NASA tests new spacecraft propellant gauge on lunar lander
It's easy to measure fuel in tanks on Earth, where gravity pulls the liquid to the bottom. But in space, the game changes. Quantifying fuel that's floating around inside a spacecraft's tank isn't so simple......»»
Multi-dimensional multiplexing optical secret-sharing framework with cascaded liquid crystal holograms
Information security has become particularly crucial under the background of the big data era. Optical secret-sharing schemes encrypt information and physically divide it into different shares. Information can only be decrypted by cascading a suffici.....»»
Quick and easy preparation of small-sized metal nanoparticles by microchip laser
Pulsed laser ablation in liquid (PLAL) is a reliable and versatile technique for producing metal nanoparticles (NPs) in solution. Its advantages, including the absence of reducing agents, operational simplicity, high purity without purification steps.....»»
Bioinspired hydrogel pattern enhances atmospheric water harvesting via directional droplet steering
The water in the air originates from both natural and forced evaporation, with condensation being the final and crucial step in water harvesting. Condensation involves nucleation, growth, and shedding of water droplets, which are then collected......»»
Geometric phase-encoded liquid crystal optical sensing
Sensing technology, integral to environmental monitoring, data acquisition, and precision data processing, is evolving rapidly. Researchers are at the forefront of developing swift, accessible, and cost-effective sensors. Among these innovations, cho.....»»
What coffee with cream can teach us about quantum physics
Add a dash of creamer to your morning coffee, and clouds of white liquid will swirl around your cup. But give it a few seconds, and those swirls will disappear, leaving you with an ordinary mug of brown liquid......»»
Liquid lithium on the walls of a fusion device helps the plasma within maintain a hot edge
Emerging research suggests it may be easier to use fusion as a power source if liquid lithium is applied to the internal walls of the device housing the fusion plasma......»»
Making a superconductor liquid–solid out of the vacuum with hundred-exatesla-strong magnetic fields
The discovery of superconductivity more than a century ago has significantly changed our world......»»
Stem cell study throws our understanding of gene regulation for a loop
The blueprint for human life lies within the DNA in the nucleus of each of our cells. In human cells, around six and a half feet of this genetic material must be condensed to fit inside the nucleus. DNA condensation is not random. To function properl.....»»
Scientists open door to achieving high-precision "slippery structural hydrogel"
Hydrogels inevitably undergo dehydration, structural collapse, and shrinkage deformation due to the uninterrupted evaporation in the atmosphere, thereby losing their flexibility, slipperyness, and manufacturing precision......»»
Elon Musk’s recent all-hands meeting at SpaceX was full of interesting news

Tahoe avalanche: What causes seemingly safe snow slopes to collapse? A physicist and avid skier explains
An avalanche swept up skiers at Lake Tahoe's largest ski resort on Jan. 10, 2024, as a 150-foot-wide sheet of snow slid down a mountain slope into a pile 10 feet deep. One person died in the avalanche, and three others were rescued, according to the.....»»
New study suggests some forms of life could exist in Venus"s sulfuric acid clouds
A team of chemists and planetary scientists from Worcester Polytechnic Institute, Nanoplanet Consulting and MIT has found evidence that a form of life that uses sulfuric acid as a liquid medium could exist in some of the clouds covering Venus. The te.....»»
Unraveling the complexity of melon-pumpkin graft collapse
Grafting melon (Cucumis melon L.) onto pumpkin (Cucurbita maxima Duch. × Cucurbita moschata Duch.) rootstock is a method of improving yield but is challenged by the scion-rootstock incompatibility leading to plant collapse attributed to various phys.....»»
Stripes in a flowing liquid crystal suggest a route to "chiral" fluids
Hold your hands out in front of you, and no matter how you rotate them, it's impossible to superimpose one over the other. Our hands are a perfect example of chirality—a geometric configuration by which an object cannot be superimposed onto its mir.....»»
Roborock shows off highly automated robot vacuums at CES 2024
Revealed during CES 2024, the Roborock S8 MaxV Ultra can connect to your drain and water lines to automatically refill and empty its water tanks......»»
East Coast land continues to collapse at a worrying rate
It's steadily sinking or subsiding, which is destabilizing levees, roads, and airports. Enlarge / Lower Manhattan and One World Trade Center in New York City are reflected on a monument as the sun rises on December 22, 2023, as s.....»»
Study warns of widespread population collapse of African raptors
An international team of researchers has found that Africa's birds of prey are facing an extinction crisis. The study, co-led by researchers from the School of Biology at the University of St Andrews and The Peregrine Fund, warns of declines among ne.....»»
Crypto hedge fund CEO may not exist; probe finds no record of identity
