La production de cacao est fortement concentrée dans quelques pays d'Afrique occidentale, dont la Côte d'Ivoire et le Ghana.
L’engouement des consommateurs pour le chocolat est hélas lié à déforestation illégale d’écosystèmes très protégés. Mais peu à peu, des progrès sont accomplis pour favoriser le commerce éthique.
Seabed sediments in Bermuda mangroves consumed nitrous oxide from the seawater. Restoring coastal ecosystems might help curb climate change.
Nitrous oxide is a potent greenhouse gas, 300 times more powerful than carbon dioxide. Global emissions of N2O are on the rise as a result of human activities — and their impact on ocean ecosystems.

Côte d'Ivoire and Ghana produce almost two-thirds of the world’s cocoa, and face high rates of deforestation. But the cocoa industry could make changes to become more sustainable.
The limiting factor in cancer radiotherapy is that doses high enough to try to cure tumours also damage surrounding normal tissues.
Higher doses of radiotherapy for cancer treatment destroy more healthy tissue as well as more tumour cells. Gold nanoparticles sensitize tumours to radiation, making treatment more effective.

Banning research ties with China, as Alberta just did, should be vetoed not only by the academic community but also the general public for its recklessness in fanning the flames of anti-Asian racism.
While there have been calls to increase support for women, particularly mothers, it would seem that no one is asking fathers to step up.
Despite the disproportionate burden mothers have faced during lockdown, encouraging parents to share child care and housework more equally is almost never suggested as part of the solution.
It’s when we use our online networks as pipes, not prisms, that small matters and seems to be valuable.
If you want to give and get help from your online network, new research suggests keep your "friend" count low.
Intake workers assist visitors at an immigrant and refugee vaccine clinic set up by Global Medic in Toronto in April. Research suggests racialized immigrant women earn less money than other groups, regardless of how much training, education or networking they do.

This year’s 93rd Academy Awards are celebrating Asian women from Chloé Zhao (Nomadland) to Christina Oh (Minari) and Yuh-jung Youn (Minari).
Relying on familiar stereotypes and images can make us miss this critical opportunity to reshape the ways in which Asian women are viewed as individuals and artists.
It is easy to think that handwashing is accessible to all today, but COVID-19 calls attention to communities both within Canada and around the globe where clean water is not a given.
Why is socio-economic inequality so threatening to complex societies and how can archaeology inform public policies for mitigating it?

Fifteen Asian academics discuss the roots of anti-Asian racism and limits of multiculturalism in Canada while charting a path forward.
Everyday environments and activities, from transportation to screen time to eating, are tailored nearly exclusively to prolonged sitting.
Too much time sitting is linked to health risks, and also to lower quality of life. But in some contexts, such as reading, playing an instrument or socializing, sitting had positive associations.
Dostoyevsky’s story ‘The Double’ explores the uncanny theme of a replica of oneself, but today’s literary foes are often amorphous ones like environmental degradation.
Beyond the ‘literature of madness,’ the narratives about mental and physical health published today explore the interdependence of bodies and their environments.

Belugas use sound to communicate, navigate the dark marine environment and find food. But climate change is opening up Arctic waters to more sound, and could affect the health and survival of belugas.

Indigenous activists have long called on teams to change names and mascots that perpetuate negative stereotypes and fail to respect painful histories.
NFL teams like the Washington Redskins changing names that demean First Nations and Native Americans is a long overdue step in the right direction.
