Lipid Metabolism Controls Brain Development
Lipid Metabolism Controls Brain Development
A lipid metabolism enzyme controls brain stem cell activity and lifelong brain development. If the enzyme does not work correctly, it causes learning and memory deficits in humans and mice, as researchers at the University of Zurich have discovered. Regulating stem cell activity via lipid metabolism could lead to new treatments for brain diseases.

Prostate cancer treatment may protect from COVID-19
Androgen-deprivation therapy could protect against infection with SARS-CoV-2 and against severe disease progression. This is suggested by a study led by a professor from the Università della Svizzera Italiana and ETH Zurich. Male cancer patients have a 1.8-fold increased risk of COVID-19 infection compared to the whole male population and develop a more severe disease.

Filtering out toxic chromium from water
EPFL chemists have developed sponges to capture various target substances, like gold, mercury and lead, dissolved in solution. The sponges are actually porous crystals called metal organic frameworks, and now one exists for capturing toxic hexavalent chromium from water. Hexavalent chromium continues to contaminate water sources around the world, with one US company fined just this February for having put employees at risk.

Going against the trend
Going against the trend
Global warming has affected the entire planet's surface, except for one particular area of the ocean, which has bucked the trend. A research team comprising scientists from ETH Zurich and Princeton University has unravelled the causes of this conundrum. Climate and marine scientists are observing pervasive warming of the ocean and the land surfaces across the globe.

Workers Happy despite Crisis and Uncertainty
Workers Happy despite Crisis and Uncertainty
In general, workers in Switzerland and Germany are coping well with the Covid-19 crisis and the associated social disruption. They are feeling happier and finding it easier to unwind and balance work and private life. They are also more engaged at work than last year, a survey among 600 participants carried out by researchers of the University of Zurich shows.

Long-term developments of energy pricing and consumption in industry
Long-term developments of energy pricing and consumption in industry
Researchers at the Paul Scherrer Institute PSI have collaborated with British economists to study how energy consumption by Swiss industry develops depending on energy pricing. To this end, they examined in particular the prices and consumption of both electricity and natural gas over the past decades.

Bacterial behaviour influences cloud formation
Bacterial behaviour influences cloud formation
ETH researchers have analysed individual marine bacterial cells to show that metabolic processes inside them determine the amount of gas they release, which is involved in cloud formation. Meteorologists have known for almost 50 years that the proverbial flapping of a butterfly's wings can trigger a hurricane in a completely different location.

Protective shield: How pathogens withstand acidic environments in the body
Protective shield: How pathogens withstand acidic environments in the body
Certain bacteria, including the dangerous nosocomial pathogen MRSA, can protect themselves from acidic conditions in our body and thus ensure their survival. Researchers at the Biozentrum of the University of Basel have now elucidated an important mechanism in this process. A transport protein involved in cell wall biosynthesis plays a key role, they report Structural & Molecular Biology.

Bern coronavirus clone goes "viral"
Researchers in virology and veterinary bacteriology at the University of Bern have cloned the novel coronavirus (SARS-CoV-2). The synthetic clones are being used by research groups worldwide to test corona samples, find antiviral drugs and develop vaccines as quickly as possible. The method developed in Bern can also be used in future to combat other highly infectious viruses.

Epidiemology and urban planning: the views of Sascha Roesler on the NZZ
What is the relationship between epidiemology and urban planning? Sascha Roesler, assistant professor at the USI Academy of Achitecture (Institute for the History and Theory of Art and Architecture, ISA), explores the subject in a recently published article in the Neue Zürcher Zeitung and with a short video, showing how these two concepts have a common history and future.

Predators Help Prey Adapt to an Uncertain Future
Predators Help Prey Adapt to an Uncertain Future
What effect does extinction of species have on the evolution of surviving species' Evolutionary biologists have investigated this question by conducting a field experiment with a leaf galling fly and its predatory enemies. They found that losing its natural enemies could make it more difficult for the prey to adapt to future environments.

Coronavirus lockdown: Every second person feels more stressed
Coronavirus lockdown: Every second person feels more stressed
A survey by the University of Basel of over 10,000 people from throughout Switzerland has shown that around half of respondents feel more stressed in lockdown than they did before the coronavirus crisis. In the lockdown phase under study, the frequency of severe depressive symptoms almost tripled. On the other hand, 26% of respondents reported a drop in stress during lockdown.

In search of the lighting material of the future
In search of the lighting material of the future
At the Paul Scherrer Institute PSI, researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). The substance enables high light yields and would be inexpensive to produce on a large scale - that means it is practically made for use in large-area room lighting.

Covid-19: using wastewater to track the pandemic
EPFL researchers, working in association with the Swiss Federal Institute of Aquatic Science and Technology (Eawag), have developed a method for detecting the novel coronavirus in wastewater samples. Their method has been tested successfully on samples collected during the first phase of the pandemic, paving the way to an early-stage warning system.

Tracking the course of the pandemic in wastewater
"Detection and quantification of SARS-CoV-2 in wastewater" - research projects on this scale generally take several years. But now, thanks to major efforts, a group of scientists led by Professor Tamar Kohn (Environmental Chemistry Laboratory) at EPFL and Dr Christoph Ort (Urban Water Management) and Dr Tim Julian (Environmental Microbiology) at Eawag have shown that an idea like this can be realised within a matter of weeks.

High Cost of Cancer Drugs Not Always Justified
High Cost of Cancer Drugs Not Always Justified
Do high prices of some cancer medicines have a higher benefit than those drugs with lower prices' An international UZH study has concluded that, in general, there is no correlation between costs of a cancer drugs and their clinical benefit. The researchers are therefore calling for the clinical benefit of drugs to be better reflected in pricing.

Conversion product of painkiller more toxic than expected
Conversion product of painkiller more toxic than expected
Every day, several tons of pharmaceutical ingredients are released into bodies of water worldwide. These originate mainly from domestic wastewater, because most substances are excreted again after ingestion - in part unchanged. Since many wastewater treatment plants do not retain all substances without leaving any residues, the rest ends up in the aquatic environment.

Why does COVID-19 affect old people more than young people?
Why does COVID-19 affect old people more than young people?
As we age, our lung tissue becomes stiffer - and this is a phenomenon that SARS-CoV-2 may be exploiting. Caroline Uhler and G. V. Shivashankar outline their hypothesis. The new coronavirus strikes both young and old. But the more severe cases and the higher rates of death are among the elderly.

Containment measures avoid 200,000 hospitalizations in Italy
Containment measures avoid 200,000 hospitalizations in Italy
Researchers have modeled the effects of containment and social distancing measures implemented by the Italian government to prevent the spread of COVID-19. Their findings show that contagion transmission was reduced by 45% in March. The model will now be used to analyze possible future scenarios. Since the beginning of the COVID-19 pandemic, mobility restrictions and social distancing measures implemented by the Italian government have avoided at least 200,000 hospitalizations and, over time, reduced contagion transmission by 45%.
