Engineers describe how fluid suspensions exhibit different behaviors at different scales
Honey is already a thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs throughout the natural and constructed world: From mudflows to.....»»
Helping non-clinical staff identify problematic sexual behaviors among children
Identifying unusual and potentially harmful behaviors in children is vital to providing appropriate interventions, according to Penn State researchers. A Penn State research team partnered with the U.S. Department of Defense (DoD) to develop an easy-.....»»
New technique enhances imaging of fluid-filled rocks, finds connection to microearthquakes
An international team of scientists led by Dr. Xin Liu, Assistant Professor of the Department of Earth Sciences, The University of Hong Kong (HKU), along with seismologists from the U.S. and China, has recently introduced a new method called ambient.....»»
NASA"s interstellar mapping probe prepares for a 2025 launch
Engineers at NASA have completed an important milestone in developing the Interstellar Mapping and Acceleration Probe (IMAP) spacecraft. It's now moving from development and design to the assembly, testing, and integration phase, targeting a launch i.....»»
NASA engineers push limits of physics to focus light
A pair of precision-orbiting small satellites will attempt to capture the first views ever of small-scale features near the surface of the sun that scientists believe drive the heating and acceleration of solar wind......»»
Unlocking the secrets of oobleck—strange stuff that’s both liquid and solid

New enzyme allows CRISPR technologies to accurately target almost all human genes
A team of engineers at Duke University have developed a method to broaden the reach of CRISPR technologies. While the original CRISPR system could only target 12.5% of the human genome, the new method expands access to nearly every gene to potentiall.....»»
Exploring the impact of generative AI in the 2024 presidential election
2024 is a presidential election year in the US. 2016 and 2020 both saw impressive increases in attempts to influence voters through crafty propaganda and social media campaigns run by bots and expert social engineers, along with attempts to influence.....»»
Q&A: Unveiling a new era of imaging—engineers lead breakthrough microscopy techniques
When microscopes struggle to pick up faint signals, it's like trying to spot subtle details in a painting or photograph without your glasses. For researchers, this makes it difficult to catch the small things happening in cells or other materials. In.....»»
Counteracting bone and muscle loss in microgravity
In microgravity, without the continuous load of Earth's gravity, the tissues that make up bones reshape themselves. Bone cells readjust their behaviors—the cells that build new bone slow down, while the cells that break down old or damaged bone tis.....»»
AI model directly compares properties of potential new drugs
Biomedical engineers at Duke University have developed an AI platform that autonomously compares molecules and learns from their variations to anticipate property differences critical to discovering new pharmaceuticals. The platform provides research.....»»
Engineers tackle hard-to-map class of materials
The properties that make materials like semiconductors so sought after result from the way their atoms are connected, and insight into these atomic configurations can help scientists design new materials or use existing materials in new, unforeseen w.....»»
Control over friction, from small to large scales
Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, even at large scales, is determined by the formin.....»»
A theoretical approach to ferroelectricity in hafnia-related materials
Hafnia ferroelectrics are based on their technical promise and remarkable behaviors, where the peculiarities stem from an active extrinsic mechanism that contributes to their properties from a growing number of new intrinsic features......»»
Unity lays off hundreds of Weta Digital engineers as it pivots back to games
More cuts likely as troubled engine maker seeks to "increase our focus on our core." Enlarge / Kaboom! (credit: Aurich Lawson | Getty Images) Game engine-maker Unity has announced plans to lay off 265 workers—or just u.....»»
Scientists propose new method to search for deviations from the Standard Model of physics
In the search for new particles and forces in nature, physicists are on the hunt for behaviors within atoms and molecules that are forbidden by the tried-and-true Standard Model of particle physics. Any deviations from this model could indicate what.....»»
Best smart scales for Apple Health [November 2023]
Whether you’re working out with Apple Watch or just trying to live healthier, smart scales that sync data to the iPhone can be a fun and useful way to track your progress. If you want to easily collect your weight and other measurement data in t.....»»
Google Drive users complain of missing files, months of data disappearing
Cloud storage service Google Drive is losing user files, and engineers warn users to avoid making changes or troubleshooting while the issue is investigated and resolved.Missing files on Google DriveCloud storage solutions like iCloud or Google Drive.....»»
Researchers describe the journey of thermal antibubbles in a hot bath
Bubbles are thin liquid shells surrounded by air. Although less well known, there are also antibubbles, which are the opposite of bubbles, i.e., a thin envelope of vapor surrounded by liquid. In a new study, we show that it is possible to create anti.....»»
NASA engineers testing successor to Ingenuity helicopter rotors
NASA is investigating the possibility of more helicopters for future Mars missions, and recently shared a peek at its testing of new Mars helicopter hardware......»»
Bioinspired self-assembled colloidal collectives of active matter systems
