Invasiveness facilitated by a large gene pool
Invasiveness facilitated by a large gene pool
In Lake Constance, sticklebacks are occupying increasingly varied habitat types - in recent years even including the open and deep waters of the lake. In an Eawag review undertaken as part of the "SeeWandel" project, these uniquely diverse ecological adaptations are explained in terms of renewed contact between three stickleback lineages - including one originating from the Baltic region, whose genetic material is as yet rarely observed in other Swiss lakes.

Lack of diversity in science
Lack of diversity in science
Women and the Global South are strikingly underrepresented Most publications in leading scientific journals are by male authors from English-speaking countries. This changes only slowly, according to a recent study on diversity in top authorship, concludes Bea Maas from the University of Vienna. Her new study examines the (non-existent) diversity in top authorship in science.

Ecology: The Scientific Literature Dominated by Men and a Handful of Countries
Publishing in peer-reviewed scientific journals is crucial for the development of a researcher's career. The scientists that publish the most often in the most prestigious journals generally acquire greater renown, as well as higher responsibilities. However, a team involving two CNRS researchers 1 has just shown that the vast majority of scientific articles in the fields of ecology and conservation biology are authored by men working in a few Western countries.

Follow the emotions to fight climate change
Follow the emotions to fight climate change
A researcher from the University of Geneva has compiled the scientific literature of the last five years linking emotion and climate change, highlighting the main levers that will make it possible to strengthen behaviour in favour of sustainable development. Emotions are often the victim of their bad reputation, as they are considered "irrational", but they play a major role in helping us assess the world and guide our behaviour.

Understanding the Spatial and Temporal Dimensions of Landscape Dynamics
Heidelberg geoinformation scientists develop new computer-based method to analyse topographic changes The Earth's surface is subject to continual changes that dynamically shape natural landscapes. Global phenomena like climate change play a role, as do short-term, local events of natural or human origin.

Extinct atom reveals the long-kept secrets of the solar system
Extinct atom reveals the long-kept secrets of the solar system
Using the extinct niobium-92 atom, ETH researchers have been able to date events in the early solar system with greater precision than before. The study concludes that supernova explosions must have taken place in the birth environment of our sun. If an atom of a chemical element has a surplus of protons or neutrons, it becomes unstable.

Pioneering prehistoric landscape reconstruction reveals early dinosaurs lived on tropical islands
Pioneering prehistoric landscape reconstruction reveals early dinosaurs lived on tropical islands
A new study using leading edge technology has shed surprising light on the ancient habitat where some of the first dinosaurs roamed in the UK around 200 million years ago. The research, led by the University of Bristol, examined hundreds of pieces of old and new data including historic literature vividly describing the landscape as a “landscape of limestone islands like the Florida Everglades?

Unique evidence links meteorite impact in Mexico to global extinction
Unique evidence links meteorite impact in Mexico to global extinction
Researchers find asteroid dust in impact crater that signalled end of dinosaurs VUB professor Steven Goderis and his team have published unique evidence linking the extinction of dinosaurs to the impact of an asteroid 66 million years ago. For the first time, the scientists found evidence of dust remnants from an asteroid in the Chicxulub impact crater itself in Mexico.

Forests' long-term capacity to store carbon is dropping in regions with extreme annual fires
Forests’ long-term capacity to store carbon is dropping in regions with extreme annual fires
Researchers have analysed decades' worth of data on the impact of repeated fires on ecosystems across the world. Their results, published today in the journal Nature Ecology and Evolution , show that repeated fires are driving long-term changes to tree communities and reducing their population sizes.

Green fuels for aviation
Green fuels for aviation
Researchers at the Paul Scherrer Institute PSI and the partner institute Empa have started a joint initiative called SynFuels. The goal is to develop a process for producing kerosene from renewable resources. In this way liquid fuel mixtures of the highest quality, which would allow the most residue-free combustion possible and thus be suitable for aircraft propulsion, should be obtainable using carbon dioxide and hydrogen from renewable resources.

Copepods can find mates even in turbulent conditions
Copepods can find mates even in turbulent conditions
Copepods (minute crustaceans with paddle-like feet) can differentiate between disturbances in water generated by nearby organisms and turbulence caused by wind or waves - an ability which helps them to find mates. It had previously been assumed that turbulent conditions would impede the quest for mates.

Using Submarine Cables to Detect Earthquakes
Seismologists at Caltech working with optics experts at Google have developed a method to use existing underwater telecommunication cables to detect earthquakes. The technique could lead to improved earthquake and tsunami warning systems around the world. A vast network of more than a million kilometers of fiber optic cable lies at the bottom of Earth's oceans.

Warmer and wetter climates amplify carbon release
Warmer and wetter climates amplify carbon release
Terrestrial ecosystems help mitigate climate change by absorbing large amounts of carbon from the atmosphere. A new study now confirms that changing climate conditions could reduce this effect because in warmer and wetter areas, carbon stored in the soil is released back into the atmosphere more quickly.

Important steps for transforming toxic molecules in air at low temperatures
Important steps for transforming toxic molecules in air at low temperatures
Recerca Air pollution from fuel combustion is one of the greatest environmental problems, especially in urban environments. In densely populated cities, the presence of nitrogen oxides, very small carbon particles, and carbon monoxide (CO) in the air seriously harms the human health and increases mortality.

Indian agriculture: Groundwater depletion could reduce winter cropped acreage significantly in years ahead
India is the world's second-largest producer of wheat and rice and is home to more than 600 million farmers. The country has achieved impressive food-production gains since the 1960s, due in part to an increased reliance on irrigation wells, which allowed Indian farmers to expand production into the mostly dry winter and summer seasons.
