Humans sometimes perceive an inherently meaningless object such as a pattern, landscape or object as another object, one that has meaning. It's why alternative science proponents, the Jeffrey Smith's and Pete Myers of the world, believe in spirit photographs.
Some have even argued that pareidolia occurs in relatively low-level visual processing, and a new paper examines the relation between behavior when a face-like object is viewed and brain activity to reveal the level of visual processing at which face-likeness is recognized.
When a massive star consumes its nuclear fuel and collapses under its own gravity in a supernova explosion, it can result in a neutron star. These very dense objects have a radius of about 10 kilometers and yet are 1.5 times more massive than the Sun. They have very strong magnetic fields and are rapid rotators, with some neutron stars spinning more than 100 times per second round their axis.
In the 1980s, environmentalists and epidemiologists began to statistically correlate attention problems in children and lower scores on tests with flame retardants used in furniture, chemicals that had become popular because parents and fire departments wanted to prevent "flashover" events during house fires - explosions in closed rooms.
Large ecosystems bring stability, they insist. But that isn't really true. Instead, stability and diversity happen when the ecosystem is complex, not just because it is large. And he branching complexity of rivers are absolutely vital in affecting regional population stability and persistence in nature.
That doesn't mean you shouldn't encourage kids to try new things, but they are not going to end up unhealthy if they sat at the dinner table for an hour and still didn't eat that cabbage. And it debunks claims that picky eaters are at higher risk of being underweight, with poor growth, or being overweight.
Biologists learned this by placing food in a small translucent cylinder. The great tits that started pecking at the cylinder to get to the food failed the test as the behavior was considered an impulsive act. Those that, on the other hand, moved to an opening in the cylinder and thereby were able to access the food without pecking at the cylinder wall passed the test.
In a tweet, the coordinator for the science blog network of the British newspaper The Guardian announced that after eight years, the blog would be closing down.
We're told over and over again just how important science journalism is, usually by science journalists. Clearly, the public disagrees, and they have disagreed for a very long time. When newspapers began shrinking their news rooms many years ago, science reporters were among the first to go.
It is a cultural placebo that will make people feel like they did something important but it is meaningless. Instead, pollution is up because the world is wealthier, rich and relatively poor alike, than ever before.
Internet has changed my life more than any other "thing" around, and it has provided me with an enormous wealth - information, knowledge, simplification of otherwise difficult tasks, ease of access to data, solution to problems, connection with people all over the world, possibility to broadcast and publish. And entertainment, online gaming, music, videos, free porn, free movies, paid movies. I could go on, of course.
Democracies have better teeth than dictatorships, according to recent statistical correlation presented at the 96th General Session of the International Association for Dental Research (IADR) in London, held in conjunction with the IADR Pan European Regional (PER) Congress.
Obscured by thick clouds of absorbing dust, the closest supermassive black hole to the Earth lies 26 000 light-years away at the centre of the Milky Way. This gravitational monster, which has a mass four million times that of the Sun, is surrounded by a small group of stars orbiting around it at high speed. This extreme environment — the strongest gravitational field in our galaxy — makes it the perfect place to explore gravitational physics, and particularly to test Einstein’s general theory of relativity.
DESCRIBING THE SOLAR CYCLE
Biosphere reserves are sites hoping to couple conservation of biodiversity and human activity by promoting use of natural resources - which is a fuzzy term for fuzzy sustainable development practices.
The new biosphere reserves are (in alphabetical order of countries):
A new experiment shows that not only do dogs care if their owner is upset, they will overcome obstacles in a hurry to provide aid. The results in Learning&Behavior showed that dogs with strong bonds to their owners hurried to pushed through a door when they heard their person crying.
