Researchers generate, for the first time, a vortex beam of atoms and molecules

Vortices may conjure a mental image of whirlpools and tornadoes—spinning bodies of water and air—but they can also exist on much smaller scales. In a new study published in Science, researchers from the Weizmann Institute of Science, together with collaborators from the Technion-Israel Institute of Technology and Tel Aviv University, have created, for the first time, vortices made of a single...

Shrinking qubits for quantum computing with atom-thin materials

For quantum computers to surpass their classical counterparts in speed and capacity, their qubits—which are superconducting circuits that can exist in an infinite combination of binary states—need to be on the same wavelength. Achieving this, however, has come at the cost of size. Whereas the transistors used in classical computers have been shrunk down to nanometer scales, superconducting...

Flu virus shells could improve delivery of mRNA into cells

Nanoengineers at the University of California San Diego have developed a new and potentially more effective way to deliver messenger RNA (mRNA) into cells. Their approach involves packing mRNA inside nanoparticles that mimic the flu virus—a naturally efficient vehicle for delivering genetic material such as RNA inside cells.

Extroverted? You may have better financial outcomes

You might think the way you approach money is based on financial advice or past experiences, but new research from the University of Georgia shows that your personality may have a big impact on financial decision making and risk taking.

Bringing 400-million-year-old fossilized armored worms to 'virtual' life

An international team of scientists from the United States and Australia, led by Sarah Jacquet at the University of Missouri, has documented the discovery of two new species of fossilized armored worms in Australia—Lepidocoleus caliburnus and Lepidocoleus shurikenus—dating from about 400 million years ago. Then, using the micro-CT imaging capabilities of the MU X-ray Microanalysis Core...

Build your own office podcast studio

Converting newly emptied office spaces into podcast studios poses noise challenges not previously realized before hybrid offices began. Experts recommend considering location, nearby noise sources, and ways to absorb sound to make a studio effective.

Humidity changes in dead fern fronds drives unique timing of spore dispersal in a widespread fern species

The sensitive fern—named due to its sensitivity to drought and frost—is a widespread species found throughout eastern North America and eastern Asia. It is a dimorphic plant because it has two distinct types of leaves—one for photosynthesis and one for reproduction. While most fern species in temperate regions produce and disperse their spores in the summer, the sensitive fern has an...

Understanding how to build resilient fisheries

A new decision-making framework designed by an international team of fisheries researchers can help fisheries bolster their ability to adapt to a warming world. The tool, said marine ecologist Jacob Eurich at UC Santa Barbara's National Center for Ecological Analysis & Synthesis (NCEAS), is meant to take a lot of the guesswork out of finding resilience in a time of climate change.

Physicists create time crystals with quantum computers

There is a huge global effort to engineer a computer capable of harnessing the power of quantum physics to carry out computations of unprecedented complexity. While formidable technological obstacles still stand in the way of creating such a quantum computer, today's early prototypes are still capable of remarkable feats.
