Time-keeping Brain Neurons Discovered:
"An MIT team led by Institute Professor Ann Graybiel has found groups of neurons in the primate brain that code time with extreme precision. 'All you do is time stamp everything, and then recalling events is easy: you go back and look through your time stamps until you see which ones are correlated with the event,' she says."

Any time taken away from teachers thinking about and working with their students is wasted time. Teacher time is the scarce resource in school systems. Wasting it increases costs without increasing learning.
My direct experience is in the New York City school systems. I've seen how much money and time is wasted in that context.
With the explosion of great content on the internet this no longer has to be the case. With asynchronous communication on wikis and nings, expert moderated discussions are practical.
With the simple use of a piece of paper and the open source resources on the internet, we can have the same experience we want to give to our students.

Recognition drives segmentation of the speech stream, and segmentation is a critical step in learning a language," Bortfeld explains. "We know from previous research that babies are recognizing their names in fluent speech by the age of six months, so we hypothesized that they should be able to use that recognition to segment the speech stream and recognize new words.
Much in the same way a person might have difficulty understanding a foreign language because it's hard to tell where one word starts and another begins, babies face a similar challenge in learning language. Bortfeld's research shows babies can begin to discern the beginnings and endings of words that follow their names, meaning their names form a foundation for learning language.
In what can be described as a "popping out" pattern, Bortfeld explains, one familiar word can allow a baby to pick out another word, and that newly familiar word may allow a baby to learn words that follow it.read more at Science Daily
The results show that the brain uses the same neural networks to process both familiar and newly learned words.
. . .
In other words, it seems that the processing of meanings in the brain differs essentially from the processing of names. On the other hand, the performance results indicated that new definitions were learned even faster than new names.

"Researchers at the RI-MUHC and McGill University, discovered that hemozoin, a crystal-like substance may be the missing link that explains why malaria leads to devastating inflammation and fever.
'Our results describe the mechanism by which the hemozoin activates the immune system, resulting in the production of inflammation mediators and in the high fever that we witness in malaria patients,' said study first-author Dr. Marina Tiemi Shio of the RI-MUHC.
Hemozoin is first ingested by 'cleaning' cells called macrophages, explained the researcher which leads to a chain reaction ending in the activation of the inflammasome: an important structure inside immune cells which lead to inflammation. Activation of the inflammasome produces the body's fever mediator, interleukin beta (IL-beta)."

After considering carefully the ideas of Jago and Scholes, Langer and Marshall, and a long list of others, I arrived at my own sense of what English is.
We need to do more than teach skills and knowledge: We need to cultivate within our students a range of personae, each of which is necessary if they are, as Jago says, “to make a living, make a life, and make a difference” (2009, 1).
Note that each of the following personae has two sides: one devoted to comprehending, interpreting, and analyzing the text or content created by others; the other side dedicated to communicating one’s own ideas and content through whichever means or media that person deems most appropriate to the task and occasion. In other words, each role involves both comprehension and composition.

Tumor Mutations Can Predict Chemo Success:
"ScienceDaily (Aug. 8, 2009) — New work by MIT cancer biologists shows that the interplay between two key genes that are often defective in tumors determines how cancer cells respond to chemotherapy.
The findings should have an immediate impact on cancer treatment, say Michael Hemann and Michael Yaffe, the two MIT biology professors who led the study. The work could help doctors predict what types of chemotherapy will be effective in a particular tumor, which would help tailor treatments to each patient.
'This isn't something that's going to take five years to do,' says Yaffe, who, along with Hemann is a member of the David H. Koch Institute for Integrative Cancer Research at MIT. 'You could begin doing this tomorrow.'"

I bring this up for two reasons. One, school doors are about to open for the autumn semester and two, schools are publicly concerned about their dropout rate. In Chicago, a good-looking hip-hop artist and recent Chicago Public Schools graduate named Jeremih Felton is encouraging students to remain in school. Calling himself simply Jeremih, the popular singer of the hit song 'Birthday Sex,' and the school district are hoping Jeremih's star power will influence other young people to remain in school. Good for him, although it seems a few people are concerned about some of his hit song's blatantly sexual lyrics. They think perhaps Jeremih is not an appropriate role model for high school students.

"'Our attention is the continual interplay between what our goals are and what the environment is trying to dictate to us,' Vogel said. 'Often, to be able to complete complex and important goal-directed behavior, we need to be able to ignore salient but irrelevant things, such as advertisements flashing around an article you are trying to read on a computer screen. We found that some people are really good at overriding attention capture, and other people have a difficult time unhooking from it and are really susceptible to irrelevant stimuli.'
Vogel theorizes that people who are good at staying on focus have a good gatekeeper, much like a bouncer or ticket-taker hired to allow only approved people into a nightclub or concert. Understanding how to improve the gatekeeper component, he said, could lead to therapies that help easily distracted people better process what information is allowed in initially, rather than attempting to teach people how to force more information into their memory banks."

from Miller-McCune Online Magazine:
"Researchers from the University of London have tested a thesis that may explain why studies of this phenomenon have produced such inconsistent results. In a study just published in the journal Psychology of Music, they conclude that listening to Mozart can indeed spark a certain type of intelligence, but the effect is limited to non-musicians. The reason, it appears, has to do with the different ways musicians and non-musicians process music in the brain.
The term “Mozart effect” can be traced back to a 1993 study, in which a research team led by Frances Rauscher reported that a group of college students outperformed their peers on a test measuring a specific kind of spatial intelligence after listening to one of the Austrian composer’s works: The Sonata for Two Pianos, K. 448.
The test subjects were asked to mentally unfold a piece of paper that had been folded over several times and then cut. Those who listened to Mozart were able to identify the correct shape of the unfolded paper more quickly than those who had sat in silence for 10 minutes, or those who had listened to a tape of relaxing sounds.

St. Louis's Gateway Arch is one of the world's largest optical illusions. It appears to be much taller Gateway-arch than it is wide. The reality is that it is as high as it is wide. The problem is that the illusion can't be overcome just by taking another look -- only an objective measurement will do.
The relationship to unlearning is this: You can't simply rely on what you see to be the sole determinent of truth. In many cases only objective measurement will do.
For example, as I explained in this video, people often "see" patterns when none exist. Alternatively, we tend to view people based more on their surroundings and environment than on who they truly are.If you want to unlearn, my recommendation is to recall the old phrase: "Trust but verify."

"Proponents of the CS claimed that it also provided a wealth of information for non-patient adults and children. However, critics of this system argue that the norms established by CS are out of date and based on small sample sizes. Furthermore, the CS norms are not representative of the population and actually classify a portion of normal subjects as having pathological tendencies. Many studies have also called into question the scoring reliability of the CS; that is, a number of experiments have shown that two practitioners will score one subject very differently using the CS method. The authors observe that 'disagreements can have particularly serious implications if the test results are used to reach important clinical or legal recommendations.'

. . .
A team led by Professor Frances Gardner from the Department of Social Policy and Social Work at the University of Oxford found no evidence of a general decline in parenting. Their findings show that differences in parenting according to family structure and income have narrowed over the last 25 years. However, the task of parenting is changing and could be getting increasingly stressful, particularly for some groups.
. . .
The research highlights a different set of challenges for parents compared with 25 years ago. Young people now are reliant on their parents for longer, with higher proportions of 20–24 year olds living with their parents. Many more remain in some kind of education or training into their late teens. In addition, the development of new technology, such as mobile phones and the Internet, has created new monitoring challenges for parents.
'Today’s parents have had to develop skills that are significantly different and arguably more complex than 25 years ago, and this could be increasing the stress involved in parenting,’ Professor Gardner said.
Twitter - Wikipedia, the free encyclopedia:
Twitter is a free social networking and micro-blogging service that enables its users to send and read messages known as tweets. Tweets are text-based posts of up to 140 characters displayed on the author's profile page and delivered to the author's subscribers who are known as followers. Senders can restrict delivery to those in their circle of friends or, by default, allow open access. Users can send and receive tweets via the Twitter website, Short Message Service (SMS) or external applications. While the service costs nothing to use, accessing it through SMS may incur phone service provider fees.
Since its creation in 2006 by Jack Dorsey, Twitter has gained notability and popularity worldwide. It is sometimes described as the "SMS of the Internet" since the use of Twitter's application programming interface for sending and receiving short text messages by other applications often eclipses the direct use of Twitter.
Twitter is ranked as one of the 50 most popular websites worldwide by Alexa's web traffic analysis. Although estimates of the number of daily users vary because the company does not release the number of active accounts, a February 2009 Compete.com blog entry ranked Twitter as the third most used social network based on their count of 6 million unique monthly visitors and 55 million monthly visits. In March 2009, a Nielsen.com blog ranked Twitter as the fastest-growing site in the Member Communities category for February 2009. Twitter had a monthly growth of 1,382 percent, Zimbio of 240 percent, followed by Facebook with an increase of 228 percent. However, only 40 percent of Twitter's users are retained.

Designing chip architecture for the best performance and smallest size is an exceedingly difficult task that's outsourced to computers these days.

History of attention-deficit hyperactivity disorder - Wikipedia, the free encyclopedia:
Hyperactivity has long been part of the human condition. Sir Alexander Crichton describes "mental restlessness" in his 1798 book. The terminology used to describe the symptoms of ADHD has gone through many changes over history including: "minimal brain damage", "minimal brain dysfunction", "learning/behavioral disabilities" and "hyperactivity". In the DSM-II (1968) it was the "Hyperkinetic Reaction of Childhood". In the DSM-III "ADD (Attention-Deficit Disorder) with or without hyperactivity" was introduced. In 1987 this was changed to ADHD in the DSM-III-R and subsequent editions.

Cortechs Labs - About CorTechs Labs : Company Overview: "CorTechs Labs Inc is a group of scientists, engineers, business professionals, and clinical specialists dedicated to bringing cutting edge brain image analysis technologies to the commercial market.
CorTechs was incorporated in 2001 by leaders in neuroimaging research in order to create advanced medical image analysis solutions for quantitative analysis of the structure and function of the human brain. An extensive and growing body of scientific and clinical research indicates that such tools may help physicians to more effectively diagnose and treat serious neurological disorders that affect millions of patients worldwide. It is our mission to effectively translate the fruits of such research into routine clinical practice.
Many empirical studies have shown that neurodegenerative disorders produce changes in the brain that can be measured with MRI scanning. Accurately characterizing the extent and progression of cortical atrophy from MRIs can only be accomplished only by comparing numerical information with normative data. Existing semi-manual methods for deriving numerical information from MRI scans are too slow and expensive for use outside of small research studies, and lack the reliability necessary for routine clinical application. CorTechs' quantitative image analysis technologies offer a solution to this problem."

Songbirds’ Elaborate Cries For Food Show First Signs Of Vocal Learning:
"ScienceDaily (July 27, 2009) — Only a handful of social animals — songbirds, some marine mammals, some bats and humans — learn to actively style their vocal communications. Babies, for instance, start by babbling, their first chance to experiment with sounds. Now, new research in songbirds shows that vocal experimentation may begin with their earliest vocalizations — food begging calls — and perhaps for a more devious reason than previously believed. The findings could change the way we think about the evolution of vocal learning."
It may have started as cheating,” says Fernando Nottebohm, head of the Laboratory of Animal Behavior at The Rockefeller University. “By generating a diversity of calls, young birds may trick their parents into losing track of whom they last fed, in effect creating the impression of several individuals.” In this scenario, the most agile vocal dissembler would get more than its fair share of food at the expense of its siblings.
Nottebohm and Wan-chun Liu, a research assistant professor who made the original observations, are quick to say that the interpretation remains speculative for now, but if true, it would complicate the conventional wisdom that vocal learning evolved as an adjunct to reproductive behavior. In temperate climates, most often only male songbirds sing. The message conveyed by song is simple: I am a male robin, mature, single and ready to breed; females are welcome, males stay away. Depending on the listener, song is a lure or a threat. By imitating the song of established seniors with whom they would have to compete, young breeders presumably gained an advantage in courtship and territorial defense.The vocal imitation expressed by adults, however, is a complex behavior requiring sophisticated underlying brain circuits, Nottebohm says. How would birds with only innate, genetically foreordained vocal repertoires have evolved the ability?
. . .
Males producing food begging calls also showed an increased expression of c-fos, a neural activity marker in a section of the forebrain known as the robust nucleus, which later plays a role in the control of learned song.
Here's how that plays out with scientists who study human languages.

If You're Happy, Then We Know It: New Research Measures Mood:
". . . what if you had a remote-sensing mechanism that could record how millions of people around the world were feeling on any particular day — without their knowing?
That's exactly what Peter Dodds and Chris Danforth, a mathematician and computer scientist working in the Advanced Computing Center at the University of Vermont, have created.
Their methods show that Election Day, November 4, 2008, was the happiest day in four years. The day of Michael Jackson's death, one of the unhappiest.
'The proliferation of personal online writing such as blogs gives us the opportunity to measure emotional levels in real time,' they write in their study, 'Measuring the Happiness of Large-Scale Written Expression: Songs, Blogs, and Presidents,3' now available in an early online edition of the journal.
Their answer to Edgeworth's daydream begins with a website, http://www.wefeelfine.org4 that mines through some 2.3 million blogs, looking for sentences beginning with "I feel" or "I am feeling."
"We gathered nearly 10 million sentences from their site," Dodds says. Then, drawing on a standardized "psychological valence" of words established by the Affective Norms for English Words (ANEW) study, each sentence receives a happiness score. In the ANEW study, a large pool of participants graded their reaction to 1,034 words, forming a kind of "happy-unhappy" scale from 1 to 9. For example, "triumphant" averaged 8.87, "paradise" 8.72, "pancakes" 6.08, "vanity" 4.30, "hostage" 2.20, and "suicide" 1.25.

NNSF Funds Science of Learning Center at Dartmouth -
US National Science Foundation (NSF)
"Center for Cognitive and Educational Neuroscience will study the mechanisms of human learning across contexts
February 1, 2005
This material is available primarily for archival purposes. Telephone numbers or other contact information may be out of date; please see current contact information at media contacts.
ARLINGTON, Va.--The National Science Foundation (NSF) has awarded $21.8 million to Dartmouth College to establish the Center for Cognitive and Educational Neuroscience (CCEN). The CCEN comprises a multidisciplinary team that includes cognitive neuroscience, psychology, and education to explore how the human brain’s learning processes interact with educational experiences across the lifespan.
The CCEN team will address such complex questions as:
* What are the “windows” for learning as a child develops?
* How do social, emotional and cultural factors influence learning?
* Why are some things hard to learn?
* What factors contribute to the successful transfer of learning from one field of knowledge to another?"
. . .
“Questions like these call for the kind of integrated, interdisciplinary work fostered by a Science of Learning Center,” said Soo-Siang Lim, lead program officer for the NSF’s Science of Learning initiative. “With the Dartmouth center and the other three centers at University of Washington, Boston University, and Carnegie Mellon University, NSF is poised to see breakthrough research in fundamental questions about how people learn.”
"To understand how children learn and improve our educational system, we need to understand what all of these fields can contribute,” explains Howard Hughes Medical Institute investigator Terrence J. Sejnowski, Ph.D., professor and head of the Computational Neurobiology Laboratory at the Salk Institute for Biological Studies and co-director of the Temporal Dynamics of Learning Center (TDLC) at the University of California, San Diego, which is sponsored by the National Science Foundation. “Our brains have evolved to learn and adapt to new environments; if we can create the right environment for a child, magic happens.”"
Multitasking Ability Can Be Improved Through Training: "'We found that a key limitation to efficient multitasking is the speed with which our prefrontal cortex processes information, and that this speed can be drastically increased through training and practice,” Paul E. Dux, a former research fellow at Vanderbilt, and now a faculty member at the University of Queensland in Brisbane, Australia, and co-author of the study, said. “Specifically, we found that with training, the 'thinking' regions of our brain become very fast at doing each task, thereby quickly freeing them up to take on other tasks.'"

I’m talking about questions like,
“What is your favorite song?”

“What single malt whisky do you like best.”
I answer questions like that by saying it is a matter of context. When selecting a whisky to sip on during an evening of conversation with friends (defined as people who have never asked me anything like one of the questions above) I sometimes enjoy the peppery flavor of Talisker, but on a damp foggy night in late autumn when I am sitting in my chair reading and listening to the muffled sounds outside, the iodine-laced Laphroaig appeals to me. Or when looking for a light refreshment….
At some point I’ll really hit my stride and say something like, “you see, context determines everything, even what we call disabilities.”A long time ago I was involved in the disability rights movement on Cape Cod. This was long before the American with Disabilities Act. I belonged to an organization whose main activities involved teaching what I then considered to be “normal” people (I know, but I was young and foolish and this story is about how I learned better) about disabilities.
Kids and editors looking for copy are always prowling around for the top ten, top 100, top 1000. It’s very satisfying because it’s about “me” or “people like us.”
It always feels good to be part of a tribe. As long as you don’t mix up “me” or “people like us’ with everyone else.

A study published in the February issue of the Journal of Educational Psychology found that just 9% of American high school students use an in-class computer more than once a week. The cause of the decline in handwriting may lie not so much in computers as in standardized testing.
The Federal Government's landmark 1983 report A Nation at Risk, on the dismal state of public education, ushered in a new era of standardized assessment that has intensified since the passage in 2002 of the No Child Left Behind Act. "In schools today, they're teaching to the tests," says Tamara Thornton, a University of Buffalo professor and the author of a history of American handwriting. "If something isn't on a test, it's viewed as a luxury." Garcia agrees. "It's getting harder and harder to balance what's on the test with the rest of what children need to know," she says. "Reading is on there, but handwriting isn't, so it's not as important." In other words, schools don't care how a child holds her pencil as long as she can read.

Presented at the 2009 Personal Democracy Forum at Jazz at Lincoln Center. About 10 minutes of it is a minor update (rehash) of An Anthropological Introduction to YouTube, but the rest is new. The gathering may have been the highest concentration of amazingly creative and concerned global citizens I have ever been around. Hallway conversations were different than your typical conversations. Instead of lots of people saying, 'You know, somebody should ...' there were lots of people saying, 'So I did this, this, and this, and now Im working on doing this, this, and this and we should collaborate ...' In other words, it was a bunch of people blessed with what I once heard Yochai Benkler and Henry Jenkins call critical optimism. Nobody there was blindly optimistic, thinking technology was going to make everything better. They were all continually trying to figure out where we are, where we might be going, and the possible downsides and dangers of new technologies so we can use the new technologies to serve human purposes. In other words, it was my kind of crowd. Special thanks to Micah Sifry and Andrew Rasiej for organizing the conference.

The Future of Education: Technology and How People Learn:
. . . "Gardner gives us the Five Minds in Under Five Minutes (pretty impressive speed here…): the five are the disciplined mind, the synthesizing mind, the creating mind, the respectful mind, and the ethical mind. The disciplined mind is about becoming an expert in something. It’s hard to imagine that the digital media are helping in this respect. The synthesizing mind, some have said, is the most important in the digital era: to sort through lots more information than has ever before been available to human beings. Digital natives like to search, but it’s unclear that they are in fact good at it. The creating mind comes up with new approaches, new methods. Creating minds think outside the box — but you need the box first, which are from your discipline and your synthesis. One of the big questions: can these media help creativity, or might they instead inhibit creativity, by giving too much of a frame and discouraging going beyond that box.
. . . There’s a mimicking of biology: instead of top-down control, we see a bottom-up, evolutionary-based set of rules, based on parallelism rather than serialism. Wright applies a Darwinian analogy, echoing the set of Darwin-related themes bouncing around Aspen this week.
Engineering Students Rock -- Mechanical Engineers Rock Out On Guitars They Construct Themselves:
January 1, 2009 — Mechanical engineers combined their skills with that of electrical engineering and computer science to create a college class inspired by the Guitar Hero game. The hands-on course requires students to build their own guitar. To do this, students choose a shape for the guitar, which is cut out of lumber by a computer. Located under the guitar strings, magnets detect vibrations and wire coils send an electronic signal to an amplifier and speaker. Effects pedals can also distort the sound and add special effects."

"The enzyme known as DNA polymerase V (pol V) comes in when a cell's DNA is reeling from radiation damage or other serious blows. Pol V copies the damaged DNA as best it can – saving the life of the bacterial cell at the cost of adding hundreds of random mutations.
The July 16 Nature study reveals pol V's key attributes: economy of motion and quickness to engage.
The study also solves two other stubborn mysteries about the mechanics of DNA repair: the exact composition of the active form of pol V and the crucial role of a protein filament, known as RecA*, that is always present around DNA repair sites, but was never shown to be directly involved."
The Good Life: Where Psychology Stands On Living Well:
"So far we have learned from psychology that a good life includes experiencing more positive than negative feelings, feeling like your life has been lived well, continually using your talents and strengths, having close interpersonal relationships, being engaged at work and other activities, being a part of a social community, perceiving that life has a meaning, and feeling healthy and safe. And while these conclusions may seem like common sense, we as humans fall short on knowing just how to obtain and maintain these qualities.
Psychology still has a ways to go until the perfect formula for a good life is found. As Park and Peterson put it, "At present, psychology knows more about people's problems and how to solve them than it does about what it means to live well and how to encourage and maintain such a life." They suggest researchers across all disciplines of psychology come together and collaborate on their findings, perhaps pulling together a more complete picture of the human experience.

Potential New Drug Target For Diabetes And Alzheimer's Disease
"The study, which focuses on diabetic rodents, appears this month in PLoS One and is the first to show a role in glucose metabolism for humanin, a small protein (peptide). The researchers also demonstrated that humanin resembles the peptide leptin by acting on the brain to influence glucose metabolism.
Humanin is found in mitochondria — structures that populate the cytoplasm of cells and provide them with energy. The peptide was first detected in brain nerve cells in 2001, and subsequent studies suggest that it protects nerve cells from death associated with Alzheimer's and other brain disease."

"As technology advances, new discoveries based on brain mapping are helping researchers understand how students learn. And those discoveries, in turn, are enriching and informing classroom practices in a growing number of schools.
Thanks to functional Magnetic Resonance Imaging (fMRI)--a type of non-invasive, low-radiation brain scan that measures neural activity in response to certain stimuli, and the most recently developed forms of neuroimaging--researchers are learning more about how we learn than many thought possible."

Top News - What educators can learn from brain research:
Amazing stat of the day: Newsweek's paid newsstand circulation is less than 67,000 copies a week: "Newsweek lost $20.3 million in the first quarter of this year on revenue of $46.1 million. Those are ugly numbers. But given the circulation statistics, they're hardly surprising. It's a little hard to see why—especially in an age of real-time online news—The Washington Post Co. is keeping Newsweek alive. Readers (and advertisers) just don't seem to care."
Misdiagnosis Of Disorders Of Consciousness Still Commonplace:
"ScienceDaily (July 21, 2009) — A sixteen-month study of consensus-based diagnosis of patients with disorders of consciousness has shown that 41% of cases of minimally conscious state (MCS) were misdiagnosed as vegetative state (VS), a condition associated with a much lower chance of recovery. Researchers have demonstrated that standardized neurobehavioral assessment is more sensitive than diagnoses determined by clinical consensus.
The researchers prospectively followed 103 patients with mixed etiologies and compared the clinical consensus diagnosis provided by the physician on the basis of the medical staff's daily observations to diagnoses derived from the CRS-R. They found that of the 44 patients diagnosed with VS based on the clinical consensus of the medical team, 18 (41%) were found to be in MCS following standardized assessment with the CRS-R. According to Laureys, "It is likely that the examiners' reliance on unstructured bedside observations contributed to the high rate of misdiagnosis of VS patients. Unlike traditional bedside assessment, the CRS-R guards against misdiagnosis by incorporating items that directly reflect the existing diagnostic criteria for MCS, and by operationalizing scoring criteria for the identification of behaviors associated with consciousness".
The researchers conclude, "The results of this study suggest that the systematic use of a sensitive standardized neurobehavioral assessment scale may help decrease diagnostic error and limit diagnostic uncertainty".
They found, surprisingly, that 3-D motion processing occurs in an area in the brain—located just behind the left and right ears—long thought to only be responsible for processing two-dimensional motion (up, down, left and right).
This area, known simply as MT , and its underlying neuron circuitry are so well studied that most scientists had concluded that 3-D motion must be processed elsewhere. Until now."

Amber M. Epp (University of Wisconsin-Madison) and Linda L. Price (University of Arizona, Tucson) conducted a two-year case study that tracked the origins, movements, and placement of one family's objects. "It is not necessarily the history of an object that rescues it from being discarded, but also its place in a network of other objects, practices, and spaces that determine whether and when it's replaceable," the authors write.
"Our study suggests that families should consider the downstream consequences when introducing new products or services into their homes," the authors write. "It's important for families to be conscious about which activities or objects are important to preserve, especially during times of change."

If the object is to improve learning, it makes sense to define the terms. The learning we're interested is the kind that is best done by children coming of age. That's usually between about 13 and 20 years old. The place where that is supposed to happen is in last years of high school and first years of college.
Learning is acquiring new knowledge, behaviors, skills, values, preferences or understanding, and may involve synthesizing different types of information. The ability to learn is possessed by humans, animals and some machines. Progress over time tends to follow learning curves.
Human learning may occur as part of education or personal development. It may be goal-oriented and may be aided by motivation. The study of how learning occurs is part of neuropsychology, educational psychology, learning theory, and pedagogy.Learning may occur as a result of habituation or classical conditioning, seen in many animal species, or as a result of more complex activities such as play, seen only in relatively intelligent animals and humans. Learning may occur consciously or without conscious awareness. There is evidence for human behavioral learning prenatally, in which habituation has been observed as early as 32 weeks into gestation, indicating that the central nervous system is sufficiently developed and primed for learning and memory to occur very early on in development.
Her research explores the notion that teaching native pronunciation might eliminate a significant indicator of an individual’s identity. She said, “We recognise Indian, South African, Egyptian and Chinese speakers from their accents. As long as they are intelligible and have the potential to communicate effectively there should be no reason for them not to retain their accents – something which they might like to do as this accent carries their identity, ethnicity and indicates the group of people they belong to.”"

'Heart Healthy' Diet And Ongoing, Moderate Physical Activity May Protect Against Cognitive Decline:
"ScienceDaily (July 20, 2009) — Eating a 'heart healthy' diet and maintaining or increasing participation in moderate physical activity may help preserve our memory and thinking abilities as we age, according to new research reported July 14 at the Alzheimer's Association 2009 International Conference on Alzheimer's Disease (ICAD 2009) in Vienna.
. . .
Studies have found that older adults who are physically active may experience slower rates of cognitive decline. Less is known about the impact of changes in physical activity levels on rate of cognitive decline.
. . .
Alzheimer's Risk Gene May Reduce Benefits of Physical Activity to Cognitive Ability
While the relationship of physical activity with cognitive performance as we age is a subject of considerable research, much less is known about how this relationship is impacted by the Alzheimer's risk gene Apolipoprotein E (APOE). The APOE gene comes in three types, or alleles, known as e2, e3, and e4. Each person gets one type of APOE from each parent, making the possible combinations: e2/e2, e2/e3, e2/e4, e3/e3, e3/e4, e4/e4. Having two copies of e4 conveys the highest risk for Alzheimer's; having one e4 also raises one's risk. E3 is the most common type. E2, though rare, is thought to be protective.
. . .
n their analysis, the researchers found that physical activity was associated with enhanced cognitive function, and that this relationship was differentially influenced by the person's APOE genotype: non-E4 carriers and people with one copy of E4 performed better than people with two copies of E4. After adjusting for age, ethnicity, severe chronic medical illness, lean body mass, and education, aerobic physical activity continued to show a statistically significant association with cognitive function in non-E4 carriers but not in people with E4 (any combination)
"In our nationally representative sample, persons who reported higher levels of aerobic physical activity had better memory than those who reported no such activity. This was especially true in those people who didn't have the APOE-e4 Alzheimer's risk gene," Obisesan said.
"Because physical activity is a low-cost, low-risk, readily available intervention, it may prove to be an important public health strategy to reduce or prevent memory loss and other symptoms of mental decline in the elderly. Future rigorous clinical trials are needed to confirm these findings," Obisesan added.
Could Older Population Have Enough Exposure To Past H1N1 Flu Strains To Avoid Infection?: "ScienceDaily (June 25, 2009) — A letter to the editor by Rhode Island Hospital infectious diseases specialist Leonard Mermel, DO, identifies characteristics of the outbreak of H1N1 in 1977 and speculates its impact on this pandemic.
Mermel notes that in the late 1970s, an influenza H1N1 reappeared in humans. It had a pandemic-like spread that began in younger aged individuals. This strain, known as the "Russian flu" H1N1, was similar to H1N1 strains that circulated internationally between 1946 and 1957. The Russian flu spread rapidly across the former Soviet Union, initially affecting individuals between the ages of 14 and 20 in schools, as well as young military personnel, and later spread to preschool children. Individuals older than age 30, however, had dramatically lower attack rates and the overall mortality was low. The epidemic peaked rapidly, with a relatively short duration.
H1N1 Influenza Pandemic Modeling For Public Health Action: "ScienceDaily (July 21, 2009) — Mathematical modelling can help inform public health policy in outbreaks such as the H1N1 pandemic, write members of the Pandemic Influenza Outbreak Research Modelling Team in Canada in a CMAJ (Canadian Medical Association Journal) article. These models are useful tools for simulating plausible scenarios, developing control strategies and identifying important areas for immediate research.
. . .
Mathematical models have shown that small seasonal variations in transmission of the influenza virus can drive large annual surges in the disease.
. . .
The authors conclude that "making these models better understood and more accessible will provide a valuable additional weapon in the fight against emerging infectious diseases."
In a related article, Canada's first human-to-human transmission of the H1N1 influenza virus is presented in a research case study. The article looks at the cluster of cases in Nova Scotia in April 2009 and outlines transmission, diagnostic testing and public health measures to control the outbreak.

Brain Response To Information About The Future Suggests That Ignorance Isn't Bliss: "The authors conclude that the same dopamine neurons that signal primitive rewards like food and water also signal the cognitive reward of advance information. Importantly, this finding has important implications for modern theories of reinforcement learning. 'Our data shows the need for a new class of models that assign information a positive value,' says Dr. Bromberg-Martin. 'Dopamine neurons might treat information as desirable because it can help us learn how to predict and control our environment.'"
Trying to learn how learning works - USATODAY.com:
"'New insights from many different fields are converging to create a new science of learning that may transform educational practices,' begins a report led by Andrew Meltzoff of the University of Washington in Seattle. The review in the current Science magazine makes the case for psychologists, neuroscientists, roboticists and teachers combining to quietly create a new field that combines everything from how brains grow to how classrooms work into a new kind of learning research.
For example, a companion study in the current Science by John Gabrieli of the Massachusetts Institute of Technology, illustrates how neuroscience and education researchers have teamed up to tackle dyslexia, a difficulty with reading and vocabulary that afflicts 5% to 17% of children. Behavioral and brain measures can now identify dyslexic tendencies in infants, and lead to teaching that can "prevent dyslexia from occurring in the majority of children who would otherwise develop dyslexia," according to the study.

Delinquent Behavior Among Boys 'Contagious,' Study Finds: "The more intense the help given by the juvenile justice system, the greater was its negative impact,' Dr. Tremblay stresses. 'Our findings take on even greater importance given that the juvenile justice system in the province of Quebec has the reputation of being among the best. Most countries spend considerable financial resources to fund programs and institutions that group deviant youths together in order to help them. The problem is that delinquent behavior is contagious, especially among adolescents. Putting deviant adolescents together creates a culture of deviance, which increases the likelihood of continued criminal behavior.
Learning Is Both Social And Computational, Supported By Neural Systems Linking People:
"ScienceDaily (July 19, 2009) — Education is on the cusp of a transformation because of recent scientific findings in neuroscience, psychology, and machine learning that are converging to create foundations for a new science of learning.
Writing in the July 17 edition of the journal Science, researchers report that this shift is being driven by three principles that are emerging from cross-disciplinary work: learning is computational, learning is social, and learning is supported by brain circuits linking perception and action that connect people to one another. This new science of learning, the researchers believe, may shed light into the origins of human intelligence.
"We are not left alone to understand the world like Robinson Crusoe was on his island," said Andrew Meltzoff, lead author of the paper and co-director of the University of Washington's Institute for Learning and Brain Sciences. "These principles support learning across the life span and are particularly important in explaining children's rapid learning in two unique domains of human intelligence, language and social understanding.
"Social interaction is more important than we previously thought and underpins early learning. Research has shown that humans learn best from other humans, and a large part of this is timing, sensitive timing between a parent or a tutor and the child," said Meltzoff, who is a developmental psychologist.
"We are trying to understand how the child's brain works – how computational abilities are changed in the presence of another person, and trying to use these three principles as leverage for learning and improving education," added co-author Patricia Kuhl, a neuroscientist and co-director of the UW's Institute for Learning and Brain Sciences.

Unlike a textbook, it could be delivered fresh every day or every week. When students get fresh food for thought, it's much more likely that they will think. If CodeZ QR is embedded, it gives the teacher/mentor information about which student is looking, when and where. That information can be shared with parents and other teachers. As that body of information is analyzed, it will make it practical for the teacher to use it to plan appropriate interventions.
