Looking into the interior of the Earth or the Sun is a bit similar to examining a baby in its mother`s womb using an ultrasound scan. Light cannot penetrate the area, so we make pictures in these cases using sound waves, which human ears cannot hear. With SOHO, ESA has probed deeply into the Sun using the sound-waves principle, and with great success. The future missions, Solar Orbiter and Eddington, will look inside our Sun and other stars, respectively, in a similar way.
Here on Earth, whe
A new laser procedure that requires only local anesthetic is effective in treating nasal passageway obstructions associated with a deviated nasal septum, according to an article in the July-September issue of The Archives of Facial Plastic Surgery, one of the JAMA/Archives journals. The procedure uses heat generated by a laser to soften cartilage abnormalities so that they can be flattened or shaped to clear the nasal passages.
The septum is the cartilage wall that divides and separates the
Researchers at Oxford University’s Physics Department have developed an extraordinarily versatile proximity sensor for the detection of objects, composed of ferrous and non-ferrous metals, ceramics, glasses and plastics. This new device could be used as a position or speed sensor in automotive suspension, gearbox and engine management systems, amongst many other uses.
Researchers had identified the need for a relatively simple, but highly versatile proximity sensor to detect the motion of a
Something new and exciting found serendipitously
A compound that could potentially immobilize the AIDS virus or selectively extract radionuclides from nuclear wastes at various U.S.high-level storage sites has been developed by a researcher at Sandia National Laboratories who wasnt even looking for it.
An article in the current issue of Science describes characteristics of the newly discovered, extremely active compound, called niobium heteropolyanions (het
New research by economists at the University of Warwick reveals that men who smoke but who want a long life should marry without delay as marriage reduces the risk of death by even more than the act of smoking increases the risk of dying.
University of Warwick researchers Professor Andrew Oswald and Dr Jonathan Gardner examined the data from the British Household Panel survey – a nationally representative sample of over 5,000 British households containing over 10,000 adults who had been stu
Finding May Present a New Target for Anti-Cancer Drugs
Researchers at the Duke Comprehensive Cancer Center have found that a known cancer-causing gene, Ras, may exert its influence through very different pathways in humans than in mice, a finding that could offer tantalizing new targets for anti-cancer therapy.
While studying the Ras, gene, Duke researchers unexpectedly found that it activates an obscure group of proteins in humans, but not in mice, in order to turn normal c
