groups where workers from different jobs meet frequently and take responsibility for getting the work done and solving problems. In cross training, Kalev explains, workers learn various jobs so they can perform their own job better or help others when needed. Women and minorities in these programs meet new people, participate and express their views, get responsibility and show managers that they can handle other duties. Teams and cross training, she added, put talented women and minorities on the radar screen of managers and others who get to know them better and can mentor them and mention their names when there is a new opening. Kalev points out that organizational psychologists have claimed for decades that stereotypes and prejudices will be counteracted if men and women, or whites and minorities, collaborate by working together as peers, rather than in functionally segregated, highly divided, work settings. "Most workplaces have historically been organized in this segregated way, but companies are now adopting teamwork and cross training as ways to motivate workers and increase efficiency and quality," Kalev said. It turns out these same programs also give new opportunities for women and minorities to shine and get ahead. Kalev"s work was funded by the National Science Foundation and the Robert Wood Johnson Scholars in Health Policy Research Program. Johnny Cruz University of Arizona
