New findings will help scientists trace a black hole.

A black hole is a place in space where the pull of gravity is so strong not even light can escape it. Astronomers classify black holes into three categories by size: miniature, stellar, and supermassive black holes. Miniature black holes could have a mass smaller than our Sun and supermassive black holes could have a mass equivalent to billions of our Sun.

From robotics to connectivity, technological transformation offers tremendous possibility for the farming and food sectors.

In removing cilia from human pluripotent stem cells, Freedman and his colleagues sought to understand what would happen in their subsequent transformation into tissues and organoids. As it happened, the cilia-free stem cells appeared normal but were unable to fully realize new forms.

“It was surprising to me that, at a certain point after they were turning into tissues, they seemed to break down,” Freedman said. “They struggled to transform into anything sophisticated. I think one lesson from this is that the cilia help get cells through their final stage of development.”

It was first reported in 2000 that PKD could stem from defects in cilia, but the mechanism of damage that causes cysts to form has escaped scientists. By creating cilia-free stem cells that harbor disease, Freedman said, the researchers now have a framework with which to test and compare molecular actions in the cilia.

Yet on April 28, 2022, each instrument’s alignment was completed, with a ~20 year lifetime expected. Both telescope and team performed dazzlingly, surpassing expectations overall.

First: the pristine, on-course launch conserved fuel purposed for course-correction.

Estimates put this industry’s worth at a staggering $610 billion by 2025. 😳

The Renaissance philosopher Montaigne quipped that “death has us by the scruff of the neck at every moment.” He could have added: until, finally, it strangles us. But what if we knew how to escape death’s chokehold? What if we could avoid death and live forever?

Immortality might seem like the stuff of science fiction, yet it’s increasingly becoming the focus of real science. In 2013, Google launched Calico, a biotech firm whose objective is to “solve” death. PayPal co-founder Peter Thiel, meanwhile, has pledged to “fight” death. And last year, it was reported Amazon chairman Jeff Bezos had invested in Altos Labs, a company that plans to “rejuvenate” cells in order to “reverse disease.” (Bezos owns The Washington Post.)
