New Look for Hydrogen Storage

A new technique for storing hydrogen has been proposed by scientists in Canada and Germany. The method, which involves storing the gas between layers of graphite just nanometres deep, could help in the quest for practical hydrogen-storage devices for fuel cells.
Graphite can store hydrogen better than other materials, such as carbon nanotubes, because it is cheap, non-toxic and easy to prepare.

According to their calculations, thin layers of graphite or graphene -- two-dimensional sheets of carbon atoms -- spaced between 6 and 7 Angstroms apart can store hydrogen at room temperature and moderate pressures of just 10 MPa.

KOffice 1.4 suite - The Real Complete Office Suite

The KDE Project released version 1.4 of its KOffice office productivity suite last week, adding two new applications, integrating support for new standards, improving interoperability with other office applications, and making a LiveCD version available.

The KOffice 1.4 suite claims to be "lightweight, yet feature-rich," and cooperative with Microsoft Office and OpenOffice.org. Also, though the integration will not be complete until the next release, KOffice 1.4 offers some support for OASIS's OpenDocument format.

The applications currently included in the KOffice 1.4 suite are:
KWord frame-based word processor
KSPread spreadsheet application
KPresenter presentation program
Kivio Visio-style flowcharting application
Karbon14 vector drawing application
Kugar report generator
KChart graph and chart drawing tool
KFormula formula editor
KPlato - A project management application
Krita (image manipulation application) and
Kexi (data management application).
Filters - (Many Import and Export Filters )

Mozilla extinguishes Firefox Security Flares.

The Mozilla Foundation updated the Firefox Web browser in order to patch a series of security vulnerabilities, including widely publicized browser spoofing issue and a frame-injection issue.

Mozilla has released Firefox 1.0.5 and plans to follow it with new versions of its Thunderbird email client and namesake browser application suite on Wednesday, said Chris Hofmann, Mozilla's director of engineering.

The Firefox update fixes 11 security issues discovered both by outside security researchers and from Mozilla's own Security Bug Bounty Program, which offers a $500 reward for reporting bugs.

Hofmann said that Mozilla knows of no exploits of the security vulnerabilities patched in Firefox 1.0.5.

Among the vulnerabilities plugged in Firefox 1.0.5 is a browser spoofing issue reported last month by security researcher Secunia. The spoofing vulnerability, which affected all major browsers, could aid scammers in successfully launching phishing attacks.

Verical Farming - The Right Choice

It took humans 10,000 years to learn how to grow most of the crops we now take for granted. Along the way, we despoiled most of the land we worked, often turning verdant, natural ecozones into semi-arid deserts. Over 60% of the human population now lives vertically in cities.
The time has arrived for us to learn how to grow our food that way, too. If we do not, then in just another 50 years, 3 billion people will surely go hungry, and the world will be a very unpleasant place in which to live.
This well-developed project from Columbia University walks through the realities, possibilities and constraints of multi-storey, urban, high-rise farming:
