Examining the Brain’s Four Lobes: Frontal, Parietal, Temporal, and Occipital

The neocortex is divided into four major lobes: the frontal lobe, the parietal lobe, the temporal lobe, and occipital lobe. These lobes are further divided into different regions. The frontal lobes are [more…]

Examining the Thalamus and the Limbic System

The neocortex interacts with the rest of the brain primarily through a structure called the thalamus. The thalamus, which is underneath (and hierarchically below) the neocortex, functions like a command [more…]

The Types and Function of Neurons

The nervous system consists of the central nervous system (the brain and spinal cord), the peripheral nervous system (the sensory and motor neurons), and the autonomic nervous system [more…]

Understanding the Role of the Neocortex

When you look at a human brain from the top or sides, almost everything you see is neocortex. It’s called “neo” because it is a relatively recent invention of mammals. Prior to mammals, animals like reptiles [more…]

Looking at the Left and Right Hemispheres of the Brain

The brain is composed of two nearly mirror-image lobes called the left and right hemispheres. The left hemisphere receives most inputs from and controls mostly the right side of the body. This hemisphere [more…]

Neuroscience For Dummies Cheat Sheet

The most complex structure in the universe (that we know of) is the three pound mass of cells within your skull called the brain. The brain consists of about 100 billion neurons, which is about the same [more…]

What is Nanotechnology?

The scientific field of nanotechnology is still evolving, and there doesn’t seem to be one definition that everybody agrees on. It is known that nano deals with matter on a very small scale: larger than [more…]

The Evolution of Nanotechnology

Nanotechnology has been around as a recognized branch of science for only about fifty years, so it’s a baby compared to physics or biology. If you remember high school science, you know something about [more…]

Nanotechnology: Top Down or Bottom Up?

How our knowledge of nanoparticles should be used has been a subject of much debate. Nanotechnologists have offered two approaches for fabricating materials or manipulating devices using nanotechnology [more…]

The Pervasive Impact of Nanotechnology

Nanotechnology pulls in information from physics, chemistry, engineering, and biology to study and use materials at the nano level to achieve various results. It will have a significant impact on almost [more…]

Early History of Nanotechnology: 1930-1980

To really understand the big picture of nanotechnology, it is helpful to review the timeline of discoveries that brought us to the current understanding of the science. The history forms the foundation [more…]

Government Funding for Nanotechnology Research Labs

In the United States, the federal government provides significant funding for nanotechnology development through the National Nanotechnology Initiative [more…]

The Role of Companies in Nano Development

Many companies developing nanotechnology products have licensed techniques that were developed at universities or national labs. They take these techniques and work to develop products. They pay to put [more…]

What Can be Done with Nanotechnology Today?

Much of what people talk about doing with nanotechnology lies in the future. However, you can find many examples of nanotechnology making a difference today. [more…]

Nanotechnology Applications Under Development

While there are many applications of nanotechnology being used today, others are still in development and may become available in only a few years to a decade or so. [more…]

Speculation on Future Nanotechnology Applications

Even though much has been accomplished in developing nanotechnology applications, much more is still deemed possible. Three of the most fascinating examples — all in the speculative phase — are the space [more…]

Diamondoid: A Flawless Nanoparticle

While the name diamondoid may conjur thoughts of engagement rings and tennis bracelets, it is much more than the bling of the nanotechnology field. Diamondoid is projected to have a strength 50 times that [more…]

Nanotechnology Research Involving Iron and Iron Oxide Nanoparticles

Any material at the nanoscale is a nanoparticle. Nanoparticles are so small they contain just a few atoms to a few thousand atoms, as opposed to bulk materials that might contain billions of atoms. This [more…]

Platinum Nanoparticles to Prevent Air Pollution

Any material at the nanoscale is a nanoparticle. Nanotechnology research into the use of platinum nanoparticles shows promise for reducing the cost of using platinum in catalytic converters and other pollution [more…]

Nanotechnology Research into the Uses of Gold Nanoparticles

Nanotechnology researchers are looking into possibilities of using gold at the nanoscale to target drug deliveries, clean up the environment, and even treat persons suffering from hyperthermia. [more…]

Titanium Dioxide Nanoparticles Make Better Sunscreen and More

Nanotechnology researchers have already made a clear sunscreen using titanium dioxide nanoparticles. They are also researching ways to use this nanotech material to kill bacteria and destroy cancer tumors [more…]

Silicon Nanoparticles Make Ever Smaller Electronics Possible

Silicon has been used in the manufacture of electronics for years. Just as it seemed that electronics couldn’t get any smaller, nanotechnology scientists have discovered ways to use silicon nanoparticles [more…]

Palladium Nanoparticles May Reduce Cost of Fuel Cells

Laboratories devoted to nanotechnology research are exploring the possibilities of using palladium nanoparticles to reduce the cost of fuel cells and catalytic converters. They have even found that palladium [more…]

Magnets and Nanotechnology

Nanotechnology scientists are conducting research to determine whether magnetic nanoparticles can be used to make magnets stronger using less material. This research is being done with neodymium, iron, [more…]

Absorb Neutrons with Boron Nanoparticles

Scientists studying the applications of nanotechnology in medical care have found that boron nanoparticles show promise in the fight against cancer.

Boron, in its bulk form, is an element that is used to [more…]
