writes "An article in The Register explains an experiment at Fermilab:
"How can we tell from the inside of our Universe if it’s actually real or just a hologram? Boffins at Fermilab have set out to answer this thorny question with a new experiment in the National Accelerator Lab called the Holometer."
"Scientists reckon it’s possible that, just like the pixels that make up the 3D image on your TV, all the information about the Universe could actually be encoded in tiny packets in just two dimensions. These natural pixels would be ten trillion trillion times smaller than an atom – a unit known as the Planck length. Things get heavily quantum from this assumption on"
(Note: I always get confused when things get "heavily quantum".)
"The Fermilab’s Holometer will attempt to measure the quantum jitter of space itself using a pair of interferometers placed close together. Each instrument will send a one-kilowatt laser beam at a beam splitter and down two perpendicular 40m arms. The light will then be reflected back to the splitter when the two beams recombine, creating fluctuations in the brightness if these vibrations exist."
(Sounds good so far...)
“If we find a noise we can’t get rid of, we might be detecting something fundamental about nature – a noise that is intrinsic to space-time,” said Fermilab physicist Aaron Chou, lead scientist and project manager for the Holometer. “It’s an exciting moment for physics. A positive result will open a whole new avenue of questioning about how space works.”

"Raising animals to eat produces more greenhouse gasses (via methane and nitrous oxide) than all of the carbon dioxide excreted by automobiles, boats, planes and trains in the world combined. "

writes ""New technologies for monitoring brain activity are generating unprecedented quantities of information. That data may hold new insights into how the brain works — but only if researchers can interpret it. To help make sense of the data, neuroscientists can now harness the power of distributed computing with Thunder, a library of tools developed at the Howard Hughes Medical Institute's Janelia Research Campus.
"Freeman chose to build on a new platform called Spark. Developed at the University of California, Berkeley's AMPLab, Spark is rapidly becoming a favored tool for large-scale computing across industry, Freeman says. Spark's capabilities for data caching eliminates the bottleneck of loading a complete data set for all but the initial step, making it well-suited for interactive, exploratory analysis, and for complex algorithms requiring repeated operations on the same data. And Spark's elegant and versatile application programming interfaces (APIs) help simplify development. Thunder uses the Python API, which Freeman hopes will make it particularly easy for others to adopt, given Python's increasing use in neuroscience and data science.
Researchers can find everything they need to begin using the open source library of tools at http://freeman-lab.github.io/t...
To make Spark suitable for analyzing a broad range of neuroscience data — information about connectivity and activity collected from different organisms and with different techniques — Freeman first developed standardized representations of data that were amenable to distributed computing. He then worked to express typical neuroscience workflows into the computational language of Spark.""Link to Original Source
writes "A special issue of Science magazine devoted to Vanishing Fauna publishes a series of articles about the man-caused extinction of species and the implications for ecosystems and the climate.
"During the Pleistocene epoch, only tens of thousands of years ago, our planet supported large, spectacular animals. Mammoths, terror birds, giant tortoises, and saber-toothed cats, as well as many less familiar species such as giant ground sloths (some of which reached 7 meters in height) and glyptodonts (which resembled car-sized armadillos), roamed freely. Since then, however, the number and diversity of animal species on Earth have consistently and steadily declined. Today we are left with a relatively depauperate fauna, and we continue to lose animal species to extinction rapidly. Although some debate persists, most of the evidence suggests that humans were responsible for extinction of this Pleistocene fauna, and we continue to drive animal extinctions today through the destruction of wild lands, consumption of animals as a resource or a luxury, and persecution of species we see as threats or competitors.

writes "Can bottom-up cap and trade work?
California has funded a $3.2 million system to burn methane from dairy cows in Wisconsin.
It's all part of California's "cap and trade" effort to reduce climate change.
"California’s program is the latest incarnation of an increasingly popular — and much debated — mechanism that has emerged as one of the primary weapons against global warming. From China to Norway, Kazakhstan to the Northeastern United States, governments are requiring industries to buy permits allowing them to emit set levels of greenhouse gases. Under these plans, the allowable levels of pollution are steadily reduced and the cost of permits rises, creating an economic incentive for companies to cut emissions."
“We might be witnessing the birth of a new system, without quite realizing it,” said Glen P. Peters, a climate researcher at the Center for International Climate and Environmental Research in Oslo. “When you think of all these bottom-up initiatives around the world, maybe we are living through the transformation right now.”
"Experts who support cap and trade contend that a market mechanism can reach more deeply into the economy than any other approach, changing the behavior even of people and companies that might not necessarily care about global warming.""Link to Original Source

The discovery of bugs in software used to run oil rigs, refineries and power plants has prompted a global push to patch the widely used control system. The bugs were found by security researchers and, if exploited, could give attackers remote access to control systems for the installations.

His reporting is definitely on the edge. "Mr. Krebs, 41, tries to write pieces that cannot be found elsewhere. His widely read cybersecurity blog, Krebs on Security, covers a particularly dark corner of the Internet: profit-seeking cybercriminals, many based in Eastern Europe, who make billions off pharmaceutical sales, malware, spam, frauds and heists like the recent ones that Mr. Krebs was first to uncover at Adobe, Target and Neiman Marcus."

writes "Each year, the British Medical Journal (BMJ) publishes a set of interesting articles which are, while scientifically correct, do not meet the usual criteria for publication (untraditional papers).
This highlight of this year's edition is one which found that 0.8% of US females reported virgin births. That is, they reported that they had never had intercourse and that they had been pregnant. It should be noted that they did not claim immaculate conception, they just reported (on regular surveys) that they had been pregnant and (in a separate section of the survey) had never had intercourse.
"The authors of "Like a virgin (mother)" — whose prose is devoid of irony — say such scientifically impossible claims show researchers must use care in interpreting self-reported behavior. Fallible memory, beliefs and wishes can cause people to err in what they tell scientists."
These results are from a large, well regarded, longitudinal study of women in the USA.
Some insight into these findings:
"Of those who said they became pregnant as virgins, 31 percent also said they had signed chastity pledges; 15 percent of nonvirgins who became pregnant said they had signed such pledges, in which a girl vows not to have sex until she marries."
"The ostensibly chaste mothers were also less likely to know how to use condoms, according to the report. " (duh... this could be a big clue here!)
Finally the authors also report (again, without irony) that: "The researchers found that although the mothers in question were more likely to have boys than girls, and to be pregnant during the weeks leading up to Christmas, neither similarity to the Virgin Mary was statistically significant."

When a patron is over the limit, the device identifies him by the RFID card in his pocket and tags the card. It also displays a warning above the urinal.

Apparently they don't prevent claiming the car but about 2/3 of patrons decide to take a cab.
