A Momentary Flow

Updating Worldviews one World at a time

All human beings (and their brains) have to cope with the fact that their five senses gather more information than even the magnificent human brain is able to process. To put this another way: we need to be able to ignore a lot of what is happening around us — the smell of pizza baking, the sound of the cat meowing, or the sight of birds flying outside the window — if we are going to focus our attention and concentrate on what we are doing (in your case, for example, reading this book). Our ability to filter out unnecessary stimuli and focus our attention is mediated by brain mechanisms in regions known as the thalamus and the reticular activating system.

The Relationship Between Creativity and Mental Illness | Brain Pickings

Many personality characteristics of creative people … make them more vulnerable, including openness to new experiences, a tolerance for ambiguity, and an approach to life and the world that is relatively free of preconceptions. This flexibility permits them to perceive things in a fresh and novel way, which is an important basis for creativity. But it also means that their inner world is complex, ambiguous, and filled with shades of gray rather than black and white. It is a world filled with many questions and few easy answers. While less creative people can quickly respond to situations based on what they have been told by people in authority — parents, teachers, pastors, rabbis, or priests — the creative person lives in a more fluid and nebulous world. He or she may have to confront criticism or rejection for being too questioning, or too unconventional. Such traits can lead to feelings of depression or social alienation. A highly original person may seem odd or strange to others. Too much openness means living on the edge. Sometimes the person may drop over the edge… into depression, mania, or perhaps schizophrenia.

A new approach in the search for extraterrestrial intelligence: targeting alien polluters
-
Humanity is on the threshold of being able to detect signs of alien life on other worlds. By studying exoplanet atmospheres, we can look for gases like oxygen and methane that only coexist if replenished by life. But those gases come from simple life forms like microbes. What about advanced civilizations? Would they leave any detectable signs? They might, if they spew industrial pollution into the atmosphere. New research by theorists at the Harvard-Smithsonian Center for Astrophysics (CfA) shows that we could spot the fingerprints of certain pollutants under ideal conditions. This would offer a new approach in the search for extraterrestrial intelligence (SETI). “We consider industrial pollution as a sign of intelligent life, but perhaps civilizations more advanced than us, with their own SETI programs, will consider pollution as a sign of unintelligent life since it’s not smart to contaminate your own air,” says Harvard student and lead author Henry Lin. “People often refer to ETs as ‘little green men,’ but the ETs detectable by this method should not be labeled ‘green’ since they are environmentally unfriendly,” adds Harvard co-author Avi Loeb. The team, which also includes Smithsonian scientist Gonzalo Gonzalez Abad, finds that the upcoming James Webb Space Telescope (JWST) should be able to detect two kinds of chlorofluorocarbons (CFCs)—ozone-destroying chemicals used in solvents and aerosols. They calculated that JWST could tease out the signal of CFCs if atmospheric levels were 10 times those on Earth. A particularly advanced civilization might intentionally pollute the atmosphere to high levels and globally warm a planet that is otherwise too cold for life. There is one big caveat to this work. JWST can only detect pollutants on an Earth-like planet circling a white dwarf star, which is what remains when a star like our Sun dies. That scenario would maximize the atmospheric signal. Finding pollution on an Earth-like planet orbiting a Sun-like star would require an instrument beyond JWST—a next-next-generation telescope.

When Will Robots Take Over the World?

Jul 17, 2014 | 2-part series
Kasia Cieplak-Mayr von Baldegg, Sam Price-Waldman, Paul Rosenfeld

At this year’s Aspen Ideas Festival, we asked a group of futurists, technology experts, and artists to predict the future of robotics. So, will machines revolt against humans? Maybe not, but as Duke University professor Missy Cummings explains, they may have already won. “We don’t even realize where robots are in our world,” she says.

Why bystanders are reluctant to report a violent crime or aid a victim, and how they can be taught to step up and help - Bethesda in the state of Maryland is the kind of safe, upscale Washington DC suburb that well-educated, high-earning professionals retreat to when it’s time to raise a family. Some 80 per cent of the city’s adult residents have college degrees. Bethesda’s posh Bradley Manor-Longwood neighbourhood was recently ranked the second richest in the country. And yet, on 11 March 2011, a young woman was brutally murdered by a fellow employee at a local Lululemon store (where yoga pants retail for about $100 each). Two employees of the Apple store next door heard the murder as it occurred, debated, and ultimately decided not to call the police. If the attack had occurred in poor, crowded, crime-ridden Rio de Janeiro, the outcome might have been different: in one series of experiments, researchers found bystanders in the Brazilian city to be extraordinarily helpful, stepping in to offer a hand to a blind person and aiding a stranger who dropped a pen nearly 100 per cent of the time. This apparent paradox reflects a nuanced understanding of ‘bystander apathy’, the term coined by the US psychologists John Darley and Bibb Latané in the 1960s to describe the puzzling, and often horrifying, inaction of witnesses to intervene in violent crimes or other tragedies.

India doctors remove 232 teeth from boy’s mouth
-
Doctors in India have extracted 232 teeth from the mouth of a 17-year-old boy in a seven-hour operation. Ashik Gavai was brought in with a swelling in his right jaw, Dr Sunanda Dhiware, head of Mumbai’s JJ Hospital’s dental department, told the BBC. The teenager had been suffering for 18 months and travelled to the city from his village after local doctors failed to identify the cause of the problem. Doctors have described his condition as “very rare” and “a world record”.
‘Small white pearls’ “Ashik’s malaise was diagnosed as a complex composite odontoma where a single gum forms lots of teeth. It’s a sort of benign tumour,” Dr Dhiware said. (via BBC News - India doctors remove 232 teeth from boy’s mouth)
