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."
Antti Lipponen of the Finnish Meteorological Institute created this troubling but unsurprising chart of almost 140 years of temperature anomalies by country. The data used was from the NASA GISS, Land Ocean Temperature Index. You can probably guess what will happen.
In ten years, scientists hope to have mapped the entire ocean floor in high resolution. This week, the Nippon Foundation-GEBCO Seabed 2030 Project announced that they’ve completed 20 percent of the map. A full mapping to “modern standards” is useful for conservation and also to support scientific understanding of ocean systems, weather, tsunami wave propagation, […]
Twenty-five experts have issued a warning about the potentially cataclysmic consequences of the rapidly shrinking insect population, reports The Guardian. In a two-part article for Biological Conservation, the scientists wrote: “The current [insect] extinction crisis is deeply worrisome. Yet, what we know is only the tip of the iceberg.We know enough to act immediately. Solutions […]
If the last 50 years of education have taught us nothing else, it’s that it often requires different tactics to best reach different learners. To pick up a foreign language, some students take best to the old-school high school language lab method, using heavy repetition, verb conjugation and grammar emphasis to embed a new language. […]
For those who want a career in video games, there’s no reason to sit around and wait. EA and Rockstar Games probably aren’t going to seek you out and knock on your door with a job opportunity. But if you’re an indie developer with a good idea and some passion, you can create a really […]
Nobody is happy about the current state of our COVID-ravaged education system. With a new school year fast approaching, plans for teaching students still in flux, and political in-fighting driving more fear and confusion about whether or not to re-open campuses, teachers and parents are concerned. Meanwhile, most kids are just fine with spending less […]
