Rapid evolution in fish: genomic changes within a generation
Rapid evolution in fish: genomic changes within a generation
Researchers from Basel have identified the genetic basis of rapid adaptation using a native fish species. They compared threespine stickleback fish from different habitats in the Lake Constance region. Their study reveals that changes in the genome can be observed within a single generation. The results were published Communications.

RNA degradation contributes to gene silencing in higher eukaryotes
RNA degradation contributes to gene silencing in higher eukaryotes
The Gasser group discovered that silencing of heterochromatic regions - and more specifically of hundreds of Polycomb-target genes enriched for H3K27me3 - can occur through selective RNA degradation, and not only through transcriptional repression. The study links the epigenetics state of a gene with the fate of its RNA transcript.

A new therapeutic target turns the immune system against lymphoma
A new therapeutic target turns the immune system against lymphoma
EPFL scientists have identified a key mechanism that tumor cells use to take advantage of and avoid detection from the immune system. Targeting this mechanism offers a new therapeutic strategy for cancers like Non-Hodgkin lymphoma. Non-Hodgkin lymphoma (NHL) is a group of cancers that originate in the lymph nodes and affect white blood cells of the immune system called B cells.

A major step towards the explanation of the matter-antimatter asymmetry
A major step towards the explanation of the matter-antimatter asymmetry
The international T2K Collaboration has published results showing the strongest evidence to date implying the breaking of the symmetry between matter and antimatter in so-called neutrino oscillations. This is a major step towards the understanding of the dominance of matter over antimatter in the Universe.

Following the insect meltdown, numbers of orb web spiders have drastically declined
Following the insect meltdown, numbers of orb web spiders have drastically declined
The abundance of large orb web spiders in the Swiss midland has declined drastically over the last 40 years. The main reason for this is the shrinking food supply available to these insectivorous animals. This is demonstrated in a study conducted by researchers from the University of Basel and Ghent University (Belgium), as reported in the scientific journal Insects.

A material with a particular twist
A material with a particular twist
In a material made of two thin crystal layers that are slightly twisted with respect to each other, researchers at ETH have studied the behaviour of strongly interacting electrons. Doing so, they found a number of surprising properties. Many modern technologies are based on special materials, such as the semiconductors that are important for computers, inside of which electrons can move more or less freely.

Into drugs and vaccines to combat Covid-19
As the world anxiously awaits a remedy for the novel coronavirus, ETH Zurich is also involved in the search for active substances and vaccines. This overview sets out the therapeutic approaches pursued by ETH researchers. As yet, there is still no reliable treatment for Sars-CoV-2. However, scientists across Switzerland and worldwide are engaged in an intensive search for an effective agent against the pathogen responsible for the Covid-19 pandemic.

Pest Control with Genetically Modified Insects
Pest Control with Genetically Modified Insects
To control pests without pesticides, genetically modified organisms of the same species could be used. The latter carry a gene that is passed on with above-average frequency via sexual reproduction. This gene possesses traits that directly weaken the pest, or prevent pathogens from being transmitted.

Photonic microwave generation using on-chip optical frequency combs
Photonic microwave generation using on-chip optical frequency combs
Using integrated photonic chips fabricated at EPFL, scientists have demonstrated laser-based microwave generators. These microwave signals, as well as their optical carriers, could be used in radars, satellite communications and future 5G wireless networks. In our information society, the synthesis, distribution, and processing of radio and microwave signals are ubiquitous in wireless networks, telecommunications, and radars.

Towards a therapy against prostate cancer metastasis
An international group of researchers, led by the Institute of Oncology Research (IOR, affiliated to USI), has discovered a mechanism to recognise the cancer cells responsible for prostate cancer and selectively eliminate them. The study was published on April 6 by the Journal of Clinical Investigation (JCI).

Sleeping Sickness Elimination at a Crossroads
Sleeping Sickness Elimination at a Crossroads
Human African trypanosomiasis, also known as HAT or sleeping sickness, is a vector-borne parasitic disease. Since the number of new cases reported between 2000 and 2018 dropped by 95%, the World Health Organization (WHO) targeted its elimination as a public health problem by 2020 and interruption of transmission (zero cases) for 2030; but there is still much work to be done.

Analyses for getting to grips with the pandemic
Analyses for getting to grips with the pandemic
ETH researchers are developing and improving methods to detect the pandemic virus or virus-specific antibodies. With the help of such tests, the scientists are also investigating the details of how the pathogen is spreading. A project overview. Even though the first wave of the COVID-19 pandemic has passed its peak in Switzerland, coronavirus diagnostic procedures are as important as ever.

CHEOPS space telescope ready for scientific operation
The CHEOPS space telescope has exceeded scientists' expectations for accuracy. CHEOPS has reached its next milestone: Following extensive tests in Earth's orbit, some of which the mission team was forced to carry out from home due to the coronavirus crisis, the space telescope has been declared ready for science.

How exercise supports your mental fitness: current recommendations
Sporting activities can bring about a long-term improvement in cognitive performance across all age groups. However, the effects differ between men and women, and not all sports provide the same impact. Researchers at the University of Basel and the University of Tsukuba have provided recommendations based on a comprehensive analysis of previous studies.

Astronomy: six planets (almost) in rythm
An international team lead by researchers of the University of Geneva has discovered a six-planets system. Almost visible to the naked eye in the Draco constellation, the star HD 158259 has been observed for the last seven years by astronomers using the SOPHIE spectrograph. This instrument, installed at the Haute-Provence Observatory in the South of France, acquired three hundred measurements of the star.

Certain immune cells have different jobs depending on the organ
Group 3 innate lymphoid cells are immune cells that function differently depending on the organ: in the intestines, they prevent certain immune responses, whereas in the spleen they stimulate them. Researchers from the University of Basel have discovered how signals from the surrounding tissue control this.

Artificial intelligence accelerates blood flow MRI
Imaging technology helps to detect cardiovascular diseases much earlier; however, precise examinations are still very time-consuming. Researchers from ETH and the University of Zurich have now presented a method that could greatly accelerate dynamic magnetic resonance imaging of blood flow. "Thanks to this innovation, quantitative magnetic resonance imaging could make tremendous progress," says Sebastian Kozerke, Professor of Biomedical Imaging at ETH and the University of Zurich.
