In a second-floor windowless room on the rundown Carl Hayden Community High School campus, four students huddle around an odd, 3-foot-tall frame constructed of PVC pipe. At the top sits a black, waterproof briefcase containing a nest of hacked processors, minuscule fans, and LEDs. It's a cheap but astoundingly functional underwater robot capable of recording sonar pings and retrieving objects 50 feet below the surface. The four teenagers who built it are all undocumented Mexican immigrants who came to this country through tunnels or hidden in the backseats of cars. But over three days last summer, these kids from the desert proved they are among the smartest young underwater engineers in the country. Read on to hear their story.
Superheroes are lending a helping hand to a hospital in Brazil that takes care of kids fighting cancer. Batman, Superman, the Green Lantern and Wonder Woman are just some of the friendly faces taking on chemotherapy treatment alongside kids at the A.C. Camargo Cancer Center in Sao Paulo, Brazil.
In our science in past centuries, we have learned a lot about the law of gravity and similar laws of physics, but we have not learned very much about the laws of sustainability. In this article, Fritjof Capra (cofounder of the Center for Ecoliteracy in Berkeley, California) discusses what he calls the natural laws of sustainability which he developed from studying natural ecosystems and the ways in which they organize themselves. By uncovering the natural sustainability laws of interdependence, recycling, partnership, flexibility, and diversity, Capra sheds light on how we can create sustainable communities which can satisfy our needs without diminishing the chances of future generations.
A children's charity in Norway set up an experiment to see what people near a bus stop would do if there were a boy sitting alone on the bench shivering. The heart-warming video of men taking off their coats for the boy -- and women giving their gloves, scarves and hoodies -- was posted on YouTube today along with a plea to help other children, especially the children of Syria.
Whether lingering too long over the menu at a restaurant, or abrupt U-turns by politicians, flip-flopping does not have a good reputation. By contrast, quick, decisive responses are associated with competency. Steve Fleming, a cognitive neuroscientist, wonders whether the allure of decisiveness might be leading us astray. Perhaps, when faced with a novel scenario, there is a benefit from being slow.
