You may love stories about the end of the world, but that's probably because, deep down, you don't believe it could ever happen. But that's not because you're realistic. It's actually a quirk of the human brain, recently explored by a group of neuroscientists, which prevents us from adjusting our expectations about the future — even if there's good evidence that bad things are about to happen.

There's no question, drugs work in treating disease. But can they work better, and safer? In recent years, researchers have grappled with the challenge of administering therapeutics in a way that boosts their effectiveness by targeting specific cells in the body while minimizing their potential damage to healthy tissue. The development of new methods that use engineered nanomaterials to transport drugs and release them directly into cells holds great potential in this area. And while several such drug-delivery systems — including some that use dendrimers, liposomes or polyethylene glycol — have won approval for clinical use, they have been hampered by size limitations and ineffectiveness in accurately targeting tissues.

Sentiment mining showed a sharp change in tone around Egypt ahead of President Mubarak's ousting Kalev Leetaru, from the University of Illinois' Institute for Computing in the Humanities, Arts and Social Science, presented his findings in the journal First Monday. Mood and location The study's information was taken from a range of sources including the US government-run Open Source Centre and BBC Monitoring , both of which monitor local media output around the world. Reports were analysed for two main types of information: mood - whether the article represented good news or bad news, and location - where events were happening and the location of other participants in the story. The Nautilus SGI supercomputer crunched the 100 million articles

Statistical Data Mining Tutorials
Advertisment: In 2006 I joined Google. We are growing a Google Pittsburgh office on CMU's campus. We are hiring creative computer scientists who love programming, and Machine Learning is one the focus areas of the office. We're also currently accepting resumes for Fall 2008 intenships. If you might be interested, feel welcome to send me email: awm@google.com . The following links point to a set of tutorials on many aspects of statistical data mining, including the foundations of probability, the foundations of statistical data analysis, and most of the classic machine learning and data mining algorithms.
A dramatic and surprising magnetic effect of light discovered by University of Michigan researchers could lead to solar power without traditional semiconductor-based solar cells. William Fisher, a doctoral student in applied physics, performing research on laser-induced magnetism. The researchers found a way to make an "optical battery," said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics.

This is a list of some of the major unsolved problems in physics . Some of these problems are theoretical , meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental , meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail. Is the theory of cosmic inflation correct, and if so, what are the details of this epoch? What is the hypothetical inflaton field giving rise to inflation? If inflation happened at one point, is it self-sustaining through inflation of quantum-mechanical fluctuations , and thus ongoing in some impossibly distant place?

Since 2007, we've been working on making Java web application development easier. Play started as an internal project at Zenexity and was heavily influenced by our way of doing web projects: focusing on developer productivity, respecting Web architecture, and from the start employing a fresh approach to packaging conventions.
Biology That Makes Us Tick: Free Stanford Course by Robert Sapolsky | Open Culture
First thing you need to know: Before doing anything else, you should simply click “play” and start watching the video above. It doesn’t take long for Robert Sapolsky , one of Stanford’s finest teachers, to pull you right into his course. Better to watch him than listen to me. Second thing to know: Sapolsky is a MacArthur Fellow, a world renowned neurobiologist, and an adept science writer best known for his book, Why Zebras Don’t Get Ulcers . Much of his research focuses on the interplay between the mind and body (how biology affects the mind, and the mind, the body), and that relationship lies at the heart of this course called “Human Behavioral Biology.” Now the third: Human Behavioral Biology is available on YouTube and iTunes for free.
Physicists Slow Speed of Light
Light, which normally travels the 240,000 miles from the Moon to Earth in less than two seconds, has been slowed to the speed of a minivan in rush-hour traffic -- 38 miles an hour. An entirely new state of matter, first observed four years ago, has made this possible. When atoms become packed super-closely together at super-low temperatures and super-high vacuum, they lose their identity as individual particles and act like a single super- atom with characteristics similar to a laser. Such an exotic medium can be engineered to slow a light beam 20 million-fold from 186,282 miles a second to a pokey 38 miles an hour.Voltage is the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts. It measures the potential energy of an electric field to cause an electric current in an electrical conductor. Most measurement devices can measure voltage. Two common voltage measurements are direct current (DC) and alternating current (AC).
