With dual lasers, researchers at the Berkeley Lab Laser Accelerator Center accelerated a high-quality beam of electrons to 10 billion electronvolts in just 30 centimeters. The experiment gives scientists a “frame-by-frame” look at how a petawatt laser interacts with a long plasma channel, knowledge that’s crucial for building future compact particle accelerators.
Two University of Michigan faculty members have been elected to the National Academy of Inventors, the highest professional distinction awarded solely to inventors.
Cigarette smoking from childhood into early adulthood is associated with an increased risk of premature cardiac injury, according to a study published today in JACC, the flagship journal of the American College of Cardiology. This early damage to the structure and function of the heart can also significantly increase the chance of future cardiovascular (CVD) mortality in mid-life.
Even matter ejected by black holes can run into objects in the dark. Using NASA’s Chandra X-ray Observatory, astronomers have found an unusual mark from a giant black hole’s powerful jet striking an unidentified object in its path.
In a surprising development in the field of robotics, researchers have discovered that small modifications to a robot’s body mass and ball size can significantly enhance its balancing abilities. Focusing on the BallBot—a robot designed to balance on a ball—the study reveals that these seemingly simple design changes can lead to dramatic improvements in performance. This innovative approach holds the potential to make robots more stable and reliable in everyday applications, bringing them closer to becoming indispensable partners in our daily lives.
A cutting-edge study has uncovered crucial new insights into the effects of equatorial plasma bubbles (EPBs) on aircraft navigation systems, shedding light on the hidden dangers posed by these atmospheric phenomena. These disturbances in the ionosphere can interfere with satellite signals, putting aviation safety at risk. The research focuses on developing a predictive model to evaluate how EPBs disrupt ground-based systems vital for guiding planes safely during landing.
Scientists have unveiled a groundbreaking method (CSAC) to harmonize satellite ocean color data across various satellites, which paved the way for the generation of reliable, global-scale, long-term, bio-optical properties of the upper ocean. Such “big data” is the base to assess the status and climate-related dynamics of the marine ecosystems. The CSAC (Cross-Satellite Atmospheric Correction) system ensures consistent remote sensing reflectance (Rrs) products across different satellite ocean color missions, a crucial step for expanding spatial coverage and extending the temporal reach via the fusion of various satellite ocean color measurements.
A critical study sheds light on the growing global burden of esophageal cancer, outlining its significant impact and the imperative to identify the driving factors behind its increasing prevalence. This research presents a detailed analysis of the disease's incidence, mortality, disability-adjusted life years (DALYs) rates, and attributable risk factors, providing essential insights for the development of strategic cancer control measures on a global scale.
NGC 1068 is a well-known, relatively nearby, bright galaxy with a supermassive black hole at its center. Despite its status as a popular target for astronomers, however, its accretion disk is obscured by thick clouds of dust and gas. A few light-years in diameter, the outer accretion disk is dotted by hundreds of distinct water maser sources that hinted for decades at deeper structures. Masers are distinct beacons of electromagnetic radiation that shine in microwave or radio wavelengths; in radio astronomy, water masers observed at a frequency of 22 GHz are particularly useful because they can shine through much of the dust and gas that obscures optical wavelengths. Led by astronomer Jack Gallimore of Bucknell University, an international team of astronomers and students set out to observe NGC 1068 with twin goals in mind: astrometric mapping of the galaxy’s radio continuum and measurements of polarization for its water masers. “NGC 1068 is a bit of a VIP among active galaxies,”
Street art takes many forms, and the vibrant murals on the Berlin Wall both before and after its fall are expressions of people’s opinions. But there was often secrecy around the processes for creating the paintings, which makes them hard to preserve. Now, researchers reporting in the Journal of the American Chemical Society have uncovered information about this historic site from paint chips by combining a handheld detector and artificial intelligence (AI) data analysis.
