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.

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.

From New Scientist:

THE Nobel prize system needs an overhaul. That's the conclusion of a group of scientists brought together by New Scientist to debate the future of the prizes.

In a letter to the Nobel Foundation, published on newscientist.com on 30 September, the group suggests that the foundation should introduce prizes for the environment and public health, and reform the existing medicine prize. "These suggestions will enable the prizes to remain influential for another hundred years," the group says.

Weird, Rare Clouds And The Physics Behind Them

From Wired Science:

In August, we posted a photograph of some odd, rare clouds known as Morning Glory clouds without providing an explanation for how they form. In response to reader interest, we followed up with meteorologist Roger Smith of the University of Munich, who has studied their formation.

“Over the years we’ve developed a good understanding of them,” Smith said. “It’s no longer a mystery, but still very spectacular.”

From The Independent:

New images of our galaxy today showed a small part of the milky way in a new light.

A British scientist involved in obtaining the pictures said they showed the galaxy in "a very turbulent process", constantly forging new generations of stars.

The images were produced by the Herschel Space Observatory using, for the first time, the UK-led Spire camera in tandem with the satellite's other camera, Pacs.

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.

Russia Extends Human Cloning Ban

From RIA Novosti:

MOSCOW, October 2 (RIA Novosti) - Russia has decided to extend a moratorium on human cloning that expired two years ago by five years, the health and social development minister said on Friday.

Tatyana Golikova said the moratorium, which ended on June 23, 2007, "only applies to human cloning."

It was not entirely clear why it was not prolonged at the time or whether any human cloning experiments had been carried out in Russia during the past two years.

From Science Daily:

ScienceDaily (Oct. 3, 2009) — In 1980, Luis Alvarez and his collaborators stunned the world with their discovery that an asteroid impact 65 million years ago probably killed off the dinosaurs and much of the the world's living organisms. But ever since, there has been an ongoing debate about how long it took for life to return to the devastated planet and for ecosystems to bounce back.

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.

From ABC News (Australia):

The NASA Viking 2 probe, which landed on Mars in 1976, may have come within centimetres of finding water three decades before it was eventually found.

The finding could result in scientists re-evaluating data collected by the spacecraft, which was sent to look for signs of life on the red planet.

"Oh my, oh my," says retired Viking scientist Dr Patricia Straat.

Polar Bear Cub Hitches A Ride

From The BBC:

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.

What Does A Star Sound Like?

From Popular Science:

Observing a star up close (putting aside for a moment how you’d get there or withstand its heat) is probably like sitting beside an enormous silent fire. 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.

From Air & Space Smithsonian:

In the 1950s Harvey Allen solved the problem of atmospheric entry. But first he had to convince his colleagues.

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. But it was all wrong.

Protein That Enhances Long-term Memory By Controlling Rest Intervals Identified

From Science Daily:

ScienceDaily (Oct. 3, 2009) — As most good students realize, repeated studying produces good memory. Those who study a lot realize, further, that what they learn tends to be preserved longer in memory if they space out learning sessions between rest intervals. Neuroscientists at Cold Spring Harbor Laboratory (CSHL) have now discovered how this so-called "spacing effect" is controlled in the brain at the level of individual molecules.

Only 3 Countries In The World Have More People Than Facebook

From Pingdom:

The Facebook phenomenon continues. Yesterday Facebook announced that it has a whopping 300 million active users.

Three. Hundred. Million. Users.

For some perspective on how huge that is:

* There are only THREE countries in the entire world that have a population of more than 300 million. Those are China (1.33 billion), India (1.17 billion) and USA (307 million).
* Russia has a population of 142 million. That’s not even half of Facebook’s user base.
* Facebook has almost five times as many users as the entire population of the UK (62 million).

From Science Daily:

ScienceDaily (Oct. 3, 2009) — A research team led by Lucas Pelkmans at ETH Zürich has managed to decipher a well-known phenomenon that had, until now, remained unexplained: why cells of the same type can react differently, and what the reason for this is.

The properties of a cell population determine the different cell activities observed in cells of the same type. This is the conclusion drawn by a research team lead by Lucas Pelkmans, professor at the Institute for Molecular Systems Biology at ETH Zürich.
