Antarctic Snowscapes for Predicting the Weather
Antarctic Snowscapes for Predicting the Weather
EPFL scientists measured for the first time - at centimeter resolutions - how the snowscape of Antarctic ice in the sea changed, before and after a blizzard. This data will help build better weather models for the South Pole and the world's climate. EPFL scientists provided the first detailed measurements of how a blizzard affects snow cover on an Antarctic ice floe.

Herbivorous mammals have bigger bellies
Herbivorous mammals have bigger bellies
The researchers have studied the shape of the ribcage in more than 120 tetrapods - from prehistoric times up to the present day. (Image: UZH) What do enormous dinosaurs have in common with tiny shrews' They are both four-legged vertebrates, otherwise known as tetrapods. In the course of evolution, tetrapods developed various body shapes and sizes - from the mouse to the dinosaur - to adapt to different environments.

Origin of the turtle shell lies in digging
Origin of the turtle shell lies in digging
In today's turtles the shell has a key protective function. The animals can withdraw into it and protect themselves against predators.

A new tool to ensure the safety of injecting CO2 underground
A new tool to ensure the safety of injecting CO2 underground
01.07.16 - Sequestering carbon dioxide underground is likely to play a key role in meeting reduction targets set at the IPCC conference in Paris last year.

Global ethane concentrations rising
Global ethane concentrations rising
Measurements at 49 sites all over the world show that, since 2010, long-declining global atmospheric ethane concentrations are on the uptick again in the Northern Hemisphere. The new study by an international team of researchers concluded that the rise was most likely largely due to greater oil and gas production in the US.

Using turbulence to keep dams clean
Using turbulence to keep dams clean
20.04.16 - Sediment builds up in reservoir water and can prevent dams from operating properly. EPFL researchers have come up with a method of keeping sediment in suspension and allowing it be flushed out. All dams on earth, from the Mauvoisin Dam in Valais Canton to the Xiaowan Dam in China, have the same problem: sediment accumulating in the reservoir.

Bubbles lead to disaster
Bubbles lead to disaster
Why are volcanologists interested in vapour bubbles? Because they can accumulate in a magma reservoir underneath a volcano, priming it to explode.

Traces of life discovered in mantle rock
Traces of life discovered in mantle rock
An international expedition, led by ETH Professor Gretchen Bernasconi-Green, has discovered traces of life in a core sample. The geologist explains what this means. An international team of scientists returned last December from an IODP (International Ocean Discovery Program) expedition to the Atlantis Massif in the Atlantic Ocean.

Migration routes of mantle plumes discovererd
Migration routes of mantle plumes discovererd
Mars's southern hemisphere has a tumultuous past that was marked by significant volcanism. Now an ETH researcher has discovered that these many volcanoes are not distributed randomly but in fact lie along specific lines. These could well correspond to different paths taken by mantle plumes. Planetary scientist Giovanni Leone at ETH Zurich's Institute of Geophysics has lost count of the hours he has spent poring over high-resolution satellite images to study structures on the surface of Mars.

Topography shapes biodiversity, and not only through temperature
Topography shapes biodiversity, and not only through temperature
A warming climate is likely to drive species to higher, cooler altitudes. A new study highlights a less obvious, yet crucial way in which their new habitat could differ from the one they leave behind. Mountains are home to many living species, with biodiversity typically peaking at mid-altitudes. Scientists have long struggled to explain why this is the case, invoking factors such as low temperatures at high elevations or human disturbance further down.

How two degrees may turn into four
How two degrees may turn into four
The world has decided to adopt measures to prevent average global warming from exceeding the two-degree mark. But what does this mean for temperature and the distribution of heavy precipitation on a regional level? Climate researchers have now calculated this. At the recent COP21 climate conference in Paris, delegates reached an agreement that plans to limit global warming to "well below" two degrees Celsius.

Meltwater from the Greenland ice sheet releasing faster
Meltwater from the Greenland ice sheet releasing faster
The firn layers of the Greenland ice sheet might store less meltwater than previously assumed. Researchers from the USA, Denmark and the University of Zurich fear that this could lead to increased release of the meltwater into the oceans. The near-surface layers of the Greenland ice sheet are made up of snow that is gradually being converted into glacier ice.
