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%.

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
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
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
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.
