Malignant melanoma is as much as 35% more common among people who live in Gothenburg and the region's coastal municipalities than those who live inland. Researchers at Sahlgrenska Academy, University of Gothenburg, Sweden, have found that the number of malignant melanoma cases in the Västra Götaland region has quadrupled since 1970.

Malignant melanoma has become increasingly common in the Western world over the past few decades. One of the biggest factors has been excessive and unprotected sunbathing despite widespread awareness of the health risks.

Blasting over two million lights years from the centre of a distant galaxy is a supersonic jet of material that looks strikingly similar to the afterburner flow of a fighter jet, except in this case the jet engine is a supermassive black hole and the jet material is moving at nearly the speed of light.

Research published over the weekend in the Astrophysical Journal Letters shows the galaxy-scale jet to have bright and dark regions, similar to the phenomenon in an afterburner exhaust called 'shock diamonds.'

New research indicates an increase in the number of US deaths and hospitalizations related to pulmonary hypertension. A research team from Howard University Hospital, Washington, DC, examined multiple cause of death mortality data from the National Vital Statistics System and hospital discharge data from the National Hospital Discharge Survey for 1999-2009. Results showed that since 1999, the number of deaths and hospitalizations, as well as death rates and hospitalization rates, have increased for pulmonary hypertension, particularly among women and older adults.

Washington, D.C.— Solar radiation management is a type of geoengineering that would manipulate the climate in order to reduce the impact of global warming caused by greenhouse gasses. Ideas include increasing the amount of aerosols in the stratosphere, which could scatter incoming solar light away from Earth's surface, or creating low-altitude marine clouds to reflect these same rays.

Cambridge, Mass., and Washington, D.C. - October 21, 2012 - By tailoring geoengineering efforts by region and by need, a new model promises to maximize the effectiveness of solar radiation management while mitigating its potential side effects and risks. Developed by a team of leading researchers, the study was published in the November issue of Nature Climate Change.

Enhanced local electric fields are predominant in nonlinear optical properties, particularly in surface-enhanced Raman scattering (SERS), which is a sensitive technique used for the detection of trace amounts of chemicals. Analysis of the electric fields around nanostructures indicates that they can provide a basic foundation to obtain greater SERS intensity. Professor ZHANG Zhongyue and his group from the College of Physics and Information Technology at Shaanxi Normal University have proposed a novel scheme to enhance the local electric fields around nanostructures.

Prapiroon is both extra-large and now extra-tropical in the western North Pacific Ocean. NASA's Terra satellite captured an image of the large storm after Prapiroon became extra-tropical.

A comprehensive study of hundreds of galaxies observed by the Keck telescopes in Hawaii and NASA's Hubble Space Telescope has revealed an unexpected pattern of change that extends back 8 billion years, or more than half the age of the universe.

Spectroscopic observations of distant galaxies taken with the 10-meter telescopes at the W. M. Keck Observatory on Hawaii, when combined with images taken by the Hubble Space Telescope plus supercomputer simulations to help interpret the observations, together reveal a major surprise: that a standard assumption about the evolution of galaxies is not correct.

Teenagers and university students are unaware of the negative consequences of alcohol consumption or the chances of developing an addiction as a result. In addition, they start at a younger and younger age and drink more and stronger alcohol according to a study headed by the University of Valencia.

Tropical Storm Maria is moving away from Japan and strong wind shear is pushing its rainfall east of the storm's center, according to NASA satellite imagery.

When the lamp is shattered,The light in the dust lies dead.When the cloud is scattered,The rainbow's glory is shed.

Heavy rainfall returned to Typhoon Prapiroon for a brief time on Oct. 18 when NASA's TRMM satellite passed overhead. Prapiroon is battling strong wind shear and is expected to transition into an extra-tropical storm in the next day.

Hurricane Rafael is no longer a tropical cyclone. The storm merged with a cold front on Oct. 18, but not before NASA's Terra satellite captured an image of the storm when it was in its last day as a hurricane.

The Moderate Resolution Imaging Spectrometer (MODIS) instrument aboard NASA's Terra captured a visible image of Hurricane Rafael in the North Atlantic on Oct. 17 at 1440 UTC (10:40 a.m. EDT). Although Rafael was far from land, its northwestern fringe clouds were brushing Nova Scotia, Canada.

Noise can be distracting, especially to a person trying to concentrate on a difficult task. Studying annoying noises helps architects design better building environments and policy makers choose effective noise regulations. To better understand how short noise bursts affect humans' mental state, researchers from the University of Nebraska – Lincoln played quarter-second-long white noise clips to test subjects as they worked on arithmetic problems.
