•updated: 2/13/2011 Whether it's to understand potential attack vectors or simply for the fun of it, learning the basics of hacking is something that a lot of people aspire to. Here's our list of the top tutorial based hacking sites. Introduction Films like Swordfish and Hackers have made hacking seem cool, a lifestyle choice almost.

Pop a “miracle berry” into your mouth, and you might wonder if it was named by an overreaching marketing department.
The small red fruit tastes of very little – it has a “mildly sweet tang… [like] a less flavorful cranberry”. But it’s not the taste of the fruit itself that matters. To understand why the berry gets its name, you need to eat something acidic. The berries have the ability to make sour foods taste deliciously sweet. The Last Orion. Dylex. Singularity & Futurism.

Scientists create first step toward creating ‘inorganic life’ Inorganic chemical cells (iCHELLs) (credit: University of Glasgow) University of Glasgow scientists have taken their first tentative steps towards creating “life” from inorganic chemical cells (iCHELLS), potentially defining the new area of “inorganic biology.”
“What we are trying do is create self-replicating, evolving inorganic cells that would essentially be alive. You could call it inorganic biology,” said Professor Lee Cronin, University of Glagow Gardiner Chair of Chemistry in the College of Science and Engineering. The cells can be compartmentalized by creating internal membranes that control the passage of materials and energy through them, meaning several chemical processes can be isolated within the same cell — just like biological cells. The researchers say the cells, which can also store electricity, could potentially be used in all sorts of applications in medicine, as sensors or to confine chemical reactions.
Artificial blood vessels created on a 3D printer. 16 September 2011Last updated at 11:49 By Katia Moskvitch Technology reporter, BBC News Artificial blood vessels could help those in urgent need of an organ transplant Artificial blood vessels made on a 3D printer may soon be used for transplants of lab-created organs.
Until now, the stumbling block in tissue engineering has been supplying artificial tissue with nutrients that have to arrive via capillary vessels. A team at the Fraunhofer Institute in Germany has solved that problem using 3D printing and a technique called multiphoton polymerisation. The findings will be shown at the Biotechnica Fair in Germany in October. We are not only eating 'materials', we are also eating 'information' In a new study, Chen-Yu Zhang's group at Nanjing university present a rather striking finding that plant miRNAs could make into the host blood and tissues via the route of food-intake.
Moreover, once inside the host, they can elicit functions by regulating host "target" genes and thus regulate host physiology. MicroRNAs are a class of 19-24 nucleotide non-coding RNAs that do not code for proteins. MicroRNAs bind to target messenger RNAs to inhibit protein translation. In previous studies, the same group has demonstrated that stable microRNAs (miRNAs) in mammalian serum and plasma are actively secreted from tissues and cells and can serve as a novel class of biomarkers for disease and act as signaling molecules in intercellular communication.
Nanotube Cables Hit a Milestone: As Good as Copper. For the first time, researchers have made carbon-nanotube electrical cables that can carry as much current as copper wires.
These nanotube cables could help carry more renewable power farther in the electrical grid, provide lightweight wiring for more-fuel-efficient vehicles and planes, and make connections in low-power computer chips. Researchers at Rice University have now demonstrated carbon-nanotube cables in a practical system and are designing a manufacturing line for commercial production.

As anyone familiar with the phrase 'man-flu' will know women consider themselves to be the more robust side of the species when it comes to health and illness.
Now new research, published in BioEssays, seems to support the idea. The research focuses on the role of MicroRNAs encoded on the X chromosome to explain why women have stronger immune systems to men and are less likely to develop cancer. The research, led by Dr Claude Libert from Ghent University in Belgium, focused on MicroRNA, tiny strains of ribonucleic acid which alongside DNA and proteins, make up the three major macromolecules that are essential for all known forms of life. "Statistics show that in humans, as with other mammals, females live longer than males and are more able to fight off shock episodes from sepsis, infection or trauma," said Libert.
