MANHATTAN, KANSAS -- Think of it as a microscopic movie: A sequence of X-ray images shows the explosion of superheated nanoparticles. The picture series reveals how the atoms in these particles move, how they form plasma and how the particles change shape.
The method of taking these pictures is a collaborative creation that involved Kansas State University researchers Artem Rudenko and Daniel Rolles, both assistant professors of physics.
A team led by researchers from the National University of Singapore (NUS) has achieved a major breakthrough in magnetic interaction. By adding a special insulator, they make electrons "twirl" their neighbouring "dance partners" to transfer magnetic information over a longer range between two thin layers of magnetic materials. This novel technique enables magnetic information to make their way from one magnetic layer to another, synonymous to the encoding and transmission of data.
The scientists from the Faculty of Physics of the Lomonosov Moscow State University conducted a study evaluating the appearance of the superconducting state in the iron-based superconductors with two energetic gaps. The report on the study was published in the latest issue of the Journal of Superconductivity and Novel Magnetism. http://dx.doi.org/10.1007/s10948-016-3386-5
Scientists at the The University of Queensland and the University of California San Francisco have found a new way to inhibit the growth of the bacterium that causes tuberculosis (TB).
UQ School of Chemistry and Molecular Biosciences Deputy Head Professor James De Voss said the discovery held promise for the development of treatments.
Plant gasses possibly dampen the temperature rise in Greenland. Plants emit compounds to deter pests or attract pollinators, and as a side effect particles are formed when the compounds interact in the air. These particles can contribute to the formation of clouds, which reflect incoming solar radiation, and thus prevent solar heat from reaching the ground and warming it additionally. Researchers from the University of Copenhagen have studied the effect of the imminent climate changes on the release of so-called "biogenic volatiles" to the atmosphere above Greenland.
An innovative joint project between the University of Stirling, Forest Research and Natural England is using woodland creation and maps from 1840 to the present day to assess the impact of past land use change on current biodiversity.
Scientists from Nanyang Technological University (NTU Singapore) at its Earth Observatory of Singapore (EOS) have discovered a way to forecast earthquakes based on slow fault movements caused by moving sub layers of the earth.
So far, scientists believe that larger earthquakes are unlikely to occur following tremors or earthquakes below a Richter scale of 2 that are caused by small vibrations or slow fault movements such as those observed in the area of Parkfield along the San Andreas Fault in California, USA.
A team of engineers has developed and tested a type of steel with a record-breaking ability to withstand an impact without deforming permanently. The new steel alloy could be used in a wide range of applications, from drill bits, to body armor for soldiers, to meteor-resistant casings for satellites.
The material is an amorphous steel alloy, a promising subclass of steel alloys made of arrangements of atoms that deviate from steel's classical crystal-like structure, where iron atoms occupy specific locations.
Two hundred and fifty-two million years ago, a series of Siberian volcanoes erupted and sent the Earth into the greatest mass extinction of all time. Billions of tons of carbon were propelled into the atmosphere, radically altering the Earth's climate. Yet, some animals thrived in the aftermath and scientists now know why. In a new study published in Scientific Reports, paleontologists from The Field Museum and their collaborators demonstrate that some ancient mammal relatives, known as therapsids, were suited to the drastic climate change by having shorter life expectancies.
The current instability and unpredictability of the world water cycle is here to stay, making society's adaptation to new risks a vital necessity when formulating development policies, a UN water expert warns.
Robert Sandford, the EPCOR Chair for Water and Climate Security at the United Nations University's Canadian-based Institute for Water, Environment and Health (UNU-INWEH), says long-term water cycle stability "won't return in the lifetime of anyone alive today."

MIAMI--A new University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study found that Miami Beach flood events have significantly increased over the last decade due to an acceleration of sea-level rise in South Florida. The researchers suggest that regional sea-level projections should be used in place of global projections to better prepare for future flood hazards in the region.
CORVALLIS, Ore. - The ocean chemistry along the West Coast of North America is changing rapidly because of global carbon dioxide emissions, and the governments of Oregon, California, Washington and British Columbia can take actions now to offset and mitigate the effects of these changes.
That is the conclusion of a 20-member panel of leading West Coast ocean scientists, who presented a comprehensive report on Monday outlining a series of recommendations to address the increase in ocean acidification and hypoxia, or extremely low oxygen levels.
New Haven, Conn. - Scientists have discovered an ancient animal that carried its young in capsules tethered to the parent's body like tiny, swirling kites. They're naming it after "The Kite Runner," the 2003 bestselling novel.
The miniscule creature, Aquilonifer spinosus, was an arthropod that lived about 430 million years ago. It grew to less than half an inch long, and there is only one known fossil of the animal, found in Herefordshire, England. Its name comes from "aquila," which means eagle or kite, and the suffix "fer," which means carry.
For the first time, Lawrence Livermore National Laboratory (LLNL) researchers have shown that carbon nanotubes as small as eight-tenths of a nanometer in diameter can transport protons faster than bulk water, by an order of magnitude.
The research validates a 200-year old mechanism of proton transport.
A nanometer is one billionth of a meter. By comparison, the diameter of a human hair is 20,000 nanometers.
