What's behind the eclipse's red dotsYesterday's total eclipse stunned skywatchers. "It makes your heart want to skip a beat, and you cannot really describe it to someone who hasn't experienced it in person," retired educator Lynnice Carter told Nature. Some people could spot impressive solar prominences as reddish dots around the edges of the moon's shadow. Prominences are enormous loops of plasma, many times bigger than Earth, that can last several months. They often appear red because they contain hydrogen glowing at extremely high temperatures.

| We'd love to see your best photos of the eclipse or related views from the day. Please upload them here. 📸 Our favourite images will be featured in this Briefing and we'll send our top snapper a money-can't-buy Nature tote bag and pin badge. Thank you to everyone who's already shared their images with us! Connie Friedman's view from a canoe on Lake Erie, Beth Peshkin's portrait of Carly the dog putting safety first and Les Jones's image of totality in Kingston, Canada, are among our favourites so far. | |||||
Blackfoot people's ancient ice age lineageModern Blackfoot people are closely related to the first humans that populated the Americas after the last ice age. DNA analysis of six modern and seven historic individuals shows that they belong to a previously undescribed genetic lineage that extends back to more than 18,000 years ago. The data add to evidence from Blackfoot oral traditions and archaeological findings, and could support the claims that these people have to ancestral lands.

Cuts could leave Brazil's labs darkSome scientists in Brazil say their labs won't have enough money to cover basic expenses such as electricity and water unless more funding is found. Institutions in the Amazon argue that they are the hardest hit because their federal support is already disproportionately low. President Luiz Inácio Lula da Silva's administration is fighting to reverse some of the budget cuts imposed by the country's legislators. Nature | 5 min read | |||||

How changing environments mold lifeThe very different ways that communities of desert ants and forest ants find their food demonstrates how our unpredictably messy world drives the evolution of social behaviours, argues biologist Deborah Gordon in The Ecology of Collective Behavior. The idea is not as contentious as Gordon makes out, writes reviewer and ecologist Seirian Sumner. But it still highlights a crucial point: "The interactions between organisms and their environments have become increasingly overlooked because fewer researchers are studying animals in their natural environments."

'I felt a lot of pressure to prove myself'"I tried to compensate for my disability by working longer hours," recalls biochemist Kamini Govender, who has a condition that severely affects her peripheral vision. She developed coping strategies, but ended up working at an unsustainable pace. "Over time, I have learnt to practise better self-care by knowing when to stop." More needs to be done to include people with disabilities, Govender says. "In the sciences, few of these people make it to the level that I have, because of all the hurdles they come across. It's easier to quit and give up." Nature | 6 min read | |||||
What students think about AI in educationSeveral student-led groups and conferences are working to ensure that they have a part in determining AI's role in education. Students recognize that the technology can be a double-edged sword, but caution against knee-jerk blanket bans. "In talking to lecturers, I noticed that there's a gap between what educators think students do with ChatGPT and what students actually do," says computer science student Johnny Chang.

| Dario Sandrini's environment and education foundation, KIDO, has run around 30 projects on the small Caribbean island of Carriacou — from protecting sea turtles to replanting mangroves. He's now working on restoring areas that have been logged, in some cases, illegally. "With another ten years of care, we will see the forest resurge," he says.

Quote of the day"The Dunning-Kruger effect visits all of us sooner or later in our pockets of incompetence."Don't judge other people on the basis of the cognitive bias he co-discovered, says social psychologist David Dunning. Use the fact that people with limited competence in an area overestimate their expertise to reflect on yourself, instead. (Scientific American podcast | 33 min listen or 11 min read) | |||||
