Escort service: The role of immune cells in the formation of metastases
Tumor cells use a certain type of immune cells, the so-called neutrophils, to enhance their ability to form metastases. Scientists have deciphered the mechanisms of this collaboration and found strategies for blocking them. This is reported by researchers from the University of Basel and the University Hospital of Basel in the scientific journal "Nature".

Morals versus Money: How We Make Social Decisions
Our actions are guided by moral values. However, monetary incentives can get in the way of our good intentions. Neuroeconomists at the University of Zurich have now investigated in which area of the brain conflicts between moral and material motives are resolved. Their findings reveal that our actions are more social when these deliberations are inhibited.

Fine-tuning gene regulation by CG dinucleotides
Fine-tuning gene regulation by CG dinucleotides
Transcription of our genes mostly begins in regions of the genome called CpG islands. These are rich in the dinucleotide CpG (thus the name), critical for gene activity and devoid of DNA methylation. Despite the relevance of CpG islands, it is unclear if the CpG dinucleotide itself contributes to their activity.

Even psychological placebos have an effect
Even psychological placebos have an effect
Placebo effects do not only occur in medical treatment - placebos can also work when psychological effects are attributed to them. Psychologists from the University of Basel reported these findings in the journal Scientific Reports, based on three studies with over 400 participants. Psychotherapy and placebos are both psychological interventions that not only have comparable effects, but that are also based on very similar mechanisms.

Precious metal tracks nanoplastics
Precious metal tracks nanoplastics
Tiny plastic particles measuring about 100 nanometres (millionths of a millimetre) are used in many products, for example to encapsulate dye or aromatic substances or as additives to shampoos and cosmetics. Many of them land directly in sewage as soon as the products are used. Together with other plastics, for example from tyre rubber in road run-off, they end up in the water-treatment plants.

Monthly wages are an important step towards economic development
Across developing economies, most workers and agricultural producers are paid are paid on a daily basis. This has a negative impact on their ability to generate savings for large expenses. Researchers from UZH show dairy farmers and agricultural workers prefer to be paid once at the end of the month, rather then daily, because monthly payments schemes are an efficient tool to increase saving.

Bringing technologies from the laboratory to industry
Innovations are the driving force behind the Swiss economy. But how does an idea become an innovation, a real market success' Too many ideas from research laboratories fall by the wayside on their path to industrial implementation. They are caught in the so-called "Valley of Death" of the innovation process.

Intuition and failure are valuable ingredients in chemistry
Intuition and failure are valuable ingredients in chemistry
When researchers make a new discovery, they tend to only publish the results of their successful experiments. But just as informative are all the experiments that didn't work - the failed trials and incorrect hypotheses, which can offer important information. A team of EPFL chemists has developed a methodology for collecting those lessons and, crucially, sharing them with other researchers.

How Type 1 Diabetes Gradually Destroys Insulin Production
How Type 1 Diabetes Gradually Destroys Insulin Production
Using the new Imaging Mass Cytometry method, Zurich researchers have investigated the pancreas of healthy organ donors and those with type 1 diabetes. The study shows that many beta cells, which normally produce insulin, are still present in the early stages of the disease, but look very different. These beta cells could potentially be rescued for the benefit of the patient and the progression of the disease could be slowed down or even stopped.

Learning new vocabulary during deep sleep
Learning new vocabulary during deep sleep
Researchers of the University of Bern, Switzerland, showed that we can acquire the vocabulary of a new language during distinct phases of slow-wave sleep and that the sleep-learned vocabulary could be retrieved unconsciously following waking. Memory formation appeared to be mediated by the same brain structures that also mediate wake vocabulary learning.

A small fish provides insight into the genetic basis of evolution
A small fish provides insight into the genetic basis of evolution
A genetic analysis of sticklebacks shows that isolated populations in similar environments develop in comparable ways. The basis for this is already present in the genome of their genetic ancestors. Evolutionary biologists from the University of Basel and the University of Nottingham report these insights in the journal Evolution Letters.

Cancer: A mutation that breaks gene interplay in 3D
Cancer: A mutation that breaks gene interplay in 3D
EPFL scientists have discovered how a mutated gene can affect the three-dimensional interactions of genes in the cell, leading to various forms of cancer. Inside the cell, DNA is tightly wrapped around proteins and packed in a complex, 3D structure that we call "chromatin". Chromatin not only protects our genetic material from damage, but also organizes the entire genome by regulating the expression of genes in three dimensions, unwinding them to be presented to the cell's gene-expression machinery and then winding them back in.

New method to determine how safe buildings are after an earthquake
New method to determine how safe buildings are after an earthquake
EPFL scientists have developed a new method for evaluating building safety after an earthquake, helping residents return to their homes more quickly. Deciding when it's safe for a building's residents to move back in after an earthquake is a major challenge and responsibility for civil engineers. Not only do they have to evaluate whether the building could collapse, but also whether it could withstand aftershocks of the same magnitude.

Inequality promotes deforestation in Latin America
Inequality promotes deforestation in Latin America
Agricultural expansion is the main cause of deforestation in Latin America. Improvements in agricultural productivity can either enable forest conservation, or promote more deforestation. A new University of Bern study highlights the role played by inequality: high inequality leads to more deforestation, while lower inequality improves the long-term protection of remaining tropical forests.
