Acoustic propulsion of nanomachines depends on their orientation
Microscopically tiny nanomachines which move like submarines with their own propulsion—for example in the human body, where they transport active agents and release them at a target: What sounds like science fiction has, over the past 20 years, bec.....»»
Auto industry still heavily depends on Chinese parts. This Senate report shows why
This week's Senate Finance Committee report finding BMW imported thousands of vehicles with parts from a banned Chinese supplier underscores just how dependent on China the entire supply chain remains......»»
A spider silk sound system: Webs match acoustic particle velocity for long-distance sound detection
The best microphone in the world might have an unexpected source: spider silk. Spiders weave webs to trap their insect snacks, but the sticky strands also help spiders hear......»»
Researchers uncover how jelly sea creatures might shape modern robotics
Scientists at the University of Oregon have discovered that colonies of gelatinous sea animals swim through the ocean in giant corkscrew shapes using coordinated jet propulsion, an unusual kind of locomotion that could inspire new designs for efficie.....»»
Reducing distrust in social media is not straightforward, computer scientists warn
Are anti-misinformation interventions on social media working as intended? It depends, according to a new study led by William & Mary researchers and published in the Proceedings of the CHI Conference on Human Factors in Computing Systems (CHI '24)......»»
Model suggests subluminal warp drives may be possible
A team of physicists from the University of Alabama in Huntsville and the Advanced Propulsion Laboratory at Applied Physics, in New York, has developed a model that shows it might be possible to create a subluminal warp drive......»»
Here’s How Long the macOS Sonoma 14.5 Update Takes
The macOS Sonoma 14.5 update could take a long time to download and install on your Mac. The amount of time depends on your Mac model and the version of macOS it’s currently running. macOS Sonoma 14.5 is available to download right now if you own a.....»»
Here’s How Long the macOS Ventura 13.6.7 Update Takes
Apple’s macOS Ventura 13.6.7 update could take a long time to download and install on your Mac. It depends on your Mac model and the version of macOS it’s currently running. Apple’s released a new version of macOS Ventura and macOS.....»»
New surface acoustic wave techniques could lead to surfing a quantum internet
Researchers at the University of Rochester have used surface acoustic waves to overcome a significant obstacle in the quest to realize a quantum internet......»»
Research presents 2D dipole orientation method for mapping cells
Due to the high transparency of cells, it is very difficult to observe the organelles within them. Biologists can label specific organelles for observation through fluorescence staining. This is somewhat analogous to being in an environment without l.....»»
White Sands propulsion team tests 3D-printed Orion engine component
When the Orion spacecraft carries the first Artemis crews to the moon and back, it will rely on the European Service Module contributed by ESA (European Space Agency) to make the journey. The service module provides electrical power generation, propu.....»»
Artificial intelligence enhances monitoring of threatened marbled murrelet
Artificial intelligence analysis of data gathered by acoustic recording devices is a promising new tool for monitoring the marbled murrelet and other secretive, hard-to-study species, research by Oregon State University and the U.S. Forest Service ha.....»»
Extraordinary Vietnam fraud case exposes the inherent vulnerabilities of banks
The financial crisis of 2008 showed just how much the world depends on banks being well run. Since then, regulators have been given new powers to keep some of the biggest institutions on a much shorter leash to stamp out risk, greed and corruption......»»
Freeze casting—a guide to creating hierarchically structured materials
Freeze casting is an elegant, cost-effective manufacturing technique to produce highly porous materials with custom-designed hierarchical architectures, well-defined pore orientation, and multifunctional surface structures. Freeze-cast materials are.....»»
Pushing the limits of sub-kilowatt electric propulsion technology for space mission concepts
NASA has developed an advanced propulsion technology to facilitate future planetary exploration missions using small spacecraft. Not only will this technology enable new types of planetary science missions, one of NASA's commercial partners is alread.....»»
Multi-drug resistant bacteria found on International Space Station mutate to become functionally distinct
Principal Investigator Dr. Kasthuri Venkateswaran of NASA's Jet Propulsion Laboratory led a team that studied 13 strains of the bacterial species Enterobacter bugandensis that were isolated from the International Space Station (ISS). E. bugandensis i.....»»
NASA says it needs better ideas on how to return samples from Mars
The Jet Propulsion Laboratory is losing its grip on managing NASA's next flagship mission. Enlarge / NASA's existing plan for Mars Sample Return involves a large lander the size of a two-car garage, two helicopters, a two-stage b.....»»
Examining the blowtorch effect of satellite reentry through video
A reaction wheel—one of the heaviest parts of a space mission, its changing rotation used to shift a satellite's orientation—seen in a plasma wind tunnel belonging to the High Enthalpy Flow Diagnostics Group (HEFDiG) at the University of Stuttgar.....»»
Measuring the atmospheres of other worlds to see if there are enough nutrients for life
Life on Earth depends on six critical elements: carbon, hydrogen, nitrogen, oxygen, phosphorous, and sulfur. These elements are referred to as CHNOPS, and along with several trace micronutrients and liquid water, they're what life needs......»»
Scientists report that buffer and pH strongly affect the phase separation of SARS-CoV-2 N protein
In a new paper published in Molecular Biology of the Cell, the Allain lab (IBC) reported that the phase separation of the SARS-CoV-2 N protein strongly depends on the chosen buffer and pH. For example, the protonation of a single histidine side chain.....»»
NASA knows what knocked Voyager 1 offline, but it will take a while to fix
"Engineers are optimistic they can find a way for the FDS to operate normally." Enlarge / A Voyager space probe in a clean room at the Jet Propulsion Laboratory in 1977. (credit: Space Frontiers/Archive Photos/Getty Images).....»»
