(PhysOrg.com) -- An international team of scientists have discovered an ‘ordinary’ black hole in the 12 million light year-distant galaxy Centaurus A.
One comment below the article - What a beautiful thing...yes, the photo could have been larger, but, the majesty of nature, the scope of naturallly occuring phenomenon in space and time...the physics, the math, the chemistry...we will need a few more Einsteins, Curies, Steinmetz, Paulings, to ever use or understand it all, but...there IT IS, beckoning to us...WE have unlimited Vistas. We do not have 2 fear running out of things that beckon & embrace us unto greatness...the vastness of the unknown, is our playground.This playground even extends into our most basic elements of life's biology: we still do not know what life is, but, in that mystery is the marvel: It really is the Undiscovered Country where we find the compeltion and fulfillment that speaks to the marvel of thought! What are we, to the Universe that ina twinkling of Geological time we know so much and yet are not full? We beg to know more and Nature can't wait for us to grow up and learn it all. We bit that fruit a moment ago...eat more, faster...
A team of experts showcase breakthroughs in technology and engineering. Mark Evans fuses his brain with a computer in Switzerland, while Kathy Sykes heads to San Francisco to experience the future of transport in a driverless car.
“We wanted to know if making you remember that painful event would also lead to the disruption of related memories,” Nader says. “Or could we alter just that one association?” The answer was clear. By injecting a protein synthesis inhibitor before the rats were exposed to only one of the sounds—and therefore before they underwent memory reconsolidation—the rats could be “trained” to forget the fear associated with that particular tone. “Only the first link was gone,” Nader says. The other associations remained perfectly intact. This is a profound result. While scientists have long wondered how to target specific memories in the brain, it turns out to be remarkably easy: All you have to do is ask people to remember them.
At a global level, the gap between wealthy nations and poorer nations continues to close. Across the board, we are living longer, wealthier, healthier lives. Certainly, there are still millions of people living in dire, back-breaking poverty, but using almost every quality-of-life metric available—access to goods and services, access to transportation, access to information, access to education, access to life-saving medicines and procedures, means of communication, value of human rights, importance of democratic institutions, durable shelter, available calories, available employment, affordable energy, even affordable beer—our day-to-day experience has improved massively over the past two centuries.
A frenzied desire to be first inspired Darwin and Einstein to bursts of creativity.
Ian McEwan reflects on originality and collaboration
In 1858 and 1915, Darwin and Einstein, driven in part by the somewhat ignoble or worldly ambition to be first, redirected not only the course of science, but redefined our sense of ourselves. These twin revolutions, barely 60 years apart, represent the most profound as well as the most rapid shift and dislocation in human thought that has ever occurred.
When faced with life-or-death situations, bacteria — and maybe even human cells — use an extremely sophisticated version of "game theory" to consider their options and decide upon the best course of action, scientists reported here today.
The remains of what may be a previously unknown human species living just 11,500 years ago are identified in southern China, although the science team behind the discovery is stopping short of a formal classification.
"We're trying to be very careful at this stage about definitely classifying them," said study co-leader Darren Curnoe from the University of New South Wales, Australia.
"The question of free will touches nearly everything we care about. Morality, law, politics, religion, public policy, intimate relationships, feelings of guilt and personal accomplishment—most of what is distinctly human about our lives seems to depend upon our viewing one another as autonomous persons, capable of free choice. If the scientific community were to declare free will an illusion, it would precipitate a culture war far more belligerent than the one that has been waged on the subject of evolution."

Researchers publish the complete genome of the 5,300-year-old Oetzi, the "Iceman", revealing his eye colour, blood type and a number of his ailments.
I had my genome analysed 2 years ago as part of the National Geographic research program and they told me I'm related to Oetzi, not sure how, but with improving DNA testing, I'm going to send mine off again. They also told me that three of the four women who are ancestors of all Jewish people are also my ancestors.
USA TODAYStudy: New children's books lack reference to nature, animals The proportion of images where the built environment was the primary environment rose throughout the period studied.
Psychologist Susan Linn, author of The Case for Make Believe, says the research supports growing concerns about kids' lack of connection with nature. "Time in green space is essential to children's mental and physical health. And the health of the planet depends on a generation of children who love and respect the natural world enough to protect it from abuse and degradation."
Prominent atheist Richard Dawkins has been hit by fresh scandal today after it emerged his ancestors were single-celled organisms who metabolised sulphur.
New findings have shown that the outspoken atheist is the direct descendent of a primordial soup-dwelling thermophile – a particular variant of extremophile which clung to hydrothermic vents just 3.5 billion years ago.
