NASA/IBEX Provides First View of the Solar System’s Tail

NASA’s Interstellar Boundary Explorer, or IBEX, recently mapped the boundaries of the solar system’s tail, called the heliotail.

By combining observations from the first three years of IBEX imagery, scientists have mapped out a tail that shows a combination of fast and slow moving particles.

The entire structure twisted, because it experiences the pushing and pulling of magnetic fields outside the solar system.

How Does a Transistor Work?

How does a transistor work? Our lives depend on this device.

After the transistor was invented in 1947 one of the first available consumer technologies it was applied to was radios, so they could be made portable and higher quality. Hence the line in ‘Brown-eyed Girl’ - “going down to the old mine with a transistor radio.”

But more important to our lives today, the transistor made possible the microcomputer revolution, and hence the Internet, and also TVs, mobile phones, fancy washing machines, dishwashers, calculators, satellites, projectors etc. etc.

A transistor is based on semiconductor material, usually silicon, which is ‘doped’ with impurities to carefully change its electrical properties. These n and p-type semiconductors are then put together in different configurations to achieve a desired electrical result. And in the case of the transistor, this is to make a tiny electrical switch. These switches are then connected together to perform computations, store information, and basically make everything electrical work intelligently.

8-bit Cinema: G.I. Joe Retaliation

CineFix presents G.I. Joe: Retaliation retold via old-school 8-bit (& a little 16-bit :) game tech. No quarters or controllers required!

8-bit Cinema “gamifies” your favorite Hollywood Blockbusters into 80’s arcade and NES inspired action!

Today we present G.I. Joe: Retaliation in the form of an 8 bit video game!

Summary: The G.I. Joes are not only fighting their mortal enemy Cobra; they are forced to contend with threats from within the government that jeopardize their very existence.

G.I. Joe: Retaliation in Blu-ray and DVD (pre-order).

Why Does The Placebo Effect Work?

The placebo effect is a long-recognised phenomenon that has played an important part in the history of medicine — from the healing powers of Stonehenge to administering placebo drugs to modern day patients. But it’s not until recently that science has begun to truly understand how the placebo effect really works.

Professor Nicholas Humphrey asks why placebos work and reveals their central paradox: If we can effectively cure ourselves by taking placebo medicine, why don’t we just heal ourselves straight away?

Exploring this paradox from the perspective of evolution, Professor Humphry looks at the associated costs and benefits of pain or illness. How can placebo medications readdress this balance and is a “dose of contrived optimism” just what the doctor ordered?

How Big is the Ocean?

While the Earth’s oceans are known as five separate entities, there is really only one ocean. So, how big is it?

As of 2013, it takes up 71% of the Earth, houses 99% of the biosphere, and contains some of Earth’s grandest geological features.

Scott Gass reminds us of the influence humans have on the ocean and the influence it has on us.
