Return at Sunrise



Thursday, shortly after local sunrise over central Asia, this Soyuz spacecraft floated over a sea of golden clouds during its descent by parachute through planet Earth's dense atmosphere. On board were Expedition 42 commander Barry Wilmore of NASA and Alexander Samokutyaev and Elena Serova of the Russian Federal Space Agency (Roscosmos). Touch down was at approximately 10:07 p.m. EDT (8:07 a.m. March 12, Kazakh time) southeast of Zhezkazgan, Kazakhstan. The three were returning from low Earth orbit, after almost six months on the International Space Station as members of the Expedition 41 and Expedition 42 crews.

great now i feel million times less safe with a deadbolt



Reblogging for the comment



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.

'Ouch zone' in the brain


Researchers at the Oxford Centre for Functional Magnetic Resonance Imaging of the Brain used a new brain imaging technique to look at people experiencing pain over many hours. The results, published in the journal Nature Neuroscience, show that activity in only one brain area, the dorsal posterior insula, reflected the participants’ ratings of how much the pain hurt.


'We have identified the brain area likely to be responsible for the core, 'it hurts', experience of pain,' said Professor Irene Tracey, University of Oxford, whose team made the discovery. 'Pain is a complex, multidimensional experience, which causes activity in many brain regions involved with things like attention, feeling emotions such as fear, locating where the pain is, and so on. But the dorsal posterior insula seems to be specific to the actual 'hurt level' of pain itself.'


'We were able to find this area by developing a new method of tracking brain activity, based on a technique called arterial spin labelling. This allowed us to look at more complex brain states that stretch over much longer periods. By tracking pain felt over many hours, we were able to filter out more momentary experiences, such as variations in attention or fear,' said Professor Tracey.


The research team tracked brain activity in 17 healthy volunteers who had a cream containing capsaicin (the active ingredient in chillies) applied onto their right leg, causing a burning sensation. The volunteers indicated how much this burning sensation hurt.


Once the pain sensation began to fade, the researchers ‘rekindled’ the sensation by putting a hot water bottle where the cream was applied. A few minutes later, they provided pain relief by switching to a cooling water bottle. The volunteers’ ratings of how much the pain hurt accordingly went up and then down.


Activity changes in the dorsal posterior insula tracked these changes in the volunteers’ ratings of pain.


The research team plans to verify these results by attempting to switch off this brain region in relevant patients suffering from intractable pain. The team hopes that changing activity in the dorsal posterior insula will help to treat pain where other methods have failed.


This finding could also help detect pain in people with limited communication abilities, such as those in a coma, small children and dementia patients.

To the guy writing in about AP History, I say take it. The extra writing is really beneficial not only for studying history, but also for college; and if he's applying to Europe, they don't give a fuck about bubble ins, and only want writing, so that's a plus too. Americans can be lazy about school, but it's detrimental in the long run. Definitely take it!

Also for AP World, u don't have to know that many specific dates, just general time periods that span a few centuries. The writing isn't that bad, there's three essays on the test and like 70 questions multiple choice. It's a great class, I loved it!

Re: babob, the more writing you do the better. Go for the AP, get some college credit so you can spend that time in university with an elective. Writing well and communicating ideas effectively and clearly are very valuable skills, and you only get better at it by grinding through assignment after assignment.

March 14th 1879: Einstein born


On this day in 1879, the German physicist Albert Einstein was born in Ulm. Despite now being acclaimed as a genius the young Einstein struggled in school, especially dealing with a speech impediment. However he still had a great passion for science, and this interest was encouraged by his Polish tutor, leading him to write his first paper aged sixteen. He went on to study in Zurich, Switzerland, where he met his future first wife Mileva Maric. He had a bad reputation at university, and earned such a poor reference from one of his professors that he struggled to get a job after graduation. In 1905, he published a series of scientific papers, one of which detailed his famous mass-energy equivalence formula - E = mc2. These papers were initially neglected by physicists, but after the endorsement of eminent scientist Max Planck, Einstein’s standing rose in the science community. In 1915, Einstein completed his most famous work - the general theory of relativity. He received the 1921 Nobel Prize in Physics, but not for the relativity theory. Some of his later work included the groundbreaking idea that the universe is not static but in fact constantly expanding. Einstein became a U.S. citizen in 1940, after moving there upon Adolf Hitler’s rise to power in Germany when Einstein became a target of their anti-Semitic policies. He became involved in anti-nuclear arms and equal rights movements. Albert Einstein died in April 1955 aged 76 in Princeton, New Jersey, and is still hailed as one of the greatest scientists in history.

It’s Pi Day tomorrow! A very special Pi Day, because on March 14, 2015, at 53 seconds past 9:26 AM the date and time will spell out the first 9 decimal digits of the constant π. I’ll be celebrating by eating pie.


This GIF is a visual representation of C = 2r*π (the relationship between the circumference and the diameter).


*These smart folks have pretty much convinced me that Tau (τ=2π=6.2831…) is actually a better constant. And on Tau Day (June 28th), I get to eat TWO pies. But we have to wait until 2031 to get those extra decimal digits for τ.

Invasive Cancer Incidence and Survival — United States,...





Invasive Cancer Incidence and Survival — United States, 2011 Invasive Cancer Incidence and Survival — United States, 2011


In the United States, about two of three persons diagnosed with cancer survive ≥5 years after diagnosis. This depends on the type of cancer and age at diagnosis, and was lower among black persons compared with white persons. Differences in survival after cancer diagnosis might be attributable to differences in type of cancer, stage at diagnosis, timeliness of follow-up after diagnosis, appropriate treatment after diagnosis, or having a chronic condition.


Among persons with cancer diagnosed during 2003–2010, the 5-year relative survival rate was 65%. This percentage was similar for males and females. The 5-year relative survival was highest among those diagnosed with cancer before age 45 years (81%) and decreased with increasing age. Among the most common cancer sites, 5-year relative survival was highest for prostate cancer (97%) and breast cancer (88%), intermediate for colorectal cancer (63%), and lowest for lung cancer (18%). The 5-year relative survival after any cancer diagnosis was lower for black persons (60%) than for white persons (65%) and for each cancer site.

For the AP World History question-- I took AP European History, and it is a really difficult class, so if you struggle with having a lot of reading and writing and remembering dates and such, it might not be for you. I loved it, though. I thought it was fascinating. The writing is very specific timed essays, tailored to the AP test. Some of them are document-based, so you actually have evidence to back up what you're saying. Tl;dr, if you love history, take AP!!

Thanks for the answer! I hope babob4312 sees this :)
