Marine science majors conduct field research with horseshoe crab census
Wearing sneakers and rain boots, University of Delaware freshmen got their feet wet as marine biologists recently while counting horseshoe crabs along the Delaware Bay. The students participated in a monitoring effort to gain firsthand experience in field research with their fellow marine science majors.
“Where else can you go on a Saturday night to count horseshoe crabs?” freshman Will Goldman said. (more…)
For two molecules on blind date, new method predicts potential for attraction or repulsion
Krzysztof Szalewicz, professor of physics and astronomy at the University of Delaware, and Rafal Podeszwa of the University of Silesia Institute of Chemistry in Poland have developed and validated a more accurate method for predicting the interaction energy of large molecules, such as biomolecules used to develop new drugs.
The research is reported as a communication in the April 27 issue of the Journal of Chemical Physics, which is the most highly cited journal in atomic, molecular and chemical physics according to Thomson Reuters. The journal is published by the American Institute of Physics. Despite appearing at the end of April, the paper was on the list of the 20 most-read articles in JCP for that month. (more…)
Renowned expert Charles J. Vörösmarty addresses global water crisis
The world’s streams, rivers and lakes are under increasing stress because of human water management – and mismanagement – that threaten aquatic biodiversity and the water supply, Charles J. Vörösmarty said recently during the second annual John R. Mather Visiting Scholars Lecture.
Vörösmarty, professor of civil engineering with the City College of New York, presented “Global Water Crisis: The Slippery Slope” on May 3 at the University of Delaware’s Roselle Center for the Arts.
“The contemporary water system is really defined increasingly by the actions of humans,” he said. (more…)
T3D goes beyond Hen Hatch, places among top collegiate startups worldwide
T3D Nanotech, LLC, a high technology startup company spun off from patent pending nanotech research at the University of Delaware, was recently awarded $1,000 in UD’s Hen Hatch competition. But that award was preceded by another honor: selection to participate in the 2012 Rice Business Plan Competition (RBPC).
As the world’s largest and richest business plan competition, the RBPC supports the creation of new startup companies and brings together business and engineering students from the world’s top educational institutions with successful venture capital investors, entrepreneurs and business leaders.
Out of a pool of 1,600 applicants, T3D gained entry to the top 2.6 percent of just 42 teams invited to compete for more than $1.5 million in prizes. (more…)
Intelligence historian cites changing focus of American espionage
In the spy trade, predicting the future is a risky business at best, but experts believe that America’s intelligence efforts will focus on Iran, North Korea and China.
Matthew M. Aid, intelligence historian and expert on the National Security Agency, discussed the forces driving this emerging strategy during a talk on Wednesday, May 2, in Mitchell Hall.
Aid’s talk, “The Future of Intelligence and Espionage,” concluded the spring 2012 Global Agenda speaker series “Spies, Lies and Sneaky Guys: Espionage and Intelligence in the Digital Age.” (more…)
Wind pushes plastics deeper into oceans, driving trash estimates up
Decades of research into how much plastic litters the sea may have only skimmed the surface. A new study reveals that wind drives confetti-sized pieces of plastic debris deeper underwater than previously believed, more than doubling earlier estimates of the pollutant’s presence in oceans.
“In windy conditions the traditional approach to measuring plastic marine debris captures only a small fraction of plastic pieces,” said Tobias Kukulka, assistant professor of physical ocean science and engineering in the University of Delaware’s College of Earth, Ocean, and Environment. “Our study helps to better understand how much plastic there is and where, as well as the complexity of the ocean dynamics at work.” (more…)
For treatment of vocal fold disorders, UD researchers look to insect protein
A one-inch long grasshopper can leap a distance of about 20 inches. Cicadas can produce sound at about the same frequency as radio waves. Fleas measuring only millimeters can jump an astonishing 100 times their height in microseconds. How do they do it? They make use of a naturally occurring protein called resilin.
Resilin is a protein in the composite structures found in the leg and wing joints, and sound producing organs of insects. Highly elastic, it responds to exceptionally high rates of speed and demonstrates unmatched resilience after being stretched or deformed. (more…)
Massive detector homes in on cosmic ray production
IceCube, an international collaboration involving University of Delaware scientists, is shedding new light on cosmic ray production.
Although cosmic rays were discovered 100 years ago, their origin remains one of the most enduring mysteries in physics. Now, the IceCube Neutrino Observatory, a massive detector in Antarctica, is homing in on how the highest energy cosmic rays are produced. (more…)
