"Our Aware-2 camera combines 98 small cameras with a spherical lens to take black-and-white gigapixel photographs. It set the record for the largest digital snapshot by a terrestrial camera. One image from the camera, printed at 300 dots per inch, is 8 feet high by 16 feet long.
Silicon chips are on the way out, at least if Duke University engineer Chris Dwyer has his way. The professor of electrical and computer engineering says a single grad student using the unique properties of DNA to coax circuits into assembling themselves could produce more logic circuits in a single day than the entire global silicon chip industry could produce in a month.
They say only time heals a broken heart, but Duke University researchers think they can do better. Using embryonic stem cells from mice and their own novel molding technique, a team of researchers at Duke has developed a three-dimensional heart cell "patch" that conducts electrical impulses and contracts, two all important characteristics of heart tissue.
Ghosts, poltergeists, and telepathy, oh my! Can these phenomena be explained by science? A group of researchers at the Duke Parapsychology Laboratory believed so and strove to explain the unexplainable. Plus, a PopSci Giveaway!
During the early 1930s, Duke University went against the grain and opened a parapsychology lab. J.B. Rhine, who actually coined the term parapsychology, along with his colleagues sought to uncover the truth about various phenomena using scientific methods. In Unbelievable, author Stacy Horn chronicles the decades of research done in the lab.
PopSci.com's Catherine Schwanke recently spoke with Horn by phone to discuss her new book, and the unbelievable.
Plus: Got a question for Stacy Horn? Ask away! We've devoted a forum to your queries here. Ms. Horn will answer as many of your questions as possible, also in the forum, during the week of March 22-27.Feeling lucky? Leave a comment (any comment) below.

Lets hope this isnt another false accusation, delivered before the verdict is in. A Duke University spokesman says the college has been working with Apple in preparation for the start of the school year, because that companys new iPhones have supposedly frozen parts of the schools wireless network for up to ten minutes at a time. Apparently a single iPhone requesting access to the network was enough to stall parts of the system, and there are already as many as 150 of the devices trying to get online. Administrators noticed the problem nine times in the last week alone. Now the network team is trying to fix the glitch before the full student body returns for classes next week. But the bigger question, to us: Who is buying all these kids iPhones? Yes, they are bright students, but how in the name of Jobs are they convincing their parents to pay $2,000 a year for their phones? Theres a good explanation of the possible network issues, but not the spoiled student problem, here.—Gregory Mone
In our October issue, we reported on the theoretical and practical work being done to make the fantasy of invisibility a reality [read the article online here]. Yesterday one of those teams of researchers—a Duke University group led by David Smith—announced that they had demonstrated the worlds first working invisibility cloak. And unlike other cloaks, which use images projected onto the surface of the item to be hidden, Smiths actually bends light around the object, making the light behave as if the object isnt even there.
The cloak, which is less than five inches long, is a synthetic structure composed of copper rings and wires placed onto sheets of fiberglass. Its applicability is limited: It works for only two dimensions and only against a microwave beam. The technology to create an invisibility cloak for regular light, which is made of many different wavelengths, is still decades away. See a video of the new cloak here. —Abby Seiff
With about 60 percent of Americans officially fat, there's plenty of blame to go around. Scientists at Duke University have just found another factor to join the ranks of trans fats and fast food: your mother. Tweaking the diet of pregnant mice had a substantial influence on their offspring's gene expression—specifically, the expression of a gene responsible for obesity. And adding a soy isoflavone to the mothers' diets during pregnancy limited the expression of the gene in utero, leading to babies half the weight of their soy-starved counterparts. But keep your maternal grudge in check: The human variant of the gene doesn't seem to be susceptible to the benefits of prenatal soy. —Eric Mika
