Has Voyager 1 left the Solar System? Is it officially the first spacecraft to reach interstellar space? It depends on whom you ask. NASA says no, but W.R. Webber of the New Mexico State University Department of Astronomy and F.B. McDonald of the University of Maryland Institute of Physical Science and Technology say yes. They contend that the unmanned, nuclear-powered probe left the Solar System on August 25, 2012 at a distance of 121.7 AU (18.2 billion km) from the Sun when its instruments on board detected a major shift in cosmic ray intensity.  Read More

The Gamera II team have broken the 60-second flight barrier and reached an altitude of ove...

The Gamera II team at the A. James Clark School of Engineering has certainly been keeping officials at the National Aeronautic Association (NAA) very busy this year. Kyle Gluesenkamp from the school's mechanical engineering department pedaled and cranked his way into the record books in June with a new official national record for human-powered helicopter flight with a time of 49.9 seconds, and now that too has been smashed. A new venue, and some vital modifications to the huge craft has resulted in the magic Sikorsky Prize 60-second barrier being surpassed for the very first time. Not only that, but Gamera II has also been taken up beyond eight feet before a serious crash landing put a stop to more record attempts.  Read More

The unofficial human-powered helicopter flight record set by Kyle Gluesenkamp from the A. James Clark School of Engineering's Gamera II team on June 21 2012 has just been ratified by the National Aeronautic Association (NAA). The new national record has now been submitted to the Fédération Aéronautique Internationale for approval as a new world record.  Read More

For over 30 years, the US$250,000 cash prize for the American Helicopter Society's Igor I. Sikorsky Human Powered Helicopter Competition prize has looked decidedly secure, but Gamera II has changed all that. Last week, Clark School of Engineering team pilots came so close to breaking one of the competition's major milestones that they could virtually smell it. Ph.D. candidate from Kyle Gluesenkamp from the School's mechanical engineering department, hand-cranking and pedaling like his life depended on it, managed to keep the huge quad-rotor craft aloft for 50 seconds, an impressive new world record that's currently awaiting validation by the National Aeronautic Association (NAA).  Read More

Last July, the frantic pumping of upper and lower limbs of intrepid pilot Judy Wexler managed to keep the huge Gamera human-powered helicopter in the air for a record-breaking 11.4 seconds. The student team from the Alfred Gessow Rotorcraft Center at the University of Maryland's Department of Aerospace Engineering has since been busy refining and redesigning the craft for another stab at the elusive US$250,000 American Helicopter Society's Sikorsky Prize. Gamera II has been built for longer flight duration and is lighter and tougher than its predecessor, with improved transmission and enhanced rotor design. The new x-shaped craft is set to take off next week for its first test runs and the team is confident that existing record times will be smashed... but will it nab the ultimate prize?  Read More

A close-up view of the microlenses making up the biochip array

When we think of invisibility cloaks, probably the first things that come to mind are Harry Potter-like contraptions that allow people or large objects to instantly disappear. Scientists from the University of Maryland and nearby Towson University, however, today announced their development of something a little different – little being the key word. They have crammed 25,000 tiny “invisibility cloaks” onto a gold sheet, which itself only measures 25 millimeters per side. While the resulting biochip array may not allow any young wizards to vanish from sight, it could allow them to identify biological materials.  Read More

Newly-developed cavity-filling substances could lead to fillings that last much longer

When a dentist drills out the decayed section of a tooth that has a cavity, it’s important that they also remove the bacteria that caused the decay in the first place – or at least, that they remove as much of it as possible. If they don’t, the bacteria can get reestablished, causing the filling to fail. Now, scientists from the University of Maryland’s School of Dentistry have developed a new cavity-filling system that they say will not only kill virtually all residual bacteria, but also help the tooth to regrow some of the tissue that was lost to decay.  Read More

Remarkable transformation - before and after shots of the face transplant recipient (Photo...

A gun accident fifteen years ago left Richard Lee Norris without his lips, nose, and with limited movement of his mouth. Now after a marathon 36-hour surgical procedure described as "the most extensive full face transplant completed to date," a team led by Dr. Eduardo Rodriguez at the University of Maryland has restored Mr. Norris' quality of life.  Read More

On the last two occasions, the overall winner of the U.S. Department of Energy Solar Decathlon has gone to Germany's Technische Universität Darmstadt but this year the top honor has stayed with one of the home teams. As the name might suggest, the University of Maryland's winning WaterShed project features some novel innovations to make the best use of water, in addition to an intriguing internal waterfall that helps reduce the load on the structure's air conditioning system. Read on for a brief look at the top five winning projects, as well as the People's Choice.  Read More

Hovering for 11.4 seconds has secured a place in the record books for the Gamera team, and...

A biology student has just hovered her way into the record books in a four-rotor, human-powered helicopter named after a giant flying turtle from Japanese kaiju movies. Gamera was built to try and claim the American Helicopter Society's Sikorsky Prize, that was set up in 1980 and has yet to be claimed. The team's first flights in May resulted in a 4.2-second U.S. national record, and now the record page has had to be rewritten again after the young pilot's frantic combination of hand and foot pedaling action kept Gamera in the air for nearly three times longer, during the recent summer flight sessions.  Read More
