Wireless brain implant to make friends?

Using the tiny, battery-free brain implant device, the team were able to program and deprogram mice to socially interact with each other in real-time. When two or more mice had their devices switched on, they interacted much more than usual, and when the device was switched off, the opposite effect was nearly immediate. Read more

Why Tired Chinese Youth are Going Punk to Tackle Their Sleep Problems

A recent survey shows that in 2020, although people spent more time at home thanks to the Covid-19 pandemic, it took them an extra two or three hours to fall asleep, while the number of online searches for sleep problems increased 43%. In just six years, the national average sleep time dropped by two hours, from 8.8 hours in 2013 to 6.9 in 2019. And perhaps not surprisingly, those in their twenties and thirties sleep the latest — and least — among all age groups. Read more (RADII)

The Anthropocene Education Program in partnership with Royal Canadian Geographical Society (RCGS)

The Anthropocene Project is proud to bring a unique bilingual education program to teachers across Canada FOR FREE, in partnership with the Royal Canadian Geographical Society (RCGS).

The Anthropocene Education Program (AEP) includes incredible 360 VR films; educational short films, online interactive gigapixel photographsAR experiences, and a large-scale high-resolution Giant Floor Mural depicting one of Edward Burtynsky’s photographs with related film extensions (part of a travelling school kit), and brand new content focused on the theme of “Plastics in the Anthropocene”.  These assets augment specific teacher guides and lesson plans written by the qualified educators from Can Geo Education and linked to the Canadian National Learning Framework for grades 4-12 Geography, or primaire 4 to secondaire 5 in Quebec.

The program leverages the stunning audiovisual resources of The Anthropocene Project, and the proven expertise and distribution networks of The Royal Canadian Geographical Society to create a powerful and change-provoking experiential understanding of human impact on the planet for students in classrooms from coast to coast, ages 9 – 18.  The program will reach more than 23,000 classroom teachers from across the country through the RCGS’s educational arm, Canadian Geographic (Can Geo) Education.

Juvenile ravens experience emotional contagion when watching another raven play. (emerging traits)

Perceiving, evaluating and reacting towards conspecifics’ emotional states are important challenges of social group living. Emotional contagion describes an alignment of emotional states between individuals and is widely believed to be based on behavioral synchronization, i.e., behavioral contagion. As basic empathy-like processes, the occurrence of both forms of contagion seems to underlie early ontogenetic trajectories in humans and non-human species. In the present study, we assessed play as a context for studying the development of emotional contagion and its interlink with behavioral contagion in ten juvenile common ravens. Ravens are exceptional players that engage in all three forms of play: object, locomotion and social play. To assess potential ontogenetic patterns of both behavioral and emotional contagion, we tested juvenile ravens at two different periods of early development, at three- and six-month post-hatching. We elicited object play in one or several ravens (demonstrators) in a standardized experimental environment, using a playground setup. At both test ages, we found evidence for emotional contagion as observer ravens showed an increase of locomotion and social play after we provided the demonstrator(s) with the playground setup, but no significant changes in the amount of object play. Hence, observers did not copy motor patterns from demonstrator(s) but engaged in other forms of play. Our findings speak for a transfer of a general mood state in the context of play in ravens as young as 3 months and against behavioral mimicry as a precondition for emotional contagion. Read more
