Edward Dale, a 2010 Knox College graduate, has been awarded a prestigious National Science Foundation Graduate Research Fellowship, which recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines.
As a fellow, he will receive a three-year annual stipend of $30,000, a $12,000 cost-of-education allowance for tuition and fees, and opportunities for international research and professional development. He and other fellows also have the freedom to conduct their own research at any accredited U.S. institution of graduate education.
NSF received more than 13,000 applications for the 2013 competition. Fellowships were offered to 2,000 individuals.
Dale (in photo above with Knox Professor of Chemistry Diana Cermak, and in photo below at one of Knox College's traditional robot competitions) graduated summa cum laude from Knox, double-majoring inchemistry andbiochemistry and earningCollege Honors for his research project, "Synthesis of Optically Active -Aminophosphonic Acids." He was elected toPhi Beta Kappa as a junior and received the 2010 Harris Award in Chemistry.
Now a graduate student at Northwestern University, Dale is pursuing various molecular research projects. He briefly described a couple of them:
A native of Roscoe, Illinois, Dale said his childhood toys and a love for puzzles led him to this sort of research. "The first article I read related to this area was actually for a short literature review for [Knox Associate Professor of Chemistry Thomas Clayton's] inorganic chemistry class," he said, remembering that he was "immediately hooked."
Being a student at Knox "shaped me in so many ways," said Dale, who co-authored a Journal of Chemical Crystallography article with Clayton and three other collaborators. "Knox was an environment that opened new ideas and ways of thinking to me."
"I really owe a lot to the faculty at Knox," he added. (Photo at left: Edward Dale and his wife, Natalie.)
The influence of Professor of ChemistryDiana Cermak "helped alter my trajectory from medical school (which I now know would have been a mistake) toward graduate school and ignited a passion for research that I didn't know existed through theMcNair Fellowship and an Honors Project."

Some clever biochemistry has led to the worlds first enzyme-based memory capable of learning, say biochemists
Electronic processors are highly efficient at certain types of computation. For example, a standard PC can vastly outperform any human at arithmetic. However, computer scientists have long been fascinated by the ability of biological systems to do tasks, such as face recognition, at speeds and a power efficiency that put the most powerful supercomputers to shame.
Clearly, biology is able of computing in ways that traditional processors have failed to capture, which is why there is a significant interest in unconventional methods of computing that explore new ways of processing information.
One form of unconventional computing is biochemical and involves using molecules to encode information and using chemical reactions to process it. Nature has developed highly complex machinery for doing this so much of the focus has been on exploiting biological molecules for this task, using proteins, DNA and the like.
Today,Vera Bocharova and a few pals at Clarkson University in Potsdam, New York, say they ve used a set of enzymes to create a memory system that can learn to produce a specific output given a certain input. They says this system can even unlearn again later. We report the first realization of a simple variant of associative memory in an enzymaticbiochemical process, they say.
The theory is straightforward. Imagine the system as a black box that can have two chemical inputs and a chemical output. This output is a chemical called oxidised3,3,5,5-tetramethylbenzidine (TMB).
The black box produces oxidised TMB when it receives input 1 but the goal is to make it produce oxidised TMB when it receives input 2. In other words, Bocharova and co aim to teach the system to produce oxidised TMB when it senses input 2.
The trick theyve perfected is one of chemistry. Input 1 alone produces oxidised TMB. But Bocharova and co have designed the chemistry so that when input 1 and 2 are added together, the result is a chemical environment that is ripe for the production of oxidised TMBbut only when they add more of input 2.
So having added input 1 and 2 togetherhaving trained the systemit is now ready to produce oxidised TMB when it receives input 2 alone. The system has learned to respond to input 2.

A company contracted by US space agency Nasa to deliver supplies to the International Space Station has launched its first test rocket.
High winds forced Orbital Sciences Corporation to scrap the launch of the unmanned Antares rocket from Virginia on Saturday, but a new attempt was made on Sunday.
It blasted off from Wallops Island on Virginia's Eastern Shore.
About 10 minutes after the launch, Orbital Sciences declared the test a success after observing a practice payload reach orbit and safely separate from the rocket.
Nasa administrator Charles Bolden said in a statement: "Congratulations to Orbital Sciences and the Nasa team that worked alongside them for the picture-perfect launch of the Antares rocket.
"In addition to providing further evidence that our strategic space exploration plan is moving forward, this test also inaugurates America's newest spaceport capable of launching to the space station, opening up additional opportunities for commercial and government users."
The Antares rocket, which is an expendable launch system, is designed to put payloads weighing up to 5,000 kg (11,000 lb) into low-Earth orbit.
Orbital intends to use the Antares to launch its Cygnus spacecraft on the ISS resupply missions.
The Antares rocket was known during early development as the Taurus II, but was renamed in 2011 after the star of the same name.
Orbital now plans to launch another Antares carrying a Cygnus spacecraft in June.

Washington, Apr 23 : Three smartphones destined to become low-cost satellites rode to space Sunday aboard the maiden flight of Orbital Science Corp.'s Antares rocket from NASA's Wallops Island Flight Facility in Virginia.
The trio of "PhoneSats" is operating in orbit, and may prove to be the lowest-cost satellites ever flown in space. The goal of NASA's PhoneSat mission is to determine whether a consumer-grade smartphone can be used as the main flight avionics of a capable, yet very inexpensive, satellite.
Transmissions from all three PhoneSats have been received at multiple ground stations on Earth, indicating they are operating normally. The PhoneSat team at the Ames Research Center in Moffett Field, Calif., will continue to monitor the satellites in the coming days. The satellites are expected to remain in orbit for as long as two weeks.
"It's always great to see a space technology mission make it to orbit -- the high frontier is the ultimate testing ground for new and innovative space technologies of the future," said Michael Gazarik, NASA's associate administrator for space technology in Washington.
"Smartphones offer a wealth of potential capabilities for flying small, low-cost, powerful satellites for atmospheric or Earth science, communications, or other space-born applications. They also may open space to a whole new generation of commercial, academic and citizen-space users."
Satellites consisting mainly of the smartphones will send information about their health via radio back to Earth in an effort to demonstrate they can work as satellites in space.
The spacecraft also will attempt to take pictures of Earth using their cameras. Amateur radio operators around the world can participate in the mission by monitoring transmissions and retrieving image data from the three satellites.
Large images will be transmitted in small chunks and will be reconstructed through a distributed ground station network.
NASA's off-the-shelf PhoneSats already have many of the systems needed for a satellite, including fast processors, versatile operating systems, multiple miniature sensors, high-resolution cameras, GPS receivers and several radios.

Airborne imaging technology developed by NASA and transferred to the U.S. Department of Agriculture's Forest Service (USFS) in 2012 is being tested to prepare for this year's wildfire season in the western United States.
The Autonomous Modular Sensor (AMS) is a scanning spectrometer designed to help detect hot-spots, active fires, and smoldering and post-fire conditions. Scientists at NASA's Ames Research Center in Moffett Field, CA, and USFS engineers installed it on a Cessna Citation aircraft that belongs to the Forest Service. The USFS plans to use it in operational fire imaging and measurement.
The western United States is expected to have continued droughts this year resulting in increased potential for fire outbreaks, according to the National Interagency Fire Center (NIFC) in Boise, Idaho. To help mitigate fire danger, NASA researchers and USFS firefighters are collaborating to improve fire management capabilities.
"NASA technologies in the fields of data communication, aircraft systems, advanced sensing systems and real-time information processing finally have coalesced into the operational use that supports national needs in wildfire management," said Vincent Ambrosia, principal investigator of the Wildfire Research and Applications Partnership project and a senior research scientist at Ames and California State University, Monterey Bay.
Developed by NASA's Airborne Sciences Program, the Autonomous Modular Sensor acquires high-resolution imagery of the Earth's features from its vantage point aboard research aircraft. The sensor transmits nearly real-time data to ground disaster management investigators for analysis. The sensor has been modified to fly on various crewed and uncrewed platforms, including NASA's Ikhana remotely piloted aircraft, a Predator-B modified to conduct airborne research. Between 2006 and 2010 the AMS flew on the Ikhana and NASA's B-200 King Air (pictured) to demonstrate sensor capabilities, support national and state emergency requests for wildfire data, and ensure its operational readiness.
Data gathered during those flights was used to develop and test algorithms for scientific programs that monitor changes in environmental conditions, assess global change and respond to natural disasters.
The Autonomous Modular Sensor will be operated daily over wildfires throughout the United States, providing an unprecedented amount of data to the fire research and applications communities. USFS also will use the sensor to support other agency objectives, such as vegetation inventory analysis and water and river mapping.
"I see tremendous opportunity for my agency and other land management agencies to benefit from the application of NASA-developed technology," said Everett Hinkley, national remote sensing program manager with USFS in Arlington, Va. "The AMS expands our current capabilities and offers efficiencies in a number of remote-sensing applications including fire, post-fire and forest health applications."

WALLOPS ISLAND, Va., April 22 (UPI) -- A U.S. commercial partner of NASA launched a rocket into space carrying a so-called mass simulated payload.
NASA said the launch of Orbital Sciences Corporation's Antares rocket and payload from a flight facility in Virginia Sunday was part of the effort to rely on U.S. companies for future launches of supplies and personnel to the International Space Station.
"Today's successful test marks another significant milestone in NASA's plan to rely on American companies to launch supplies and astronauts to the International Space Station, bringing this important work back to the United States where it belongs," said NASA Administrator Charles Bolden.
"Congratulations to Orbital Sciences and the NASA team that worked alongside them for the picture-perfect launch of the Antares rocket.
"In addition to providing further evidence that our strategic space exploration plan is moving forward, this test also inaugurates America's newest spaceport capable of launching to the space station, opening up additional opportunities for commercial and government users."
The completed flight paves the way for a demonstration mission by Orbital to resupply the space station later this year, NASA said.

NASA's off-the-shelf PhoneSats already have many of the systems needed for a satellite, including fast processors, versatile operating systems, multiple miniature sensors, high-resolution cameras, GPS receivers and several radios.
NASA engineers kept the total cost of the components for the three prototype satellites in the PhoneSat project between $3,500 and $7,000 by using primarily commercial hardware and keeping the design and mission objectives to a minimum. The hardware for this mission is the Google-HTC Nexus One smartphone running the Android operating system.
NASA added items a satellite needs that the smartphones do not have -- a larger, external lithium-ion battery bank and a more powerful radio for messages it sends from space. The smartphone's ability to send and receive calls and text messages has been disabled. Each smartphone is housed in a standard cubesat structure, measuring about 4 inches square. The smartphone acts as the satellite's onboard computer. Its sensors are used for attitude determination and its camera for Earth observation.

Wallops Island, Virginia, Apr 22 : NASA commercial space partner Orbital Sciences Corporation Sunday launched its Antares rocket at 5 p.m. EDT from the new Mid-Atlantic Regional Spaceport Pad-0A at the agency's Wallops Flight Facility in Virginia.
The test flight was the first launch from the pad at Wallops and was the first flight of Antares, which delivered the equivalent mass of a spacecraft, a so-called mass simulated payload, into Earth's orbit.
"Today's successful test marks another significant milestone in NASA's plan to rely on American companies to launch supplies and astronauts to the International Space Station, bringing this important work back to the United States where it belongs," said NASA Administrator Charles Bolden.
"Congratulations to Orbital Sciences and the NASA team that worked alongside them for the picture-perfect launch of the Antares rocket. In addition to providing further evidence that our strategic space exploration plan is moving forward, this test also inaugurates America's newest spaceport capable of launching to the space station, opening up additional opportunities for commercial and government users.
"President Obama has presented a budget for next year that ensures the United States will remain the world leader in space exploration, and a critical part of this budget is the funding needed to advance NASA's commercial space initiative. In order to stop outsourcing American space launches, we need to have the President's budget enacted. It's a budget that's good for our economy, good for the U.S. Space program -- and good for American taxpayers."
The test of the Antares launch system began with the rocket's rollout and placement on the launch pad April 6, and culminated with the separation of the mass simulator payload from the rocket.
The completed flight paves the way for a demonstration mission by Orbital to resupply the space station later this year. Antares will launch experiments and supplies to the orbiting laboratory carried aboard the company's new Cygnus cargo spacecraft through NASA's Commercial Resupply Services (CRS) contract.
"Today's successful test flight of Orbital Sciences' Antares rocket from the spaceport at Wallops Island, Virginia, demonstrates an additional private space-launch capability for the United States and lays the groundwork for the first Antares cargo mission to the International Space Station later this year," said John Holdren, director of the Office of Science and Technology Policy.
"The growing potential of America's commercial space industry and NASA's use of public-private partnerships are central to President Obama's strategy to ensure U.S. leadership in space exploration while pushing the bounds of scientific discovery and innovation in the 21st century. With NASA focusing on the challenging and exciting task of sending humans deeper into space than ever before, private companies will be crucial in taking the baton for American cargo and crew launches into low-Earth orbit.

The annual Lyrid meteor shower may have peaked overnight on Sunday and Monday, but if you missed the celestial fireworks show don't fret. NASA's got you covered.
Scientists at NASA's Marshall Space Flight Center (MSFC) in Huntsville, Ala., will broadcast live images of the Lyrid meteor shower tonight and early Tuesday (April 22 and 23) for stargazers stuck with bad weather or light-polluted night skies.
The NASA broadcast will begin at 8:30 p.m. EDT (0030 April 23) and run throughout the evening. You can watch the Lyrid meteor shower webcast on SPACE.com courtesy of NASA's MSFC feed.
"If you'd like to catch a last look at 2013 Lyrid meteor shower, this is your chance!" MSFC officials said in an announcement today. "Although a bright moon may interfere with viewing, you should still be able to see Lyrid meteors at an anticipated rate of 10-20 meteors per hour."
This year, the Lyrid meteor display runs from April 16 through April 26, though it peaked overnight on April 21 and 22. Because the moon is bright in the evening sky, the best time to look for the Lyrids is in the wee morning hours before dawn, after the moon has set but before the sun rises.
The Lyrid meteor shower occurs each year in mid-April when the Earth passes through a dusty lane of debris left over from Comet Thatcher, which is also known as C/1861 G1 Thatcher. The comet orbits the sun once every 415 years. The Lyrids are created when the comet's dust streaks through Earth's atmosphere at speeds of up to 110,000 mph (177,027 kph).
The Lyrids get their name because they appear to radiate out of the constellation Lyra. Humans have been observing the "shooting stars" display for more than 2,600 years, NASA scientists have said.
