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.

Unselfish behavior has evolutionary reasons
Unselfish behavior has evolutionary reasons
Altruistic behavior is often seen as an exclusively human characteristic. However, behavioral research has uncovered numerous examples of altruistic behavior in the animal kingdom. In a new study, researchers at the University of Bern show that animals that help others -selflessly- to raise their young generate an evolutionary advantage.

Cancer: the double advantage of killer T-cells
Cancer: the double advantage of killer T-cells
Scientists highlight the unexpected effect of certain immunotherapies to prevent cancer metastases. To grow, tumours rely on a specific structure, the tumour stroma. This includes blood vessels, which provide the nutrients necessary for the multiplication of diseased cells, and of lymphatic vessels, through which they migrate to metastasise.

Olfactory neurons adapt to the surrounding environment
Olfactory neurons adapt to the surrounding environment
A team from the UNIGE has highlighted the great variability and continuous adaptation of olfactory neurons. Olfactory receptors, present on the surface of sensory neurons in the nasal cavity, recognize odorant molecules and relay this information to the brain. How do these neurons manage to detect a large variability of signals and adapt to different levels of stimulation? A joint team from the Faculty of Science and the Faculty of Medicine of the University of Geneva investigated the gene expression profile of these neurons in the presence or absence of odorant stimulation.

A drone for ultrafast transitions between air and water
A drone for ultrafast transitions between air and water
A new robot is capable of switching from an underwater drone to an aerial vehicle in less than one second. The robot also features a suction disc inspired by the remora fish, which enables it to hitchhike on wet or dry moving objects to significantly reduce its power consumption. It is designed for biological and environmental monitoring in marine ecosystems such as surveying ocean pollution in the open sea as the scientist of Beihang University, Imperial College London and Empa point out in a new study published in Science Robotics.

From the packet into your food: what harmful substances are in food packaging?
Salad boxes to go, sealed-tray lasagna and apple juice in PET bottles: we encounter packaged food and drink everywhere. A new database shows which packaging contains harmful substances that can be transferred to its contents. It also includes findings from researchers at the University of Basel, who are investigating plastic molecules that were previously unknown or barely known.

Dolphins Line Up to Self-Medicate Skin Ailments at Coral ’Clinics’
If a human comes down with a rash, they might go to the doctor and come away with some ointment to put on it. Indo-Pacific bottlenose dolphins get skin conditions, too, but they come about their medication by queuing up nose-to-tail to rub themselves against corals. In the journal iScience on 19 May, researchers show that these corals have medicinal properties, suggesting that the dolphins are using the marine invertebrates to medicate skin conditions.

New findings on the global cooling of 1627 BC
New findings on the global cooling of 1627 BC
An interdisciplinary study, in which the University of Bern played a major role, sheds new light on two extreme volcanic events and a subsequent global cooling in antiquity. With the help of a highly precise analysis of volcanic ash and sulphur in ice cores from Greenland and Antarctica, it became clear that the global cooling around 1627 BC was not attributable to the Thera volcano in Santorini, as previously assumed, but to a volcano in distant Alaska.

Change of temperature causes whole body reprogramming
Scientists have discovered that changes in temperature cause marked and organ-specific effects in all tissues. Human beings, like most organisms, are constantly exposed to alternating colder or warmer temperatures. These environmental variations cause striking metabolic effects and require constant adaptations.

A new calculation for predicting fusion energy
Physicists at EPFL, within a large European collaboration, have revised one of the fundamental laws that has been foundational to plasma and fusion research for over three decades, even governing the design of megaprojects like ITER. The update shows that we can actually safely use more hydrogen fuel in fusion reactors, and therefore obtain more energy than previously thought.
