Aurora in the Backyard



On the night of March 17/18 this umbrella of northern lights unfolded over backyards in Vallentuna, Sweden about 30 kilometers north of Stockholm. A result of the strongest geomagnetic storm of this solar cycle, auroral displays were captured on that night from back and front yards at even lower latitudes, including sightings in the midwestern United States. A boon for aurora hunting skywatchers, the space storm began building when a coronal mass ejection, launched by solar activity some two days earlier, struck planet Earth's magnetosphere. So what's the name of the backyard observatory on the right of the wide field view? That's Carpe Noctem Observatory, of course.

Listening to classical music modulates genes that are responsible for brain functions


Although listening to music is common in all societies, the biological determinants of listening to music are largely unknown. According to a latest study, listening to classical music enhanced the activity of genes involved in dopamine secretion and transport, synaptic neurotransmission, learning and memory, and down-regulated the genes mediating neurodegeneration. Several of the up-regulated genes were known to be responsible for song learning and singing in songbirds, suggesting a common evolutionary background of sound perception across species.


Listening to music represents a complex cognitive function of the human brain, which is known to induce several neuronal and physiological changes. However, the molecular background underlying the effects of listening to music is largely unknown. A Finnish study group has investigated how listening to classical music affected the gene expression profiles of both musically experienced and inexperienced participants. All the participants listened to W.A. Mozart’s violin concert Nr 3, G-major, K.216 that lasts 20 minutes.


Listening to music enhanced the activity of genes involved in dopamine secretion and transport, synaptic function, learning and memory. One of the most up-regulated genes, synuclein-alpha (SNCA) is a known risk gene for Parkinson’s disease that is located in the strongest linkage region of musical aptitude. SNCA is also known to contribute to song learning in songbirds.


“The up-regulation of several genes that are known to be responsible for song learning and singing in songbirds suggest a shared evolutionary background of sound perception between vocalizing birds and humans”, says Dr. Irma Järvelä, the leader of the study.


In contrast, listening to music down-regulated genes that are associated with neurodegeneration, referring to a neuroprotective role of music.


“The effect was only detectable in musically experienced participants, suggesting the importance of familiarity and experience in mediating music-induced effects”, researchers remark.


The findings give new information about the molecular genetic background of music perception and evolution, and may give further insights about the molecular mechanisms underlying music therapy.

2. Imprison your hairdresser so no one ever finds out?


3. Wear wigs made from prisoners’ hair?


4. All of the above?

Guys, deadbolts aren’t totally safe. This is just one of several ways I’ve seen them opened (via YouTube videos). If you really want to be safe, consider investing in a flip-latch.


You can pick them up at ACE hardware (or any other hardware store), and you install them on the inside of the door on the doorframe. They flip and lock really tight (you typically have to lean your weight into the door to secure it) and they can’t be opened from the outside as far as I know.



Another reason I will never sleep easy in a hotel for the rest of my life.

sixpenceee:



Doctors in Chile have been left stumped after being presented with a patient who apparently cries tears of blood. Yaritza Oliva, a 20-year-old from the city of Purranque, cries blood red tears several times a day after being afflicted by a mysterious condition earlier this month.


After seeking medical assistance, she was prescribed eye drops to ease the burning pain she said was “indescribable.” Her local hospital ruled out both an eye infection and conjunctivitis, believing that she may be suffering from a rare condition known as haemolacria, although it has yet to be officially diagnosed.



Several case of haemolacria have surfaced in recent years, although very little is known about the condition or its causes. (Source)

Harriet Quimby was one of the greatest early female aviators. In 1911, Quimby became the first woman in the country to get her pilot’s license with the Aero Club of America. When she wasn’t busy flying planes recreationally, Harriet Quimby enjoyed quite a successful career in Hollywood by writing screenplays that were turned into silent shorts. Eventually, Quimby decided to embark on an ambitious task: flying across the English channel. No woman had done it before.


She completed flew across on April 16, 1912. She took off from Dover and landed 59 minutes later on a beach near Calais in France. She officially became the first female pilot to fly the Channel, but her feat drew little interest from the media. Why? On April 15, 1912, the Titanic sank during its maiden voyage.
