Ulkonäköön liittyvät ennakkoluulot kumpuavat aivojen alkukantaisista kerroksista - Rasismi - Elämä Ulkonäköön liittyvät ennakkoluulot kumpuavat aivojen alkukantaisista kerroksista 1. Ennakkoluulojen juuret ovat usein aivojen alkukantaisissa kerroksissa. Ihminen saattaa tiedostamattaan ottaa enemmän etäisyyttä nähdessään erivärisen ihmisen, vaikkei ajattelisikaan rasistisesti. Empatiakaan ei ole tasapuolista: aivot reagoivat vahvemmin samankaltaiseksi koetun ihmisen kipuun. 2. 3. 4.
Study Examines Scale of Gene Mutations in Human Neurons A single neuron in a normal adult brain likely has more than a thousand genetic mutations that are not present in the cells that surround it, according to new research from Howard Hughes Medical Institute (HHMI) scientists. The majority of these mutations appear to arise while genes are in active use, after brain development is complete. “We found that the genes that the brain uses most of all are the genes that are most fragile and most likely to be mutated,” says Christopher Walsh, an HHMI investigator at Boston Children's Hospital who led the research. It's not yet clear how these naturally occurring mutations impact the function of a normal brain, or to what extent they contribute to disease. Cells of many shapes, sizes, and function are intimately intertwined inside the brain, and scientists have wondered for centuries how that diversity is generated. The scientists isolated and sequenced the genomes of 36 neurons from healthy brains donated by three adults after their deaths.
Trautner-Borland--Academic_Integrity.pdf Healthy News and Information By Jackie Clay-Atkinson Year after year we start seeds, till the ground, plant, weed, harvest, then tear it all out at the end of the season. It’s a lot of work, no doubt. But there are some plants you can plant once that will produce a lifetime of food after they are established. Asparagus Asparagus is perhaps the easiest, most commonly grown permanent crop. When you plant asparagus from seed, it usually takes four years before you get an appreciable harvest of asparagus from your row or bed. Preparing your asparagus beds for planting is quite important because your asparagus will be there for a long, long time. I dig a wide furrow 18 inches deep. As the asparagus sends out spears, gently add more soil and compost to the trench until it is even with the soil level. The next year you’ll be able to widen your harvesting window to about 2-3 weeks, again only picking the fattest spears. Chives Chives are one of the easiest and most useful of all small garden permanent plantings. Horseradish

Old rat brains rejuvenated and new neurons grown by asthma drug It’s as good as new. An asthma drug has rejuvenated rat brains, making old rats perform as well as young rats in tests of memory and cognition. The drug also encouraged the birth of new brain cells. As we get older, most of us will experience some kind of brain degeneration. To tackle both problems in one go, Ludwig Aigner at Paracelsus Medical University Salzburg in Austria and his colleagues targeted a set of receptors in the brain that, when activated, trigger inflammation. High numbers of these receptors are found in areas of the brain where neurons are born, suggesting they might also be involved in this process, too. A drug called montelukast (Singulair), regularly prescribed for asthma and allergic rhinitis, blocks these receptors, so Aigner and his colleagues tried it on young and old rats. Escape plan The rats took part in a range of learning and memory tests. By the end of their six-week drug regime, though, old animals performed as well as their younger companions. Real ageing
AVID Sociology Instruction I Created A Mirrored Ziggurat To Connect The Earth And Sky In Sydney In this installation I have been inspired by the pyramidal structure of Ziggurat, a common form of temple in ancient Mesopotamia, attempting to connect earth and sky, so humans could be nearer to god. The Mirrored Ziggurat acts as a staircase, which seeks to connect nature with human beings and to create a union of ancient history and today’s world. This installation offers a transformative view of the self. The Mirrored Ziggurat has seven levels that represent seven heavens. For me, mirrors amplify this paradise, giving light; an important mystical concept in Persian Culture, and a medium creating an optical illusion.

The Brain-Gut Axis, Part 1 – A Paradigm Shift In Neuroscience Traditional Eastern medicine has long acknowledged the importance of the gut. But evidence-based medicine, colloquially called Western medicine despite being practiced all over the world, has long disregarded a possible link between the brain and the gut – until recently, because a paradigm shift in neuroscience is now taking place. Both Ayurveda (the traditional Hindu medicine) and Traditional Chinese Medicine (TCM) attribute a tremendous impact to the digestive system in all health and disease, and underline its strong connection to the mind. Ayurveda states that the health of the digestive system is the single most important determinant of health and well–being. Likewise, TCM recognizes the digestive system as the center of all bodily functions and strongly links it to the brain. Arguably, the connection between the gut and the brain is somewhat embedded in our collective unconscious. The gut microbiota (the microbe ecosystem) has become our body’s superstar lately.

Poverty Games, Part 5: Inequality Monopoly | Active Learning in Political Science © Some of my sociologist friends turned me onto a common game they use in their field to teach about social class and inequality: Inequality Monopoly (also called Modified Monopoly, Development Monopoly, or Stratified Monopoly). The basic idea is to have students play a classic game of Monopoly (8 students to a board, multiple boards as needed) but with a twist: starting resources, salary, jail, and other effects of the game change based on which ‘social class’ you are randomly assigned at the beginning. So the upper class player may start with $2500 and a couple of hotels they can place on the first property they land on, while the middle class starts with $1500 and a house, the working class $1000 and lower class $500. Salaries change too; only the upper class gets the full $200 for passing Go. You can also speed up the game by simply distributing property in advance; some of the rule sets below have ideas on ways to do this. Resources to Play the Game: Poverty Games Pt 3: Free Rice
UK Is Testing Roads That Charge Electric Cars As They Drive Imagine never having to pull over to fuel your car. This is exactly what Highways England is planning to implement for drivers of electric vehicles. Automobiles would be fitted with wireless technology and then driven on roads with special electromagnetic field generating equipment buried underneath. Trials will run for 18 months before a decision is made to move the project to public roads. This is not the first time such technology sees the light of day: in 2013, the South Korean town of Gumi switched on a 12km (7.5 miles) route that allows special buses to be charged with similar technology. “Vehicle technologies are advancing at an ever increasing pace and we’re committed to supporting the growth of ultra-low emissions vehicles on England’s motorways and major A roads,” wrote Highways England chief highways engineer, Mike Wilson.

Moni mies kokee homouden uhkana – vieroksuja yrittää puolustaa asemaansa - Homoseksuaalisuus - Tiede Moni mies kokee homouden uhkana – vieroksuja yrittää puolustaa asemaansa Parikymmentä vuotta sitten tutkijat tekivät Yhdysvalloissa suorasukaisen kokeen, jolla he testasivat tunnettua teoriaa homofobiasta. Sen mukaan homoja karsastavat miehet tuntevat tiedostamatonta seksuaalista kiinnostusta omaan sukupuoleensa, mutta torjuvat kielletyn halunsa ja siksi kammoksuvat sitä myös muissa. Ajatus on peräisin psykoanalyysin luojalta Sigmund Freudilta. Georgian yliopiston tutkija Henry Adams ja hänen työtoverinsa testasivat teoriaa ryhmällä opiskelijamiehiä. Ensin tutkijat selvittivät opiskelijoiden asennetta homoihin. Freud olisi ollut tyytyväinen tulokseen. Paisuvaiskudoksen pullistuminen voi kuitenkin kertoa myös muusta kuin kiihottumisesta. Homovastaiset opiskelijat ehkä pelkäsivät kiihottumista ja sen näkymistä tutkijoiden mittareissa, ja juuri se pisti liikettä nivusiin. Toiset tutkimukset viittaavat siihen, että homoseksuaalisuuden torjunta on sitä miltä se näyttää: vieroksuntaa.
Researchers Create Wireless Implantable Device That Can Stimulate Neurons In a Stanford experiment, this mouse transmitting energy from its body, it powers up an implantable device to deliver light stimulation to its own leg nerves.(Photo : Stanford University) Researchers from Stanford University developed a wireless device combining optogenetics with wireless technology, paving the way for a new breed of implants. Optogenetics utilizes light to control brain activity. Traditionally though, light is delivered and nerves are controlled through a fiber optic cable attached to the head of a mouse. Ada Poon is renowned for creating small, wireless implantable devices but she didn't realize how badly her abilities were sought-after in optogenetics until she went to a neural engineering workshop. Poon and colleagues want to clarify though that optogenetics only affects nerves that have been particularly prepared to house light-responsive proteins. The researchers already had a light source but the problem was powering the device without losing power efficiency.
