I don't know why I have this idea of mid-19th century American silversmithing being clunky. This is some really nice stuff, some quite modern looking.

Like the title says - a demonstration of how to use Powerpoint to make 2D fractal images.

Jo Cameron gave birth to a child without needing pain killers, it "felt like a tickle". She has unintentionally injured herself due to not being able to feel the pain.

Scientists are also intrigued by Ms. Cameron’s extraordinarily low anxiety level. ... She cannot recall ever having felt depressed or scared.

In retrospect, she sees how her genetic disposition may have aided her at work. After years as a primary-school teacher, she retrained to work with people with severe mental disabilities. Erratic, aggressive behavior never riled her, she said.
...
But though having this mutation may sound like a dream, there are downsides. One is that she is quite forgetful; prone to losing her keys and her train of thought midsentence. The other is that she’s never felt the “adrenaline rush” that other people talk about, she said.

[quote] (E)ach sufficiently dense, compact object in space generates an invisible sphere around it which determines how the laws of physics behave with growing distance. This sphere is a theoretical concept to help us understand the difference between small and big scales, rather than an actual physical membrane.
According to our theory, within this bubble the laws of ordinary Newtonian gravity that we see in our solar system hold for objects interacting with the massive body at the centre. Outside the bubble, the theory suggests that the gravitational pull by the central object can be significantly enhanced – even though there is not more mass present.
The bubble size would be proportional to the mass of the central object.
...
To our big surprise, our theory allowed us to explain the stellar velocities in galaxies a lot better than with Einstein’s general relativity, which allows for dark matter to exist. So there may actually be less mysterious dark matter out there than we think – and maybe even none at all. [/quote]

Brazilian doctors are reporting the world’s first baby born to a woman with a uterus transplanted from a deceased donor.


Eleven previous births have used a transplanted womb but from a living donor, usually a relative or friend.
Living Wage Calculator

Quote: We developed a living wage calculator to estimate the cost of living in your community or region based on typical expenses. The tool helps individuals, communities, and employers determine a local wage rate that allows residents to meet minimum standards of living.
Quote: Glass sculptor Wesley Fleming creates life-size and anatomically correct sculptures of a variety of bizarre and well-known insects. The colorful creatures are small enough to balance gently on the tip of his finger, like a neon orange spider barely larger than his nail.
A battery has been design that runs on maltodextrin, a sugar.
The marine planarian, cuttlefish and Nile perch have one thing in common: in order to propel themselves, they use their fins to generate a continuous wave, which advances along their entire length. With this so-called undulating fin movement, the BionicFinWave also maneuvres through a pipe system (and at) the same time the autonomous underwater robot is able to communicate with the outside world wirelessly and transmit data

And really neat to watch too!
A researcher realizes that cancer cells share material via nanotubes. This might help cancer cells spread immunity to chemotherapy.
A report of one instance of a stolen identity being used to sell digital books of spam-style text for $555 a copy. The fake author gets 60% of the selling price. Even at that rate, the criminal managed to "earn" nearly $24,000 .
Founded in 2011, The Public Domain Review is an online journal and not-for-profit project dedicated to the exploration of curious and compelling works from the history of art, literature, and ideas.
In particular, as our name suggests, the focus is on works which have now fallen into the public domain, that vast commons of out-of-copyright material that everyone is free to enjoy, share, and build upon without restriction. Our aim is to promote and celebrate the public domain in all its abundance and variety, and help our readers explore its rich terrain – like a small exhibition gallery at the entrance to an immense network of archives and storage rooms that lie beyond.
We now know that all extant living creatures derive from a single common ancestor, called LUCA, the Last Universal Common Ancestor. It's hard to think of a more unifying view of life. All living creatures are linked to a single-celled creature, the root to the complex-branching tree of life. (...) They are able to trace LUCA to a simple prokaryotic creature (a single-celled bacterium with unprotected genetic material) that lived some 3 billion years ago. It must have been a very tough organism, able to survive in very extreme environments.
