Researchers from the McKelvey School of Engineering at Washington University in St. Louis have developed a machine learning algorithm that can create a continuous 3D model of cells from a partial set of 2D images that were taken using the same standard microscopy tools found in many labs today.

Their findings were published Sept. 16 in the journal Nature Machine Intelligence.

“We train the model on the set of digital images to obtain a continuous representation,” said Ulugbek Kamilov, assistant professor of electrical and systems engineering and of computer science and engineering. “Now, I can show it any way I want. I can zoom in smoothly and there is no pixelation.”

The key to this work was the use of a neural field network, a particular kind of machine learning system that...

Strong alternating magnetic fields can be used to generate a new type of spin wave that was previously just theoretically predicted. This was achieved for the first time by a team of physicists from Martin Luther University Halle-Wittenberg (MLU). They report on their work in the scientific journal Nature Communications and provide the first microscopic images of these spin waves.

The basic idea of spintronics is to use a special property of electrons – spin – for various electronic applications such as data and information technology. The Spin is the intrinsic angular momentum of electrons that produces a magnetic moment...

Lasers have become a major part of our day-to-day lives. From phones and tablets to self-driving cars and data communication—even the information you’re reading right now is likely being delivered to you via lasers.

The technology’s applications are so broad even the researchers who deal with lasers daily are continuously amazed.

Among them is University of Queensland Research Fellow Dr. Martin Plöschner from the School of Information Technology and Electrical Engineering (ITEE).

“I’ve been working with lasers for the past 15 years and yet I’m often surprised to find them in the most unexpected places,” Dr. Plöschner said.

“In many of their applications, lasers operate in part of the spectrum which is...

A thin device triggers one of quantum mechanics’ strangest and most useful phenomena. An ultrathin invention could make future computing, sensing and encryption technologies remarkably smaller and more powerful by helping scientists control a strange but useful phenomenon of quantum mechanics, according to new research recently published in the journal Science.

Scientists at Sandia National Laboratories and the Max Planck Institute for the...
