Researchers convert 2-D images into 3-D using deep learning

A UCLA research team has devised a technique that extends the capabilities of fluorescence microscopy, which allows scientists to precisely label parts of living cells and tissue with dyes that glow under special lighting. The researchers use artificial intelligence to turn two-dimensional images into stacks of virtual three-dimensional slices showing activity inside organisms.

Machine learning enhances light-beam performance at the advanced light source

Synchrotron light sources are powerful facilities that produce light in a variety of "colors," or wavelengths—from the infrared to X-rays—by accelerating electrons to emit light in controlled beams.

Obtaining order in the "frustrated" landscape of disordered magnetism

Identifying a material's magnetic structure is a key to unlocking new features and higher performance in electronic devices. However, solving increasingly complex magnetic structures requires increasingly sophisticated approaches.

Researchers measure wake of supersonic projectiles

Imaging technology has vastly improved over the past 30 years. It's been about that long since the flow coming off of the base of projectiles, such as ballistic missiles, has been measured. Researchers in the Department of Aerospace Engineering at the University of Illinois at Urbana-Champaign used a modern measurement technique called stereoscopic particle image velocimetry to take high-resolution measurements of the complicated flow field downstream of a blunt-based cylinder moving at supersonic speeds, which is representative of a projectile or an unpowered rocket.

Researchers model avalanches in two dimensions

There's a structural avalanche waiting inside that box of Rice Krispies on the supermarket shelf. Cornell researchers are now closer to understanding how those structures behave—and in some cases, behave unusually.

New measurement yields smaller proton radius

Using the first new method in half a century for measuring the size of the proton via electron scattering, scientists have produced a new value for the proton's radius in a new experiment.

Using the first new method in half a century for measuring the size of the proton via electron scattering, the PRad collaboration has produced a new value for the proton's radius in an experiment conducted at the Department of Energy's Thomas Jefferson National Accelerator Facility.

CERN appoints Gianotti, first female chief, to second term

The European research center that runs the world's largest atom smasher says it has reappointed Italian physicist Fabiola Gianotti, its first female director, for a second five-year term.

Simulations show how massive black holes could be formed by mergers

A team of researchers affiliated with several institutions in the U.S. along with one in India and one in Hungary has created simulations that could explain how larger than expected black holes could form near supermassive black holes at the center of galaxies. In their paper published in the journal Physical Review Letters, the group describes how they made their simulations and what they showed.
