Changes in oceanographic fronts affect the gene flow among marine crab populations
Changes in oceanographic fronts affect the gene flow among marine crab populations
In the Mediterranean and the Atlantic, the intensity and location of the oceanographic fronts that limit the gene connectivity among populations of marine crabs vary over time. These dynamic changes, described in an article published in the journal Scientific Reports , alter the gene structure of the populations of marine crabs of commercial and gastronomic interest.

Long-term liquid water also on non-Earth-like planets?
Long-term liquid water also on non-Earth-like planets?
Liquid water is an important prerequisite for life to develop on a planet. As researchers from the University of Bern, the University of Zurich and the National Centre of Competence in Research (NCCR) PlanetS report in a new study, liquid water could also exist for billions of years on planets that are very different from Earth.

Defects in quartz crystal structure reveal the origin of dust
Defects in quartz crystal structure reveal the origin of dust
Global warming and a progressively drier climate in many parts of the world are causing more dust storms. To predict how these storms are caused, researchers are looking into the past to understand where the dust came from, for how long, and over what distances it was transported. An international research team led by Dr. Aditi K. Dave and Professor Kathryn Fitzsimmons from the Department of Geosciences at the University of Tübingen, along with colleagues from Romania, Brazil, Kazakhstan and Tajikistan, have now developed a new method of doing this.

Climate warming causes new rivers to form on the surface of the Greenland ice sheet
Climate warming causes new rivers to form on the surface of the Greenland ice sheet
Using more than 25'000 satellite images, Andrew Tedstone and Horst Machguth, two researchers from the University of Freiburg, have observed that the runoff of water from the melting of the Greenland ice sheet has increased significantly in recent years. This phenomenon, caused by global warming, contributes to a 1 mm rise in sea level each year .

Huge pool of heat in the Pacific caused by climate change
A long-term warm water body that continues to warm has now been discovered by a team from the CLICCS Cluster of Excellence at the University of Hamburg. It is three million square kilometers in size, is due to the human-induced increase in greenhouse gases, and favors extreme heat waves in the Northeast Pacific.

No signs (yet) of life on Venus
No signs (yet) of life on Venus
The unusual behaviour of sulphur in Venus- atmosphere cannot be explained by an -aerial- form of extra-terrestrial life, according to a new study. Even if -our- Venus is dead, it-s possible that Venus-like planets in other systems could host life Paul Rimmer Researchers from the University of Cambridge used a combination of biochemistry and atmospheric chemistry to test the -life in the clouds- hypothesis, which astronomers have speculated about for decades, and found that life cannot explain the composition of the Venusian atmosphere.

Scientists provide explanation for exceptional Tonga tsunami
Scientists say they have identified the exact mechanism responsible for the exceptional tsunami that spread quickly across the world after the colossal eruption of the Tonga volcano earlier this year. In a new paper , an international team including researchers from Cardiff University say the exceptional event was caused by acoustic-gravity waves (AGWs) triggered by the powerful volcanic blast, which travelled into the atmosphere and across the ocean as the Hunga Tonga-Hunga Ha'apai volcano erupted.

Ground-breaking number of brown dwarfs discovered
Ground-breaking number of brown dwarfs discovered
Brown dwarfs, mysterious objects that straddle the line between stars and planets, are essential to our understanding of both stellar and planetary populations. However, only 40 brown dwarfs could be imaged around stars in almost three decades of searches. An international team led by researchers from the Open University and the University of Bern directly imaged a remarkable four new brown dwarfs thanks to a new innovative search method.

Researches decipher the migratory pattern of the smallest seabird in the Mediterranean
Researches decipher the migratory pattern of the smallest seabird in the Mediterranean
It had always been thought that the Mediterranean population of the European storm petrel —the smallest seabird in the Mediterranean— spent the year in this sea and that only a small part of the population migrated to the Atlantic during the winter season. Now, a study reveals that most of the European storm petrels that nest in the western Mediterranean move to the Atlantic Ocean as their main wintering area.

Scientists explain why Uranus and Neptune are different colours
Scientists explain why Uranus and Neptune are different colours
Layers of haze particles are responsible for the different blue hues of the ice giants Neptune and Uranus. Neptune and Uranus have much in common - they have similar masses, sizes, and atmospheric compositions - yet Neptune looks distinctly bluer than its planetary neighbour Uranus. New research led by Professor Patrick Irwin, Department of Physics , University of Oxford suggests that a layer of haze that exists on both planets is behind the different hues of blue.

Water treatment plants would be ready for the removal of nanoplastics
Water treatment plants would be ready for the removal of nanoplastics
The biologically active, slow-flow sand filters of lake water treatment would remove nanoplastics from the raw water very efficiently. This was shown both in the laboratory and in larger, realistic tests and modelling. It's a hot topic, at least on social media: tiny plastic particles allegedly end up not only in oceans and lakes, but also in drinking water - and, yes, even in bottled mineral water.
