US Cyber Challenge puts UD student on fast track to outwitting hackers
“Cryptography enables you to send secret code and hide information within a network to keep it secure,” Billy Bednar, a University of Delaware senior, told U.S. Sen. Tom Carper during a conference call Wednesday, July 18.
Carper, who is chairman of the Senate Homeland Security and Governmental Affairs Committee, is working to help safeguard the nation’s cyber space. To accomplish this he will need to rely on today’s leading experts, but also ensure that future cyber sleuths currently in the pipeline have the proper training to meet emerging cyber challenges.

Through a shared commitment to STEM education, Microsoft and LEGO Education team up to create hands-on opportunities for the next generation to be inspired by and engage with technology in new ways.
SAN FRANCISCO — Ever wonder what it takes to inspire and prepare the next generation to fill the pipeline of science, technology, engineering and mathematics (STEM) jobs of the future? For Microsoft and LEGO, the answer is simple: Make STEM fun, accessible and engaging. At Microsoft’s recent developer conference, BUILD, Microsoft revealed the SentryBot — a small, yet powerful, robot featuring unique interactive scenarios only possible on the Windows platform. SentryBot demonstrates just how fun STEM can be regardless of your technical background.(more…)
There is only one planet we know of, so far, that is drenched with life. That planet is Earth, as you may have guessed, and it has all the right conditions for critters to thrive on its surface. Do other planets beyond our solar system, called exoplanets, also host life forms?
Astronomers still don’t know the answer, but they search for potentially habitable planets using a handful of criteria. Ideally, they want to find planets just like Earth, since we know without a doubt that life took root here. The hunt is on for planets about the size of Earth that orbit at just the right distance from their star – in a region termed the habitable zone. (more…)
Pollination, essential to much of life on earth, requires the explosive death of the male pollen tube in the female ovule. In new research, Brown University scientists describe the genetic and regulatory factors that compel the male’s role in the process. Finding a way to tweak that performance could expand crop cross-breeding possibilities.
PROVIDENCE, R.I. [Brown University] — Millions of times on a spring day there is a dramatic biomolecular tango where the flower, rather than adorning a dancer’s teeth, is the performer. In this dance, the female pistil leads, the male pollen tubes follow, and at the finish, the tubes explode and die. A new paper in Current Biology describes the genetically prescribed dance steps of the pollen tube and how their expression destines the tube for self-sacrifice, allowing flowering plants to reproduce.

Even as the dinosaurs were becoming extinct 66 million years ago, the ancient ancestor of spiny-rayed fishes flourished, eventually giving rise to tens of thousands of species that can now be found in home aquariums or on dinner plates. Using modern genetic tools and information from the fossil record, a team led by researchers at Yale University, University of Oxford, and University of California-Davis have constructed a detailed evolutionary history of the 18,000 species of spiny-rayed fishes existing today, a diverse group that includes basses, pufferfishes, and cichlids, and that comprises a large portion of the vertebrate tree of life.
The findings published the week of July 15 in the Proceedings of the National Academy of Sciences show surprisingly close evolutionary relationships between lineages of fish species such as tunas and seahorses, and suggest some fish lineages — like cichlids, the tiny gobies, and little-studied snailfishes — are experiencing high rates of new species origination.

AUSTIN, Texas — A team of U.S. and U.K. scientists has found geologic evidence that casts doubt on one of the conventional explanations for how Antarctica’s ice sheet began forming. Ian Dalziel, research professor at The University of Texas at Austin’s Institute for Geophysics and professor in the Jackson School of Geosciences, and his colleagues report the findings today in an online edition of the journal Geology.(more…)
Dozens of atmospheric scientists, including three University of Washington faculty members, are taking part in what’s being described as one of the largest atmospheric field campaigns in decades.
The six-week Southeast Atmosphere Study, through July 15, includes scientists from more than 30 different institutions. Together they are studying how pollutants combine with natural vegetation emissions to affect climate and air quality in the Southeastern U.S. (more…)
