The cost of emergency care: Emergency care cost estimates are too low

U.S. emergency care costs may be more than twice previously published estimates, according to a new analysis that critiques those estimates, argues for improved accounting, and suggests considering the value of emergency care as well as total spending.

PROVIDENCE, R.I. [Brown University] — Alternately praised in the aftermath of horrible tragedies as a heroic service and lamented in policy debates as an expensive safety net for people without primary care, emergency medicine is often a hot topic. Despite that importance, an analysis published online April 26 in the Annals of Emergency Medicine finds that national expenditures on emergency care are likely significantly higher than previously thought.

“The ER has become increasingly important as a place where people go for acute unscheduled care, however there has been little rigorous analysis of its cost structure,” said paper lead author Dr. Michael Lee, assistant professor of emergency medicine in the Warren Alpert Medical School of Brown University and a physician at Rhode Island Hospital and The Miriam Hospital.

Pebbly Rocks Testify to Old Streambed on Mars

PASADENA, Calif. – Detailed analysis and review have borne out researchers’ initial interpretation of pebble-containing slabs that NASA’s Mars rover Curiosity investigated last year: They are part of an ancient streambed.

The rocks are the first ever found on Mars that contain streambed gravels. The sizes and shapes of the gravels embedded in these conglomerate rocks — from the size of sand particles to the size of golf balls — enabled researchers to calculate the depth and speed of the water that once flowed at this location.

Keeping beverages cool in summer: It’s not just the heat, it’s the humidity

In spring a person’s thoughts turn to important matters, like how best to keep your drink cold on a hot day. Though this quest is probably as old as civilization, University of Washington climate scientists have provided new insight. (more…)

How the turtle got its shell

The turtle has been in no rush to give up the secret of its shell — but after two centuries of close study, scientists are filling in the story of a structure unique in the history of life.

New research led by Tyler Lyson of Yale University and the Smithsonian Institution pushes back the origins of the turtle shell by about 40 million years, linking it to Eunotosaurus, a 260-million-year-old fossil reptile from South Africa. The work strengthens the fossil record and bolsters an existing theory about shell development while providing new details about its precise evolutionary pathway. (more…)

Forecast for Titan: Wild Weather Could be Ahead

Saturn’s moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct. Scientists think that as the seasons change in Titan’s northern hemisphere, waves could ripple across the moon’s hydrocarbon seas, and hurricanes could begin to swirl over these areas, too. The model predicting waves tries to explain data from the moon obtained so far by NASA’s Cassini spacecraft. Both models help mission team members plan when and where to look for unusual atmospheric disturbances as Titan summer approaches.

“If you think being a weather forecaster on Earth is difficult, it can be even more challenging at Titan,” said Scott Edgington, Cassini’s deputy project scientist at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “We know there are weather processes similar to Earth’s at work on this strange world, but differences arise due to the presence of unfamiliar liquids like methane. We can’t wait for Cassini to tell us whether our forecasts are right as it continues its tour through Titan spring into the start of northern summer.” (more…)

Moth-Inspired Nanostructures Take the Color Out of Thin Films

Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the “thin-film interference” phenomenon commonly observed in nature. This can potentially improve the efficiency of thin-film solar cells and other optoelectronic devices. (more…)

In the mountains of the Sichuan Province of southwestern China, the Wolong Panda Nature Reserve is home to both the endangered peaceful mountain dwellers it is mandated to protect and the residents of the valley where the habitat of the giant panda is being restored. It’s also home base for research that holds important insights into the future of pandas and people. (more…)

Study finds more than 52 percent of organizations turning to the cloud for business growth

Microsoft-commissioned study highlights opportunity for hosting providers as companies look to achieve growth with hybrid cloud solutions.

REDMOND, Wash. — May 29, 2013 — Companies and organizations are increasingly turning to the cloud as a strategy for business growth, according to The New Era of Hosted Services, a Microsoft-commissioned study conducted by 451 Research LLC. As they look ahead to the next two years, more than 52 percent of organizations identify the cloud as beneficial for either growing their business or realigning their organization to a new company strategy. Along with this drive for growth comes significant opportunity for Microsoft hosting partners as customers look to grow their business with a hybrid cloud consumption model.

“The next two years will be the era of hybrid cloud, with 68 percent of customers planning to adopt hybrid cloud models — up from 49 percent today,” said Marco Limena, vice president, Hosting Service Providers Business, Microsoft. “In addition, the survey found that as customers begin to move their IT environments into the cloud, software is sticky and brand is even more important.” (more…)
