The Soap Bubble Nebula

Adrift in the rich star fields of the constellation Cygnus, this lovely, symmetric nebula was only recognized a few years ago and does not yet appear in some astronomical catalogs. In fact, amateur astronomer Dave Jurasevich identified it as a nebula on 2008 July 6 in his images of the complex Cygnus region that included the Crescent Nebula (NGC 6888). He subsequently notified the International Astronomical Union. Only eleven days later the same object was independently identified by Mel Helm at Sierra Remote Observatories, imaged by Keith Quattrocchi and Helm, and also submitted to the IAU as a potentially unknown nebula. The nebula, appearing on the left of the featured image, is now known as the Soap Bubble Nebula. What is the newly recognized nebula? Most probably it is a planetary nebula, a final phase in the life of a sun-like star.

Do viruses make us smarter?

A new study from Lund University in Sweden indicates that inherited viruses that are millions of years old play an important role in building up the complex networks that characterise the human brain.

Researchers have long been aware that endogenous retroviruses constitute around five per cent of our DNA. For many years, they were considered junk DNA of no real use, a side-effect of our evolutionary journey.

In the current study, Johan Jakobsson and his colleagues show that retroviruses seem to play a central role in the basic functions of the brain, more specifically in the regulation of which genes are to be expressed, and when. The findings indicate that, over the course of evolution, the viruses took an increasingly firm hold on the steering wheel in our cellular machinery. The reason the viruses are activated specifically in the brain is probably due to the fact that tumours cannot form in nerve cells, unlike in other tissues.

“We have been able to observe that these viruses are activated specifically in the brain cells and have an important regulatory role. We believe that the role of retroviruses can contribute to explaining why brain cells in particular are so dynamic and multifaceted in their function. It may also be the case that the viruses’ more or less complex functions in various species can help us to understand why we are so different”, says Johan Jakobsson, head of the research team for molecular neurogenetics at Lund University.

The article, based on studies of neural stem cells, shows that these cells use a particular molecular mechanism to control the activation processes of the retroviruses. The findings provide us with a complex insight into the innermost workings of the most basal functions of the nerve cells. At the same time, the results open up potential for new research paths concerning brain diseases linked to genetic factors.

“I believe that this can lead to new, exciting studies on the diseases of the brain. Currently, when we look for genetic factors linked to various diseases, we usually look for the genes we are familiar with, which make up a mere two per cent of the genome. Now we are opening up the possibility of looking at a much larger part of the genetic material which was previously considered unimportant. The image of the brain becomes more complex, but the area in which to search for errors linked to diseases with a genetic component, such as neurodegenerative diseases, psychiatric illness and brain tumours, also increases”.

First Notable Solar Flare of 2015

The sun emitted a mid-level solar flare, peaking at 11:24 p.m. EST on Jan. 12, 2015. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

January 13th 532: Nika riots begin

On this day in 532 AD one of the deadliest riots in history, the Nika riots, began in Constantinople, the capital of Byzantium (the Eastern Roman Empire). The chaos emerged from long-standing sporting rivalries between opposing chariot racing teams - the Blues and the Greens - each of whom attracted fanatical support that often spilled over into violence. The divisions may have gone further than sport, as it has often been suggested that the Blues and the Greens essentially represented opposing political parties in the Byzantine Empire. The riots occurred during the reign of the unpopular Emperor Justinian, whose military endeavors were having a heavy burden on increasingly disgruntled taxpayers. Justinian’s wife, the Empress Theodora, was a controversial figure because of her humble working class origins and her political influence over her husband. The tensions came to a head when Justinian sent in troops to quell fighting between Greens and Blues, and condemned the ringleaders to death, thus ending his support for the Blues. When both a Green and a Blue escaped their execution, the factions were united in the cause to have the men pardoned. On January 13th, during a race at Constantinople’s Hippodrome stadium, both factions vented their anger at the emperor with chants of "Nika!" (‘Conquer/Win’). Five days of rioting ensued, which saw the mob burn down large portions of the imperial capital and call for the emperor to be deposed. Justinian wanted to flee the city, but Theodora rebuked him for his cowardice, and he therefore stayed and approved a plan to isolate the rioting factions in the Hippodrome. The imperial forces descended on the stadium, killing 30,000 of the rioters, which was around 10% of the city’s population at the time. With the violence of the Nika riots in the past, change came to Byzantium in the form of a decline in both the power of the factions and the prominence of chariot-racing.
