Dynamics of polymer chains atop different materials
(Phys.org)—Technologies such as microelectronics and lithography require nanoscale polymer films that sit atop various other materials. An understanding of the interplay between the dynamics of the thin ...
Landmark discovery in gold nanorod instability
Researchers at Swinburne University of Technology have discovered an instability in gold nanoparticles that is critical for their application in future technology.
Geophysicists employ novel method to identify sources of global sea level rise
As the Earth's climate warms, a melting ice sheet produces a distinct and highly non-uniform pattern of sea-level change, with sea level falling close to the melting ice sheet and rising progressively farther away. The pattern ...
Research update: Atomic motions help determine temperatures inside Earth
(Phys.org)—In December 2011, Caltech mineral-physics expert Jennifer Jackson reported that she and a team of researchers had used diamond-anvil cells to compress tiny samples of iron—the main element of the e ...
US northeast braces for flooding after record snow
Weather forecasters and emergency officials warned Sunday that melting snow would lead to heavy flooding in parts of the US northeast, with hundreds of thousands of people told to brace for fast-rising waters.
Coastal Antarctic permafrost melting faster than expected
For the first time, scientists have documented an acceleration in the melt rate of permafrost, or ground ice, in a section of Antarctica where the ice had been considered stable. The melt rates are comparable with the Arctic, ...
Seeping Arctic methane has serious implications for Florida coastline: study
All of the methane escaping into the atmosphere causes more melting ice, oceanographer Jeff Chanton says, which causes sea levels to rise and could affect coastal real estate values -- sooner rather than later.
NASA satellites measure increase of Sun's energy absorbed in the Arctic
NASA satellite instruments have observed a marked increase in solar radiation absorbed in the Arctic since the year 2000 - a trend that aligns with the steady decrease in Arctic sea ice during the same period.
Climate change could increase levels of avian influenza in wild birds
Rising sea levels, melting glaciers, more intense rainstorms and more frequent heat waves are among the planetary woes that may come to mind when climate change is mentioned. Now, two University of Michigan researchers say ...
Shrinking glaciers won't affect South Asia water availability: study
Glacier systems that feed two key rivers in South Asia will badly retreat this century, but demands for water are still likely to be met, a study predicted on Sunday.
Antarctic seawater temperatures rising
The temperature of the seawater around Antarctica is rising according to new research from the University of East Anglia.
Earth is getting fatter
Like many of its inhabitants, the Earth is getting thicker around the middle -- that's what a new study out this week says. The increased bulge is due to the melting of the Greenland and Antarctic ice sheets.
Cold winters caused by warmer summers, research suggests
Scientists have offered up a convincing explanation for the harsh winters recently experienced in the Northern Hemisphere; increasing temperatures and melting ice in the Arctic regions creating more snowfall in the autumn ...
Glaciers sizzle as they disappear into warmer water
Scientists have recorded and identified one of the most prominent sounds of a warming planet: the sizzle of glacier ice as it melts into the sea. The noise, caused by trapped air bubbles squirting out of the disappearing ...
