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.

Paleo-Case Solved: Ancient Sharks Fed on Giant Reptile

This artist's rendering reveals what an ancient marine reptile called a plesiosaur discovered in Antarctica may have looked like. The plesiosaur described in a forthcoming issue of the Journal of Vertebrate Paleontology, though not the same species, also sported four fins and a long neck. Analyses of shark teeth embedded in the reptile's bones suggest a feeding frenzy of sorts once the reptile died. Credit: Nicolle Rager, National Science Foundation.

From San Francisco Chronicle:

Amazon.com has agreed that it won't remove e-books from U.S. users' Kindle electronic readers without their permission, as part of a proposed settlement of a lawsuit over the online retailer's deletion of a George Orwell novel from a high school student's e-reader.

Justin D. Gawronski, a 17-year-old student in Shelby Township, Michigan, sued Amazon after it erased copies of the Orwell works "1984" and "Animal Farm" from customers' Kindles in July. Gawronski's suit claimed removing "1984" from his Kindle made electronic notes he had taken on the e-reader useless. He was reading the book for an advanced placement course in which he had to turn in "reflections" on each 100 pages of text.

Sheets of green light shimmer in front of the stars, waxing and waning, as electrons from the solar wind rain down through Earth’s atmosphere, colliding with atoms and creating the aurora. Here, watching the light show under a zillion stars, I get a strong, almost physical awareness of being on a planet—a planet orbiting a star and connected to it, despite the 93 million miles of space separating them.

Sedatives May Slow Recovery From Trauma

Benzodiazepines may not be the answer for soldiers suffering stress from the horrors of war (Image: Sipa Press/Rex Features)

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.

The US Department of Veterans Affairs says it will consider this and other studies when preparing new guidelines on treatments for post-traumatic stress disorder (PTSD). 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").

Flirting with an attractive woman really does make men feel good, scientists find, as they discover it causes a surge in health-giving hormones.

Researchers found that just being in the presence of a pretty member of the opposite sex causes a temporary boost in levels of testosterone and cortisol – both hormones associated with alertness and wellbeing.

However hanging around with other men has the opposite affect – reducing the levels of both substances in the body.

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.

New Ancient Fungus Finding Suggests World's Forests Were Wiped Out In Global Catastrophe

From Science Daily:

ScienceDaily (Oct. 2, 2009) — Tiny organisms that covered the planet more than 250 million years ago appear to be a species of ancient fungus that thrived in dead wood, according to new research published October 1 in the journal Geology.

The researchers behind the study, from Imperial College London and other universities in the UK, USA and The Netherlands, believe that the organisms were able to thrive during this period because the world's forests had been wiped out. This would explain how the organisms, which are known as Reduviasporonites, were able to proliferate across the planet.

Alvin was just big enough to hold her, the submersible’s pilot, and Penn State colleague Chris House. Fortunately, as Beal peered out of Alvin’s plate-sized portholes during her descent, her claustrophobia quickly gave way to pure, unalloyed exhilaration.

Apple’s Tablet Could Be Print Industry’s Lifeboat

The more you think about it, the more obvious it is that an Apple tablet would specialize in reviving dead-tree media (i.e., newspapers, magazines and books).
