How fast is gravity?

Posted by in category: physics

Gravity is the most familiar of the known forces, but it seems to be eternal and unchanging. However, scientists believe that gravity moves with a specific speed. In this video, Fermilab’s Dr. Don Lincoln describes a fascinating observation that definitively measures the speed of gravity.

Viral Budding of the SARS-CoV-2 virus — NanoBiology Course 2020 — Tuesday Group

Posted by in categories: biotech/medical, chemistry, particle physics

In this video students of the Maastricht Science Program NanoBiology Course 2020, show their explanation of the SARS-CoV-2 viral budding. Using CellPAINT, UCFS Chimera and their creativity they explain the nanobiology of how the SARS-CoV-2 virion can bud and leave the cell.

Viruses are not living things. They are just complicated assemblies of molecules, in particular macromolecules such as proteins, oligonucleotides, combined with lipids and carbohydrates. A virus cannot function or reproduce by itself. It needs a host cell.

A Virus Attacks a Cell

Posted by in categories: biotech/medical, education

https://youtube.com/watch?v=jkNxmTrrZSk

“Like a lock and key” — this is the description of how viruses can get into our cells. Viruses use special proteins on their surface to enter cells. They do this because they need our cells to reproduce. But viruses can only enter certain cells. They use proteins on their surface that act like keys to unlock human cell receptors to invade and infect cells.

Physicists Say Aliens May Be Using Black Holes as Quantum Computers

Posted by in categories: alien life, computing, existential risks, quantum physics

If life is common in our Universe, and we have every reason to suspect it is, why do we not see evidence of it everywhere? This is the essence of the Fermi Paradox, a question that has plagued astronomers and cosmologists almost since the birth of modern astronomy.

It is also the reasoning behind the Hart-Tipler Conjecture, one of the many (many!) proposed resolutions, which asserts that if advanced life had emerged in our galaxy sometime in the past, we would see signs of their activity everywhere we looked. Possible indications include self-replicating probes, megastructures, and other Type III-like activity.
