Argentine ants will do anything for sugar, but they won't do this
Argentine ants will do anything for sugar, but they won’t do this
Key takeaways Argentine ants have been able to displace native ant species in large part because of their aggressive foraging for sugar and other carbohydrates. However, when they've been deprived of food and competitors are present, they significantly limit their foraging activity instead of vigorously pursuing food.

Decoy products influence our decisions
Decoy products influence our decisions
When people have the choice between two products, a third option can influence their decision by shifting their focus. Researchers from the University of Basel have shown, however, that whether one object is preferred over another depends on which visual features are being used to form an opinion. We know all too well that we can often be distracted by certain special offers as we shop.

New Virus Discovered in Swiss Ticks
New Virus Discovered in Swiss Ticks
The Alongshan virus was discovered in China only five years ago. Now researchers at the University of Zurich have found the novel virus for the first time in Swiss ticks. It appears to be at least as widespread as the tickborne encephalitis virus and causes similar symptoms. The UZH team is working on a diagnostic test to assess the epidemiological situation.

Fighting cancer is more efficient at dawn
Fighting cancer is more efficient at dawn
Scientists from the UNIGE and LMU show that the anti-tumour activity of the immune system - and the effectiveness of cancer immunotherapies - depends on the time of day. The ability of tumours to take hold and grow depends, among other things, on the effectiveness of the immune system in fighting them.

Unexpected speed-dependent friction
Unexpected speed-dependent friction
In the macro world, friction doesn't depend on the speed at which two surfaces move past one another, but researchers from Basel and Tel Aviv have now observed precisely this effect in special graphene structures on a platinum surface. December 2022 Due to their low-friction properties, materials consisting of single atomic layers are of great interest for applications where the aim is to reduce friction — such as hard disks or moving components for satellites or space telescopes.

Ultrafast writing with light
Youri van Hees defended his PhD thesis at the department of Applied Physics on December 7th. Due to the ever-increasing growth of our data consumption, researchers are looking for faster, more efficient, and more energy-conscious data storage techniques.

Humans struggle to identify aggression in dogs, other humans
Humans struggle to identify aggression in dogs, other humans
Researchers showed participants videos of human, dog, and macaque pairs to determine how well humans assess social interactions As a species, humans are constantly interpreting signals to assess social situations and make predictions about what could happen next. Being able to tell if someone else, whether human or animal, is happy with us, about to get aggressive, or even paying attention, can have major evolutionary advantages.

Novel technology for detecting and identifying traces of micro and nano plastics in consumable water
Micro and nano plastics are everywhere: in the air, in seas and rivers, in soil, and in plants and animals.

The three dimensions of a flower
The three dimensions of a flower
Montreal biologists publish a study demonstrating that photogrammetry allows rapid and precise three-dimensional reconstruction of flowers from two-dimensional images. CONTENU - To better understand the evolution of flowers, a research team in biology from Université de Montréal, the Montreal Botanical Garden and McGill University have succeeded in using photogrammetry to quickly and precisely build, in three dimensions, a model of a flower from two-dimensional images.

Anatomical barriers shield the brain from SARS-CoV-2 invasion at vulnerable interfaces
Anatomical barriers shield the brain from SARS-CoV-2 invasion at vulnerable interfaces
Absence of evidence for neurotropism and neuroinvasion of several SARS-CoV-2 variants including Omicron A common symptom of COVID-19 is a partial or complete loss of smell. The virus infects sustentacular cells in the olfactory epithelium and is thought to impair thereby the activity of the sensory neurons in this epithelium.

KU Leuven researchers put octopus brain on the map
KU Leuven researchers put octopus brain on the map
Wide variation in brain cells makes octopus brain even more complex than thought For the first time, researchers are mapping the different cell types found in octopus brains. Because of these animals' amazing ability to think, it should come as no surprise that their brain cells exhibit similar properties to the known neurons and glia in other animals.

Using light to manipulate neuron excitability
A new optogenetics-based tool allows researchers to control how neurons respond to electrical input. Nearly 20 years ago, scientists developed ways to stimulate or silence neurons by shining light on them. This technique, known as optogenetics, allows researchers to discover the functions of specific neurons and how they communicate with other neurons to form circuits.

Energy-efficient computing with tiny magnetic vortices
Unconventional computing combines Brownian computing with reservoir computing / First prototype developed A large percentage of energy used today is consumed in the form of electrical power for processing and storing data and for running the relevant terminal equipment and devices. According to predictions, the level of energy used for these purposes will increase even further in the future.

'Collective reflection needed for way out of crisis Alzheimer's research'
’Collective reflection needed for way out of crisis Alzheimer’s research’
A vast amount of money is involved in Alzheimer's disease research. However, scientists have been unable to achieve substantial clinical results in recent decades. In a recent analysis of the situation, Utrecht University historian of science Bert Theunissen and his colleague from Erasmus University Rotterdam Noortje Jacobs now argue that a deadlock has developed that makes progression unlikely.

Short-lived Ice Streams
Short-lived Ice Streams
Major ice streams can shut down, shifting rapid ice transport to other parts of the ice sheet, within a few thousand years. This was determined in reconstructions of two ice streams, based on ice-penetrating radar scans of the Greenland ice sheet, that a team of researchers led by the Alfred Wegener Institute, in which the University of Tübingen is also involved, has just presented in the journal Nature Geoscience.

Significant improvements in NHS care for orthopaedic patients over last decade
There have been significant improvements in care for patients undergoing hip and knee surgery through the NHS over the past 10 years, finds a new study led by UCL researchers. The study, published in BMJ Open, set out to evaluate the impact of Getting it Right First Time (GIRFT) , a national NHS improvement programme which started in 2012.

New X-ray technology can improve Covid-19 diagnosis
Patient study demonstrates benefits of dark-field X-ray technology A research team at the Technical University of Munich (TUM) has, for the first time, produced dark-field X-ray images of patients infected with the corona virus. In contrast to conventional X-ray images, dark-field images visualize the microstructure of the lung tissue, thereby providing additional information.

Emergency medicine: Correlation between electrolyte administration in atrial fibrillation and return to regular heartbeat
Patients receiving emergency medical treatment for atrial fibrillation show a correlation between the intravenous administration of potassium and magnesium and a spontaneous return to a normal heart rhythm. This was discovered in a new study by the Department of Emergency Medicine at MedUni Vienna and University Hospital Vienna, which analysed patient data between 2009 and 2020.

Alpine bacterial strain adapts to the change of seasons
Alpine bacterial strain adapts to the change of seasons
Scientists have discovered for the first time a bacterium in Lake Gossenköllesee in Tyrol that uses two different mechanisms to obtain energy from light. This could be an adaptation to the very pronounced change of seasons in the Alps. The change of seasons is clearly noticeable in the Alps. Moderate temperatures with a high exposure to light in summer give way to months with great cold and only little sunlight in winter.
