The Galápagos Islands are home to some of the most active volcanoes in the world, with more than 50 eruptions in the last 200 years. Yet until recently, scientists knew far more about the history of finches, tortoises, and iguanas than of the volcanoes on which these unusual fauna had evolved.

An innovative program from UNC's Frank Porter Graham Child Development Institute (FPG) and 6 partner universities is preparing students with autism for life after high school.
"Public high schools may be one of the last best hopes for adolescents with autism—and for their families," said FPG director Samuel L. Odom. "Many of these students will face unemployment and few social ties after school ends."
Inspired by this embryonic induction mechanism, Ingber and Basma Hashmi, a Ph.D. candidate at SEAS who is the lead author of the current paper, set out to develop a way to engineer artificial teeth by creating a tissue-friendly material that accomplishes the same goal. Specifically, they wanted a porous sponge-like gel that could be impregnated with mesenchymal cells, then, when implanted into the body, induced to shrink in 3D to physically compact the cells inside it.
WASHINGTON, March 5, 2014–Disasters both natural and human-caused can damage or destroy data and communications networks. Several presentations at the 2014 OFC Conference and Exposition, being held March 9-13 in San Francisco, Calif., USA will present new information on strategies that can mitigate the impacts of these disasters.
New Algorithm Finds Safe Refuge for Cloud Data
Fairfax, Va., March 5, 2014— The American Society for Radiation Oncology (ASTRO) has issued a new white paper, "A review of safety, quality management, and practice guidelines for high-dose-rate brachytherapy," that recommends specific guidance to follow in the delivery of high-dose-rate (HDR) brachytherapy to improve quality and patient safety, according to the manuscript published in the March-April 2014 print issue of Practical Radiation Oncology (PRO), the official clinical practice journal of ASTRO.
Therefore, such a concert hall shape affects perceived dynamic range even though rooms itself amplify all passages the same amount.
"Dynamic expression is an inseparable part of music. For this reason, a concert hall's ability to transmit the orchestra's played dynamics is one of the most important criteria of good acoustics. Our research is the first that explains how halls influence perception of dynamic expression," Dr. Jukka Pätynen says.
WASHINGTON D.C. Mar. 4, 2014 -- Animal flight behavior is an exciting frontier for engineers to both apply knowledge of aerodynamics and to learn from nature's solutions to operating in the air. Flying snakes are particularly intriguing to researchers because they lack wings or any other features that remotely resemble flight apparatus.
Before you envision flying snakes raining down from the sky, the ones involved in this study are small -- about 1 meter in length and the width of your thumb -- and live in the lowland tropical forests of Asia and Southeast Asia.
From the Statue of Liberty in New York to the Tower of London or the Sydney Opera House -- sea-level rise not only affects settlement areas for large parts of the world population but also numerous sites of the UNESCO World Heritage. This is shown in a new study by Ben Marzeion from the University of Innsbruck and Anders Levermann from the Potsdam Institute for Climate Impact Research.
Some of the world's most recognisable and important landmarks could be lost to rising sea-levels if current global warming trends are maintained over the next two millennia.
This is according to a new study, published today, 5 March, in IOP Publishing's journal Environmental Research Letters, that has calculated the temperature increases at which the 720 sites currently on the list of UNESCO World Heritage sites would be impacted by subsequent sea-level rises.
They slither, they hiss, they... fly.
Don't let their wingless bodies fool you--some snakes can glide as far as 100 feet through the air, jumping off tree branches and rotating their ribs to flatten their bodies and move from side to side. New research from a George Washington University professor investigates the workings behind the flight and whether they can be applied to mechanical issues.
The ice-free season across the Arctic is getting longer by five days per decade, according to new research from a team including Prof Julienne Stroeve (UCL Earth Sciences). New analysis of satellite data shows the Arctic Ocean absorbing ever more of the sun's energy in summer, leading to an ever later appearance of sea ice in the autumn. In some regions, autumn freeze-up is occurring up to 11 days per decade later than it used to.
A new twist on a very old physics technique could have a profound impact on one of the most buzzed-about aspects of nanoscience.
Researchers at the University of Cincinnati have found that their unique method of light-matter interaction analysis appears to be a good way of helping make better semiconductor nanowires.
As NOAA's GOES-East satellite sat in a fixed orbit in space it monitored and provided visible and infrared imagery of the major winter storm that hit the U.S. east coast on March 2 and 3. Now, that data has been compiled and made into a video at NASA.
The Earth's outer layer is made up of a series of moving, interacting plates whose motion at the surface generates earthquakes, creates volcanoes and builds mountains. Geoscientists have long sought to understand the plates' fundamental properties and the mechanisms that cause them to move and drift, and the questions have become the subjects of lively debate.
A study published online Feb. 27 by the journal Science is a significant step toward answering those questions.
ST. PAUL, Minn., March 4, 2014 – Higher temperatures, more heavy precipitation, and drought. It's all expected in the Central Hardwoods Region of southern Indiana, southern Illinois, and the Missouri Ozarks, according to a new report by the U.S. Forest Service, and partners that assesses the vulnerability of the region's forest ecosystems and its ability to adapt to a changing climate.
