Researchers found how HIV cheats the immune system.

The thing how HIV takes entire cells into control is been a mystery. The researchers found the answer. The virus' genetic material is packed in the ball, or pore there are thousands of proteins. HIV uses that thing to cheat the cell and transport its DNA to the nucleus. 

Another way would be that HIV takes some cell organelles under control by sending the RNA to that organelle. That thing allows the virus to order cell organelles to produce new viruses. But in this method, the HIV starts to take the entire cell under control. 

And the thing how that virus makes this thing is interesting. HIV just transforms the mechanism. That is created for the cell's protection to carry its DNA into the nucleus. Normally. The mechanism where the cell uses a carrier involves lots of proteins. And that protects it against viruses. That key is not very easy to capture. 

The pore there is thousands of proteins means that HIV has a master key that fits into the T-cell keyhole. Normally when a virus infects cells, it sends marks that it's infected. And that thing calls the T-cells to mark it. But when the T-cell itself is infected. There is no mark. That makes it call other cells to destroy it. 

That causes a situation in which the T-cell starts to produce HIV viruses. The pore that involves the T-cell detection proteins makes those cells helpless against HIV. First, the infection travels in T-cells. The role of the T-cells is that they mark infected cells. But the problem is that the infected T-cell can't mark itself. 

The reason for researchers are interested in this mechanism is simple. They need it to create vaccines. But the other thing is that researchers want to use this thing as the system, which makes HIV cheat cells is that they want to use it in biotechnology. This system gives the ultimate ability to transport genetic material into the cells. The ability to cheat the DNA makes it possible to give gene therapy using only injections that are as easy as vaccines. 

It can also make it possible to increase the effectiveness of gene therapy. The system can inject pores there is DNA into the human body. There the DNA makes infected cells create new viruses. And that gives the possibility to give extensive gene therapy.

Researchers think that the multiverse is not fiction anymore.

Multiverse means that our universe is one of many universes. The reason why researchers and scientists believe that this is true is that logical. About 50 years ago people didn't know that there were other solar systems. Exoplanets were only theories in the 80's.  About 400 years ago people thought that our Sun was the only star in the universe. Edvin Hubble proved that our galaxy, Milky Way is one of many galaxies. Then researchers found that galaxies form groups, and supergroups. That means that today we think that the universe, where we live is the ultimate supergroup of galactic supergroups. And logically thinking there should be other universes. We believe that the universe began its existence in an event or series of events called the Big Bang. That event did not begin, because the energy that formed material should come from somewhere. The Big Bang was not one "bang" or explosion. It was a series of events where material took form. Or the energy level that it h...

Spinning cylinders prove a 50-year-old physics problem.

"Scientists at the University of Southampton have experimentally proven the Zel’dovich effect by amplifying electromagnetic waves using a spinning metal cylinder, confirming a theoretical prediction from the 1970s and opening new avenues in technology and quantum physics.

Using relatively simple equipment – a resonant circuit interacting with a spinning metal cylinder – and by creating the specific conditions required, we have now been able to do this.” (ScitechDaily, 50-Year-Old Physics Theory Proven for the First Time With Electromagnetic Waves) Researchers amplified electromagnetic waves using spinning metal cylinders.

What makes it hard to create a room-temperature superconductor?

"The discovery of wave-like Cooper pairs in Kagome metals introduces a new era in superconductivity research, offering potential for innovative quantum devices and superconducting electronics, driven by theoretical predictions and recent experimental validations. Credit: SciTechDaily.com" (ScitechDaily, Kagome Metals Unlocked: A New Dimension of Superconductivity) "Superconductivity is a set of physical properties observed in superconductors: materials where electrical resistance vanishes and magnetic fields are expelled from the material. Unlike an ordinary metallic conductor, whose resistance decreases gradually as its temperature is lowered, even down to near absolute zero, a superconductor has a characteristic critical temperature below which the resistance drops abruptly to zero. An electric current through a loop of superconducting wire can persist indefinitely with no power source" (Wikipedia, Superconductivity) Theoretically, a superconducting electric circu...
