We’re at APS all week, come by and test drive Google Glass!… come by the Cengage booth if you can’t make these activities… we’ll tweet out the times!

Here’s what we are reading today:

“It’s well known that people marry folks who are like them,” said Benjamin Domingue, lead author of the paper and a research associate at CU-Boulder’s Institute of Behavioral Science. “But there’s been a question about whether we mate at random with respect to genetics.”

For the study, Domingue and his colleagues, including CU-Boulder Associate Professor Jason Boardman, used genomic data collected by the Health and Retirement Study, which is sponsored by the National Institute on Aging.”

“The Alzheimer’s Association estimates that the number of Americans living with Alzheimer’s disease will increase from 5 million in 2014 to as many as 16 million by 2050. Memory impairments and other early symptoms of Alzheimer’s are often difficult to differentiate from the effects of normal aging, making it hard for doctors to recommend treatment for those affected until the disease has progressed substantial…”

 

The 'other doctor Freberg" is Karen Freberg an assistant professor of social media at the university of Louisville. Poor Karen, after demonstrating Google Glass all day, she took a three hour nap! Not to worry, she's ready to go today!!

“Our results can be interpreted two ways,” said Rebecca Knickmeyer, PhD, assistant professor of psychiatry in the UNC School of Medicine and lead author of the study published May 19 in the journal Neuropsychopharmacology. “Either SSRIs increase risk for Chiari type 1 malformations, or other factors associated with SSRI treatment during pregnancy, such as severity of depression itself, increase risk. Additional research into the effects of depression during pregnancy, with and without antidepressant treatment is urgently needed.”

“In a study published in the Journal of Memory and Language, Michael Vitevitch, KU professor of psychology, showed that research participants recognized these keywords more quickly and accurately than other words that were like the keywords in many respects except for their position in a network of 20,000 similar-sounding English words that he and colleagues created in 2008.”

“Looking at the activity of just one neuron in the brain doesn’t tell you how that information is being computed; for that, you need to know what upstream neurons are doing. And to understand what the activity of a given neuron means, you have to be able to see what downstream neurons are doing,” says Ed Boyden, an associate professor of biological engineering and brain and cognitive sciences at MIT and one of the leaders of the research team. “In short, if you want to understand how information is being integrated from sensation all the way to action, you have to see the entire brain.”

“According to Marcus Raichle (2010), some of the earliest indications that the brain was not exactly quiet during daydreaming or mind wandering came from observations made by Hans Berger, inventor of the EEG, in 1929. Berger wrote that the brain seemed to be “in a state of considerable activity” all the time, and not just during active wakefulness.”

My daughter Karen calls us “Dr. Freberg and Dr. Freberg 2.0 (two point oh). We’ll be presenting at this years Association for Psychological Sciences Convention in San Francisco this month… and demonstrating and discussing Google Glass… catch us and we’ll show you how it works!

“Paleontologists in Argentina say they recently discovered fossils belonging to the largest dinosaur on record. During its lifetime, the new species of titanosaur is believed to have stood 65-feet-tall, was more than 130-feet-long, and weighed 77 tons (155,000 pounds).

“Given the size of these bones, which surpass any of the previously known giant animals, the new dinosaur is the largest animal known that walked on Earth,” researchers Dr. Jose Luis Carballido and Dr. Diego Pol told the BBC.”

“In his epic encyclopedia Natural History, the great Roman naturalist Pliny the Elder wrote of the bonnacon, a sort of bull whose defensive strategy was to hit its foes with blasts of dung “so strong and hot, that it burneth them that follow after him in chase, like fire, if haply they touch it.” Natural history in Pliny’s time, you see, consisted of a good amount of hearsay. From 12-year-old boys, apparently.”

““The loss of bitter taste is a complete surprise, because natural toxins typically taste bitter,” says zoologist Huabin Zhao of Wuhan University in China who led the study. All whales likely descend from raccoon-esque raoellids, a group of herbivorous land mammals that transitioned to the sea where they became fish eaters.”

“The technique relies on electrically stimulating the nerve pathways in the spinal cord. “In the injured area, the nerve cells have been damaged to such an extent that they no longer receive usable information from the brain, so the stimulation needs to be delivered beneath that,” explains Dr. Peter Detemple, head of department at the Fraunhofer Institute for Chemical Technology’s Mainz branch (IMM) and NEUWalk project coordinator.”

“”I think if anybody ever had a doubt that this was just some sort of odd pickiness or something like that in people with autism, this shows, no, there really is a brain basis for this,” said Dr. Paul Wang, head of medical research for nonprofit advocacy group Autism Speaks.”

“”The study indicates that nondirective meditation allows for more room to process memories and emotions than during concentrated meditation,” says Svend Davanger, a neuroscientist at the University of Oslo, and co-author of the study.”

“Social isolation has been recognized as a major risk factor for mobidity and mortality in humans for more than three decades. The brain is the key organ of social connections and processes, however, and hte same objective social relationships can be experienced as caring and protective or as exploitive and isolating. We have provided evidence that the perception of social isolation (i.e. loneliness) impacts the brain and behavior and is a risk factor for broad based morbidity and mortality….”

"Am I so beautiful that you've no words left?" -- Midna

“Am I so beautiful that you’ve no words left?” — Midna

Here is what I am reading today:

“Dogs first surprised cognition researchers when scientists showed that the animals readily follow a human’s pointing finger or gaze to find food. Both wolves, dogs’ closest relative, and chimpanzees, our near-cousin, have trouble doing this. Now, scientists have raised the dogs-only bar: The canines can also use the sound of a human voice alone to find that tasty treat. Researchers carried out the auditory test on adult dogs and 8- to 14-week-old puppies as their owners watched.”

“Liverpool Psychologist, Dr Georg Mayer , explained: “This suggests that the correlated brain patterns were the result of using areas thought to be involved in language processing. Therefore we can assume that musical training results in a rapid change in the cognitive mechansims utilised for music perception and these shared mechanisms are usually employed for language.””

“Laura Freberg, a psychologist at California Polytechnic State University and Google Glass owner, believes society will develop a new etiquette for using head-mounted technology in social situations, but it will take time. People will need to work out where and when the use of such devices is acceptable to others.

“I walked into the restroom and was like, ‘oh my gosh… I’m going to make people really uncomfortable’,” she says. “It’s a learning process for the person who is wearing it as much as it is for the people around you. I think developing good manners will help us work through a lot of these problems.””

When Brent Williams got to RadioShack that day in the spring of 2012, he knew exactly what he was looking for: a variable resistor, a current regulator, a circuit board, and a 9-volt battery. The total came to around $20. Williams is tall and balding, with wire-rim glasses that make him look like an engineer, which he is. He directs a center on technology in education at Kennesaw State University and is the kind of guy who spends his free time chatting up people on his ham radio or trying to glimpse a passing comet with his telescope. But this project was different.”

“The problem with figuring out how nerve cells work in the eye, of either mice or humans, is the inability to watch what happens in action—everything is too tiny and intricate. To get around that problem, researchers have been building three dimensional models on computers. But even that gets untenable when considering the complexity and numbers of nerves involved. That’s where the EyeWire gamers came in….”

“So cognitive scientist Andreas Lind and his colleagues at Lund University in Sweden wanted to see what would happen if someone said one word, but heard themselves saying another. “If we use auditory feedback to compare what we say with a well-specified intention, then any mismatch should be quickly detected,” he says. “But if the feedback is instead a powerful factor in a dynamic, interpretative process, then the manipulation could go undetected.””

“The unidentified patient is a health care professional who had been working in Saudi Arabia. Saudi Arabia is the epicenter of the viral outbreak of MERS, federal health officials said Friday.

MERS has sickened hundreds of people in the Middle East, and kills about a quarter of the people who contract the virus, Dr. Anne Schuchat, director of National Center for Immunizations and Respiratory Diseases at the U.S. Centers for Disease Control and Prevention, said during a Friday news conference.”

My daughters Kristin and Karen have been wonderful research collaborators over the years. One colleague quipped ,"If I knew how reliable a stats and communication person would be, I would have spawned some year's ago!"

My daughters Kristin and Karen have been wonderful research collaborators over the years. One colleague quipped ,”If I knew how reliable a stats and communication person would be, I would have spawned some year’s ago!”

Here is what I am reading today:

“The Defense Advanced Research Projects Agency (DARPA) is forging ahead with a four-year plan to build a sophisticated memory stimulator, as part of President Barack Obama’s $100 million initiative to better understand the human brain.

The science has never been done before, and raises ethical questions about whether the human mind should be manipulated in the name of staving off war injuries or managing the aging brain.”

“The study was carried out by Christian Scharinger and Ulrich Rabl, under the supervision of Lukas Pezawas at the Department of Biological Psychiatry, University Department of Psychiatry and Psychotherapy at the MedUni Vienna, in collaboration with groups from the special research division SFB-35 and other institutions at the MedUni Vienna, as well as international cooperation partners (Technical University of Dresden, Central Institute for Mental Health, Mannheim). Alongside other colleagues from the University Department of Psychiatry and Psychotherapy, the MedUni Vienna’s Centre of Excellence for High Field MR, Clinical Institute of Laboratory Medicine and Institute of Pharmacology were also involved in the study.”

“”When we made detailed comparisons, we found that about a third of people with AgCC would meet diagnostic criteria for an autism spectrum disorder in terms of their current symptoms,” says Paul, who was the founding president of the National Organization for Disorders of the Corpus Callosum.

The research was done in the laboratory of Ralph Adolphs, Bren Professor of Psychology and Neuroscience and professor of biology at Caltech and a coauthor of the study. The team looked at a range of different tasks performed by both sets of patients. Some of the exercises that involved certain social behaviors were videotaped and analyzed by the researchers to assess for autism. The team also gave the individuals questionnaires to fill out that measured factors like intelligence and social functioning.”

“Based solely on genetic markers, GPS could place individuals within their country of origin 83% of the time. Half of the subjects were pinpointed within 87 km of their reported point of origin. For instance, all female subjects from the mountain commune of San Basilio, Sardinia, were placed in their original village (inset).”

“Dr Rob Waterland of Baylor College of Medicine in Houston, who conducted the epigenetic analyses said: “We selected these gene regions because our earlier studies in mice had shown that establishment of DNA methylation at metastable epialleles is particularly sensitive to maternal nutrition in early pregnancy.”

The authors note that their study was limited by including only one blood sampling point during early pregnancy, but estimates of pre-conception nutrient concentrations were calculated using results from non-pregnant women sampled throughout a whole calendar year. The authors also plan to increase the sample size in further studies.”

Simpson and colleagues describe the monkeys as being more communicative when they saw the caregivers, that is, making facial gestures more frequently after receiving oxytocin than they did after receiving the saline. The monkeys were more likely to engage in lip smacking than tongue protrusion, but were more likely still to engage in either of these gestures after oxytocin than after the saline. Although on average monkeys exposed to oxytocin gestured more than after exposure to saline, there were differences in the frequency of gesturing among the individual monkeys. Monkeys who were more likely than their peers to gesture at caregivers in the first week of life (which the researchers termed strong imitators) gestured more frequently after oxytocin than did peers who were not as likely to gesture in the first week.”

Here’s what we are reading today:

“Moreover, animals with the most varied diets showed the most self-restraint, according to the study published April 21 in the journal of the Proceedings of the National Academy of Sciences.

“The study levels the playing field on the question of animal intelligence,” said UC Berkeley psychologist Lucia Jacobs, a co-author of this study and of its precursor, a 2012 paper in the journal, Animal Cognition.”

“It’s a little-known fact that MRI (magnetic resonance imaging) machines can show you the inside of an apple just as it can show you the insides of your brain.

MRI technologist Andy Ellison used his professional training and access to advanced medical technology to capture cross-sections of various types of fruits and vegetables just like he normally would a human brain. From corn to starfruit, Ellison left no organic matter untouched.”

“”The more we study the club of this tiny crustacean, the more we realize its structure could improve so many things we use every day,” said David Kisailus, a Kavli Fellow of the National Academy of Science and the Winston Chung Endowed Chair of Energy Innovation at the UC Riverside’s Bourns College of Engineering.

The peacock mantis shrimp, or stomatopod, is a 4- to 6-inch-long rainbow-colored crustacean with a fist-like club that accelerates underwater faster than a 22-calibur bullet. Researchers, led by Kisailus, an associate professor of chemical engineering, are interested in the club because it can strike prey thousands of times without breaking.”

“Kazue Hasimoto-Torii, PhD, Principal Investigator of the Center for Neuroscience, Children’s National Health System, and a Scott-Gentle Foundation investigator, is lead author of the paper. Torii was previously at Yale, whose researchers were co-authors in the report. The research was funded primarily through National Institutes of Health grants.”

“People aren’t the only ones who raise their voices at each other; fish can shout, too. After catching some blacktail shiners—little minnows characterized by a big black splotch on their tail fin—fishery biologists placed them in tanks equipped with underwater speakers to see if noisy conditions affect communication. While females of Cyprinella venusta (pictured) don’t make noise, males produce two types of sound: growls and knocks. The growl is similar to a cat’s purr and is made when courting a female, while the knocks are more like popping sounds, typically made when males are fighting or defending their nests from another male.”

Neurobiologist Margaret Livingstone of Harvard Medical School in Boston and her colleagues had already taught three rhesus macaques (Macaca mulatta) in the lab to associate the Arabic numbers 0 through 9 and 15 select letters with the values zero through 25. When given the choice between two symbols, monkeys reliably chose the larger to get a correspondingly larger number of droplets of water, apple juice, or orange soda as a reward. To test whether the monkeys could add these values, the researchers began giving them a choice between a sum and a single symbol rather than two single symbols. Within 4 months, the monkeys had learned how the task worked and were able to effectively add two symbols and compare the sum to a third, single symbol.”

“Reactive oxygen species are important intracellular signaling molecules, but their mode of action is complex: In low concentrations they regulate key aspects of cellular function and behavior, while at high concentrations they can cause “oxidative stress”, which damages organelles, membranes and DNA. To analyze how redox signaling unfolds in single cells and organelles in real-time, an innovative optical microscopy technique has been developed jointly by the teams of LMU Professor Martin Kerschensteiner and TUM Professor Thomas Misgeld, both investigators of the Munich Cluster for Systems Neurology (SyNergy).”

“New research published today out of the University of Calgary’s Hotchkiss Brain Institute (HBI) uncovers a mechanism to promote growth in damaged nerve cells as a means to restore connections after injury. Dr. Doug Zochodne and his team have discovered a key molecule that directly regulates nerve cell growth in the damaged nervous system. His study was published in the prestigious journal Nature Communications, with lead authors Drs. Kim Christie and Anand Krishnan.”

“Professor Richard Sharpe said: “There is increasing evidence that a mother’s diet, lifestyle and exposure to drugs and chemicals can have a significant impact ontestosterone levels in the womb. We need a better grasp of these factors so that we can give reliable advice to pregnant women to protect the health of her unborn child.””
