Scientists have succeeded for the first time in making, out of DNA double stands, an interlocked molecule (rotaxane) with freely moveable components. This opens up exciting possibilities for nanorobotics and synthetic biology.
The application of nanotechnology will have a major influence in many fields of medicine. Novel nano-based materials appear in drug delivery systems, diagnostics, imaging, biosensing, and medical materials and devices.
Forget what you know about how diseases are diagnosed. New research details a noninvasive ground-breaking tool that detects signs of disease at early molecular stages before symptoms can be seen using traditional methods.
As the pace of changing technology quickens, a robust and open national capability for technology assessment - the process of estimating the broad social, ethical, legal and economic impacts of emerging science and technology - is critical and must include public participation to complement expert analysis, says a new report, 'Reinventing Technology Assessment: A 21st Century Model'.
'Hot sounds' has one meaning to music fans and another to physicists. Count a team of researchers at Rice University among the latter, as they've discovered that acoustic waves traveling along ribbons of graphene might be just the ticket for removing heat from very tiny electronic devices.
The U.S. Army Research Office (ARO) together with the National Security Agency (NSA) is soliciting proposals for basic and applied research to advance quantum computing technology. Research areas of particular interest include: 1) Robust Solid-State Qubits and Related Technologies; 2) Quantum Information Transfer; 3) Verification/Validation and Analysis of Quantum Computing Components.
