Scientists have observed in unprecedented detail the birth of a massive star within a dark cloud core about 10,000 light years from Earth.
The team used the new ALMA (Atacama Large Millimetre/submillimetre Array) telescope in Chile – the most powerful radio telescope in the world – to view the stellar womb which, at 500 times the mass of the Sun and many times more luminous, is the largest ever seen in our galaxy.
Imagine turning a whiteboard, glass window or even a wooden table top into a responsive, touch sensitive surface.
A low cost system developed by Nanyang Technological University (NTU), based on the principles of vibration and imaging that is able to track the movements of multiple fingers and of objects, can do just that.
Retrofitting the system onto existing flat-panel TVs will transform it into new, touch sensitive display screens, at only a fraction of the cost of new touch-sensitive display screens, which can cost tens of thousands of dollars.
The seeding of marine clouds to cool sea surface temperatures could protect threatened coral reefs from being bleached by warming oceans. Research, published in Atmospheric Science Letters, proposes that a targeted version of the geo-engineering technique could give coral a fifty year 'breathing space' to recover from acidification and warming.
Oxford -- A team of researchers from the University of Rostock in Germany has developed a new way to rapidly produce high strength metallic alloys, at a lower cost using less energy than before. It's expected that this breakthrough will profoundly change how we produce components used in a diverse range of applications; including transport and medical devices.
The most massive and brightest stars in the galaxy form within cool and dark clouds but the process remains not just shrouded in dust, but also in mystery [1]. An international team of astronomers has now used ALMA to perform a microwave prenatal scan to get a clearer look at the formation of one such monster star that is located around 11 000 light-years away, in a cloud known as the Spitzer Dark Cloud (SDC) 335.579-0.292.
"Because rare but potentially serious adverse events of prescription drugs are often discovered only after market approval, observational postmarketing studies constitute an important part of the U.S. drug safety system," write Kevin Fain, J.D., M.P.H., of the Johns Hopkins Bloomberg School of Public Health, Baltimore, and colleagues. "In 2007, Congress passed the Food and Drug Administration Amendments Act (FDAAA), which authorized the FDA to require postmarketing studies for a prescription drug's approval and mandate adherence to study deadlines.
As of 8 a.m. EDT on July 9, a tropical storm warning was in effect for: Barbados, Dominica, St Lucia, Martinique, Guadeloupe, Puerto Rico and southern coast of the Dominican Republic from Cabo Engano to the border with Haiti. In addition, a tropical storm watch was in effect for the U.S. Virgin Islands, Saint Vincent, Vieques and Culebra, Haiti, the northern coast of the Dominican Republic, Turks and Caicos and the southeastern Bahamas.
Visible and infrared satellite data show strong thunderstorms surrounding the low-level center of the tropical storm turned Typhoon Soulik. NASA's Aqua satellite passed over Typhoon Soulik in the Northwestern Pacific Ocean on July 9 and two instruments showed the power in the typhoon's center.
Infrared imagery from the AIRS instrument aboard NASA's Aqua satellite revealed that Erick, now a tropical depression has reduced in strength and size and continues to weaken.
Before the Big Bang, space-time as we know it did not exist. So how was it born? The process of creating normal space-time from an earlier state dominated by quantum gravity has been studied for years by theorists at the Faculty of Physics, University of Warsaw. Recent analyses suggest a surprising conclusion: not all elementary particles are subject to the same space-time.
The third tropical cyclone of the Atlantic Ocean season developed in the Atlantic and not in the Gulf of Mexico as the previous two systems,Tropical Storm Chantal.The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA's Aqua satellite captured a visible image of Tropical Storm Chantal on July 7 at 12:15 p.m. EDT when it was located off the coast of Brazil. The highest and strongest thunderstorms (that cast shadows on the surrounding lower storms) were around the center of circulation.
When NASA's Aqua satellite passed over Tropical Storm Soulik in the Northwestern Pacific Ocean, the MODIS and AIRS instruments captured images that showed the storm's eastern quadrant covered the Marianas Islands and that the storm has become more organized in the last day.
Tropical Storm Erick has been bringing some rain and rough surf along the southwestern coast of Mexico for a couple of days, and on July 7, 2013, NASA's TRMM satellite saw two areas of heavy rain within Erick on opposite ends of the storm. Meanwhile, the rainfall from the remnants of nearby Tropical Depression Dalila had dissipated.
A new low-cost method of in-vitro fertilization developed at the University of Colorado Boulder that performed successfully in recent human clinical trials in Belgium may help thousands of infertile couples in developing countries.
DARIEN, IL – A new study suggests that CPAP therapy reduces nightmares in veterans with post-traumatic stress disorder (PTSD) and obstructive sleep apnea (OSA).
Results show that the mean number of nightmares per week fell significantly with CPAP use, and reduced nightmare frequency after starting CPAP was best predicted by CPAP compliance.
