A colonoscopy is the best way to screen for colorectal cancer. Everyone at average risk for the disease should start getting them at age 45.
If you’re scheduled for your first colonoscopy, you may be wondering what to expect and how much time it will take. While the procedure itself could take as little as 20 minutes, once you factor in the prep and recovery time, the experience does take longer.
We spoke with gastroenterologist Mazen Alasadi, M.D., to learn more.
Brain waves act as carriers of information. A recently proposed “Cytoelectric Coupling” hypothesis suggests that these wavering electric fields contribute to the optimization of the brain network’s efficiency and robustness. They do this by influencing the physical configuration of the brain’s molecular framework.
In order to carry out its multifaceted functions, which include thought, the brain operates on various levels. Information like objectives or visuals is depicted through synchronized electrical activity among neuronal networks. Simultaneously, a combination of proteins and other biochemicals within and surrounding each neuron physically execute the mechanics required for participation in these networks.
A new paper by researchers at MIT, City University of London, and Johns Hopkins University posits that the electrical fields of the network influence the physical configuration of neurons’ sub-cellular components to optimize network stability and efficiency, a hypothesis the authors call “Cytoelectric Coupling.”

Four volunteers are about to enter a simulated Mars habitat where they’ll spend the next 378 days as part of ongoing preparations for the first crewed mission to the faraway planet.
The specially designed, enclosed habitat at NASA’s Johnson Space Center in Houston, Texas, will host Alyssa Shannon, Ross Brockwell, Kelly Haston, and Nathan Jones from Sunday, June 25. The team’s experience spans science, engineering, and health, and each member will use their specific skills during their stay.
The mission will be the first of three one-year Mars surface simulations, called CHAPEA (Crew Health and Performance Exploration Analog).
Debris field found — the crew perished in a catastrophic implosion. What are the lessons to be learned from this? How does this apply to future space, stratospheric, and oceanic tourism?

The above considerations have to be carefully factored in while selecting the approach to model different subsystems and modules, hardware or physics-based twins in the digital twin.
Data recording and logging are crucial components of any digital twin project. This data not only serves as the basis for simulation and testing but also facilitates debugging, system optimization and performance analysis. Effective data recording strategies can also assist in the validation of model assumptions, further enhancing system accuracy and reliability.
Digital twins are not merely simulation tools; they represent a fundamental shift in the way we can plan, design, deploy and optimize robotic automation systems in warehouses. A well-designed digital twin, factoring in the aspects outlined in this article, empowers reliable, predictable and efficient order fulfillment, catalyzing innovation and progress in customer satisfaction.
After a search of neutron stars finds preliminary evidence for hypothetical dark matter particles called axions, astrophysicists are devising new ways to spot them.

How much water a fish consumes really depends on how much salt is in its surrounding habitat. While fish do drink some water — salty or fresh, depending on their surroundings — through their mouths, they mostly absorb it through their skin and gills via osmosis.
“You’ve got to think of a fish as sort of a leaky boat in the water,” Tim Grabowski, a marine biologist at the University of Hawaii, told Live Science. “You constantly have a movement of either water or the salts that are in the water between the fish’s body and the external environment.”
