In the world of tiny tech, handling droplets is a big deal. Imagine trying to move and split tiny drops of liquid with precision. That's what digital microfluidic devices do. They use something called electrowetting on dielectric (EWOD) to control droplets. But there's a problem. The way droplets sp
Lying down for a long time can mess with how blood flows in your brain. This is what scientists found out when they studied 36 healthy adults who spent 90 days in a head-down bed rest position. They used a special kind of MRI called pseudo-continuous arterial spin labeling (pCASL) to track changes i
Have you ever wondered what's below Earth? It's not just empty space. Our solar system is like a giant pancake, with planets orbiting the sun in a flat plane. But what's beyond that plane? Gravity plays a big role in defining up and down. On Earth, down is toward the ground, but that changes depend
In space, things don't work the same as they do on Earth. This is especially true for tiny creatures like viruses and bacteria. A recent study looked at how these microbes act in the International Space Station (ISS). The findings show that in space, viruses might take longer to infect bacteria. Thi
In the vast world of space-time theories, scientists are diving deep into something called energy conditions. These are like rules that energy in the universe must follow. In particular, they are looking at a special kind of theory known as generalized teleparallel gravity. This theory is not just
In the vast theater of the cosmos, scientists have long been fascinated by the idea of a brane-world universe. This concept suggests that our familiar 4-dimensional world is like a stage, embedded within a larger 5-dimensional space known as the bulk. To make sense of this complex scenario, research
Renewable energy sources like wind and solar are crucial for reducing carbon emissions. However, their unpredictable nature makes it tough to keep the power grid stable. This is where advanced energy storage systems come in. Among these, gravity energy storage systems (GESS) stand out. They are scal
The latest brainchild from NASA is set to revolutionize how scientists study our planet's gravity. The Quantum Gravity Gradiometer Pathfinder (QGGPf) is a compact, yet powerful device designed to measure gravitational forces with unprecedented accuracy. This isn't just about understanding gravity; i
A lot of folks who have knee replacement surgery struggle to get moving again. In Finland, doctors and physiotherapists give patients tips and exercises before and after the operation. But being active is a big problem for many. Pain and discomfort often hold them back from walking and doing daily t
Blue Origin set off to the skies a few days back from their Texas launch site for a 29th run. This trip wasn’t about tourists having a blast in space. It was all about research. In a twist, they spun the capsule enough time to simulate moon gravity. That meant spinning up to 11 times a minu
