Cleared the Pad For a hot minute, it looked like SpaceX had done the seemingly impossible. The space company's gigantic Starship prototype spacecraft and Super Heavy booster officially cleared the launch pad this morning at the company's South Texas testing facilities, an epic conclusion to many years of development.

Potatoes are the third most important food crop in the world after rice and wheat in terms of human consumption. But globally, potato production is threatened by potato late blight, one of the most devastating potato diseases, which causes 3–10 billion euros in yield loss and management costs annually.

New insight into proteins called "pioneer factors" helps to explain their unusual ability to open up the typically dense genetic material within our cells. This behavior makes the genetic material accessible for proteins involved in important cellular processes, such as DNA replication and repair, gene expression, and the creation of proteins.

Hello! I'm seeking help for an issue I have where I am unable to keep a still imagination in my head. For example, if I were to imagine being in my bedroom, I would subsequently impulsively switch perspectives to a different angle of the room or just simply move around without consciously commanding my mind to it. Does anyone have any mitigating methods or explanations for this phenomenon? Thank
