PI3K/AKT signaling mediates stress-inducible amyloid formation through c-Myc

Lacroix et al. demonstrate that heat-induced activation of the PI3K/AKT signaling cascade drives the formation of functional amyloid aggregates that protect cells from harsh environmental conditions. Here, activation of PI3K and AKT represses GSK3-mediated degradation of c-Myc, leading to upregulation of nucleating noncoding RNAs that mediate this physiological amyloidogenic event.

Researchers identify a dual origin of cells controlling puberty and reproduction

Researchers at the Francis Crick Institute have shown that gonadotrophs, cells in the pituitary gland with a key role in puberty and reproduction, come from two different populations, with the majority produced after birth rather than in the embryo, as previously thought.

Record precision achieved in measuring muonic helium-3 nucleus radius

An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium-3 with unprecedented precision. The results are an important stress test for theories and future experiments in atomic physics.

1.97007 femtometer (quadrillionths of a meter): That’s how unimaginably tiny the radius of the atomic nucleus of helium-3 is. This is the result of an experiment at PSI that has now been published in the journal Science.

More than 40 researchers from international institutes collaborated to develop and implement a method that enables measurements with unprecedented precision. This sets new standards for theories and further experiments in nuclear and .
