How the COVID-19 virus makes itself more infectious
How the COVID-19 virus makes itself more infectious
Scientists at EPFL have uncovered a cunning strategy that SARS-CoV-2, the virus that causes COVID-19, uses to increase its infectivity. SARS-CoV-2, the novel coronavirus first identified in late 2019, has since spread globally, leading to the COVID-19 pandemic that has affected millions. As countries grapple with its health, social, and economic impacts, scientists and researchers worldwide have been working tirelessly to understand the virus better and develop effective treatments and vaccines.

A new EPFL tool shows the decline of political tone in the US
A new EPFL tool shows the decline of political tone in the US
A new EPFL developed tool, Quotebank , has helped researchers provide the first large-scale data-driven evidence of a drastic shift towards a more negative political tone beginning at the start of Donald Trump's primary campaign in June 2015. A vast majority of Americans believe that the tone and nature of political debate in the United States has become more negative in recent years and more than half have the impression that Donald Trump is responsible.

Rapid early detection of drug resistance in cancer patients
Rapid early detection of drug resistance in cancer patients
Parithera, an EPFL spin-off, has developed a system that lets doctors detect drug resistance in cancer patients early on, saving precious time and preventing the unnecessary use of treatments with onerous side effects. Drug resistance is a major problem in the treatment of cancer. Some cancer cells demonstrate resistance right at the start of a new therapy, while others develop it over the course of several months or years.

Ultrathin films achieve record hydrogen separation
Ultrathin films achieve record hydrogen separation
Scientists at EPFL have synthesized the first ever metal-organic frameworks membrane with thickness of just one unit cell. The ultrathin film yields record-high separation performance of hydrogen-nitrogen. Metal-organic frameworks (MOFs) are a class of materials that contain nano-sized pores. These pores give MOFs record-breaking internal surface areas, which make them extremely versatile for a number of applications: separating petrochemicals and gases , mimicking DNA , producing hydrogen , and removing heavy metals , fluoride anions , and even gold from water are just a few examples.
