Investigators from the Neurodegenerative Diseases Research Group at the University of Extremadura are studying signaling mediated by a pathway known as planar cell polarity (PCP), which regulates the coordinated orientation of cells during organogenesis, the process of organ formation in living organisms. This pathway has been highly conserved on the evolutionary scale, and one of its key functions in vertebrates is the regulation of the coordinated positioning of centrioles/ciliary basal cells inside cells.

This signaling pathway was discovered initially in the fruit fly genus Drosophila, although the majority of the pathway components have been retained in humans. It has likewise been observed that certain pathologies such as hydrocephaly, infertility and some kinds of cancers are associated with defective functioning of this signaling.

Under the auspices of the project EPICENTR within the Spanish national research plan, whose objective is to study the planar polarisation of centrioles in epithelial cells, the UEx researchers have now published the first results of their investigation in the journal Development. These results are related to the polarised positioning mechanism of centrioles in Drosophila and its correlation with actin.

The Allen Institute has released an open database of live human brain cells.

But many experts, even those mindful of such risks, have a more positive outlook, especially in health-care and possibly in education.

Most experts canvassed by Pew say artificial intelligence will leave most of us better off by 2030. But there are fears about jobs and mayhem.

Our future on Earth may also be our past. In a study published Monday (Dec. 10, 2018) in the Proceedings of the National Academy of Sciences, researchers show that humans are reversing a long-term cooling trend tracing back at least 50 million years. And it’s taken just two centuries.

While space mining is still a decade or so off, next year the industry is ramping up their efforts.

NASA offered to give Stephen Curry a tour of its lunar labs in Houston after the NBA superstar expressed doubts on the moon landings.

Three-time NBA champion Stephen Curry on Tuesday signaled that he is willing to take NASA up on its offer to tour its lunar lab in Houston after his pronouncement this week that he does not believe humans ever walked on the Moon.

During the “Winging It” podcast released on Monday, the Golden State Warriors guard asked fellow players Vince Carter and Kent Bazemore whether they believed humans had ever been to the Moon.
