Imaging individual flexible DNA 'building blocks' in 3-D
A team of researchers from Lawrence Berkeley National Lab (Berkeley Lab) and Ohio State University have generated 3-D images from 129 individual molecules of flexible DNA origami particles. Their work provides the first experimental verification of the theoretical model of DNA origami.

Berkeley Lab 'minimalist machine learning' algorithms analyze images from very little data
Berkeley Lab mathematicians have developed a new approach to machine learning aimed at experimental imaging data. Rather than relying on the tens or hundreds of thousands of images used by typical machine learning methods, this new approach 'learns' much more quickly and requires far fewer images.

In a first, tiny diamond anvils trigger chemical reactions by squeezing
Scientists have turned the smallest possible bits of diamond and other super-hard specks into 'molecular anvils' that squeeze and twist molecules until chemical bonds break and atoms exchange electrons. These are the first such chemical reactions triggered by mechanical pressure alone, and researchers say the method offers a new way to do chemistry at the molecular level that is greener, more efficient and much more precise.

Bringing a hidden superconducting state to light
Using high-intensity pulses of infrared light, scientists found evidence of superconductivity associated with charge 'stripes' in a material above the temperature at which it begins to transmit electricity without resistance--a finding that could help them design better high-temperature superconductors.

Pacific Northwest National Laboratory, OHSU join forces to advance precision
Pacific Northwest National Laboratory and OHSU announced today a joint collaboration to improve patient care by focusing research on highly complex sets of biomedical data, and the tools to interpret them. The OHSU-PNNL Precision Medicine Innovation Co-Laboratory, called PMedIC, will provide a comprehensive ecosystem for scientists to utilize integrated 'omics, data science and imaging technologies in their research in order to advance precision medicine - an approach to disease treatment that takes into account individual variability in genes, environment and lifestyle for each person.

New turbulent transport modeling shows multiscale fluctuations in heated plasma
Researchers at the DIII-D National Fusion Facility used a 'reduced physics' fluid model of plasma turbulence to explain unexpected properties of the density profile inside a tokamak experiment. Modeling plasma's turbulent behavior could help scientists optimize the tokamak performance in future fusion reactors like ITER. They discuss their findings in this week's Physics of Plasmas.

Neutron study of glaucoma drugs offers clues about enzyme targets for aggressive cancers
A team of researchers from ORNL's Energy and Transportation Science Division is using neutron imaging to study particulate filters that collect harmful emissions in vehicles. A better understanding of how heat treatments and oxidation methods can remove layers of soot and ash from these filters could lead to improved fuel-efficiency.

Captured electrons excite nuclei to higher energy states
For the first time, scientists demonstrated a long-theorized nuclear effect called nuclear excitation by electron capture. This advance tests theoretical models that describe how nuclear and atomic realms interact and may also provide new insights into how star elements are created.

Solving the dark energy mystery: A new assignment for a 45-year-old telescope
Today, the dome closes on the previous science chapters of the 4-meter Mayall Telescope in Arizona so that it can prepare for its new role in creating the largest 3-D map of the universe. This map could help to solve the mystery of dark energy, which is driving the accelerating expansion of the universe.

New chapter begins for Kitt Peak telescope
A new chapter opens today in the history of the 4-m Mayall telescope, the largest aperture telescope at NSF's Kitt Peak National Observatory (KPNO). Having completed its first 45-year-long assignment, the telescope is now poised to embark on a new mission: creating the largest 3-dimensional map of the cosmos to date. The map will help astronomers chart out the role of dark energy in the expansion history of the Universe.
