Let’s take a closer look at this protein structure determined using AlphaFold2. This protein structure is part of a huge molecular structure in the human body. More than a thousand proteins form a pore through the membrane surrounding the cell nucleus. Animation: ©Terezia Kovalova/The Royal Swedish Academy of Sciences #NobelPrize

That "last day" is described in 1 Thessalonians 4:15-17 "For this we say to you by the word of the Lord, We who are alive and remain until the coming of the Lord shall by no means precede those who are asleep, for the Lord Himself shall descend from heaven with a signal, with the shouting of the archangel, and with the sound of the trump of God; and they that are dead in Christ shall rise first; then we who are alive and remain shall be caught up together with them in the clouds in the twinkling of an eye to meet the Lord in the air, and so shall we ever be with the Lord.”

A lot of you are thinking that the spring which we will supply to Prakash Dadlani will be produced at the speed of 1304 ppm. That’s not true. All springs are not made on one kind of machine. The CNC machine we built that produces springs up to 1304 ppm manufactures compression springs. Whereas, the springs for Prakash bhai will be made on one of our 12-axis CNC wire forming machine. And on this the speed is much slower but it has flexibility to produce a number of different kinds of springs and wire forms. The design, type, materials, wire diameter and profile, features and precision of the springs defines what kind of machine will be used. It’s not one machine that does it all. This video is of that springs being manufactured on our other CNC machine. Also, the operator is setting the spring up that is why he is using his hands. Once it’s in production, there’s a crate underneath the machine for the springs.

The question of why black violence around the globe is epidemic-----remains a complete mystery to experts, politicians, and most anthropologists. For your average common-sense-Joe, the “why” isn’t a puzzle, the stats are real.

OMG What Is This? Holographic Object in the Sky The witness said she saw this with her own eyes — not through glass, not a reflection. The object moved behind the trees and held its shape, almost holographic in nature. #MrMBB333 #UAP #SkyPhenomenon

The FBI visited this tiktoker. (fbi visit in second video). A lot of them are pushing the vague "its time" theme, which you all know what that's alluding to.

RUMOR | Microsoft might not launch this year's Call Of Duty on Xbox Game Pass “It'll be interesting to see... if they take Call of Duty out of Game Pass this year — which is a possibility from what I've heard — I think it'll reveal some of the cracks in the strategy [with Game Pass] possibly,” via: Jez Corden

Here’s a random thought… If Call Of Duty is the actual reason for the Xbox Game Pass Price Hike you could: • Revert the Prices back to what they were • Don’t put COD in Game Pass Ultimate for 3-6 Months • Give Game Pass Ultimate Subscribers 500 COD Coins a Month

This is what the Bedrock Operator sees on a job site. The camera feed shows what a human operator would see. The LiDAR point cloud shows what the machine knows, the full geometry of the environment, rendered in real time, down to millimeter precision. The excavator's position, the bucket's angle, the shape of the cut: all of it mapped and updated continuously. This is the sensing foundation that makes autonomous operation possible. Before a machine can act safely and accurately, it has to understand its environment completely.
