U.K. scientists say they have solved one of the most puzzling features of the sun: why its outside atmosphere is hotter than its inner photosphere. Researchers from Belfast's Queen's University and Britain's University of Sheffield said the surface of the sun, known as the photosphere, reaches temperatures of 5,000 degrees Celsius, while its outer atmosphere, known as the corona, can reach temperatures of more than 1 million degrees Celsius. The scientists discovered evidence for the...
Dutch scientists say they've used lab mice to determine the theory that a higher metabolism results in a shorter lifespan is unfounded. Lobke Vaanholt of the University of Groningen, who led the study, said she and her colleagues discovered mice with increased metabolism live just as long as those with slower metabolic rates. The live-fast, die-young premise, scientifically known as the rate-of-living theory, was first proposed in the 1920s, Vaanholt said. The hypothesis was that aging is...
High summer temperatures pushed higher by climate change may bring a spike in hospitalizations for respiratory problems, a European study suggests. The analysis of data from 12 European cities comes from a multicenter, three-year collaboration among epidemiologists, meteorologists and experts in public health collaboration that investigated the short-term effects of weather in Europe. The project evaluated the effects of higher temperatures on hospitalizations for a number of different...
ATLANTA, Feb. 17 /PRNewswire/ -- HotHead Technologies, Inc. today announced that the technology they have developed shows promising signs in early research results by Kennesaw State University researchers as an early warning system for heat injury. "It's exciting news that research from a university as respected as Kennesaw State has been able to verify much earlier than we anticipated, in the preliminary stages of research that the reliability and validity of this device may be so...
LONDON, Jan. 19 /PRNewswire/ -- The 2008 Frost & Sullivan Technology Innovation Award in the East European Temperature Monitoring Devices Market is presented to TECNIMED srl for pioneering THERMOFOCUS, the first non-contact clinical thermometer in the world, which is now available with a new, rapid, room temperature stabilization system. The Award is presented on an annual basis to the company that has demonstrated technological superiority within its industry and recognizes the ability...
The lack of common measurement methods among light-emitting diode (LED) and lighting manufacturers has affected the commercialization of solid-state lighting products. In a recent paper,* researchers at the National Institute of Standards and Technology (NIST) proposed a new, economical method to allow LED and lighting manufacturers to obtain accurate, reproducible, and comparable measurements of LED brightness and color.The quality of the light that high-power LEDs produce depends on their...
British scientists say they have designed a high-speed thermometer that can measure the temperature inside explosions without being damaged by the impact. The scientists at Britain's National Physical Laboratory said conventional thermometers cannot survive the shockwave, heat, snoot and debris produced by an explosion. Conventional thermocouples do not react quickly enough to capture the information. But the NPL scientists said they have designed a reusable, bomb-proof thermometer to...
Scientists at the UK's National Physical Laboratory (NPL) in Teddington have designed a high-speed thermometer that can measure the temperature inside explosions without being damaged in the impact.The shockwave, heat, soot and debris from an explosion can damage thermometers. Conventional thermocouples do not react quickly enough to capture the information. This makes modeling the interaction of an explosion with its environment problematic "“ as temperature is essential in any...
U.S. scientists say they're turning to nanoelectronics to help solve the problem of computer heat generated by ever increasing processing speeds. Researchers at the University of Virginia's School of Engineering and Applied Science hope to lay the scientific groundwork that will solve the problem with nanoelectronics. "Lap tops are very hot now, so hot they are not 'lap' tops anymore," said Assistant Professor Avik Ghosh. "The prediction is that if we continue at our current pace of...
Summer 2008 in Southern California goes down in the books as cooler than normal. The thermometer in downtown Los Angeles topped 90 degrees Fahrenheit (32.2 degrees Celsius) just once in July, August and the first two-thirds of September. But don't expect this summer's respite from the usual blistering heat to continue in the years to come, cautions a group of NASA and university scientists: The long-term forecast calls for increased numbers of scorching days and longer, more frequent heat...
