Gene for lung and diaphragm development in mice and humans
To breathe normally, people need more than just healthy lungs. A diaphragm—the large muscle that creates a vacuum to draw air into their lungs—is also crucial. Birth defects in the diaphragm, such as congenital diaphragmatic hernia (which are about as common as cystic fibrosis), are often fatal. “A lot of people haven’t heard of this [disorder] because so many of the kids die early,” said Kate Ackerman, Harvard Medical School researcher and lead author of the study in PLoS Genetics.
To explore the genetic roots of these birth defects—hitherto a mystery—Ackerman and her colleagues screened mice with induced genetic mutations. The researchers discovered that a mutation in the mouse Fog2 gene can cause small lungs and abnormal diaphragm development. Could the same gene be involved in human diaphragmatic defects? After studying children with similar problems, the authors did indeed identify a child with a serious Fog2 gene mutation who died on the first day of life with severe breathing difficulties, small lungs, and an abnormal diaphragm.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
