Reusing face masks: are microwaves the answer?

Stanford researchers used millimeter-sized crystals from the 1959 eruption of Hawaii's Kilauea Volcano to test models that offer insights about flow conditions prior to and during an eruption.

Thanks to the pandemic, we know just how quickly food can disappear from supermarket shelves. But it is hard to gauge the vulnerability of our food production system as a whole to abrupt changes, such as those that could be caused by extreme events such as a nuclear war or massive volcanic eruptions.

Aircraft also make noise on approach, which is often underestimated. A research project involving Empa has shown that it is quite possible to reduce noise during approach, to avoid particularly loud approaches and at the same time to reduce fuel consumption. In the future, pilots shall receive software assistance to help them better manage the complex relationships between air traffic control, flight mechanics and environmental impact.

Repurposed antiviral drugs - remdesivir, hydroxychloroquine, lopinavir and interferon - to treat COVID-19 appear to have little or no effect on patients hospitalised for the disease, in terms of overall mortality, initiation of ventilation and duration of hospital stay. The interim findings from the WHO Solidarity trial, published in the New England Journal of Medicine (NEJM), followed 11,266 adults at 405 hospitals in 30 countries.

Early adulthood, a transitional life stage marked by major changes in social roles and responsibilities, can bring with it an increase of mental health problems. A team of McGill University researchers has found that young adults who perceived higher levels of social support reported fewer mental health problems.

Scientists at Berkeley Lab have contributed much to the field since the Dec. 4, 1930, letter that theorized this particle's existence
