Sound Waves Direct Particles to Self-Assemble, Self-Heal
Sound Waves Direct Particles to Self-Assemble, Self-Heal
An elegantly simple experiment with floating particles self-assembling in response to sound waves has provided a new framework for studying how seemingly lifelike behaviors emerge in response to external forces. Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) demonstrated how particles, floating on top of a glycerin-water solution, synchronize in response to acoustic waves blasted from a computer speaker.

Hidden "Rock Moisture" Could Explain Forest Surviving Drough
Research led by UT has found that weathered bedrock can store a significant amount of rock moisture inside its fractures and pores. This moisture in the layer of weathered rock that is commonly located beneath soils is an important part of the water cycle on the local and global level. Tree roots tap into the rock moisture and release it back into the atmosphere as water vapor, and water flows through the fractures and becomes part of the seasonal groundwater storage (blue arrows).

DNA left by ocean animals provides rare glimpse of marine ecosystems
As ocean animals swim past, they leave behind DNA in shed cells, tissues, scales and feces. Now, scientists have shown these genetic clues can be used as forensic markers to accurately and easily survey marine life in complex deep-water environments. The ocean might as well be Mars. Like astronomers grasping at ways to identify life on a distant planet, marine scientists have no easy method for detecting sea creaturesâ?- presence in the vast watery realm.

Effects of ozone depletion felt in the Tropics
Effects of ozone depletion felt in the Tropics
Media releases, information for representatives of the media Media Relations (E) The hole in the ozone layer above Antarctica has more far-reaching consequences than previously assumed. A study by Bernese climate researchers has now shown that it even affects precipitation in the tropical regions of the Pacific, 10,000 kilometres away.

Alpine streams produce more CO2 after a warm winter
Alpine streams produce more CO2 after a warm winter
An EPFL study has for the first time measured the impact of climate change on alpine streams, and the results are quite worrying: after a low-snow winter, these streams release more carbon dioxide than they absorb. Numerous researchers are looking at the impact of climate change on the Alps. And one of the most obvious effects is the low snowfall observed in recent years.

Genetic study shakes up the elephant family tree
Genetic study shakes up the elephant family tree
CHAMPAIGN, Ill. — New research reveals that a species of giant elephant that lived 1.5 million to 100,000 years ago - ranging across Eurasia before it went extinct - is more closely related to today's African forest elephant than the forest elephant is to its nearest living relative, the African savanna elephant.

Splitting carbon dioxide using low-cost catalyst materials
EPFL scientists have built the first Earth-abundant and low-cost catalytic system for splitting CO2into CO and oxygen, an important step towards achieving the conversion of renewable energy into hydrocarbon fuels.

Eco-label in exchange for less chemicals on rice fields
Eco-label in exchange for less chemicals on rice fields
Research news Money isn't always everything: Taiwanese rice farmers are willing to produce in a more environ-mentally friendly fashion if this would earn them an eco-label for their products. For such a label, they are even prepared to accept lower compensation payments for a reduction in the use of fertilizers.

Free universal healthcare reduces health inequality in Brazil
Expanding access to primary healthcare has helped to reduce health inequalities between racial groups in Brazil. Researchers from Imperial College London and Fiocruz in Brazil have highlighted the importance of expanding universal health coverage to reduce "avoidable" deaths among Brazil's black and mixed race populations.

Rover Findings Indicate Stratified Lake on Ancient Mars
Rover Findings Indicate Stratified Lake on Ancient Mars
NASA's Curiosity rover has discovered that an ancient lake on Mars had a chemical stratification similar to that of lakes on Earth'a potential prerequisite for the presence of life. Previous exploration by the rover revealed the presence of a lake more than 3 billion years ago in Mars's Gale Crater.

Shows invasive lionfish feasting on new Caribbean fish species
The showy lionfish , a predator with venomous spines that has invaded Caribbean coral reefs, has found a new market to exploit: the " twilight zone ,” an area of ocean that lies below traditional SCUBA diving depths, where little is known about the reefs or the species that inhabit them. Researchers from the University of Washington and Smithsonian Institution have reported the first observed case of lionfish preying upon a fish species that had not yet been named.

Human activity has polluted European air for 2000 years, Black Death study finds
A new study has shown that air pollution levels across Europe have been higher than previously thought for the last 2000 years, with the exception of a four-year period during a catastrophic pandemic. The findings in this latest study will have significant implications for current public health and environmental policy which have so far deemed pre-industrial lead pollution levels to be 'natural' and so presumably 'safe'.

Sea level rise may drive coastal nesting birds to extinction
Rising sea levels and more frequent flooding events may drive coastal nesting birds around the world to extinction, a team of international researchers say following their 20-year study of Eurasian oystercatchers. Lead researcher Dr Liam Bailey from The Australian National University (ANU) said one of the main reasons for the strong decline in birds that used coastal habitats was because they had shown no response to tidal floods, which are predicted to become more frequent and severe due to climate change.

Water temperatures to drop after the Mühleberg plant closes
Water temperatures to drop after the Mühleberg plant closes
Mühleberg is the first Swiss nuclear power plant slated for decommissioning in 2019. EPFL researchers have shown that its shutdown will lower water temperatures in the Aar River and Lake Biel, and could affect waterways as far away as Germany. When the Mühleberg nuclear power station goes offline in 2019, the waters of the Aar River and Lake Biel will cool down.

Early human migration
New study reveals the importance of African groundwater in kick-starting the evolutionary history of humans An international team led by a researcher at Cardiff University believe that the movement of our ancestors across East Africa was shaped by the locations of groundwater springs. In a new study, the team argue that the springs acted as pit stops to allow early humans to survive as they moved across the African landscape.

Amazon rainforest may be more resilient to deforestation than previously thought
Amazon rainforest may be more resilient to deforestation than previously thought
Taking a fresh look at evidence from satellite data, and using the latest theories from complexity science, researchers at the University of Bristol have provided new evidence to show that the Amazon rainforest is not as fragile as previously thought. The research is published today. The Amazon forest stores about half of the global tropical forest carbon and accounts for about a quarter of carbon absorption from the atmosphere by global forests each year.
