Integrating satellite and socioeconomic data to improve climate change policy

Bangladesh is on track to lose all of its forestland in the next 35-40 years, leading to a rise in CO2 emissions and subsequent climate change, researchers said. However, that is just one of the significant land-use changes that the country is experiencing. A new study uses satellite and census data to quantify and unravel how physical and economic factors drive land-use changes. Understanding this relationship can inform climate policy at the national scale in Bangladesh and beyond.

The answers vary depending on the degree of kinship, gender and the time of assessment. Mandrills, monkeys living in Equatorial Africa, may recognize facial features coding relatedness better than humans. Scientists showed by using up-to-date artificial intelligence (AI) that half-sisters, who have the same father look more alike than half-sisters who share the same mother. The paternal half-sisters also have closer social relationships with each other than unrelated mandrills. This result provided the first evidence suggesting that interindividual resemblance has been selected to signal paternal kinship.

Sugar turns brown algae into good carbon stores

Brown algae are important players in the global carbon cycle by fixing large amounts of carbon dioxide and thus extracting this greenhouse gas from the atmosphere. Moreover, because microbial decomposition of dead brown algae is slower than that of other marine plants, carbon dioxide fixed by brown algae remains much longer in the sea.

Hearts that drum together beat together

Researchers have found that in a structured group drumming task aspects of participants' heart function synchronized. In a subsequent improvisational drumming task, groups with high physiological synchrony in the structured task showed more coordination in drumming. The data show that behavioral synchronization and enhanced physiological synchronization while drumming each uniquely predicts a heightened experience of group cohesion. Additionally, higher physiological synchrony predicts enhanced group performance in a subsequent, different group task.
