There are fossils of viruses, of sorts, preserved in the DNA of the hosts that they’ve infected. Including you. This molecular fossil trail can help us understand where viruses came from, how they evolved and it can even help us tackle the biggest question of all: Are viruses alive?

Summary: 2022 has been a fantastic year for neuroscience and brain science research. Here, we take a look back over some of the most popular neuroscience research articles of the year.

For over 20 years, Neuroscience News has reported on the latest, ground-breaking neuroscience research. Every year, we like to take a look back at some of the most popular articles we have published on the website.

The researchers conducted a deep dive into the genetics of these tumours, both during the slow chronic phase and after the disease had transformed into the aggressive form. Researchers have identified an important transition point in the shift from chronic to aggressive blood cancer by conducting experiments in mice, providing a new intervention point for hampering the progress of the disease, according to a study.

This year marks the 10th anniversary of the discovery of the Higgs particle. Now we can see it in perspective.

To understand its significance, imagine an ocean planet where intelligent fish evolve and start to make theories of how things move. They do experiments and deduce equations but it is a messy hodgepodge, because the fish, taking their ever-present environment for granted, think of their ocean as “empty space.” After decades of work, though, some realize that by postulating that “empty space” is a medium—ocean—that has mass and motion of its own, you can account for everything using simple, elegant laws (namely, Newton’s laws). Next, the fish start to wonder what their hypothetical ocean is made of. They boil some ocean, do some sophisticated spectroscopy, and ultimately identify water molecules. Imagined beauty guided them to concrete truth.
