Like humans, beluga whales form social networks beyond family ties  

A groundbreaking study is the first to analyze the relationship between group behaviors, group type, group dynamics, and kinship of beluga whales in 10 locations across the Arctic. Results show that not only do beluga whales regularly interact with close kin, including close maternal kin, they also frequently associate with more distantly related and unrelated individuals. Findings will improve the understanding of why some species are social, how individuals learn from group members and how ani

Why lopinavir and hydroxychloroquine do not work on COVID-19  

Lopinavir is a drug against HIV, hydroxychloroquine is used to treat malaria and rheumatism. Until recently, both drugs were regarded as potential agents in the fight against the coronavirus SARS-CoV-2. Researchers have now discovered that the concentration of the two drugs in the lungs of Covid-19 patients is not sufficient to fight the virus.

Neonatal exposure to antigens of commensal bacteria promotes broader immune repertoire  

Researchers have added fresh evidence that early exposure to vaccine-, bacterial- or microbiota-derived antigens has a dramatic effect on the diversity of antibodies an adult mammal will have to fight future infections by pathogens. This antibody diversity is called the clonal repertoire -- basically different single cells with distinct antibody potential that can multiply into a large clone of cells, all producing that distinct antibody.

Liquid metal synthesis for better piezoelectrics: Atomically-thin tin-monosulfide  

Scientists have applied liquid-metal synthesis to piezoelectrics, advancing future flexible, wearable electronics, and biosensors drawing their power from the body's movements. Piezoelectric materials such as atomically-thin tin-monosulfide (SnS) convert mechanical forces or movement into electrical energy. Along with their inherent flexibility, this makes them candidates for flexible nanogenerators in wearable electronics or internal, self-powered biosensors.

One of the questions in ageing research is whether chronic inflammation is a cause of aging, or a consequence of t
