"Studies show that if you've served in the military -- any branch, any war, or even if you served in a time of peace -- you have a much higher risk of dying from amyotrophic lateral sclerosis, or ALS (Lou Gehrig's disease) than if you were not in the military. And no one seems to know why." [more inside]
Seven fossilized brains from the Cambrian. A complex animal skeleton from the pre-Cambrian. Oxygen made by photosynthesis a billion years before the Great Oxygenation Event. Carbon made by life from 4.1 billion years ago. (Okay, maybe not so fast on that last one.)
Sapiens: A Brief History of Humankind by Yuval Noah Harari - "The book delivers on its madly ambitious subtitle by in fact managing to cover key moments in the developmental history of humankind from the emergence of Homo Sapiens to today's developments in genetic engineering." Also btw, check out Harari on the myths we need to survive, re: fact/value distinctions and their interrelationships.
One of the most distinctive masks worn during the Carnival of Venice is “Il Medico della Peste,” or “The Plague Doctor.” But the distinctive bone-white mask and black clothing was actually the 17th century equivalent of a biocontainment suit. Albeit one based on very shaky science.
The word algebra stems from the Arabic word al-jabr, which has its roots in the title of a 9th century manuscript written by the mathematician Al-Khwarizmi. The Kitab al-mukhtasar fi hisab al-jabr wal-muqabala (The Compendious Book on Calculation by Completion and Balancing) was a pioneering piece of work - offering practical answers for land distribution, rules on inheritance and distributing salaries. This treatise also underpins the science of flight and the engineering behind the fastest car in the world. via
Lamar Smith continues waging his three-year war on the National Science Foundation. If Congress has its way, the next round of grants by the National Science Foundation, a hallmark of government funding for graduate students and scientists, will no longer be based on scientific merit. Proposals would not be reviewed by panels of preeminent scholars across the United States as they have been for more than a half-century; instead, they would all be “in the national interest,” with strict new rules adopted earlier this month by a Republican House committee. Previously. This is not the first time Smith has tried to impose Congressional control on the NSF's budget.
“Cut Microbe” is a sculpture entirely hand cut out of paper. Measuring 44 inches/112cms in length, it is half a million times bigger than the ecoli bacteria upon which it is based. I wanted to create a sculpture that reflected in the process of being made the incredible scale and complexity of this microbiological world. I am amazed at the strange beauty of the natural world and wanted to open people’s eyes to aspects of it that they rarely see. -Rogan Brown

Nima Arkani-Hamed is championing a campaign to build the world's largest particle collider - "Two years ago, he agreed to become the inaugural director of the new Center for Future High Energy Physics in Beijing. He has since visited China 18 times, campaigning for the construction of a machine of unprecedented scale: a circular particle collider up to 60 miles in circumference, or nearly four times as big around as Europe's Large Hadron Collider (LHC). Nicknamed the 'Great Collider', and estimated to cost roughly $10 billion over 30 years, it would succeed the LHC as the new center of the physics universe. According to Arkani-Hamed and those who agree with him, this 100-trillion-electron-volt (TeV) collider would slam subatomic particles together hard enough to either find the particles that the LHC could not muster or rule them out, rescuing or killing the naturalness principle and propelling physicists toward one of two radically different pictures: that of a knowable universe, or an unknowable multiverse."

Earlier this month, Youyou Tu was awarded the Nobel Prize in medicine for her discovery of artemisinin, also known as qinghaosu. She is the first Chinese Nobel recipient for work that was done in mainland China. Dr. Tu's studies were done in the midst of the Cultural Revolution, a politically precarious time for Chinese academics, which adds a layer of historical complexity to her work. It is difficult to overstate the importance of artemisinin to anti-malarial efforts. Unfortunately, artemisinin-resistant strains of malaria are already beginning to appear only thirty years after the drug was introduced.
What's the Difference Between Data Science and Statistics? — Not long ago, the term "data science" meant nothing to most people-even to those who worked with data. A likely response to the term was: "Isn't that just statistics?" These days, data science is hot. The Harvard Business Review called data scientist the "Sexiest Job of the 21st Century." So what changed? Why did data science become a distinct term? And what distinguishes data science from statistics?
The Runner’s High: It’s Like Smoking Weed [High Times]
Research on mice [Proceedings of the National Academy of Sciences] has confirmed that a “runner’s high” arises from a release of anandamide, a neurotransmitter that stimulates the same cannabinoid receptors that cannabis does. If you have ever run, biked, lifted weights, or performed any kind of physical exercise, you may have noticed a sense of euphoria and the feeling you are relieved of physical pain and anxiety. They thought it came from β-endorphin, but now scientists have confirmed that anandamide is most likely the cause.[more inside]
The world's coral is suddenly and rapidly starting to die - "This is only the third time we've seen what we would refer to as a global bleaching event. [The prior events] were in 1998 and 2010, and those were pretty much one year events. We're looking at a similar spatial scale of bleaching across the globe, but spanning across at least 2 years. So that means a lot of these corals are being put under really prolonged stress, or are being hit 2 years in a row."

RED 4K Video of Colorful Liquid in Space. "Once again, astronauts on the International Space Station dissolved an effervescent tablet in a floating ball of water, and captured images using a camera capable of recording four times the resolution of normal high-definition cameras. The higher resolution images and higher frame rate videos can reveal more information when used on science investigations, giving researchers a valuable new tool aboard the space station. This footage is one of the first of its kind. The cameras are being evaluated for capturing science data and vehicle operations by engineers at NASA's Marshall Space Flight Center in Huntsville, Alabama." [Via]
A controversial talk by Tuck Ngun at the ongoing American Society of Human Genetics 2015 meeting in Baltimore presented evidence of epigenetic mechanisms associated with homosexuality in discordant male twins (i.e., one gay, the other straight). The conference organizers and news outlets quickly trumpeted that scientists had discovered epigenetic markers capable of predicting the sexual orientation of a male; however, the reaction of scientists at the meeting was less enthusiastic. Ed Yong at the Atlantic wrote a particularly thorough takedown. Criticisms centered around the small sample size (37 pairs of twins), the fact that the samples were taken from saliva (whereas you'd expect epigenetic variants influencing sexuality to occur in the brain), and the fact that the predictive model they developed was not terribly predictive (67% accuracy).

It's well understood that many species of parasitic wasp, when they lay their eggs on host caterpillars, also inject viruses that prevent the host's immune system from attacking the eggs. But it was recently discovered that some of those virus genes, as well as genes from parasitic wasps themselves, have become a part of the genome of some lepidopteran species (even protecting these species from a different type of virus), thus demonstrating horizontal gene transfer between insect species (link to paper).
“Head trainer Teri Turner Bolton presses her palms together over her head, the signal to innovate, and then puts her fists together, the sign for “tandem.” Comparative psychologist Stan Kuczaj records several seconds of audible chirping between [the dolphins] Hector and Han, then his camera captures them both slowly rolling over in unison and flapping their tails three times simultaneously.

It’s important to remember that scientists present their data in ways that their fellow scientists can comprehend. Technical jargon and statistical error bars can efficiently communicate the legitimacy of a scientific breakthrough to a scientific audience. However, these same features can be both confusing and distracting when presented to a wider audience. For the public to be excited and informed about the latest scientific breakthroughs, technical data visualizations need to be transformed into engaging visual stories that a wider community can understand.
