New Coronavirus Strain !

The other mutation - a H69/V70 deletion, in which a small part of the spike is removed

has emerged several times before, including famously in infected mink.

Work by Prof Ravi Gupta at the University of Cambridge has suggested this mutation increases infectivity

two-fold in lab experiments.

Studies by the same group suggest the deletion makes antibodies from the blood of survivors

less effective at attacking the virus.

"It is rapidly increasing,

that's what's worried government, we are worried, most scientists are worried."

Mutation out of control !

Researchers have recorded thousands of tiny modifications in the genetic material of the coronavirus

as it has hopscotched across the world.

Some variants become more common in a population simply by luck,

not because the changes somehow supercharge the virus.

This is getting scarier by the Mutations ~

and if the virus genetic code change it will be immune to the Vaccine !

But as it becomes more difficult for the pathogen to survive

— because of vaccinations and growing immunity in human populations —

researchers also expect the virus to gain useful mutations enabling it to spread more easily

or to escape detection by the immune system.

Will the vaccines work against the new variant?

Almost certainly yes, or at least for now.

All three leading vaccines develop an immune response against the existing spike

which is why the question comes up.

Vaccines train the immune system to attack several different parts of the virus,

so even though part of the spike has mutated,

the vaccines should still work.

The good news is that the technology used in the Pfizer-BioNTech and Moderna vaccines

is much easier to adjust and update than conventional vaccines.

The new vaccines also generate a massive immune response, so the coronavirus may need many mutations

over years before the vaccines must be tweaked

Centers for Disease Control and Prevention and other government agencies should set up a national system

to link viral sequence databases with on-the-ground data

— like whether an infection occurred despite vaccination.

This variant is just the latest to show the virus is continuing to adapt as it infects more and more of us.

Perhaps the most perplexing aspect of AT&T Stadium, otherwise known as “Jerry World,” is the glare from the sun that bursts through the windows and shines directly onto the field. Time and time again the glare has impacted players’ visibility during games, yet Jerry Jones refuses to make any changes to account for the sun.

Rather than install curtains, Jones has previously said he feels it’s a home-field advantage to have that type of stadium factor impacting games. Well, the glare ended up benefitting the Chiefs early into Thursday’s Thanksgiving game, as a pass from Dak Prescott to George Pickens fell incomplete, at least in part due to the impact of the sun’s glare.

SerenaThis batting performance by the West Indies in the second innings blew me away. I kept closing my eyes and then rubbing and opening them again and sat transfixed as I watch that unbelievable partnership between John Campbell and Shai Hope. What a magnificent performance by these two! It just goes to show that patience, determination and effort can go a long way to improve the performances of the West Indies team. Let us hope that this effort by West Indies batsmen would not be a one-off performance, but will be the beginning of a renewed effort to improve the performances of the team, going forward.(13.10.2025, 09:28)(09:28)0

"As a competitor, you want to be the starter. But I prepare to be the starter, I know I'm a starter in this league.

But you have to be able to be grateful for your role...my role right now is to assist Russ and Jaxson to be the best that they can be while preparing to be the best that I can be.

No matter if I'm 3, 33, this is my first year being number 19, so it's always a first for everything.
