Using a comprehensive global dataset including 27,297 measurements of wood density from 2,621 tree species worldwide, we test the hypothesis that the legacy of evolutionary history plays an important role in driving the variation of wood density among tree species.
Leptospirosis is an illness caused by a bacteria called leptospira that can be present in soil and stagnant water. Rodents and other wildlife carry the bacteria and spread it through their urine. Both humans and dogs can become sick with leptospirosis, while cats are considered disease-resistant. For both people and dogs, the result of infection can range from mild to deadly serious.
An interdisciplinary team of scientists from Jefferson Lab, Old Dominion University and the DOE’s Oak Ridge National Laboratory have developed a conceptual device for quantum computing that could rival – or even outperform – other systems being developed. The “core” of this computer would be based on a compact, spin-transparent storage ring, which can maintain the entangled states of ions as they travel along a figure-eight path.

Survey reveals nearly three-quarters of U.S. adults support using emerging technology to screen embryos during IVF for risk of developing certain health conditions or traits that arise from more than one gene. Only about one-third of respondents approved of using the technology to predict traits unrelated to disease. Nearly all expressed concerns about potential negative outcomes for individuals or society. Findings underscore need for public education about benefits, limitations, ethical hazards of polygenic risk scores for embryos.
Microtoroid resonators are one of the most sensitive biochemical sensors, capable of detecting single molecules. Light is most commonly coupled into these sensors using a fragile and vibration-sensitive tapered optical fiber, preventing translation to field-portable sensing. Scientists from the University of Arizona have achieved far-field coupling of light to ultra-high quality factor microtoroids using a single objective lens. This is the foundation of a fully on-chip multiplexed microtoroid sensing platform.
Understanding the solid target ultrafast phase transitions induced by a high-intensity ultra-short laser pulse is crucial to many applications as laser-induced ablation or laser-driven ion acceleration. Scientists from Germany and France have used a single-shot probing technique that reveals the transition dynamics of the target from cold solid to overdense plasma.
