“The abolition of gender studies is a way of further guaranteeing impunity to the elite men whose contempt for and exploitation of women and girls apparently knew no bounds, whether they actually slept with the women on offer or simply shared Epstein’s fantasies in order to gain influence.”

Si eres clase trabajadora y votas a VOX, revisa sus votos: en contra de la subida del SMI, la reforma laboral, la revalorización de pensiones, las ayudas al transporte y los permisos de paternidad y maternidad.

Indian writer Arundhati Roy says she was cancelling her planned participation in the Berlin Film Festival over comments from jury president Wim Wenders that the festival had to “stay out of politics” in response to a question on Gaza.

In incredible news, the European Parliament has voted overwhelmingly for "The Full Recognition Of Trans Women As Women."

Even the center-right European People's Party voted for the declaration.

It will form a foundation for their position at the UN Commission on the Status of Women.

Our latest.
European Parliament Votes Overwhelmingly For "The Full Recognition Of Trans Women As Women"
The resolution, though nonbinding, is a significant shot at those who seek to erode transgender rights on the continent.

Los investigadores inciden en que los ingresos percibidos por el despacho fundado por el exministro coincidieron con la tramitación de las reformas fiscales impulsadas por el propio Montoro.

And last, a short animation showing what the two reactions look like: first we have self-synthesis, i.e. the ribozyme making a new copy of itself (+ strand). Then we have the synthesis of the complementary strand, i.e. the ribozyme making a copy of the template encoding itself (- strand).

To confirm that QT45 could synthesize complex sequences, we showed that it can make another ribozyme (the hammerhead ribozyme). This is a key functionality in any RNA world scenario, previously only observed in the large class I polymerases.

QT45 shows general RNA polymerase activity using trinucleotide building blocks, aka triplets (+ a touch with di-/mononucleotides) and works fully via tertiary interactions. We describe this as acting “in trans” rather than “in cis”, this is critical if you need to be able to copy any sequence.

We took a leap of faith and started a search for shorter polymerases in random RNA sequence pools. We found three ribozymes, but one really stood out of the pack for its activity and variety of sequences it could copy. We named it “QT45”, as it is Quite Tiny and only 45 nucleotides long.

For 30+ years we and others have been evolving RNA polymerase ribozymes with the goal of building a self-replicating RNA-based system. These ribozymes are long and complex, which we thought was necessary for their function, but also prevented us from getting self-synthesis to work in the lab.

First of all, why RNA?

RNA was first proposed in the late 60s as a solution to the chicken and egg problem of what came first between DNA, RNA, and proteins. If RNA could drive its own replication, then potentially a single polymer could have kickstarted the process of heredity and evolution.

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?

Excited to share our latest work in @science.org on a new small polymerase.

You can't... repeal... a scientific finding. At that point it's just called lying about it.

In terms of what cures are being lost:

- Epstein-Barr virus is perhaps the major trigger for multiple sclerosis
- herpes simplex virus causes cold sores, genital herpes, infections in babies, deadly meningitis
- shingles virus causes an intensely painful disease

Estoy un poquito hasta los cojones de la gente que cree que quejarse del sistema o denunciar la discriminación es algo malo o contenido negativo.

Es que la polarización, es que te quejas por todo, es que bla, bla, bla...
