I doubt the validity of this #diabetes cell therapy study. Since the 90s, we’ve known removing class I & II from cells should make them targets for NK cells. CD47 alone shouldn't be enough to hide. Needs much more data and scrutiny.

This company claimed to β€˜de-extinct’ dire wolves. Then the fighting started. Colossal’s bold announcements have drawn criticism from many scientists, but the billion-dollar firm is not backing down.

β€œI don’t think they de-extincted anything”

If Colossal Bio (@colossal) is eager to do gene editing, why not focus on truly useful work like gene edits to help Tasmanian devils fight cancer? Enough megalomania and George Church’s PR stunts.

"The Storm Before the Storm" shows Rome’s Republic cracking, not by breaking laws, but by ignoring unwritten norms. Economic inequality, prejudice over citizenship, and unchecked individual ambition overwhelmed a system never built to run an empire.

You can’t seriously challenge the government in Georgia when 50 thousand tickets just sold to attend a Justin Timberlake concert. Who even listens to him anymore, let alone during a political crisis?

It is obvious the Georgian Dream team made some serious miscalculations. The West is determined to put Russia in the same position it was in after the Crimean War in 1856. It will not allow Russia to extend influence beyond its own borders. The only question is how long it will take.

Back then, one patient death was enough to shut down gene therapy research for years. Now, it took three deaths and firm FDA action to stop a company from continuing unfazed.

'Users could β€œlaunch a bunch of Comet assistant jobs” and then, as Srinivas puts it, spend their time on other things while the AI works.'

But at that pace, there may not be much 'other work' left for white-collar workers.

"administration of lipid particles loaded with RNA coding for tumour-unspecific antigens"

So much for the painstaking search for tumor-specific #neoantigens. Turns out you can just throw in whatever, or even nothing at all, and it still somehow works.

The Georgian Dream government seems to ignore that much of Georgia’s current confidence in dealing with the EU and US was built on their financial support. Challenging these partners as equals is premature unless Georgia repays its debts. True sovereignty demands it.

In my view, the question of T helper cell differentiation should be divided into: (A) stochastic phenotype acquisition by naΓ―ve T cells via innate signals, and (B) pathological responses from cross-reactive, pre-existing memory T cells.
