Working at temperatures matching the interior of the sun, researchers have been able to determine, for the first time in history, iron’s role in inhibiting energy transmission from the Sun's center to near the edge of its radiative band. Because that role is much greater than formerly surmised, the experimentally derived amount of iron’s opacity helps close a theoretical gap in the Standard Solar Model, used to model the behavior of stars.
NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory’s drill. Researchers used Curiosity’s onboard Sample Analysis at Mars laboratory a dozen times in a 20-month period to sniff methane in the atmosphere. During two of those months, four measurements averaged seven ppb.
Using a computer algorithm that can sift through mounds of genetic data, researchers from Brown University have identified several networks of genes that, when hit by a mutation, could play a role in the development of multiple types of cancer. The algorithm, called Hotnet2, was used to analyze genetic data from 12 different types of cancer assembled as part of the pan-cancer project of The Cancer Genome Atlas (TCGA).
Although there are a diverse range of applications for predictive analytics in R&D, two common basic requirements are data and insight. Data may be generated by running experiments/analyses, or re-applied from previous work when available. Insights come from application of knowledge — both explicitand tacit. There are a variety of roles for informatics in predictive analytics...
The mystery of where Earth's water came from got murkier on December 10, 2014, when some astronomers essentially eliminated one of the chief suspects: comets. Over the past few months, the European Space Agency's Rosetta space probe closely examined the type of comet that some scientists theorized could have brought water to our planet 4 billion years ago. It found water, but the wrong kind.
At a White House ceremony on November 20, 2014, President Obama presented the National Medal of Science and National Medal of Technology and Innovation to individuals who have made outstanding contributions to science and engineering. The awards are the nation's highest honors for achievement and leadership in advancing the fields of science and technology.

The Council on Competitiveness has released a new report that explores the value of government leadership in supercomputing for industrial competitiveness, titled Solve. The Exascale Effect: the Benefits of Supercomputing Investment for U.S. Industry. As the federal government pursues exascale computing to achieve national security and science missions, Solve examines how U.S.-based companies also benefit from leading-edge computation
New maps of Saturn’s moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one.
Scientists have used computer simulations to show how bacteria are able to destroy antibiotics — a breakthrough that will help develop drugs which can effectively tackle infections in the future. Researchers at the University of Bristol focused on the role of enzymes in the bacteria, which split the structure of the antibiotic and stop it from working, making the bacteria resistant.

The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Chemistry to Eric Betzig of Janelia Farm Research Campus, Howard Hughes Medical Institute, Stefan W. Hell of the Max Planck Institute for Biophysical Chemistry, Göttingen and German Cancer Research Center, and William E. Moerner of Stanford University “for the development of super-resolved fluorescence microscopy.”
Water was crucial to the rise of life on Earth and is also important to evaluating the possibility of life on other planets. Identifying the original source of Earth’s water is key to understanding how life-fostering environments come into being and how likely they are to be found elsewhere. New work has found that much of our Solar System’s water likely originated as ices that formed in interstellar space.
For the first time, scientists have discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers. The core of the nanothreads is a long, thin strand of carbon atoms arranged just like the fundamental unit of a diamond's structure.
India celebrated putting a spacecraft into orbit around Mars on September 24, 2014, hoping the rare feat will show the world it is open for business in space exploration and inspire a new generation of homegrown scientists to help drive growth. Those motivations help explain why India, a poor country of 1.2 billion, even invests in a space program when so many of its people lack access to proper toilets, electricity and health care.

It all begins in the brain as a flood, tens of millions of neurotransmitters handed off from one neuron to another in just a fraction of a second. Memories, dreams and learning share a common thread in this exchange of electrical and chemical signals by the nearly 100 billion spindly neurons of the brain, each cell networked to 10,000 others.
An international collaboration has achieved the synthesis of a new class of chemical compounds for superheavy elements. For the first time, a chemical bond was established between a superheavy element — seaborgium (element 106) in the present study — and a carbon atom.
Scientists have generated a new star-shaped molecule made up of interlocking rings, which is the most complex of its kind ever created. Known as a ‘Star of David’ molecule, scientists have been trying to create one for over a quarter of a century. Consisting of two molecular triangles, entwined about each other three times into a hexagram, the structure’s interlocked molecules are tiny.
StarDrop 5.5 is a suite of software for guiding decisions in drug discovery, helping project teams quickly identify high-quality compounds. It works by evaluating complex data, which is often uncertain because of experimental variability or predictive error.
The quest to create artificial “squid skin” — camouflaging metamaterials that can “see” colors and automatically blend into the background — is one step closer to reality, thanks to a color-display technology unveiled by Rice University’s Laboratory for Nanophotonics. The new full-color display technology uses aluminum nanoparticles to create the vivid red, blue and green hues found in today’s top-of-the-line LCD televisions and monitors.

Earth's protective but fragile ozone layer is beginning to recover, largely because of the phase-out since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. scientific panel reported September 10, 2014, in a rare piece of good news about the health of the planet. Scientists said the development demonstrates that, when the world comes together, it can counteract a brewing ecological crisis.
Chemical reactions drive the mechanisms of life as well as a million other natural processes on earth. These reactions occur at a wide spectrum of temperatures, from those prevailing at the chilly polar icecaps to those at work churning near the earth’s core. At nanokelvin temperatures, by contrast, nothing was supposed to happen. Chemistry was expected to freeze up. Experiments and theoretical work have now show that this is not true.
