In this animation, the differences between bacteria and viruses are explained. How does a bacterium or virus enter the body? And what are typical complaints of a viral or bacterial infection? Finally, the different treatments for bacterial and viral infections are mentioned.

Health TV makes complex medical information easy to understand. With 2D and 3D animations checked by medical doctors, we give information on certain diseases: what is it, wat are the causes and how is it treated? Subscribe to our Youtube channel and learn more about your health!

How do viruses make more copies of themselves? They do this by taking over human cells. When a virus infects a cell, it hijacks the protein-making machinery of the cell by releasing its own genetic code, or instructions, into the cell. Now, instead of making proteins for the body, the cell starts working for the virus, helping it replicate. The cell makes more and more virus particles that are released to go on and infect more cells.

We humans have always been explorers. The great civilizations that have arisen across the world are owed to our restless ancestors. These days, there’s not much of Earth left to explore. But if we look up, there’s a whole universe out there waiting for us. Future generations may one day explore the cosmos and even settle entire other galaxies. But there is a hard limit to how much of the universe we can expand into. So, how big can humanity get?

Researchers assess the effectiveness of a phenotype-tailored lifestyle intervention on weight loss in obese adults.

A tiny computer chip was implanted into seven mice at once

The implant created by the engineers at Columbia is record-breakingly small, but it’s also breaking new ground in simply existing as a wholly functional, electronic circuit whose total volume is less than 0.1 cubic millimeter. In other words, it’s the size of a dust mite, not to mention far more compact than the world’s smallest computer, which is a cube-shaped device precisely 0.01-inches (0.3 mm) on each side. The smaller, new chip is only visible with a microscope, and pushed the envelope in power-sourcing and communications ingenuity design.

Typically, small electronics feature radio frequency (RF) modules capable of transmitting and receiving electromagnetic signals, this method generates wavelengths too large to originate from devices as small as the new one. Alternatively, ultrasound wavelengths are far smaller at specific frequencies because the speed of sound is a lot slower than the speed of light at which all electromagnetic waves move. Consequently, the Colombia team of engineers integrated a piezoelectric transducer capable of functioning like an “antenna” for wireless communication and powering using ultrasound waves.
