I've often found that, when I can't understand a concept in science or math, putting it into pictures will make everything make more sense. It's like magic. Now, none of the visualizations I used as a kid involved a cadre of trained golden retrievers, but maybe that's a flaw the Kansas school system needs to correct.

Parents, romantic partners and roommates of America: I am not encouraging your child, partner or person you share living space with to do this. At least, not in your good microwave. They should buy their own for this sort of thing. And for the love of Pete, they should wear protective eye covering.

I am so very serious about the protective eye coverings.

As a little kid, I used to think electrical substations would make really awesome jungle gyms. This video helpfully demonstrates why 5-year-old Maggie was an idiot.

This is the Eldorado Substation near Boulder City, Nevada. What you're seeing: A substation like this one is connected to long-distance transmission lines and electricity has to be very high voltage to travel on those. The substation "steps up" the voltage so the electricity can travel. Everything at a substation is hot, in that shock the bejeezus out of you sense. So that maintenance can be done, substations are built with switching functions that allow you to disconnect and reconnect various parts of the system in modular sort of way. The big, crazy spark in this video happened when some of the switching mechanisms failed. The Arcs 'n Sparks page at Stoneridge Engineering explains what happened next...

Gregory Glass is a disease ecologist -- he studies the relationship between pathogens and hosts. A professor at Johns Hopkins Bloomberg School of Public Health, Glass's laboratory is Baltimore's urban underbelly, where he hangs out with beefy sewer rats. Apparently, Baltimore is a hotbed of rat research. I wonder if Glass has encountered any Rat Kings. From Smithsonian:

Glass has been following the secret lives of wild Norway rats – otherwise known as brown rats, wharf rats, or, most evocatively, sewer rats -- for more than two decades now, but Baltimore has been a national hotspot for rat studies for well over half a century. The research push began during World War II, when thousands of troops in the South Pacific came down with the rat-carried tsutsugamushi disease, and the Allies also feared that the Germans and Japanese would release rats to spread the plague...

Glass – who started off studying cotton rats in the Midwest – traps the animals with peanut butter baits and monitors the diseases they carry. (Hantavirus, once known as Korean hemorrhagic fever, and leptospirosis – which can cause liver and kidney failure – are of particular concern.) Lately he’s been interested in cat-rat interactions. Cats, he and his colleagues have noticed, are rather ineffectual rat assassins: they catch mainly medium-sized rodents, when they catch any at all. This predation pattern may actually have adverse effects on human health: some of the deceased mid-sized rats are already immune to harmful diseases, while the bumper crops of babies that replace them are all vulnerable to infection. Thus a higher proportion of the population ends up actively carrying the diseases at any given time.

A gorgeously glowing meteor flew over Utah on Wednesday night, alarming some citizens and delighting others. The image above is from a security camera at the IMFT plant in Lehi, Utah. From KSL-TV, were you can also see some video of the fireball:

Clark Planetarium Director Seth Jarvis said the stony meteorite was probably traveling 80,000 miles an hour when it hit our atmosphere. He said it happened 100 miles up in the air; so despite the brightness, Utah was never in any danger. "These collisions can do damage, but they are extremely rare; and literally once in a century do you observe something that's actually doing damage," he said. Witness Andy Bailey said, "Oh, it lit up the whole sky, like almost brighter than the day. It was bright." Don White was in Wyoming and told KSL Newsradio for a moment he suspected a nuclear strike. "With something that brilliant and that fast, it was like, whoa, did we just get hit or something? It would have been some bigger noise I guess if a nuclear device had gone off," he said.

The South Fore people of Papua New Guinea used to eat their dead relatives' brains as a sign of respect, passing on the deadly prion disease kuru--a relative of mad cow disease--in the process. But long before the Fore stopped the tradition on the advice of scientists in the 1950s, evolution was already at work. Less than 200 years ago, according to New Scientist, a member of the Fore was born with a gene mutation that protected against kuru. They passed it to their children.

Because having the mutation helped you live longer (and, thus, have more children), it quickly spread through the Fore population. Today, several Fore families descended from people who took part in the brain-eating rituals owe their existence to the reality of evolution.

Edinburgh University engineers have a plan to use genetically engineered bacteria that glow in the presence of explosives to detect landmines. The project is student-led, overseen by Alistair Elfick.

The bugs can be mixed into a colourless solution, which forms green patches when sprayed onto ground where mines are buried.

Edinburgh University said the microbes could be dropped by air onto danger areas.

Within a few hours, they would indicate where the explosives can be found.

The scientists produced the bacteria using a new technique called BioBricking, which manipulates packages of DNA.

It's actually quite pretty (again, relatively speaking), but this slug is most likely an Arion rufus, a species that's native to Europe, but has been found in British Columbia and is apparently now also at large in Ontario. Hermaphroditic in nature, some slugs can even knock themselves up, so it only takes a single invader to build an army. Once the population is established, the slugs become (and I quote) the "slow moving lions of the vegetable world."

So how do you get rid of them? The story offers two possibilities. First, you can leave out beer for the slugs. They're attracted to fermented yeast, but they're a little dumb and they can't swim, so they'll end up crawling in and drowning themselves. The other option: Collect the slugs when they come out at night and "immerse them in boiling water." The article, unfortunately, does not mention whether you can then eat Arion rufus in a nice butter sauce.

Homo floresiensis was a kind of adorably tiny human being that lived on the island of Flores up until 18,000 years ago. Nature says "These astonishing little people, nicknamed 'hobbits', made tools, hunted tiny elephants and lived at the same time as modern humans who were colonizing the area."

There has been some debate as to whether or not the Flores Man was just descendants of Homo Sapiens "dwarfed by disease." But that debate has been settled, according to researchers from Stony Brook University Medical Center in New York who claim Homo floresiensis is a "genuine ancient human species."

Using statistical analysis on skeletal remains of a well-preserved female specimen, researchers determined the "hobbit" to be a distinct species and not a genetically flawed version of modern humans. Details of the study appear in the December issue of Significance, the magazine of the Royal Statistical Society, published by Wiley-Blackwell.

In 2003 Australian and Indonesian scientists discovered small-bodied, small-brained, hominin (human-like) fossils on the remote island of Flores in the Indonesian archipelago. This discovery of a new human species called Homo floresiensis has spawned much debate with some researchers claiming that the small creatures are really modern humans whose tiny head and brain are the result of a medical condition called microcephaly.

An article in The American Journal of Forensic Medical Pathology entitled "Use of a pig model to demonstrate vulnerability of major neck vessels to inflicted trauma from common household items" describes all the ways you can stab people with stuff you're allowed to take through airport security, like pens and plastic knives.

Commonly available items including a ball point pen, a plastic knife, a broken wine bottle, and a broken wine glass were used to inflict stab and incised wounds to the necks of 3 previously euthanized Large White pigs. With relative ease, these items could be inserted into the necks of the pigs next to the jugular veins and carotid arteries. Despite precautions against the carrying of metal objects such as knives and nail files on board domestic and international flights, objects are still available within aircraft cabins that could be used to inflict serious and potentially life-threatening injuries. If airport and aircraft security measures are to be consistently applied, then consideration should be given to removing items such as glass bottles and glass drinking vessels. However, given the results of a relatively uncomplicated modification of a plastic knife, it may not be possible to remove all dangerous objects from aircraft. Security systems may therefore need to focus on measures such as increased surveillance of passenger behavior, rather than on attempting to eliminate every object that may serve as a potential weapon.

Last year, he created a massive metal protein sculpture linked to Leonardo's Vitruvian Man. Now, Julian has made 30 objects inspired by his former physics research area of quantum physics. The objects are currently on display at the American Center for Physics in College Park, Maryland. More images and background on the work after the jump.

The Lung Flute is a simple device that uses sound waves to vibrate wads of mucus in your chest cavity until they rip apart and become more easily cough-up-able. (For better or for worse, the ultimate "results" of using the Flute are not shown in the above video.) Handy, certainly. But why, you may be wondering, would such a thing end up on Popular Science's list of The Best Innovations of 2009? Easy. It's because you and your common cold are not the primary audience for a Lung Flute concerto.

The idea for the horn came one night in 1985. Hawkins, an acoustics engineer, and his colleagues began brainstorming how they could use sound to mess with various bodily functions. They joked about what frequency a toilet would need to vibrate at to force an uncontrollable bowel movement and, slightly more seriously, a way to dislodge goo in sick people's lungs. Months later, Hawkins was reminded of that discussion when he learned that chronic obstructive pulmonary disease (COPD), a group of lung diseases that includes emphysema and chronic bronchitis, makes breathing tough for 10 million people, and causes 127,000 deaths in the U.S. every year. "It's the number-four cause of death in the U.S.," he says. "I thought, 'Yeah, I should do something about this.' "

Today, doctors in Japan use the $40 Lung Flute as a tool to collect sputum from patients suspected of carrying tuberculosis, and in Europe and Canada it's used to help test phlegm for lung cancer. Clinical trials in the U.S. have shown that it is at least as effective as current COPD treatments. At press time, Hawkins expected the device to receive FDA approval any day, and says the reusable device could also provide home relief for patients with cystic fibrosis, influenza and asthma.

"When I say there is no water crisis, you must be wondering, 'Is this guy talking to his hat?'" That's how Asit Biswas led off his speech last month at the 2009 Nobel Conference. And--oddly worded idiom aside--he was right. That's exactly what everyone was thinking.

The Conference--really a lecture series timed to coincide with the distribution of Nobel Prizes--brings Nobel winners and eminent researchers from around the world to Gustavus Adolphus College in St. Peter, Minnesota. All the lectures orbit a central theme. This year, it was water. Or, rather, the lack of water. Most of the speakers talked about the risk of losing this important resource--how we humans threaten our own water supply, how that puts us at risk for a whole mess of trouble, and how we might be able to tackle the global water crisis.

But that crisis is a myth, according to Biswas. He's the president of the Third World Centre for Water Management and winner of the 2006 Stockholm Water Prize, and he says that there's plenty of water to go around. Freaking out about water supply is pointless, he says. Worse, it wastes time and resources that could be used to fix the world's real problem--actually getting the water to the people.

To find out more about why Biswas thinks global institutions like the United Nations and the World Bank are dead wrong on water, I called him for a post-Nobel Conference interview.

Sometimes, from certain places, the light from the sun can briefly appear green. NASA's Astronomy Picture of the Day explains,

Just as the setting Sun disappears completely from view, a last glimmer appears startlingly green. The effect is typically visible only from locations with a low, distant horizon, and lasts just a few seconds. A green flash is also visible for a rising Sun, but takes better timing to spot. A dramatic green flash was caught in the above photograph in 1992 from Finland. The Sun itself does not turn partly green, the effect is caused by layers of the Earth's atmosphere acting like a prism.

The Times Labs blog takes a hard look at the data on music sales and live performances and concludes that while the labels' profits might be falling, artists are taking in more money, thanks to the booming growth of live shows. The Times says that they'd like more granular data about who's making all the money from concerts -- is there a category of act that's a real winner here? -- but the trend seems clear. The 21st century music scene is the best world ever for some musicians and music-industry businesses, and the worst for others. Which raises the question: is it really copyright law's job to make sure that last years winners keep on winning? Or is it enough to ensure that there will always be winners?

Why live revenues have grown so stridently is beyond the scope of this article, but our data - compiled from a PRS for Music report and the BPI - make two things clear: one, that the growth in live revenue shows no signs of slowing and two, that live is by far and away the most lucrative section of industry revenue for artists themselves, because they retain such a big percentage of the money from ticket sales.

(It's often claimed that live revenues are only/mostly benefitting so-called 'heritage acts'. Unfortunately, the data doesn't shed any light on this because live revenues are not broken down by type of act, gig size or ticket price.)..

It's interesting too that, overall, industry revenues have grown in the period - though admittedly not by much - which arguably adds strength to the notion that, when the BPI releases its annual report claiming how much 'the music industry' has suffered from the growth in illegal file-sharing, what it perhaps should be saying is how much the record labels have suffered.

Wow, it's apparently Debunking 2012 Day here on BoingBoing. I honestly had no idea that David had his Mark Dery post in the works. But it does segue nicely into what I had planned. The Information is Beautiful blog put together an infographic that explains--in a short and quick format---what the 2012 believers are claiming, and why those claims are (lets just say it) stupid.

Great example of how the believers get this stuff wrong: The "facts" on the believer side of the graph are pulled directly from believer Web sites. When David from IIB sent me the original version of the graphic, I noticed that the believers had managed to misspell the name of Yale archaeologist Michael D. Coe, calling him "Michael D. Cole". They were also claiming that he was one of them. I don't have Coe's email, but I do have John Hoopes'. He's an archaeologist who has spent his life studying the ancient Maya and other ancient Central and South American civilizations...and my former professor when I was an anthropology undergrad at the University of Kansas. I contacted Hoopes to see what he knew about that claim and, according to him, it's way off. Coe, Hoopes says, does believe that 2012 would have been an important date to the ancient Maya*, and probably one they would have celebrated. But "important" like, say, Christmas is important to us. Or New Years Eve 1999/2000. Not "important" as in "the world is going to end."

*Specifying "ancient Maya" here, because we're not talking about the beliefs and culture of the very-much-alive Maya people. Just like modern Egyptian belief and culture is different from (but connected to and influenced by) that of the ancient Egyptians, so go the Maya. Coe is not speaking on behalf of the Maya here, he's just talking about what he thinks their ancestors might have believed.

Anyone who's watched "Jurassic Park" (and, subsequently, thought up a velociraptor escape plan) knows there were meat-eating dinosaurs. Anyone who's had to talk a child (or themselves) down from a post-"Jurassic Park" nightmare knows that most dinosaurs ate plants. But Pbryden's 4-year-old wants to know whether any dinosaurs ate both.

That sounds like just the kind of thing velociraptors would do to trick you into complacency...

Here's the Guardian's Alison Flood's detailed look at Kim Stanley Robinson's latest novel, Galileo's Dream, a fictionalized biography of Galileo that features time-travel.

What he came up with was three different temporal dimensions - the first moving very fast, at the speed of light, the second very slow and "vibrating slowly back and forth, as if the universe itself were a single string or bubble", the third - antichronos - in reverse. We experience them as one, creating a three-way interference pattern, which accounts for sensations such as foresight, déjà vu, nostalgia and precognition. The compound nature of time, Robinson writes, "creates our perception of both transience and permanence, of being and becoming". He's shown the novel to people who are "much more serious about the time travel stuff" and they're "having a blast". "They immediately map my three strands of time onto their system. They think I've partially discovered the real thing," he says gleefully...

So Galileo makes his telescope. He sees the Seven Sisters constellation, surrounded by "thickets of lesser stars, granulated almost to white dust in places ... No one else in the history of the world had ever seen these stars, until this very night, this very moment". He discovers Jupiter's four moons. He studies acceleration and motion. He observes sunspots. He frequently, frequently rings "like a struck bell" as his genius strikes: "Here it was, the truth of the situation - the cosmos revealed in a single stroke as being one way rather than another. The Earth was spinning under his feet, also rolling around the sun ... Again he rang like a bell. His flesh buzzed like struck bronze, his hair stood on end. How things worked; it had to be; and he rang." He stamps on the ground after he is tried by the Inquisition for supporting Copernicanism: "'It still moves!' he said. 'Eppur si muove!'"

A study in the scientific journal Brain and Cognition suggests that increasing the "crosstalk" between the brain's left and right hemispheres can increase creativity. Researchers from the Richard Stockton College of New Jersey ran an experiment on 62 people to gauge creative thinking. After a first try at the task, some of the participants were told to shift their eyes horizontally back and forth for 30 seconds, an exercise that boosts the communication between the hemispheres. Those subjects performed much better on the test the second time around than a control group who stared straight ahead. The scientists published the results of their study in the journal Brain and Cognition. From the British Psychological Society Research Digest:

An important factor that the researchers took note of was the participants' handedness. Prior research has suggested that people who have one hand that is particularly dominant, so-called "strong-handers", have less cross-talk between their brain hemispheres compared with people who are more ambidextrous or "mixed handed"...

The key finding is that on their second creativity attempt, strong-handers who'd performed the horizontal eye movements subsequently showed a significant improvement in their creativity, in terms of being more original (i.e. suggesting ideas not proposed by others) and coming up with more categories of use...

The researchers also showed that, for strong-handers, the beneficial effects of the eye movement exercise lasted nine minutes for originality, but just three to six minutes in terms of coming up with more categories of use.

We've posted before about the Pope's chief astronomer Rev. Jose Gabriel Funes and his statements on possible extraterrestrial life. (ETs "don't contradict our faith," he has said.) The Vatican recently hosted a conference on the topic of astrobiology -- the study of life in the universe -- where a group of international scientists from a variety of fields discussed the possibility of alien life. From the Associated Press:

Funes said the possibility of alien life raises "many philosophical and theological implications" but added that the gathering was mainly focused on the scientific perspective and how different disciplines can be used to explore the issue.

Chris Impey, an astronomy professor at the University of Arizona, said it was appropriate that the Vatican would host such a meeting.

"Both science and religion posit life as a special outcome of a vast and mostly inhospitable universe," he told a news conference Tuesday. "There is a rich middle ground for dialogue between the practitioners of astrobiology and those who seek to understand the meaning of our existence in a biological universe..."

The Church of Rome's views have shifted radically through the centuries since Italian philosopher Giordano Bruno was burned at the stake as a heretic in 1600 for speculating, among other ideas, that other worlds could be inhabited.

A BBC story (and film) talks about the problems virologists and public health defenders face as they tackle a virus like H1N1 flu and try to figure out how the disease will impact people around the globe. It's an honest examination of both the strengths of science, and the barriers that exist around human knowledge.

Such are the limitations of science, whether meteorology or virology. The recent H1N1 or swine flu predictions have led to forecasts of 65,000 deaths in the UK - but the truth is, we simply don't know. Yet in reporting the outbreak, the media broadly falls between two extremes - from alarming scare stories to experts who purport mass vaccination to be "madness, foolhardy and a gamble". Whatever happens when the pandemic pans out, there will be a substantial third group - the "I told you so" faction. Pandemic disease remains a critical test of the extent of what we do and don't know.

Researchers have grown replacement penis tissue for rabbits from the animals' own cells. The erectile tissue was then implanted and the rabbits apparently went on to screw like rabbits, successfully reproducing. According to the scientists at Wake Forest University Baptist Medical Center, this was the "most complete replacement of functional penile erectile tissue reported to date." Someday, the technique could help human patients who require penile reconstruction due to abnormalities, cancer, or injury. It might even be used to treat extreme cases of erectile dysfunction. The research was led by tissue engineering pioneer Dr. Anthony Atala, who I posted about in 2006 for his success engineering an artificial bladder that has since helped more than two dozen patients. From the Medical Center:

The scientists first harvested smooth muscle cells and endothelial cells, the same type of cells that line blood vessels, from the animals’ erectile tissue. These cells were multiplied in the laboratory. Using a two-step process, the cells were injected into a three-dimensional scaffold that provided support while the cells developed. As early as one month after implanting the scaffold in the animal’s penis, organized tissue with vessel structures began to form.

The cells were injected into scaffolds on two separate days, enabling them to hold almost six times as many smooth muscle cells as in the previous studies – which the scientists believe was a key to success. During an erection, it is the relaxation of smooth muscle tissue that allows an influx of blood into the penis. The relaxation is triggered by the release of nitric oxide from endothelial cells...

Functional testing of the implanted tissue showed that vessel pressure within the erectile tissue was normal, that blood flowed smoothly through it, that the response to nitric oxide-induced relaxation was normal as early as one month after implantation, and that veins drained normally after erection.

2,500 years ago, an army of 50,000 men left an oasis in western Egypt and were never heard from again. Now, archaeologists think they may have uncovered the missing troops, who were probably killed in a sandstorm.

...the team decided to investigate Bedouin stories about thousands of white bones that would have emerged decades ago during particular wind conditions in a nearby area. Indeed, they found a mass grave with hundreds of bleached bones and skulls. "We learned that the remains had been exposed by tomb robbers and that a beautiful sword which was found among the bones was sold to American tourists," Castiglioni said.

And now, unless popular film and novels have lied to us all, every last one of those skeletons will struggle to its feet and--enraged at the disruption of a centuries' long slumber--visit destruction upon archaeologist and Bedouin alike.

A man runs. He falls down. He struggles back onto his feet and he runs some more. It's a simple narrative. Even without much detail, you can understand what's going on. Pause the video, though, and the scene isn't nearly as clear. Movement makes up for the lack of other visual information. Your brain can read and understand a video at much lower resolution than it would need to make equal sense of a still frame.
