Human-powered ornithopter becomes first ever to achieve sustained flight

2010-09-22
(Press-News.org) TORONTO, ON – Aviation history was made when the University of Toronto's human-powered aircraft with flapping wings became the first of its kind to fly continuously.

The "Snowbird" performed its record-breaking flight on August 2 at the Great Lakes Gliding Club in Tottenham, Ont., witnessed by the vice-president (Canada) of the Fédération Aéronautique Internationale (FAI), the world-governing body for air sports and aeronautical world records. The official record claim was filed this month, and the FAI is expected to confirm the ornithopter's world record at its meeting in October.

For centuries engineers have attempted such a feat, ever since Leonardo da Vinci sketched the first human-powered ornithopter in 1485.

But under the power and piloting of Todd Reichert, an Engineering PhD candidate at the University of Toronto Institute for Aerospace Studies (UTIAS), the wing-flapping device sustained both altitude and airspeed for 19.3 seconds, and covered a distance of 145 metres at an average speed of 25.6 kilometres per hour.

"The Snowbird represents the completion of an age-old aeronautical dream," says lead developer and project manager Reichert. "Throughout history, countless men and women have dreamt of flying like a bird under their own power, and hundreds, if not thousands have attempted to achieve it. This represents one of the last of the aviation firsts."

The Snowbird weighs just 94 lbs. and has a wing span of 32 metres (105 feet). Although its wingspan is comparable to that of a Boeing 737, the Snowbird weighs less than all of the pillows on board. Pilot Reichert lost 18 lbs. of body weight this past summer to facilitate flying the aircraft.

With sustainability in mind, Aerospace Engineering graduate students of UTIAS learned to design and build lightweight and efficient structures. The research also promoted "the use of the human body and spirit," says Reichert.

"The use of human power, when walking or cycling, is an efficient, reliable, healthy and sustainable form of transportation. Though the aircraft is not a practical method of transport, it is also meant to act as an inspiration to others to use the strength of their body and the creativity of their mind to follow their dreams."

The Snowbird development team is comprised of two University of Toronto Engineering graduate students: Reichert, and Cameron Robertson (MASc 2009) as the chief structural engineer; UTIAS Professor Emeritus James D. DeLaurier as faculty advisor; and community volunteers Robert and Carson Dueck. More than 20 students from the University of Toronto and up to 10 exchange students from Poitiers University, France, and Delft Technical University, Netherlands, also participated in the project.

"This achievement is the direct result of Todd Reichert's dedication, perseverance, and ability and adds to the already considerable legacy of Jim DeLaurier, UTIAS's great ornithopter pioneer," said Professor David Zingg, Director of UTIAS. "It also reflects well on the rigorous education Todd received at the University of Toronto. We're very proud of Todd and the entire team for this outstanding achievement in aviation history."

INFORMATION: A photo opportunity for journalists, with the ornithopter on display, will be held tomorrow, Thursday, September 23rd at 1 p.m. at the Great Lakes Gliding Club in Tottenham, Ontario. RSVP to Elizabeth Raymer by Thursday at 10 a.m., and to receive directions.

Humanized mice may provide clues to better prevent and treat typhoid fever
2010-09-22
Better treatments and prevention for typhoid fever may emerge from a laboratory model that has just been developed for the disease. The model is based on transplanting human immune stem cells from umbilical cord blood into mice that are susceptible to infections. The transplanted cells live alongside the mouse's own immune system. Although mice are normally resistant to the dangerous strain of Salmonella that causes typhoid fever, the bacteria are able to reproduce in the mice that have received transplanted human cells. Because typhoid fever affects only humans, ...

Adjustments, applications and other tools allow users to configure preferences and use services such as iGoogle and Yahoo to control and customize the news they consume online. These tools can make online experiences more efficient and productive, but they do not ensure that users will be consistently pleased with their selections, according to Penn State researchers. "There is a major push toward customization in the marketplace because designers assume that more customization is better, but our research shows that only some users prefer customization," said S.

Losing your religion deemed unhealthy

2010-09-22
People who leave strict religious groups are more likely to say their health is worse than members who remain in the group, according to a Penn State researcher. The percentage of people who left a strict religious group and reported they were in excellent health was about half that of people who stayed in the group, said Christopher Scheitle, senior research assistant, in sociology. "Previous research showed some association between belonging to a religious group and positive health outcomes," Scheitle said. "We became interested in what would happen to your health ...

Gum disease found to be significant public health concern

2010-09-22
September 21, 2010 – Chicago – The prevalence of periodontal disease in the United States may be significantly higher than originally estimated. Research published in the Journal of Dental Research from the Centers for Disease Control and Prevention (CDC) and the American Academy of Periodontology (AAP) suggests that the prevalence of periodontal disease may have been underestimated by as much as 50 percent. The implication is that more American adults may suffer from moderate to severe gum disease than previously thought. In a National Health and Nutrition Examination ...

Study: Doctors overprescribe antibiotics for respiratory infections

2010-09-22
Doctors frequently misuse antibiotics when treating patients hospitalized with respiratory tract infections (RTIs), according to a study to be published in the November issue of Infection Control and Hospital Epidemiology. The study, which tracked patients in two Pennsylvania hospitals, found that doctors often use antibiotics to treat patients whose infections are known to be caused by viruses. The findings are alarming because antibiotics are not effective against viruses, and antibiotic overuse has been linked to the development of resistant bacterial strains. "[T]hese ...

Food for thought, er, well ...

2010-09-22
Ever wonder why it's such an effort to forget about work while on vacation or to silence that annoying song that's playing over and over in your head? Mathematicians at Case Western Reserve University may have part of the answer. They've found that just as thinking burns energy, stopping a thought burns energy - like stopping a truck on a downhill slope. "Maybe this explains why it is so tiring to relax and think about nothing," said Daniela Calvetti, professor of mathematics, and one of the authors of a new brain study. Their work is published in an advanced online ...

NASA study shows desert dust cuts Colorado River flow

2010-09-22
Snowmelt in the Colorado River basin is occurring earlier, reducing runoff and the amount of crucial water available downstream. A new study shows this is due to increased dust caused by human activities in the region during the past 150 years. The study, led by a NASA scientist and funded by the agency and the National Science Foundation, showed peak spring runoff now comes three weeks earlier than before the region was settled and soils were disturbed. Annual runoff is lower by more than five percent on average compared to pre-settlement levels. The findings have ...

Farm, forest lands being protected -- but not always for farming or forestry

2010-09-22
CORVALLIS, Ore. – More than 35 years after Oregon began one of the nation's most ambitious land use planning programs, a new study suggests it's still difficult to demonstrate that it has accomplished one of its primary goals – protecting agricultural lands and a thriving forest, farm and ranching industry. There's some evidence that the laws have provided a "measurable degree of protection," scientists say in the report. However, there are also impacts that were little anticipated or considered four decades ago, such as the growth of "hobby farms" in which farming or ...
