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.

A tool for monitoring the biodiversity of Swiss livestock
A tool for monitoring the biodiversity of Swiss livestock
EPFL researchers have created an online platform for monitoring the genetic diversity of livestock and the sustainability of animal farming in Switzerland. This project, which was developed in partnership with the Federal Office for Agriculture, could serve as a model for other countries. "With the GenMon platform, our aim was to develop a practical tool for automating the process of monitoring livestock in Switzerland," explains Solange Duruz, a PhD student in the Laboratory of Geographic Information Systems (LASIG) and lead author of the article, which appeared in the journal PLOS One .

Coral reefs in the Gulf of Aqaba may survive global warming
Coral reefs in the Gulf of Aqaba may survive global warming
Coral reefs in the Red Sea's Gulf of Aqaba can resist rising water temperatures. If they survive local pollution, these corals may one day be used to re-seed parts of the world where reefs are dying.

Understanding changes in extreme precipitation
Understanding changes in extreme precipitation
An ETH study explores why the increase in extreme precipitation is not the same across every region. This paves the way toward improved regional climate projections. Most climate scientists agree that heavy rainfall will become even more extreme and frequent in a warmer climate. This is because warm air can hold more moisture than cold air, resulting in heavier rainfall.

Extinction of Alpine Plants May Remain Undetectable for a Long Time
Extinction of Alpine Plants May Remain Undetectable for a Long Time
For alpine plant species, climate change presents a special challenge: To escape increased greenhouse warming, the species have to move to a higher-altitude habitat.

Light can improve perovskite solar cell performance
Light can improve perovskite solar cell performance
Publishing in Nature, EPFL scientists show how light affects perovskite film formation in solar cells, which is a critical factor in using them for cost-effective and energy-efficient photovoltaics.  Perovskites are materials of immense interest in solar energy technology lately, as they promise to bring down the cost of solar cells to very low levels.

A simplified fabrication process for high efficiency solar cells
A simplified fabrication process for high efficiency solar cells
A team of EPFL and CSEM researchers in Neuchâtel has featured in Nature Energy with an astonishing new method for the creation of crystalline solar cells. These cells have electrical contacts at the back, which removes all shadowing at the front. Thanks to this new inexpensive approach, the fabrication process is greatly simplified, with efficiencies in the laboratory already surpassing 23%.

Little Ice Age displaced the tropical rain belt
Little Ice Age displaced the tropical rain belt
Even small changes in global temperature can trigger a migration of the tropical rain belt. This can also lead to climate change, as described by a team of researchers from ETH Zurich and other universities. The tropical rain belt, also known as the Intertropical Convergence Zone (ITCZ), is in a state of constant migration.

Unraveling the mystery of snowflakes, from the Alps to Antarctica
Unraveling the mystery of snowflakes, from the Alps to Antarctica
Using a special multi-angle camera, EPFL researchers have gained important insights into the structure of snowflakes. Their aim is to improve the accuracy of snowfall measurements and winter weather forecasts. Imagine taking pictures of thousands of snowflakes from three different angles with a specialized instrument installed at an altitude of 2,500 meters.

Control pest fungi in an environmentally
The St. Gallen-based Empa biotech spin-off, MycoSolutions AG, has developed a new fungal product that improves the soil and controls pest fungi in an environmentally friendly way. Wooden poles remain in use much longer, leading to cost savings of millions for operators. A "Proof-of-Concept" is now available for the integrated wood preservation method.

Sun's impact on climate change quantified for first time
Sun’s impact on climate change quantified for first time
For the first time, model calculations show a plausible way that fluctuations in solar activity could have a tangible impact on the climate. Studies funded by the Swiss National Science Foundation expect human-induced global warming to tail off slightly over the next few decades. A weaker sun could reduce temperatures by half a degree.

Measuring the impact of a city's buildings on the weather
Measuring the impact of a city's buildings on the weather
A new model developed at EPFL can help engineers and meteorologists quickly calculate the effect that city buildings have on local weather patterns. A blinds manufacturer is already interested in it, and climate scientists could be next. The shape of city buildings, how they are arranged, and the heat they generate all affect the local weather.

Less snow and a shorter ski season in the Alps
Less snow and a shorter ski season in the Alps
After long-awaited snowfall in January, parts of the Alps are now covered with fresh powder and happy skiers. But the Swiss side of the iconic mountain range had the driest December since record-keeping began over 150 years ago, and 2016 was the third year in a row with scarce snow over the Christmas period.

Laissez-faire is not good enough for reforestation
Laissez-faire is not good enough for reforestation
If degraded and logged areas of tropical forests are left to nature, the populations of certain endangered tree species are not able to recover. This applies in particular to trees with large fruit where the seeds are distributed by birds, as ETH scientists have shown in a rainforest in India. In order to restore tropical rainforests, it is not enough to simply set up protected areas and leave them to their own devices.
