Scientists explore the evolution of neurons — ScienceDaily

Neurons, the specialized cells of the nervous system, are possibly the most complicated cell type ever to have evolved. In humans, these cells are capable of processing and transmitting vast sums of information. But how such complicated cells first came about remains a long-standing debate. Now, scientists in Japan have revealed the type of messenger …

A solar wind stream unexpectedly hit Earth at 372 miles a second

The unexpected solar wind that turned into a storm Since scientists are constantly monitoring the solar surface, they have a fairly good idea about which solar winds are headed our way and which aren’t. Based on the data, they can also predict the strength of geomagnetic storms that result from these solar winds, full of …

The Emergence of an Alternative Gravity Theory

Aug 8 2022Reviewed by Alex Smith The vast majority of galaxies, according to the accepted theory of cosmology, are encircled by a halo of dark matter particles. Despite being invisible, this halo’s mass pulls nearby galaxies in a powerful gravitational field. The dwarf galaxy NGC1427A flies through the Fornax galaxy cluster and undergoes disturbances which …
