The STEM Crisis Is a Myth

Forget the dire predictions of a looming shortfall of scientists, technologists, engineers, and mathematicians

You must have seen the warning a thousand times: Too few young people study scientific or technical subjects, businesses can't find enough workers in those fields, and the country's competitive edge is threatened.

It pretty much doesn't matter what country you're talking about—the United States is facing this crisis, as is Japan, the United Kingdom, Australia, China, Brazil, South Africa, Singapore, India…the list goes on. In many of these countries, the predicted shortfall of STEM (short for science, technology, engineering, and mathematics) workers is supposed to number in the hundreds of thousands or even the millions. A 2012 report by President Obama's Council of Advisors on Science and Technology, for instance, stated that over the next decade, 1 million additional STEM graduates will be needed. In the U.K., the Royal Academy of Engineering reported last year that the nation will have to graduate 100 000 STEM majors every year until 2020 just to stay even with demand. Germany, meanwhile, is sa to have a shortage of about 210 000 workers in what's known there as the MINT disciplines—mathematics, computer science, natural sciences, and technology.

A Transistor for Sound Points Toward Whole New Electronics

“Topological” acoustic transistor suggests circuits with dissipationless flow of electricity or light

Model of a honeycomb lattice

Model of a honeycomb lattice that serves as the basis for a "transistor" of sound waves—whose design suggests new kinds of transistors of light and electricity, made from so-called topological materials. Electrons in a topological transistor, it is suspected, would flow without any resistance.

Hoffman Lab/Harvard SEAS

Potential future transistors that consume far less energy than current devices may rely on exotic materials called "topological insulators" in which electricity flows across only surfaces and edges, with virtually no dissipation of energy. In research that may help pave the way for such electronic topological transistors, scientists at Harvard have now invented and simulated the first acoustic topological transistors, which operate with sound waves instead of electrons.

Topology is the branch of mathematics that explores the nature of shapes independent of deformation. For instance, an object shaped like a doughnut can be deformed into the shape of a mug, so that the doughnut's hole becomes the hole in the cup's handle. However, the object couldn't lose the hole without changing into a fundamentally different shape.

Taking Cosmology to the Far Side of the Moon

New Chinese program plans to use satellites in lunar orbit to study faint signals from early universe

A team of Chinese researchers are planning to use the moon as a shield to detect otherwise hard-to-observe low frequencies of the electromagnetic spectrum and open up a new window on the universe. The Discovering the Sky at the Longest Wavelengths (DSL) mission aims to seek out faint, low-frequency signals from the early cosmos using an array of 10 satellites in lunar orbit. If it launches in 2025 as planned, it will offer one of the very first glimpses of the universe through a new lens.

Nine “sister” spacecraft will make observations of the sky while passing over the far side of the moon, using our 3,474-kilometer-diameter celestial neighbor to block out human-made and other electromagnetic interference. Data collected in this radio-pristine environment will, according to researchers, be gathered by a larger mother spacecraft and transmitted to Earth when the satellites are on the near side of the moon and in view of ground stations.

McMaster Engineering: Transforming Education and Fostering Research With Impact

By adding new faculty and developing innovative approaches to its curriculum, McMaster solidifies its world leading position in engineering

3 min read

The Faculty of Engineering at McMaster University in Hamilton, Ont., Canada is aiming to build on its ranking as one of the world's top engineering schools by expanding its recruitment of both tenure-track and teaching track positions across multiple departments. This broad initiative is expected to continue the growth of McMaster as a leading destination for innovative teaching and research.
