When DNLee was approached to write blog posts for Biology Online, she quite reasonably asked about the terms of the agreement. When she turned them down, their response was...somewhat less than reasonable. And when DNLee posted to her blog about it, Scientific American – who hosts her blog as part of their science blog network – responded in perhaps the most tone-deaf manner possible. [more inside]

In a not too distant future, societies of all countries come to rely on an intricate network of artificial intelligence devices designed to bring efficacy to man's life. Yet, man continues to devour himself in useless wars. A strong political hierarchy now divides all powers into three factions, and A.I. devices rapidly gain ground as efficiency becomes a priority. As social revolts grow worse everyday, authorities seek ways to control their citizens. They decide to carry out a series of tests that will determine not only whether some crucial powers can be transferred to non human entities, but also whether man is ready to yield those powers. The world has become a cell for all man and women, who withstand and endure their lives, rather than living them. Machines might have found a solution. From now on, you are set free. [more inside]
With 2000+ global studies confirming safety, GM foods among most analyzed "Environmental impact studies are predominant in the body of GM research, making up 68% of the 1,783 studies. These studies investigated environmental impact on the crop-level, farm-level and landscape-level. Nicolia and his team found “little to no evidence” that GM crops have a negative environmental impact on their surroundings." [more inside]
On 4 July, good news arrived in the inbox of Ocorrafoo Cobange, a biologist at the Wassee Institute of Medicine in Asmara. It was the official letter of acceptance for a paper he had submitted 2 months earlier to the Journal of Natural Pharmaceuticals, describing the anticancer properties of a chemical that Cobange had extracted from a lichen.
Last summer, researchers at Yale published a study proving that physicists, chemists and biologists are likely to view a young male scientist more favorably than a woman with the same qualifications. Presented with identical summaries of the accomplishments of two imaginary applicants, professors at six major research institutions were significantly more willing to offer the man a job. If they did hire the woman, they set her salary, on average, nearly $4,000 lower than the man’s. Surprisingly, female scientists were as biased as their male counterparts. A wonderful long article by Eileen Pollack where she talks to her former mentors, the study authors, and the other female science professors at her alma mater. NYTMagazine, worth reading especially for the absence of glib simple answers. (Previously, of course.)

Dean Martin used to make a joke in his stage shows: "I don't drink anymore. I freeze it and eat it like a Popsicle". But how exactly does that work? It's not exactly as simple as whipping up some Koolaid, poring it in a mold and sticking it in the freezer. And though summer is over and autumn is here, that's no reason not to indulge in a Tequila Lime Margarita Pop or a Havana Mojito Popsicle. And if you're feeling really daring, how about some Absinthe Pops?
When a liquid is dropped onto a smooth plate that is heated to a specific temperature well above its boiling point, boiled vapor will get trapped underneath the remainder of the droplet insulating it from the hot plate, allowing it to dance around the plate like oil on a wet surface in what is known as the Leidenfrost effect. Intriguingly, surfaces that are grooved into the shape of a saw blade will cause droplets suspended by the Leidenfrost effect to predictably skitter in the direction of the groove, allowing University of Bath undergraduate students Carmen Cheng and Matthew Guy to build a fascinating maze.

In March 2012, inspectors from the U.S. Department of Agriculture uncovered a problem in Elgin, Texas. Beef sausage from a small family-run meat processor appeared to have been contaminated with a nasty bacterium called Listeria monocytogenes. The bug can make people sick and, in rare cases, be deadly. The processor had to recall more than a ton of sausage. It’s the kind of story that strikes terror in the hearts of other sausage peddlers, including Mike Satzow, so he uses phages to keep his small company's sausages safe to eat.

We tend to think now of scurvy as mainly a punch line, if anything—“scurvy-ridden rats” is the kind of popular pirate epithet that appears in even the most G-rated family fare. Partly this is because now, fully understanding its mechanism, it seems a particularly ridiculous problem. But ask anyone who's suffered from it: it is a singularly horrid and terrible way to die.- The Spoil of Mariners, Colin Dickey, Lapham's Quarterly.

Revelations in the field of quantum physics have resulted in the discovery of the Amplituhedron, a jewel-like higher dimensional object whose volume elegantly predicts fundamental physical processes that took the brilliant Dr. Richard Feynman hundreds of pages of abstruse mathematics to describe. The theoretical manifold not only enables simple pen-and-paper calculation of physics that would normally require supercomputers to work out, but also challenges basic assumptions about the nature of reality -- forgoing the core concepts of locality and unitarity and suggesting that space and time are merely emergent properties of a timeless, infinitely-sided "master amplituhedron," whose geometry represents the sum total of all physical interactions.

X inactivation is a type of gene dosage compensation. In humans, the sex chromosomes X and Y determine the sex of an individual - females have two X chromosomes (XX), males have one X and one Y chromosome (XY). All of the genes on the Y chromosome are required in male development, while the genes on the X chromosome are needed for both male and female development. Because females receive two X chromosomes, they inherit two copies of many of the genes that are needed for normal function. Extra copies of genes or chromosomes can affect normal development. An example is Down's syndrome, which is caused by an extra copy of part or all of chromosome 21. In female mammals, a process called X inactivation has evolved to compensate for the extra X chromosome. In X inactivation, each cell 'switches off' one of its X chromosomes, chosen at random, to ensure the correct number of genes are expressed, and to prevent abnormal development.

How often does a great story dominate the headlines, only to be dropped from the news cycle? How often do journalists tell us of a looming danger or important discovery – only to move quickly to the next new thing? What really happened? How did these events change us? And what are the lingering consequences that may affect our society to this day? These are the questions we are answering at Retro Report, an innovative documentary news organization launched in 2013 as a timely online counterweight to today’s 24/7 news cycle. Combining documentary techniques with shoe-leather reporting, we peel back the layers of some of the most perplexing news stories of our past with the goal of encouraging the public to think more critically about current events and the media in ~10 minute segments.

[Pinker] conflates scientific knowledge with knowledge as such. In his view, anybody who has studied any phenomena that are studied by science has been a scientist...If they were interested in the mind, then they were early versions of brain scientists. If they investigated human nature, then they were social psychologists or behavioral economists avant la lettre. Leon Wieseltier pens a response to Steven Pinker's essay on scientism, both in the pages of the New Republic. Others, including some prominent atheists, have taken issue with Pinker as well.
Did you hear that a group of 400 angry farmers attacked and destroyed a field trial of genetically modified rice in the Philippines this month? That, it turns out, was a lie.

Massive earthquakes in Chile and Japan have been found to cause the dramatic increase in violent quakes around fracking's largely unregulated wastewater injection wells observed in the Midwest in the past two years, where injected water acts as a lubricant for geological faults that were previously thought to be "dead" or stable for millions of years.
This 1,600-Year-Old Goblet Shows that the Romans Were Nanotechnology Pioneers. The Lycurgus Cup appears opaque green under normal light, but the ancient dichroic glass vessel transforms to a translucent red color when lit from behind.
