情態副詞

you probably picture a bunch of server racks,

covered in blinking lights in a lab somewhere.

your home PC part of a super computer, for free

Folding@home started at Stanford University

but is now run from multiple sites around the world

and the goal is to research protein folding.

and what the heck is protein folding anyway?

that weightlifters drink by the bucket full.

Your body uses all sorts of different proteins

for everything from building muscle fibers

to intercellular signaling and the crucial thing

to remember about proteins is that their function

which is where the term 'folding' comes in.

After a protein is assembled it has to fold

which you can just follow simple instructions for,

protein folding is much more complicated.

You see, proteins are made up of 20 different

all 20 of them have different side chains that,

as the name implies, stick of to the side of the molecule.

When you connect a bunch of amino acids together,

linearly to form a protein, these side chains interact

with each other in ways that cause a protein to fold,

As you can imagine, the more amino acids,

the more complicated these interactions become

and the typical protein might be hundreds

And of course, it's critical for a protein to end up

For example, cells have proteins on their surfaces

and they only function because they are shaped

in a certain way that allows them to bind

kind of like two puzzle pieces coming together.

The TLDR is that understanding how proteins fold

has very important implications in medicine.

For example, understanding how viral proteins interact

is critical to finding treatments to some viral diseases.

is currently using Folding@home to research

the novel coronavirus that causes Covid-19.

The better we can understand what parts of the virus

especially the ones that bind to human cells,

the more likely it is that we can develop medicines

But anyways, this is tech quickie not biology quickie

so let's tie this all back to the Folding@home project.

It turns out that simulating protein folding patterns

In nature, proteins fold in a tiny fraction of a second

but it can take years of computer time to sort out

is to leverage spare home computing power

in order to solve these difficult problems.

All you need to do to participate like I am,

and then send back to the program servers.

You can specify how much of your PC spare computer muscle

to use, depending on how much you want it to affect

your power bill and you can also choose whether

to run the simulations only when the system is idle

The highly parallel nature of GPU architecture,
