Purdue University researchers built this bizarre crawling robot baby to study how real infants kick up dirt and bacteria from carpet that they then inhale. Engineer Brandon Boor and his colleagues ran the robot over carpet samples removed from people's homes and then analyzed the particulates that were stirred up. Turns out that the particle concentration is as much as 20 times greater than higher up in the room where we adults breathe. That isn't necessarily bad though, Boor says.
"Many studies have shown that inhalation exposure to microbes and allergen-carrying particles in that portion of life plays a significant role in both the development of, and protection from, asthma and allergic diseases," says Boor, an assistant professor of civil engineering and environmental and ecological engineering. "There are studies that have shown that being exposed to a high diversity and concentration of biological materials may reduce the prevalence of asthma and allergies later in life."
Nepal is banning disposable plastic soda bottles and other single-use plastic items in Khumbu, the region where Mount Everest is located. In May, volunteers collected more than six thousand pounds of trash from the mountain. This new ban is meant to reduce the amount of garbage left by tourists and climbers on Everest and in […]
The Right to Repair movement has introduced dozens of state-level laws that would force companies to support independent repairs by making manuals, parts and diagnostic codes available, and by ending the illegal practice of voiding warranties for customers who use independent repair services, but these bills keep getting killed by overwhelming shows of lobbying force […]
Mary Annaise Heglar of the Natural Resources Defense Council is tired of her friends confessing their environmental sins to her, like using disposable containers; as she points out, climate change is a systemic problem, not an individual one, and the Ayn-Rand-ish framing of all problems as having individual causes with individual solutions is sheer victim […]
There’s no shortage of stories about the benefits of cannabidiol, that benign (and non-psychoactive) cousin of THC. Some have been using it for years to deal with pain, stress, and sleeplessness. And the more people use it, the more discussion there is about how to use it. While there’s no shortage of quality edibles on […]
Are we done with capsule coffee makers yet? Sure, they’re easy. But they are not so easy on the environment, and it’s debatable whether they actually make a better cup. Luckily, there’s never been a better time to switch back to the good old reliable drip method – especially when drip coffeemakers have quietly been […]
If there’s one thing that stayed consistent through the last decade or so of tech industry turmoil, it’s the love affair between techies and Linux. There’s just a ton you can do with the OS, and its open-source format means you can customize your rig from the ground up. Apparently not content with that level […]
