Why is the sky blue? From a Newton's apple to a large Hadron collider.

The extraordinarily long-lasting, record-breaking gamma-ray burst crossed the Earth's trajectory on Sunday, October 9, 2022. The source of that GRB could be just the born black hole that pulled the supernova remnants inside it. That kind of case where a black hole pulls the molecular cloud around the exploded star back into the black hole can form extraordinary long-term GRBs. The knowledge of the GRB is limited.  Those eruptions remain for a very short time. And they can cause problems for probes and manned spacecraft. If those GRBs are impacting those things. On Earth magnetic field and atmosphere protect people and computers. But in space, there is not that kind of protection. And that means the GRB can be very dangerous.  But another reason why researchers are researching that phenomenon is that it is the most high-energy reaction in the universe. If researchers can capture the GRB they could create energy for years.  And there is another thing that can be possible in...

The image above introduces how the new honeycomb quantum material behaves. The text below the original image goes like this "By exposing a honeycomb-like material with a specific kind of magnetic field, yellow arrow, researchers can create order among the loop currents, light blue, within that material. Electrons, in green, can then pass through the material much more easily.

And that makes it possible to create long-distance probes where the entire craft is a quantum computer. That kind of system can operate at...

Credit: DGIST (Daegu Gyeongbuk Institute of Science and Technology) (Scitechdaily.com/10,000 Times Quicker: New Breakthrough Could Change the Field of Medical Microrobots) Nanorobots are powerful tools. But the problem is how to control them and how to produce enough nanomachines.  "There are many approaches to building microrobots with the goal of minimally invasive targeted precision treatment. The most popular of them is the ultra-fine 3D printing process known as the two-photon polymerization method, which triggers polymerization in synthetic resin by intersecting two lasers". (SciTechDaily.com/10,000 Times Quicker: New Breakthrough Could Change the Field of Medical Microrobots) New production methods can increase microrobot production. And that can make medical nanorobots more common and effective. When the numb...

Things like meat-eating bacteria are the most horrifying organisms on Earth. But what if researchers can control those bacteria? What if they can drive those bacteria to the tumors and give them order to begin eating in that precise place? This thing can make it possible to remove tumors by using extreme accuracy.  Researchers can make that thing true, by using microchips that control the DNA plasmid. Those microchips are turning the DNA plasmid's position that controls the bacteria's functions.  Bacteria have long fibers that are made of a single protein. By moving those fibers like screws. The bacteria use them as propellers. And that thing makes them move. What makes that thing interesting? Researchers can copy the bacteria's movement to nano- and miniature machines.  If we are thinking of a miniature submarine that size is the same as some medical capsules that kind of miniature device can swim in the cooling water system of a nuclear reactor or a chemical plant's w...

"The dwarf galaxy NGC1427A flies through the Fornax galaxy cluster and undergoes disturbances that would not be possible if this galaxy were surrounded by a heavy and extended dark matter halo, as required by standard cosmology. Credit: ESO" (ScitechDaily.com/New Discovery Indicates an Alternative Gravity Theory) The dwarf galaxies are interesting things. Dwarf galaxies are small star clusters, colder than giant galaxies and closer than ultra-diffuse galaxies or UDGs. That is very far from us.  Conditions in dwarf galaxies are sometimes similar to the UDGs. That thing is true if there are lots of old stars in the dwarf galaxy.  Some dwarf galaxies are following Milky Way. They are not as bright as Milky Way or Andromeda galaxy. And that allows for observing black holes in the middle of those small galaxies. In the cases of the Milky Way and Andromeda, the brightness of the dust hides the black hole behind them.  Their lack of material is the result of larger galaxies' gra...
