The link between circadian rhythms and aging

Human sleeping and waking patterns are largely governed by an internal circadian clock that corresponds closely with the 24-hour cycle of light and darkness. This circadian clock also controls other body functions, such as metabolism and temperature regulation.<p>Studies in animals have found that when that rhythm gets thrown off, health problems including obesity and metabolic disorders such as diabetes can arise. Studies of people who work night shifts have also revealed an increased …

How neural stem cells create new and varied neurons

A new study examining the brains of fruit flies reveals a novel stem cell mechanism that may help explain how neurons form in humans. A paper on the study by researchers at the University of Oregon appeared in the online version of the journal <i>Nature</i> in advance of the June 27 publication date.<p>“The question we confronted was ‘How does a single kind of stem cell, like a neural stem cell, make all different kinds of neurons?’” said Chris Doe, a biology professor and co-author on the paper …

It’s the way you tell em’: Study discovers how the brain controls accents and impersonations

A study, led by Royal Holloway University researcher Carolyn McGettigan, has identified the brain regions and interactions involved in impersonations and accents.<p>Using an fMRI scanner, the team asked participants, all non-professional impressionists, to repeatedly recite the opening lines of a familiar nursery rhyme either with their normal voice, by impersonating individuals, or by impersonating regional and foreign accents of English.<p>They found that when a voice is deliberately changed, it …

The Present and Future of Neurogenomics

<i>Support the BRAIN Initiative, but don’t overlook the neurogenomic diagnostics that are already driving breakthroughs in brain and rare neurological disorders.</i><p>On April 2nd, 2013, President Obama proposed a forward-thinking, $100 million research program designed to unlock the mysteries of the human brain. The BRAIN (Brain Research through Advancing Innovative Neurotechnologies) Initiative seeks to identify how brain cells and neural circuits interact in order to inform the development of future …

The quest to build a brain in the lab

<b>The quest to build a brain in the lab</b><p>“I’m a neuroengineer, and one of my goals is building brains.”<p>Prof Steven Potter was disarmingly understated as he introduced himself.<p>It’s not that tissue engineering is unusual. Nor even that doing it with neural cells should be an issue.<p>If heart cells or skin cells can be reprogrammed, why not neurons?<p>But “building brains” had been my flip way of labelling an intriguing, indeed unnerving, branch of science: the neurophysiology of disembodied brain-cell …

People can sense a smile before it appears on the face

In the lab, the results were repeated and data from electrical sensors on participants’ faces revealed that they engaged smile-related muscles when they expected a genuine smile to appear but showed no such activity when expecting polite smiles.<p>The different responses suggest that genuine smiles are more valuable social rewards, said Dr Erin Heerey.<p>She said: “These findings give us the first clear suggestion that the basic processes that guide responses to reward also play a role in guiding …

Could this be the secret to limb regrowth in humans?

Gustatory Tug-of-war Key To Whether Salty Foods Taste Good

<b>Fruit fly’s salt taste sensation strategy may apply to other animals, including humans</b><p>As anyone who’s ever mixed up the sugar and salt while baking knows, too much of a good thing can be inedible. What hasn’t been clear, though, is how our tongues and brains can tell when the saltiness of our food has crossed the line from yummy to yucky — or, worse, something dangerous.<p>Now researchers at the Johns Hopkins University School of Medicine and the University of California, Santa Barbara report that …

New Molecular-Level Understanding of Brain’s Recovery After Stroke

A specific MicroRNA, a short set of RNA (ribonuclease) sequences, naturally packaged into minute (50 nanometers) lipid containers called exosomes, are released by stem cells after a stroke and contribute to better neurological recovery according to a new animal study by Henry Ford Hospital researchers.<p>The important role of a specific microRNA transferred from stem cells to brain cells via the exosomes to enhance functional recovery after a stroke was shown in lab rats. This study provides …

Study finds brain-imaging technique can help diagnose movement disorders

A new University of Florida study suggests a promising brain-imaging technique has the potential to improve diagnoses for the millions of people with movement disorders such as Parkinson’s disease.<p>Utilizing the diffusion tensor imaging technique, as it is known, could allow clinicians to assess people earlier, leading to improved treatment interventions and therapies for patients.<p>The three-year study looked at 72 patients, each with a clinically defined movement disorder diagnosis. Using a …

Testing method promising for spinal cord injuries, multiple sclerosis

A medical test previously developed to measure a toxin found in tobacco smokers has been adapted to measure the same toxin in people suffering from spinal cord injuries and multiple sclerosis, offering a potential tool to reduce symptoms.<p>The toxin, called acrolein, is produced in the body after nerve cells are injured, triggering a cascade of biochemical events thought to worsen the injury’s severity. Acrolein (pronounced a-KRO-le-an) also may play an important role in multiple sclerosis and …

New tasks become as simple as waving a hand with brain-computer interfaces

Small electrodes placed on or inside the brain allow patients to interact with computers or control robotic limbs simply by thinking about how to execute those actions. This technology could improve communication and daily life for a person who is paralyzed or has lost the ability to speak from a stroke or neurodegenerative disease.<p>Now, University of Washington researchers have demonstrated that when humans use this technology – called a brain-computer interface – the brain behaves much like it …

Video Gamers Really Do See More

Hours spent at the video gaming console not only train a player’s hands to work the buttons on the controller, they probably also train the brain to make better and faster use of visual input, according to Duke University researchers.<p>“Gamers see the world differently,” said Greg Appelbaum, an assistant professor of psychiatry in the Duke School of Medicine. “They are able to extract more information from a visual scene.”<p>It can be difficult to find non-gamers among college students these days, …

A rather complex complex: Brain scans reveal internal conflict during Jung's word association test

Over 100 years ago psychologist Carl Gustav Jung penned his theory of ‘complexes’ where he explained how unconscious psychological issues can be triggered by people, events, or Jung believed, through word association tests.<p>New research in the <i>Journal of Analytical Psychology</i> is the first to reveal how modern brain function technology allows us to see inside the mind as a 'hot button’ word triggers a state of internal conflict between the left and right parts of the brain.<p>The study revealed that …

Creativity Linked with Deficit in Mental Flexibility

Creative types are often seen as rather flaky — their minds leaping wildly from one bizarre idea to another, ever seeking inspiration. But a new study suggests that people who actually achieve creative success have minds that stubbornly cling to ideas, even to the point where it impairs their ability to shift focus.<p>In one experiment, researchers at Northwestern University in Illinois selected 34 students out of more than 300 who completed a questionnaire on creative achievement, ultimately …

Indie RPGs developers call back to mechanics and tropes from the genre's birth

Mystery of Moon’s Magnetic Field Deepens

The moon generated a surprisingly intense magnetic field until at least 3.56 billion years ago, 160 million years longer than previously thought, a new study reports.<p>These findings could shed light not just on the magnetic field of the moon, which is now extremely weak, but on that of asteroids and other distant worlds, investigators added.

If you haven’t seen the There She Is!! series—you have no idea what you are missing.<p>I saw the very first There She Is!! when I was very, very little. Internet was still new and my brother and I watched it together when we were allowed thirty minutes of internet time each. Years later, in middle school, I rediscovered it—only to find that there were now three episodes, and the fourth was very near to releasing. It was the cutest thing ever!<p>Until the Fourth Step came out and shattered my heart. …
