"Armed with Science," is a new science-focused TV show developed by two of the Department of Defense's in-house research laboratories and the Pentagon. They have always developed some crazy tech work, like perception tests on their robots. If Skynet is going to be real, I think these are the agencies that will put the terminators online.
Finite time blowup for an averaged three-dimensional Navier-Stokes equation - "[Terence Tao] has shown that in an alternative abstract universe closely related to the one described by the Navier-Stokes equations, it is possible for a body of fluid to form a sort of computer, which can build a self-replicating fluid robot that, like the Cat in the Hat, keeps transferring its energy to smaller and smaller copies of itself until the fluid 'blows up.'

Monsanto Is Going Organic in a Quest for the Perfect Veggie - "The lettuce, peppers, and broccoli—plus a melon and an onion, with a watermelon soon to follow—aren't genetically modified at all. Monsanto created all these veggies using good old-fashioned crossbreeding, the same technology that farmers have been using to optimize crops for millennia. That doesn't mean they are low tech, exactly. Stark's division is drawing on Monsanto's accumulated scientific know-how to create vegetables that have all the advantages of genetically modified organisms without any of the Frankenfoods ick factor."

Do the Apollo flags remain where they were planted or have they fallen or have they disintegrated after four decades of intense UV and heat? James Fincannon investigates flags left behind from Apollo 11, 12, 14, 15, 16, and 17 missions.
Network Theory Overview - "The idea: nature and the world of human technology are full of networks! People like to draw diagrams of networks. Mathematical physicists know that in principle these diagrams can be understood using category theory. But why should physicists have all the fun? This is the century of understanding living systems and adapting to life on a finite planet. Math isn't the main thing we need, but it's got to be part of the solution... so one thing we should do is develop a unified and powerful theory of networks." (via ;)

The next day his arm was amputated due to Acute Compartment Syndrome. He recounts his experience with as much humor and grace as one can muster.
PLOS’ New Data Policy: Public Access to Data "PLOS has always required that authors make their data available to other academic researchers who wish to replicate, reanalyze, or build upon the findings published in our journals. In an effort to increase access to this data, we are now revising our data-sharing policy for all PLOS journals: authors must make all data publicly available, without restriction, immediately upon publication of the article. Beginning March 3rd, 2014, all authors who submit to a PLOS journal will be asked to provide a Data Availability Statement, describing where and how others can access each dataset that underlies the findings." Openscience.org also have a primer on why open science data is important.
Watch out for tongue splinters. Deep sea scientist Craig McClain is investigating communities which thrive on wood that falls to the bottom of the sea, so he "chunked 36 logs overboard". You want to see footage of the experiment set to dubstep? Course you do. [via mefi projects]
A Star in a Bottle. "An audacious plan to create a new energy source could save the planet from catastrophe. But time is running out."
Approximately 176 million women and girls worldwide suffer from endometriosis; 8.5 million in North America alone. Associated costs of the disease are estimated to be a staggering $22 billion annually. The pain can be debilitating and infertility is a common outcome. Yet after decades of research, the jury is still out on what causes it, and many doctors still don't even know when they should be looking for it. Now, a group of researchers at MIT have taken a new approach, one with a characteristic engineering slant.
Here are some links to online galleries that combine science, medicine, and art in some way. (previously: psychiatry and art)
P values, the 'gold standard' of statistical validity, are not as reliable as many scientists assume.
Open warfare erupts in the world of mathematical biology, as Lior Pachter of UC-Berkeley writes three blog posts attacking two papers in Nature Bioscience, accusing one of them of being "dishonest and fraudulent": The Network Nonsense of Albert-Laszlo Barabasi, The Network Nonsense of Manolo Kellis, and Why I Read the Network Nonsense Papers. Kellis (MIT) and his co-authors respond (.pdf.)
In his 1996 book The Song of the Dodo, David Quammen observed that if you destroy most of a habitat and leave only a small patch of wilderness behind, you have effectively created an island—and islands, for complex ecological reasons, sustain far fewer species and far more extinctions than mainlands. Now watch things get complicated. At the same time that our logging, mining, farming, road-building, suburban-sprawling species is turning the entire planet into an archipelago, “global trade and travel do the reverse: they deny even the remotest islands their remoteness.” The result, as Kathryn Schulz reports, is that we are living through The Sixth Extinction.
Bill Nye is debating the head of the Creation Museum tomorrow.

From I Fucking Love Science: "In a paper posted online this week Professor Stephen Hawking claimed that black holes do not exist - at least, not as we currently understand them. He claims that the traditional notion of a black hole's "event horizon" from which nothing can escape, even light, is incompatible with quantum physics. If so, physicists will have to redefine black holes entirely." [more inside]

"Given the desire for ambitious scientists to break from the pack with a striking new finding, Dr. Ioannidis reasoned, many hypotheses already start with a high chance of being wrong. Otherwise proving them right would not be so difficult and surprising — and supportive of a scientist’s career. Taking into account the human tendency to see what we want to see, unconscious bias is inevitable. Without any ill intent, a scientist may be nudged toward interpreting the data so it supports the hypothesis, even if just barely." [more inside]
"In October 2013, Drs. Tim Perkins and Abby van Den Berg of the University of Vermont’s Proctor Maple Research Center, revealed the findings of a study at a maple syrup conference in New Brunswick, Canada that sent waves through the industry. In 2010, they were studying vacuum systems in sap collection operations. Based on the observation that one of the mature trees in the study that was missing most of its top was still yielding high volumes of sap, they hypothesized that the maples were possibly drawing moisture from the soil and not the crown. Previously, they had presumed that the sap dripping from tap holes was coming from the upper portion of the tree. But, if the tree was missing most of its crown then, they surmised, it must be drawing moisture from the roots. ... They realized that their discovery meant sugarmakers could use saplings, densely planted in open fields, to harvest sap. In other words, it is possible that maple syrup could now be produced as a row crop like every other commercial crop in North America." [more inside]
Gender Swap - Experiment with The Machine to be Another. "Gender Swap is an experiment that uses The Machine to be Another system as a platform for embodiment experience (a neuroscience technique in which users can feel themselves like if they were in a different body). In order to create the brain illusion we use the immersive Head Mounted Display Oculus Rift, and first-person cameras. To create this perception, both users have to syncronize their movements. If one does not correspond to the movement of the other, the embodiment experience does not work. It means that both users have to constantly agree on every movement they make. Throughout this experiment, we aim to investigate issues like Gender Identity, Queer Theory, feminist technoscience, Intimacy and Mutual Respect." [NSFW, Via]
