Stolen truck carrying radioactive material found in Mexico
AP: Authorities say a missing shipment of radioactive material was found near where the stolen truck transporting the cobalt-60 was abandoned in central Mexico.
The highly radioactive material had been removed from its container, officials said, and one predicted that anyone involved in opening the box could be in grave danger of dying within days.
The cobalt-60 was left in a rural area about a kilometer (a half a mile) from Hueypoxtla, an agricultural town of about 4,000 people, but it posed no threat or a need for an evacuation, said Juan Eibenschutz, director general of the National Commission of Nuclear Safety and Safeguards.
The truck was stolen from a gas station in Hidalgo, which is about 24 miles from where the material was found.

A 21 year old guy had worn a pair of contact lenses during a barbecue party.(An event or meal at which food is cooked outdoors over an open grill or fire)
While barbecuing he stared at the fire charcoals continuously for 2-3 minutes.
After a few minutes, he started to scream for help and moved rapidly, jumping up and down.
No one in the party knew why he was doing this?
Then he admitted into the Hospital, the doctor said he’ll be blind permanently because of the contact lenses that he had worn.
Contact lenses are made by plastics, and the heat from the charcoal melted his contact lenses.
DO NOT WEAR CONTACT LENSES WHERE OVERHEATING AND FLAMES ARE CONCERNED…. OR WHILE COOKING…!
Spread this around because this sounds terrible as fuck!
SHIT YEAH THIS IS IMPORTANT SO SPREAD THE WORD PLEASE
I’m gonna go ahead and stop this right here.
This is bullshit.
Most contact lenses anymore are made of silicone, and anyone who has ever baked muffins in a silicone pan at 425F knows that these things don’t melt.
The non-silicone ones are hydrophilic and…
You know what. Just google it. Or snopes it.
Suffice is to say, if the heat would melt your contacts, it would boil your eyeballs first.

What Gives Summer That Distinct Smell?
As summer approaches us of the southern hemisphere we look forward to the sunny afternoons, the days at the beach and the smell of freshly mown grass - but what is that smell and why is it so relaxing?
When grass is cut, fats and phospholipids are broken down into long chain fatty acids, eg. linoelic acid, these fatty acids are then oxidised and chopped up by enzymes to form an end product that is either a six or twelve carbon chain. The six carbon chain molecule is the one responsible for the smell of grass so we shall focus on it. The molecules have a carbonyl group on the end and a double bond three carbons in from the end, and thus using some high school chemistry we can determine that the name of the organic molecule is cis-3-hexanal. Our noses are fantastic tools for discovering molecules and are particularly good at detecting this one; humans can detect cis-3-hexanal at 0.25 parts per billion. Cis-3-hexanal is very unstable and quickly mutates from a cis to trans - a molecule which is known as trans-2-hexanal. This molecule is known as the ‘leaf aldehyde’ and in part of what makes up commercial odours as ‘green odour’.
Cis-3-hexanal plays a role in many other aspects of life other than the smell of freshly mown grass - is it also important in the smell of strawberries, in the recovery of plants when they are damaged by pests and surprisingly in medicine. Studies have shown that molecules very similar to cis-3-hexanal can have a positive healing effect on the psychological damage caused by stress by activating blood flow in the primary olfactory cortex. So, maybe next time you’re having a rough day, go mow the lawn and spend some time sun bathing on your freshly trimmed grass.
How dare this be on my dashboard as winter approacheth!!
Let us dream hexanal dreams, though.
I hate this smell.
I love summer and warmth and green grass and trees more than life itself.
And I hate this smell.
Microscopic image of spirochetes which are the organism that cause Lyme disease.
Published: Thursday, March 21, 2013 - 21:05 in Biology & Nature
Scientists have confirmed that the pathogen that causes Lyme Disease — unlike any other known organism — can exist without iron, a metal that all other life needs to make proteins and enzymes. Instead of iron, the bacteria substitute manganese to make an essential enzyme, thus eluding immune system defenses that protect the body by starving pathogens of iron. To cause disease, Borrelia burgdorferi requires unusually high levels of manganese, scientists at Johns Hopkins University (JHU), Woods Hole Oceanographic Institution (WHOI), and the University of Texas reported. Their study, published March 22, 2013, in The Journal of Biological Chemistry, may explain some mysteries about why Lyme Disease is slow-growing and hard to detect and treat. The findings also open the door to search for new therapies to thwart the bacterium by targeting manganese.

Debunking The Largest Void in The Universe
Discovered in 2007, this is the largest known void in the universe. More info: http://bit.ly/17CJxaA
Decided to give this reply its own post since I saw people taking off what I said about this pic:
This is extremely false and misleading. If I’m not mistaken (please correct me if I’m wrong), this is actually Barnard 68. B68 is a dark nebula:
"Barnard 68 is a molecular cloud, dark absorption nebula or Bok globule, towards the southern constellation Ophiuchus and well within our own galaxy at a distance of about 500 light-years, so close that not a single star can be seen between it and the Sun. American astronomer Edward Emerson Barnard added this nebula to his catalog of dark nebulae in 1919. He published his catalog in 1927, at which stage it included some 350 objects. Because of its opacity, its interior is extremely cold, its temperature being about 16 K (−257 °C). Its mass is about twice that of the Sun and it measures about half a light-year across." [source]
It’s actually a blob of dust gravitationally collapsing in on its own mass to eventually become a star in like 100,000 years.
This is simply a photoshopped version, whoever did this must have used the liquify tool to give the nebula’s figure a slightly different shape. But what caught my attention aside from that suspicious description about being “completely empty of normal matter and dark matter” was the fact that I remember what the brighter stars surrounding B68 look like.
This is B68:
See how similar it looks? down to the position of the closer stars most visible? The above pic is a sham :/ I love the mysteries of the Universe as much as the next person but there’s really no point in misleading stuff like this. Oh and p.s. the link provided above in the original post is a completely different article talking about a completely different occurrence unrelated to the provided image of B68.
Carl Sagan and the Dalai Lama found deep connections in [1991-92] meetings, says Sagan’s widow
Religion and science do not have to be at odds. Science, said Ann Druyan, widow of Cornell astronomer Carl Sagan, can communicate with, learn from and even benefit from religion and vice versa.
Druyan, a writer and media producer who collaborated with Sagan for 19 years until his death in 1996, reflected on dialogues in the early 1990s between Sagan and the Dalai Lama at a Sept. 28 lecture in Anabel Taylor Auditorium. For the first time, film excerpts of the meeting between the two were shown in a public venue.
Sagan, Cornell professor and author of “Cosmos,” “Contact” and “Dragons of Eden,” among other books, was perhaps best known for his extraordinary ability to communicate science to the public. “He wanted to share with everyone the wonder and awe that science inspired in him,” Druyan said.
She stressed that there were political motivations behind Sagan’s work as well: “Carl believed that you can’t have a democratic society if you have a tiny scientific elite and a public who is uncomfortable with the methods and language of science,” she said.
Sagan entered the public eye in the 1960s — a time rife with changes in both culture and thought. The Catholic church had just switched from giving masses in Latin to local languages so that everyone could understand them, and Druyan said Sagan was trying to do the same for science.
The Dalai Lama, who has had a lifelong interest in science, first met with Sagan during a visit to Ithaca in 1991. Their discussion continued in India the following year, where the Dalai Lama cleared his calendar to spend a full day talking with Sagan and Druyan.

On Sept. 28 at Cornell, Ann Druyan, writer and media producer and widow of the late Carl Sagan, reflected on conversations Sagan had with the Dalai Lama on science and religion in the early 1990s.
In the short segment shown of their conversations, Sagan asked the Dalai Lama about his beliefs in God and what he as a Buddhist would do if a discovery in science conflicted with Buddhist doctrine. The Dalai Lama replied that even Buddha was said to question his teachings and that Buddhists rely on doctrine as “findings” rather than as “scripture.”
"If through thorough investigation things become clear, only then is it time to accept and believe," he said.
"So is there no conceivable scientific finding that would make you no longer consider yourself a Buddhist?" Sagan responded.
The Dalai Lama said there would be no point at which his spirituality and his respect for science would come at such odds with each other. “Buddhism is not so much a religion, but a ‘science of the mind’ or an ‘inner science’ … there is much benefit to learning from [scientists’] findings,” he explained.
Regarding the contributions of religion to science, Druyan said that while science has developed an amazing library of facts, it does not have the human social organization and the ability to inspire that religion has. That’s why we have lost that magical excitement with space exploration that the world once shared, she said.
What science needs are more ambassadors. “We don’t have a Carl Sagan right now,” she said — a well-informed, ethical and passionate leader, versed in the arts and sciences, concerned about the planet yet willing to “get into any kind of trouble for the sake of the human future.”
Druyan’s lecture was one of many events on campus prefacing the Dalai Lama’s Oct. 9 visit to Cornell. Many of the ideas she discussed are put forth in Sagan’s latest book, “The Varieties of Scientific Experience: A Personal View of the Search for God,” which she edited.

Actually energy is matter too. And vice-versa.
Because, you know. This:
Which also means that mc2=E.
Except that I’m on my phone and I can’t square the speed of light. Or anything for that matter (womp womp). So pretend like I’m smart enough to make proper exponential notation from a phone.
