A new study led by Tobias Züst from the Institute of Plant Sciences of the University of Bern shows that a pair of complementary chemical defenses evolved independently in wallflowers, shaped by co-evolution with local insects. A pair of chemicals used by wallflowers and their kin to ward off predators have evolved to complement each other, with one targeting generalist herbivores and the other targeting specialized herbivores that have become resistant to the generalist defense.
A recent publication by Florian Altermatt, a research group leader at Eawag and Professor of Aquatic Ecology at the University of Zurich, began as an address to a gathering of legal experts.
ETH researchers analysed various possibilities for reducing the net CO2 emissions of the chemical industry to zero. Their conclusion? The chemical industry can in fact have a carbon-neutral future. Switzerland's Federal Council has decided that the country should become carbon-neutral by 2050. This may be challenging as far as car traffic and the entire power sector are concerned, but not impossible - with systematic electrification and the exclusive use of carbon-neutral energy sources, for example.
Ethical challenges in the age of digitisation
The Neue Zürcher Zeitung recently published a paper on the ethical challenges of digitisation written by Peter Seele, economist, philosopher and professor of business ethics at USI Faculty of Communication, Culture and Society and Dirk Helbing, professor of Computational Social Science at ETH Zurich.

You were already collecting wastewater samples in Ticino weeks ago - why? Christoph Ort (environmental engineer): We have many years of experience in the measurement of illicit drugs in wastewater.
The MedCo system aims to facilitate medical research on pathologies - such as cancer and infectious diseases - by enabling secure computations on decentralized data. The unique software has recently been deployed at three Swiss hospitals. MedCo was first released in 2019 as the first operational system to protect sensitive patient data so that it can be used collectively for medical research.
All the media talk about the lack of certain products in the stores in connection with the Covid-19 pandemic.
Large open-water fish predators such as tunas or sharks hunt for prey more intensively in the temperate zone than near the equator. With this result, a study headed by Marius Roesti of the University of Bern is challenging a long-standing explanation for the distribution of biodiversity on our planet.
The bacteria that cause tuberculosis need iron to survive. Researchers at the University of Zurich have now solved the first detailed structure of the transport protein responsible for the iron supply. When the iron transport into the bacteria is inhibited, the pathogen can no longer grow. This opens novel ways to develop targeted tuberculosis drugs.
Four keywords to understand journalism during a pandemic
From newspapers to television, from the internet to social media, we experience an overload of information on the Covid-19 pandemic. Science journalism has become an important source to help individuals understand what is true and what is false. In this video Philip Di Salvo, a post-doc researcher at USI Institute of Media and Journalism, proposes four key words to comprehend what is happening to the media.

EPFL researchers have developed a device that can zoom in on previously invisible cells at the back of the eye. The technology could be extremely useful for ophthalmologists, in particular for detecting age-related macular degeneration early and assessing new treatment options. There is renewed hope for people with eyesight problems such as age-related macular degeneration, or AMD.
Researchers at EPFL have developed a nanodevice that operates more than 10 times faster than today's fastest transistors, and about 100 times faster than the transistors you have on your computers. This new device enables the generation of high-power terahertz waves. These waves, which are notoriously difficult to produce, are useful in a rich variety of applications ranging from imaging and sensing to high-speed wireless communications.
The EmoDémos project - led by the University of Geneva among children aged 7 to 12 years - has shown that playing an instrument in an orchestra can facilitate the acquisition of cognitive and emotional skills in two years.
Researchers from ETH Zurich and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have set a new world record: they 3D printed complex objects with higher cellulose content than that of any other additively manufactured cellulose-based parts. To achieve this, they used a clever trick.
Researchers have shown that the decline in cognitive abilities after 50 years of age results in a decline in physical activity, and that - contrary to what has been suggested by the literature to date - the inverse relationship is much weaker. Someone dies somewhere in the world every 10 seconds owing to physical inactivity - 3.2 million people a year according to the World Health Organisation (WHO).
Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.
A study conducted by med. Francesco Bertoni at the Institute of Oncology Research ( IOR , affiliated to USI) has shown that a specific combination of drugs is a potentially winning strategy in the fight against lymphomas. The results obtained in the laboratory have enabled the researchers at the Istituto Oncologico della Svizzera italiana ( IOSI ) to develop a clinical study together with the Swiss Group for Clinical Cancer Research ( SAKK ).
Climate change is threatening the world's coral reefs, and saving them all will prove impossible. A team from EPFL has developed a method for identifying corals with the greatest adaptive potential to heat stress. The research, published in the journal Evolutionary Applications, should support improved and better-targeted marine biodiversity conservation strategies.
How digital humanities can help in a pandemic
With the onset of the COVID-19 outbreak, there is a race against the clock to implement science-based measures to protect society's most vulnerable populations. Public engagement with data has never been more urgent, and as EPFL professor Robert West explains, digital humanities research has a key role to play.

The Tech4Dev program connects EPFL researchers with NGOs in order to develop technologies able to address specific needs in the global South and withstand local conditions. Four projects have been awarded grants following the first call for proposals. The global North and South have differing climates, economies and infrastructure.
