Roses are among the most economically significant ornamental plants worldwide, with widespread applications in the cut flowers, garden, and cosmetics industries. Yet fewer than 10% of rose species have contributed to modern cultivated roses. Until recently, available technologies did not allow to fully sequence the Rosa subgenus.
Evidence-based management is increasingly used by organizations to aid in decision-making, but research in this area is limited. In a new study, researchers developed and validated a new measure—the Evidence-Based Management Source Utilization Scale (EBM-SUS)—that is tailored to management and that captures the extent to which decision makers draw on four sources of evidence.
As long as there's been an internet, there's been a way to hack it. Scientists have spent decades imagining a different kind of network, one where the laws of physics make eavesdropping physically impossible, not just technically difficult. They call that dream a quantum internet.
Soil biologist Eric Slessarev has some advice for conservationists, landscapers, and farmers with fallow fields: Go touch deep-rooted grass. Or better yet, go plant some. Slessarev, an assistant professor of ecology and evolutionary biology in Yale's Faculty of Arts and Sciences, is the first author of a new study in Earth's Future showing that deep-rooted grasses store significantly more carbon in their root biomass than shallow-rooted crops—without harming the existing organic material already in the ground.
Researchers from the University of Twente and Harvard University have developed a new way to generate ultraviolet (UV) light on a photonic chip at power levels high enough for real-world use. For the first time, the technique produces milliwatt-level UV light on a chip. It is an important step for quantum technology, optical atomic clocks and advanced measurement equipment. The research is published in the journal Nature Communications.
The universe has a hidden structure, and a University of Virginia professor is mapping it in 3D, using 46 million galaxies and quasars and 19 million stars. Satya Gontcho A Gontcho, an assistant professor in the Department of Astronomy, is part of a team using the Lawrence Berkeley National Laboratory-led, Arizona-based Dark Energy Spectroscopic Instrument to conduct one of the most extensive surveys of the cosmos ever. DESI has built the largest 3D map of the universe ever created by humanity to study dark energy, one of the biggest mysteries in physics.
Astronomers at the University of Hawaiʻi have precisely measured the age of a nearby sun-like star and its unusual companion, known as a brown dwarf, an object that falls between a planet and a star. The discovery offers new clues into how brown dwarfs grow and change over time.
If you were to ask democracy scholars what they consider the greatest threat to American democracy, you might assume it is voters who support undemocratic practices or policies. But the real answer may surprise you: These voters are not the main problem.
A research collaboration, including a team of students from the University of Michigan, has published a new report that dives into an understudied aspect on changing ice cover on the Great Lakes. Namely, how do residents, business leaders and other stakeholders in the region perceive these changes and their impacts on their lives?
A new technology has been proposed that could fundamentally solve the issue of smartphones overheating during high-spec gaming or extended video streaming. Researchers at KAIST have discovered the principle of processing signals using the minute vibrations of magnets (spin waves) instead of electrons. This method significantly reduces heat generation and power consumption while enabling instantaneous frequency switching within the several GHz range. This breakthrough is expected to pave the way for smart devices with less heat and longer battery life, as well as ultra-low-power, high-speed computing.
