Two neonicotinoid insecticides may have inadvertent contraceptive effects on male honey bees
Two neonicotinoid insecticides may have inadvertent contraceptive effects on male honey bees
Male honey bees, called drones, can be affected by two neonicotinoid insecticides by reducing male honey bee lifespan and number of living sperm. Both insecticides are currently partially banned in Europe. Researchers from Bern, Switzerland, together with partners from Thailand and Germany, call for more thorough environmental risk assessments of these neonicotinoids.

Jasmonate-deficient tobacco plants attract herbivorous mammals
Jasmonate-deficient tobacco plants attract herbivorous mammals
Media releases, information for representatives of the media Media Relations (E) Tobacco plants which lack the hormones responsible for nicotine production are feasted on by rabbits and other mammals. Coyote tobacco (Nicotiana attenuata) produces a potent neurotoxic substance: nicotine. The production of nicotine is regulated by plant hormones called jasmonates.

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.

The causes of soil consumption
The causes of soil consumption
The soil is still under threat from urban sprawl. Small municipalities with little planning capacity and more easily accessible conurbations in particular are doing little to counter the issue. Researchers from the National Research Programme "Sustainable Use of Soil as a Resource" (NRP 68) have analysed the reasons for this by surveying Swiss municipalities.

Nature knows how to do it - as does
As part of the "LightChEC" research project at the University of Zurich, Empa scientists are working with other researchers on a novel method of artificial photosynthesis - photocatalysis, which uses a purely chemical process to split water into hydrogen and oxygen. Unlike other methods, it does not involve the electrolysis of water.

The shape of cities shapes the weather
The shape of cities shapes the weather
17.05.16 - The features that make cities unique are important to understanding how cities affect weather and disperse air pollutants, researchers highlight in a new study. Compared to their surroundings, cities can be hot - hot enough to influence the weather. Industrial, domestic, and transportation-related activities constantly release heat, and after a warm day, concrete surfaces radiate stored heat long into the night.

How effective is fish stocking in Swiss lakes?
How effective is fish stocking in Swiss lakes?
In the last century, the natural reproduction of whitefish and Arctic char in several Swiss lakes was adversely affected by high levels of nutrient inputs. So far, stocking measures have been implemented in efforts to support fish populations and maintain yields. The effectiveness of these measures varies according to the particular species and lake.

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.

City Moths Avoid the Light
City Moths Avoid the Light
Moths and other nocturnal insects are attracted by artificial light sources. Swiss zoologist study how this behavior differst in animals from areas with high and low light pollution (Image: A. Bieger). The globally increasing light pollution has negative effects on organisms and entire ecosystems.

Monitoring greenhouse gas emissions independently
Monitoring greenhouse gas emissions independently
Mistakes can happen when estimating emissions of greenhouse gases such as carbon dioxide and methane. Researchers funded by the Swiss National Science Foundation have developed a method to independently validate national statistics. The signatory countries of the Kyoto Protocol and the new Paris Agreement have committed to reduce global warming.

Human eyes assist drones, teach machines to see
21.03.16 - Drone images accumulate much faster than they can be analyzed. Researchers have developed a new approach that combines crowdsourcing and machine learning to speed up the process. Who would win in a real-life game of "Where's Waldo," humans or computers? A recent study suggests that when speed and accuracy are critical, an approach combing both human and machine intelligence would take the prize.

Everyone sees the world through their own prism
How can public opinion be influenced in favour of climate protection? ETH political scientist Thomas Bernauer explored the question in a recent study. His sobering answer is that there is no magic formula. Policy-makers have been charged with taking appropriate measures against the looming threat of climate change.

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.
