Precise Reading

Noise and vibration can generate inaccurate readings in precision systems such as planetarium astronomy equipment, parabolic antennas and laser based guidance systems that rely on precise pointing to receive or transmit signals. The sources of this problem, commonly called jitter, can range from [...]

High-Intensity Ultrasound May Launch an Attack on Cancer, Wherever it Lurks

An intense form of ultrasound that shakes a tumor until its cells start to leak can trigger an “alarm” that enlists immune defenses against the cancerous invasion, according to a study led by researchers at Duke University's Pratt School of Engineering. The new findings from animal experiments [...]

Automated Technique Paves Way for Nanotechnology’s Industrial Revolution

In an assist in the quest for ever smaller electronic devices, Duke University engineers have adapted a decades-old computer aided design and manufacturing process to reproduce nanosize structures with features on the order of single molecules. The new automated technique for nanomanufacturing [...]

Unraveling the Physics of DNA's Double Helix

Researchers at Duke University's Pratt School of Engineering have uncovered a missing link in scientists' understanding of the physical forces that give DNA its famous double helix shape. "The stability of DNA is so fundamental to life that it's important to understand all factors," said Piotr [...]

Theory of Physics Applies to Human Migration, Air Traffic Control and Corporate Sustainability

DURHAM, N.C. -- Why does a railway network look like a river? Why do the streets of old Rome look like a leaf? Because whether their shape is determined by the interactions of molecules or the choices made by individual humans, all of these systems of flow are governed by a relatively simple new [...]

Making 'Smarter' Use of 'Smart' Gels

Once considered something of a laboratory novelty, ‘smart’ gels -- synthesized from polymers that can undergo dramatic transformations in response to changes in their surroundings -- are now poised to become integral mechanical components and sensors in the increasingly tiny devices of the future. [...]
