Keep Your Fingers Crossed: How Superstition Improves Performance: New research shows that having some kind of lucky token can actually improve your performance — by increasing your self-confidence. …Volunteers who had their lucky charm did better at a memory game on the computer, and other tests showed that this difference was because they felt more confident. They also set higher goals for themselves. Just wishing someone good luck — with “I press the thumbs for you,” the German version of crossing your fingers — improved volunteers’ success at a task that required manual dexterity.

~Of course, this is still a form of delusion. Everyone tested in the study was superstitious and had a lucky charm. I’d like to see a study or two that involved people who don’t rely on superstition as well. I think if a person understands the delusion of superstition, they will therefore not need the “lucky” feather in their cap. They will have appropriate self-confidence based on their actual abilities. Still, it’s an interesting study.

More Than Half the World’s Population Gets Insufficient Vitamin D, Says Biochemist: Half the people in North America and Western Europe get insufficient amounts of vitamin D. “Elsewhere, it is worse, given that two-thirds of the people are vitamin D-insufficient or deficient. It is clear that merely eating vitamin D-rich foods is not adequate to solve the problem for most adults.” Currently, the recommended daily intake of vitamin D is 200 international units (IU) for people up to 50 years old; 400 IU for people 51 to 70 years old; and 600 IU for people over 70 years old.
“There is a wide consensus among scientists that the relative daily intake of vitamin D should be increased to 2,000 to 4,000 IU for most adults,” Norman says. “A 2000 IU daily intake can be achieved by a combination of sunshine, food, supplements, and possibly even limited tanning exposure.” While there is now abundant data on vitamin D and its benefits, Norman believes there is room for more study.
Because vitamin D is found in very few foods naturally (e.g. fish, eggs and cod liver oil) other foods such as milk, orange juice, some yogurts and some breakfast foods are fortified with it. The fortification levels aim at about 400 IU per day.

Low Vitamin D Levels Associated With Cognitive Decline: An estimated 40 percent to 100 percent of older adults in the United States and Europe are deficient in vitamin D, according to background information in the article. This deficiency has been linked to fractures, various chronic diseases and death. Vitamin D may help prevent the degeneration of brain tissue by having a role in formation of nervous tissue, maintaining levels of calcium in the body, or clearing of beta-amyloid, the substance that forms the brain plaques and tangles associated with Alzheimer’s disease.
Editorial: “Vitamin D has been known for many years to play a critical role in skeletal health. More recently, observational studies have reported inverse associations between levels of serum 25-hydroxyvitamin D, the metabolite that best reflects overall vitamin D status, and the risk of a wide range of disease, including cancer, vascular disease, infectious conditions, autoimmune diseases, osteoporosis, type 2 diabetes mellitus and obesity. …It is now time to test the various hypotheses generated by observational studies of vitamin D in adequately designed and conducted randomized controlled trials.”

Team Develops Non-Toxic Oil Recovery Agent: A team of chemists has developed a non-toxic, recyclable agent that can solidify oil on salt water so that it can be scooped up like the fat that forms on the top of a pot of chilled chicken soup. The agent could potentially be used to recover oil lost in the British Petroleum (BP) spill in the Gulf of Mexico. The gelling agent developed by his team is environmentally benign. It uses a sugar-based molecule that can be obtained from renewable sources and is biodegradable. In addition, only a relatively small amount of the agent — five percent of the volume of the oil being recovered — is required for the process, which handles a range of oil from crude to vegetable oil, to work.

Smoking Mind Over Smoking Matter: Surprising New Study Shows Cigarette Cravings Result from Habit, Not Addiction: The new study found that the intensity of cravings for cigarettes had more to do with the psychosocial element of smoking than with the physiological effects of nicotine as an addictive chemical. …Dr. Dar’s studies conclude that nicotine is not addictive as physiological addictions are usually defined. While nicotine does have a physiological role in increasing cognitive abilities such as attention and memory, it’s not an addictive substance like heroin, which creates true systemic and biologically-based withdrawal symptoms in the body of the user, he says. Dr. Dar believes that people who smoke do so for short-term benefits like oral gratification, sensory pleasure and social camaraderie. Once the habit is established, people continue to smoke in response to cues and in situations that become associated with smoking. Dr. Dar believes that understanding smoking as a habit, not an addiction, will facilitate treatment. Smoking cessation techniques should emphasize the psychological and behavioral aspects of the habit and not the biological aspects, he suggests.

Light and Moderate Physical Activity Reduces the Risk of Early Death: A new study has found that even light or moderate intensity physical activity, such as walking or cycling, can substantially reduce the risk of early death. the largest health benefits from light or moderate activity (such as walking and cycling) were in people who do hardly any physical activity at all. Although more activity is better — the benefits of even a small amount of physical activity are very large in the least physically active.
The good news from this study is that you don’t have to be an exercise freak to benefit from physical activity. Just achieving the recommended levels of physical activity (equivalent to 30 minutes daily of moderate intensity activity on 5 days a week) reduces the risk of death by 19%, while 7 hours per week of moderate activity (compared with no activity) reduces the risk of death by 24%. “This research confirms that is not just exercising hard that is good for you but even moderate everyday activities, like walking and cycling, can have major health benefits. Just walking to the shops or walking the children to school can lengthen your life — as well as bringing other benefits for well-being and the environment.”

New Antibacterial Material for Bandages, Food Packaging, Shoes: A new form of paper with the built-in ability to fight disease-causing bacteria could have applications that range from anti-bacterial bandages to food packaging that keeps food fresher longer to shoes that ward off foot odor. …They made sheets of paper from graphene oxide, and then tried to grow bacteria and human cells on top. Bacteria were unable to grow on the paper, and it had little adverse effect on human cells.

A Blood Test for Depression? Researchers evaluated blood gene expression profiles in healthy individuals and patients diagnosed with major depressive disorder, or MDD. They identified a set of seven genes in whole blood that was able to distinguish un-medicated MDD patients from healthy controls. “This is a first, but major step in providing a molecular diagnostic tool for depression.” Although psychiatry already has specific criteria for diagnosing mental health disorders, this type of diagnosis would be unbiased and particularly valuable for those with whom it is more difficult to have a conversation. It may also eventually assist in reducing the stigma associated with mental health problems.

3-D Gesture-Based Interaction System Unveiled: Scientists have developed the next generation non-contact gesture and finger recognition system. The novel system detects hand and finger positions in real-time and translates these into appropriate interaction commands. Furthermore, the system does not require special gloves or markers and is capable of supporting multiple users. This system detects multiple fingers and hands at the same time and allows the user to interact with objects on a display. The users move their hands and fingers in the air and the system automatically recognizes and interprets the gestures accordingly.
Cinemagoers will remember the science-fiction thriller Minority Report from 2002 which starred Tom Cruise. In this film Tom Cruise is in a 3-D software arena and is able to interact with numerous programs at unimaginable speed, however the system used special gloves and only three fingers from each hand.
The FIT prototype provides the next generation of gesture-based interaction far in advance of the Minority Report system. The FIT prototype tracks the user’s hand in front of a 3-D camera. The 3-D camera uses the time of flight principle, in this approach each pixel is tracked and the length of time it takes light to be filmed travelling to and from the tracked object is determined. This allows for the calculation of the distance between the camera and the tracked object.
“A special image analysis algorithm was developed which filters out the positions of the hands and fingers. This is achieved in real-time through the use of intelligent filtering of the incoming data. The raw data can be viewed as a kind of 3-D mountain landscape, with the peak regions representing the hands or fingers.” In addition plausibility criteria are used, these are based around: the size of a hand, finger length and the potential coordinates.
A user study was conducted and found that the system both easy to use and fun. However, work remains to be done on removing elements which confuses the system, for example reflections caused by wristwatches and palms which are positioned orthogonal to the camera.
“With Microsoft announcing Project Natal, it is likely that similar techniques will very soon become standard across the gaming industry. This technology also opens up the potential for new solutions in the range of other application domains, such as the exploration of complex simulation data and for new forms of learning.”

Why am I talking about nanotech on Darwin’s birthday? If you think about it, without evolution, we wouldn’t be able to manipulate our world so deftly and with such finesse. About 195,000 years ago homo sapiens first appeared in the fossil record. We started leaving Africa about 70,000 years ago, and migrated as far as the Americas 14,500 years ago.

A mere 10,000 years ago, we were mostly hunter-gatherers in nomadic groups. The first proto-states were developed only 6,000 years ago. Think of that! Look how far we’ve come in such a short time!

Think of how we lived just 100 years ago in 1910.

• By 1910 many suburban homes were wired up with power and new electronic gadgets.
• Vacuum cleaners and washing machines had just become commercially available, though still expensive for middle class folks
• The telephone was new, and millions of American homes were connected by manual switchboard
• People relied on the paper for their news, but radio technology was in its infancy
• The age of the airship was in full swing. Only 7 years previously, the Wright brothers had flown at Kitty Hawk
• Henry Ford introduced the Model T 2 years before and sold about 10,000 of them this year
• Advances in the use of gases meant the first electric refrigerators and air conditioning units.
• Neon lighting was debuted in Paris
• Inventions included: escalators, teabags, cellophane, instant coffee and disposable razor blades
• Women still had another 3 years of corsets

Things they didn’t have in 1910:

• stainless steel
• zippers
• the modern bra
• the modern band-aid
• the pop-up toaster
• sliced bread

But let’s get back to Liquid Glass. You spray it on. It’s transparent, non-toxic and can protect virtually any surface against almost any damage from hazards such as water, UV radiation, dirt, heat and bacterial infections. It’s flexible and breathable, which means it can be used on all kinds of products.

The liquid glass spray (technically termed “SiO2 ultra-thin layering”) consists of almost pure silicon dioxide (silica, the normal compound in glass) extracted from quartz sand. Water or ethanol is added, depending on the type of surface to be coated. There are no additives, and the nano-scale glass coating bonds to the surface because of the quantum forces involved. According to the manufacturers, liquid glass has a long-lasting antibacterial effect because microbes landing on the surface cannot divide or replicate easily.

Liquid glass was invented in Turkey and the patent is held by Nanopool, a family-owned German company. Research on the product was carried out at the Saarbrücken Institute for New Materials. Nanopool is already in negotiations in the UK with a number of companies and with the National Health Service, with a view to its widespread adoption.

The liquid glass spray produces a water-resistant coating only around 100 nanometers (15-30 molecules) thick. On this nanoscale the glass is highly flexible and breathable. The coating is environmentally harmless and non-toxic, and easy to clean using only water or a simple wipe with a damp cloth. It repels bacteria, water and dirt, and resists heat, UV light and even acids. UK project manager with Nanopool, Neil McClelland, said soon almost every product you purchase will be coated with liquid glass.

Food processing companies in Germany have already carried out trials of the spray, and found sterile surfaces that usually needed to be cleaned with strong bleach to keep them sterile needed only a hot water rinse if they were coated with liquid glass. The levels of sterility were higher for the glass-coated surfaces, and the surfaces remained sterile for months.

Other organizations, such as a train company and a hotel chain in the UK, and a hamburger chain in Germany, are also testing liquid glass for a wide range of uses. A year-long trial of the spray in a Lancashire hospital also produced “very promising” results for a range of applications including coatings for equipment, medical implants, catheters, sutures and bandages. The war graves association in the UK is investigating using the spray to treat stone monuments and grave stones, since trials have shown the coating protects against weathering and graffiti. Trials in Turkey are testing the product on monuments such as the Ataturk Mausoleum in Ankara.

The liquid glass coating is breathable, which means it can be used on plants and seeds. Trials in vineyards have found spraying vines increases their resistance to fungal diseases, while other tests have shown sprayed seeds germinate and grow faster than untreated seeds, and coated wood is not attacked by termites. Other vineyard applications include coating corks with liquid glass to prevent “corking” and contamination of wine. The spray cannot be seen by the naked eye, which means it could also be used to treat clothing and other materials to make them stain-resistant. McClelland said you can “pour a bottle of wine over an expensive silk shirt and it will come right off”.

In the home, spray-on glass would eliminate the need for scrubbing and make most cleaning products obsolete. Since it is available in both water-based and alcohol-based solutions, it can be used in the oven, in bathrooms, tiles, sinks, and almost every other surface in the home, and one spray is said to last a year.

Liquid glass spray is perhaps the most important nanotechnology product to emerge to date. It will be available in DIY stores in Britain soon, with prices starting at around £5 ($8 US). Other outlets, such as many supermarkets, may be unwilling to stock the products because they make enormous profits from cleaning products that need to be replaced regularly, and liquid glass would make virtually all of them obsolete.

Thanks, PhysOrg

A bit more info on it:

The flexible and breathable glass coating is approximately 100 nanometres thick (500 times thinner than a human hair), and so it is completely undetectable. It is food safe, environmentally friendly (winner of the Green Apple Award) and it can be applied to almost any surface within seconds . When coated, all surfaces become easy to clean and anti-microbially protected (Winner of the NHS Smart Solutions Award ). Houses, cars, ovens, wedding dress or any other protected surface become stain resistant and can be easily cleaned with water ; no cleaning chemicals are required. Amazingly a 30 second DIY application to a sink unit will last for a year or years, depending on how often it is used. But it does not stop there – the coatings are now also recognised as being suitable for agricultural and in-vivo application. Vines coated with SiO2 don’t suffer from mildew, and coated seeds grow more rapidly without the need for anti-fungal chemicals. This will result in farmers in enjoying massively increased yields.

…The really clever part is that there are no added nano-particles , resins or additives- the coatings form and bond due to quantum forces. Our research informs us that in all probability, we offer the most versatile coating in the world. This technology is now available for domestic use in Germany. Full scale retail availability in the UK will commence in early 2010.

Here’s some information from PBS:

After some three and a half billion years of life’s evolution on this planet – and after almost two million years since people recognizable as human first walked its surface – a new human burst upon the scene, apparently unannounced.

It was us.

Until then our ancestors had shared the planet with other human species. But soon there was only us, possessors of something that gave us unprecedented power over our environment and everything else alive. That something was – is – the Human Spark.

What is the nature of human uniqueness? Where did the Human Spark ignite, and when? And perhaps most tantalizingly, why?

In a three-part series broadcast on PBS in January 2010, Alan Alda takes these questions personally, visiting with dozens of scientists on three continents, and participating directly in many experiments – including the detailed examination of his own brain.

Program One: Becoming Us (link goes to full video)
Alan Alda confronts the puzzle of why our ancestors in Africa got the Spark and evolved into us, while the first humans to leave Africa for Europe–the Neanderthals–never did. Why did we flourish, while they changed very little for thousands of generations before eventually dying out?

Program Two: So Human, So Chimp (link goes to full video)
Alan Alda joins researchers studying human children and chimpanzees to discover why we share some skills with our closest living relatives, but have far surpassed them in our most uniquely human capabilities. Though we both descend from a common ancestor and are genetically so similar, why are we worlds apart in our behaviors and abilities?

Program Three: Brain Matters (link goes to full video)
Peer into Alan Alda’s head to find out which parts of our brain are responsible for our most human characteristics. Where do tool use and language reside? And how do our brains allow us to understand symbolism, figure out what others are thinking, and even travel in time? Are insight and imagination what really make humans unique?

Steve Mirsky interviews Alan Alda in two parts for Science Talk, the podcast for Scientific American. You can download or listen to them here. This is how I found out about the series and realized that Alan Alda isn’t just an actor. I had no idea he was into science so much.

Alan Alda’s Human Spark, Interview 1: Alan Alda, star of stage, screen and science, talks with podcast host Steve Mirsky about his new PBS science series The Human Spark as well as his strong interest in science and long association with Scientific American.

Interview Part 2: Alan Alda, host of the new PBS science series The Human Spark, talks to podcast host Steve Mirsky about his experiences as a fictional physican, a real patient and an amateur scientist.

Anyhoo, this is a roundup post in which I cover several topics that are tenuously connected at best. Here’s what I’m rambling on about:

• I’m a citizen scientist now! WOOT!
  • Encyclopedia of Life!
  • My Flickr
• Moving the body affects how we think – a study
• Prayer and meditation may reshape the brain – a study

First, I want to talk about a ScienceDaily report: Massive Online ‘Macroscopic Observatory’ Of Earth’s Biodiversity To Be Created. “Wanted (soon): observations from environment-minded citizens that will allow science to study biodiversity at a planetary level in a massive, comprehensive virtual observatory of historic importance.”

This guy, Edward O. Wilson, created a website, Encyclopedia of Life (eol). His dream: “Imagine an electronic page for each species of organism on Earth…” and they are starting to do just that. A page for every species. If you read the ScienceDaily article, it will be amazing. You’ll be able to get information from the Deep Web from images, maps, classification, common and scientific names, links to research and papers, etc.

It’s already there now, and growing all the time. In the future you’ll also be able to get genome sequences and much much more. Basically anything you want to know about a species will be there, at your fingertips, all on one page, for free. My scientific geekiness is giggling with delight!

And here’s where I get to finally call myself a scientist! Uh, well, a citizen scientist, which is still cool. eol wants people to submit their pictures. I’m a photographer, and I love taking pictures of nature, but I’ve never been able to do much with them. Now I can help with this project! Can you say WOOT!? I can. Woot WOOT! (Sorry, uber-geek moment there).

So what you do, what I did, was to open a Flickr account. I’m ZeNeeceC on Flickr now. I got some older pictures posted yesterday. Then here’s the tough part. You need to machine tag them with their scientific names. This is so that when you send them to the eol Flickr group, eol’s computer can get those images and put them on the right pages.

My friend Jeff said that eol sounded like a Wikipedia kind of thing for science. In a way, he’s right, because we get to contribute our images. But eol is serious about science, so the images will get authenticated. Until that time, they have a yellow box around them so people can see that they are contributed but might not be scientifically accurate like the rest of the info on the page.

Even further, though, if you just want high end science info, eol lets you set that up so that you don’t even see the citizen science stuff. It’s a very well done site.

Anyway, I am having trouble finding out what things are called. Flickr has a group called ID Please, which I joined. And I joined BugGuide.net  as ZeNeece to help me ID bugs. But the flowers and plants, I will need to find an online source to identify those more readily.

So that’s that. I wanted to share it with you because it’s so exciting to me, but also in case you or someone you know might be interested as well.

Onto some studies!

Our Bodies, Our Brains: a recent study shows that moving your body in certain ways can improve your ability to think. Published in Psychological Science.

Working with 38 subjects, the scientists confirmed that either a step forward (a typically positive movement) or a step backward (usually negative) significantly changed one’s ability to perform a mental task.

Taking four steps back improved a subject’s accuracy and timing on the task, whereas taking four steps forward led to longer processing times and more errors.

How cool is that? Now, if you follow the link, you’ll see that this was on 60 second science on Scientific American, so there are no links to studies. But they list the publication, Psychological Science, if you want to look into it further.

Prayer May Reshape Your Brain… And Your Reality: This is interesting. I’ve told you about some studies (see below) in the past in this field, which this article calls “neurotheology”.  The article from NPR is about Andrew Newberg, a neuroscientist at University of Pennsylvania who has written several books and studies very religious people and their brains. Newberg says: “The more you focus on something — whether that’s math or auto racing or football or God — the more that becomes your reality, the more it becomes written into the neural connections of your brain.”

He also tested a doctor who meditates for an hour a day. He had him meditate in a brain scanner.

As expected, his frontal lobes lit up on the screen: Meditation is sheer concentration, after all. But what fascinated Newberg was that Baime’s parietal lobes went dark. Newberg said, “This is an area that normally takes our sensory information, tries to create for us a sense of ourselves and orient that self in the world,” he explains. “When people lose their sense of self, feel a sense of oneness, a blurring of the boundary between self and other, we have found decreases in activity in that area.”

The article goes on to suggest that you can benefit from meditation and prayer as well, even if you don’t devote 1 or 2 hours a day to it. I find this interesting and compelling, and it goes along with the other studies listed below. I would have liked some studies referenced and linked to in the article, but I guess I’m not that lucky.

Here are the other posts I’ve done about other relevant brain and mind studies recently:

• Church: No brain activity required- study showed how experiencing transcendence basically shut down the right parietal lobe.
• More differences in the brains of believers and non-believers: A recent study that found religious people were less anxious about mistakes they made than non-believers.
• Knowledge and Beliefs are stored differently in the brain: this wasn’t a specific study. Dr. Steven Novella mentioned it in passing on his podcast.
• Religion is the path of least resistance: This was about an article in New Scientist where people are born believers. I strongly suspect the way they conducted the studies mentioned.
• Superstitious? It could be your lack of control: This was a neat study about people who were basically put into a situation where they felt a lack of control found patterns more readily in random information.

Charles Darwin celebrated his 200th birthday February 12 of this year. So of course many of the science podcasts I listen to, as well as many of the science and skeptic sites I visit, have been talking about evolution and Darwin and all that good stuff. Evolution is often paraphrased as the term, survival of the fittest, which is inaccurate. Here is how Dictionary.com defines it, as well as some other terms, just so we’re all on the same page:

• Survival of the Fittest
  a 19th-century concept of human society, inspired by the principle of natural selection, postulating that those who are eliminated in the struggle for existence are the unfit.
• Natural Selection
  n. The process in nature by which, according to Darwin’s theory of evolution, only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations while those less adapted tend to be eliminated.
• Evolution
  Biology. change in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift.

I’ve been slowly forming some random thoughts regarding the human population and evolution and I thought I’d write them down. Your input would be most welcome, as usual.

I heard on The Naked Scientists ( podcast number or which exact one, I’m not sure) recently that humans aren’t really evolving and haven’t for the last couple of thousand years or so. Chris, the Naked Scientist, was talking about something else so it was one of those explanations for something else, not the topic of conversation. So he didn’t go into detail.

My ears perked up though because I’ve been vaguely wondering about human evolution in the past several thousand years. Mainly because humans seem to do things backwards from the rest of nature. Or we seem to do that lately in our history.

For instance, we take care of the old and sick, to the point that otherwise frail and less than hearty people are able to reproduce, and to reproduce much longer into older age than ever before. This is when a woman’s eggs may have more genetic defects in them. Which is why women who are pregnant over a certain age are encouraged to get tested for genetic defects more than younger women are.

I have an aunt who was born with a serious birth defect – spina bifida. She needed countless surgeries over her childhood, and several in her adulthood as well. She ended up getting married and having a child, which even a hundred years ago would not have been possible.

There are huge differences in child mortality and survival throughout the world even today, based on availability of medical care, basic nutrition and other factors. But even 100 years ago the infant mortality rate was higher, right? What was it 2,000 years ago when medical care was rudimentary at best?

So what does this do to the gene pool and to human evolution?

I was talking to my friend Jeff about this yesterday and he made a comment that we are evolving, just with machines now. But I would suggest that’s not the same thing. It certainly doesn’t fall into the biological definition of evolution. I’m not saying that we aren’t evolving at all. But we seem to have stalled at least. Instead of natural selection within the human race, we have technology of all different sorts to compensate for whatever lack of genetic strength we may have.

This could be as simple as red headed people living in the Mediterranean. They don’t need to get sunburned and get skin cancer because they can wear sunblock and protective clothing and stay indoors more. Or a child can be born with asthma, something that would have shortened her life long ago, perhaps. Instead while she may take medication and change her lifestyle a bit, she can grow up to have children, who may also be prone to asthma.

Did you see that movie, Idiocracy? I didn’t watch it because, well, it looked really dumb. But the concept is interesting and is something I see in my life nowadays, to a small degree. The premise of the movie, from what I gathered, is that smart people stop having children so only stupid people have kids, giving birth to dumber and dumber people, until everyone is idiotic. I don’t know about that idea. Because both my husband and I are way smarter than our parents. But I do see people who can barely function in society having kids while smart people make the decision to refrain from reproducing.

Here’s another point. Let’s talk about fishing. I’ve been hearing about how we fish and hunt. Humans take the biggest and strongest animals and fish from the population in huge numbers. Now, when it comes to cattle and poultry, we raise what we want to eat. But for fish we still get them from the wild in a lot of cases. The impact on those populations has actually caused the fish to evolve, but in a reverse sort of way.

There was this study published recently which I heard about. Basically they took this population of fish and treated them as if they were being fished as is common practice today – taking the biggest, leaving the smallest. After 12 years they found that the fish had to adapt and start reproducing earlier than they used to. This has a negative impact on the population, which then affects what is available for us to harvest.

In the wild a lion will target the weak and the young, which makes sense. But we don’t do that. We go for the biggest and strongest, leaving the young and weak. We seem to do it backwards. Which seems like it’s bad for the rest of the environment.

The good news is that this reverse evolution can be reversed. I found the fishing study. Here’s a link: ‘Undesirable’ Evolution Can Be Reversed In Fish, By Letting The Big Ones Go

Those are just some ideas I’ve been knocking around in my head. Your thoughts are welcome, as usual.

In a giant leap for clean energy, MIT professor Daniel Nocera and his team, have developed a simple method to split water molecules and produce oxygen gas. This paves the way for large scale use of solar power.

Getting energy from the sun isn’t the hard part, it seems. It’s storing that energy that has been a problem.

These guys at MIT were inspired by how plants perform photosynthesis. Their revolutionary method uses abundant, non-toxic natural materials.

I won’t get into all the details, but I just wanted to share it with you because it seems pretty important and wonderful.

Here’s a link to MIT where they have a video of Daniel Nocera describing the new process and a lot more details.

This is just the beginning though. It’s still not really cost effective, but other scientists will be able to run with it and we’ll see where it all leads us in the near future.

Nocera hopes that within 10 years, we’ll be able to power our homes in daylight through photovoltaic cells, while using excess solar energy to produce hydrogen and oxygen to power our own household fuel cell.

Of course, the power companies will not like this. But hopefully it will all happen anyway.

How about a self contained living river ecosystem in your living room? I love the idea of combining art into something practical, useful and also great for the environment, so this really fits the bill. This French designer, Mathieu Lehanneur created a fish hatchery and hydroponic growing system for plants. The water is chilled for the fresh water fish, then the plants get their nutrients from the fish water. They then clean the water for the fish. Brilliant! Of course, Mother Nature came up with the idea first, but hey, it’s still a great idea. Found at Inhabitat.

So, it’s very cool, but I don’t think it would fit into my budget. But I have another idea for you, which I also found at Inhabitat. The Farm Fountain!

Two artists, Amy Youngs and Ken Rinaldo, came up with this clever design. It uses aquaponics to create an ecosystem in your house. The water starts in the fish pond down below. Then the waste water is pumped up to the soda bottle planters and bubbles down through the soilless medium from one level to the next, until it gets back down to the fish. LED growing lights from an inexpensive floor lamp finish the ecosystem. Amy and Ken are really cool, because they give step by step instructions to make your own. Clever stuff! This one is right up my alley and I might have to see if my dear husband would mind having me create this in our home.

I have an Aerogarden which I got recently. I’ve grown some fantastic herbs in it, and will start some tomato plants when they’re finished, but this is even better, because it’s a complete ecosystem.
