Impulse control is associated with larger cognitively advanced animals like humans and other primates, but there are exceptions, like ravens. Now
a recent study shows that the great tit, a common European songbird, has a tremendous capacity for self-control - almost the same as chimpanzees.
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.
Bt modification in maize does not affect non-target beneficial microorganisms such as endophytes, according to a new study. This debunks some of the more obscure claims made by activists opposed to genetic engineering (suicides in India being the most bizarre.
Though evidence to-date shows we are the first advanced species, at least in our cosmic neighborhood, that doesn't mean it can't happen elsewhere. It is absolutely likely, because
according to one estimate there are as many as 700
million trillion terrestrial planets just in the observable universe.
The 2017 hurricane season was one of the most expensive in the Atlantic Ocean region. Hurricane Harvey hit in mid-August 2017, followed just a few weeks later by Hurricane Irma and Hurricane Maria in September. Each of these storms had winds in excess of 125 mph, with Irma up to 170 mph. Damage from totals for the hurricane season topped $282 billion.
American cities nationwide, riding a wave of populism brought about by media attention, are looking to ban straws, claiming they will save the planet doing so. Companies are naturally following suit - companies always will, because consumers pay the cost and if they are happy paying more while giving marketing departments something to promote it is an easy choice.
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.
There is very little I love more than the world wide web. No, seriously, I mean it.
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.
The effects predicted by Einstein’s general relativity on the motion of a star passing through the extreme gravitational field have been validated near the supermassive black hole in the center of the Milky Way.
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.
[Eleni Petrakou, Ph.D., is a physicist and an independent researcher, besides being a longtime follower of this blog. She now has a newsletter of her own; it is high S/N stuff - check it out here. After a past collaboration with the CMS experiment, she has recently become intrigued with the dynamics of the Sun, and she developed a model to try and predict the solar cycle, a 11-year variation of the activity of sunspots and solar flares whose origin is still debated. I asked her to describe the matter for this blog, and the text below is the result - TD]
DESCRIBING THE SOLAR CYCLE
The United Nations Educational, Scientific and Cultural Organization (UNESCO) branch of the United Nations has added 24 new sites to the World Network of Biosphere Reserves, bring the total number to 686.
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):
