It’s easy to miss the mirror forge at the University of Arizona. While sizable, the Richard F. Caris Mirror Laboratory sits in the shadow of the university’s much larger 56,000-seat football stadium. Even its most distinctive feature—an octagonal concrete prominence emblazoned with the school’s logo—looks like an architectural feature for the arena next door. But it’s that tower that houses some of the facility’s most critical equipment.

Inside the lab, a narrow, fluorescent-green staircase spirals up five floors to the tower’s entrance. I’m a few steps from the top when lab manager Stuart Weinberger asks, for the third time, whether I have removed everything from my pockets.

“Glasses, keys, pens. Anything that could fall and damage the mirror,” he says. Weinberger has agreed to escort me to the top of the tower and onto a catwalk some 80 feet above a mirror 27.5 feet in diameter. A mirror that has already taken nearly six years—and $20 million—to make. “Most people in the lab aren’t even allowed up here,” he says. That explains Weinberger’s nervousness about the contents of my pockets (which are really, truly empty), and why he has tethered my camera to my wrist with a short line of paracord.

The idea that science skills are innate and great discoveries are made only by “lone geniuses” is losing traction in STEM.

A growing body of research suggests that exposure to air pollution in the earliest stages of life is associated with negative effects on cognitive abilities. A new study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by “la Caixa”, has provided new data: exposure to particulate matter with a diameter of less than 2.5 μm (PM2.5) during pregnancy and the first years of life is associated with a reduction in fundamental cognitive abilities, such as working memory and executive attention.

The study, carried out as part of the BREATHE project, has been published in Environmental Health Perspectives. The objective was to build on the knowledge generated by earlier studies carried out by the same team, which found lower levels of cognitive development in children attending schools with higher levels of traffic-related air pollution.

The study included 2,221 children between 7 and 10 years of age attending schools in the city of Barcelona. The children’s cognitive abilities were assessed using various computerized tests. Exposure to air pollution at home during pregnancy and throughout childhood was estimated with a mathematical model using real measurements.

Researchers analyze secondary school curricula from 15 countries, revealing common themes and a need for emphasizing process over facts.

From Academy Award-winning director Alex Gibney comes a documentary about the rise and fall of Theranos, the one-time multibillion-dollar healthcare company founded by Elizabeth Holmes. Premieres March 18 on HBO.

Before he could legally drive, high school student Adam Rebei was already submitting jobs on the Blue Waters supercomputer at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign (NCSA) to run complex simulations of black holes.

“My first time using Blue Waters, we did a tour first and got to see the computer, which is a very amazing thing because it’s a very powerful machine,” Rebei told the NCSA, “and I just remember thinking, ‘All of the GPUs!’ It’s an insane amount of GPUs, and I’ve never seen anything like it.”

To get there, Rebei first took an astronomy class that led him to his work with the NCSA. Once there, he teamed up with research scientist Eliu Huerta, who leads the group’s Gravity Group.

The Aldabra white-throated rail, a flightless bird that lives on its namesake atoll in the Indian Ocean, doesn’t look like anything special at first glance. But the small bird has big bragging rights, because it has effectively evolved into existence twice after first going extinct some 136,000 years ago.

According to a study published Wednesday in the Zoological Journal of the Linnean Society, the rail is an example of a rarely observed phenomenon called iterative evolution, in which the same ancestral lineage produces parallel offshoot species at different points in time. This means that near-identical species can pop up multiple times in different eras and locations, even if past iterations have gone extinct.

Fossils of the flightless bird were found both before and after Albadra was submerged by an “inundation event” that occurred around 136,000 years ago, said study authors Julian Hume, an avian paleontologist at Natural History Museum in London, and David Martill, a paleobiologist at the University of Portsmouth.

From the beginning of the year 2019, the sales of Boox eReaders slightly increase, and so do many other brands such as Kindle, Kobo and Sony. All of them suffered a rapid drop in sales in the previous year but now they are getting back. This may cause by the event that France prohibits students from using smartphones and tablets in schools.

Under the legislation passed in 2018, the French students as old as 15 were not allowed to bring their smartphones as well as tablets to schools from September. The law was originally noted in President Emmanuel Macron’s election campaign. Now, one semester has gone, actually what do folks think to this policy? Earlier than that, France endorsed a blanket smartphone ban for drivers, even those who park at the side of the road, so the further action to school is not that surprising. It seems that the French government is getting realized that the control of electronics use is significant to beat back the encroachment of digital technology in everyday life.
