How Can a Pregnant Woman Get Pregnant Again?

Ian Hooton / Corbis

From Time Magazine:

An Indonesian woman gave birth to a 19-lb. 2-oz. baby behemoth on Sept. 24, but that was only the second weirdest pregnancy tale of the month. The strangest belongs to Julia Grovenburg, a 31-year-old Arkansas woman who has a double pregnancy. No, not twins — Grovenburg became pregnant twice, two weeks apart. Isn't that supposed to be impossible?

Almost. There have been only 10 recorded cases of the phenomenon, dubbed superfetation. In Grovenburg's case, she became pregnant first with a girl (whom she has decided to name Jillian) and then two weeks later with a boy (Hudson). The babies have separate due dates — Jillian on Dec. 24, Hudson on Jan. 10.

Fine Line Between Genius And Madness, Scientists Find

Vincent Van Gogh Photo: AP

From The Telegraph:

There is a fine line between genius and madness because they share the same genes, scientists have found.

Psychologists have discovered that creative people have a gene in common which is also linked to psychosis and depression.

They believe that the findings could explain why "geniuses" like Vincent van Gogh and Sylvia Plath displayed such destructive behaviour.

The gene, which is called neuregulin 1, plays a role in brain development but a variant of it is also associated with mental illnesses like schizophrenia and bipolar disorder.

The World's Growing Population Poses a Malthusian Dilemma

MALTHUSIAN DILEMMA: How to feed a human population expected to reach 9 billion by 2050 while also grappling with poverty as well as climate change, dead zones, biodiversity loss and other environmental ills? © iStockphoto.com / Tobias Helbig

From Scientific American:

Solving climate change, the Sixth Extinction and population growth... at the same time.

By 2050, the world will host nine billion people—and that's if population growth slows in much of the developing world. Today, at least one billion people are chronically malnourished or starving. Simply to maintain that sad state of affairs would require the clearing (read: deforestation) of 900 million additional hectares of land, according to Pedro Sanchez, director of the Tropical Agriculture and Rural Environment Program at The Earth Institute at Columbia University.

Lamp Runs On Human Blood

A lamp that uses blood to create light is meant to make people rethink how they use energy. The lamp contains luminol, a chemical that reacts with the iron in blood and creates a bright blue glow. Credit: Mike Thompson, http://www.miket.co.uk/

From Live Science:

What if, every time you wanted to switch on a light, you had to bleed? Would you think twice before illuminating the room, and in turn, using up energy?

That's the idea behind the blood lamp, invented by Mike Thomspon, an English designer based in The Netherlands. The lamp contains luminol – the same chemical forensic scientists use to check for traces of blood at a crime scence. Luminol reacts with the iron in red blood cells and creates a bright blue glow.
To use the lamp, you first need to mix in an activating powder. Then, you break the glass, cut yourself, and drip blood into the opening.

Arctic waters are at best chilly and at worst close to freezing.

Which may explain why a polar bear cub has recently been seen riding on the back of its mother as the bears swim across parts of the Arctic Ocean.

The cub then briefly rode her back as she clambered out of the icy water, a unique event photographed by a tourist.

Experts have rarely seen the behaviour, and they say the latest find suggests it may be a more common practice than previously thought.

Sounds—which are simply pressure variations in a medium such as air or water—can’t propagate in the vacuum of space, so the roiling surface of a star would make an impression on the eyes, but not the ears.

The cover of the March 22, 1952 issue of Collier’s magazine made an audacious promise. “Man Will Conquer Space Soon,” blared the headline, above a painting of a multi-stage rocket with engines blazing, bound for orbit. Designed by German rocket pioneer Wernher von Braun, whose name was still unknown to most Americans, the Collier’s spaceship was a sleek, needle-nosed beauty; its winged third stage would be piloted to a runway landing.

From New Scientist:

GIVING sleeping pills to soldiers and earthquake victims is common practice, yet it could be doing more harm than good. That's the suggestion from a study of traumatised rats, which seemed to show that the drugs suppressed the rodent's natural mechanisms for coping with trauma.

If their results are strong enough, it may recommend withholding sedatives in the aftermath of traumatic events. The findings are also throwing up new possibilities for preventing PTSD (see "Fight stress with stress").

Uncivilisation: The Dark Mountain Manifesto

From New Statesman:

We have, it seems, led the planet into the age of ecocide. Can civilisation survive the unavoidable environmental catastrophe? To stand a chance we will need cool heads, not fiery dreams.

During the past century empires crashed, new states foundered, utopian projects failed and entire civilisations melted down. Revolutionary change was the norm, as it has been throughout modern times. Yet today many of us assume our present way of life will last for ever, and any suggestion that it may be facing intractable difficulties is dismissed as doom-mongering. The result is that the precariousness of modern civilisation is underestimated and the impression that things can go on indefinitely, much as they do now is touted as hard-headed realism.
