Last month, Sophie Wilmès, the prime minister of Belgium, appeared in an online video to tell her audience that the COVID-19 pandemic was linked to the "exploitation and destruction by humans of our natural environment." Whether or not these two existential crises are connected, the fact is that Wilmès said no such thing. Produced by an organization of climate change activists, the video was actually a deepfake, or a form of fake media created using deep learning. Deepfakes are yet another way to spread misinformation—as if there wasn't enough fake news about the pandemic already.

Women are more concerned about COVID-19 than men, study finds
A Dartmouth-Gallup study finds that women are more concerned about COVID-19 than men, a difference that transcends party lines. This female perspective towards the pandemic may be overlooked due to the underrepresentation of women in the workplace that is compounded by an underrepresentation in politics, creating what the researchers refer to as a representational "double whammy" effect. The study's findings are published in Politics & Gender.

Ants adapt tool use to avoid drowning
Researchers have observed black imported fire ants using sand to draw liquid food out of containers, when faced with the risk of drowning. This is the first time this sophisticated tool use has been reported in animals. These findings are published in the British Ecological Society journal Functional Ecology.
Symptoms of COVID-19 are a poor marker of infection, new UK population study shows
86% of UK residents who tested positive for COVID-19 during lockdown did not have the specific virus symptoms (cough, and/or fever, and/or loss of taste/smell), finds a new study by UCL researchers. The authors say a more widespread testing programme is needed to catch 'silent' transmission and reduce future outbreaks.
Restricting supermarket promotions of high-sugar food and drinks reduces sales without reducing store profits
Restricting the promotion and merchandising of unhealthy foods and beverages leads to a reduction in their sales, presenting an opportunity to improve people's diets, according to a randomised controlled trial of 20 stores in remote regions of Australia published in The Lancet Planetary Health journal.
Comeback of drug-resistant neglected tropical disease tracked through genomic surveillance
Genome sequencing has shed light on the re-emergence of the bacterium that causes yaws, a neglected tropical disease of the skin, bones and joints. The re-emergence followed a mass drug administration (MDA) campaign that aimed to eliminate the disease in Papua New Guinea.
Pollinator monitoring more than pays for itself
