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
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
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
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
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.

Controlled genome editing moves a step closer
Scientists at EPFL have developed an artificial protein that can keep the CRISPR genome-editing tool on its tracks. The research appears in a paper Chemical Biology A team at EPFL's Laboratory of Protein Design & Immunoengineering (LDPI), led by Professor Bruno Correia, working with Dominik Niopek's lab at Heidelberg University Hospital and the BioQuant Center, Heidelberg, Germany, have designed a protein (AcrX in short), using computational approaches, that can control CRISPR genome-editing in human cells.

A new approach to improve biological control agents of agricultural pests
A new approach to improve biological control agents of agricultural pests
In a new study, researchers from the University of Bern developed an experimental approach that may be used to improve a wide range of organisms that rely on microbial symbionts to control insect pests. This approach opens up a new avenue for the improvement of biological control strategies towards a more sustainable, pesticide-free agriculture.

Computer modelling deciphers the important role of the river-groundwater interface as a hot spot for arsenic release
Computer modelling deciphers the important role of the river-groundwater interface as a hot spot for arsenic release
Naturally occurring (geogenic) arsenic contamination in groundwater is a problem of global significance, with noteworthy occurrences in large parts of the alluvial and deltaic aquifers in South and Southeast Asia. Computer models are necessary to analyse field observations, to unravel which chemical and physical processes play a role, and to predict the behaviour of arsenic within aquifers - namely where and when pollution may occur in the future.

Cleaner air with geothermal energy
Cleaner air with geothermal energy
The use of dirty coal as a heat source makes life tough in the Mongolian winter. ETH geophysicists are helping to develop geothermal energy as a clean alternative. Many Europeans have an idyllic view of Mongolia as a land of wide, empty spaces and pristine nature. But the truth is more complicated, especially in winter.

Evaluates the effects of the COVID-19 lockdown on well-being
A new nationwide study being conducted jointly by EPFL, the Idiap Research Institute and the University of Lausanne (UNIL) aims to understand the emotional effects of the lockdown on Swiss residents and what steps they are taking to cope with it. The findings will be used to develop better support strategies for the future.

How artificial intelligence can help to design new drugs
How artificial intelligence can help to design new drugs
Traditional methods for predicting interactions between proteins and other molecules rely on complex supercomputer simulations. Instead, a group of researchers from EPFL and USI developed a new artificial intelligence system that analyzes the 3D structure of protein surfaces. The new method MaSIF (Molecular Surface Interaction Fingerprinting) is a collaboration between the EPFL Protein Design & Immunoengineering lab (headed by Prof. Bruno Correia) and the group of Michael Bronstein , professor at USI and Imperial College of London, and head of research in Graph Learning at Twitter.

Agriculture began in the Amazon 10’000 years ago
As a new study shows, more than 10,000 years ago, people in the southwest of the Amazon began growing manioc and squash, 8,000 years earlier than previously thought. The area is thus one of the early Holocene centres of plant domestication in the world. People also changed the landscape by creating thousands of so-called forest islands.

Measures are having an impact
Measures are having an impact
The "lockdown light" decreed by the Swiss Federal Council has led to each person infected with Sars-CoV-2 going on to infect only one person on average instead of two or three prior to the lockdown, as calculations by a team from ETH Zurich have shown. This means the situation is stable, but the epidemic has yet to be contained.
