Space entrepreneurs may hold fate of ISS - space - 23 August 2011. FOLLOWING the retirement of the space shuttle on 21 July, Americans couldn't have relished the thought of being dependent on Russian Soyuz rockets to get into space.

So when Russia's space agency Roskosmos said a week later that the 370-tonne International Space Station would be ditched in the Pacific Ocean in 2020, it must have seemed a hit below the belt. Crop circles. Cavity magnetron. Magnetron with section removed to exhibit the cavities.

Press reports are citing his resignation letter, To the Apple Board of Directors and the Apple Community:I have always said if there ever came a day when I could no longer meet my duties and expectations as Apple’s CEO, I would be the first to let you know. Unfortunately, that day has come.I hereby resign as CEO of Apple. Simplicity, Flexibility, Beauty!, Kiwi PyCon 2011, August 27-28, 2011, Wellington, New Zealand. 1.

1. Python: What can it do for us scientists?

Let me clarify.. Though Python is a programming language, in the recent years it has emerged as an extremely powerful tool for a variety of scientific applications: from data analysis to simulation and complex visualisations to interfacing with instruments. Let’s take a cyber tour of various web pages that illustrate the capabilities of Python in science. A basic tour Interactive infographics. NZPUG - New Zealand Python User Group.

Ruby, Python, and Science. David Jacobs has written a long blog post Ruby is beautiful (but I’m moving to Python).

Ruby, Python, and Science

Here’s my summary. Ruby is much better than Java, but the Ruby community is too focused on web development and the language has no scientific library. Programming for Scientists. November 17, 2009 – 6:34 pm Logo owned by the Python Software Foundation Rich has recently been considering switching to the Python programming language.

Programming for Scientists

Python for Scientists. In reaction to several colleagues asking about Python , I thought a webpage would be more useful than giving an exhaustive rundown on Python verbally. Python is a script based language that allows programmers/scientists to get their algorithms and functions working in little or no time. A large number of modules and wrappers are being built for Python, like RPy and Scipy , to allow advanced tools and faster processing speeds to be implemented. Plotting modules and programs are also in wide use among Python users. The wide array of tools that can be used for plotting provides great flexibility. To help users at all levels of Python familiarity, a list of handy links is given below in sections.

Today, August 27th, marks the grim anniversary of one of the most devastating volcanic eruptions in recorded history: the final explosion of the island of Krakatoa in 1883.

The eruption — and the tsunami that was generated by it — is estimated to have killed some one hundred thousand people, and it has even been speculated in Simon Winchester’s 2003 book Krakatoa: The Day the World Exploded that the eruption led to the political downfall of the Dutch Indonesian colonies. An 1888 lithograph representing the eruption of Krakatoa (source). On his Scientific American blog History of Geology, David Bressan has relayed some of the eyewitness accounts of the devastation. I thought it would be interesting to describe some of the first published scientific accounts of the event, and the struggle to understand it in its aftermath.

A new discovery has unlocked the secret story of lager beer’s South American origins, and is letting scientists piece together the genetic history of the domesticated microbe that keeps lager cool.

Brewing A Designer Beer

This final piece of the yeast’s genetic family tree could one day help brewers create custom-made designer brews with carefully selected characteristics. The modern-day lager yeast is a hybrid, born from an ancient hookup between a Saccharomyces cerevisiae--a popular ingredient for brewers and bakers--and another yeast that Diego Libkind and his company have identified and named Sacchyromyces eubyanus. They published their study in a recent issue of the Proceedings of the National Academy of Sciences. Room-temperature brown dwarf spied just 9 light-years off.

Scientists find weakness in deadly Ebola virus. CHICAGO (Reuters) - A protein that helps transport cholesterol inside cells may be a key to developing drugs to treat Ebola, a rare but lethal virus for which there are no known treatments, U.S. researchers said. Laboratory mice bred to produce low levels of this protein -- known Niemann-Pick C1 -- survived exposure to both Ebola, which causes a hemorrhagic fever, and its cousin, Marburg virus.

"This research identifies a critical cellular protein that the Ebola virus needs to cause infection and disease," said Sean Whelan of Harvard Medical School, who worked on one of two studies published on Wednesday in the journal Nature. "The discovery also improves chances that drugs can be developed that directly combat Ebola infections," Whelan said in a statement.

Ebola is one of the most deadly infections known, killing 90 percent of people infected by it.
