Researchers at the University of Nottingham have developed an ultrasonic imaging system, which can be deployed on the tip of a hair-thin optical fibre, and will be insertable into the human body to visualise cell abnormalities in 3D. The new technology produces microscopic and nanoscopic resolution images that will one day help clinicians to examine …
So-called “zero-point energy” is a term familiar to some cinema lovers or series fans; in the fictional world of animated films such as “The Incredibles” or the TV series “Stargate Atlantis”, it denotes a powerful and virtually inexhaustible energy source. Whether it could ever be used as such is arguable. Scientists at Jülich have now …
Japanese researchers demonstrated a gigapixel inline digital holographic microscopy using a consumer scanner. The consumer scanner can maximally scan an A4 size (European pagesize) image (297mm × 210mm) with 4800 dpi (≈ 5.29µm), theoretically achieving a resolution of 56,144 × 39,698 ≈ 2.22 gigapixels. The system using a consumer scanner has a simple structure, compared …
Eurekalert – Researchers from the University of Miami (UM) are unveiling a novel theoryfor high-temperature superconductivity. The team hopes the new finding gives insight into the process, and brings the scientific community closer to achieving superconductivity at higher temperatures than currently possible. This is a breakthrough that could transform our world. Superconductors are composed of …
Flux Capacitors and the Origin of Inertia (29 pages) The explanation of inertia based on “Mach’s principle” is briefly revisited and an experiment whereby the gravitational origin of inertia can be tested is described. The test consists of detecting a small stationary force with a sensitive force sensor. The force is presumably induced when a …
(a) Split ring resonator for high-frequency metamaterials (outer ring diameter is 2.26mm). (b) Spiral resonator for radio frequency metamaterials (outer diameter is 6mm and has 40 turns). Metamaterials (so called because of their engineered electromagnetic properties) hold great promise for new applications in the megahertz to terahertz bands, as well as optical frequencies. Examples including …
Bonn scientists discover a promising new approach to combat obesity Fighting fat with fat The researchers suspect that a disorder of the brown fatty tissue can lead to obesity in adults. If it were possible to turn on the ‘natural heating system’ on again, the problem of unwanted fat would be quickly solved: according to …
